Highly efficient bacteria inactivation and phenol degradation by visible light irradiated iodine doped TiO2

László Forró, Andrzej Sienkiewicz, Klara Hernadi

In this study visible light active iodine doped titanium dioxide samples prepared by sol-gel method were investigated. Photocatalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray fluorescence spectroscopy (XF ...

Surface structure of nickel oxide layers on a Rh(111) surface

Luca Gragnaniello

The formation of nickel oxide nanolayers by oxidizing Ni overlayers on Rh(111) has been investigated and their structures are reported as a function of the nickel coverage and oxygen pressure. Scanning tunneling microscopy (STM), low-energy electron diffra ...

Origin of fine structure in Si 2p photoelectron spectra at silicon surfaces and interfaces

Alfredo Pasquarello, Oleg Yazyev

Using a first-principles approach, we investigate the origin of the fine structure in Si 2p photoelectron spectra at the Si(100)-(2x1) surface and at the Si(100)-SiO2 interface. Calculated and measured shifts show very good agreement for both systems. By u ...
