Liquefied gas electrolyte Researchers at UC San Diego, U.S. Army Research Laboratory, and South 8 Technologies developed an electrolyte that could enable the replacement of the graphite anode in lithium-ion batteries with lithium-metal. Such a change would increase energy density 50% at the cell level, making for lighter batteries with more capacity. However, lithium-metal anodes are not compa... » read more

Wearable heart monitoring Researchers at the University of Texas at Austin developed a lightweight, stretchy heart monitoring patch that can be worn externally. Along with being easy to wear, the graphene-based 'e-tattoo' is more accurate than existing electrocardiograph machines, according to the team. The e-tattoo measures cardiac health using both electrocardiograph and seismocardiograph... » read more

2D straintronics Researchers at the University of Rochester and Xi’an Jiaotong University dug into how 2D materials behave when stretched to push the boundaries of what they can do. "We're opening up a new direction of study," says Stephen Wu, assistant professor of electrical and computer engineering and physics at Rochester. "There's a huge number of 2D materials with different properti... » read more

Improving IGBTs Researchers at the University of Tokyo developed a power switching device that surpasses previous performance limits, showing that there may still be gains ahead for the silicon-based devices, which have been thought to be approaching their limits. The team's improved insulated gate bipolar transistor (IGBT) used a scaling approach, and simulations showed that downscaling pa... » read more

Quantum dots plus perovskites Researchers at the University of Toronto and KAUST created a hybrid material for solar cells that utilizes both perovskites and quantum dots. Both quantum dots and perovskites suffer from instability: perovskites degrade quickly and certain types become incapable of fully absorbing solar radiation at room temperature, while quantum dots must be covered with a p... » read more

Archival storage Researchers at Harvard University and Northwestern University propose a method of long-lived archival data storage using low-weight molecules. DNA has been explored as a method of archival storage, but the researchers argue that it is inadequate, as the DNA macromolecule is large and requires skilled, repetitive labor to encode and read. Instead, the researchers turned... » read more

More speculative vulnerabilities Security researchers at the Graz University of Technology, KU Leuven, Cyberus Technology, and Worcester Polytechnic Institute point to two new speculative execution vulnerabilities related to Meltdown and Spectre. The first, which they dubbed ZombieLoad, uses a similar approach to Meltdown. After preparing tasks in parallel, the processor needs to discard th... » read more

Detecting malware with power monitoring Engineers at the University of Texas at Austin and North Carolina State University devised a way to detect malware in large-scale embedded computer systems by monitoring power usage and identifying unusual surges as a warning of potential infection. The method relies on an external piece of hardware that can be plugged into the system to observe and m... » read more
