Metal alloys can fail unexpectedly in a wide range of applications---from jet engines to satellites to cell phones---and new research from the University of Michigan helps to explain why.

Do hyper-coordinate planar transition metal atoms exist?

harminka — Tue, 01 Jul 2008 07:11:58 -0500

A study reported in Vol 51, Issue 7 (July, 2008) of Science in China Series B: Chemistry has shown that wheel-shaped structures with octa- and enneacoordinate planar cobalt, iron and nickel centered in perfect octagonal and enneagonal boron rings, are stable on corresponding potential hyper-surfaces. This suggests that the central element bonding capacities have not been exhausted.

Lake sediments help scientists trace 7,000 years of mining, metal use in China

harminka — Mon, 16 Jun 2008 08:37:03 -0500

A new geochemical study illuminates 7,000 years of mining and metal use in central China and links these trends to fluctuations in airborne pollution during the Bronze Age and other military and industrial periods in Chinese history. The study, which could help scientists better assess the accumulative environmental effects of human activity in the region since prehistory times, is scheduled for the July 1 issue of the ACS' Environmental Science & Technology, a semi-monthly journal.
