Nowadays, II – IV group semiconductor thin films have attracted considerable attention from the research community because of their wide range of application in the fabrication of solar cells and other opto-electronic devices. Cadmium zinc sulfide (Zn-CdS) thin films were grown by chemical bath deposition (CBD) technique. X-ray diffraction (XRD) is used to analyze the structure and crystallite ...

In this study, NiTi thin films were deposited on the glass and NaCl substrates by means of magnetron sputtering method. The influence of aging temperature, over the range 300-500 oC, on phase transformation and mechanical properties of the sputtered NiTi thin films were studied by differential scanning calorimetry (DSC) and nano-indentation assay, respectively. The DSC curves showed that the ag...

We have used aqueous dispersions of silver nanowires to prepare thin, flexible, transparent, conducting films. The nanowires are of length and diameter close to 6.5 μm and 85 nm, respectively. At low thickness, the films consist of networks but appear to become bulk-like for mean film thicknesses above ∼160 nm. These films can be very transparent with optical transmittance reaching as high as 9...

Starch is one of the cheapest raw materials which can be used in edible film formation. Due to the fact that it is a natural constituent, its incorporation as a food coating does not involve any health risks, although as a barrier material it has the disadvantage of having poor water vapour barrier properties. This could be improved if different non-polar components are included in the starch m...

For the first time, gliadin films with excellent strength and water stability have been developed without using any crosslinking agents. So far, it has not been possible to obtain water stable gliadin films even after crosslinking. In this research, a novel method of using aqueous urea and ethanol has been developed to obtain highly water stable gliadin films without using crosslinking chemical...

in this work, a tracer study on pore initiation in anodic alumina in oxalic acid was performed. effects of some experimental parameters such as applied electrical potential, electrolyte composition and heat pretreatment were evaluated. electrochemical and morphological experiments were performed using potentiostatic anodizing and scanning electron microscopy (sem) techniques, respectively. effe...

BACKGROUND Many scientific studies have shown that the mere presence of guns can increase aggression, an effect dubbed the "weapons effect." The current research examines a potential source of the weapons effect: guns depicted in top-selling films. METHODS Trained coders identified the presence of violence in each 5-minute film segment for one-half of the top 30 films since 1950 and the prese...

Sol–gel derived (3-aminopropyl)trimethoxysilane–tetramethoxysilane ((CH3O)3SiCH2CH2CH2NH2–Si(OCH3)4) hybrid films are shown to have properties that make the films suitable for DNA microarray applications. The essential characteristics of the films are discussed on the basis of binding of aminated 25-mer oligonucleotide DNA to the films via 1,4-phenylenediisothiocyanate linkering. The binding of...

Irradiation of amorphous a-Se Ag I and a-Se films by linearly polarized He–Neand Arq ion-laser light was shown 70 15 15 to produce polycrystalline films with linear dichroism, the sign of which is determined by the polarization of the light. Photocrystallization of the films was confirmed by direct structural investigations. Thus, a new phenomenon, the effect of light polarization on the photoc...
