Chemical InformationCHEM281 – 2012
We are aiming at…
Finding reliable (and recent) information sources
Finding a paper by specific authors
Finding review articles on particular subjects like biochemicals
Finding information for compounds –formulas, structures, toxicity
Finding out about enzymes – EC numbers
Using Google Scholar
Find out how often a paper has been cited
Formatting a bibliography in the ACS citation style
You already know(I expect)…
Journals have articles relating to the journal topic
A review article sums up other articles written on a subject
Citing = listing what you have read as research or background
References (in-text and at end) are used when the author is
Quoting; or
Referring to facts
Some may already know…
APA-style referencing
How to find papers
Google Scholar
Scopus
Lecturers’ papers department website
How to locate chemical data
Merck Index, etc.
But we need to know more about…
How to find reliable sources
Articles
References
Review articles
Chemical data, EC numbers etc.
Citation counts
How much has an article been cited?
How to reference properly
ACS citation style
Today we will look at…
1. How scientists share information
2. Finding chemical and/or enzyme data
3. Structure drawing (briefly)
4. Finding papers
5. Referencing sources in ACS style
Some ways you couldshare your results
Give talks
Write them down and send to a friend
Send letters or newsletters
Publish in newspapers
Publish independently – get in touch with a printing press to publish papers or books
Gather articles about the same subject and send out a journal
Journals
“Magazines” for scientists
Narrow subject focus
New issues without end, often regular(quarterly, monthly etc.)
Each issue has articles by a various authors about their research
How could hoaxes be prevented?
Repeat the experiment; same results?
Check the author’s credentials
Employ experts in the subject to edit journals
Check ideas against previously published information
Peer review by other experts
Peer review
Article sent to peers = scientists working in the same field
Peers review the article to check
Accuracy
Clarity
Reproducibility
Author makes corrections and improvements
Publication
Balancing access…
Put journals in a search engine
Easy to find
Big companies manage databases
Articles from many journals all in one place
Articles could be free to view…
… and profit
Charge institutions
Subscription fees or pay-per-article
Free preview, pay for the full article
Free to view, funded by:
advertising
research grants
donations
government
universities
Databases
By publisher vs by subject
Full-text vs citation only
Articles vs data
Precision vs usability
Pay-for vs free
No single one has it all!
hazard ratings
accidental release measures
handling and storage
toxicological data
properties
EC numbers
properties
reactions
substrates
organisms

Summing Up (1)
For reliable sources search in databases that collect peer-reviewed
journals
SciFinder, Web of Science, Scopus, Google Scholar
Specialist databases:
BRENDA for enzymes and EC numbers
ChemWatch for hazards and material safety data sheets (MSDS)
ChemSpider/ChemSketch for structure, properties, drawing molecules
