The O–H stretching vibrations of hydrogen-bonded glass formers (ethanol and glycerol) are studied by Raman scattering in a temperature range where the liquid state changes from low-viscous to solid. Several characteristic bands exhibiting different temperature behavior can be distinguished in the O–H vibrational spect…
We have developed a test structure for evaluating the quality of Al2O3gate dielectrics grown on graphene for graphene field effect transistors on flexible substrates. The test structure consists of a metal/dielectric/ graphene stack on a PET substrate and requires only one lithography step for the patterning of the to…
Abstract Zr0.99Gd0.01O2, Zr0.98Gd0.01Dy0.01O2 and Zr0.98Gd0.01Yb0.1O2 phosphors were synthesized by Pechini method at 1200 °C for 12 h in air. The phosphors were characterized by using X-ray powder diffraction (XRD), differential thermal analysis/thermal gravimetry (DTA/TG), scanning electron microscopy (SEM) and phot…
We have experimentally studied electron transport in a bilayer graphene (BLG)/layered superconductor NbSe 2 junction encapsulated with hexagonal boron nitride. The junction exhibits nonlinear current-voltage characteristics which strongly depend on the gate voltage around the charge neutrality point (CNP) of the BLG.…
The paper presents the results of developments to create a new composite steel-aluminum material with a diffusion barrier. It is shown that the creation between the aluminum and steel of the diffusion barrier made from the nitrated steel layer makes it possible to significantly increase the heat resistance of the stee…
The aim of this work was to obtain superhydrophobic surfaces in a plasma medium. The experiment was carried out using the PECVD method in two different modes: constant and pulsing. The surface roughness was obtained by applying nanoparticles synthesized in plasma in a mixture of argon and methane. The resulting partic…
Fabrication of hard magnetic thin films is a key issue on the development of new micro electro mechanical systems. As the magnetically hard SmCo thin-films offer excellent intrinsic magnetic properties, such as moderate saturation magnetization, large magnetic anisotropy, and high Curie temperature, they are considere…
Bahan baku dasar karung plastik adalah polipropilena yang kuat terhadap kerusakan yang timbul dari bahan kimia (asam dan basa) maupun fisika (panas, dingin dan tekanan). Bila dibandingkan dengan serat sintesis fiber. Polipropilena lebih kesat dan lebih mengikat bahan. Dengan dasar tersebut, Karung plastik bisa digunak…
In this research, Taguchi method is used (S/N) ratio for measuring the variations in experimental design. Taguchi designs used in converting the multi-performance problem into a single-performance problem for experiments which will are in building (Taguchi (L27) orthogonal array) for carburization operation. The main…
Orthorhombic molybdenum trioxide (MoO3) and monoclinic molybdenum dioxide (MoO2) thin films were prepared using the pulsed laser deposition technique under the oxygen (O2) and Argon (Ar) processing gas atmospheres. The MoO3samples were pulsed laser deposited over a range of deposition temperature, 303K to 873K at 10Hz…
In order to improve the corrosion resistance of magnesium lithium alloy, Mg-14Li alloy with different content of Ca (0, 3, 5, 10wt.%) was prepared with a induction melting furnace. Electrochemical test and corrosion test were carried out in NaCI solution with different Cl - concentrations. The results indicate that th…
Introduction Fish skin is important for life and protection mechanisms. Sturgeon skin also has an economical potential for its leather. Materials and Methods This article is a light microscopy study for knowledge the development of epidermis and dermis in one species of sturgeon (Huso. huso). The fishes from different…
In the present work, a one dimensional numerical study of nanoheat transfer in Metal / Oxide / Semiconductor / Field Effect Transistors (MOSFET) structures has been investigated. Several heat conduction models, such as Fourier, Single Phase lag (SPL) and Double Phase Lag (DPL) models, are developed and solved numerica…
Pristine BiFeO3 (BFO) and Ca doped BiFeO3: Ba nanoparticles (NPs) were synthesized in aqueous solution by sol-gel method with Tartaric Acid as a chelating agent. EDAX measurements confirmed the presence of Ca, Ba in the BiFeO3 host lattice. X-ray diffraction analysis showed that the average grain size of the prepared…
The physical and mechanical behavior of titanium nickelide coil springs of different stiffness is experimentally investigated during thermal cycling through martensitic transformation ranges under a constant tensile force. The springs exhibit a reversible length change by reciprocating movements. In terms of classical…
General patterns of the polarization models of Rayleigh, Preisach, and Jiles–Atherton are found. The limiting dependence of the polarization is confirmed. A way of constructing it based on the energy criterion for domain switching for polycrystalline ferroelectrics with perovskite structure is proposed. Differential e…
Based on the tight binding model, we investigate the low energy bandstructures, edge states, and optical absorptions for the silicene nanoribbons (SiNRs) with different terminations under an in-plane exchange field and/or a perpendicular electric field. We find that the zigzag SiNRs are gapped by the exchange field, b…
In justifying the applicability of the steels for the manufacture of structures operating at low temperatures various methods of temperature control of viscous-brittle transition are widely used. The most physically reasonable, but also the most time consuming is the method of determining the temperature brittle fract…
Hollow carbon materials have received intensive attention for energy storage/conversion applications due to their attractive properties of high conductivity, high surface area, large void and short diffusion pathway. In this work, a novel hollow mesoporous material based on carbide-derived carbon (CDC) is presented. C…
