A wireless charger that’s compatible with different consumer electronics from different brands is one step closer to becoming a reality thanks to research by electrical engineers at the University of California, San Diego. Researchers have developed a dual frequency wireless charging platform that could be used to charge multiple devices, such as smartphones, smartwatches, laptops and tablets, […]
Discovery Paves Way for New Kinds of Superconducting Electronics
Physicists at UC San Diego have developed a new way to control the transport of electrical currents through high-temperature superconductors — materials discovered nearly 30 years ago that lose all resistance to electricity at commercially attainable low temperatures. Their development, detailed in two separate scientific publications, paves the way for the development of sophisticated electronic […]
X-Ray imaging reveals secrets in battery materials
In a new study, researchers explain why one particular cathode material works well at high voltages, while most other cathodes do not. The insights, published in the 19 June issue of the journal Science, could help battery developers design rechargeable lithium-ion batteries that operate at higher voltages. Researchers used a powerful X-ray imaging […]
Charged Holes in Graphene Increase Energy Storage Capacity
Engineers at the University of California, San Diego have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon. The research, published recently online in the journal Nano Letters, may provide a better understanding of how to improve the energy storage ability of capacitors for […]
Solar Power Material Converts 90% of Captured Light into Heat
A multidisciplinary engineering team at the University of California, San Diego developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in […]
Electronics that Stretch at the Molecular Level
Nanoengineers at the University of California, San Diego are asking what might be possible if semiconductor materials were flexible and stretchable without sacrificing electronic function? Today’s flexible electronics are already enabling a new generation of wearable sensors and other mobile electronic devices. But these flexible electronics, in which very thin semiconductor materials are applied to […]
