Supercritical carbon dioxide: Forming formic acid

Date: Aug 15, 2012

Author: David Bradley

Carbon dioxide can be both starting material for the production of formic acid through hydrogenation and also the solvent for the reaction if held in the supercritical; the usual complexities of extraction of product from solvent essentially removed as the solvent can be evaporated by simply releasing the pressure from the system and trapping the carbon dioxide gas released. NMR spectroscopy allows the German inventors of the process to keep track of reactants and products.

NMR gets the needle: Bacterial target pinpointed

Date: Jun 1, 2012

Author: David Bradley

The structure of a "needle" used by various bacteria, among them strains that cause bubonic plague, enterohaemorrhagic colitis, typhoid fever, Shigella dysentery and cholera, to get into host cells has been obtained at atomic resolution using NMR and other techniques. The research could ultimately lead to the development of novel drug to combat these and other diseases.
