The fatigue-induced stress redistribution in three-dimensional (3D) braided composites, even when subjected to externally constant-amplitude fatigue loads, results in locally-variable-amplitude fatigue loading, significantly impacting their fatigue performance degradation. This paper is aimed to propose a novel fatigue damage analysis method to predict the fatigue behavior of 3D braided composites subjected to locally-variable-amplitude loading. To this end, the continuous damage method, residual strength, residual stiffness, and fatigue life models are combined to characterize the properties degradation of 3D braided composites with cycling. Once stress redistribution occurs, the fatigue properties degrade based on the new stress level, and the equivalent cycle number is recalculated accordingly. As the material undergoes different cycle blocks, damage accumulates, ultimately leading to failure when the overall stiffness of the material degrades to 80%. Traditional fatigue models are also employed to predict the fatigue behavior of representative volume elements for comparison. The results predicted by the present model shows good agreement with experiments. Furthermore, the influence of stress levels and architectures of 3D braided composites on fatigue performance is systematically discussed. © 2024, The Authors. All rights reserved.

The cost-effective commercialization of perovskite solar cells (PSCs) requires eliminating the dependency on a strictly controlled atmosphere during their fabrication process. However, this remains a significant challenge due to the high sensitivity of the perovskite crystallization process to humidity. Here, the synergistic effects of residual solvent and environmental humidity on the crystallization process of perovskite films are studied. The high water-solubility and volatility of the residual isopropanol (IPA) solvent in precursor film are major contributions to water sensitivity and poor control over the crystallization process. A solvent environment engineering is proposed to improve the reproducibility of PSCs fabricated in air. A low-water-solubility and low-boiling-point solvent, isobutanol (IBA), is introduced to inhibit water intrusion and prolong the crystallization process through slow evaporation. This approach facilitates the production of high-quality perovskite films (1.56–1.57 eV) and PSCs across a broad humidity range (20–80% RH), consistently achieving efficiencies exceeding 21%. Notably, devices prepared in the air at 60% RH achieve a high PCE of 25.1%. The unencapsulated devices retain 97% initial efficiency after 1000 h of operation at maximum power point under one sun illumination. This study presents an efficient strategy that promotes the large-scale production of perovskite photovoltaic modules. © 2025 Wiley-VCH GmbH.

Polycarcin V induces DNA-damage response and enables the profiling of DNA-binding proteins

To maintain genomic integrity and avoid diseases, the DNA-damage response(DDR) not only detects and repairs DNA lesions, but also contributes to the resistance to DNA-damaging *** the DDR plays a significant role in drug discovery using the principle of synthetic lethality. The incomplete current knowledge of the DDR encouraged us to develop new strategies to identify and study its components and pathways. Polycarcin V, belonging to the C-aryl glycoside natural products, is a light-activatable DNA-intercalating agent that causes DNA damage by forming a covalent [2+2]cycloadduct with thymine residue under 365–450 nm of light irradiation in a DNA-sequence-independent manner. Taking advantage of the light-activatable feature and temporal control of DDR, we designed and synthesized polycarcin V-based bifunctional chemical probes, including one that cross-links DNA to DNA-binding protein to explore the DDR induced by polycarcin V and uncover novel DNA–protein interactions. Utilizing this chemical probe and activity-based protein profiling-stable isotope labeling with amino acids in cell culture, we identified 311 DNA-binding protein candidates, including known DDR factors and additional proteins that may be of interest in discovering new biology. We validated our approach by showing that our probe could specifically cross-link proteins involved in nucleotide excision repair(NER) that repair bulky DNA adducts. Our studies showed that the [2+2] cycloadduct formed by polycarcin V could indeed be repaired by NER in vivo. As a DNA-damaging agent, polycarcin V or its drug-like derivative plus blue light showed promising properties for psoriasis treatment, suggesting that it may itself hold promise for clinic applications.

Graphene-based active carbons(G-ACs) with a high specific surface area and high conductivity are promising electrode materials for high-performance supercapacitors. Typically, however, syntheses of the G-ACs call for expensive raw materials and are cumbersome. Here, the G-ACs are obtained by direct chemical activation of petroleum asphalt. The highest specific surface area of the prepared G-ACs is 3505 m^(2)/g and the corresponding conductivity is 32 S/m. Electrodes fabricated using the as-prepared G-ACs, i.e., without any conductive additives, demonstrate high specific capacitance and high rate performance. The specific capacitances of optimized G-ACs, as measured in a 1 mol/L TEABF_(4)/AN electrolyte and the neat ionic liquid EMIMBF_(4), are 155 and 176 F/g at 1 A/g, providing the high energy density of 39.2 and 74.9 W h/kg, respectively. In addition,the G-ACs exhibited excellent rate capability with a negligible capacitance decay from 0.5 to 10 A/g in both 1 mol/L TEABF_(4)/AN and neat EMIMBF_(4) electrolytes. Furthermore, the optimized G-AC has a high energy density(68.5 W h/kg) at a relatively high power density(8501 W/kg), indicating that it holds potential for application in green energy storage.

Over the past several decades, the integration of IONs into EP emerged as an effective method for enhancing its mechanical properties. Nevertheless, challenges remain, especially with u-IONs, where the interfacial strength with EP is suboptimal, resulting in aggregation within the EP matrix and a subsequent deterioration in the mechanical performance of u-ION/EP nanocomposites. In this comprehensive review, we explored advanced chemical modification techniques tailored for IONs incorporated into EP, providing a detailed examination of the mechanical characteristics of surface cm-ION/EP nanocomposites. This review investigates various chemical modification methods and their distinct impacts on the mechanical attributes of the resulting EP nanocomposites. Special emphasis is given to addressing the persistent challenges of inadequate interfacial strength and aggregation. Furthermore, this article examines prospective surface modification approaches for inorganic oxide nanoparticles, offering a visionary outlook on methods to improve the mechanical performance of EP in future. © 2024 Chongqing University
