System Bits: Jan. 26

Precisely controlling graphene molecules Researchers at UCLA’s California NanoSystems Institute have found that in the same way gardeners may use sheets of plastic with strategically placed holes to allow plants to grow but keep weeds from taking root, the same basic approach can be applied in terms of placing molecules in the specific patterns they need within tiny nanoelectronic devices, w... » read more

Power/Performance Bits: April 21

Harvesting more electromagnetic energy Researchers from the University of Waterloo in Canada showed for the first time that it's possible to collect essentially all of the electromagnetic energy that falls onto a surface. Their approach involves the use of metamaterials that can be tailored to produce media that neither reflects nor transmits any power, enabling full absorption of incident w... » read more
