To address this limitation, a novel ZIF‐8, namely heterogeneous ZIF‐8 (hZIF‐8), is developed, consisting of nanocrystalline ZIF‐8 phases with a minor amorphous polymer component introduced via in situ coordination. hZIF‐8 is synthesized through a Lewis‐acid‐catalyzed cationic ring‐opening polymerization of tetrahydrofuran (THF), generating polytetramethylene ether glycol (PTMEG) chains that competitively coordinate with zinc ions during ZIF‐8 crystallization. This coordination‐mediated heterogeneous structure exhibits unique characteristics distinct from conventional ZIF‐8 and other polymer hybrid MOFs such as PolyMOFs. The polymer phase effectively restricts the linker flexibility of the nanocrystalline phase at the molecular level, leading to significantly enhanced molecular sieving properties. As a result, hZIF‐8‐containing mixed‐matrix membranes (MMMs) exhibit a significant enhancement in C3H6/C3H8 separation performance, with the separation factor increasing from 13.3 to 75.5 (by 468%) and the C3H6 permeability from 7.4 to 17.4 Barrer (by 135%) at 30 wt.% loading. Furthermore, the intrinsic selectivity of hZIF‐8 is predicted to reach ≈3700, representing an order‐of‐magnitude improvement over that of pristine ZIF‐8 (≈180).","PeriodicalId":228,"journal":{"name":"Small","volume":"116 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144710663","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, high‐performing Ta3N5 photoanodes typically require Ta foil substrates and film thicknesses of several hundred nanometers, leading to increased tantalum usage and fabrication costs. This study introduces bixbyite‐type Ta2N3 as a superior precursor for synthesizing thin (≈100 nm) Ta3N5 films on silicon substrates, substantially reducing tantalum consumption while maintaining excellent PEC performance. The metastable Ta2N3 phase undergoes disproportionation into Ta3N5 and conductive Ta‐subnitrides during ammonolysis, enabling efficient charge separation without relying on Ta foils. Optimization of ammonolysis conditions reveals a critical balance between Ta3N5 crystallinity, subnitride content, and surface Ta3+ defect concentrations. Furthermore, degenerately doped silicon substrates enhance hole extraction by suppressing charge accumulation and leakage at the Ta3N5/Si junction, as revealed by photoelectrochemical impedance spectroscopy. This synthesis strategy yields an anodic photocurrent density of 3.86 mA cm−2 at 1.23 VRHE for a 100 nm Ta3N5 film on n+‐Si(111), outperforming a 500 nm film derived from TaOx precursor and achieving a 0.15 V cathodic shift in onset potential.

Nanoscale sensors can be attached to the surface or dispersed in solution, enabling the rapid detection of analytes with high sensitivity and specificity by overcoming concentration‐driven diffusion limits. In biological fluids, however, nanoscale objects are surrounded by biomolecules, mostly proteins, that form an evolving encapsulating surface layer, commonly known as the protein corona. The protein corona can modify the biosensor surface, which can adversely impact biosensing specificity, sensitivity, and accuracy. Conversely, the protein corona can be exploited to design biosensors for disease diagnostics, the discovery of new biomarkers, and environmental contaminants. In this review, the factors influencing protein corona formation on nanoscale biosensors are examined. Characterization methods and the effects of protein corona formation on the performance of nanoscale biosensors are also discussed.

Semiconductor-assisted photocatalysis has the potential to be a green method to achieve complete mineralization of PFAS. Cadmium indium sulfide (CdIn2S4) is an exciting photocatalytic material because of its high visible light harvesting capacity and high reduction potential. However, CdIn2S4 has not been investigated for PFAS degradation. Herein, CdIn2S4 micro-pyramids are fabricated via solvothermal synthesis, and their photocatalytic activity toward the photodegradation of perfluorooctanesulfonic acid (PFOS) is investigated. The reaction conditions, such as the light source and the light power are optimized. The findings show the capability of CdIn2S4 to achieve almost complete degradation and defluorination of PFOS (removal% = 99 ± 7% and defluorination% = 97 ± 22%) under optimized conditions. From radical quenching experiments, it is found that the mechanism of degradation is via photoelectron reduction. CdIn2S4 shows an outstanding performance toward the degradation of the PFAS sample derived from a contaminated facility in South Australia.

A potential strategy for bone repair that avoids the need for autogenous bone grafts is bone tissue engineering (BTE). Recently, BTE strategies incorporating vascularization, neurorestoration, and immunomodulation of bone substitutes are regarded as a comprehensive and promising method for bone repair. Despite advancements, existing approaches struggle to achieve overall bone regeneration. Emerging DNA nanotechnology, specifically tetrahedral framework nucleic acids (tFNAs), presents a transformative approach due to their rapid self-assembly, structural stability, efficient cellular uptake, multiple biological activities, and excellent biocompatibility. tFNAs allow for flexible modifications with various bioactive molecules, including oligonucleotides, peptides, and small molecular drugs, thus strengthening their targeting and therapeutic abilities. tFNAs can enhance osteogenesis by promoting mesenchymal stem cell viability and differentiation, thereby stimulating bone formation. Furthermore, tFNAs integrated with scaffolds contribute to the development of advanced biomaterials with superior osteoinductive properties. tFNAs also influence angiogenesis, neurorestoration, and immunomodulation, all of which are crucial for bone repair. This review not only examines the potential applications of multifunctional tFNAs in BTE but also provides critical insights into the advantages, challenges, and prospects of tFNAs in BTE.","PeriodicalId":228,"journal":{"name":"Small","volume":"18 1","pages":"e2411930"},"PeriodicalIF":13.3,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701057","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, fabricating high-quality top inorganic ETLs that preserve the active perovskite layer remains a challenge. Herein, a composite electron transport bilayer comprising atomically coherent interfaced tin dioxide (SnO2) nanoparticles and tungsten-doped zinc oxide (WZO) is introduced, which further facilitates charge extraction and mitigates detrimental interfacial deprotonation reactions. The tungsten doping ratio can be precisely controlled by adjusting the co-evaporation parameters. The results reveal that tungsten enhances charge extraction by fine-tuning the energy levels, whereas the SnO2 layer simultaneously passivates the perovskite/ETL interface defects and inhibits deprotonation reactions. Utilizing this inorganic composite multiple architecture, a record efficiency of 23.19% is achieved for inverted PSCs with an all-inorganic ETL.

This review presents a transformative paradigm centered on hierarchical structural engineering-encompassing atomic-to-macroscale interfacial design and textile-architecture optimization-to address these barriers. The roles of gradient-pore distributions, Janus-structured fibers, and kirigami-inspired geometries are systematically dissected in homogenizing Li-ion flux, stabilizing SEI layers, and decoupling mechanical stress from electrochemical pathways, enabling TLMBs to sustain >500% strain without capacity loss. Furthermore, system-level integration strategies for self-powered health-monitoring textiles and thermally adaptive batteries are scrutinized, bridging fundamental insights with scalable manufacturing. By identifying underexplored frontiers such as dynamic SEI regulators and circular economy-aligned designs, this work provides a strategic roadmap to advance TLMBs toward high-energy, mechanically robust wearable systems.
