Many types of smart devices are readily available and convenient to use. The goal now is to make wearable electronics that are flexible, sustainable and powered by ambient renewable energy.

In the race to design the world’s first universal quantum computer, a special kind of diamond defect called a nitrogen vacancy (NV) center is playing a big role. NV centers consist of a nitrogen atom and a vacant site that together replace two adjacent carbon atoms in diamond crystal. The defects can record or store quantum information and transmit it in the form of light, but the weak signal is hard to identify, extract and transmit unless it is intensified.

Scientists at Lawrence Livermore National Laboratory study potential of drag-reducing devices on semitrucks to conserve billions of gallons, save tens of billions of dollars and spare tens of millions of tons of CO2
