Summary: Perovskite lattice was modified with site vacancies and mixed anion composition to create Sr0.83Li0.17Ta0.83O1.88N0.74 (Li02N), which was further transformed into Sr0.83Li0.17Ta0.83O3 (Li02O) with optimized treatment. Both Li02N and Li02O showed Arrhenius behavior of ionic conductivity with different activation energies, suggesting that the nitride component enhances ionic conduction while anion lattice vacancies have the opposite effect.

Summary: In this study, the proton conduction mechanism in sodium tantalite with an orthorhombic perovskite structure was investigated using first-principles calculations. It was found that the tilting structure of the crystal led to interoctahedral hopping, which accelerated proton migration. Additionally, the calculated proton conductivity agreed well with the experimental results after considering the effect of dopants.

Summary: Metal thiocyanate perovskite-analogues are a promising class of materials that may exhibit interesting magnetic properties. In this study, we investigated the magnetic properties of a metal thiocyanate framework Cr[Bi(SCN)(6)]·xH(2)O and found that it undergoes long-range magnetic order at low temperature. The unique structure and frustrated antiferromagnetic interactions of this material suggest that further exploration in the design of metal thiocyanate perovskite-analogue structures may lead to the discovery of novel frustrated magnetism.

Summary: We report new hexagonal perovskite-related oxides Ba3W1+xV1-xO8.5+x/2, which have a higher bulk conductivity than the mother material Ba3WVO8.5. Increasing the excess W content in Ba3W1+xV1-xO8.5+x/2 leads to an increase in oxygen content, resulting in improved oxide ion conduction. These findings open new avenues in the science and technology of oxide ion conductors.

Summary: The study reports strong bright-exciton fine-structure splitting in solution-processed CsPbI3 perovskite quantum dots, which is robust to quantum dot size and shape heterogeneity and increases with decreasing temperature.

Summary: The martensite domain variant selection and stress-induced martensite morphology were investigated in [001]-oriented superelastic Co49Ni21Ga30 shape memory alloy single crystals under tensile load. The results showed that the precipitation of nanoprecipitates promoted the increase of habit plane interfaces and the reduction of martensite plate thickness. During tensile loading, all samples exhibited stress-induced formation of martensite, but the presence of nanoprecipitates did not necessarily promote multi-variant interaction.

Summary: The study demonstrates the significant impact of hydrogenation on the electrical and optical properties of a quasi-2D perovskite niobate, suggesting that altering the orbital occupancy of Nb d orbitals could trigger on-site Coulomb interaction. The observed electrical plasticity induced by hydrogen doping is utilized for simulating neural synaptic activity, shedding light on the role of hydrogen in 4d transition metal oxides and proposing a new avenue for designing novel electronic phases.

Summary: In recent decades, photocatalysis has emerged as a practical and environmentally friendly method for degrading pollutants and generating fuels using solar light. Traditional photocatalysts face limitations such as wider band gaps and quick recombination rates, prompting the search for alternative materials. Heteroanionic materials are seen as a promising solution due to their superior light absorption capacity, narrow band gaps, and improved resistance to corrosion. This article summarizes the recent developments in heteroanionic materials, their classification, synthesis techniques, and their role in photocatalysis.

Summary: Lithium-ion batteries have played a significant role in various applications, but the rising cost and limited availability of lithium have led to doubts about their ability to meet future energy demands. Sodium-ion batteries are considered a viable alternative due to the abundance of sodium resources and comparable electrochemical performance. However, the commercialization of Na-ion batteries has been hindered by material degradation and instability. Carbon nanotube-based metal sulfide composites are being explored as anode materials with low cost and higher capacities.
