However, their serious volume expansion leads to electrode pulverization and repeated rupture of the solid electrolyte interphase (SEI) film, severely compromising the cycle life. Confinement engineering has recently emerged as a powerful strategy for addressing the intrinsic limitations of alloying‐type anodes. Nevertheless, systematic classification and in‐depth mechanism clarification of diverse confinement strategies remain lacking. To fill this gap, this review systematically summarizes the fundamental principles, structural motifs, and design strategies of confinement engineering. Different from previous material‐oriented reviews, this work categorizes confinement engineering into self‐confinement and extrinsic confinement, and profoundly clarifies the structure‐regulation mechanism at the micro/nano scale, emphasizing the critical role of confinement engineering in mitigating volume expansion, stabilizing SEI films, and enhancing reaction kinetics. Key advances in alloying‐type anode development are highlighted, alongside a critical assessment of the persisting challenges. Finally, future directions are outlined to provide theoretical guidance and innovative strategies for accelerating the commercialization of alloying‐type anode materials for high‐energy‐density and long‐cycle‐life SIBs.","PeriodicalId":228,"journal":{"name":"Small","volume":"19 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172955","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}

However, their performance is still limited by poor molecular ordering and the difficulty in achieving effective gate‐controlled modulation. Here, a siloxane crosslinking strategy is proposed by incorporating 1,6‐bis(trichlorosilyl)hexane (C6Si) into poly(3‐hexylthiophene) (P3HT) to form a dense cross‐linked network, enabling improved molecular ordering, backbone planarity, and interfacial stability. As a result, a pronounced edge‐on molecular orientation of 93.00% was achieved, establishing efficient vertical charge transport pathways. The ion gel‐gated VOSTs exhibited excellent electrical performance at an ultralow operation voltage (−0.5 V), including high on/off current ratio ( I on / I off ) (9.48 × 10 4 ), low subthreshold swing ( SS ) (111 mV dec −1 ), and the minimum synaptic‐event energy consumption at low level (∼50 aJ), along with rich synaptic plasticity.

This review integrates experimental insights with multiscale computational approaches, including density functional theory (DFT), grand canonical Monte Carlo, molecular dynamics, and computational fluid dynamics (CFD). DFT calculations provide molecular‐level understanding of adsorption behavior, highlighting the role of electronic structure at open metal sites and functionalized pores. Classical simulations predict adsorption capacity, selectivity, and diffusion, while CFD extends these insights to macroscopic transport and process‐level performance, enabling direct comparison with experiments. In addition, emerging data‐driven approaches are discussed to uncover structure–property relationships and accelerate performance prediction across large materials spaces.

This study systematically investigates the influence of various chiral supramolecular NFNs on neural cell differentiation. A series of chiral supramolecular NFNs was synthesized using L/D‐amino acids and their derivatives as building blocks, including L/D‐lysine (L/D‐Lys), L/D‐histidine (L/D‐His), L/D‐arginine (L/D‐Arg), and L/D‐glutamic acid derivatives (Fmoc‐L/D‐Glu). The regulatory effects of these NFNs on the NG108‐15 were evaluated during the differentiation process. Our findings demonstrate that the chiral microenvironment established by D‐Lys‐gel significantly enhances NG108‐15 differentiation and correlates with robust activation of the Ca 2+ signaling pathway. To further elucidate the relationship between supramolecular chirality and metal ions, we synthesized chiral supramolecular NFNs from L/D‐Lys‐Ca 2+ ‐gel and L/D‐Lys‐Mg 2+ ‐gel. Notably, the supramolecular NFNs derived from D‐Lys‐Ca 2+ ‐gel exhibited superior capacity to promote neurite outgrowth and maturation compared to their L‐enantiomer and Mg 2+ ‐incorporated counterparts. Proteomics analysis revealed that the chiral supramolecular NFNs obtained from D‐Lys‐Ca 2+ ‐gel enhance neuronal differentiation by upregulating key effectors involved in both axon guidance and calcium signaling pathways, particularly the Camkk2‐Tiam1 cascade. This study provides valuable insights into the design of chiral biomaterials and proposes novel strategies for neural regeneration and tissue engineering.","PeriodicalId":228,"journal":{"name":"Small","volume":"15 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172680","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}

Drug‐induced immunogenic cell death (ICD) is a promising approach. However, its efficacy is curtailed by limited tumor‐cell targeting with collateral immune‐cell damage and by overactive efferocytosis that rapidly removes ICD‐associated danger signals, thereby restricting antitumor immunity. Herein, we develop a microenvironment‐responsive nanocarrier co‐delivering both PLK1 inhibitor (BI6727) and TIM‐3 inhibitor (ML‐T7). It integrates dual‐bioeffect of synthetic lethal selective ICD and whole‐immuno system remodelling initiated by effective macrophage efferocytosis inhibition. In detail, the molecular hallmark differences between tumor and immune cells was utilized to provide high‐quality antigens. Meanwhile, the nanotherapeutic enables serial phagocyte regulations, such as, suppressed macrophage phagocytosis, enhanced antigen recognition and phagocytosis by dendritic cells (DCs), and then alleviated T cell exhaustion. The underlying mechanism of nanotherapeutics‐mediated overall immune system reprogramming was explored by transcriptional profile analyses. These findings indicate that precise molecularly targeted ICD combined with coordinated immune activation enables efficient primary tumor suppression and promotes T‐cell phenotypes associated with antitumor immune memory, providing a novel paradigm for cancer immunotherapy.","PeriodicalId":228,"journal":{"name":"Small","volume":"19 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172687","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}

Here, we develop an aerosol‐jet printing (AJP) approach to fabricate S‐scheme SrTiO 3 /g‐C 3 N 4 heterojunction photoanodes with well‐controlled stacking sequences. The interfacial built‑in electric field drives recombination of SrTiO 3 photogenerated electrons with g‑C 3 N 4 holes, preserving the strongly oxidizing holes in SrTiO 3 for the oxygen evolution reaction (OER). The SrTiO 3 ‐on‐C 3 N 4 configuration delivers enhanced PEC water oxidation activity, with a photocurrent density of 2.3 mA cm − 2 , double that of single‐component and reversed‐structure photoanodes. It is found that this enhancement stems from stacking‐order‐dependent synergy between the heterojunction built‐in electric field and semiconductor‐electrolyte band bending.

A one‐dimensional nanoensemble composed of Ag nanowires decorated with Pt nanoparticles integrates electronic hybridization, facet‐dependent charge accumulation, and directional charge transport to boost HER.
