Researchers have demonstrated a high performance MXene-GaN-MXene based multiple quantum well photodetector prepared on patterned sapphire substrate by facile drop casting.
An international research team has created an extremely energy-efficient optical switch that could replace electronic transistors in a new generation of computers manipulating photons rather than electrons.
Scientists have created cell-size robots that can be powered and steered by ultrasound waves. Despite their tiny size, these micro-robotic swimmers - whose movements were inspired by bacteria and sperm - could one day be a formidable new tool for targeted drug delivery.
