To address this issue, a synergistic modulation strategy is developed via introducing a highly crystalline p‐type organic semiconductor C8‐BTBT as a solid additive into a binary system consisting of a polymer donor PM6 and a nonfullerene acceptor L8‐BO, to simultaneously improve charge dynamics and phase morphologies. Resulting binary OSCs yield a remarkable efficiency of 20.1% with an impressive fill factor (FF) of 81.9%. The achieved FF is the highest reported so far for the PM6:L8‐BO community. The competitive advantages of the modified photoactive layer are attributed to matched electronic structures that facilitate exciton dissociation at donor: acceptor heterointerface, reduced charge trap densities, more balanced charge mobilities, and suppressed charge recombinations, evidently demonstrated by a series of transient characterization technologies and quantitative theoretical analyses. Moreover, the optimized micromorphology features uniform fibrillar structures with improved dispersity, significantly promoting electrical properties. This work sheds light on a promising strategy for addressing the BHJ charge transport challenge and further enhancing the performance of OSCs.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"62 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145311066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emphasis is put on the transition from diffuse microcracking to localized macrocracking by incorporating poromechanical interaction. A micro-poromechanical model is first established for the description of diffuse damage and frictional sliding of microcracks by combining linear homogenization and irreversible thermodynamics. In particular, the concept of effective stress in the context of damage mechanics is revisited. The role of fluid pressure in cracking process is clarified. The onset of localized macrocracking is then described as stemming from the coalescence of microcracks when the diffuse damage density parameter reaches a critical value. After that transition point, the dissipation process in the SQBM is primarily attributed to the evolution of localized cracks. Within this frame, an anisotropic poromechanical model is developed for modeling the growth and frictional sliding of oriented localized macrocrack whose orientation is analytically determined and depends on loading path. The displacement discontinuity across the macrocrack can be evaluated. For assessing the performance of proposed approach, a set of examples are examined, including drained and undrained triaxial compression tests. In particular, analytical solutions are obtained and compared with existing experimental data, in terms of stress–strain relations, porosity and fluid pressure evolution, and the transition from diffuse damage to localized cracking.","PeriodicalId":340,"journal":{"name":"International Journal of Plasticity","volume":"1 1","pages":""},"PeriodicalIF":9.8,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145311271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although MLO-mimetic coacervates generated from synthetic biomaterials can deliver biomacromolecules into cells, they lack the conformational adaptability of IDPs and a defined internalization mechanism, limiting their stability under physiological conditions and hindering biomedical translation. Here, IDP-inspired nanovectors (IDP-NVs) are developed with conformational adaptability capable of forming nanocoacervates (NCs) with biomacromolecules for cytosolic delivery. Mixing with IDP-NVs and cargos results in stable NCs under physiological conditions, and the NCs can directly penetrate cellular membranes through the molecular motion of IDP-NVs. After the internalization, cytoplasmic glutathione triggers NC disassembly, releasing biomacromolecules in the cytosol. The NCs effectively deliver biomacromolecules of diverse sizes, charges, shapes (globular proteins and antibodies), and functions (mRNAs and CRISPR units), demonstrating their versatility and potential for biomedical applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"16 1","pages":"e07877"},"PeriodicalIF":29.4,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145311710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To mitigate ion-mediated degradation on operationally relevant time scales, this work investigates how introducing brief periodic intervals of light and darkness (LD cycling) can stabilize the average efficiency of perovskite films and devices. Systematic photoluminescence (PL) studies reveal that dark intervals on the order of seconds significantly suppress nonradiative recombination and slow degradation. The extent of PL enhancement depends on the duration of the dark time, the material composition, and critically, the sample's age. Remarkably, LD cycling increases PL by more than 7-fold even in aged samples that would otherwise undergo photodarkening under continuous illumination. Moreover, the PL kinetics under LD cycling mirror the corresponding open-circuit voltage dynamics in full solar cells, showing that local emission changes provide a direct measure of device-level behavior. Device measurements similarly show that LD cycling enhances the power conversion efficiency compared to continuous illumination and mitigates deterioration over extended operation. This strategy highlights a potential pathway to dynamically preserve or even improve perovskite performance in future optoelectronic applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"98 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Driven by considerations of environmental safety and economic feasibility, bio-based flame retardants are favored for their eco-friendly and sustainable characteristics. This study successfully scaled up the preparation of a P/N-rich cottonseed meal-based flame retardant (PmC) − a functional material in which phosphate groups are chemically introduced into the natural components of cottonseed meal. The innovative mechanical grinding method refines solid biomass for application on the surface of cotton fibers. PmC integrates with cotton fibers through a flame-retardant finishing process, forming hydrogen bonds and covalent bonds between PmC and cotton fibers, thereby achieving durable wash resistance for flame-retardant cotton fibers. The limiting oxygen index (LOI) of 110 g/L PmC treated cotton fibers reaches 38.4 %, with a damage length of only 50 mm. Cone calorimetry tests revealed that the total heat release (THR) and peak heat release rate (pHRR) of PmC-treated cotton fibers were reduced by 38.7 % and 82.9 %, respectively. Comprehensive analysis using TG-IR, residual carbon XPS, SEM-EDS further indicated that PmC primarily exerts its flame-retardant effect by acting on the condensed phase of cotton fabrics.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"101 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental results show that the Co-50Ni-10Al-6Ta-8Cr alloy exhibits good oxidation resistance, with weight gain following a parabolic law. After 25 hours of oxidation, the oxide film consists of three layers—a (Co, Ni)O layer, an α-Al₂O₃ layer and a τ + γ phase layer. After 200 hours of oxidation, the oxide film consists of a (Co, Ni)O layer, a Cr2O3 + CrTaO4 layer, an α-Al2O3 + γ layer and an AlN + τ phase layer. It is found that during the initial oxidation stage, the α-Al2O3 layer serves as the primary oxidation barrier, whereas in the later stage, the Cr2O3 + CrTaO4 layer exhibits superior oxidation resistance. Moreover, the Cr2O3 + CrTaO4 layer effectively reduces the oxygen partial pressure inside the oxide scale but was unable to suppress the inward diffusion of nitrogen, leading to the formation of AlN.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"36 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145311542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report the first demonstration of simultaneous enhancement of the Seebeck coefficient and electrical conductivity in p-type MoS₂/CuS nanocomposites through precise compositional tuning that activates a strong energy filtering effect. Leveraging the phonon liquid electron crystal (PLEC) nature of CuS, our approach delivers synergistic optimization of charge and phonon transport. The optimized 20 wt% CuS composite achieves a high electrical conductivity of 893 Scm-1 and a power factor of 41 μWm-1K-2 at 653 K, attributed to increased Cu2+ ion concentration and a high density of states near the Fermi level (~0.2 eV) enabled by band structure modulation. At the same temperature, the material also exhibits an ultra-low thermal conductivity of 0.2 Wm-1K-1 due to intensified acoustic and interfacial phonon scattering. This synergistic control of electronic and thermal transport represents a novel strategy for mid-temperature thermoelectric materials design, positioning MoS₂/CuS nanocomposites as promising candidates for next-generation power generation systems.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"10 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145311605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
