So far, the study of the Raman effect has been confined to the visible region of the spectrum only. By the use of an all-quartz apparatus similar to that of glass used by Prof. Wood (Phil.

Raman spectroscopy is an optical technique that detects intrinsic vibrational, rotational and other low-frequency modes in molecules upon inelastic scattering of monochromatic light. Because ...

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 ...

To train these algorithms, they need high-quality reference data. That’s where NIST’s database comes in. Called the Near-Infrared Spectra of Origin-defined and Real-world Textiles, or NIR-SORT, it ...

In a study recently published in Science Advances, researchers from Osaka University have reported a method that gives high-resolution Raman microscopy images. Raman microscopy is a useful ...

The National Institute of Standards and Technology (NIST) recently proposed standardizing the block and key size used in the Advanced Encryption Standard (AES) to 256 bits. According to NIST ...

The 2004 tsunami affected a number of countries, making it a truly global disaster. There are six critical lessons we must consider. First, the importance of mangroves in providing natural ...

The study details a cost-effective method for producing ethylbenzene -- an additive that improves the functional characteristics of sustainable aviation fuels -- from polystyrene, a hard plastic ...
