Orthorhombic α″ phase often forms in Ti alloys through martensite transformation during quenching. Here, we report the formation of orthorhombic α″ phase in a low modulus β-Ti alloy during isothermal ageing. The coexists with α and ω phases, and remains stable for 120 h during ageing at 673 K. The phase is highly cohe…
Monolayer MoS2photodetectors are modeled and simulated by self-consistently solving diffusive transport equations in the presence of light illumination and carrier recombination with the 2-D Poisson equation. The simulated results indicate that very high photoresponsivity (PR) of ~1000 A/W observed in others' experime…
A mixture comprising horseradish peroxidase (HRP), glucose oxidase, and glucose was used to cross-link bovine gelatin via dityrosine formation. Suitable HRP, glucose oxidase, glucose addition levels, and reaction time were studied with single-factor trials, and selected as 100 U, 1 U, 0.025 mmol/g protein, and 3 h, re…
A chitosanase was purified from jelly fig latex by ammonium sulfate fractionation (50-80% saturation) and three successive column chromatography steps. The purified enzyme was almost homogeneous, as determined by SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and gel activity staining. The molecular mass of the enz…
In order to improve the performance of ceramic composite armor it is essential to know the mechanisms during each phase of the projectile–target interaction and their influence on the penetration resistance. Since the view on the crater zone and the tip of a projectile penetrating a ceramic is rapidly getting obscured…
Linear ac transport properties are investigated in a graphene semiconducting nanosystem, with the effect of normal-metal electrodes taken into account. We use a tight-binding approach and ac transport theory to study the dc conductance and ac emittance in normal-metal/graphene (NG) and normal-metal/graphene/normal-met…
Studies was made on the effect of plant extract, Umbrella Thorn ( Acacia tortilis ) with mild steel using gravimetric and electrochemical corrosion techniques in 0.5 M H 2 SO 4 . Scanning electron microscope equipped with energy dispersive spectroscopy (SEM/EDS) was used to analyze the surface morphology of the sample…
Abstract We experimentally studied the effects of the C atom on bandgap E G modulation in two-dimensional (2D) silicon carbon alloys, Si1− Y C Y , fabricated by hot C+ ion implantation into the (100) SOI substrate in a wide range of Y (4 × 10−5 ≤ Y ≤ 0.13), in comparison with the characteristics of 3D silicon carbide…
ZnO transparent conductive films were deposited on glass substrates by sol-gel spin coating method. Taguchi method was used to find the optimal deposition parameters, three influential parameters were selected in this experiment, Concentration of zinc (II) ions. Zn2+, annealing temperature Tr and pre-annealing tempera…
The magnetoelectric (ME) effect has been successfully demonstrated in the potential device applications of energy harvesters, magnetic sensors, current sensors, microwave and millimeter-wave multiferroic devices, miniature antennas, and even medical applications. To further investigate the role of ME effect in rotatio…
Ni and Pt structures evaporated onto a TiO 2 (110) surface premodified with ortho -mercaptobenzoic acid ( o -MBA) were studied using polarization-dependent total reflection fluorescence X-ray absorption fine structure analysis to determine the effects of the premodification on the dispersion of the metal atoms over th…
Silkworm cocoons are multi-layered composite structures comprised of high strength silk fiber and sericin, and their mechanical properties have been naturally selected to protect pupas during metamorphosis from various types of external attacks. The present study attempts to gain a comprehensive understanding of the m…
Bulk CoCr2O4undergoes a transition from paramagnetic to long-range ferrimagnetic phase at Ts(94 K) to a long-range and/or short-range spiral order at Ts(~24 K), and finally shows a lock-in-transition below 15 K. The spiral component induces an electric polarization and also a spontaneous magnetization for which it is…
Through first-principles calculations, we investigate the adsorption of alkaline-earth(AE) metal (Mg/Ca) on carbon doped hexagonal boron nitride (h-BN) sheet, as well as its potential application as a sensor for gas molecules H2, H2O, CO, CO2, O2, and NO. With carbon substitution of nitrogen, Mg and Ca were energetica…
The structural and physical properties for xSrO-(100-x)P2O5 glasses, with x = 30, 35, 40, 45, and 50, were investigated. The amorphous state of samples was verified by X-ray diffraction (XRD). Substitution of P2O5 for SrO in the binary SrO–P2O5 glass decreases the molar volume and increase the density measurements fro…
The suitability of a particular material for use in magnetic devices is determined by the process of magnetization reversal/relaxation, which in turn depends on the magnetic anisotropy. Therefore, designing new ways to control magnetic anisotropy in technologically important materials is highly desirable. Here we show…
Hierarchically well-defined multielectron acceptor–photosensitizer (A n –P) assemblies were prepared by nitroxide-mediated polymerization of a styrenic naphthalene diimide and subsequent decoration of the chain terminus by a [Ru(dqp) 2 ] 2+ photosensitizer (dqp is 2,6-di(quinolin-8-yl)pyridine). In view of a facile mo…
Background: Electrospinning is a modest and real tactic to harvest nanofiber membranes from micrometers to nanometers scale diameters, are useful in modern nanotechnology like biomedical, filtration, defense, catalysis, sensor and energy applications. Wound healing practice is deliberated a constant morphological modi…
Polyurethane foam-based sandwich structures were developed for radar absorbing properties together with load bearing capability. The sandwich construction of radar absorbing structure comprised glass fiber epoxy matrix composite containing carbon black as front face skin, carbon fiber epoxy matrix composite as back fa…
An intermediate phase LaMg 2 NiH 4.6 found for the hydrogenation reaction of the ternary intermetallic compound LaMg 2 Ni to the complex transition-metal hydride LaMg 2 NiH 7 has been investigated experimentally and theoretically. It is known that this reaction induces only minor rearrangement of the host metal atoms,…
