A new computational approach reveals how subtle structural changes in polyheptazine imides can dramatically influence their ability to convert sunlight into chemical energy. Photocatalysis offers a ...

From brightly colored textile dyes to persistent pesticides and antibiotics, many modern pollutants dissolved in water—such ...

The application of modulated UV-C light to guavas—emitted in pulses or cycles rather than continuously—combated anthracnose. This fungal disease is caused by microorganisms belonging to the ...

Discover how to build a magnetic repulsion motor capable of lighting LED bulbs using only magnets and basic components. This step-by-step tutorial covers the construction of the magnetic base, the ...

An international research team has achieved record perovskite solar module stability under light, heat, and UV stress with a chemistry-driven passivation technology that is industry-compatible.

Researchers have built a new platform that produces ultrashort UV-C laser pulses and detects them at room temperature using atom-thin materials. The light flashes last just femtoseconds and can be ...

A programmable semiconductor changes its electronic properties under UV light and reverts under a different wavelength, enabling optical writing and reading for potential computing applications.

... this only occurs in specific, somewhat rare conditions. Otherwise, clouds generally tend to dampen UV rays. In short, while studies have found that clouds can ...

UV-C light is a type of ultraviolet light with shorter wavelength and more energy than UV light of type A and B. Photonic components operating in the UV-C range can unlock new opportunities across ...

Six species of North American bats—big brown bats (pictured), eastern red bats, Seminole bats, southeastern myotis, gray bats and Brazilian free-tailed bats—glow green under ultraviolet light, new ...

Glowing bats may sound like Halloween decor, but researchers in Georgia have discovered certain species of North American bats that are capable of the unusual trick. When placed under ultraviolet ...

Scientists have developed a fully transparent skin sensor that accurately measures UV radiation, detecting light and converting it to electrical signals. So when the Sun's rays reach damaging levels, ...
