Heterophase nanostructures contributing to efficient catalysis

Selective catalysis plays a key role in various applications, such as the chemical industry and oil refining, hence, developing catalysts with high efficiency and excellent chemoselectivity has become a research hotspot. ...

Atomic fractals in metallic glasses

Metallic glasses are very strong and elastic materials that appear with the naked eye to be identical to stainless steel. But metallic glasses differ from ordinary metals in that they are amorphous, lacking an orderly, crystalline ...

The best of two worlds: Solar hydrogen production breakthrough

Using a simple solar cell and a photo anode made of a metal oxide, HZB and TU Delft scientists have successfully stored nearly five percent of solar energy chemically in the form of hydrogen. This is a major feat as the ...

Local icosahedral order in metallic glasses

(Phys.org) —Metallic glasses are essentially a frozen, supercooled liquid. They are amorphous metals, often alloys, which are non-crystalline and therefore have a highly disordered atomic arrangement. They are true glasses ...

Scientists reveal structure of a supercooled liquid

If a liquid metal alloy is cooled slowly it will eventually form a solid phase. Before it solidifies, however, the liquid undergoes a liquid-liquid transition to a phase in which it has the same concentration but a more ...

Study reveals ordinary glass's extraordinary properties

Researchers at the universities of Chicago and Wisconsin-Madison raise the possibility of designing ultrastable glasses at the molecular level via a vapor-deposition process. Ultrastable glasses could find potential applications ...
