Extending the life of low-cost, compact, lightweight batteries
Nov 09, 2018 (SPX)
While typical rechargeable lithium-ion batteries only lose about 5 percent of their charge after a month of storage, they are too costly, bulky, or heavy for ma...
Batteryless smart devices closer to reality
Nov 08, 2018 (SPX)
These battery-free objects, which feature an IP address for internet connectivity, are known as Internet of Things (IoT) devices. If an IoT device can operate w...
Inside job: A new technique to cool a fusion reactor
Nov 06, 2018 (SPX)
During these so-called disruptions, the rapid release of the energy in the plasma can damage the fusion device: Intense heat can vaporize or melt the walls, lar...
Taming plasmas: Improving fusion using microwaves
Nov 06, 2018 (SPX)
Fusion takes place when fast moving atomic particles slam into each other and stick together. The particles need to be so hot that atoms break down, leaving a g...
