Aluminium-doped (3%) zinc oxide thin films (AZO) were prepared, using pulsed laser deposition, with varying deposition times. The target was fabricated from compacted aluminium-doped nano-powder produced by sol–gel. had a growth consisting of nanostructures in the form columns sharp ends which, for certain times, resemble nano-flowers or nano-leaves. small spheroid-like particles created during columnar act as seed other AZO needles, resulting appearance lotus-like flowers and even smaller...
Spray pyrolysis was used to deposit indium sulfide (In2S3) films, with or without silver doping. The films are polycrystalline, and the inclusion of Ag in In2S3 structure leads formation a solid solution, crystallite size order tens nanometers. exhibit semiconductive behavior, incorporation an increase charge carrier concentration, enhancing electrical conductivity films. small polaron hopping mechanism, deduced by fittings according double Jonscher variation, explains evolution direct...
Cork is a sustainable natural material widely used as wine stopper. However, some other uses, such wall coverings, flooring, bags and shoes, face UV damage. To mitigate this issue, we explored the deposition of TiO2 ZnO thin films via magnetron sputtering on glass cork substrates. Both displayed uniformity lack any discernible cracks or voids, remained transparent in visible region, offered protection. Thus, blocked light with wavelength up to 310 nm (Eg = 4 eV) 370 3.3 eV), respectively....
Indium sulfide (In2S3) is a promising semiconductor that it known as candidate material for optoelectronic devices and applications owing to its exceptional electrical optical properties. Here, we used the spray pyrolysis process deposit undoped, chlorine doped In2S3 films. Then, as-prepared samples were exposed heat treatment in furnace at 400 °C 1 h. The structural measurements reveal obtained show polycrystalline nature with formation of β-In2S3 cubic structure. Besides, In2O3 appears...
In this study, the surface chemistry and morphology photocatalytic antibacterial potential of pure chlorine (Cl)-doped indium sulfide (In 2 S 3 ) thin films, produced by spray pyrolysis, were analyzed. The root-mean-square roughness seemed not to be affected significantly concentration in three doped films (around 12 nm). affect characteristics analyzed study. samples presented a efficiency higher than 80%, but no correlation with was found. assessed against multidrug-resistant bacteria...
Using spray pyrolysis, silver-doped In2S3 thin films were deposited on pre-heated glass substrates, with varying doping concentrations. Subsequently, these underwent vacuum annealing at 400 °C for a duration of 2 h. A comprehensive study their structural, morphological, and optical properties was conducted, revealing homogeneous, compact, crack-free polycrystalline tetragonal-phase In2S3. Among the set analyzed best parameter values, including crystallite size, dislocation density,...
Biopolymers obtained from renewable resources became the center of public interest by virtue their environmental and commercial advantages. Natural polymers such as starch, almond gum, chitosan arabic gum were investigated to get fully or partially biodegradable dielectric material. Thus, in this article we study material properties cashew gum. This biopolymer is an exudate collected occidental anacardium tree. For investigation, scanning electron microscopy powder thin film showed...
