Electrode could enable electric cars that charge in minutes

C&EN: Every year, electric vehicles’ driving range grows. But the hours it takes to recharge their batteries slows them down. Researchers now report a battery electrode based on 2D black phosphorus that they say could be used to make batteries…

A hydrogel that could help repair damaged nerves

NANO Magazine: Injuries to peripheral nerves—tissues that transmit bioelectrical signals from the brain to the rest of the body—often result in chronic pain, neurologic disorders, paralysis or disability. Now, researchers have developed a stretchable conductive hydrogel that could someday be used…

Electronic Blood Vessels to the Rescue

IEEE Spectrum: The number one cause of mortality worldwide is cardiovascular disease. Now scientists reveal electronic blood vessels might one day use electricity to stimulate healing and deliver gene therapies to help treat such maladies, a new study finds. One-third of…

Sensor Rapidly Detects SARS-CoV-2, Antibodies, and Inflammatory Markers

Laser Focus World: Researchers at Caltech have developed a low-cost multiplex test that can rapidly provide three different types of data on COVID-19. The test can detect the presence of SARS-CoV-2,…
