A novel technique reliably tells left-handed from right-handed variant of a compound
05/24/2013 - 07:06

The chemistry of life is built on left-handed and right-handed molecules that can have completely different functions. A novel technique, developed by researchers from the US and Germany, can reliably tell these mirror molecules apart. The new method can in principle even detect these so-called enantiomers in mixtures of substances.

Using clay to grow bone
05/14/2013 - 12:32

In new research published online May 13, 2013 in Advanced Materials, researchers from Brigham and Women's Hospital (BWH) are the first to report that synthetic silicate nanoplatelets (also known as layered clay) can induce stem cells to become bone cells without the need of additional bone-inducing factors. Synthetic silicates are made up of simple or complex salts of silicic acids, and have been used extensively for various commercial and industrial applications, such as food additives, glass and ceramic filler materials, and anti-caking agents.

Researchers Propose New Old Way to Purify Carbon Nanotubes
05/01/2013 - 12:58

An old, somewhat passé, trick used to purify protein samples based on their affinity for water has found new fans at the National Institute of Standards and Technology (NIST), where materials scientists are using it to divvy up solutions of carbon nanotubes, separating the metallic nanotubes from semiconductors. They say it's a fast, easy and cheap way to produce high-purity samples of carbon nanotubes for use in nanoscale electronics and many other applications.
