Spatial heterodyne spectroscopy (SHS) is a static interferometric technique that combines the high resolution of Fourier transform spectroscopy with the robustness of fixed-geometry optics. By ...

Microwave spectroscopy probes the rotational transitions of gas-phase molecules in the gigahertz region, yielding precise rotational constants that directly relate to the molecular moment of inertia ...

Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a fundamentally new type of optical spectrometer that delivers ...

Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in ...

Researchers have developed new analytical methods to rapidly analyze fuels and complex petroleum products by using high-resolution mass spectrometry. U.S. Naval Research Laboratory researcher Mark ...

In Star Trek, Mr. Spock’s hand-held tricorder can instantly tell what something is made of. We don’t have tricorders yet, but we’re getting close. Portable devices just a little too big to hold in one ...

In 1928, Indian physicist Sir C. V. Raman and his colleague K. S. Krishnan discovered that when light interacts with matter, parts of the scattered light undergo changes in energy due to interaction ...

LIFT, operated by the American Lightweight Materials Manufacturing Innovation Institute, is a Detroit-based public-private partnership between the Department of Defense, industry, and academia. Its ...

An illustration featuring a spectrometer with its scanner set on a bag of substances. The background features several geometric shapes and math symbols. The words "methamphetamine" and ...

Engineering material surface properties can influence some of the most important characteristics of materials, such as corrosion resistance, adhesion, color, conductivity, biocompatibility, and many ...

Some years ago, David Gehl made an unusual trip to Siberia. “I went to lots of sawmills and forests and came back from Russia and China with, like, 20 kg of wood boards on my back,” he recalls. Gehl ...

A research team has developed a broadband UV dual-comb spectrometer with which air pollutants can be continually measured and their reaction with the environment can be observed in real time. Sunlight ...
