A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open ...

Scientists have successfully visualized terahertz radiation, popularly known as T-rays, using a crystal called mayenite (Ca 12 Al 14 O 33). Their method cleverly utilizes the rattling motion caused by ...

Newly developed molecular system makes possible the efficient conversion of even weak visible light from sunlight and indoor LEDs into ultraviolet light Light-powered processes from hydrogen ...
