Highly energetic, "hot" electrons have the potential to help solar panels more efficiently harvest light energy. But up until now, scientists haven't been able to measure the energies of those electrons, limiting their use. Researchers have now demonstrated how a technique using a scanning tunneling microscope integrated with lasers and other optical components reveals the … [Read more...] about Discovery unlocks ‘hot’ electrons for more efficient energy use

Researchers have set a record for carbon dioxide capture using Metal Organic Frameworks (MOFs). The technology resembles a sponge filled with tiny magnets. … [Read more...] about New record for carbon dioxide capture

A team led by researchers at Carnegie Mellon University has created a new technology that enhances scientists' ability to communicate with neural cells using light. Tzahi Cohen-Karni, associate professor of biomedical engineering and materials science and engineering, led a team that synthesized three-dimensional fuzzy graphene on a nanowire template to create a superior … [Read more...] about A remote control for neurons

Washington State University (WSU) and Pacific Northwest National Laboratory (PNNL) researchers have created a sodium-ion battery that holds as much energy and works as well as some commercial lithium-ion battery chemistries, making for a potentially viable battery technology out of abundant and cheap materials. The team reports one of the best results to date for a sodium-ion … [Read more...] about Researchers develop viable sodium battery

People love their electric cars. But not so much the bulky batteries and related power systems that take up precious cargo space. Help could be on the way from a gallium oxide-based transistor under development at the University at Buffalo. In a study published in the June edition of IEEE Electron Device Letters, electrical engineers describe how the tiny electronic switch can … [Read more...] about Paper-thin gallium oxide transistor handles more than 8,000 volts
