Elpasolites are expected to be promising photovoltaic semiconductor alternatives to lead-based perovskite semiconductors. Concern over the stability and toxicity of lead halide perovskites has led to ...

Some experts believe that mental health concerns may be an unexpected side effect of increased social media use.

We demonstrate a multi-wavelength quantum light source utilizing dual pumps and realize the generation of 25-pair correlated photons in a silicon nitride micro-ring resonator. The properties of ...

By Ashley Strickland, CNN (CNN) — A newly discovered object speeding through our solar system is sparking excitement among astronomers because it’s not from around here. Believed to be a comet ...

Researchers at The University of Texas at Austin have created a new, quick, and accurate 3D printing technique that uses various light colors to seamlessly combine soft and hard qualities into a ...

In this work, single-light-actuated dual-mode propulsion at the liquid/air interface is realized by using flexible, superhydrophobic, and thermostable photothermal paper made from flexible ultralong ...

A solar minigrid in a Goma neighborhood where almost everyone lacked access to electricity just five years ago is offering a flicker of hope despite widespread poverty and the city’s violent ...

Street lights erase the shadows where attackers once hid. Noisy, polluting diesel generators have gone silent. In several Goma neighborhoods where almost nobody had electricity just five years ago, a ...

The technology, detailed in the journal Nature Materials, relies on a specially formulated liquid resin and a unique dual-light printing process. Unlike traditional 3D printing, which typically ...
