The databases and chemical search tools will remain in place over on that site. The following is a small selection of recent items about informatics, online science tools, …

Alchemist ChemWebA mixed bag this week in my Alchemist column on ChemWeb.com this week. First up, news that US$1 million is to be ploughed into biofuels research that could circumvent some of the serious environmental concerns associated with this renewable energy source.

In the world of pharmaceuticals we discover that there might be yet another string to the bow of aspirin-like drugs, this time in the fight against breast cancer. …

Water salvation, photo by David Bradley

In the realm of physical chemistry (or is it chemical physics?) there was almost theological interest in this week’s Alchemist. Having written about water glass and how low-temperature studies of aqueous phase changes are helping scientists to explain this anomalous and yet ubiquitous material it was a simple spellcheck-induced typo that drew the most interest from The Alchemist’s email newsletter readers.

Wave after wave (pardon the …

Earlier this year organic chemist Adam Azman contacted me to ask if there is a free or open source chemistry dictionary available for word processors. Well, a quick search revealed only paid-for dictionaries so he set about creating his own from scratch.

“It took me the better part of a month,” Azman told Chemspy, “but I’ve made my own and I want
it to be as open-source as possible. Chemspy Sciencebase is …

K4 crystal

Diamond is not unique! Nature’s missing crystal discovered! A crystal as beautiful as diamond! Those were the themes running through dozens of articles in the media about a discovery made by Japanese mathematician Toshi Sunada of Meiji University. The original press release proclaimed that he had discovered a theoretical crystal structure with the same symmetry properties as diamond but with handedness, or chirality, and that this knocked the …

Plasticine, Salt, and Melting Snow

Salt water ice freezing

Why do they grit the roads with rock salt in winter? What does the salt do to the water to reduce ice on the roads? Is this somehow related to how salt affects the boiling point of water? Keywords to search for: colligative properties, boiling, freezing, ions, solutions, solvent, Raoult’s law

Meanwhile, I’ll let Plasticine models from Ithaca and cheesy music explain:…
