Semiconductor quantum transistor opens the door for photon-based computing
Semiconductor quantum transistor opens the door for photon-based computing

Researchers from the University of Maryland claim to have demonstrated the first single-photon transistor using a semiconductor chip. Making a quantum transistor triggered by light has been a previous challenge because it requires that the photons interact with each other, the researchers explain. According to the team, the device is compact: roughly one million of these new transistors could fit inside a single grain of salt. It is also fast and able to process 10billion photonic qubit...

Smart bandages designed to monitor and tailor treatment for chronic wounds
Smart bandages designed to monitor and tailor treatment for chronic wounds

A prototype bandage designed to actively monitor the condition of chronic wounds and deliver appropriate drug treatments to improve the chances of healing has been developed by Tufts University engineers. The researchers designed the bandages with heating elements and thermoresponsive drug carriers that they say can deliver tailored treatments in response to embedded pH and temperature sensors that track infection and inflammation. The hope is these smart bandages could provide real tim...

High-power thermoelectric generator utilises thermal difference of only 5°c
High-power thermoelectric generator utilises thermal difference of only 5°c

A silicon-nanowire thermoelectric generator has been developed by a team of researchers from Waseda University, Osaka University, and Shizuoka University. According to the Japanese researchers, this experimentally demonstrated a high-power density of 12 microwatts per 1cm2, enough to drive sensors or realise intermittent wireless communication, at a small thermal difference of only 5ºC. Silicon-based thermoelectric generators conventionally employed long, silicon nanowires of about...

Self-heating, fast-charging battery makes electric vehicles climate-immune
Self-heating, fast-charging battery makes electric vehicles climate-immune

A self-heating battery has been created by a team of Penn State engineers to combat the issue surrounding climate restrictions, rapid recharging and electric vehicles (EV). "EVs are popular on the west coast because the weather is conducive," explains assistant research professor, Xiao-Guang Yang of Penn State. "Once you move them to the east coast or Canada, then there is a tremendous issue. We demonstrated that the batteries can be rapidly charged independently of outside ...

BNAs improve performance of Li-ion batteries
BNAs improve performance of Li-ion batteries

The effect of hierarchical Bi2MoO6 nanosheet arrays growing on 3D Ni foam synthesised by one-step template-free route has been investigated by a team form Northeastern University. According to Northeasten, the obtained BNAs used directly as binder-free integrated electrode for Li-ion batteries (LIBs) exhibits a “super high” reversible discharge capacity of 2311.7 μAh/cm2, and an “excellent” cycle stability. Commercial LIBs mainly use graphite as the anode mate...
