World’s smallest magnet The University of Tokyo has developed what researchers claim is the world's smallest nano-magnet. The nano-size ferrite magnet consists of iron oxide. With the material, researches devised a 7.5nm structure with magnetic properties.

Etching superconducting materials Superconductors are devices that have zero electrical resistance, making them attractive for a range of applications. But superconductors must be cooled down to temperatures at or near absolute zero on the Kelvin scale to work. This, in turn, limits their applications. Absolute zero equates to −273.15° on the Celsius scale and −459.67° on the Fahrenheit ... » read more

Simplified superconducting circuits Computer chips with superconducting circuits, which means they have no electrical resistance, are said to be 50 to 100 times as energy-efficient as today’s technology. Superconducting chips are also said to have greater processing power: Superconducting circuits that use so-called Josephson junctions have been clocked at 770 gigahertz, or 500 times the spe... » read more
