Stacking instead of mixing cools down the chips
Julich, Germany (SPX) Nov 25, 2015 -
The overheating of computer chips is a major obstacle to the development of faster and more efficient computers and mobile phones. One promising remedy for this problem could be a class of materials first discovered just a few years ago: topological insulators, which conduct electricity with less resistance and heat generation than conventional materials. Research on these materials is still in ...

'Shrinking bull's-eye' algorithm speeds up complex modeling from days to hours
Boston MA (SPX) Nov 25, 2015 -
To work with computational models is to work in a world of unknowns: Models that simulate complex physical processes - from Earth's changing climate to the performance of hypersonic combustion engines - are staggeringly complex, sometimes incorporating hundreds of parameters, each of which describes a piece of the larger process.
Parameters are often question marks within their models, the ...

Flexoelectricity is more than Moore
Barcelona, Spain (SPX) Nov 25, 2015 -
The information revolution is synonymous with the traditional quest to pack more chips and increase computing power. This quest is embodied by the famous "Moore's law", which predicts that the number of transistors per chip doubles every couple of years and has held true for a remarkably long time.
However, as Moore's law approaches its limit, a parallel quest is becoming increasingly impo ...

Puffed rice cereal compaction unveils new phenomenon in materials science
San Diego CA (SPX) Nov 25, 2015 -
There's more to the snap, crackle and pop of Rice Krispies than meets the ear. A recent study by San Diego State University civil engineering professor Julio Valdes used the breakfast cereal to discover a new phenomenon in materials science: highly porous, brittle materials can deform in different ways depending on compaction velocity. Put another way, the speed at which one crushes a tube full ...
