Power/Performance Bits: Jan. 31


Microbial nanowires Microbiologists at the University of Massachusetts Amherst report that they have discovered a new type of microbial nanowire, the protein filaments that bacteria use to make electrical connections with other microbes or minerals. The team was motivated by the potential for improved "green" conducting materials for electronics. According to Derek Lovley, professor of... » read more

Printable circuits with silver nanowires Scientists at Duke University compared the conductivity of films made from different shapes of silver nanostructures and found that electrons move through films made of silver nanowires much easier than films made from other shapes, like nanospheres or microflakes. In fact, electrons flowed so easily through the nanowire films that they could function... » read more

Carbon nanotube transistors outperform silicon University of Wisconsin-Madison materials engineers created carbon nanotube transistors that outperform silicon transistors, improving the current 1.9 times. The new transistors are particularly promising for wireless communications technologies that require a lot of current flowing across a relatively small area. "This achievement has been a... » read more

Superfast fluorescence Duke University researchers developed an ultrafast light-emitting device, pushing semiconductor quantum dots to emit light at more than 90 gigahertz. This device could one day be used in optical computing chips or for optical communication between traditional electronic microchips. The new speed record was set using plasmonics. When a laser shines on the surface of ... » read more

Maintaining an unstable quantum system In an experiment that could have implications for quantum computers and quantum simulators, researchers at the Georgia Institute of Technology have demonstrated a way to maintain an unstable quantum system by applying bursts of microwave radiation – a quantum analog to vibrating the inverted pendulum. While a simple pendulum has two equilibrium point... » read more
