Durian supercapacitors Researchers from the University of Sydney developed a method that uses durian and jackfruit waste to create supercapacitors. Supercapacitors are capable of quickly storing and discharging energy. The team says their fruit-based material is more efficient than ones typically made from activated carbon. "Using durian and jackfruit purchased from a market, we conver... » read more

Optimizing fiber networks Researchers at Chalmers University of Technology are working towards reducing the energy consumption of fiber optic communications before the amount of electricity required by the Internet becomes too great to manage. To improve overall efficiency, the team tackled several aspects of fiber optic cables. One of the major energy drains the team identified was the err... » read more

Balancing battery capacity and stability Researchers at Rice University are working to develop batteries that are better geared toward electric cars and more robust off-grid energy storage by digging into why lithium gets trapped in batteries, thus limiting the number of times it can be charged and discharged at full power. The team found that by not maxing out a battery's storage capacity,... » read more

Infrared nanoantenna Researchers at the University of Würzburg built a nanoantenna capable of generating directed infrared light. The Yagi-Uda antenna is the smallest of its type yet created. "Basically, it works in the same way as its big brothers for radio waves ," said René Kullock, a member of the nano-optics team at Würzburg. An AC voltage is applied that causes electrons in the met... » read more

Accelerator-on-chip Researchers at Stanford University and SLAC National Accelerator Laboratory created an electron-accelerator-on-chip. While the technique is much less powerful than standard particle accelerators, it can be much smaller. It relied upon an infrared laser to deliver, in less than a hair’s width, the sort of energy boost that takes microwaves many feet. The team carved ... » read more

Two-layer MRAM Scientists at Tokyo Institute of Technology propose a simpler MRAM construction that could perform faster with less power than conventional memories. The idea relies on unidirectional spin Hall magnetoresistance (USMR), a spin-related phenomenon that could be used to develop MRAM cells with an extremely simple structure. The spin Hall effect leads to the accumulation of elect... » read more

Replenishing The Grid With A SiC-Based Bi-Directional On-Board Charger
By Wolfspeed, a Cree Company - 16 Dec, 2019 - Comments: 0

Range anxiety and charger availability have long been the main hurdles to the adoption of electric vehicles. But even as car makers have demonstrated their batteries can go longer distances and charging stations have proliferated, challenges with EV charging remain as well as opportunities to load balance power grids. The migration to electric vehicles also means looking at how they can bett... » read more
