XAS (X-ray Absorption Spectroscopy)

X-ray Absorption Spectroscopy (XAS) is a scientific technique used to study the properties of materials at the atomic level. It involves shining X-ray light on a sample, causing specific atoms within the material to absorb the X-rays. By measuring how much energy is absorbed, researchers can learn about the types of atoms present, their chemical states, and their surrounding environment. This information helps scientists understand various materials better, making XAS valuable in fields like chemistry, physics, and materials science, especially for investigating catalysts, batteries, and biological systems.
