As an alternative to chromate conversion coatings, rare-earth coatings especially cerium, because of the low toxicity, have attracted considerable attention. Using dip immersion method, cerium-based conversion coating was deposited on aluminum 2024. Corrosion resistance was studied in 3.5 wt.% NaCl solution using potentiodynamic polarization, electrochemical impedance spectroscopy, and surface ...

introduction one of the limitations of tissue conditioners (tc) is gradual hardening of the material in a short time period after insertion in the mouth, due to the loss of their viscoelastic properties. the aim of this study was to determine the softness of two different tissue conditioners with and without the monopoly coating. methods and materials in this experimental study, acropars and vi...

Highly transparent and luminescent CaMoO4:Eu/Ag composite films were fabricated on glass substrates as multifunctional antireflective (AR) coatings. The films were deposited through a combination of a sol–gel dip-coating technique and a hot water treatment. With the addition of an aluminum source in coating solutions, the sol–gel-derived films underwent a remarkable microstructural change durin...

Copper oxide (Cu2O)-based heterojunction solar cells were fabricated by spin-coating and electrodeposition methods, and photovoltaic properties and microstructures were investigated. Zinc oxide (ZnO) and Cu2O were used as nand p-type semiconductors, respectively, to fabricate photovoltaic devices based on In-doped tin oxide/ZnO/Cu2O/Au heterojunction structures. Short-circuit current and fill f...

Lithium aluminum hydride (LiAlH4) is an interesting high capacity hydrogen storage material with fast hydrogen release kinetics when mechanically activated with additives. Herein, we report on a novel approach to produce nanoscale LiAlH4 via a bottom-up synthesis. Upon further coating of these nanoparticles with Ti, the composite nanomaterial was found to decompose at 120 ◦C in one single and e...

Abstract: In this paper, we present the synthesis of Fe3O4 nano particles of hybrid for coating on metal or glass surfaces.The synthesis of the organic/inorganic nanocomposite is described. This nanocomposite is a water – dispersible polymeric complex of polymethacrylic acid and polyaniline.The water dispersible hybride material was coated on aluminum using a molecular layer – by – layer coatin...
