Short-range (SR) magnetic orders such as glass or fluctuations in a quantum system usually host exotic states critical behaviors. Like the long-range (LR) orders, SR can also break time-reversal symmetry and drive nonzero Berry curvature leading to novel transport properties. In this work, we report that $\mathrm{Eu}{\mathrm{Zn}}_{2}{\mathrm{As}}_{2}$ compound, besides LR $A$-type antiferromagnetic (AF) order, order is observed wide temperature region. Magnetization measurements electron...
${\mathrm{Sr}}_{2}{\mathrm{CuTeO}}_{6}$ is a square-lattice N\'eel antiferromagnet with superexchange between first-neighbor $S=1/2$ Cu spins mediated by plaquette centered Te ions. Substituting W, the affected impurity plaquettes have predominantly second-neighbor interactions, thus causing local magnetic frustration. Here we report study of ${\mathrm{Sr}}_{2}{\mathrm{CuTe}}_{1\ensuremath{-}x}{\mathrm{W}}_{x}{\mathrm{O}}_{6}$ using neutron diffraction and $\ensuremath{\mu}\mathrm{SR}$...
Abstract Halide perovskites emerge as promising candidates for thermoelectrics due to their ultralow thermal conductivity. The conventional theory based on the phonon gas model, which treats transport particle‐like behavior, shows limitations describe unusual property in some halide with strong anharmonicity. Here, significance of coherence effect bismuth‐halide perovskite Cs 3 Bi 2 Br 9 is reported by inelastic neutron scattering and simulations including density functional machine‐learning...
We propose an improved method to design freeform reflectors for architectural lighting: one accent lighting and another large area wall washing. The designed effectively distribute light fluxes over the target surfaces, generate appropriate illumination patterns comfortable visual environments, which provides greater flexibility designs, allows many challenging improves energy-efficiency simultaneously.
Abstract Sewage and sludge are usually treated separately. Considering improving treatment while sewage is beneficial to the synergetic effect of treatment. The efficiency pulverized coal‐activated (PAS) on contaminant removal, calorific value, combustion characteristic was investigated in contrast conventional activated (CAS) using laboratory‐scale sequencing batch reactor (SBR). Results indicated that average chemical oxygen demand, ammonium nitrogen, total phosphorus removal PAS were...
The high-resolution stress and texture neutron diffractometer HETU at the China Mianyang Research Reactor is dedicated to measuring analysing residual of engineering materials. instrument can provide a high resolution flux sample position. This article presents optics design based on Monte Carlo simulation first assessment its experimental performance. technical parameters monochromators, slit system, radial collimators detector were determined. A double-focusing silicon monochromator with...
A novel curved compound eye imaging system is put forward in this paper. Non-uniform hexagonal lens array arranged on the inner surface of a plano-concave substrate. Based geometrical optics, parameters each microlens are set according to position lens, and even orders aspheric used correct some primary aberrations. Optical configuration entered into numerical ray-tracing simulations (ZEMAX). The result shows that new can enlarge field view (FOV) approximately 50% compared lateral eye, FOV...
Plasticized polymer gel has emerged as a new material for the fabrication of microlenses with variable focal lengths. To explore non-toxic and non-irritating gel, we prepared polyvinyl alcohol (PVA)/glycerol which is sensitive to external direct-current (DC) voltage exhibits strong polarization effect upon application an electric field. Due effect, PVA/glycerol bends toward cathode like polyelectrolyte gel. fabricate microlens array, was spin-coated on glass substrate diamond Indium Tin...
We designed freeform reflectors for architectural lighting applications. Compared with conventional luminaries, these luminaries can effectively distribute light fluxes over target surfaces, and generate appropriate illumination patterns comfortable environments.
