Why gold-palladium alloys are better than palladium for hydrogen storage

11-Jul-2018

Materials that absorb hydrogen are used for hydrogen storage and purification, thus serving as clean energy carriers. The best-known hydrogen absorber, palladium (Pd), can be improved by alloying with gold (Au). New research led by The University of Tokyo Institute of Industrial Science explains ...

Salt boosts creation of 2-D materials

23-Apr-2018

A dash of salt can simplify the creation of two-dimensional materials, and thanks to Rice University scientists, the reason is becoming clear. Boris Yakobson, a Rice professor of materials science and nanoengineering and of chemistry, was the go-to expert when a group of labs in Singapore, China, ...

The limits of friction

03-Apr-2018

Friction is created when two surfaces slide one on top of the other. Since this consumes additional energy, this so-called sliding friction is considered an irksome yet inevitable aspect of dynamic processes. However, to set a stationary object in motion, its static friction must be overcome ...

Boron can form a purely honeycomb, graphene-like 2-D structure

16-Mar-2018

Seeking for low-dimensional boron allotropes has attracted considerable interest in the past decades and tremendous theoretical works predict the existence of monolayer boron. As boron has only three valence electrons, the electron deficiency makes a honeycomb lattice of boron energetically ...

Two-dimensional melting of hard spheres experimentally unravelled after 60 years

First definitive experimental evidence of two-dimensional melting of hard spheres

25-Apr-2017

After extensive research, scientists from the Department of Chemistry at the University of Oxford have found experimental evidence that sheds new light on the melting of two-dimensional substances. Findings from the study could be used to support technological improvements to thin film materials ...
