Butterfly inspires new nanotechnology

By mimicking microscopic structures in the wings of a butterfly, an international research team has developed a device smaller than the width of a human hair that could make optical communication faster and more secure.

Graphene provides efficient electronics cooling

A layer of graphene can reduce the working temperature in hotspots inside a processor by up to 25 percent – which can significantly extend the working life of computers and other electronics. An international group of researchers, ...

Less friction loss in combustion engines

Researchers have developed a method that can reduce engine friction and wear even during production of engine components. Special coatings can help to reduce fuel consumption and CO2 emissions.

Building 3-D fractals on a nano scale

It starts with one 3D structure with eight planes, an octahedron. This repeats itself to smaller octahedra: 625 after just four steps. At every corner of a new octahedron, a successive octahedron is formed. A truly fascinating ...

Dual-color lasers could lead to cheap and efficient LED lighting

(Phys.org) —A new semiconductor device capable of emitting two distinct colours has been created by a group of researchers in the US, potentially opening up the possibility of using light emitting diodes (LEDs) universally ...

Discovery of increase in magnetic moment at grain boundaries

The NIMS Structural Materials Unit, in joint research with a group at the Kumamoto University Graduate School of Science and Technology, experimentally measured the 3-D electronic state of pure iron and discovered a phenomenon ...

Computational physics moulds the future of electronic devices

Fundamental studies based on computational physics are an essential part of many different branches of research – from medical technology to mobile communication. Javad Hashemi has studied the electronic properties and ...
