In addition to cancer induction, erythema (sunburn), and skin aging are also known effects of ultraviolet skin exposure. Because the biological effects are dependent on the time of exposure, the ...

Photolithography at a wavelength of 193 nm in the deep UV with water immersion lenses can now produce microelectronics containing features with a half-pitch as small as 40 nm. The big question is ...

Ultraviolet (UV) lamps emit electromagnetic radiation with a wavelength between 10 nanometers (nm) and 400 nm, which is below the visible light spectrum. UV lamps have industrial uses in sterilization ...

The star system tells you the percentage of UVA radiation that is absorbed by the sunscreen in comparison to how much UVB is absorbed. Ultraviolet A and B refer to different wavelengths of ...
