Abstract:The physical, mechanical and tribological properties of cast multicomponent high-entropy boron-doped alloys obtained by vacuum-arc melting are studied. It was found that cast multicomponent high-entropy alloys doped with boron have a hardness of 20-30 GPа and a modulus of elasticity of 400-600 GPа. Alloying high-entropy all
Abstract:Introduction: Quinazolinone by–product disclosed various curative characteristics such as analgesic, anti-inflammatory and anticancer activities, as well as antimicrobial activity. These heterocycles are beneficial intermediates in organic synthesis. Methods/Experimental:The compound, 6-bromo,2-(o-aminophenyl)
Abstract:Superconducting materials are currently the subject of interest in modern electronic technologies, especially because they exhibit quantum phenomena on a macroscopic scale. The most evident examples are quantized vortices transporting magnetic flux, which movement determines the macroscopic current carrying phenomena in the

Abstract:Purpose: evaluated the effectiveness of the 3D-SR monomer in comparison with the 10-MDP monomer in bond strength (enamel and dentin), nanofiltration (dentin) with application of conventional and self-conditioning modes, sorption and solubility. Materials and methods Seventy-two molars were randomly divided int
Abstract:Thermal expansion is related to the atomic vibration amplitude. Owing to the anisotropy in the lattice, the amplitude will vary with the crystallographic direction, causing strain in the lattice. The strain caused by thermal expansion induces a force large enough to initiate plastic deformation of the metal at the beginning
Abstract:The synthesis of BaFe12-2xCoxNixO19 (x = 0.5-1.5) at a calcination temperature of 1000°C using the coprecipitation method has been done by varying the concentration of the mixed precursor in order to identify the optimum sample. Barium Hexaferrite powder with 0.5% and 1% Nio-CoO h
Abstract:To improve AZ31 magnesium (Mg) alloy plasticity, semisolid extruding with electromagnetic stirring process was adopted, and then the mechanical properties and microstructure were studied. The melting temperature was 730℃, and the preheat temperature of the die was set as 300℃, and electromagnetic stirring parameters were 6H
Abstract:This paper reports the precipitation of calcium phosphate (CaP) on alkaline hydrothermally treated titanium alloy under ultraviolet (UV) lighting. Urea (NH2CONH2) with different concentrations were added into a simulated body fluid buffered by sodium lactate. CO2 and NH3 gas release during immersion tests were detected. The
Abstract:This paper is to present the design consideration of the adjustable flexible auxetic structure which is used in the soft wearable suit with the multi-layer materials. In order to design a macro-auxetic structure with the elastic flexibilities of the soft wearable suit, it is important to make the auxetic unit cell with the
Abstract:Desert sand has the characteristics of large reserves, high quartz content, small and uniform particle size, low organic content and so on. High performance porous ceramic materials were prepared by particle stacking from Kubuqi desert sand, and the effects of forming pressure, holding time and sintering temperature on phas
