“We’ve created a spectrometer that operates quickly, at low voltage, and that is sensitive to a wide spectrum of light,” ...

Addressing UV risks requires sustainable solutions. Advances in bio-based materials and composites are redefining UV ...

LOS ANGELES — “Right here is my UV safety station,” said licensed clinical social worker Phil Donney, pointing to his hat, sunscreen and sunglasses. Donney's daily diligence is for good reason. “One ...

The UV spectrum is divided into three main ranges: UV-A (315–400 nm), UV-B (280–315 nm), and UV-C (<280 nm). While UV-C rays are absorbed by the ozone layer, UV-A and UV-B reach the Earth’s surface in ...

Finsen hypothesised that light --specifically the chemical rays in the blue and ultraviolet spectrum could act directly on the bacteria and stimulate healing of the infected tissue.

So as the transistors got smaller, higher and higher frequency of light is required, today going increasingly into the upper end of the ultraviolet spectrum. The first step of leaving the visible ...

Researchers conducted comprehensive safety assessments on triazine UV filters ethylhexyl triazone (EHT) and diethylhexyl butamido triazone (HEB). Through bacterial reverse mutation, chromosomal ...

In the early 1990s, eight people tried to survive in a hermetically sealed glass structure filled with miniature forests, oceans and savannah.

July is UV Safety Awareness Month, highlighting the growing risks of UV radiation and encouraging the use of protective measures to reduce sun-related health threats.
