Abstract Clarifying the principles of proportioning optimization for brittle transparent rock-like specimens with differential fracture structures is crucial visualization study internal and seepage evolution mechanisms in rock masses. This study, utilizing orthogonal experimental methods, uncovers influence mechanisms, extents, patterns by which ratios resin, hardener, accelerator, along freezing duration, impact mechanical characteristics specimens. Notably, it was observed that as...
Abstract In this work, the conduction mechanism and dielectric nonlinearity of undoped Mn-doped Na 0.5 Bi TiO 3 (NBT) films were investigated. The potential in relatively low electric fields should be dominated by hopping rather than typical Ohmic conduction. high field region, is Poole–Frenkel emission Schottky emission. enhancement electrical insulation NBT after Mn doping was shown to result from a decrease oxygen vacancies elevation energy barrier. Furthermore, significant improvements...
In this work, the epitaxial 0.85BaTiO3-0.15Bi(Mg1/2Ti1/2)O3 (BT-BMT) films with large compressive strain were fabricated on SrTiO3 (001). The expansion of unit cell volume and out-of-plane lattice parameter built-in electric field (Ebi) in BT-BMT indicate existence defect dipoles. It was found that polarization breakdown strength can be optimized by defects, respectively. Ultimately, a desirable energy density 90.3 J/cm3 efficiency 62.3% achieved. suggests serve as practical means to...
Abstract Interfaces in oxides are found to possess different properties and can be engineered for modifying local structure of nearby area. In this work, it is reported that the interfaces formed Ba/Zr (BZ)‐doped (K,Na)NbO 3 (KNN) thin films by cycles chemical solution deposition using same precursor solution. films, a novel special cross‐sectional observed with periodic distribution Ba‐rich Zr‐rich layers. The layers exhibit strain, lattice parameters, crystal structure, leading an obvious...
Improvements in the polarization of environmentally-friendly perovskite ferroelectrics have proved to be a challenging task order replace toxic Pb-based counterparts. In contrast common methods by complex chemical composition designs, we formed Mn-inlaid antiphase boundaries Mn-doped (K,Na)NbO
Intrinsic SrTiO 3 is a quantum paraelectric, but moderately Bi-doped exhibits dielectric frequency dispersion similar to relaxor ferroelectrics. In this paper, detailed electron microscopic studies of the microstructures samples were presented. It was found that Sr sites replaced by off-central Bi, resulting in tensile strain strontium titanate (STO) lattice. samples, valence titanium mainly showed Ti[Formula: see text] characteristic. According behavior and microstructure analysis, polar...
This paper reports an enhanced approach of thermal reduction phosphogypsum (PG) in the presence sodium chloride (NaCl) its molten phase. The thermodynamic together with in-situ thermogravimetric-Fourier transform infrared spectroscopy (TG-FTIR) result indicates yield CaS (solid) at investigated temperature range (800-850 °C). Addition NaCl not only appreciably reduces activation energy this reaction °C) on average from 315 to 175 (kJ·mol-1) materially, but also significantly improve...
Three types of dissociated misfit dislocations (MDs) in epitaxial Ba0.3Sr0.7TiO3 thin films grown on (001) LaAlO3 have been studied by high-resolution transmission electron microscopy. First, a MD with b=[101] dissociates into two edge partials and results the incline film lattice. Second, [110] is split (1/2)[110] mixed character. In third case, character composed three which are reacted (1/2)⟨110⟩ stacking faults. Neither dissociation reactions has reported before for MDs perovskite films.
<title>Abstract</title> Improvements in the polarization of environmentally-friendly perovskite ferroelectrics have proved to be a challenging task. In contrast traditional methods by complex chemical composition designs, we successfully formed new Mn-inlaid antiphase boundaries Mn-doped (K,Na)NbO<sub>3 </sub>thin films using pulsed laser deposition method. Mono- or bi-atomic layer Mn has been identified inlay along balance charges originated from deficiency alkali ions and induce...
Abstract To clarify the torsional deformation performance of 3D angle‐interlock woven preforms, this paper aims to establish relationship between structural parameters and fabrics, examining mechanism fabrics. The properties fabrics are first characterized by experimental methods, influence laws typical on obtained. In continuing, a numerical model for fabric is established based virtual fiber modeling technology. demonstrate accurateness newly developed model, its results methodically...
