The presence of pathogenic microorganisms in wastewater and their resistant nature to antibiotics impose effective disinfection treatment for public health and environmental protection. In this work, photocatalysis with metal-doped titania under artificial and natural sunlight, chlorination and UV-C irradiation were evaluated for their potential to(More)
In this work, structural and optical properties of vanadium oxides have been presented. Thin films were manufactured by microwave-assisted magnetron sputtering process. Particles were sputtered from a vanadium target in Ar/O2 atmosphere. Oxygen partial pressure was changing from 3×10–4 to 7×10–4 Torr. After the deposition, the thin films were additionally(More)
The life cycle assessment of several zinc oxide (ZnO) nanostructures, fabricated by a facile microwave technique, is presented. Key synthesis parameters such as annealing temperature, varied from 90°C to 220°C, and microwave power, varied from 110W to 710W, are assessed. The effect of these parameters on both the structural characteristics and the(More)
Klebsiella pneumoniae is considered to be an emerging pathogen persisting under extreme environmentally stressed conditions. The aim of the present study is the investigation of inactivation rates of this pathogen in water by means of heterogeneous photocatalytic treatment under solar irradiation and the induced genetic variance applying RAPD-PCR as a(More)
In2O3-x thin films with a thickness of 100-990 nm were grown by dc magnetron sputtering. Their structural, electrical and ozone sensing properties were analyzed. Structural investigations carried out by electron probe micro analysis, secondary ion mass spectrometry and atomic force microscopy showed a strong correlation between stoichiometry, surface(More)
Single layers of MgF2 and LaF3 were deposited upon superpolished fused-silica and CaF2 substrates by ion-beam sputtering (IBS) as well as by boat and electron beam (e-beam) evaporation and were characterized by a variety of complementary analytical techniques. Besides undergoing photometric and ellipsometric inspection, the samples were investigated at 193(More)
We report on a test standard for different microscopic techniques combined onto one substrate. The patterns of the test standard are recognizable by image processing routines to provide robotic navigation inside Scanning Electron Microscopes. Here it can be used for high-resolution and astigmatism testing. In the center of this standard is a pattern of(More)
CoxNi1-xTiO3 systems evaluated as photo- and electrocatalytic materials for oxygen evolution reaction (OER) from water have been studied. These materials have shown promising properties for this half-reaction both under (unbiased) visible-light photocatalytic approach in the presence of an electron scavenger and as electrocatalysts in dark conditions in(More)
