Power/Performance Bits: Nov. 10

Singing to your storage Existing research on 'racetrack memory', which uses tiny magnetic wires, each one hundreds of times thinner than a human hair, down which magnetic bits of data run like racing cars around a track, has focused on using either magnetic fields or electric currents to move the data bits down the wires. However, both these options create heat and reduce power efficiency. ... » read more

Power/Performance Bits: Aug. 19

Spray-on power In a discovery that could help cut the cost of solar electricity, a team of scientists at the University of Sheffield has fabricated perovskite solar cells using a spray-painting process. The researchers had used the spray-painting method previously to produce solar cells using organic semiconductors - but using perovskite is a major step forward, they asserted. Efficient ... » read more
