Summary: In this work, the authors investigate the strain effect on the physical properties of Sr2IrO4 thin films. The film on LaAlO3 substrate with compressive strain has a lower antiferromagnetic transition temperature compared to the film on SrTiO3 substrate with tensile strain. First principles calculations reveal that epitaxial strain plays a role in tuning the canting angle of J(eff) = 1/2 moments, which affects the magnetoresistance of the films. The film on LaAlO3 has higher magnetocrystalline anisotropy energy, causing difficulties in reaching the metastable state and explaining the distinct anisotropic magnetoresistance between the two samples.

Summary: In this study, the low-energy electronic structure of Sr2IrO4 was investigated using experimental observation and theoretical calculations. It was found that a simple pseudospin-12 model fails to fully capture the complexity of the system, and a realistic multiband Hubbard model is needed to describe the interplay between spin-orbital entanglement and electron-electron interactions. The results have implications for understanding multiorbital materials with closely spaced energy scales.

Summary: The low-energy jeff = 1/2 band of Sr2IrO4 shows similarities with the x2 - y2 band of La2CuO4, but no superconductivity has been observed in Sr2IrO4 even after doping. The failures of the jeff = 1/2 picture may be the reason behind this. However, our reanalysis using the local-density approximation plus dynamical mean-field theory approach suggests that the jeff = 1/2 state remains stable upon doping, supporting the existence of the jeff = 1/2 picture. Additionally, we find that Sr2IrO4 is a multiorbital system due to the hybridization with the jeff = 3/2 orbitals, which affects the Mott gap and the behavior of holes in the system.

Summary: Bulk Cr1_xMnxO2 samples were prepared using high pressure synthesis technology, and their crystal structure, magnetic properties, and electronic structure were investigated. The samples exhibited a rutile structure with space group P42/mnm, and the lattice parameter a remained unchanged while the lattice parameter c decreased with increasing Mn dopant content (x) and Metal-Metal bonding along the c-axis. The saturation magnetization of the samples decreased with increasing x. XPS analysis revealed electron transfer between Mn and Cr in Cr1-xMnxO2, with Mn existing as Mn2+ and Mn3+ ions and some Cr being oxidized to Cr6+. The calculated magnetic moment of Cr1-xMnxO2 was in accordance with the experimental data.

Summary: A series of Sn1-2x(AgBi)xSe samples were successfully synthesized using vacuum melting and spark plasma sintering methods. The cubic structure was obtained when x exceeded 0.2, thanks to the increased configurational entropy caused by AgBiSe2 solid solution. The optimized carrier concentration significantly enhanced electrical conductivity, reaching a maximum value of 350 Scm-1 in Sn0.5(AgBi)0.25Se. Combined with the low lattice thermal conductivity caused by small sound velocity and strong anharmonicity, the figure of merit of 0.08 was achieved in Sn0.6(AgBi)0.2Se at 500 K. Furthermore, the mechanical performance was also improved, with a high Vicker hardness of 1.5 GPa obtained in Sn0.4(AgBi)0.3Se. This work highlights the importance of configurational entropy in phase regulation and provides insights into the design of new thermoelectrics.

Summary: SLHN with K2NiF4-type structure exhibits high hydride ion conductivity. The structure of SLHN consists of hydride ions occupying equatorial and apical sites, while nitride ions preferentially occupy apical sites, with a substantial amount of anion vacancies observed. By partially substituting nitride ions with oxide and hydride ions, the electrical conductivity of SLHN can be further enhanced.

Summary: In this study, rocksalt-type Ti1-xMgxN crystals were successfully synthesized by the conventional bulk synthesis method, and it was found that the crystal structure and physical properties of Ti1-xMgxN can be tuned by the Mg content. A metal-to-semiconductor transition and suppression of the superconducting phase transition were observed when the Mg and Ti content ratio approached 1. Theoretical calculations showed that lattice distortions induced by the different ionic sizes of Mg and Ti increased with the Mg content, and the disordered cubic rocksalt structures became unstable. Furthermore, electronic structure calculations provided insights into the low resistance behavior and transport property evolution of Ti1-xMgxN.

Summary: In this study, a disordered cubic phase of rocksalt-type Ti1-xMgxN was successfully synthesized using the conventional bulk synthesis method. The crystal structure and physical properties of the Ti1-xMgxN solid solution can be tuned by the Mg content, showing a metal-to-semiconductor transition and suppression of the superconducting phase transition. The results demonstrate the feasibility of the simple bulk route for the synthesis of Mg-containing ternary nitrides and the modulation of nitride properties through heterovalent ion substitution.

Summary: A better control of the metal-electrolyte interface is essential for the development of rechargeable magnesium batteries. Coating the magnesium surface with an amalgam layer formed in contact with a mercury droplet shows an improvement in the plating/stripping process. However, detailed investigation reveals that the amalgam layer undergoes substantial chemical and morphological changes during cycling, indicating that it doesn't act as a protective coating but rather as an independent electrode material.

Summary: Layered oxides with the composition NaxMO2 have attracted attention for their composition diversity and promising electrochemical performances in sodium-ion batteries. This study attempts to synthesize sodium-rich P-type NaxMn2/3Ni1/3O2 and NaxMn1/2Ni1/2O2 and investigates their electrochemical behavior. The optimization of the synthesis protocol led to stabilize only P3-type single-phases. The investigation shows that the actual Na content is limited but still higher than conventionally reported for most of P3-type layered oxides.

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.
