Porous boron absorbing

Researchers in Europe have developed a hydrogen storage material based on porous magnesium borohydride that can safely adsorb large quantities of the gas via both a physical and a chemical mechanism. They used X-ray diffraction, infra-red and Raman spectroscopy to …

Rocky road to confusion

Raman spectroscopy has become an increasingly useful tool in the geosciences partly because it is non-destructive and requires minimal sample preparation, but also because it can be carried out on site with various irreplaceable geological samples. Unfortunately, Raman can confuse, …

Chemical hits from Slinn Pickings

Space ice goes against the grain – Space ice made from a mixture of methanol and water expands under pressure, and shrinks when heated – the opposite behaviour to most solids. Dominic Fortes at University College London, UK, is interested …

Hydrogen storage, red wine, forensics

Crystal clear hydrogen storage – Solid materials rich in hydrogen, such as ammonia borane could help solve the gas storage problem for vehicle fuel cells. Now, a crystal structure of an alternative material, DADB, offers new hope of a stable …

A New Look at Neopentane's Chirality

The absolute configuration of a subtly chiral molecule has been determined using Raman optical activity and quantum mechanics. Werner Hug and his colleagues at the University of Fribourg, Switzerland, obtained the configuration of (R)-[2H1, 2H2, 2H3]-neopentane a molecule in which …

MEMS and implantable chips

Silicon chips and microelectromechanical systems (MEMS) that can be implanted in the human body will only be possible with a clearer understanding of the interactions between single-crystal silicon and human tissues and fluids, for example, formation of mineral apatite. This …
