What is Atomic Absorption Spectrometry? AAS is a technique for determining how much of a specific element is present in the specimen under study. The uptake of optical radiation by neutral atoms in ...

What is X-ray Absorption Spectroscopy (XAS)? X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique that probes the local atomic and electronic structure of materials by measuring the ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

However, power-law relaxation can originate from mechanisms other than diffusion. Here we report transient absorption spectroscopy measurements on CdS and CdSe nanorods recorded at temperatures ...

Spectroscopy has been described as ‘applied quantum mechanics’ and the right spectroscopic technique can recover relatively direct information on the electronic configuration of a sample. For example, ...

What’s the story behind DNA melting temperature analysis? UV-Visible absorption spectroscopy can be used to assess the characteristics of deoxyribonucleic acid (DNA), a naturally occurring polymer ...
