How cars 'waste' two thirds of their fuel

With the rise in gas prices showing no signs of abating, it seems like an appropriate time to ask ourselves: are our cars not efficient enough? Europe has decided to ban the production of new combustion engine-powered vehicles ...

Cooling down solar cells, naturally

A bright, sunny, cloudless day might seem like the optimal setting for solar cells. But too much sun, and too much heat, can actually reduce the efficiency of photovoltaics.

A novel integrated system of neuromorphic devices

Neuromorphic computing is an information processing model that simulates the efficiency of the human brain with multifunctionality and flexibility. Currently, artificial synaptic devices represented by memristors have been ...

Photosynthesis copycat may improve solar cells

A relatively new kind of semiconductor, layered atop a mirror-like structure, can mimic the way that leaves move energy from the sun over relatively long distances before using it to fuel chemical reactions. The approach ...
