Researchers have recently developed a method by which different crystals can be separated by their density in a magnetic field. They have now demonstrated the extraordinary efficiency of separation through 'magnetic levitation'.
A team of researchers from Uppsala University in Sweden has designed a microplasma source capable of exciting matter in a controlled, efficient way. This miniature device may find use in a wide range of applications in harsh environments, but can also help revolutionize archaeology.
North Carolina State University researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar energy devices and reduce the cost of solar energy production. The new connections can allow these cells to operate at solar concentrations of 70,000 suns worth of energy without losing much voltage as 'wasted energy' or heat.
It is control that turns scientific knowledge into useful technology - control over aerodynamic processes allows a pilot to land an aircraft, and control over the structure of atomic layers on a silicon wafer underpins semiconductor engineering.
Research has taken an important step towards standardising important electrical parameters of graphene such as surface potential and work function. The nascent graphene industry requires these standardised measurements so that the properties of graphene are understood well enough for it to be widely used in commercial electronic devices.
One of the major hurdles in the development of faster electronic devices is the amount of heat produced by silicon microchips. This heat is created by the transport of electrical charges through transistors. Researchers have now proposed a device that instead of moving electrons is able to transport information using electron spin over long distances.
