Detailed insight into friction: How objects start to slide

Chemists and physicists at the University of Amsterdam shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how ...

Making mini-magnets that induce a quantum anomalous Hall effect

A new device has been fabricated that can demonstrate the quantum anomalous Hall effect, in which tiny, discrete voltage steps are generated by an external magnetic field. This work may enable extremely low-power electronics, ...

Simulating 3D-AFM images for systems not in equilibrium

Researchers at Kanazawa University report in the Journal of Physical Chemistry Letters how to simulate 3D atomic force microscopy images of out-of-equilibrium systems involving biomolecules. The approach makes use of a celebrated ...

A new fuel cell electrolyte

As far back as the 1930s, inventors have commercialized fuel cells as a versatile source of power. Now, researchers from Japan have highlighted the impressive chemistry of an essential component of an upcoming fuel cell technology.

Study paves the way for new photosensitive materials

Photocatalysts are useful materials, with a myriad of environmental and energy applications, including air purification, water treatment, self-cleaning surfaces, pollution-fighting paints and coatings, hydrogen production ...

Extreme UV laser shows generation of atmospheric pollutant

An advanced laser technique has allowed researchers to observe, in real-time, the decomposition of a pollutant into atmospheric nitrous acid, which plays a key role in the formation of ozone and photochemical smog. The technique, ...
