To improve models for drilling, hydraulic fracturing and underground storage of carbon dioxide, Oak Ridge National Laboratory scientists used neutrons to understand how water flows through fractured rock.
The lighter wand for your gas BBQ, a submarine’s sonar device and the ultrasound machine at your doctor’s office all rely on piezoelectric materials, which turn mechanical stress into electrical energy, and vice versa.
In a rechargeable battery, the electrolyte transports lithium ions from the negative to the positive electrode during discharging. The path of ionic flow reverses during recharging.
