The high specific capacity and voltage of Li-rich Mn-based oxides make them promising cathode materials for high-energy-density lithium-ion batteries (LIBs). However, the problems such as low initial coulombic efficiency, fast capacity and voltage fading, poor kinetics, large voltage hysteresis, and poor safety performance hamper their fast commercialization. Herein, we report one-pot K+ and PO43− co-doping Li-rich Mn-based oxides Li1.2Ni0.13Co0.13Mn0.54O2 cathode material to improve the electrochemical performance of the lithium-ion battery. On the one hand, K+ doping can stabilize the bulk structure and enlarge the Li slabs to facilitate the diffusion of Li+, resulting in enhanced cycling and rate performance. On the other hand, PO43− doping changes the electronic structure of the material and weakens the covalency of TM-O, decreasing the irreversible loss of lattice oxygen and stabilizing the structure. As a result, the K+ and PO43− co-doping can effectively alleviate the capacity and voltage decay and the modified sample shows better cycling stability (88.6%@0.5 C@250 cycles) and rate performance (155.5 mAh g −1@5 C) compared to the pristine material. Our strategy here provides a facile one-pot method to modify Li-rich Mn-based oxides cathode material for high-performance LIBs. © 2023

Peripheral nerve regeneration is impeded by an imbalanced microenvironment involving inflammation, oxidative stress, and inadequate vascularization. Traditional drug therapies are limited by poor blood-nerve barrier penetration and lack of multifunctional efficacy. Nitric oxide (NO), a critical gasotransmitter, promotes nerve repair by enhancing axonal growth, synaptic plasticity, and cell survival, while exerting anti-inflammatory, antioxidant, and pro-angiogenic effects. However, uncontrolled NO release risks cytotoxicity. To address this, we engineered a multifunctional hydrogel by grafting RGDC peptides onto chitosan to create an oriented microstructure, incorporating glutathione as a precursor for S-nitrosoglutathione (GSNO), a sustained NO donor. This design combines structural guidance with controlled NO delivery and antioxidant activity. The hydrogel demonstrated excellent biocompatibility and sustained NO release, avoiding cytotoxic levels. The RGDC peptide enhanced cell adhesion and migration, while GSNO effectively reduced intracellular reactive oxygen species (ROS) and promoted human umbilical vein endothelial cell (HUVEC) angiogenesis. The integrated system synergistically modulates the regenerative microenvironment by mitigating oxidative stress, supporting vascularization, and guiding cellular behavior. This strategy overcomes limitations of conventional treatments by combining structural alignment, controlled gasotransmitter release, and multifunctional bioactivity, offering a promising translational solution for peripheral nerve repair. © 2025, The Authors.

The fabrication of infrared photoluminescent transparent ceramics with excellent performance has been attracted wide attention. Thereinto, selecting suitable host material and luminescent ions is the premise of achieving excellent optical performance. In this work, based on Y2Zr2O7 as host material, a series of single phase rare-earth (RE= Ho3+, Er3+, Tm3+) doped transparent ceramics were prepared via solid-state reaction and vacuum sintering method, which obtained the highest transmittance (＞75%) in visible and near infrared regions. Through the study of photoluminescence characteristics, strong down-conversion infrared emissions of the rare-earth ions were observed. Combining with the excellent optical properties and relatively simple preparation method, Ho3+/Er3+/Tm3+ doped Y2Zr2O7 transparent ceramics, as novel infrared phosphor materials of A2B2O7 system, can find potential applications in the field of biomedicine, laser application and lighting, etc. © 2023, The Authors.

The two-dimensional (2D) organic-inorganic perovskite of unique optical properties and improved stability holds great potential in high-performance perovskite optoelectronic applications. However, a huge challenge to manufacture continuous thin films at large scale and low cost is still unresolved. Here, a facile method to fabricate high quality (PEA) 2 PbI 4 thin films at low temperature in the air condition by one-step anti-solvent associated method was firstly proposed. The mechanism of nucleation sites formation and grain growth rates governed by the polarity and saturated vapor pressure of anti-solvents and annealing temperature was disclosed. By comparing different anti-solvents at various annealing temperatures, high quality thin films with the lowest annealing temperature of 80 °C were achieved by using toluene. A simple planar photodetector was configured, with the Responsivity (R s ) and Detectivity (D*) of 752 μA/W and 2.76×10 8 Jones with active area of 150 μm × 8000 μm, respectively, and the stability keeping 92% after 90 cycles under continuous light illumination in the air. This method offers a simple and low cost approach for manufacturing high quality 2D perovskite films and high-performance photodetectors at low temperature for industrial applications. © 2022, The Authors.

In this study, n-type stannic sulfide (SnS2) nanosheets and p-type bismuth oxychloride (BiOCl) nanosheets prepared by hydrothermal method are utilized to construct the heterostructure SnS2-BiOCl composite through ultrasonication and grinding procedures. The piezoelectric SnS2-BiOCl heterojunction nanosheets are incorporated into the ferroelectric polyvinylidene fluoride (PVDF) membrane to fabricate the PVDF-based SnS2-BiOCl (PVDF-SnS2-BiOCl) flexoelectric strain sensor. The optimal amount of SnS2-BiOCl heterojunction in the PVDF-SnS2-BiOCl membrane is determined. A thorough analysis is conducted on the impact of bending curvature, frequency of bending, the size and thickness of the membrane, water flapping, underwater bending, resistance to fatigue from repeated bending, and resistance to corrosions from acid and alkali on the membrane's output current and voltage. The experimental and density functional theory (DFT) calculation results indicate that the PVDF-SnS2-BiOCl(2:1)-10% membrane, functioning as a smart strain sensor, has the ability to monitor human joint movements and water fluctuations in different situations. Additionally, it can be used as a coating for polyester and linen fabrics and can be connected in series or in parallel. The experimental findings align closely with the results obtained from DFT calculations. The outcomes demonstrate that the PVDF-SnS2-BiOCl membrane strain sensor, which is highly flexible, sensitive, and attachable, is well-suited for smart wearable electronic materials. © 2024, The Authors.
