Importantly, many of these techniques still involve dissimilar materials at critical interfaces, such as using polymers or elastomers to pick up 2D flakes—materials ... remained stable after vacuum ...

Syrups made from cheap crops can easily be whisked into jars of premium honey to bulk them out, taking advantage of "outdated" adulteration tests that can only pick up on certain syrups.

Effective quality control ensures that plastics satisfy high criteria throughout the manufacturing process, from raw material inspection and polymerization monitoring to additive control and final ...

What is new is the combination of optofluidic force induction with Raman spectroscopy. Now the spectrum of the laser light scattered by individual particles in the liquid is also analyzed.

Here, we developed interpretable machine learning models that can classify uranium minerals by secondary oxyanion chemistry and other physicochemical properties based solely on Raman spectra. This new ...

A new portable Raman analyzer can accurately measure very low concentrations of hydrogen gas in ambient air, which could be ...

Raman spectroscopy is an analytical method capable of detecting various microorganisms and small particles. Here, we used 25–1000 nm polystyrene particles in aqueous suspensions, which are comparable ...
