Oscillating nanophase magnetite controls ice nucleation

Researchers report that magnetite nanoparticles, which are mechanically rotated by external oscillating magnetic fields, could disturb the water/crystal interface and promote supercooling during the freezing process.

Functional films made of environmentally friendly clay minerals and dyes

Transparent hybrid film that changes color with humidity via a novel mechanism.

New device could increase battery life of electronics by a hundred-fold

A group of physicists has developed a magnetic material that employs a unique structure - a honeycomb lattice that exhibits distinctive electronic properties.

Researchers control the properties of graphene transistors using pressure

Researchers have developed a technique to manipulate the electrical conductivity of graphene with compression, bringing the material one step closer to being a viable semiconductor for use in today's electronic devices.

An electronic rescue dog

Scientists have developed small and extremely sensitive gas sensors for acetone, ammonia, and isoprene - all metabolic products that we emit in low concentrations via our breath or skin. They combined these sensors in a device with two commercial sensors for CO2 and moisture.

Tiny shapeshifters

Chemists embark on a project to ultimately produce devices that operate mechanically on direct exposure to light.
