In this work, a novel approach is introduced by integrating the unprecedented trigonal planar MS3 (M = Cd/In, Hg/In) motifs into the nearly optically isotropic tetrahedral units, resulting in two novel chalcogenides CsM2In2S6 (M = Cd/In, 1; Hg/In, 2). Notably, structures 1 and 2 feature nearly planar triangular units at the center, encircled by three trimers, further interconnecting each other to create 3D frameworks. Importantly, phases 1 and 2 display phase-matching (PM) capabilities, primarily attributed to incorporating trigonal planar MS3 units that additionally enhance polarizability anisotropy. Furthermore, compounds 1 and 2 demonstrate moderate second-harmonic generation (SHG) signals (0.70 and 0.84 × AgGaS2@1.7 µm). This study pioneers an efficient strategy for the design of infrared NLO crystals with PM capabilities.","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e2408485"},"PeriodicalIF":13.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666219","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, the cathode materials are still the bottleneck for high-performance ZICs to be achieved. Therefore, ZIF-8-derived porous carbons are one of the most promising candidates but ZIF-8 nanoparticles with different sizes exhibited various electrochemical performances in ZICs. Herein, a series of monodispersed ZIF-8 nanoparticles are first prepared by a temperature-controlled process to fabricate the corresponding ZIF-8-based porous carbon nanoparticles with pre-designed sizes. The as-prepared materials have been tested as cathode materials in ZICs. Thus, their size effect allowed us to disclose its correlation with other factors such as ion transport/storage and capacitance. The results reveal that the optimal-sized porous carbon particles can effectively shorten the ion transport distance and accelerate the ion diffusion rate, resulting in lower electrical resistance, larger ion diffusion coefficients, and faster electron transport. The presented findings can facilitate the design of new advanced cathode materials paving the way for the development of high-performance cathode materials for ZICs in the future.","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e2406187"},"PeriodicalIF":13.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666270","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}

Although these fibers hinder drug penetration and reduce treatment efficacy, the depletion of the collagen matrix is associated with tumor metastasis. To address this issue, epigallocatechin-3-gallate (EGCG) is first exploited for disrupting the dense collagenous stroma and alleviate fibrosis by specifically blocking the TGF-β/Smad pathway in fibroblasts and tumor cells when intraperitoneally administrated in TNBC tumor-bearing mice. A methotrexate (MTX)-loaded dual phosphate- and pH-responsive nanodrug (pHA@MOF-Au/MTX) is next engineered by integrating Fe-based metal-organic frameworks and gold nanoparticles for improved chemo/chemodynamic therapy of TNBC. Surface modification with pH (low)-insertion peptide substantially enhanced the binding of the nanodrug to 4T1 cells owing to tumor stroma remodeling by EGCG. High-concentration EGCG inhibited glutathione peroxidase by regulating mitochondrial glutamine metabolism, thus facilitating tumor cell ferroptosis. Furthermore, sequential EGCG and pHA@MOF-Au/MTX treatment showed remarkable anti-tumor effects in a mouse model of TNBC, with a tumor growth inhibition rate of 79.9%, and a pulmonary metastasis rate of 96.8%. Altogether, the combination strategy developed in this study can improve the efficacy of chemo/chemodynamic therapy in TNBC and represents an innovative application of EGCG.","PeriodicalId":228,"journal":{"name":"Small","volume":" ","pages":"e2406245"},"PeriodicalIF":13.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666233","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}

This study presents an innovative gold-based photocatalyst design utilizing an in situ dopamine polymerization-guided assembly approach for efficient H2 generation via water splitting. By employing gold superclusters (AuSCs; ≈100 nm) instead of ultra-small gold nanoclusters (AuNCs; ≈2 nm) before polymerization, unique nanodisk-like 3D superstructures consisting of agglomerated 2D polydopamine (PDA) nanosheets with a high percentage of uniformly embedded AuNCs are created that exhibit enhanced metallic character post-polymerization. The thin PDA layer between adjacent AuNCs functions as an efficient electron transport medium, directing excited-state electrons toward the surface and minimizing recombination. Notably, the AuSCs@PDA structure shows the largest potential difference (26.0 mV) compared to AuSCs (≈18.4 mV) and PDA NPs (≈14.6 mV), indicating a higher population of accumulated photo-generated carriers. As a result, AuSCs@PDA achieves a higher photocurrent density, improved photostability, and lower charge transfer resistance than PDA NPs, AuSCs, or AuNCs@PDA, with the highest hydrogen evolution rate of 3.20 mmol g−1 h−1. This work highlights a promising in situ polymerization strategy for enhancing photocatalytic hydrogen generation with metal nanoclusters.","PeriodicalId":228,"journal":{"name":"Small","volume":"178 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673506","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}
