IR spectroscopy detects that oxygen defects act as active centres

IR-Catalysis-sIn the chemical industry, heterogeneous catalysis is vital for the manufacture of basic or fine chemicals, in catalytic converters of exhaust gas and for the chemical storage of solar energy. A new infrared spectroscopy method can study processes at surfaces of oxides used as catalysts.

CD shows that proteins can refold in the absence of water

New research by scientists at the University of Bristol has challenged one of the key beliefs in chemistry: that proteins are dependent on water to survive and function. The team’s findings could eventually lead to the development of new industrial enzymes.

Pittcon 2012 attendance

The Pittcon organisers have released the attendance figures for Pittcon 2012. The headline overall attendance is down at 15,754, as was probably expected. These figures are always an excuse for much discussion amongst hardened Pittcon visitors. To me, the interesting point is the relative changes between conferees and exhibitors.

SERS may benefit from new, single-step method of fabricating microcapsules

A new, single-step method of fabricating microcapsules, which have potential commercial applications as a substrate for surface-enhanced Raman spectroscopy (SERS), and in industries including medicine, agriculture and diagnostics, has been developed by researchers at the University of Cambridge, UK. Their have been published in Science titled “One-Step Fabrication of Supramolecular Microcapsules from Microfluidic Droplets”.

Mass spectrometry detects nicotine in Mayan container

Archaeologists examining late period Mayan containers have identified nicotine traces from a codex-style flask, revealing the first physical evidence of tobacco use by ancient Mayans. The study published in Rapid Communications in Mass Spectrometry reveals the flask is marked with Mayan hieroglyphics reading, “y-otoot ’u-may” (“the home of its/his/her tobacco”), making it only the second case to confirm that the text on the exterior of a Mayan vessel corresponds to its ancient use.
