U.S. Army Research Laboratory electronics engineer Dr. Charles Kamhoua poses in the ARL Network Science Research Laboratory in Adelphi, Maryland, where he works on cloud security and the management of cyberspace risks.
The researchers' vision is of vehicles where a large part of the car-body or aeroplane-fuselage consists of structural lithium ion batteries. Multi-functional carbon fibre can work as battery electrodes and load-bearing material consecutively. The researchers work with structural lithium ion batteries where the negative electrodes are made of carbon fiber and the positive electrodes are made of cathode-coated carbon fiber. In the picture, the battery is charged, which means the negative electrode is filled with positively charged lithium ions.
Laser that heats the air over 1,500 degrees Celsius and produces a shock wave to expel sideways the suspended water droplets that make up the cloud.
The hot-press procedure, developed at Drexel, melts sulfur into the nanofiber mats in a slightly pressurized, 140-degree Celsius environment -- eliminating the need for time-consuming processing that uses a mix of toxic chemicals, while improving the cathode's ability to hold a charge after long periods of use.
BioBits kits are designed to be used by students and teachers with no biological training. They use simple, hands-on experiments, some using common household fruits to teach concepts of synthetic and molecular biology.
