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...

This study investigates the performance of nanorefrigerants (R134a-ZrO2) in a domestic refrigerator at concentration 0.2 g/l without changing components. Nanoparticles ZrO2 g/L with particle size 1-10 nm and 140 g R134a have been charged, investigations were carried out. Energy consumption pull-down tests conducted to investigate refrigerator. The parameters like refrigeration capacity, compres...

A hybrid material of polystyrene (PS)–ZrO2 was developed by the sol–gel technique and deposited spin-coating on AM60 AM60–AlN nanocomposite surfaces to enhance corrosion resistance in marine environments. PS–ZrO2 with an average thickness ≈305 ± 20 nm dispersed homogeneously, presenting isolated micro–nano-structure defects air trapped inside, which led increase roughness (≈4 times). The wettab...

The Zirconium and Titanium ceramic materials are used to make PZT (Lead zirconate titanate) piezoelectric composite. In this article, the dioxide (ZrO2) (TiO2) fillers with, ferroelectric polymer PolyVinyliDene fluoride-Tri Fluoro Ethylene (P(VDF-TrFE)) utilized ZrO2/P(VDF-TrFE) TiO2 /P(VDF-TrFE) nano-composite thinfilm for flexible vibration energy harvester application. scanning electron micr...

Introduction and Background: Ceramics are inorganic, nonmetallic materials, such as alumina, beryllia, or glassceramic, whose final characteristics are produced by subjection to high temperatures. Nanomaterials is a rapidly growing area of ceramics [1-3] and can be classified into the following categories: Nano-particles submicron or ultra micron size particles; Nano-fibers – nanometer (nm) siz...

The demand for decreasing CO2-emission and harmful material content of the exhaust gas passenger cars requires improvement entire powertrain including applied lubricants. One possible future engines lubricant can be nano-sized ceramic particles, which provide positive tribological properties also in presence nonmetallic surface materials. This paper presents experimental investigation ZrO2 nano...

a novel complex of cadmium (ii) [cdl0.5(no3)(h2o)](1), l= n,n-bis (o-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by ir, 1hnmr spectroscopy, x-ray powder diffraction (xrd) and scanning electron microscopy (sem). the gray single crystal of compound 1 has...

Binary oxide semiconductors TiO2-ZrO2 and Cu-decorated TiO2-ZrO2 (TiO2-ZrO2-Cu) uniform films were sputtered on polyester (PES). These films were irradiated under low intensity solar simulated light and led to bacterial inactivation in aerobic and anaerobic media as evaluated by CFU-plate counting. But bacterial mineralization was only induced by TiO2-ZrO2-Cu in aerobic media. The highly oxidat...
