Chapter 1: INTRODUCTION

At the frontier of both scientific and engineering research, optics and

photonics stand as exceptional promises in the introduction of new breakthroughs.

Beneficial technologies, ranging from common fluorescent light bulbs to state-of-the-

art electronic devices, are results from the study of optics and photonics. Such

applications would never exist without the insight into the behavior of light.

Since 31 January 2008, Chulalongkorn University Student Chapter of SPIE

was founded, along with Chulalongkorn University Student Chapter of OSA, by a

group of students in the Nano Engineering program, International School of

Engineering (ISE), Faculty of Engineering, Chulalongkorn University. The mutual

ultimate goal of both chapters is to promote the study of optics and photonics among

fellow students, as well as local communities.

In 2013, Chulalongkorn University Student Chapter of SPIE has committed

itself to educating fellow students and local communities about the basic knowledge

and application of light, as well as the knowledge of nanotechnology. We have

raised a group of avid learners who are aware of the significance of this science,

appreciate how the phenomena of light are exploited, and are able to utilize the

technology suitably. Moreover, we initiate and support those with interests in

furthering their study as well.

Chapter 3: ACTIVITIES

3.1 SPIE WORKSHOP 2013: NANOTECHNOLOGY

5

3.1.1: Preparation

Rational:

Due to the declining number of applicants in nanoengineering program and the lack of motivation among students, as opposed to the expanding trend of the field of nanotechnology, Chulalongkorn University Student Chapter of SPIE found it deeply compelling to contribute a spark of inspiration to the community. We have found that

1. Nanotechnology industry in Thailand is still immature, not as marketable as other conventional fields of engineering

2. People in general have limited knowledge and awareness about nanotechnology.

3. Not many accomplishments from researchers and alumni have been widely publicized yet.

We see that our chapter has the capabilities and resources, and can contribute in the issue number two and three, leading to our project objectives.

11

NanoTalk Part1: Nanofabrication (9:00 – 11:30) The talk underlined the distinctions of fabrication techniques among macro-materials (the scale to which most participants can relate), micro-materials (the breakthrough leading to the world we are living in), and nano-materials. Our team tried to make the subject as easy to understand as possible by using common terms, clear comparisons (using movie scenes to explain processes) and joking about things widely talked in social network. In whole, we managed to keep all the main concepts in line so that participants could comprehend the differences of nanoworld. Moreover, we talked about the future impact in short, medium and long terms. With reliable supporting theories (e.g. Moore’s Law), we gave them inspiring ideas about the intrinsic potential and importance of nanotechnology.

Afterwards, we had a break. Drinks and snacks were organized, and distributed systematically. Participants were encouraged to write down their questions from the Nano-talk Part 1 on small pieces of paper we prepared for them, which were answered in Q&A session.

12

NanoTalk Part2: Behavior Changes of Nanomaterials (11:40 – 12:20) The talk focused on the changes in behaviors of materials of various sizes. We introduced a sense of how small one nanometer is, with examples and interesting facts. As we tried to relate to things taught in high school, we talked a lot on the forces, and the types that become important in nanoworld. Changes in optical properties according to size and shape were mentioned a lot, for they would have the background to further on in the afternoon experiment session.

Experiment Section (13.00 – 15.00)

Chulalongkorn University Student Chapter of SPIE received permission from Assoc. Prof. Dr. Sanong Ekgasit, Ph.D. from the Faculty of Science in adapting his research project about silver nanoparticle in this experiment section.

Students were divided into a group of 20 members. So there would be 3 groups in total assigned to different starting bases, and rotating every 30 minutes.

---------------

Station 1 Shape Transformation of Silver Nanoparticles

1.1) 1ml of 400ppm AgNS in starch system solution was filled in a flask 1.2) 1% H2O2 was gradually dropped by 1ml syringe in assigned number of drops,

each drop 0.05ml 1.3) The solution must be stirred vigorously after each drop 1.4) The solution was kept still for 30min to let the system settle 1.5) Then all flasks were gathered and compared

15

Station 2 Application of AgNPr: Hand Sanitizer and Spray

2.1) 110ml of distilled water and 40ml of 95% alcohol were mixed homogeneously in a 250ml beaker

2.2) 0.45g carbopol-940 was gradually sprayed while stirring until dissolved 2.3) 0.45g of Triethanolamine was filled in the beaker drop by drop while stirring.

The solution would gradually get thickened 2.4) Then 5ml of AgNPr is dissolved with the gel by stirring the mixture

homogeneously

Station 3 SEM Usage

In this station, participants had got to learn about Scanning Electron Microscope (SEM). Much contributions were from Dr. Werayuth Srituravanich, from MEMS Nanotechnology Lab, who had allowed SPIE Student Chapter Chulalongkorn University to use his standard tungsten-filament SEM for this project; and from Ms. Orawan Kannika, Dr. Werayuth’s graduate student, who helped supervise and educate participants about the usage of SEM.

Participants, in a group of 20, first learnt basic science behind SEM, and then learnt how to operate SEM by computer from Miss Orawan. They learnt how to control direction, magnification, resolution and contrast from hands-on experience. The samples were already prepared and placed inside SEM. They are silver nanoparticles with different morphologies: spheres, plates, and dendrites. These samples were provided by Prof. Sanong Ekgasit’s Lab.

17

Ms. Orawan Kannika, Dr. Werayuth’s graduate student, who helped supervise and educate participants about the usage of SEM

We received mostly positive appraisal from participants for it was a rare opportunity for them, even for undergraduate student, to learn about actual standard equipment used in real life such as SEM. They enjoy having little contests of finding the best picture of each specimen. However due to time limitation, not all participants had the opportunity to operate the equipment.

---------------

Experiment Explanation (15:00 – 15:40)

Silver nanosphere (AgNS) can be enlarged by H2O2 via the mechanism of cyclic oxidation-reduction. Most, but not all, of AgNS is oxidized into Ag+ by H2O2 as described by the following equation:

2Ag0 (s) + H2O2(aq) → 2Ag+

(aq) + 2OH-(aq) E0 = 0.068V

H2O2 also reduce Ag+ back into its solid form. However, the rest AgNS particles that

are not oxidized serves as seeds for reduction and Ostwald ripening process

Therefore AgNSs gradually enlarge and transform its shape into AgNPr as described by the following equation:

2Ag+(aq) + 2OH-

(aq) + H2O2(aq) → 2Ag0(s) + 2H2O(aq) + O2(g) E0 = 0.947V

Both reactions can occur spontaneously as indicated by the positive electric

potentials. As the shape transformation proceeded, the color of the solution changes

18

as well due to the red-shift of plasmonic mode. As the particle become larger and

more planar, the dominant In-Plane Dipole Plasmonic Resonance (IPDPR) intensity

increases along with the reduction of Dipole Plasmonic Resonance (DPR) intensity.

Therefore we can observe the change in color from yellow to red, pink, violet and

ultimately blue depending on the molar ratio between H2O2 and silver nanoparticles.

3.2 Visiting PTT-HR

23

PTT is a Thai state-owned SET-listed oil and gas company. PTT is one of the largest corporations in the country and also the only company from Thailand that listed in the Fortune Global 500 companies, which ranks 128 among top 500 companies in the world, an improvement of 27 ranks since 2010 according to Fortune magazine in 2011.

The main driving force of PTT from its origin comes from the Engineering Faculty of Chulalongkorn Univ. During their PR touring of the scholarship available for students at Chulalongkorn Univ, they took notice on our work, interested, as they did not have much idea about nanoengineering and our program. At first, they requested to attend the workshop; however the contents were prepared mainly for high school students who are interested in science. Eventually we came to an agreement that we had a presentation for PTT HR department at PTT headquarter.

The presentation was about two hours, including the Q&A session.

Kasinan, Thatchanon, and Chirakit (from left to right respectively) explained the concept of nanotechnology, and its role in energy sector to PTT HR

3.3 OSA Educational Outreach Collaboration

25

As one of the chapter commitments, an outreach program has been organized yearly since establishment. The outreach program aims to raise awareness of optics and science learning through participation by working directly with local grade school students in various types of event such as classroom demonstrations and science fairs. The key expectation of the program is to support and inspire the next generation to become optics and photonics leaders, as well as to provide additional resources to underserved communities.

The 6th outreach program organized by Chulalongkorn University Student Chapter of OSA was held on August, 5th 2013 under the title “OSA Youth Education 2013”. The objective of the program is to give the optics knowledge to the students and to encourage them to have an interest in light, not only now but in the future as well.

The program was held at “Banklongpramopisai School” in Nakornpathom which is a remote-area primary school. The school was of the interest to the chapter by the help from one of the member’s friend who had organized such an activity before, saying that the students were enthusiastic and willing to learn everything. Therefore, the program was initiated.

Grade school students learning optics through hand made 3D glasses.

26

There were a total of 70 participants in this event including 48 primary students, 18 Nano Engineering students, and 4 teachers. The first activity was to teach all of the students how to make 3-D glasses. Later, they were shown 3-D movies and explained how they function. It was a big fun even the teachers joined in!

Next, the students were divided into groups to do activities regarding the basic properties of light including reflection, refraction, light mixing, lens and magnification. During the activities, many problems were uncounted. Since the activities were related to light, the natural light from the surrounding was too bright for the students to have clear images of the activities, as in the case of light mixing activity. However, due to an unavailable enclosed room, an enclosed box was built to block the surrounding light.

At the end of the activities, the chapter gave thanks to the teacher for giving this invaluable opportunity and also a big hand to all the students who make this event a huge success. The chapter plans to do more of this activity in the future in order to spread more opportunity to children and to give more knowledge about optics to the communities.

3.4 SPIE Student Chapter Leadership Meeting at OPTICS + PHOTONICS 2013

Details of the activity:

Date: 22nd -29th September, 2013

Location: San Diego, CA, USA

28

Description of activity:

Chirakit Kwangsukstith, Kasinan Suthiwanich, and Thatchanont Jirasupangkul were

the representatives from our student chapter to present our accomplishment with

other student chapters. They were invited to participate in a set of student

workshops as well, one of which was SPIE Chapter Leadership Workshop. They

had an opportunity to learn about being pro-active leader in putting forth knowledge

into action for the benefit of the community. They also had chances to exchange

ideas and make connection with many international students from around the world.

“… and because of that, we got to meet many new people, sharing each of our

ideas. One of the most discussed topics was about organizing student chapter. And

we came back with lots of ideas to improve our chapter, and hopefully, you will hear

from us again in the near future!” said Chirakit, the current president of our chapter.

Although our chapter was one of a few undergraduate chapters, we receive many

good supporting responses from other chapters, which are mostly graduate

chapters. “We were intimidated,” reflected Kasinan, Vice President, “because most

chapters presented about their works, researches and papers. However we were

surprised to receive many interests from them. Many said that they wanted to do an

educational outreach, since it is good for the society.”

CHAPTER 5: FUTURE PLANS

After submitting this report (the first of February), Chulalongkorn University Student Chapter of SPIE will hold a final meeting of this year, to recruit members, elect officers, and discuss about the things we did in 2013.

Early talks suggest that the majority of current chapter members support the idea of making SPIE workshop (originated in 2013) an annual event. So it is very likely for SPIE workshop to continue to be a main event for next year.

However, with major changes in organization structure of the chapter, we hope to be able to attract more members, to create varieties of new events, and optimize the existing ones.

Another objective, which we still have to work on the details, is to make Chulalongkorn University Student Chapter of SPIE an information center about optics, and photonics. The idea is to try organizing an informal lecture with a professor from the department, periodically.
