A new mass spectrometry technique captures molecules of lower abundance in a sample, providing a more comprehensive sample ...

The composition of complex mixtures of molecules can be determined using NMR spectroscopy. Each of the thin glass tubes is filled with an extract of sea water that contains a few milligrams of ...

Determination of laser frequency with high resolution under continuous and abrupt tuning conditions is important for sensing, spectroscopy, and communications. We show that a single microresonator ...

Color, as the way light's wavelength is perceived by the human eye, goes beyond a simple aesthetic element, containing important scientific information like a substance's composition or state.

Developing targeted small molecule quantitative workflows for clinical research presents many challenges to researchers. From determining the optimum methods needed to enhance selectivity and ...

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 spectrometer is one of those tools that many of us would love to have, but just can’t justify the price of. Sure there are some DIY options out there, but few of them have the convenience or ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...
