The Mössbauer spectra of a FeSe0.3Te0.7 single crystal grown by the Bridgman method were analysed across the superconducting transition by considering the interplay between the structure and electron configuration of the transition metal. The magnetically determined superconducting critical temperature is TC ∼ 14 K. T…
The PbS nanoparticles (PbS1 and PbS2) have been prepared by a facile solvothermal method, using bis(N-benzyl-N-furfuryldithiocarbamato-S,S′)lead(II) (1) and bis(N,N-difurfuryldithiocarbamato-S,S′)l...
In this study, we measured the mass attenuation coefficient of n-type GaAs, p-type GaAs, n-type Si and Au/n-Si/n+Si/Al samples with and without external electric field. Samples were set in perpendicular direction to the 100 mCi 241Am radioactive source and counts were made with a NaI(Tl) detector. It was observed that…
Several treatments are applied to reduce or remove oxygen from packages and In contact with foods, aiming shelf-life extending. Metallic iron has been used as oxygen absorber agent in foods systems. This study aimed evaluates the action of iron nano-particles cellulosic matrix films on in vitro inhibition of Aspergill…
The method of determination of speed of polymerization on initial and middle stages of process with the use of special one dilatometers for systems with high viscidity is developed. The methods of calculation thermophysical parameters for determinations possible volumes probed oligomerous systems was offered.
Metal silicides comprise a large family of refractory intermetallic materials that have diverse physical properties and many applications, including complementary metal-oxide-semiconductor (CMOS) devices, thin film coatings, bulk structural components, electrical heating elements, thermoelectric, and solar energy conv…
Abstract Polyamide 11 (PA 11)/polyamide 12 (PA 12) blends with and without liquid polybutadiene (LB) containing isocyanate end groups (LBD) were prepared in the Brabender plastograph. The rubber was added in order to increase the impact strength of the polyamides. Tensile strength and elongation at the upper yield poi…
We report the fabrication and characterization of highly responsive ZnMgO-based ultraviolet (UV) photodetectors in the metal–semiconductor–metal (MSM) configuration for solar-blind/visible-blind optoelectronic application. MSM devices were fabricated from wurtzite Zn1–xMgx O/ZnO (x ∼ 0.44) thin-film heterostructures g…
As the world's population grows and modernizes, developing inexpensive and efficient technologies for solar energy conversion is becoming increasingly important. Photovoltaics and artificial photosynthesis are two approaches for transforming solar energy into a usable form, either electricity or chemical fuels. While…
A novel ordered macroporous polycysteine/Cu composite film (DOM PCE/Cu) was successfully prepared by electrochemical deposition method using polystyrene spheres as templates on a bare glassy carbon electrode (GCE). The structure and electrochemical properties of DOM PCE/Cu film were characterized. The DOM PCE/Cu compo…
In the field of energetics and renewable energy sources, fertilizers, remediation and recultivation, waste management and other, biomass is widely studied and used these days. Determining the mineral phases present in the biomass is essential for determining the binding of chemical elements from which further derives…
One end open V(n)Bz(n)(-) (n = 1-5; Bz = benzene) and both ends open V(n)Bz(n-1)(-) (n = 2-5) vanadium-benzene cluster anions were studied using anion photoelectron spectroscopy and density functional calculations. The smaller (n ≤ 3) V(n)Bz(n) and V(n)Bz(n-1) clusters and corresponding anions were found to have struc…
A new series of hydrazide derivatives of N,N-bis(3,4,5-tris(heptyloxy)benzoyl) (T7 series) were designed and synthesised. Investigations on the liquid crystalline properties by differential scanning calorimetry (DSC), wide-angle X-ray diffraction (WAXD) and polarising optical microscopy (POM) showed that the di-hydraz…

For many accelerator magnets field quality at the bore is a critical requirement for which reason it is necessary to fully characterize the persistent-current magnetization of strands of the kind under consideration for these magnets. The magnetization of a strand is generally measured in a magnetometer. However, cert…
Abstract A tetranuclear neutral MRI contrast agent, (Gd‐DO3A)4‐TPM, was designed and synthesized by appending four Gd‐DO3A moieties upon the tetraphenylmethane derivatives. The longitudinal relaxivity of (Gd‐DO3A)4‐TPM measured at 20 MHz, 37 °C and pH 7.0 is 6.8 mM–1·s–1 per Gd atom, which is one‐fold higher than that…
Abstract Three diblock copolymers of PCL6k-PLLA2k, PCL6k-PLLA4k, and PCL6k-PLLA6k were prepared and their crystallization behaviors were investigated. The molecular weights of the copolymers calculated from 1 H nuclear magnetic resonance spectra were equivalent to the designed molecular weights. The gel permeation chr…
We demonstrate an optimized fringe-field switching pixel structure to apply negative liquid crystals (nLCs) for high-resolution mobile displays. Pixel transmittance can be improved by applying nLCs, but the driving voltage increases because Δε of the nLC is lower than that of the positive LC (pLC). In spite of applyin…
The friction and wear behaviors of plasma sprayed aluminum–bronze (CuAl) coating sliding against silicon nitride (Si 3 N 4 ) in artificial seawater were investigated and compared with those in pure water and dry sliding. The morphologies of the worn surfaces were analyzed by three‐dimensional non‐contact surface mappi…
A novel two‐layer structural thermal barrier coating (TBC) system with a ~150‐µm‐thick CoCrAlY bond coat (BC) and a ~60‐µm‐thick yttria stabilized zirconia (YSZ) ceramic top coat (TC) was prepared on superalloy K444 matrix using electron beam physical vapor deposition (EB‐PVD). This deposited coating was characterized…
