Hi, November's MOTM is Tetrodotoxin, the potent nerve agent found in puffer fish. It has been written by Jim Johnson from a company called 3D Biochem in the US who make molecular models for schools & universities.

One-Wedge Convention for Stereochemical Representation, Proposal
by Shu-Kun Lin 22 Oct '99

22 Oct '99

Dear colleagues: We have prepared a proposal on "One-Wedge Convention for Stereochemical Representation" at http://www.mdpi.org/molecules/wedge/ This convention, if followed by all the chemists, will be very useful. Without a convention of graphic representation, the situation of stereochemistry representation is now very much similar to the nomenclature situation before the CIP rule of stereochemical nomenclature was proposed. Could you please take a look at the first draft of this proposal at the http://www.mdpi.org/molecules/wedge/ website? We would greatly appreciate it if you offer some suggestions. Any of your chemsists who improve it further will be invited to be coauthors.

"Chemoinformatics"
by Dr. Wendy A. Warr 14 Oct '99

14 Oct '99

Colleagues, I had agreed to summarize for these lists (excuse multiple postings) all the comments I received about cheminformatics/chemoinformatics/chemiiformatics etc. Actually I had decided that the easiest thing would be to refer you to my slides on the ACS COMP site, where you could also see the slides of other speakers in this ACS New Orleans symposium. Unfortunately there have been some problems in putting the slides onto the Web site. There is also a possibility that the symposium proceedings will appear in a book and it has been suggested that it would be inadvisable to put my results up on a Web site or a list for copyright reasons. However, I DO intend to put my talk into my usual (commercial) meeting report so I have to resolve the copyright issue soon. I just wanted to thank everyone who gave me their suggestions, and let you know that I have not forgotten about the requested summary.

RE: High level education at distance
by R.C.F.Jones＠open.ac.uk 07 Oct '99

07 Oct '99

Armel asks about higher-level course in chemistry taught at a distance. As the largest UK provider of distance education (approx 200,000 students registered in 1999), I should point out that the Open University (OU) does provide an MSc in Science as a taught masters course, with text, CD-ROM and WWW-based elements to the programme. Students must take 3 modules from those available, one of which is called Imaging and Molecules in Medicine (code S803), and is a joint chemistry/physics module. Details of the programe and of the individual modules, including S803, are to be found at the OU MSc website: http://www2.open.ac.uk/SciMsc/ ________________________________________ Professor R C F Jones (Professor of Organic Chemistry & Head of Department) Department of Chemistry The Open University Walton Hall Milton Keynes MK7 6AA, UK e-mail: R.C.F.Jones(a)open.ac.uk tel: +44 (0)1908 653199; fax: +44 (0)1908 858327 WWW page: http://www2.open.ac.uk/Chemistry/RCFJ.html ________________________________________ > ---------- > From: Armel Le Bail > Reply To: Armel Le Bail > Sent: 28 September 1999 9:52 am > To: chemweb(a)ic.ac.uk > Subject: High level education at distance > > The Web-based Birkbeck College advanced certificates > in crystallography are well known : > http://www.cryst.bbk.ac.uk/teaching.html > > It is a pleasure to add some competition with the SDPD > Internet Course (Structure Determination by Powder > Diffractometry) : > http://sdpd.univ-lemans.fr/course/ > > Chemistry has always something to do with crystal structures, > so, visit and apply to these high level Web-based courses ! > > I would be interested in hearing of other high level courses > offered in chemistry. > > Best > > > Armel Le Bail - Universite du Maine, Laboratoire des Fluorures, > CNRS ESA 6010, Av.
