Staff at the Osaka World Expo are wearing neck fans powered by next-generation perovskite solar cells that weigh less than a ...

A theoretical model for the dependence of the diode forward voltage (V/sub f/) on junction temperature (T) is developed. A new expression for dV/sub f//dT is derived that takes into account all ...

Abstract: Synaptic transistors mimicking the biological synapse's short term plasticity and short-term memory property were demonstrated using the amorphous indium-gallium-zinc oxide channel in ...

That’s because melanin absorbs the dangerous UV rays that can do serious skin damage. A sunburn develops when the amount of UV damage exceeds the protection that the skin's melanin can provide. A ...
