An international research team has found that defects in the crystalline structure of perovskite—which is used to make solar cells—can be healed permanently by exposing them to light, improving the material in its generation of solar energy.
Researchers from the University of Maryland and the U.S. Army Research Laboratory have developed a new water-based lithium-ion battery that can reach the critical 4.0 volt threshold without the danger of explosion and fire inherent in non-aqueous lithium-ion batteries.
In partnership with engineers from Hyundai, Jonathon Keats, an experimental philosopher and artist, has developed, Roadable Synapse, a concept that uses vehicle sensors to convey a sense of what the car is experiencing directly to the driver.
