Summary: Lead-based halide perovskite nanomaterials with excellent optical properties have been widely studied for applications in solar cells, light-emitting diodes, lasing, and X-ray imaging. However, the toxicity of lead has led researchers to explore alternative materials. In this study, all-inorganic manganese-based perovskite derivatives were successfully synthesized, and the introduction of a small amount of lead greatly improved photoluminescence intensity and quantum yield. These nanomaterials also showed high-efficiency X-ray absorption and radioluminescence, making them promising candidates for X-ray imaging.

Summary: Halide perovskites have great potential for memristor applications due to their superior electrical property, but their toxicity and unstable properties limit their use. In this study, lead-free all-inorganic perovskite Cs3Cu2Br5 films were used to fabricate memristors with Al/Cs3Cu2Br5/ITO structure. These memristors exhibit reproducible bipolar resistive switching behavior with low operating voltages, moderate resistance state ratio, and long retention time. The resistive switching effect is attributed to the formation/rupture of conductive filaments. Furthermore, the memristors maintain robustness in harsh environments with high humidity. This work provides opportunities for developing next-generation nonvolatile memories based on lead-free all-inorganic halide perovskites.

Summary: Light-induced phase segregation is a major obstacle for commercializing mixed halide perovskites in optoelectronics. We investigate this phenomenon in a model material system consisting of only surfaces and the bulk of a single-crystalline-like microplate. By utilizing environmental in-situ time-dependent photoluminescence spectroscopy, we observe the evolution of phase segregation under illumination and analyze the relationship between surface defects, carrier concentration, and the composition of iodide-rich phase. Our study provides microscopic insights into the complex evolution of phase segregation and highlights the importance of surface defects in modulating ion migration.

Summary: The superior tolerance of all-inorganic perovskites compared to their hybrid counterparts makes them promising candidates for solar cells. In recent years, significant improvements have been achieved in certified power conversion efficiencies of all-inorganic perovskite solar cells (PSCs), highlighting their potential for practical applications. Group IVA elements, including Pb, Sn, and Ge, have been extensively studied for perovskites, and their incorporation into all-inorganic perovskite structures provides opportunities for stabilizing the photoactive phase and tailoring the bandgap structure. This review analyzes the design principles, discusses the progress in PSCs with mixed group IVA cations, and provides perspectives on future research efforts for high-performance Pb-less and Pb-free all-inorganic PSCs.

Summary: Stabilizing Pt in N-doped carbon materials improves the performance of electrocatalytic methanol oxidation reaction (MOR), but the role of different N configurations remains unclear. This study uses Density Functional Theory calculations to understand the synergistic promotion of MOR by different N configurations. Electrodes with different ratios of pyridinic N and pyrrolic N were designed and synthesized, and Pt/N-CNT-600 showed superior electrocatalytic activity in acidic and alkaline media. The strong metal-support interaction induced by N-doping is the key reason for the high performance. Moreover, the ability of pyrrolic-N and pyridinic-N in promoting the adsorption and oxidation of CH3OH and the oxidation of CO* is highlighted for the first time. This work provides new insights for designing efficient electrocatalysts for MOR.
