Securing memory Researchers at Columbia University suggest several ways to make computing more secure without imposing a system performance penalty. The efforts focus on memory security, specifically pointers. "Memory safety has been a problem for nearly 40 years and numerous solutions have been proposed. We believe that memory safety continues to be a problem because it does not distribute... » read more

Fast-charging EV battery Electric vehicle adoption faces challenges from consumers' range anxiety and the extended lengths of time needed to charge a car's battery. Researchers at Pennsylvania State University are trying to address this by developing lithium iron phosphate EV batteries that have a range of 250 miles with the ability to charge in 10 minutes. It also is expected to have a lifeti... » read more

Thinner, flexible touchscreens Researchers from RMIT University, University of New South Wales, and Monash University developed a thin, flexible electronic material for touchscreens. The material is 100 times thinner than current touchscreen materials. The new screens are still based on indium-tin oxide (ITO), a common touchscreen material. However, a liquid metal printing approach was used... » read more

Image-recognizing glass Engineers at the University of Wisconsin-Madison, MIT, and Columbia University developed a way to create 'smart' glass capable of performing image recognition tasks without the need for electronics or power. "We're using optics to condense the normal setup of cameras, sensors and deep neural networks into a single piece of thin glass," said Zongfu Yu, electrical and ... » read more

MicroLEDs: The Next Revolution In Displays?
By Mark LaPedus - 29 May, 2019 - Comments: 1

Flat-panel display technology is exploding on several fronts as more screens are required for more devices. But one type of display is generating an enormous amount of buzz in the market—microLEDs. Dozens of companies are working on micro-light emitting diodes (microLEDs), a technology that promises to provide better and brighter displays than current solutions in the market. Apple, Facebo... » read more

Future batteries could use a graphene sponge Researchers at Sweden’s Chalmers University of Technology devised a porous, sponge-like aerogel, made of reduced-graphene oxide, to serve as a freestanding electrode in the battery cell. This utilization has the potential to advance lithium sulfur batteries, which are said to possess a theoretical energy density about five times greater than lithi... » read more
