How to teach gold to tell left from right

Nanometer-sized gold particles consisting of only a few atoms can be used as catalysts for important chemical reactions. Noelia Barrab├ęs from the Institute of Materials Chemistry at TU Wien has been researching new methods ...

Scientists create new nanocomposite from gold and titanium oxide

Oxides of different metals often serve as photocatalysts in various systems such as air purification, reactions of water decomposition and even in the production of self-cleaning surfaces for glass and mirrors. The physical-chemical ...

Clusters of gold atoms form peculiar pyramidal shape

Freestanding clusters of 20 gold atoms take the shape of a pyramid, researchers have discovered. This is in contrast with most elements, which organize themselves by forming shells around one central atom. The team of researchers ...

Turning light energy into heat to fight disease

An emerging technology involving tiny particles that absorb light and turn it into localized heat sources shows great promise in several fields, including medicine. For example, photothermal therapy, a new type of cancer ...

Applying precious metal catalysts economically

Researchers at Ruhr-Universit├Ąt Bochum and the Fritz Haber Institute Berlin have developed a new method of to conserve rare and expensive catalysts and use them sparingly. They enclosed a precious metal salt in tiny micelles, ...
