Summary: Chemistry provides colorful lives of human being, yet it also brings pollution to nature, which reacts to the people themselves. Therefore, making chemical processes greener is the most important responsibility for responsible chemists. In this work, a novel synthetic technique entitled less solvent solid state reaction (LSR) is employed to synthesize Na2S2O3 center dot 5H2O from the reaction of solids Na2SO3 and S8 in small amount of water for the first time. Thermodynamically, LSR can push the equilibrium caused by solution much more to the direction of producing more products. In this reaction system, both Na2SO3 and Na2S2O3 center dot 5H2O is soluble in water, but sulfur dissolves very little and extremely slowly in water. The results indicated that LSR of stoichiometric Na2SO3, S8 and water produces Na2S2O3 center dot 5H2O almost stoichiometrically in 5 h at 115 degrees C; also, the reaction can be catalyzed by Na2S which allows it finish in 2.5 h at the same temperature.

Summary: The study investigates the reaction between the solid electrolyte Li1.3Al0.3Ti1.7(PO4)(3) (LATP) and the active material LiNi0.6Co0.2Mn0.2O2 (NCM622) in all-ceramic oxide batteries through cosintering, which reveals that elemental diffusion and decomposition reactions occur even at low sintering temperatures, hindering the densification of the composite and the formation of ion-conducting paths between individual particles. Based on the experimental results, a mechanism of the reactions in cosintered LATP and NCM622 oxide composite cathodes is suggested.

Summary: Solid-state electrochemistry is an interdisciplinary field that studies the conductive properties of solids in ionic conducting solid electrolytes and mixed ionic and electronic conducting materials. Solid oxide fuel cells (SOFCs) are an important application in solid-state electrochemistry, with unique electrochemical features. The solid-to-solid contact at the electrode/electrolyte interface is one of the most important features in SOFCs and plays a crucial role in phenomena such as equipotential line shift, constriction effect, and polarization-induced interface formation.

Summary: Positive and negative exchange bias effects are observed in Nd1-xPrxCrO3 (0.00 <= x <= 1.00) polycrystalline samples. The shift of hysteresis loops depends on the concentration of praseodymium. The magnetization temperature dependence reveals a magnetic transition at T approximate to 220 K likely ascribed to the Néel temperature of Cr3+ magnetic moments. The Pr-doping has a significant impact on the magnetic properties of the compound.

Summary: In recent decades, low-dimensional magnetic materials have been studied due to their exotic magnetic properties and superconductivity. KTb(WO4)(2) is one of these materials, which is considered a prototype of the 2D Ising model. However, its magnetization behavior at low temperatures shows nonlinearity that cannot be described by the pure two-dimensional Ising model. In this study, we propose using the anisotropic quantum Heisenberg model to describe the magnetic properties of KTb(WO4)(2) and simulate the magnetic properties using quantum Monte Carlo. The results show close agreement with experimental data, especially at low temperatures and intermediate values of the magnetic anisotropy parameter.

Summary: The electronic structure and ferroelectric-ferromagnetic coupling properties of Y-doped and vacancy-containing GaN-ZnO heterojunctions are systematically investigated. The magnetism in vacancy-containing systems is generated by the spin polarization of unpaired electrons induced by cationic vacancies, while in Y-doped systems, bound magnetic polarons are formed by the orbital hybridization of s-state and d-state electrons of Y-doped elements.

Summary: The elementary excitations spectrum of anisotropic frustrated antiferromagnets in the fan phase is discussed. It is found that the low-energy part of the spectrum consists of a gapless phason branch with linear dispersion and a gapped optical branch corresponding to the fan structure amplitude oscillations. In the high-energy part of the spectrum, the excitations are similar to the magnons of the fully polarized phase.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
