In an effort to reveal the inner workings of a protein that serves as a cell's damage detection system, scientists at Johns ...

JWST infrared technology pierces cosmic dust with unmatched clarity, revealing hidden star nurseries and structures no ...

US-Italy researchers have used quantum-mechanical simulations to resolve a decades-old puzzle about how ultraviolet ...

When ultraviolet light hits ice—whether in Earth's polar regions or on distant planets—it triggers a cascade of chemical ...

Before a spectrometer can do any useful work, it needs to be calibrated to identify wavelengths correctly. This is usually done by detecting several characteristic peaks or dips in a well-known light ...

Octocrylene (2-ethylhexyl 2-cyano-3,3-diphenyl-2-propenoate) is present in several sunscreens and is known to work synergistically with UV filters. We prepared eight octocrylene-related compounds to ...

Spectroscopy is the study of how electromagnetic radiation interacts with matter and is used as an analytical technique in many scientific disciplines. 1 The key properties of light, including ...

UV VIS spectroscopy is a powerful analytical technique, but misconceptions about its capabilities and limitations are more common than you might think. From its use in simple color measurement to its ...

The UV-Vis spectrum is a graphical representation of light absorption. Wavelength (nm) is shown on the x-axis, representing the energy of absorbed light; absorbance or transmittance is plotted on the ...

Abstract: Oil-immersed power transformers are critical assets in electrical power system networks from generation to utilization. The insulating oil degrades as it comes under thermal and electrical ...
