In a remarkable celestial event, the interstellar comet 3I/ATLAS is making its closest approach to Earth this Friday. First spotted in July, this comet is now on its way out of our solar system, but ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...

Abstract: Over the past two decades, research on integrating spectroscopy and Artificial Intelligence (AI) for material analysis across various industrial sectors has been widespread. Despite this, ...

Scientific discovery has always depended on the tools available to researchers. With the advancement of technology, the range and capability of high-tech instruments have dramatically expanded, ...

NMR spectroscopy is a powerful technique that is ideally suited to the characterization and analysis of a diverse array of chemical compounds. Unlike many other analytical techniques, NMR spectroscopy ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. Published as part of Chemical Reviews virtual special issue ...

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 ...
