To enhance the frictional wear performance of AZ31B magnesium alloy, a nanocrystalline layer was prepared by ultrasonic impact (UI) treatment on alloy samples, and effects different times (5 min, 10 15 min) organization resistance composite coating were studied. The findings revealed that maximum thickness about 50 μm after min time, which approximately higher than MAO coating. elemental compos...

Activation of micro-opioid receptors makes animals hyperphagic and increases their preference for a high-fat diet. Previous studies have suggested that this receptor population plays a role in mediating the hyperphagia that is associated with food deprivation. In this paper, we tested the hypothesis that food deprivation will increase the expression of micro-opioid receptors in the ventral medi...

Owing to their combination of high hardness and increased fracture toughness, CrTaN coatings have recently gained increasing interest as suitable candidates for metal cutting applications. However, up now, the detailed mechanisms underlying oxidation this promising coating system are not thoroughly understood. Thus within work, evolution microstructure phase composition a cathodic arc evaporate...

metal—polyaniline nanocomposites such as platinum-polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of pt+4 ions into pt nanoparticles. thepolymerization of aniline was carried out in the presence of 1(2ptcn6 [potassium hexa cyanoplatinate (iv)] as oxidizing agent. during the reaction aniline monomers undergo oxidation andform polyaniline (pant) w...

Equal channel angular pressing results in ultrafine-grained (approximately 200-500 nm) Ti with superior mechanical properties without harmful alloying elements, which benefits medical implants. To further improve the bioactivity of Ti surfaces, Ca/P-containing porous titania coatings were prepared on ultrafine-grained and coarse-grained Ti by micro-arc oxidation (MAO). The phase identification,...

Object: This paper aims to evaluate the influence of dental implants coated with hydroxyapatite (HA) and implants processed by micro-arc oxidation (MAO) coupling electrophoresis deposition (EPD) on experimental peri-implantitis in Beagle dogs. Methods: The thirty-six implants (diameter 3.3 mm & length 11 mm) were equally divided into three groups. Group A was processed with a plasma-sprayed lay...
