More chemical wonders – Yet more chemical wonders fall under the gaze of The Alchemist this week. First up, spray on radiators coming to a home near you to help cut heating bills by a third while ethanol-imbibing bacteria offer an important clue to preventing biofuel pipeline cracks. In the analytical world a beetle that feasts on the dead offers volatile clues about time-since-death for forensic investigators, and porous compounds that can gulp down radioactive iodine emerge from Sandia National Laboratory. Chemistry, once again, gives advertisers materials to help beer drinkers. Finally, yet another award for a young Thai chemist.
