A new system for THz spectroscopy achieves both high spectral and spatial resolution at the same time, bypassing a ...

Elemental spectroscopy is a method employed to examine in-service fluid samples such as engine oil or hydraulic fluid, to determine the presence and quantity of different substances. This approach ...

A gap-controlled infrared technique makes it possible to study molecular interfaces with high sensitivity using affordable, widely available lab equipment. These molecular interfaces are everywhere—on ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

In traditional medical diagnostics, the procedure involves taking a patient biopsy sample and then meticulous analysis, which commonly utilizes microscopy methods within a laboratory setting. While ...

Current techniques for measuring nano/microplastic (N/MP) concentrations in soil require the soil organic matter content to be separated and have limited resolution for analyzing N/MPs sized <1 m.

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...

Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the colour of a pulsed laser, the team can ...

X-ray photoelectron spectroscopy is based on the same principle as all photoelectron spectroscopy methods. If a molecule or material is irradiated with light of a known energy above the ionization ...

Researchers have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by ...
