System Bits: Oct. 9


Bringing plasmonic color to solid materials Researchers at the University of California, Riverside, used silver nanoparticles (AgNPs) to produce plasmonic color-switchable films for solid materials. This effect was previously achieved only in liquids. Rapid and reversible tuning of plasmonic color in solid films, a challenge until now, holds great promise for a number of applications,” sa... » read more

Power/Performance Bits: July 18


Ad hoc "cache hierarchies" Researchers at MIT and Carnegie Mellon University designed a system that reallocates cache access on the fly, to create new "cache hierarchies" tailored to the needs of particular programs. Dubbed Jenga, the system distinguishes between the physical locations of the separate memory banks that make up the shared cache. For each core, Jenga knows how long it would t... » read more

Power/Performance Bits: April 25


Thermal diode Engineers at the University of Nebraska-Lincoln developed a nano-thermal-mechanical device, or thermal diode, which uses heat as an alternative energy source that would allow computing at ultra-high temperatures. "If you think about it, whatever you do with electricity you should (also) be able to do with heat, because they are similar in many ways," said Sidy Ndao, assistan... » read more
