Mathematical molecules
In Issue 4 we reported on an amazing molecule that could make Boolean logic decisions on its chemical inputs and produce an "on-off" light signal depending on whether or not the logic was being satisfied. Now, Prasanna 'AP' de Silva and Nathan McClenaghan at Queen's University Belfast have taken related molecular logic gates on the first step towards a true molecular computer by getting them to do mathematical addition.
A well-oiled chemical plant
Reactive Reports has reported on novel methods for turning raw hydrocarbons into useful materials previously (Issue 6), now an alliance of industry and academic scientists is hoping to make agricultural plants, and not petrochemical plants, the source of the ingredients for some plastics and other products.
What's that smell?
A new technique that can identify odours could help people avoid hazardous materials when they move into a new home or work environment.
Come up and see my etchings
A improved method of etching silicon developed by Jy Bhardwaj from Surface Technology Systems Ltd (STS), Newport, UK, could side-step some of the problems facing researchers trying to build miniature motors, gearboxes, and sensors and Micro-Electro-Mechanical Systems (MEMS), from silicon on a commercial scale.

Thoughts on the ACD/ P-31 NMR Database and Prediction Software Program
| |
P-31 NMR is an absolutely essential tool in modern phosphorus chemistry,
and it has aided countless investigations in this area. Numerous
applications of the technique are in practice. With the modern high
resolution instruments, peak separation of a few hundredths of a ppm can be
achieved for mixtures of phosphorus compounds. Even complex mixtures such as
extracts of biophosphates or biophosphonates give well-resolved spectra.

If you are working on
a fascinating formulation or a marvellous material, or
perhaps you simply think your compound is simply cool,
then tell us about it and you could win a copy of the
fantastic ACD/ChemFolder!
First Prize is a copy of ACD/ChemFolder,
Second Prize is a copy of Commercial ChemSketch
including the DICTIONARY.
The runners-up prize will be an ACD/Labs t-shirt and baseball
cap.
So, get sketching and let's see those cool compounds. |
ACD/Labs proudly announced the winner of the first ACD/Labs
Scholar of the Year Award at the ACS meeting on 27th
March, in San Francisco.

There were plenty of
entries for the judges to wade through and with work presented
being of the highest scientific standard the final decision
was a difficult one to make. The three winners, in order,
were Györgyi
Kovács, Department of Medicinal Chemistry, University
of Szeged, Hungary, Valentine
P. Ananikov, ND Zelinsky Institute of Organic Chemistry,
Russian Academy of Sciences, and Oleh
Tanchak, the Department of Applied Chemical and Biological
Sciences, Ryerson Polytechnic University. Honourable mention
was given to Jiansuo Wang, Institute of Physical Chemistry
& College of Chemistry and Molecular Engineering, Peking
University. Reactive Reports extends a hearty congratulations
to all the winners!
The ACD/Labs Scholar of
the Year 2000 is already announced! |
