Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...

(Nanowerk News) In a recent publication in Nature ("Near-ultraviolet photon-counting dual-comb spectroscopy"), researchers at the Max Born Institute (MBI) in Berlin, Germany, and at Max-Planck ...

What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

Lithuanian researchers at the Center for Physical Sciences and Technology (FTMC), Habil. Dr. Gediminas Niaura and Dr. Martynas Talaikis, together with international colleagues, have for the first time ...

UV-Vis spectroscopy is an analytical technique that measures the amount of discrete wavelengths of UV or visible light that are absorbed by or transmitted through a sample in comparison to a reference ...

Combined spectroscopic measurements and theoretical calculations bring to light an ultrafast excited-state deactivation process in peptides that may contribute to the ultraviolet photostability of ...

You may have certainly enjoyed an authentic honey, wine, or olive oil. Yet, each of these foods are at risk for fraud. To mitigate and investigate food fraud, researchers use analytical methods, such ...

Ultraviolet spectroscopy plays a critical role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are essential for tests of fundamental physics, ...
