Over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (TFC) membranes. In advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (TFN) membranes. However, in the last generation of TFNs, an ultrathin selective film of nanoparticles is coated...

2014 Measurements of the I-V curves of superconducting thin-film microbridges are reported and used to infer some new results regarding the electrical behavior of these devices. At temperatures well below Tc their behavior is found to be dominated by the effects of self-heating. At low voltages near Tc where heating is not important, it is found that the observed behavior is best understood in ...

The composition of pulsed-laser-deposited Y-Ba-Cu-O and Ba-K-Bi-O thin films is shown to be strongly affected by target conditioning, gas pressure, and targetsubstrate distance. For both compounds, ablation from a freshly sanded target surface results in films with an excess of the more volatile elements. The concentration of these volatile elements in the films decreases until the system reach...

Abstract: Different thickness of Cu2S thin films were prepared by vacuum evaporation under a pressure of 10-6 torr at an evaporation rate of 3Å /sec. Cu2S has direct band gap energy and indirect band gap energy at 1.2eV and 1.8 eV respectively. This paper presents the analysis of structural and optical properties of the Cu2S thin film by X-ray diffractometer (XRD) and UV-Vis-NIR Spectrophotomet...

titanium nitride-copper (tin-cu) nanocomposite films were deposited onto stainless steel substrate using hollow cathode discharge ion plating technique. the influence of cu content in the range of 2-7 at.% on the microstructure, morphology and mechanical properties of deposited films were investigated. structural properties of the films were studied by x-ray diffraction pattern. topography of t...

magnetic properties of cobalt nanostructure thin films" (2009). Faculty Publications from Nebraska Center for Materials and Nanoscience. We report on optical, structural, and magnetic properties of two substantially different cobalt nanostructure thin films deposited at an oblique angle of incidence of 85° away from the substrate normal. Comparison is made between an achiral columnar thin film ...
