11 ore fa · In “Ultraviolet,” by Aida Salazar, and “Mid-Air,” by Alicia D. Williams, the thunderstorm of adolescence splits open a once peaceful sky.
1 giorno fa · Perovskite solar cells are often tested indoors under conditions that do not represent outdoor use. Fei et al. found that faster degradation of the cells in outdoor testing stems from higher ultraviolet levels that cause debonding at the indium-tin oxide and hybrid hole-transporter layer interfaces.
20 ore fa · DRS Daylight Solutions produces compact, high-power laser modules in the ultraviolet (UV-A) spectral range. Its fiber-optic pigtailed package provides CW power levels up to 1 Watt at 375 nm ...
20 ore fa · Second harmonic generation (SHG) response, birefringence, and ultraviolet (UV) absorption edge are three crucial parameters of UV nonlinear optical (NLO) crystals. However, striking a balance among these parameters has been a challenging endeavor. The synergistic combination of mixed chromophores is regarded
3 giorni fa · Developing high-performance polarization-sensitive ultraviolet photodetectors is crucial for their application in military remote sensing, detection, bio-inspired navigation, and machine vision. However, the significant absorption in the visible light range severely limits the application of polarization-sensitive ultraviolet photodetectors, such as high-quality anti-interference imaging.
20 ore fa · Here, we report a new donor-acceptor (D-A) covalent organic framework (COF) with a wide absorption range from 200 nm to 900 nm (ultraviolet-visible-near infrared light).
1 giorno fa · The UV Index is a measure of the ultraviolet (UV) radiation level at the Earth's surface, developed by the World Health Organization, the United Nations Environment Programme, and the World Meteorological Organization.
