Summary: In this work, a novel inorganic halide Cs10MnSb6Cl30 with a distinctive 10H perovskite polytype structure is reported. The Cs10MnSb6Cl30 has 30% B-site vacancies ordered at both corner-and face-sharing sites, resulting in a reduction of octahedral connectivity to 1D and enhanced photoluminescence. This study demonstrates the existence of the 10H perovskite structure in halides and the potential of vacancy rearrangements to tune the optical properties of perovskite polytypes.

Summary: Identifying the working principles of heterogeneous catalysts is challenging due to the chaotic nature of catalysis. However, creating atomic order in catalysts simplifies this task and offers new opportunities for designing active sites. Recent advances in heterogeneous electrocatalysis have led to exciting progress in constructing atomically ordered materials. This review summarizes the latest progress in electrocatalysts with periodic atomic arrangements and discusses their synthesis principles and intriguing properties. Moreover, it outlines the promising prospects of atomically ordered catalysts in catalysis research.

Summary: The study shows that an array of nanomagnets coupled by real retarded exchange interactions can develop a new state of matter, termed as time frustrated matter (TFM). In a spin system with time-dependent retarded exchange interactions, a single spin flip does not instantly influence other spins but after some delay, leading to a change in the sign of the exchange interaction and the emergence of a non-Markovian temporal evolution.

Summary: In this study, we investigated the interplay between structural defects in NiFe2O4, showing that the complex formed by a Ni-Oh/Fe-Td-cation swap and a neutral oxygen vacancy is more stable than these two isolated defects, and significantly reduces the width of the minority-spin band gap.

Summary: This study investigates the composition-dependent ordering mechanisms of Pt-Fe alloy nanoparticles by in situ electron microscopy observations. The findings illustrate that the nanoscale size effect can influence the surface-core interaction and thus control the ordering processes.

Summary: This study investigated the temperature dependencies of viscoelastic energy dissipation and fatigue crack propagation in filled silicone rubbers and natural rubbers. The findings showed that both types of rubbers exhibit a power law relationship with an exponent of 1.5 between fatigue crack growth per cycle and a normalized driving force. Moreover, silicone rubber deviated from the power law relation at elevated temperature, with crack morphology influencing fatigue resistance.

Summary: This study examines the immune response of the terrestrial crustacean Porcellio scaber to different types of microplastics and natural particles. The results reveal dynamic changes in immune parameters after exposure to microplastics, with a gradual return to control values. Furthermore, the study demonstrates that immune parameters can serve as sensitive biomarkers of exposure to microplastics. The importance of using natural particles in microplastics studies and their effects is also discussed.

Summary: The study found that thermally induced cation ordering affects the emission color of spinel compounds, monitored through X-ray absorption and diffraction analysis. Thermal treatment can stabilize the compound's structure and change the emission color, with potential implications for thermal sensing applications.

Summary: This study reported a new type of layered oxide chalcogenides. Structural analysis revealed a partial ordering of alkaline earth cations and antiferromagnetic coupling of Fe3+ moments through Fe-O-Fe linkages in these compounds. These findings are significant for understanding the magnetic and structural properties of layered oxide chalcogenides.

Summary: In this study, metal halide perovskite quantum dots with mixed cations of Formamidinium (FA) and Cs were fabricated using a solution-processed method at room temperature. By controlling the Cs doping ratios, the optical properties of these mixed-cation perovskite quantum dots were systematically investigated. The temperature-dependent photoluminescence spectra showed blue shifts as temperature increased, with widening full-width at half maximum, attributed to lattice thermal expansion and carrier-photon coupling effects. Excess Cs doping affected the optical properties at low temperatures due to the introduction of detrimental defects in the perovskite crystals. Controlling doping concentrations is crucial for the preparation of high-quality perovskite quantum dots and efficient optoelectronic devices.

Summary: In this study, the magnetic ordering of ultrathin chromium tellurides was found to be structure dependent and tunable by external strain. First-principles calculations and Monte Carlo simulations showed long-range stable magnetism with high and low Curie temperatures, as well as short-range magnetism in 2D Cr5Te8, CrTe2, and Cr2Te3 layers.

Summary: An experiment was conducted to evaluate the effect of real-time temperature on the nonlinear deformation behavior of rock. It was found that the soft and hard parts of the rock respond differently to temperature changes, with the elastic modulus of the hard part increasing and the elastic modulus of the soft part decreasing. The study also identified a threshold temperature of 125°C.

Summary: In this study, anisotropy of magnetic susceptibility (AMS) was combined with fault kinematic analysis and sedimentologic data to analyze deposits of the Upper Red Formation in the intermontane Tarom Basin of NW Iran. The study found that the Miocene extension observed in the basin is not regionally pervasive and not controlled by large-scale processes, suggesting that the normal faults were gravity instabilities induced by sedimentary processes rather than extensional tectonics.
