CHEM281 lecture slides

1. Chemical Information
CHEM281 – 2012

2. 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

3. 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

4. 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.

5. 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

6. 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

7. Some ways you could
share 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

8. 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

9. 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

10. 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

11. 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…

12. … 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

13. 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!

(if we have it)
Who has cited whom

20. How would you…
cite an article?
 Authors
 Title of the paper
 Where it was published – Journal name
 Year published
 Volume
 Issue
 Page numbers

21. Analysis of a reference
Colak, A. T.; Colak, F.; Yesilel, O. Z.;
Buyukgungor, O.
Synthesis, spectroscopic, thermal, voltammetri
c studies and biological activity of crystalline
complexes of pyridine-2,6-dicarboxylic acid
and 8-hydroxyquinoline. J. Mol. Struct.
2009, 936 (1-3), 67-74.

22. Summing Up (1)
Chemistry Subject Guide  “How do I find?”
 Chemical data
 Journal articles
 Material Safety Data Sheets
 Citation guide (ACS)

23. 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
Read the Screen!
 Author field
 Refining document type to “Review” for review articles
