An article in Phys.org announced that the IUPAC (International Union of Pure and Applied Chemistry) voted at a meeting this past August to change the standard atomic weights of 19 elements. Because atomic weights are averages, the number depends upon the amount of the element which is available, as well as the techniques used to measure the weights. The proposed changes are said to be due to the availability of more precise measurements. The changes in weights of the 19 elements will be published next year in the journal Pure and Applied Chemistry.

The InChI Trust has four short videos about the use and importance of using InChI (International Chemical Identifiers) to represent chemical structures. InChIs convey more information than SMILES, including structural changes such as tautomerization(1), which can be useful in structural searching. InChI identifiers are produced by a computer program from a structural drawing, and vice versa. An InChI generator is available from RSC.

It’s Banned Books week! Did you know that The Golden Book of Chemistry Experiments, written for children in the 1960’s, was banned for being too accurate? Read more here: Banned Book Awareness
Celebrate Banned Books Week by reading a banned book. Just remember your safety glasses!

We realize that closing the chemistry library has been inconvenient for many of you, so I am pleased to announce that you will now be permitted to check out reference items which were located in the chemistry library for a period of 1 week. This is a temporary situation, which will be extended until we are able to relocate the items to their permanent location at the Library of Science and Medicine. You may request reference materials as you would any other book, selecting your desired pick up location. You will receive an e-mail when your item is ready to be picked up, and when you arrive at the library to check it out the circulation staff will charge it out to you for 7 days.
I hope this makes things a little easier for you. Please let me know if I can help you get the resources you need.

We have added the following resources to the online chemistry collection:
Wiley e-journal backfiles for Chemistry
- Bulletin des Societes Chimiques Belges
- Heteroatom chemistry
- Journal of computational chemistry
- Journal of Raman spectroscopy
- Journal of polymer science Part C. Polymer symposia
The Springer e-book collection for Chemistry and Material Science
Available from 2005 through 2013. One of the benefits of owning a Springer e-book collection is that Rutgers faculty and students can purchase a print copy of an e-book included in the collection for the very discounted price of $24.95.
