TV’s MacGyver never needed a spectrometer to save the day. But if he built one, the device would probably look like the one Jeffrey Warren and collaborators at the Public Laboratory for Open ...

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 ...

Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in ...

A research team has developed a broadband UV dual-comb spectrometer with which air pollutants can be continually measured and their reaction with the environment can be observed in real time. Sunlight ...

Researchers 3D printed a miniature ionizer, a key component of a mass spectrometer. Their device could someday enable an affordable, in-home mass spectrometer for health monitoring. Mass spectrometry, ...

The optical spectrometer plays an indispensable role in many scientific and industrial applications, such as material analysis, biological sensing, optical tomography and hyperspectral imaging.

Abstract: Wavelength Modulation Spectroscopy (WMS) using tunable diode laser is a versatile method for determination of concentration, temperature and velocity of absorbing gaseous molecules. This ...

The general MSI workflow for a preclinical pharmaceutical study is shown in Figure 1. Using a whole-body section from a dosed rat as an example, the test rat will be euthanized at the setup time point ...

If you’re trying to find ways to move away from single-use items for the sake of the planet, don’t overlook the humble AA (or AAA, or C, or D) battery. Rechargeable batteries can cost more than twice ...

Abstract: This paper presents a new approach of modeling the dynamic behavior of supercapacitors using impedance spectroscopy. The new Matlab/Simulink model can be used in simulating the voltage ...
