In this paper we report a newly developed technique – laser calorimetry spectroscopy (LCS), which is a combination of laser absorption spectroscopy and calorimetry - for the detection of gases ...

Photothermal interferometry is an ultra-sensitive spectroscopic means for trace chemical detection in gas- and liquid-phase materials. Previous photothermal interferometry systems used free-space ...

Expert sommeliers can take a whiff of a glass of wine and tell you a lot about what's in your pinot noir or cabernet sauvignon. A team of physicists at CU Boulder and the National Institute of ...

Alkanolamines are polyfunctional molecules that include the properties of both alcohols and amines, and because of this they serve as key intermediates in the development of a wide range of products.
