Magnetic molecular films are getting hot

Magnetism in a molecular thin film traditionally used in plastic electronics survives at temperatures reaching up to 100K, an order of magnitude higher than in previously studied molecular materials.

Probing wave functions in complex oxides with X-rays

Scientists describe the results of their theoretical study of the extent to which it is possible to extract information on the wave function of complex oxides using resonant X-ray techniques. The specific oxides considered by the team are those subject to strong spin-orbit coupling.

Nanotechnology e-whiskers as tactile sensors for robotics

From the world of nanotechnology we've gotten electronic skin, or e-skin, and electronic eye implants or e-eyes. Now we're on the verge of electronic whiskers. Researchers with Berkeley Lab and the University of California (UC) Berkeley have created tactile sensors from composite films of carbon nanotubes and silver nanoparticles similar to the highly sensitive whiskers of cats and rats.

Pushing the thermal limits of nanoscale SQUIDs

Researchers have introduced a new type of nanoscale SQUID based on optimised proximity effect bilayers. This consists of a noble metal (Au) layer as a thermal shunt which is integrated with a variable-thickness superconducting (Ti) layer. The noble metal layer helps control the superconducting transition temperature and the degree of heating in the device via the so-called superconducting proximity effect.

Frozen magnetic monopoles create new laboratory physics

Many of the most interesting things in nature are transient, or far-from-equilibrium. To discover the secrets of far from equilibrium states, physicists need simple yet appealing laboratory systems. Now, researchers have created just such a system in the magnetic material known as 'spin ice'.

Nanotechnology tools: DNA clamp to grab cancer before it develops

As part of an international research project, a team of researchers has developed a DNA clamp that can detect mutations at the DNA level with greater efficiency than methods currently in use. Their work could facilitate rapid screening of those diseases that have a genetic basis, such as cancer, and provide new tools for more advanced nanotechnology.
