Summary: This study demonstrates for the first time the modulation of non-collinear antiferromagnetic phase transition in a heterogeneous system using thermal stress. The addition of a secondary phase leads to a shift in the transition temperature and the appearance of a new magnetic transition. Neutron powder diffraction analysis reveals structural changes and spin reorientation as the cause of the transition.

Summary: In this work, the Mn2SiX4 olivines (X=S, Se) were studied using magnetic susceptibility, X-ray and neutron diffraction. The crystal structures of Mn2SiS4 and Mn2SiSe4 were determined using synchrotron X-ray, neutron diffraction, and X-ray total scattering data. It was found that the Mn triangle forming the sawtooth lattice is isosceles in both compounds. The temperature evolution of magnetic susceptibility showed anomalies below 83 K and 70 K for Mn2SiS4 and Mn2SiSe4, respectively, indicating the presence of magnetic ordering. Neutron diffraction measurements revealed that the magnetic space groups of Mn2SiS4 and Mn2SiSe4 are Pnma and Pnm ' a ', respectively.

Summary: The co-doped graphite carbon nitride catalyst with B atoms and cyano groups exhibited excellent photocatalytic nitrogen fixation performance and stability, attributed to the nitrogen vacancies created by the dopants that enhanced the electron transfer rate and separation efficiency. The nitrogen photofixation rate of the catalyst was significantly higher than that of pure carbon nitride, and the NH4+ generation rate remained stable even after multiple cycles, showcasing its potential for sustainable nitrogen conversion applications.

Summary: This study investigates the variation in crystallinity, morphology and phase of zinc tin hydroxide nanostructures after annealing in different atmospheres. Annealing in oxidizing and non-oxidizing atmospheres does not significantly affect the properties. However, annealing in a reducing atmosphere leads to a transformation in morphology and structure, with the formation of new phases. The reducing atmosphere also affects the bandgap and other electronic properties of the nanostructures.

Summary: This work presents a novel tubular g-C3N4 with a hierarchical core-shell structure achieved through the incorporation of phosphorous elements and nitrogen vacancies. The core is composed of randomly stacked ultra-thin nanosheets, enabling efficient electron/hole separation and visible-light absorption. This photocatalyst demonstrates outstanding performance in the photodegradation of rhodamine B and tetracycline hydrochloride under low intensity visible light, as well as remarkable hydrogen evolution rate under visible light. The introduction of phytic acid into the melamine and urea solution during hydrothermal treatment leads to the formation of this hierarchical structure, offering a facile and scalable approach for mass production.

Summary: The effect of partial substitution of Mo with W in Co3Mo3N and Ni2Mo3N on ammonia synthesis activity and lattice nitrogen reactivity was investigated. It was found that the catalytic performance decreased with the introduction of tungsten. Furthermore, substitution with tungsten did not have a significant effect on lattice nitrogen reactivity, but resulted in a loss of lattice nitrogen in Co3Mo2.6W0.4N and Ni2Mo3N.

Summary: Pressure is a fundamental thermodynamic variable that has led to prosperous progress in multiple fields by creating exotic materials and modulating transport properties. In the context of inorganic thermoelectric materials, pressure is essential for preparing solid-state materials with specific properties. However, the additional influence of pressure on thermoelectric performance is often underestimated. This review summarizes recent progress in understanding the effects of pressure on crystal structure, electrical transport properties, microstructure, and thermal conductivity in thermoelectrics, and proposes perspectives and strategies for improving thermoelectric performance through pressure modulation.

Summary: In this study, polycrystalline magnesium silicide (Mg2Si) and magnesium germanide (Mg2Ge) were successfully synthesized for the first time using the microwave-induced-metal-plasma (MIMP) approach. The ultrafast reaction kinetics in these preparations were attributed to the formation of reactive Mg plasma facilitated by the high-frequency electromagnetic field. Characterization techniques such as PXRD, SEM combined with EDX, and XPS confirmed the high purity of the products. The MIMP method not only enables the sustainable synthesis of Mg2X materials but also allows for the production of intermetallics and Zintl phases of prescribed morphology.

Summary: Establishing links between the structure and physical properties of solid-state ionic conductors is important for understanding their fundamental nature and accelerating the discovery of new materials. In this study, the interplay between lattice dynamics, electronic structure, and electrochemical properties in the isostructural family of lithium tetrahaloaluminates LiAlX4 (X = Cl, Br, I) was explored. Experimental methods and theoretical calculations were used to demonstrate that softer lattices provide lower activation energies for lithium ion migration. However, the relationship between polarisability and lithium ion conductivity is not straightforward and requires further investigation.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
