A calcium strontium barium niobate (Ca0.28Ba0.72)0.25(Sr0.60Ba0.40)0.75Nb2O6 (CSBN25) single crystal has been grown using the Czochralski technique. The point group and space group of CSBN25 were determined by x-ray powder diffraction analysis to be tetragonal 4 mm and P4bm, respectively. The complete set of dielectri…
Small-angle neutron scattering with polarization analysis reveals that Fe3O4 nanoparticles with 90 Å diameters have ferrimagnetic moments significantly reduced from that of bulk Fe3O4 at 10 K, nominal saturation. Combined with previous results for an equivalent applied field at 200 K, a core-disordered shell picture o…
The collapse of transient bubble clouds near a solid surface was investigated to test a scheme for mitigation of cavitation-induced damage. The target was a porous ceramic disk through which air could be forced. Transient cavitation bubbles were created using a shock-wave lithotripter focused on the surface of the dis…
The conductivity and ion and proton transfer numbers were measured in La1 − x Sr x Sc1 − y Mg y O3 − α system (x = y = 0.10–0.20). The partial conductivities (total ion, proton, oxygen, hole) and their effective activation energies were calculated. The measurements were carried out in air with respect to humidity (pH2…
Samples of the CAB-1 alloy in the initial state and irradiated with fast neutrons at an fluence of 2 × 10 21 neutrons/cm 2 have been studied by small-angle neutron scattering. It has been demonstrated that the observed large scattering cross sections are associated with the presence of nanosized pores with radii R ∼ 5…
Single-phase samples of A 3 TeO 6 (A—Mn, Co, Ni) oxides and solid solutions in a (Mn 1-x B x ) 3 TeO 6 , B—Co, Cd system belonging to the structural series of magnesium orthotellurate were obtained by solid-phase synthesis. The temperature behavior of the ceramics’ magnetization, thermal capacity, and dielectric prope…
The surface of palm kernel was modified by acrylic acid (AA). Low density polyethylene (LDPE) was filled by palm kernel shell at various 0, 10, 20, 30 and 40 php. The effect of AA as a coupling agent on LDPE/PKS biocomposites on tensile properties and morphology was investigated. The results show that the increasing o…
Abstract The influence of alloying elements, including rhenium and ruthenium, on the physicochemical and structural parameters of single crystal nickel-base superalloys has been analyzed. The results were used in computer designing of a single crystal nickel-base superalloy containing rhenium and ruthenium. The optimi…
Abstract We describe here a strategy for the synthesis of HyperMacs – long‐chain branched analogues of hyperbranched polymers. The building blocks for HyperMacs, AB 2 macromonomers, are synthesized by living anionic polymerization and, as such, are well‐defined in terms of molecular weight (MW) and polydispersity. Siz…
The influence of Pr content on structure, magnetic properties, and magnetic entropy changes of La1−xPrxFe11.44Si1.56 was investigated. X-ray diffraction analysis showed that the 1:13 phase with cubic NaZn13-type structure was obtained by a short time annealing (1300 K and 3 h) in melt-spun ribbons, which in contrast r…
Using the highly precise full-potential linearized augmented plane-wave method, magnetostriction of ferromagnetic shape memory alloy Fe3Pt in the cubic L12 structure is investigated. Being consistent with experiments, the giant magnetostrictive coefficient (λ001) of −1050 ppm was calculated from strain-induced magneto…
An efficient and convenient method for degradation of Acid orange 3 (A03) dye from aqueous solution by combination of Fly ash/H 2 O 2 and ultrasound irradiation is reported. The effects of the relevant operating conditions (pH value, dye concentration, H 2 O 2 concentration, dosage of Fly ash and different reaction sy…
Two systems of noncentrosymmetric cubic helical magnets Mn1 − y Fe y Si (y = 0.06, 0.08, 0.10) and Fe1 − x Co x Si (x = 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.50) have been compared. The concentration dependences of the critical temperature and magnetic field have been obtained using small-angle polarized-neutron scatt…
This paper provides an investigation of the phase transition and spalling characteristic induced during shock loading and unloading in the pure iron and the FeMnNi alloy. The impact for the pure iron is symmetric and with the same-thickness for both the flyer and the target plate. It is found that an abnormal multiple…
Abstract Magnesium hydroxide, which is a weak alkali, can be used as the alkali source for peroxide bleaching of mechanical pulps. This magnesium hydroxide-based peroxide bleaching process has been commercialized in the paper industry. In this paper, we review the literature results regarding the process chemistry of…
Abstract An inorganic dominated silica/polyimide (PI) hybrid film has been successfully developed for the fabrication of flexible AM‐OLED. The inorganic‐organic hybrid film was achieved in roll type with a variety of attractive properties such as low coefficient of thermal expansion (CTE, 33 ppm/°C), high transmittanc…
Abstract For the first time, we have developed a 60‐inch diagonal size see‐ through display using polymer network liquid crystal (PNLC) technology. The color display system by combination of the see‐ through display and a projector enables distinguishing eye‐catch effect. It creates new application of displays, such a…
BACKGROUND: Quantum dots (QDs) are crystalline nanoparticles that are compatible with biological systems to provide a chemically and photochemically stable fluorescent label. New ligand probes with fluorescent reporter groups are needed for detection and characterization of G protein-coupled receptors (GPCRs). RESULTS…
A comprehensive analysis is presented of the effects of surface diffusional anisotropy on the morphological stability of planar surfaces of stressed crystalline solids under the simultaneous action of an electric field. The analysis is based on self-consistent dynamical simulations of driven surface morphological evol…
