How ultraviolet light (UV) works as a disinfection technology depends upon the wavelength(s) being employed. The UVC band with a wavelength of 200-280nm has emerged as a viable solution for interior ...

In a recent study published in the Journal of Photochemistry and Photobiology, a team of researchers analyzed the effect of ultraviolet (UV) and violet light of different wavelengths on the virulence ...

Forbes contributors publish independent expert analyses and insights. Jamie Gold writes about wellness design and related housing topics. When Covid reached the U.S. in force earlier this year, very ...

Ultraviolet light has a long history as a disinfectant, and the SARS-CoV-2 virus, which causes COVID-19, is readily rendered harmless by UV light. The question is how best to harness UV light to fight ...

High-precision sine-commutated stepper-motors let a medical phototherapy device beam UV light only at areas of a patient’s skin that need it. A PD4-N6018 Model stepper sits in the crossbeam (Y2 axis) ...

Ultraviolet has very short and energetic wavelengths that are shorter than violet on the visible spectrum. But can people see UV? When you purchase through links on our site, we may earn an affiliate ...

UVC light has been shown to quickly inactivate the novel coronavirus, SARS-CoV-2. It can be an effective disinfectant but needs to be used correctly to avoid damage to the skin and eyes. Ultraviolet ...

UV polymers are used in 3D printing, toys, and pens, but now the materials has made its way into our hearts—literally. Photopolymers are well known in 3D printing. But how do they work and how did ...

We are faced with a global epidemic of myopia (short-sightedness) because we are deprived of deep violet light (360-400 nm). Myopia is projected to rise from 23 to 50 percent of the world’s population ...
