Spin-momentum locking of surface states has attracted great interest in recent years due to envisioned technological applications in the field of spintronics. Normal metal surfaces like W(1 1 0) and Ir(1 1 1) show surface states with energy dispersions and spin-polarization textures, which are reminiscent of topologic…
By the introduction of electron-deficient five-membered heterocycles 1,3,4-oxadiazole (OZ) or 1,3,4-thiadiazole (TZ) moieties, two new A1–D–A2–D-type polymer acceptors containing naphthalene diimide, named PNOZ and PNTZ, are prepared and applied for all-polymer solar cells. Both polymer acceptors possess deeply lowest…
Understanding the interaction of adsorbed or covalently immobilized proteins with solid substrates at the molecular level guides the successful design of functionalized surfaces used in biomedical applications. In this report, neutron reflectometry (NR) was used to characterize the structure of surface-attached antimi…
The effect of various tempers (peak ageing T6, RRA T77, two-step ageing T76, and a novel three-step ageing T76 + T6) on electrochemical corrosion of 7150 Al alloy under three corrosive solutions has been investigated. Electrochemical results and corrosion morphologies show that the resistance to pitting corrosion, int…
The issues of disposal and environmental problems are increased by the generation of bottom ash from the thermal power plants day by day; hence, its recycling is required. The present study aimed to make thermal insulation blocks using as raw material bottom ash and iron ore slime as a binder and to characterize their…
In the present work, hardness and elastic modulus of a titanium nitride coatings prepared on Ti6Al4V by powder immersion reaction-assisted coating (PIRAC) are tested and comparatively studied with a physical vapor deposition (PVD) TiN coating. Surface hardness of the PIRAC coatings is about 11[Formula: see text]GPa, m…
In this study, dynamo-thermo-elastic analysis of a rotating piezoelectric hollow cylinder made of functionally material is presented. Coupled differential quadrature and finite difference methods are used to solve boundary/initial value equations of the problem. Material properties are assumed to be graded in radial d…
This article deals with a possibility of another extension longer lasting addition of coatings of titanium dioxide. The research based on the use of nanoparticles has development at present. Potential of added nanoparticles has large use. Particles of nanosize, i.e. below 100 nm exhibit other properties than larger pa…
High Tc superconductor–ferromagnetic heterostructures constitute an appealing playground to study the interplay between flux vortices and magnetic moments. Here, the capability of a solution‐derived route to grow hybrid YBa2Cu3O7‐ferromagnetic nanocomposite epitaxial thin films from preformed spinel ferrite (MFe2O4, M…
We study Josephson currents between $s$-wave/spin-triplet superconductor junctions by taking into account details of the band structures in ${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}$, such as three conduction bands and spin-orbit interactions in the bulk and at the interface. We assume five superconducting order parameters…
H NMR spectroscopy has attracted much attention in the recent years due to the remarkable spectral resolution improvement by ultrafast magic-angle-spinning (MAS) as well as due to the sensitivity enhancement rendered by proton detection. Although these developments have enabled the investigation of a variety of challe…
Optimization of micellar molecular encapsulation systems, such as drug delivery vehicles, can be achieved through fundamental understanding of block copolymer micelle structure and dynamics. Herein, we present a study of PEO–PCL block copolymer spherical micelles that self-assemble at 1% wt/vol in D 2 O–THF- d 8 mixtu…
ABSTRACT Oxidative conditions of the eye could contribute to retinal cells loss through activating the Fas‐L/Fas pathway. This phenomenon is one of the leading causes of some ocular diseases like age‐related macular degeneration (AMD). By targeting proteins at their mRNA level, microRNAs (miRNAs) can regulate gene exp…
Longevity of tillage tools mainly depends on their parts' material wear resistance and strength. The article summarizes information about steel physically-mechanical and exploitation characteristics that are most useful for soil tillage. The physical properties and the prices of chisels from various companies that are…
The simple and efficient measurement of the light orbital angular momentum (OAM) is essential to both the classical and quantum applications with vortex beams. Here, we study the diffraction pattern in the far field when a vortex beam passes through an arc slit and demonstrate experimentally that a light spot of the d…
Aluminum alloy materials, with their light-weight and low-cost characteristics, are considered to be some of the most suitable materials for use as bipolar plates (BPPs). In this study, a chromium-carbon/nickel-phosphorus (Cr-C/Ni-P) bilayer coating is deposited on aluminum alloy 5052 (AA5052) to improve the corrosion…
In the paper, the changes in some mechanical properties and wear behavior of CuSn10 sintered bronze and MMCs based on this bronze reinforced with composite ultrafine aluminide powders FeAl/15 % Al2O3, NiAl/15 % Al2O3 and Ti-46Al-8Cr are described. It was observed that the presence of aluminides in the MMCs leads to an…
We present detailed Monte Carlo simulations of a simple model of a nematic liquid crystal channel waveguide investigating the effect of an applied electric external field. The simulations are based on the Lebwohl-Lasher lattice spin model with boundary conditions chosen to mimic the homeotropic anchoring appropriate f…
In this Letter, we demonstrate, to the best of our knowledge, the first experimental results of sampled Bragg grating with polarization rotator function. Silicon waveguide is used. Multiple polarization-independent reflection wavelength peaks were obtained.
The two samples of coated LiCoO 2 electrode with different microstructures of Al 2 O 3 coating layer are prepared. The XRD, SEM and TEM results reveal that both Al 2 O 3 coating layers attached on the surface of LiCoO 2 have different uniformity, thickness, morphology and crystallinity. The charge-discharge cycling re…
