Updated: 2010-06-30 20:54:25the extent to which proteins bind metals thereby reducing the amount of free iond in solution detectable by titration is usually a function of their secondary (general three-dimensional form of local segments of proteins) and tertiary (its three-dimensional) structures. In protein denaturation, which can be caused by heat, secondary and tertiary structure is lost and the bound metal released into solution as indicated by the rise in mesure concentration.Homestake Mine Visit

The town of Lead, SD, pronounced “leed”, is home to the Homestake gold mine. The mine was purchased and subsequently developed by George Hearst, father of William Randolph Hearst, and partners ca 1876.

This week the US Environmental Protection Agency (EPA) announced the winners of the Presidential Green Chemistry Challenge Awards, which promote innovation and use of green chemistry for pollution prevention.
A couple of noteworthy winners include Dow and BASF, who were recognised for developing an environmentally friendly process for producing propylene oxide using hydrogen peroxide, and a [...]On the road

I just returned from a week-plus vacation to Ukraine, where I spent three days in the Chernobyl Exclusion Zone with three of the best folks one could ever hope to get stranded with in a radiological wasteland: Mike Coffey, Chad Treloar, and Edward Geist.

While the flight data recorder has not been recovered, 24 fault messages were relayed to the AF headquarters via satellite. From these messages, and from forensic evidence found floating [...]Industrial PGM Prices Flat

Rhenium has been flat at US$3000/lb since July of 2009 and osmium pricing has been flat for many years. This is based on the market pricing of these metals on the EIB.

We arrived at a Perkins restaurant to rustle up some grub this evening and had an encounter with reality television. The characters from the cable television show “Dog the Bounty Hunter” were filming inside the restaurant. Dog is actually named Duane Lee Chapman and has quite a colorful history. He was born in Denver, CO, in 1953. According [...]A bit of sympathy for BP
Updated: 2010-06-10 01:18:58I can’t help but have some sympathy for the folks at BP just now. They are not the evil empire and despite their poor safety history, say, the recent Texas City refinery explosion, they do in fact rack up a good many safe operating hours doing very hazardous work. They handle and process flammable materials [...]Puzzling polymorphs
Updated: 2010-06-08 05:47:44Polymorphism is a common and sorta crazy issue in pharmaceutical process chemistry. Basically put, a drug molecule in the solid state can have multiple crystal forms. Different impurity profiles and different crystallization techniques (solvents, heating/cooling rates) can produce different polymorphs, which can have wildly different physical properties and bioavailabilities. A famous story of troublesome polymorphism [...]Science as Art
