When light reflects off a surface, not all of it reflects off at the same wavelength; some photons impart a portion of their ...

As instruments grow faster, leaders say clinical impact will depend on trust, standards, data, and assays built for real ...

Quantum properties of light are extremely delicate. When researchers attempt to measure them, even small losses on the way to ...

Abstract: In this paper, equivalent electric circuit models of a commercial 1.2-kW proton exchange membrane (PEM) fuel cell stack are proposed based on AC impedance studies. The PEM fuel cell stack ...

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system ...

The aim of this article was to develop a chemometric methodology for determining the chemical profile of cocaine samples seized in Minas Gerais State, Brazil. The adulterant detection and the cocaine ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. Optical spectroscopy serves as a fundamental technique in ...

This article discusses the identification of polymers such as ABS, PE, PS, PET, and PMMA in various dyes using Raman spectroscopy. Rapid and non-destructive identification is achieved once a suitable ...

Note that the Rodgers lab have an in-house version of OXSA ("RodgersSpectroTools") that contains many extensions particularly for use with Siemens 7T MRIs (Magnetom and Terra) on VB17 and VE-series ...

What is time-of-flight mass spectrometry? How ToF MS has gained more interest since the commercialization of MALDI. Why a high-speed ADC is key to ToF MS performance. Mixed-signal front end that ...

We describe a new comprehensive and open-source MATLAB library, called the Visual Display Interface (VDI), designed to process, model, quantify and visualize magnetic resonance spectroscopy (MRS) and ...
