The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the ...

“Visible light is much gentler and can penetrate deeper, making it more suitable for real-world applications,” says Huaping Xu, a professor at Tsinghua University and one of the study’s corresponding ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

Adding zinc ions to lithium niobate crystals cuts the energy needed for polarization switching by 69%, enabling visible-light programming of memristors for brain-inspired computing.

One way that chemists recycle CO 2 into valuable products is through a process called electrochemical reduction, where a stream of CO 2 gas moves through an electrolysis cell that breaks the CO 2 and ...
