couple of large programs and the end
of significant Third Frontier research
investments from the State of Ohio. To
fill the gap, there has been a significant
influx of core program, basic science
support from federal funding agencies.
We had a very strong proposal-writing
season, and a number of new programs
have now begun, some of which are quite
substantial. The largest new-starts this
year include research in multimaterials
systems with adaptive microstructures
(Fraser, Mills, Wang, Williams, Zhao),
lightweight hydrides for hydrogen storage
(Zhao), environmentally conscious
corrosion inhibition (Frankel, Buchheit),
and ductile and fracture resistant bulk
metallic glasses (Flores, Windl).
To be sure, the changes in front of us are
exciting and challenging. I think it is fair
to say that we will have to be at our best to
manage them successfully. To learn more
about these and many other activities
going on in MSE, I invite you to browse
this issue of Watts News or visit our
website at mse.osu.edu. We are primed
for an engaging and rewarding year and
hope the same awaits you. As always, if
your travels bring you to campus, please
stop in and say hello.

Greetings and welcome to the 2009
edition of Watts News! I invite you to
peruse this year’s issue to learn about
all the activities and accomplishments
going on in Materials Science and
Engineering.
As was the case everywhere, our year
unfolded against the backdrop of a
significant economic downshift. I am
often asked how this affected MSE. Some
consequences have been prompt. The job
market for BS degree holders went from
all-time best to all-time worst in a matter
of a very few months. Opportunities for
graduate degree holders have remained
strong enough for all those seeking
positions to find them. Other impacts are
still in front of us and not well defined.
Notable in this regard is the potential
decrease in the state subsidy to the
University due to continued weakness
in state tax revenues. How this will play
out within the University in the next two
years is not known, but MSE was fiscally
conservative during the good times, and
we are positioned well should cuts come
our way.
The economic picture created much
uncertainty and distraction this past year,
but a number of important initiatives
were set in motion. After years of debate
and a number of false starts, the Board of
Trustees moved this past April to approve
the implementation of a semesters-based
calendar. The University will begin its
new semester format in Autumn 2012.
The faculty is well into defining new
undergraduate and graduate curricula.
On another front, after discussions that
have also unfolded over some time, the
faculties of Welding Engineering and
Materials Science and Engineering have
voted to realign into a single department.
The new department will operate under
the Materials Science and Engineering
banner and will support both MSE
and WE undergraduate and graduate
degree programs. This alignment will
immediately push our faculty size into
the mid-30s range, expand our research
base, and move our undergraduate and
graduate populations to 250 and 170
students respectively. It will also add
significant new lab and office space
on west campus. Additional details on
these major changes can be found in the
following pages.
Our faculty and student researchers have
had a focused and productive year. At the
close of 2008, we counted 104 graduate
students in the program, up from 86 in
2007 and we welcomed an incoming pool
of 25 new graduate students this fall. This
past year, faculty researchers and their
groups authored 170 publications, up
from 130 a year before. A demographic,
I am especially pleased with is our PhD
degree production; 17 in 2008, up from
6 in 2007. Our research expenditures
were down from $13.4 million in 2007
to $8.9 million in 2008. This drop was
associated with the conclusion of a

ResearchTitanium Research
Titanium and Titanium alloys (hereafter
titanium) are attractive because of
their structural efficiency and their
resistance to degradation in a wide
range of environments. Titanium also
is expensive. Nevertheless, it has gained
wide acceptance for aircraft, aircraft
and rocket propulsion systems, and for
chemical processing applications.
MSE at Ohio State has by far the most
comprehensive academic titanium
research program in the US and most
likely the free world. The major thrusts of
our program are computational modeling
of many aspects of titanium behavior,
detailed studies of microstructure
property relationships, mechanisms that
govern microstructure evolution, and
mechanisms of environmental attack.
The faculty members that are most
active in this effort include Professors
Fraser, Mills, Wang, Williams, and
Frankel. Professor Somnath Ghosh from
Mechanical Engineering also is involved
in several of these projects. Currently,
there are active research projects on
some aspect of titanium funded by The
Office of Naval Research, The Air Force
Research Laboratories, The Federal
Aviation Administration, The Defense
Research Project Agency and The Air
Force Office of Scientific Research. Total
external funding is ~$2M. In order to
leverage our expertise, we have active
ongoing collaborations with faculty
members who have complimentary skills
from Drexel University, Carnegie Mellon
University, The University of Michigan,
and Cornell University. In case you are
wondering, we have some excellent
faculty member colleagues at “Big Blue”
but none of them play football. (Maybe
they should?)
Some specific research activities include
the following:
Computational methods for
representing the three dimensional
microstructure of titanium in
digital form are being developed.
This will enable incorporation
of microstructure directly in
micromechanics models of
mechanical properties such as
strength, fracture toughness, and
fatigue. An integral part of this
effort has been development
of Bayesian neural networks
for correlating properties with
specific microstructural features.
OSU is broadly acknowledged as a world
leader in applying these methods to
titanium.
Another project is studying the root
cause of dwell fatigue in titanium.
Some titanium alloys (e.g. Ti-6Al-2Sn-
4Zr-2Mo) exhibit a large reduction
in fatigue strength when the load is
held at maximum value rather than
continuously cycled. Our research at
OSU has been able to account for this
effect qualitatively by coupling mechanics
modeling and detailed characterization.
In essence, room temperature creep leads
to internal load re-distribution which
triggers early crack initiation with an
attendant reduction in fatigue life. The
dwell effect can lead to non-conservative
designs which affect product life.
The use of metastable β titanium alloys
is growing. For example, alloys from this
class are now used in the landing gear of
the Boeing 777 and 787. Studies at OSU
are focused on understanding the basic
mechanisms of microstructure evolution
and the effects of
microstructural
variation on
strength, ductility
and fatigue
resistance. These
studies combine
our expertise
in phase field
modeling with our
characterization
capability which
utilizes the world
class Campus
Electron Optics
Facility (ceof.ohio-
state.edu) housed
in the basement
of Fontana Labs. If
you have not seen
this facility, you are
invited to schedule
a tour.
Still another activity involves the use of
friction stir processing of cast and hot
isostatically pressed Ti-6Al-4V to refine
the surface microstructure, thereby
improving the resistance to fatigue crack
initiation at lifetimes of 104 to 106 cycles
to failure. As part of this study, detailed
fractographic studies of failed specimens
has shown conclusively that the facets
seen on fatigue fracture surfaces are
the result of cyclic crack progression,
not cleavage as had been reported in
the literature. This result has major
implications for estimating the number
of load cycles after crack initiation. This
can be critical during failure analysis of
titanium components.
Studies to understand the effects
of microstructure on corrosion
susceptibility also are being conducted.
These studies couple our considerable
expertise in corrosion with our
microstructural characterization
capabilities.

Electrochemical Microscopy: Mapping Electrochemical Behavior onto Microstructurally Complex Metallic Alloys
Alloying enables strengthening and
toughening of metallic materials for
all manner of structural engineering
applications. In fully processed alloys,
alloying additions are often concentrated
into discrete particles, either intentionally
by thermomechanical processing, or
unavoidably due to low solid solubility
of inherent impurity elements. The
properties of particles are different
because their composition differs
radically from the majority phase of
the alloy. In the case of electrochemical
properties, differences lead to
susceptibility to localized corrosion.
Indeed, many microstructurally
complex, high-performance alloys are
often saddled with a localized corrosion
vulnerability that must be managed in
service through coatings, inhibitors, or
environmental controls.
Researchers in the Fontana Corrosion
Center (Prof. R.G. Buchheit and students)
and at Monash
University in
M e l b o u r n e ,
Australia (Dr.
N. Birbilis and
students) have
collaborated over
the past several
years to measure
the electro-
chemistry of
i n t e r m e t a l l i c
particles in
high strength
aluminum alloys
to understand
their role
in localized
corrosion and to
develop predictive
corrosion damage
a c c u m u l a t i o n
models. An electrochemical microcell has
been used to measure the electrochemical
behavior of naturally occurring particles,
or phase-pure intermetallic compound
crystals specially synthesized for
electrochemical work (Figure 1). To date,
over 40 unique intermetallic compounds
found in aluminum alloys have been
characterized.
In the newest line of work, methods
are being developed to map the
measured electrochemical properties
of intermetallic compounds onto real
or simulated alloy microstructures to
understand and predict spatial patterns
of localized corrosion in an approach
that amounts to “electrochemical
microscopy”.
Using scanning electron microscopy
(SEM), x-ray microchemical analysis,
and electron backscatter methods, it
is possible to image and identify the
intermetallic compound particles in
a microstructure. In Z-contrast SEM
images, the gray-scale contrast of an
intermetallic compound is often distinct
from that of the other phases present
(Figure 2). As a result, it is possible to
associate electrochemical characteristics
such as electrochemical potential, or
reaction rate with a gray scale contrast
level. Once electrochemistry has been
associated with contrast level , an image
representing the spatial variation in
electrochemical reaction rate across the
microstructure can be constructed.
The spatial variation of
electrochemical reaction rate
shown in Figure 2 is an example
of this approach. These figures
capture the polarity (anodic
or cathodic) and magnitude
of the electrochemical
reaction rate measured on the
different intermetallic phases
present in the alloy in dilute
chloride solutions at ambient
temperature but different
solution pH. When rendered in
3-D, sites of cathodic reaction
due to oxygen or hydrogen
reduction appear as deep
blue wells, and sites of anodic
reaction appear as bright red
spikes (Figure 3, top). Sites of

New Way to Make Sensors that Detect Toxic Chemicalsby Pam Frost Gorder
MSE researchers have developed a new
method for making extremely pure,
very small metal-oxide nanoparticles.
They are using this simple, fast, and low-
temperature process to make materials
for gas sensors that detect toxic industrial
chemicals (TICs) and biological warfare
agents. The researchers described their
work in a recent issue of the journal
Materials Chemistry and Physics.
Patricia Morris, associate professor of
materials science and engineering at Ohio
State, leads a team of researchers who
develop solid materials that can detect
toxic chemicals. The challenge, she said,
is to design a material that reacts quickly
and reliably to a variety of chemicals,
including TICs, when incorporated into
a sensor. “These are sensors that a soldier
could wear on the battlefield or a first
responder could wear to an accident at a
chemical plant,” Morris said.
The material under study is nickel oxide,
which has unusual electrical properties.
Other labs are studying nickel oxide for
use in batteries, fuel cells, solar cells,
and even coatings that change color. But
Morris, along with Ohio State doctoral
student Elvin Beach, is more interested in
how nickel oxide’s electrical conductance
changes when toxic chemicals in the
air settle on its surface. Beach applies
a thin coating of the material onto
microelectro-mechanical systems (made
in a similar fashion to computer chips),
with a goal of identifying known toxic
substances.
The design works on the same general
principle as another, more familiar sensor.
“The human nose coordinates signals
from hundreds of thousands of sensory
neurons to identify chemicals,” Beach
said. “Here, we’re using a combination
of electrical responses to identify the
signature of a toxic chemical.”
The key to making the sensor work
is how the nickel oxide particles are
made. Beach and Morris have
devised a new synthesis method
that yields very small particles--
which provide the sensor a large
surface area with which to capture
chemical molecules from the air
--and very pure particles--which
enable the sensor to detect even
small quantities of a substance.
Each particle of nickel oxide
measures only about 50 atoms
across--that’s equivalent to five
nanometers.
Beach described the synthesis
method in very simple terms.
“Basically, you mix everything
together in a pressure vessel, pop
it in the oven, rinse it off and it’s
ready to use,” he said. Of course,
for the process to go smoothly,
the researchers
have to meet
specific conditions
of temperature
and pressure, and
leave the material
in the pressure
cooker for just the
right amount of
time. They found
they can make the
particles in as little
as twelve hours,
but no more than
twenty-four hours.
“Too short a time,
and the nickel oxide
doesn’t form, too
long and it reduces
to metallic nickel,”
Beach explained. After he removes the
nickel oxide from the pressure cooker,
he washes it in a common solvent to
free up the nanoparticles. At that point,
the material is ready to use. Most other
synthesis methods require another
additional step, a high-temperature heat
treatment.
Starting with a microsensor silicon
chip array provided by collaborators at
the National Institute of Standards and
Technology (NIST), Beach adds a layer of
particles using a device called a picoliter
drop dispenser (a picoliter is a trillionth
of a liter). He describes the dispenser
intense cathodic activity are expected
to sustain attack leading to large pits
around intermetallic particles. Sites of
intense anodic activity are expected to be
short-lived small pits where intermetallic
particles are dissolved from the alloy
selectively.
A comparison of the reaction rate
projection from electrochemical
microscopy correlates remarkably well
with localized corrosion morphologies
developed on high-strength aluminum
alloy 7075 (Al-Zn-Mg-Cu) samples that
were allowed to corrode freely during
exposure to aqueous solutions in separate
experiments (Figure 3, bottom). The
ability of the electrochemical microscopy
approach to correctly forecast localized
corrosion morphologies illustrates the
potential of the method.
Ongoing work is aimed at associating the
full current-potential electrochemical
response on a pixel-by-pixel basis to
enable exploration of the effects of
changing environmental conditions on
alloy electrochemistry and localized
corrosion damage accumulation.

as a kind of inkjet printer that places a
droplet of a liquid suspension containing
particles onto a surface--in this case, the
chips. According to Morris, this is the
first time that nickel oxide nanoparticles
have been applied in this way.
But to Beach, the most important “first”
to come out of the study is their discovery
of the reaction pathway--that is, the
various chemical steps that take place
inside the pressure cooker during the
synthesis of the material. Now that the
researchers know the reaction pathway,
they can devise ways to add chemical
dopants to the nanoparticles. Dopants
would change the function of the sensor,
for instance, to speed the response rate.
A one-gram batch of nickel oxide
nanoparticles costs about $5.00 to
make; one chip carries four nanograms
(billionths of a gram) of material, so each
sensor costs only pennies to fabricate.
Other applications could include exhaust
or pollution monitoring and air quality
monitoring.
Collaborators on the project include
Steve Semancik and Kurt Benkstein at
NIST. Study coauthors include: Krenar
Shqau, an Ohio State postdoctoral
researcher; Samantha Brown, then an
undergraduate student visitor from
Northwestern University who will join
Ohio State this fall to pursue her doctorate
in Chemistry; and Steven Rozeveld at
Dow Chemical Co., who helped Beach
produce electron microscope images of
the nanoparticles. This work is
funded by the National Science
Foundation and The Ohio State

Gas Sensor Technology using “Nano-flowers”
Results from the Sensor
Array Technology group
led by Associate Professor
Patricia Morris, have
recently been featured
in The Ohio State
University’s Research
News for methods to
fabricate sensors that
detect hazardous gases. The goal is to
design a material that responds quickly
and accurately to a variety of chemicals
at very low concentrations. Long-term
stability is also an important property of
the sensor device. These sensor devices
are similar to the human nose which
coordinates signals from hundreds of
thousands of sensory neurons to identify
gases. Similarly, the artificial sensor uses
a combination of electrical responses
from sensor arrays to identify the
concentration of a specific gas.
The group’s efforts include synthesizing
metal-oxide particles in the form of
nanoparticles, nano-structured materials,
and hollow particles for use as the sensing
material to increase sensor performance.
NiO and SnO2 nanoparticles are created
with a particle size between five and
ten nanometers. Five nanometers
(billionths of a meter) is approximately
50 atoms in diameter. In order to make
the particles, precursors are placed in
a Teflon®-lined pressure vessel that is
heated in an oven. The combination of
temperature and pressure involving the
correct precursors leads to the formation
of nanoparticles. The small particles give
the sensor a large surface area to capture
molecules from the air which enable the
sensor to detect very small quantities of
a substance. ano-structured materials
including TiO2, SnO
2, NiO, and ZnO are
also synthesized for sensor devices to
increase the surface area of the material.
SnO2 nano-structured particles,
sometimes referred to as “nanoflowers”
due to their appearance (see images).
The many surfaces that extend out
from the material are advantageous for
adsorption and detection of hazardous
gases. The material is a few microns
(millionths of a meter) in
diameter, but has nano-sized
features. These materials
have shown fast response
and recovery times (quicker
detection) compared to
other metal-oxide materials
used for sensors.
Once the metal-oxide
materials are synthesized,
the particles are suspended
in liquids designed to have
the proper viscosity and
surface tension in order
to deposit the materials
controllably on sensor
platforms. The group uses a
sophisticated inkjet printer
The high surface area produced by this technique is advantageous for gas sensor devices.

Double perovskite crystal structure
Buffer Layer Design For Double Perovskites
Associate Professor Patricia Morris and
her students are presently studying thin
film growth of complex oxides. Using a
pulsed laser deposition system, a laser
beam is shot at a solid oxide target where it
ablates the surface, allowing atomic layers
of material to deposit onto a substrate.
The complex oxides of interest are
known as double perovskites because of
their unique crystal structure. Materials
in this family have interesting properties
like ferroelectricity, superconductivity,
colossal magnetoresistance, and
Researchers Find Better Way to Manufacture Fast Computer Chipsby Pam Frost Gorder
MSE engineers at The Ohio State
University are developing a technique
for mass producing computer chips
made from the same material found in
pencils. Experts believe that graphene-
-the sheet-like form of carbon found
in graphite pencils--holds the key to
smaller, faster electronics. It might also
deliver quantum mechanical effects that
could enable new kinds
of electronics.
Until now, most
researchers could only
create tiny graphene
devices one at a time,
and only on traditional
silicon oxide substrates.
They could not control
where they placed
the devices on the
substrate, and had to
connect them to other
electronics one at a
time for testing.
In a paper published
in the March 26, 2009
issue of the journal
Advanced Materials,
OSU Professor Nitin
Padture and his
colleagues describe
a technique for
stamping many
graphene sheets onto a substrate at once,
in precise locations. “We designed the
technique to mesh with standard chip-
making practices,” said Padture, College
of Engineering Distinguished Professor
in Materials Science and Engineering.
“Graphene has huge potential; it’s been
dubbed ‘the new silicon,’” said Padture,
who is also director of Ohio State’s Center
for Emergent Materials (cem.osu.edu).
“But there hasn’t been a good process for
high-throughput manufacturing it into
chips. The industry has several decades
of chip-making technology that we can
tap into, if only we could create millions
of these graphene structures in precise
patterns on predetermined locations,
repeatedly. This result is a proof-of-
concept that we should be able to do just
that.”
Graphene is made of carbon atoms
arranged in a hexagonal pattern
resembling chicken wire. In graphite,
many flat graphene sheets are stacked
together. “Think of a stack of graphene
sheets in graphite as a deck of cards.
When you bring it contact with the
silicon oxide and pull it away, you can
‘split the deck’ near the point of contact,
leaving some layers of graphene behind.”
that dispenses picoliter drop volumes
onto very small substrates. The diameter
of the orifice for the print-head where the
particle-laden suspension passes through
is 50 microns. Therefore, the particle size
of the material (described previously) is
important during deposition in order to
not clog the print-head.
The microsensor substrate consists of
a silicon chip fitted with a platinum
heater and gold electrodes to monitor
the material’s electrical resistance. The
change in the material’s resistance
corresponds to a change in the
surrounding atmosphere. More research
is currently being performed on the
metal-oxide synthesis, deposition, and
testing of these sensor devices. This
work is funded by the National Science
Foundation and the Orton Research
Foundation.

half-metallicity. These properties
are very important when applied to
electronics. Until recently, however,
these characteristics were not observable
unless the materials were kept very cold.
New research is being done on materials
that display these properties at or above
room temperature conditions, which
make them far more useful for industrial
purposes.
One such oxide, Sr2FeMoO
6 (SFMO), is
of interest for its magnetic properties and
possible usage in magnetic data storage.
However, because of its chemistry, film
growth of this oxide is very challenging.
In collaboration with the Center for
Emergent Materials (CEM), Dr. Morris
and her students are studying buffer layer
materials as a tool to foster the growth of
these complex compounds. Sr2GaTaO
6
(SGT) is a similar double perovskite
that has similar lattice parameters, is
easier to grow, and will not interfere
magnetically with SFMO. Films of SGT
have been made and characterized
with x-ray diffraction and Rutherford
backscattering spectroscopy. Work is
also being done to design specific buffer
layers to match desired perovskites based
on the lattice size. Bulk studies have
shown that by adding different amounts
of Al to SGT, lattice parameters will
change systematically, therefore creating
a wide range of possible buffer layers.

Photovoltaics Researchers Join Forces to Improve Solar Cells
Ohio State engineers are taking
advantage of advancements in materials
for electronics to develop more efficient
and affordable solar technologies. Solar
cells, generally made of silicon, currently
are not efficient at harnessing solar
energy. Now, however, engineers are
investigating how indium, gallium, and
nitrogen could be used to make wide
bandgap semiconductors for solar cell
production.
“The key to success is being able to
grow the semiconductor crystals
without generating defects that drop
the solar conversion efficiency,” says
Assistant Professor Roberto Myers,
who collaborates on photovoltaic work
with Siddharth Rajan, also an assistant
professor. Both have dual appointments
in electrical and computer engineering
and in materials science and engineering,
enabling them to take advantage of
resources provided by both departments
and by the university’s Institute for
Materials Research.
“Advanced semiconductor materials are
capable of using a much higher fraction
of solar energy than silicon and are, in
fact, already being used to power space
vehicles,” Rajan says. “However, they
are more expensive than silicon and
are, therefore, not used for terrestrial
applications yet. Our work aims to come
up with new innovative ways that would
reduce the cost of these solar cells but still
ensure that they provide high efficiency.”
Myers and Rajan worked together
to procure a new molecular beam
epitaxy system, which allows them to
grow the various layers of III-Nitride
semiconductor crystal structures with
nanometer-scale control. They also
use another new tool, a metal organic
chemical vapor deposition system, to
enable epitaxial growth of semiconductors
and nanostructures based on arsenides,
phosphides, antimonides, and dilute
nitrides.
Rajan brings expertise in electrical
measurement to the project, while Myers
conducts the optical measurements.
Together, the two can explore the potential
of these lesser-known materials to
determine how the materials’ properties
could be harnessed for solar energy.
Researchers have shown that a single
sheet, or even a few sheets, of graphene
can exhibit special properties. One such
property is very high mobility, in which
electrons can pass through it very quickly,
a good characteristic for fast electronics.
Another is magnetism: magnetic fields
could be used to control the spin of
graphene electrons, which would enable
spin-based electronics, also called
spintronics. Yet another characteristic is
how dramatically graphene’s properties
change when it touches other materials.
That makes it a good candidate material
for chemical sensors.
In this method, Padture and his Ohio
State colleagues carved graphite into
different shapes--a field of microscopic
pillars, for example--and then stamped
the shapes onto silicon oxide surfaces.
In this first series of experiments, they
were able to stamp high-definition
features that were ten layers thick, or
thicker. The graphite stamp can then
be used repeatedly on other locations
or substrates, potentially making this a
mass-production method.
They used three different kinds of
microscopes--a scanning electron
microscope, optical microscope, and
atomic force microscope--to measure
the heights of the features and assure
that they were placed precisely on the
substrate. They eventually hope to stamp
narrow features that are only one or two
layers thick, by stamping on materials
other than silicon oxide.
In computer simulations, they found
that each material interacts differently
with the graphene. So success might rely
on finding just the right combination of
substrate materials to coax the graphene
to break off in one or two layers. This
would also tailor the properties of the
graphene.

“We need people with skill sets in
processing, materials growth, optics, and
electronics, and to integrate those skill
sets to solve this problem,” says Steven
Ringel, professor and Neal A. Smith
Endowed Chair in Electrical Engineering
and director of the Institute for Materials
Research, adding that Rajan and Myers,
who joined Ohio State in autumn 2008,
have extensive experience in collaborative
efforts. Ultimately, the two will
collaborate with Ringel, a world leader in
high performance photovoltaic materials,
to integrate extremely thin films of these
promising ultra-efficient materials to a
variety of alternative substrates through
which ultra low-cost and highly efficient
solar energy conversion can be achieved
at high production rates.
Myers and Rajan also are among faculty
members whose work is central to the $48
million state-, industry- and cost share-
funded Wright Center for Photovoltaics
Innovation and Commercialization,
which enables collaboration with the
solar industry at large-scale and start-up
levels.
“Solar energy by photovoltaics,” Myers
says, “is one of the strongest technologies
for renewable energy. Since photovoltaics
contain no moving parts, have low
maintenance costs, and are based on
solid-state materials, they can last
indefinitely.”

New Cluster Tool for Combined Diamond and Nitride Crystal Growth
A team of OSU researchers has won a
National Science Foundation award for
the acquisition of a hybrid crystal growth
tool for synthesis of both electrical quality
diamond and III-Nitride semiconductors.
The team of researchers spans two
colleges and three departments including
Physics (Prof. Johnston-Halperin, CME,
principal investigator on the proposal;
Prof. Fengyuan Yang, CME; Prof. Harris
Kagan, HEPX), Electrical and Computer
Engineering (Prof. Siddharth Rajan; Prof.
Stephen Ringel) and Materials Science and
Engineering (Prof. Roberto Myers). This
cluster tool will allow for in situ sample
transfer of substrates between diamond
and nitride growth chambers, giving
it the unique capability to grow high
quality wide-bandgap semiconducting
heterostructures. Diamond exhibits
world record hardness and thermal
conductivity and its large band gap
makes it favorable for certain electronic
applications. Recent developments in
synthesis of diamond by microwave
plasma chemical vapor deposition (CVD)
have resulted in artificial diamond with
engineered electronic properties useful
for a wide range of applications. Unlike
diamonds found in nature, grown at
high temperature and pressure over
eons, plasma CVD grown diamonds are
produced using a mixture of methane
and hydrogen plasma incident on a
heated substrate. If a diamond substrate
is used, a single crystal
diamond film is possible.
In addition to diamond
synthesis, the tool contains
a separate growth chamber
for growth of wide band
gap GaN using a molecular
beam of Ga atoms reacting
with ammonia (NH3) on
a heated substrate. These
systems will be used to
explore heterostructures
combining diamond and
nitride nanostructures.
This research activity will
support local, national, and international
collaborations including the Center
for Emergent Materials (CEM, an
NSF funded MRSEC at OSU), the
RD42 collaboration (located at CERN
in Geneva, Switzerland), the Wright
Center for Photovoltaic Innovation and
Commercialization (PVIC, a state of Ohio
funded research center at OSU) and the
Center for Affordable Nanoengineering
of Polymeric Biomedical Devices
(CMPND, an NSF funded NSEC at
OSU). Critical assistance in preparing the
proposal was provided by the Institute
for Materials Research at OSU.

Ferrous Induction Furnace Advances Foundry Studies
A 150 lb capacity ferrous
induction furnace
(Inductotherm 3000Hz
75kW) was installed
in the OSU Casting
Laboratory. This is
an exciting addition
to the facilities. The
furnace allows students to melt steel
and cast iron by reaching temperatures
as high as 1600ºC, a capability that has
been unavailable in the Lab. Steel and
cast iron account for more than 80%
of all metals that are cast; casting such
metals provides our students invaluable
experience and expands the research
capabilities of the MSE department.
Such a furnace is a basic component of a
well-rounded casting laboratory.
The funds were provided by private
entities including the Central Ohio
American Foundry Society (AFS)
Chapter, the Southwestern Ohio AFS
Chapter, the Wisconsin AFS Chapter,
Installed and working well in the Casting Lab, an Inductotherm 3000Hz 75kW furnace.

Modeling Microstructure Evolution During Phase Transformation and Deformation
Phase transformation and deformation
in structural materials involve coupled
mechano-chemical processes, which
impose a difficult challenge to existing
simulation methods. At the Center for
Accelerated Maturation of Materials
(CAMM) new modeling techniques
and capabilities have been developed
to address these issues.[1] For the
first time, modelers are able to 1)
utilize directly ab initio calculations
in modeling dislocation transmission
across heterophase-interfaces; 2) capture
atomistic processes at diffusional time
scales[2] (Fig. A); 3) find critical nucleus
in solid-sate transformations and
deformation processes[3]; and 4) simulate
highly anisotropic microstructures
with strong spatial variation and
correlation (e.g., variant selection and
micro-texturing as shown in Fig. B), with
full incorporation of crystallography and
interfacial dislocation structures.
Advanced materials for structural
applications are known to exhibit
pronounced anisotropic properties
due to the presence of various
microstructural heterogeneities and
the inherent anisotropy of deformation
mechanisms. Current modeling
approaches utilize highly simplistic
descriptors of the microstructure that are
empirically correlated to the properties.
Such an approach is utterly inadequate
for addressing design needs. The new
modeling capabilities being developed

at CAMM will allow for building a
quantitative understanding of the
microstructure-property relationships.
Robust constitutive laws are likewise
being developed that capture the
effects of heterogeneous distribution of
various microtructural features on the
macroscopic behavior while minimizing
much of the effort that is currently
required for applying an existing alloy for
new applications as well as for developing
new alloy systems.

will be used for teaching and research.
Current research sponsored by AFS,
Ashland, Caterpillar, Cummins, Rio
Tinto and Tupi (Brazil) addresses the
problem of casting skin formation,
effects, and prevention in compacted
graphite iron castings. This material has
found increased usage in the automotive
industry, as it is the only alloy that satisfies
the increased pressure and temperature
requirements of the motor blocks for the
new high mileage diesel engines.
The members of the MSE AFS Student

availability of this new equipment and
they have already planned a number
of projects that will put the induction
furnace to good use.

A Micro-sized Caterpillar with Nano-sized Hairs
Titanium alloy debris, prepared by
mechanical filing, were oxidized to
produce TiO2 nanohairs on the surface
of the filing. The size of the debris
was approximately 100 µm having a
wavy surface that mimics the shape of
a caterpillar without any hairs. TiO2
nanohairs were grown on the surface
of the alloy debris by heat treating at
700°C under a limited supply of oxygen
(flowing Ar with 500 ppm of oxygen).
The length of the oxide nanohairs is in
the range of 1 and 2 µm and the diameter
ranges from 30 to 70 nm (see inset in
image above). With these nanohairs, the
debris resembles the shape of a caterpillar
with hairs. The oxide nanohairs were
identified as the TiO2 rutile phase by
electron microscopy. These nanohairs
have potential applications in sensors,
electronics and optoelectronics,
photocatalysis, and biomedical devices.

Research on Materials Aspects of Sliding Friction and Wear
It is now well known that materials in sliding contact exhibit dramatic changes in
structure and chemical composition adjacent to the sliding interface. These changes
influence the evolution of both friction and wear as sliding proceeds. Sliding tests,
combined with an array of complementary characterization techniques (XRD, OM,
SEM, EDS, AES, FIB, TEM, Microhardness, Kelvin probe, etc.), have demonstrated
the involvement of severe plastic deformation and mechanical mixing leading to the
formation of nanocrystalline or amorphous tribomaterial. The results depend on the
materials, the environment, sliding velocity, temperature, and other sliding conditions.
Typical sliding wear debris particles have the same structure and composition as the
tribomaterial.
In recent years, Prof. Rigney’s research group has combined experimental work with
2-D and 3-D molecular dynamics (MD) simulations. An example, from the work of
S. Karthikeyan, is shown in Figure 1. MD simulations help to explain effects of relative
hardness, crystal orientation and defect content. They also suggest that the interacting
materials flow like a fluid, complete with development of vorticity associated with
Kelvin-Helmholtz instability. The presence of vorticity accounts for mechanical
mixing, composition profiles and the disappearance of markers near the interface.
Vorticity also contributes to amorphization and the formation of nanocrystals.
This work has revealed much about the dynamic processes contributing to sliding
behavior. Development of a predictive model for sliding wear remains elusive. It will
undoubtedly require incorporation of the fracture characteristics of the tribomaterial
produced by sliding.

This uses a right-hand coordinate system with x to the right and y pointing toward the top of this page. The presence of the grain boundary in the Cu crystal strongly influences the development of deformation and structure during sliding. (b.) Nanocrystalline structure produced by sliding for the initial configuration shown in (a.). All of the following are involved: propagation of shear bands, formation of epitaxial Cu on Fe and dynamic recrystallization. Ref.: Karthikeyan et al., Wear 267(2009)1166.

25 Years of Service
In September, Geoff Hulse and David Jones were recognized by the College
of Engineering for twenty-five years of
service to The Ohio State University. Both
Geoff and Dave joined the University
in 1984, with Dave hired as part of a
VAX System Support Group and Geoff
hired to oversee the VAX support staff
housed in Chemical Engineering. They
maintained a large VAX 11/780 “mini”
computer which was the size of two home
refrigerators and was many times slower
than present-day desktops. Geoff and
Dave have overseen a great deal of change
since those days and, along with Mike Davis (who began working for them as
a student employee), have developed the
computing infrastructure that supports
the research and academic efforts of both
the MSE and Chemical and Biomolecular
Engineering departments.
Dave, following an interest in
programming, switched from Physics to
Computer Science as his college major.
In the early 1990’s, he was part of a
networking group at the university that
developed the directory system used by
OSU’s central e-mail system. Helping
the university improve the quality of its
data during this period was an important
accomplishment for the group and has
been of great benefit in the subsequent
years.
Geoff was instrumental in bringing
together the (then) three departments—
Ceramic, Metallurgical, and Chemical
Engineering—to purchase computing
resources for the departments’ academic
and research pursuits. Beyond his
computing expertise, Geoff ’s talents
as both a photographer and graphic
designer have likewise been a tremendous
asset to the departments. One impressive
example of his work was the multimedia
presentation he developed for the
Chemical Engineering department’s
Centennial Celebration.
Both departments wish to thank Geoff
and Dave for their many years of
service to the university!

MSE Grad Studies Minneapolis Bridge Collapse
The eight-lane I-35W highway bridge in Minneapolis, MN collapsed at about 6:05
PM CDT on August 1, 2007. NTSB investigators identified the U10W truss node was
a likely failure initiation site for the collapse[1, 2]. A finite element modeling group team
was formed from persons
in NTSB, FHWA, SUNY,
and SIMULIA Central to
study in detail the stress and
strain in the gusset plates of
the U10W joints. Min Li at
SIMULIA Central was a key
member of the modeling
group team. Working with
the team, Min created
the detailed U10W local
finite element model using
many nonlinear modeling
capabilities in Abaqus/
Standard, embedded the
local model into the FHWA
structural bridge model,
performed most of the detailed finite element analyses, and wrote much of the report[2].
The figure above is one example of the analysis results[1]. Based on the results from
the Abaqus model and other investigations, one of the conclusions from NTSB was:
“gusset plates at the U10 nodes, where the collapse initiated, had inadequate capacity
for the expected loads on the structure, even in the original as-designed condition.”[1]
Min graduated in 2006 with a Ph.D. degree in Materials
Science and Engineering. During her study at the Department
of Materials Science and Engineering, she took courses such
as Finite Element Method, Plasticity, Mechanical Behavior of
Materials, and Fracture Mechanics. She modeled the constitutive
behavior of magnesium AZ31B sheet with strong basal texture
and implemented the model into Abaqus/Standard using
UMAT routine. These courses and research work prepared Min
to conduct the stress analysis for the bridge collapse.

Welding Engineering-MSE Realignment
The MSE and Welding Engineering
faculties have voted unanimously to bring
the Welding faculty, staff, students, and
programs to MSE. As of the beginning of
Autumn Quarter, the realignment action
has been endorsed by the Interim Dean
of Engineering, Dr. Gregory Washington,
and by a vote of the College Faculty. We
await votes by the University Senate and
the Board of Trustees and approval by
the Office of Academic Affairs, all of
which may occur by the end of the 2009
calendar year.
The realignment will bring five regular
faculty, three staff, 95 undergraduates, 50
graduate students, associated degree and
research programs, and many dedicated
Welding Engineering alumni from
around the world to MSE. Resources to
hire three new faculty are also associated
with the realignment. The department
will still be known as Materials Science
and Engineering but will house both
the Welding Engineering and Materials
Science and Engineering degree
programs. The realigned department will
include the MSE office and lab space in
the Watts-MacQuigg-Fontana complex
and the Welding Engineering space at
the Edison Joining Technology Center
on West Campus. This is a very exciting
opportunity for both programs and we
look forward to welcoming the Welding
Engineers to MSE through the course of
the upcoming year.

both at the high school and collegiate
level. He taught high school Physics
move marks the end of years of discussion
and aborted attempts to implement
semesters. The move was finally made
at the urging of the Governor Strickland
and Chancellor Fingerhut, who seek to
align academic calendars at institutions
across the Ohio University System. While
the implementation date may seem far
off, the MSE faculty is well along in its
efforts to revise the MSE graduate and
undergraduate curricula. Draft curricula
will be posted on the MSE website later
this fall with a request for comment
from our students, alums, and external
advisory committee.

Humpty Dumpty, MSE-style
How do you protect a raw egg from a six story drop without
slowing it down? Students in Assoc. Prof. Kathy Flores’ “MSE 361:
Introduction to the Mechanical Behavior of Materials” were assigned
this task as their final project in Spring ‘09. The project requires
that the students consider how material deformation can dissipate
the energy of an impact, similar to a bicycle helmet or armor
plate. Parachutes, wings, or other means of intentionally slowing
the descent of the egg are not allowed. To further discourage
unintentional “floaters”, the eggs also need to hit a specified target
area.
A team-building exercise--as
well as a creative application
of classroom concepts--the
course fielded eight groups
of five students. Each group worked to design, construct,
test, and analyze the performance of their protective
egg-carrying devices. In order to prove that they had
optimized their designs, the teams each constructed
and demonstrated two protective devices: one designed
to protect the egg, and one with just enough protective
material removed to allow the egg to break. A portion of
the group’s grade depended on minimizing the weight
difference between the “pass” and “fail” designs. Most
groups took a highly empirical approach to their designs, developing and testing several
prototypes with drops from varying levels of the Arps parking garage.
The official “Drop Day” was June 4, 2009, when the students demonstrated their devices
with drops from the 6th floor of MacQuigg Labs onto the patio below. Members of the wider
MSE community, including several graduate students and faculty members, gathered in the
patio to hear students describe their designs and to cheer on the demonstrations. This year’s
solutions ranged from encasing the egg in bread slices in a peanut butter jar, to suspending
the egg in a flour-and-water mixture in an aluminum can placed in a coffee can filled with
water with a brick on the bottom. The MSE 361 Egg Drop 2009 highlights can be found on
the Department’s YouTube channel: http://www.youtube.com/osumaterials.

expand the materials science curriculum
tools suitable for high schools. The grant
will enable the development of a new
pilot program which provides materials
science “starter kits” of lab equipment
and curricular tools to Ohio high school
teachers who have been trained by ASM
through its Materials Camp program.
This pilot program will allow ASM to
prepare and launch a stand-alone high
school-level materials course. The grant
includes OSLN designation of ASM as a
“preferred provider” of materials science
professional development training for
teachers and schools offering courses.
The Department of Materials Science
and Engineering at Ohio State will play a
key leadership role in forming a network
of high school teachers and schools in
Central Ohio focused on offering high
quality materials courses. Prof. Glenn Daehn, the Mars G. Fontana Professor
of Metallurgical Engineering at OSU will
help launch the network.
“We are thrilled to be recognized by
OSLN and Battelle, who are the leaders
in Ohio STEM education innovations,
working with a consortium of
government, education, and industry
leaders,” said ASM Foundation Board
Chair, Dr. Raymond Decker. “Our
partnership with Ohio State materials
science and engineering faculty has
proven very productive.”
“For organizations such as Battelle,
the importance of investing in the
education of tomorrow’s scientists can
not be overestimated,” said Richard
Rosen, Battelle’s corporate vice president
for education and philanthropy
partnerships.
The ASM Materials Education
Foundation is located in Geauga County,
Ohio, and is the charitable educational
outreach arm of ASM International,
a non-profit, individual membership
organization representing 35,000 global
members who are scientists, engineers,
and technical experts working in

Engineering Service Learning at OSUby Elvin Beach, PhD ‘09
In the spring of 2008, I had the opportunity to travel
with a group of engineering students to Montana de
Luz, an orphanage for children living with HIV, in
south-central Honduras. The orphanage is built on
a hill overlooking the surrounding valleys filled with
sugar cane and two small villages.
Montana de Luz (MdL) houses between 30 and 40 children
and provides a nurturing environment, education, and medical
treatment for all of the children living there. It has continued
to expand during the past five years and adapt to the needs of
both the young and adolescent children living there.
A group of engineering students led by Prof. John
Merrill from the College of Engineering has been
venturing to MdL during spring break for several
years. During the winter quarter at OSU, projects
are identified with the director and on-site staff of
MdL that are implemented by teams of 3-4 students
per project during the trip. Our group addressed
several needs at MdL. Drinking water quality,
specifically high levels of arsenic in the water, was
measured and shown to be almost completely
removed with a three stage filtration system that
also reduced yearly filter replacement costs by several hundred
dollars. Water quality for one of the villages located in the
valley below MdL was also assessed and an improved chlorine
delivery system was designed, built and installed on site to
improve drinking water quality in the village where several of
the people who work at MdL live.
Another group, led by Gabe Moulton from the Office
of Information Technology, set-up a computer lab with
computers and monitors donated from various computer
labs around OSU. The computer team also provided a cost
effective solution for satellite-based internet access to the
remote location where the orphanage is located. Other projects
included construction of a rainwater collection system to help
grow vegetables in the gardens, insect and snake-proofing the
few on-site air conditioning units (seriously there were snakes
in them), and building some durable soccer goals for the
annual MdL soccer tournament. No matter the job, the kids
were always enthusiastic to help and even more excited when
3:00 play-time came around.
The trip was very rewarding and fulfilling from the standpoint
of making some improvements around the complex, but even
more so just for the chance to meet and spend time with the
kids. Overall this was a great opportunity to meet new people,
travel to a new country all while making a contribution to
an organization which makes a huge difference in these kids’
lives.
There are plenty of opportunities of this nature at OSU.
The Engineers for Community Service (ecos.osu.edu) is a
student run organization that works both locally and
internationally and is a good place to start looking
to get involved. If anyone is interested to learn more
about Montana de Luz, please visit their web-site
(www.montanadeluz.org).
As an aside, another student in MSE, Devin Braun,
a Junior in the program, also took part in the MdL
work. His focus was primarily on water-related
projects. Devin volunteered during Spring Break 2009
and offers his thoughts about the experiences on the
MSE department’s blog. Be sure to read his May 7,
2009 entry found at osumaterials.wordpress.com.
