The electrical conductivity of KMgFe(MoO4)3 crystals has been determined in the temperature range 296–828 K using impedance spectroscopy (5 to 5 × 105 Hz). The potassium magnesium iron molybdate was prepared by solid-state reaction between MgMoO4 and KFe(MoO4)2 at 900 ± 25 K over a period of 200 h. The ionic conductiv…
Abstract Zn‐doped NiO thin films were prepared by sol‐gel spin‐coating method onto transparent conducting substrates using nickel acetate tetrahydrate and zinc acetate dehydrate as starting precursors. Effects of zinc doping content on the structural, optical and electrochromic properties of NiO films were investigate…
Abstract The heptacoordinate transition metal coordination compound [Cd(SCZ) 3 (H 2 O)](PA) 2 · 3H 2 O ( 1 ) with the ligand semicarbazide (SCZ) and the counteranion picrate (PA) was synthesized and characterized by elemental analysis and FTIR spectroscopy. Single‐crystal X‐ray diffraction analysis revealed that 1 cry…
The temperature evolution of the electronic structure of a Ni-Fe(Co)-Ga/MgO(100), Heusler-type, ferromagnetic shape-memory alloy thin film has been followed by a bulk-sensitive hard x-ray photoelectron spectroscopy, element-selective soft x-ray magnetic circular dichroism, and first-principles calculation. The reversi…
We formulate and analyze an optimization-based Atomistic-to-Continuum (AtC) coupling method for problems with point defects. Application of a potential-based atomistic model near the defect core enables accurate simulation of the defect. Away from the core, where site energies become nearly independent of the lattice…
Tripolar cups can be separated into constrained and unconstrained dual-mobility cups. The latter show better survival and revision rates. The main problem is the polyethylene wear. Therefore modern types of polyethylene are used in these cups. The indications for dual-mobility cups are recurrent dislocation and situat…
Abstract The paper aims at the investigation of atmospheric pressure weakly ionized plasmas with argon and acetylene to deposit plasma-polymerized coatings on wood veneers (birch, maple), cellulose paper, and pine wood flour to modify their surface properties, in particular their topography and wettability. The treatm…
<div class="section abstract"><div class="htmlview paragraph">Thermoelectric generators (TEGs) can be used for a variety of applications in automobiles. There is a lot of interest in using them for waste heat recovery from a fuel economy point of view. This paper examines the potential of TEGs to provide c…
<div class="section abstract"><div class="htmlview paragraph">An accurate model to predict the formation of fogging and defogging which occurs for low windshield temperatures is helpful for designing the air-conditioning system in a car. Using a multiphase flow approach and additional user-defined function…
The annealing effect on the thermoluminescence (TL) characteristics of x-ray irradiated muscovite mineral relevant to dosimetry has been studied. For un-annealed and 473 K annealed samples an isolated TL peak has been observed at around 347 K; however, annealing at 573, 673 and 773 K two composite peaks have been reco…
Abstract Thermal analysis was applied to determine the liquidus temperatures in the NaCl–KCl–BaCl 2 –BaO system, with BaO concentration varied from 0 to 6 mole%. The temperature dependence of the BaO solubility in the NaCl–KCl–BaCl 2 eutectic melt was investigated; the thermodynamic parameters of BaO dissolution were…
This work introduces metallo-dielectric woven fabric as a metamaterial for phase-front manipulation. Dispersion diagram as well as effective medium parameters retrieved from reflection and transmission coefficients point out negative values of refractive index. By numerical simulations, it is evidenced that a pair of…
This paper reports the effect of sintering temperature on the structural, optical and ferroelectric properties of vanadium (V) doped zinc oxide (ZnO) samples. X-ray diffraction (XRD) study confirms the formation of a hexagonal wurtzite phase. It has been found that the increase in sintering temperature leads to very s…
Optical and magneto-optical properties of single crystal of Ni50.1Mn28.4Ga21.5 magnetic shape memory alloy during its transformation from martensite to austenite phase were systematically studied. Crystal orientation was approximately along {100} planes of parent cubic austenite. X-ray reciprocal mapping confirmed mod…
Abstract In this work, the 1–3 connectivity piezoelectric ceramic–polymer composites have been fabricated by a viscous-polymer processing, where 0.90Pb(Zr 0.52 Ti 0.48 )O 3 –0.05Pb(Mn 1/3 Sb 2/3 )O 3 –0.05Pb(Zn 1/3 Nb 2/3 )O 3 (PZT–PMS–PZN) fibers with 0.5 volume fraction were aligned in epoxy matrix. The sintered PZT…
Abstract Complex cationic‐anionic ordering in barium‐based oxygen deficient perovskites is reviewed. Considering the parent AB O 3 structure, the ordering between barium and a rare earth cation in the A site generates three classes of oxides, called double, triple and nanoscale ordered quintuple perovskites. From the…
ZnO/Zn x Cd1-x Se coaxial nanowires (NWs) have been successfully synthesized by combining chemical vapor deposition with a facile alternant physical deposition method. The shell composition x can be precisely tuned in the whole region (0 ≤ x ≤ 1) by adjusting growth time ratio of ZnSe to CdSe. As a result, the effecti…
