X-ray photoelectron spectroscopy for sulfide glass electrolytes in the systems Li₂S–P₂S₅ and Li₂S–P₂S₅–LiBr

X - Ray Photoelectron Spectroscopy of Silicate Glasses

X-ray photoelectron spectroscopy (XPS) is a powerful technique capable of providing unique information about the structural chemistry of glasses. However, inappropriate procedures for the preparation of sample surfaces or the lack of reliable methods to overcome electrostatic charging effects during analysis of dielectric materials can cause spurious features to be introduced or intrinsic featu...

Soft X-ray Photoelectron Spectroscopy in Silicon Clathrate Superconductors

Silicon clathrate compounds consist of fullerenelike polyhedral Si-cages, which share their faces to form a three-dimensional Si-sp 3 covalent network. Guest elements such as an alkali atom or an alkaliearth one can be encapsulated in the cage. Recently, these compounds have attracted strong interest due to the discovery of superconductivity in a metal-doped silicon clathrate, Ba6Na2Si46 [1], a...

X-ray induced damage in DNA monitored by X-ray photoelectron spectroscopy.

In this work, the chemical changes in calf thymus DNA samples were analyzed by X-ray photoelectron spectroscopy (XPS). The DNA samples were irradiated for over 5 h and spectra were taken repeatedly every 30 min. In this approach the X-ray beam both damages and probes the samples. In most cases, XPS spectra have complex shapes due to contributions of C, N, and O atoms bonded at several different...
