Researchers improved perovskite-based technology in the entire energy cycle, from solar cells harnessing power to LED diodes to light the screens of future electronic devices and other lighting applications.
Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution control systems to further reduce emissions of smog-causing nitrogen oxides in diesel exhaust.
Supercapacitors promise recharging of phones and other devices in seconds and minutes as opposed to hours for batteries. But current technologies are not usually flexible, have insufficient capacities, and for many their performance quickly degrades with charging cycles. Researchers now have found a way to improve all three problems in one stroke.
This miniscule wire - comprising a carbon nanotube located inside a boron nitride nanotube - can be produced on a preparative scale and may represent an important step towards the miniaturisation of electronic devices.
