Controlling heat flow with atomic-level precision

Through a combination of atomic-scale materials design and ultrafast measurements, researchers at the University of Illinois have revealed new insights about how heat flows across an interface between two materials.

Researchers make first all-optical nanowire switch

(Phys.org)—Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1's and 0's were represented by bursts of light, instead of electricity.

How smartphone tech could change behavior

Funneling a steady stream of diversions straight to your pocket, smartphones are often cast as the ultimate distractors. But a University of Michigan engineering professor sees potential for them to be something quite the ...

Team observes real-time charging of a lithium-air battery

One of the most promising new kinds of battery to power electric cars is called a lithium-air battery, which could store up to four times as much energy per pound as today's best lithium-ion batteries. But progress has been ...

Researchers explore elections and voting behaviour with physics

Statistical physics has began to inch itself into the territory of social and human sciences in the past decade. Vast and complex social networks have particularly gained popularity among physicists. Now they have also started ...

Paper-and-scissors technique rocks the nano world

Sometimes simplicity is best. Two Northwestern University researchers have discovered a remarkably easy way to make nanofluidic devices: using paper and scissors. And they can cut a device into any shape and size they want, ...
