New promising method to detect cocaine in biofluids
WASHINGTON, US: A new study on cocaine, details how it may permanently damage proteins in the body. According to scientists, the information, gleaned from laboratory tests, could be used to potentially detect the drug in biofluids for weeks or months – instead of days – after use. The findings, which appear in the ACS journal Chemical Research in Toxicology, could also help explain cocaine’s long-term health effects.

Scientists create large graphene with exceptional electrical properties
When it comes to the growth of graphene – an ultrathin, ultrastrong, all-carbon material – it is survival of the fittest, according to researchers at The University of Texas at Austin. The team used surface oxygen to grow centimetre-size single graphene crystals on copper. The crystals were about 10,000 times as large as the largest crystals from only four years ago. Very large single crystals have exceptional electrical properties.

Scientists provide details of interactions on the atomic scale
BERLIN, GERMANY: How exactly atoms and molecules in biochemical solutions or at solid-liquid interfaces do interact, is a question of great importance. A groundbreaking work by HZB-scientists provides a new tool, which enables scientists to get a “fingerprint” of the interactions on the atomic scale. In collaboration with the group of theoretical physicist Oliver Kuhn, University of Rostock these fingerprints can be interpreted and linked to specific chemical interactions, thus allowing direct insight in what happens in the former ‘black box.’
