Due to its hydrophilicity and stability, traditional water treatment methods are ineffective in degrading MOX. In this study, a novel S-type heterojunction photocatalyst, In-Ba-10, is introduced which combines barium titanate (BaTiO3) and indium sulfide (In2S3) to address this challenge. The In-Ba-10 catalyst demonstrates excellent photocatalytic performance, with a hydrogen production rate of 2050 µmol g−1 h−1 and a MOX degradation rate constant (k) of 0.049 min−1. Compared to BaTiO3 alone, the performance is enhanced by 48- and 49-fold, respectively. Comprehensive characterization, including Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and electron microscopy, reveals that the S-type heterojunction effectively promotes charge separation and transfer, reduces electron–hole recombination, and improves catalytic efficiency. First-principles calculations further confirm the role of In2S3 as the reduction site and BaTiO3 as the oxidation site. In addition to its high activity, In2S3-BaTiO3 shows stability over multiple cycles, making it a promising candidate for sustainable wastewater treatment. This study highlights the potential of S-type heterojunction photocatalysts for sustainable environmental remediation and energy applications.","PeriodicalId":228,"journal":{"name":"Small","volume":"14 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867231","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}

Current drug delivery systems face challenges in precisely modulating this dynamic microenvironment. Effective inhibition of bone resorption can only be achieved through a strategic response to bacterial infections and inflammation within the periodontal pocket, followed by prompt treatment tailored to disease severity. In this study, tannic acid (TA) is loaded into hollow mesoporous silica nanoparticles (HMSNs) that are functionalized with positively charged polyarginines (R8) and negatively charged human serum albumin (HSA). These HMSNs‐R8@TA‐HSA (HRT) nanoparticles are then encapsulated within an injectable Nap‐Gly‐Phe‐Phe‐Tyr‐OH (NapGFFY) hydrogel (NHRT). The intermediate linker R8 can interact with both arginine gingipain A (RgpA) and reactive oxygen species (ROS), which serve as markers of bacterial infections and inflammation, respectively. HSA, arginine, TA, and nitric oxide are differentially released from the hydrogel in response to varying concentrations of RgpA and ROS, demonstrating excellent antibacterial, antioxidant, and anti‐inflammatory properties.

In this work, four dipodal SAMs are reported based on π‐expanded indolo[2,3‐a]carbazole, incorporated as hole‐selective contacts in iPSCs. The presence of methoxy substituents and the spacer length in SAMs are modified to assess their influence on the device performance. For that, the ITO/SAM and ITO/SAM/PSCs interfaces are characterized in detail, including theoretical studies and analysis of the complete device performance. These results demonstrate the multifactorial effect that SAMs have on the growth of crystalline perovskite and the charge dynamics in the devices. The resulting iPSCs show power conversion efficiency (PCE) between 19.76% and 22.20% with fill factors exceeding 82% in all cases and good stability under continuous illumination. Notably, SAM combining unsubstituted indolocarbazole and longer pentyl spacer (5CPICZ) shows the highest PCE of 22.20%. In contrast, analogous SAMs with propyl spacers (3CPICZ) achiev a PCE of 22.01%. The experimental results reveal that the improved PCE reached with unsubstituted indolocarbazole SAMs is attributed to reduced charge recombination and longer carrier lifetime owing to effective perovskite surface passivation.","PeriodicalId":228,"journal":{"name":"Small","volume":"24 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866652","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, enzyme@cyclodextrin covalent organic framework films are synthesized by template method and further constructed three-dimensional (3D) hydrogen bond-enhanced efficient MXene/enzyme membrane reactor. This strategy provides a spacious microenvironment for the release of enzyme molecules, a simpler process, an easier-to-etch template, a more biocompatible carrier. Furthermore, a versatile platform for interfacial photothermal and fast mass-transfer by constructing films with MXene. The obtained biocatalysts have excellent reusability, high activity and stability, which can be used as efficient biocatalysts for important industrial reactions. The enzyme membrane reactor is constructed by the ‘smart capsule ’ with enzyme@cyclodextrin-COF structure.

However, the discrepancy in binding affinities of catalytic sites to O/H-contained intermediates makes it difficult to achieve OER and HER bifunctional catalysis simultaneously. Multi-component heterostructures have been demonstrated to be an effective solution to realize bifunctional electrocatalysts, but the division of labor and action mechanism of each component are not fully elucidated. Therefore, based on asymmetrical crystal field stabilization energy (CFSE) between NiS and Ni2P, the heterogeneous catalyst (NiS/Ni2P@NF) with built-in electric field (BEF) is constructed in this paper, which showed efficient bifocal water cracking. DFT calculation has confirmed that BEF causes the directional movement of electrons in the material, thus optimizing the OER/HER reaction path. Further control experiments indicated that NiS and Ni2P serves as the active species for the corresponding OER and HER, thus NiS/Ni2P@NF delivers a remarkably reduced cell voltage of 1.62 V (10 mA cm−2) within a H-type electrolyzer as both anode and cathode electrodes. The strategy of constructing BEF based on asymmetrical CFSE has the potential to precisely induce the local electron flow of the catalytic site and accurately design multifunctional catalysts with composition-function contrast.","PeriodicalId":228,"journal":{"name":"Small","volume":"26 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867218","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}

Physically entangled hydrogels provide ideas to solve this problem, but the loss of physical entanglement in the swelling process does not effectively utilize the potential of this approach. In this work, the hydrogel is synthesized including two layers of interpenetrating physically entangled networks, the backbone network and the filler network. According to rubberlike elasticity theory, the backbone network inhibits the swelling of the filler network retaining a large amount of physical entanglements, inheriting and enhancing the advantages of physically entanglement hydrogels. The stiffness of the hydrogel reaches 0.33 MPa, and the fracture toughness reaches 1.93 × 104 J m−2, which shows significant advantages over other hydrogels. The removable physical entanglements tend to favor an ideal uniform network after being subjected to cyclic loading, and the toughness and fracture strain improve more than 2 times to 4.2 MJ m−3 and 7.2, respectively. The fatigue threshold reaches 5.41 × 103 J m−2, which is five times higher than the fatigue-resistant hydrogels.
