Metallic shape memory alloys present fascinating physical properties such as their super-elastic behavior in austenite phase, which can be exploited for providing a structure with both a self-centering capability and an increased ductility. More or less accurate numerical models have been introduced to model their beh…
The adsorption behavior of hydrogen for synthesized graphitic carbon nitride (g-C3N4) and graphene oxide nanosheets was compared. The structure of the prepared g-C3N4 and graphene oxide samples were studied using TEM, FT-IR spectroscopy and surface area analysis. Textural results of the prepared nanosheets show that t…
Abstract The penetration resistance of “SiC/Ti6Al4V/UHMWPE” composite armor, which involves four different constructions at the same area density, has been designed and presented against 12.7 mm armor piercing (AP) projectiles experimentally. Three armor materials, including silicon carbide (SiC), Ti6Al4V, and ultra-h…
Abstract Avocado seeds have been studied for use as corrosion inhibitors of mild steel in a solution of 0.75 M sulfuric acid. Corrosion inhibition efficiency at a concentration of 10 g / L avocado seed extract (ASE) was obtained at 74.56% with weight loss method and 68.38% with potentiometric polarization method. Corr…
The residual resistivity, Hall effect, and magnetization of Co2YSi (Y = Ti, V, Cr, Mn, Fe, Co, Ni) Heusler alloys were considered at T = 4.2 K and in fields up to 100 kOe. It is shown that as the number of valence electrons z ranges from 26 to 32, significant changes in the residual resistivity ρ0, magnetization Ms, s…
Hyperbolic media are very attractive for the application of light field manipulation due to their unique optical properties. In article number 1801616, Ting Xu and coworkers comprehensively discuss the working principle, realization and practical applications of two types of hyperbolic media, including three-dimension…
Background: Ultrasonic cleaners are used for fine cleaning of medical devices, removing soil from joints, crevices, lumens, and other areas that are difficult to clean using other methods. To accomplish this fine cleaning, ultrasonic cleaners use a process known as cavitation. To understand the function of the cavitat…
The availability of TiC healing agent has been evaluated in low temperature self-healing behavior of Al 2 O 3 based self-healing ceramics. For this purpose, some technical issues to actualize the advanced fiber-reinforced self-healing ceramics containing TiC based interlayer as healing agent were discussed. Especially…
We design and theoretically investigate freestanding gallium nitride (GaN) high contrast grating (HCG) membranes as broadband reflectors operating at the visible wavelengths. Optimization of the grating structural parameters is accomplished by using particle swarm optimization (PSO), and rigorous coupled-wave analysis…
Abstract The coefficient of the absorption of an electromagnetic wave in a two-dimensional superlattice based on graphene, in the presence of a constant electric field for the case of quasi-classically strong electric fields is investigated. The anisotropy of the absorption coefficient is revealed at different orienta…
In this research synthesis and characterization of cellulose and nano cellulose and process run under several conditions to obtain parameters which are belongs to optimizing. Cellulose was extracted from BG 352 rice straw using de-waxing, delignification, hemicellulose and silica removal treatment. Extracted cellulose…
Abstract The electrospray method was used to produce polyvinylpyrrolidone (PVP)/mangosteen pericarp extract (MPE) solids. The concentrations of PVP/MPE were 3 and 4 wt.% in ethanol solvent with the mass ratios of PVP/MPE of 10:0, 8:2, and 6:4 (w/w). The surface morphology of PVP/MPE solids was investigated by an optic…
Abstract Nanocomposites refer to materials with at least one one-dimensional dimension within 100nm of the dispersed phase of the composite. Nanomaterials have a large phase interface area, which have many new physical and chemical properties that macroscopic objects do not have. The research on dispersing nano-partic…
Abstract The quaternary ammonium salt-type tetrameric surfactant with hydrocarbon chain length of 12 was synthesized, and characterized using FT-IR and 1H NMR. The inhibition efficiencies for N80 steel in 20% hydrochloric acid were studied by weight loss, potentiodynamic polarization method, electrochemical impedance…
Abstract The solubilization of a water-insoluble biologically active compound, curcumin, in micelles of amphiphilic antimicrobial agents, such as miramistin, ethonium, and cetalkonium, is investigated, and the thermodynamic characteristics of this process are determined. It has been shown that the sol–gel synthesis of…
Electron beam lithography (EBL) and ion beam lithography (IBL) are extremely promising nanofabrication techniques for building nano-electronic devices due to their outstanding physical and electronic properties.

The application of nanotechnology in healthcare is a driver of biomedical innovation, which could also address unmet medical needs. The number of innovative nanoparticle-enabled medicinal products (NEMPs) being developed has been continually increasing [1], thus challenging both the scientific community and regulators…
SiC-based fibers are sensitive to delayed failure under constant load at high temperatures in air. Static fatigue at intermediate temperatures < 800 °C was attributed to slow crack growth from flaws located at the surface of fibers, driven by the oxidation of free carbon at grain boundaries. The present paper exami…
