Updated: 2011-07-28 20:01:56Digging back into ACS journals this week, I came across this warning in a 1976 Journal of Chemical Education paper (DOI: 10.1021/ed049p583) that discussed preparing perbromate by bubbling fluorine gas through an alkaline bromate solution: There are problems associated with this preparative method for which precautions must be taken (8). For example, some fluorine escapes [...]Chemistry Central at the IUPAC 2011 Congress

Like most mines in the district, the Hidee is located at an auriferous pyrite deposit which is characterized by oxidized ore near the surface and a pyritic sulfide composition [...]This week on Chemistry World

What if the whole of the Periodic Table were all rocks and metal? And what if it were created in 1987 by Jesus, he of the Roadside as a tribute to Guns ‘n Roses? It is obviously a concept whose time has come, because there are several others around that attempt to knock out the [...]Periodic table of rock and metal is a post from: Sciencebase Science Blog
Chemistry in its element – calcium carbonate

Updated: 2011-07-21 02:40:46We ran our first experiments in the reaction calorimeter today. They were very elementary, involving only the metering one reactant into another at constant reaction temperature. The results suggested strongly that the reactants were consumed promptly and that good control of temperature is obtained by adjustment of the feed rate. Halt the feed and Qr falls off promptly.

But, like the elk with a broken leg, if the grizzlies don’t get it, the winter surely will. According to reports, the firm was beset with poor management, superior competition, a paradigm shift in buying behavior, and a crummy overall economic picture.

The article describes efforts by archeologists to dig sites in an area southeast of Kabul soon to be razed by bulldozers in preparation for copper mining. So, I understand the part about saving the [...]Ways to be an entrepreneur
Updated: 2011-07-11 02:33:46I had a discussion with some professor friends recently about the subject of entrepreneurialism among chemists. I made my usual points about how people become captains of industry. Be more like an engineer. Preferably one with an MBA. Naturally, my professorly friends were unmoved. Having spent their entire careers in academia, they just didn’t know [...]Casey Anthony and Chloroform: How Does It Work?

Much of the country was all caught up in the Casey Anthony trial over the past few weeks as the testimony concluded and the verdict was announced (full disclosure: I was not at all caught up. I didn't even read any articles about the trial until after the verdict was announced). If you want background [...]
