Metal Oxide Semiconductor, MOS, solar cells of low cost and stable unit proficiency was established. Solar with sol gel SiO2 deposited by spin coating technique were discussed. The layer is prepared via greener methodology at optimum economic impact as promising sustainable source energy. I–V characteristic the sample cell different time investigated. Photovoltaic performance optical properties...

nanostructured alumina thin films were coated on stainless steel by sol-gel dip coating method. in order to prevent crack formation, al2o3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. effects of calcination temperature and withdrawal speed on structural properties were analyzed using xrd and sem. topography and thickness of coatings were analyzed by ...

We study the coherent spin-polarized transport through a zigzag-edge graphene flake (ZGF), using Hubbard model in the nearest neighbor approximation within the framework of the Green function’s technique and Landauer formalism. The system considered consists of electrode/ (ZGF)/electrode, in which the electrodes are chosen to be armchair nanoribbons. The study was performed for two types of ele...

Abstract Chitin has proven to have a good mechanical and electrical properties be used in making piezoelectric thin films. However, due the restriction solubilizing chitosan many solvents, there is increasing interest exploring of producing Chitosan, compared chitin, can easily solubilized certain dilute acids. Chitosan that been extracted from fungal biomass for fabrication biomaterial There a...

In this paper, we report on a process for fabricating silica nanoparticle monolayer based chemical synthesis and spin-coating. Spherical nanoparticles were synthesized by Stöber method using tetraethylorthosilicate as precursor. Close-packed was realized optimizing the speed of Based analyzing field emission scanning electron microscope (FE-SEM) images, average diameter spheres determined found...

The corrosion protection of mild steel by a newly developed epoxy-based coating system containing inherently conducting nanopolyaniline-clay as a nanoadditive has been studied. Polyaniline-clay anticorrosion nanoadditive (PCNA) was obtained by the direct mixing method of nanopolyaniline (0.03 wt.%) and organo-modified clay (3 wt.%) at atmospheric pressure, and XRD technique was used to study d-...

Magnetic resonance micro-imaging was applied to study water diffusion into resin-modified glass ionomer cement restoration and to evaluate the effect of surface coating over restoration. Two cavities were prepared on the labial surface of extracted teeth and restored with resin-modified glass ionomer cement; one was protected with surface coating and the other was not. Immediately after restora...

Channel waveguides based on a polymer, 6-fluorinated-dianhydride/epoxy, which is actively doped with a Nd complex, Nd(thenoyltrifluoroacetone)(3) 1,10-phenanthroline, are fabricated by a simple and reproducible procedure, spin coating a photodefinable cladding polymer onto a thermally oxidized silicon wafer, photopatterning, backfilling with the active core polymer, and spin coating with an upp...

The purpose of this work is to improve the cytocompatibility and corrosion resistance of magnesium alloy in the hope of preparing a biodegradable medical material. The aminated hydroxyethyl cellulose-induced biomimetic hydroxyapatite coating was successfully prepared on AZ31 magnesium alloy surface with a sol-gel spin coating method and biomimetic mineralization. Potentiodynamic polarization te...
