The initial stages of growth of zirconia nanoparticles deposited on SiO2, Y2O3, and CeO2 substrates have been studied by the x-ray photoelectron spectroscopy peak shape analysis. ZrO2 was deposited by plasma decomposition of a volatile Zr OtBu 4 precursor. The electronic interactions at each particular interface formed have been followed by means of the modified Auger parameter of the deposited...

CuO nanoparticle was found to be an efficient catalyst for the synthesis of flavanones derivatives from the reactions between 2-hydroxyacetophenones and aromatic aldehydes at room temperature. The protocol offers advantages in terms of higher yields, short reaction times, and mild reaction conditions, with reusability of the catalyst. The structures of the synthesized substituted flavanones wer...

Mineral trioxide aggregate (MTA) and Portland cement (PC) are calcium silicate cements. They have similar physicochemical, mechanical and biological properties. The addition of zirconium oxide (ZrO2) to PC provides radiopacity. Silver nanoparticles (AgNPs) may improve some properties of cements. The aim of this study was to evaluate the effect of AgNPs on physicochemical/mechanical properties a...

Tetragonal zirconia (t-ZrO2) nanoparticles were synthesized from thezirconium chloride using the co-precipitation technique and characterized by variousmeasurement techniques. FESEM analysis further revealed spherical shaped NPs andHR-TEM analysis determined the size of the particles in the range of 14.5 nm. The bandgap energy was estimated 4.0 eV. The UV (350 nm) emissi...

BACKGROUND The purpose of this in-vitro study was to examine the effect of incorporating different concentrations of Zirconium oxide-Titanium dioxide (ZrO2-TiO2) nanoparticles, which can have antibacterial properties, on the mechanical properties of an orthodontic adhesive. METHODS ZrO2-TiO2 (Zirconium oxide, HWNANO, Hongwu International Group Ltd, China) -Titanium dioxide, Nanoshell, USA) na...

Catalyst stability in the liquid phase under polar conditions, typically required for the catalytic conversion of renewable platform molecules, is a major concern but has been only sparsely studied. Here, the activity, selectivity, and stability of Ru-based catalysts supported on TiO2, ZrO2, and C in the conversion of levulinic acid (LA) to γ-valerolactone (GVL) has been studied at 30 bar of H2...

The suggested polybenzoxine@ZrO2 nanocomposite surfaces' excellent anticorrosive feature opens in novel avenues for the creation of high action non-corrosive coatings variety sectors. conclusion mild steel was decreased as a consequence accumulation PBz-wrapped ZrO2 nanoparticles to PU coating because they prevented charge transfer at metal/electrolyte interface. TGA proves that copolymer matri...

The synthesis, structure and mechanical properties of inorganic organic nanocomposites are investigated: The systems consist of an aliphatic amine cured Bisphenol-F-based epoxy resin as organic matrix and SiO2 and ZrO2 nanoparticles as inorganic fillers. Silica and zirconia nanoparticles have been prepared in two different size ranges, one in the upper nano range (30-60 nm) and other in the low...

One-dimensional (1D) metal oxide nanomaterials, such as zinc oxide (ZnO) nanowires and nanobelts (or nanoribbons), have recently attracted immense attention due to their sizeand shape-dependent optical, mechanical, and electronic properties. In stark contrast, investigations of 1D zirconia (ZrO2) and hafnia (HfO2) nanomaterials remain unexploited largely because of the formidable challenges ass...
