Shortest carbon-chlorine single bond detected until now
The description of compounds and interactions between atoms is one of the basic objectives of chemistry. Admittedly, chemical bonding models, which describe these properties very well, already exist. However, any deviation from the normal factors may lead to improving the models further. Chemists with Professor Thomas M. Klapötke at [...]

Nanoneedle is small in size, but huge in applications
Posted on 29. Apr, 2009 by admin.
CHAMPAIGN, Ill. — Researchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. In addition to ferrying tiny amounts of cargo, the nanoneedle can also be used as an electrochemical probe and as an optical biosensor.
“Nanoneedle-based [...]
