However, the unique micro- and macrostructural effects of triboelectric fibers on contact-electrificaion (CE) have not been systematically studied, which result in the lower charge output compared to conventional film structure. Here, in order to provide theoretical guidance for designing high-performance triboelectric fibers with optimized structural designs, a systematic experimental measurement and theoretical analysis method is developed to explore the influence laws and potential mechanisms of the surface microstructural defects and overall macrostructural compositions of triboelectric fibers on their CE behaviors. It can be found that the surface microstructure defects contribute to increasing the total charge transfer, due to the increase in effective interface contact area. In addition, triboelectric fibers with core–shell coaxial structure prepared by uniform coating method have higher electrical output performance, which can ensure maximum contact between the conductive layer and the dielectric layer. This work provides a new research paradigm for studying the CE behavior and quantifying surface charges of complex structures, and suggests a multiscale structural design strategy for high-performance triboelectric fibers.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"83 ","pages":"Pages 295-306"},"PeriodicalIF":21.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601332","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}

However, their practical efficacy is often limited by inadequate expression of pyroptosis-executed gasdermin and insufficient transfer of tumor-derived DNA. In this work, our findings indicated that the epigenetic drug of decitabine (DEC) can increase the gasdermin E (GSDME) level in breast cancer cells, while the DNA-damaging chemotherapeutic drug of 7-ethyl-10-hydroxycamptothecin (SN38) can activate caspase-3 and cyclic GMP-AMP synthase-stimulator of interferon gene (cGAS-STING) pathway. Based on these discoveries, a glutathione (GSH)-responsive nanoplatform equipped with PD-L1 blockade peptide (PD-L1 pep) is further fabricated for targeting delivery of these chemotherapeutic combination to breast cancer cells. Interestingly, the apoptosis-pyroptosis switch (denoted as PL@SD) not only enables the cascade activation of caspase-3 and GSDME to induce an apoptosis-pyroptosis transition, but also accelerates the release of tumor-derived DNA through the pore-formation to elicit the cGAS-STING activity. Concurrently, PL@SD elevates dendritic cell maturation, cytotoxic T lymphocyte infiltration, natural killer cell recruitment and long-term immunological memory effect to boost adaptive and innate immunity, thus synergistically suppressing primary breast cancer, distant lung metastases and tumor rechallenge. Overall, this study presents an elaborate strategy for apoptosis-pyroptosis transition and cGAS-STING activation, which might provide a new insight to expand the applications of the existing therapeutic drugs for tumor immunotherapy.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"83 ","pages":"Pages 263-283"},"PeriodicalIF":21.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601330","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 strength-ductility trade-off is hardly broken by using one of the four traditional strengthening methods solely, namely, strain hardening, grain refinement, precipitation and solid solution strengthening. The design and development of advanced steels need to introduce as many strengthening mechanisms as possible for achieving desirable strength. To achieve good ductility with high uniform elongation before fracture, necking need to be suppressed by continuous work hardening of the material. Here, we demonstrate that by adding Al (∼6%) and Ti (∼3%) into the Fe-26Ni-1.2C (at.%) steel, nanosized γ′-(Ni, Fe)₃(Al, Ti) (∼20 vol%) can precipitate out in the initial austenitic matrix after one-step aging. The formation of γ′ nanoprecipitates triggers γ → α phase transformation of the matrix during cooling, introducing strain hardening due to volume expansion, and simultaneously refines grains from 15 to 1–2 μm due to the hindering effect of nanoprecipitates on grain boundary migration. Moreover, the γ′ nanoprecipitates not only can hinder dislocation motion in the matrix, but also can plastically deform under high stress to enhance the ductility of the steel. Therefore, the nanoprecipitate-strengthening ultrafine-grained steel suppresses necking instability, which enhances the strength, uniform elongation and work hardening capability simultaneously.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"83 ","pages":"Pages 213-222"},"PeriodicalIF":21.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601334","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}

However, the review specifically focusing on the progress of gas–liquid-solid photocatalysis over MOF-based materials is relatively scarce so far. Unlike the reaction of CO₂ gas with H₂O vapour in gas–solid mode, the gas–liquid-solid reaction system consists of diverse additives such as photosensitizers and sacrificial agents, which strongly depend on the structural design of photocatalysts. This review classifies the structure of MOF-based materials that correlated with their requirements of specific additives for driving CO₂ reduction. Specifically, we review the recent advances from the requirements of photosensitizers and sacrificial additives to the green overall photosynthesis (just using H₂O as the electron donor). The corresponding strategies for the structural design of MOFs from the aspects of crystal structure, building blocks, photosensitizer units are discussed to clarify the structure–activity relationship.

While self-healing of dynamic polymers is well documented for macroscopic samples under applied pressure, mild temperature, and prolonged times, self-healing at the nanoscale after extreme deformation at high rates is largely unexplored. We demonstrate the extensive puncture healing of furan/maleimide Diels-Alder polymer (DAP) covalent adaptive network (CAN) submicron thin films induced by supersonic micro-projectile impacts. For a given sample thickness to projectile size ratio, DAP submicron thin films display a significantly smaller perforation than glassy thermoplastics while showing adequate kinetic energy absorption. Post-mortem microscopic examination reveals efficient puncture healing that is enabled by spatiotemporal gradients in stress- and temperature-induced thermomechanical responses of DAP networks. These responses include a unique solid-to-liquid transition, in addition to viscoelasticity and viscoplasticity. Dissociation of DA bonds occurs due to adiabatic heating and high stresses. The partially dissociated network undergoes biaxial stretching until perforation with subsequent entropically-driven elastic recovery helping puncture closure. Infrared nanospectroscopy confirms that the chemical structure of DAP networks surrounding the puncture has recovered to that before the impact. The energy absorption is evaluated using in-situ imaging at nanosecond, micron-scale resolution.
