X-ray photoelectron spectroscopy was employed to study the thermal diffusion of iron, nickel and cobalt through gold in bilayer thin film structures under an oxidizing environment. The data suggest that the driving force for the diffusion is the oxidation of the transition metal at the surface. ...
XPS(X-ray Photoelectron Spectroscopy)是一种表面分析技术,它通过照射样品表面的X射线,利用光电子能谱仪来研究样品表面的化学成分和电子状态。XPS分析原理主要包括激发过程、光电子的逃逸和能谱的测定三个方面。 首先,我们来看激发过程。在XPS分析中,样品表面受到X射线的照射后,原子内部的电子会被激发到较高的能级。

X-ray photoelectron spectra of polyaniline (PANI) doped by molybdophosphoric, tungstophosphoric and tungstosilicic acids were measured and discussed. Three different nitrogen species (imine, amine and protonated) were distinguished, and their proportions were determined. The N(1s) binding energies of...

These phases were subsequently analysed by x-ray photoelectron spectroscopy (XPS). Well defined trends were observed in all of the spectra recorded. These data have been used to cha- racterise the different phases and to exemplify changes in structure with varying compo- sition....
Alumina-doped silica gels used as catalysts for a new pyridine synthesis from cyclopentadiene and ammonia have been investigated using X-ray photoelectron spectroscopy. Two different types of aluminum species are identified. Their chemical nature is assigned to a "normal" Al oxide and a more ...
Differences between the surface chemistry of Scots pine samples, which were friction densified or compressed in a heated press without motion, have been evaluated by means of X-ray photoelectron spectroscopy (XPS). On the surfaces of friction densified sapwood, a thin and even layer of extractive...
X-Ray Photoelectron Spectroscopy (XPS) is a powerful surface analysis technique able to detect every chemical element present, being also sensitive to their chemical environment. Here we explore the use of XPS as a fast technique to characterize EV membrane composition, with possible application in ...
