Catalysts are pivotal in overcoming these energy barriers, enhancing reaction rates and selectivity. The strategy of atomic size misfit, which introduces structural defects like vacancies, grain boundaries, and dislocations, has gained attention as a promising approach to optimize catalytic activity. This strategy modulates atomic interactions, alters electronic structures, and enhances the reactivity of active sites, facilitating the activation of small molecules. Moreover, this approach holds significant potential for reducing environmental impact by enabling more efficient and sustainable chemical processes. However, current research on atomic size misfit remains fragmented, lacking a unified framework. A comprehensive review of this strategy is essential to consolidate its mechanisms, applications, and integration with other catalytic tuning methods such as alloying and doping. This review aims to provide valuable insights into the design of next-generation catalysts, guiding future developments in energy conversion technologies and offering pathways for practical, scalable applications in small molecule activation.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"56 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144137187","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}

These cationic Tri-Py oligomers can be easily decorated with various functional groups, enabling modification of antibacterial activity and selectivity against Gram-positive and Gram-negative bacteria. Compared with conventional antibiotics, Tri-Py oligomers can effectively combat drug-resistant bacteria and their corresponding biofilms by dual disruption of bacterial membrane and DNA, leading to low drug resistance and cross-resistance. In addition, they demonstrated excellent in vivo antibacterial efficacy and biocompatibility in mouse models of skin wounds and peritonitis induced by drug-resistant bacteria.

However, developing oral antioxidant nanozymes with stable and efficient superoxide dismutase-catalase (SOD-CAT) cascade activity remains challenging. Herein, montmorillonite (MMT) is employed to modulate the upward shift of the MnO2-x d-band center, thereby enhancing its SOD-CAT activity and stability. Both experimental and theoretical analyses reveal that the strong interfacial interaction between MMT and MnO2-x improves stability, reduces the oxygen vacancy formation energy of MnO2-x, and elevates the Mn d-band center. This upward shift enhances the adsorption of key intermediates, such as *OH and *O2, in the SOD and CAT reaction pathways, which in turn lowers the energy barrier of the rate-determining step. MnO2-x@MMT effectively scavenges intracellular ROS through the SOD-CAT cascade reaction. Transcriptomic analysis further elucidates the molecular mechanisms through which MnO2-x@MMT alleviates cellular oxidative stress by activating autophagy and mitophagy pathways. Furthermore, MnO2-x@MMT accumulates at the site of enteritis via electrostatic adsorption, exerting antioxidant therapeutic effects and facilitating the restoration of intestinal microecology. Collectively, utilizing minerals to modulate the upward shift of the antioxidant cascade nanozyme d-band center offers novel insights for the design of materials targeting IBD.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"33 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144137190","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}

Additionally, commonly used probabilistic computing devices like LBNM and sMTJ suffer from problems related to volatility and initialization. This paper explores the application of non-volatile combined bit (c-bit) devices, exhibiting back-hopping-like phenomena, in logical operations, arithmetic computations, and data backup and recovery. Logical reverse inferences are successfully implemented for AND, OR, XOR, and XNOR operations. Importantly, the logical reverse inference of full and half adders is achieved, as well as the decomposition of addends, verifying the feasibility of c-bit devices in complex arithmetic operations. Furthermore, by utilizing multiple c-bit devices working in tandem, efficient data backup and reliable recovery are achieved, offering a novel solution for data security.

However, the synthesis of short‐chain sulfur composites that simultaneously feature high sulfur content and high conductivity remains a significant challenge. Herein, the facile fabrication of conductive short‐chain sulfur composite with ultra‐high sulfur content (42.5 wt%) for efficient Na/K‐ion storage is reported. The protocol relied only on the industrial pitch and elemental sulfur as precursor via a simple heat treatment at low temperature (e.g. 450 °C). Rich delocalized C═C and C═S bonds are introduced into the carbon skeleton, forming the spatial π‐electron conjugation and spatial sp2‐hybridization, and resulting in a six‐order‐of‐magnitude enhancement of the electronic conductivity compared to the pitch‐derive carbon. The short‐chain sulfur species demonstrate superb reactivity with both Na‐ion and K‐ion without dissoluble polysulfide formation. A surface‐dominated storage mechanism enables outstanding electrode kinetics with diminished electrode deformation. As anodes, this composite delivers extraordinary reversible capacities for both Na‐ion (848 mAh g−1) and K‐ion (699 mAh g−1) storage with superior rate and promising cyclability.

Here, a magnetoelectric suture is developed by incorporating core‐shell magnetoelectric nanoparticles within a piezoelectric P(VDF‐TrFE) matrix. Upon external magnetic field exposure, magneto‐mechano‐electric cascade synergistically generated a programmable electrical output, thereby enabling spatiotemporally controlled electrical stimulation at the wound site. The ME suture is engineered with a polyzwitterionic hydrogel skin, imparting them with improved mechanical compliance, biocompatibility, and reduced foreign body response, and enabling friction‐minimized removal. In a rat incisional wound model, the ME suture with daily magnetic induction achieved significantly faster healing by reducing the recovery time from ten days to just five days. This work establishes a paradigm for intelligent suture systems, offering a theranostic platform that synergizes mechanoadaptive properties with electrically augmented tissue repair for next‐generation wound management.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"4 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144133482","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}

Nevertheless, LiMn2O4 is subjected to subpar electronic/ion conductivity and continuous capacity attenuation triggered by the Jahn-Teller distortion. In this regard, metal-organic frameworks (MOFs) are potential morphological controllers that impact particle size and crystal orientation and offer vacancy-accepting layers that facilitate oxygen defect formation, which boost electron/ion diffusion when utilized as self-sacrificial templates. The dissatisfying capacity retention caused by Mn2+ dissolution related to the Mn3+ disproportion is another tricky issue, which requires resolution through surface modification. To attain these goals, this work develops a strategy intermarrying the merits of oxygen defects and Zn-based zeolitic imidazolate framework-62 (Zn-ZIF-62) glass shields. Mn-MOFs with carboxyl-based ligands possessing various coordination numbers are adopted as precursors to optimize the morphological feature and modulate the oxygen vacancy level.
