Clay key to high-temperature supercapacitors

Clay, an abundant and cheap natural material, is a key ingredient in a supercapacitor that can operate at very high temperatures, according to Rice University researchers who have developed such a device.

Magnetic materials: Forging ahead with a back-to-basics approach

Scientists have recently started to explore the possibility of using an intrinsic property of the electron known as spin for processing and storing information. Magnetic fields can influence the dynamics of electron spin, ...

Size matters as nanocrystals go through phases

(Phys.org) —Understanding what happens to a material as it undergoes phase transformations – changes from a solid to a liquid to a gas or a plasma – is of fundamental scientific interest and critical for optimizing ...

Fukushima water handling 'sloppy': nuclear watchdog

Nuclear watchdog inspectors who toured Japan's crippled Fukushima plant following the discovery of a huge radioactive leak declared Friday that water storage at the site was "sloppy".

3D graphene: Solar cells' new platinum?

One of the most promising types of solar cells has a few drawbacks. A scientist at Michigan Technological University may have overcome one of them.

Designing and building nanocomponents to spec

Hybrid, multifunctional nanostructures with diverse 3D shapes and complex material composition can now be manufactured with a precise and efficient fabrication technique.

Magnetisation controlled at picosecond intervals

A terahertz laser developed at the Paul Scherrer Institute makes it possible to control a material's magnetisation at a timescale of picoseconds. In their experiment, the researchers shone extremely short light pulses from ...
