the surface and interfacial analysis of silicon oxide film on silicon substrate is particularly crucial in the nano-electronic devices. for this purpose, series of experiments have been demonstrated to grow oxide film on si (111) substrate. then these films have been used to study the structure of the film by using x-ray photo emission spectroscopy (xps) technique. the obtained results indicate...

X-ray photoelectron spectroscopy (XPS) has achieved maturity as an analytical technique in the materials community, however made apparent by recent reviews highlighting it's misuse, it is a practice which often misunderstood.

To utilize carbon nanotubes (CNTs) in various commercial and scientific applications, the graphene sheets that comprise CNT surfaces are often modified to tailor properties, such as dispersion. In this article, we provide a critical review of the techniques used to explore the chemical and structural characteristics of CNTs modified by covalent surface modification strategies that involve the d...

Zn nanoparticles were prepared by the inert-gas evaporation technique with induction heating method. Asprepared Zn particles were mixed with Na2S solution. ZnS nanoparticles were synthesized under ultrasonic radiation. They were studied by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV spectrophotometry, and X-ray photoelectron spectrometry (XPS). XRD revealed that the ZnS ...

In situ knowledge of the gas phase around a catalyst is essential to make an accurate correlation between the catalytic activity and surface structure in operando studies. Although ambient pressure X-ray photoelectron spectroscopy (AP-XPS) can provide information on the gas phase as well as the surface structure of a working catalyst, the gas phase detected has not been spatially resolved to da...
