An introduction to Coulomb’s Law and electric fields explained in a clear and simple way. Learn how electric charges interact, how force depends on distance, and how electric fields describe these ...

Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next ...

Researchers at Princeton and North Carolina State University have developed a technique that substantially improves the ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...

The US National Institute of Standards and Technology (NIST) is discussing plans to eliminate an entire team responsible for publishing and maintaining critical atomic measurement data in the coming ...

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...

Abstract: Over the past two decades, research on integrating spectroscopy and Artificial Intelligence (AI) for material analysis across various industrial sectors has been widespread. Despite this, ...

Scientific discovery has always depended on the tools available to researchers. With the advancement of technology, the range and capability of high-tech instruments have dramatically expanded, ...

NMR spectroscopy is a powerful technique that is ideally suited to the characterization and analysis of a diverse array of chemical compounds. Unlike many other analytical techniques, NMR spectroscopy ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...
