The interactions between noble metals and metal oxides as well as their interfaces have been proven to be the origin of their excellent catalytic performance. Deep understandings on the interactions between noble metals and metal oxides at atomic precision, thus to precisely assess their contributions to catalysis, can serve as basic principles for catalyst design. In recent years, polyoxometalates (POMs), which in principle can be regarded as atomically precise metal oxide clusters, have been shown to have strong affinity to noble metals, thus forming diverse kinds of POM-noble metal hybrid clusters. Their well-resolved atomically precise structures and hybrid nature promise them as ideal platforms to understand the interfaces and interactions between noble metals and metal oxides. In this review, metal-metal oxide interface is classified into different categories based on the different configurations of hybrid clusters, and aims to understand the interface structures and electronic correlations between POMs and noble metals at the atomic precision. Based on these basic understandings, the study provides the perspectives on the challenges and research efforts to be paid in the future.","PeriodicalId":228,"journal":{"name":"Small","volume":"178 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673496","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}

Herein, a novel near-infrared II (NIR-II) photo-triggered plasmonic hyperthermia immunomodulator (RP@IR-pcNS@HA nanoparticles (NPs)) for anticancer treatment of both primary and distant cancers is reported. This immunomodulator comprises an IR-1061 dye-encoded NIR-II porous cubic AuAg nanoshell (pcNS) loaded with a Toll-like receptor 7 agonist – R837 in phase change materials (PCMs), further modified with hyaluronic acid (HA). In response to NIR-II photoirradiation, the RP@IR-pcNS@HA NPs controllably deliver and release R837 to tumor sites, subsequently perform plasmonic hyperthermia therapy for direct ablation of primary tumors, and elicit robust anticancer immune responses. It is demonstrated that upon NIR-II irradiation, such a plasmonic hyperthermia immunomodulator combined with anti-programmed death 1 antibody (αPD-1) completely eradicates both primary and distant cancers. In addition, this combination treatment successfully elicits robust immune memory responses for effective suppression of recurrence and distant metastasis of cancer. With the excellent NIR-II surface-enhanced Raman scattering (SERS) detection ability, the RP@IR-pcNS@HA NPs combined with αPD-1 represent an efficient way to develop high-performance theranostic agents for SERS-guided combination cancer photoimmunotherapy.","PeriodicalId":228,"journal":{"name":"Small","volume":"7 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673499","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}

Unfortunately, the existence of toxic lead elements restricts their practical application. Herein, high-quality 1D lead-free crystals Rb2CuX3 (X = Cl, Br) are successfully synthesized in an acidic medium. Rb2CuCl3 and Rb2CuBr3 display violet photoluminescence emission peaks at 401 and 388 nm with a high exciton lifetime of 12.78 and 59.67 µs, respectively, which is due to self-trapped excitons (STE). Furthermore, a photodetector is fabricated to detect harmful UVC radiation with Rb2CuBr3 as a light absorber. The proposed photodetector has a responsivity of 0.92 mA W−1 and a specific detectivity of 1.57 × 109 Jones with a fast response speed of 2.67/2.70 µs for rise/fall time, respectively. In addition, both the samples show good stability against open air, and continuous ultraviolet light (254 nm), as well as good thermal stability which is necessary for device fabrication. Thus, the present study suggests that stable, non-toxic, and environment-friendly Rb2CuX3 (X = Cl, Br) can be a promising candidate for future UVC optoelectronic devices.","PeriodicalId":228,"journal":{"name":"Small","volume":"14 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673429","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}

The direct growth of SWCNT arrays using high-activity metal catalysts is one of the promising methods to approach the mass production of dense SWCNT arrays. However, an inevitable obstacle lies in the post-purification of metal residual. Herein, a sowing strategy to prepare size-tunable potassium chloride (KCl) catalysts for the efficient growth of the SWCNT array with a density of 10 tubes per micron is reported. Through a controllable etching process, numerous surface defects (e.g., vacancies and kinks) are uniformly generated on the substrate as seed pit-like sites for the accommodation and anchoring of catalysts. The well-distributed KCl catalysts with a homogeneous size of ≈1.4 nm enable the growth of ≈1.3 nm SWCNTs through a vapor-liquid-solid mechanism. Importantly, 94 at.% KCl catalysts can be dramatically removed through a simple water-washing process, thus leaving contamination-free SWCNT arrays behind. Interestingly, 85% of nanotubes show metallic properties, which is demonstrated by the combination of electrical characterization and the multi-laser Raman spectroscopy. This sowing strategy contributes to the direct growth of uncontaminated high-density SWCNT arrays.","PeriodicalId":228,"journal":{"name":"Small","volume":"46 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673432","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}

The local charge densities and energy band structures of the neighboring Fe and Te atoms in FeN3-Te are rearranged to facilitate the catalytic conversion of the O-intermediates. Meanwhile, the negative shift of the d-band center in FeN3-Te reduces the energy barrier limit for effective desorption of the final OH* intermediate. In the electrochemical evaluation, Fe1Te1-900 presents a more positive onset potential and half-wave potentials of 1.03 and 0.89 V versus the reversible hydrogen electrode, respectively. Furthermore, the liquid zinc-air batteries assembled with Fe1Te1-900 exhibited excellent performances compared to commercial Pt/C.

However, a comprehensive understanding of ion transport mechanisms, and horizontal and vertical transmission, remains incomplete. By employing a multiscale approach in combination of first-principles calculations and molecular dynamics simulations, the issue of how transmission directions impact on the clay-based 2D nanofluidics on osmotic energy conversion is addressed. It is indicated that the selective and rapid hopping transport of cations in clay-based 2D nanofluidics is facilitated by the electrostatic field within charged nanochannels. Furthermore, horizontally transported nanofluidics exhibited stronger ion fluxes, higher ion transport efficiencies, and lower transmembrane energy barriers compared to vertically transported ones. Therefore, adjusting the ion transport pathways between artificial seawater and river water resulted in an increase in osmotic power output from 2.8 to 5.3 W m−2, surpassing the commercial benchmark (5 W m−2). This work enhanced the understanding of ion transport pathways in clay-based 2D nanofluidics, advancing the practical applications of osmotic energy harvesting.","PeriodicalId":228,"journal":{"name":"Small","volume":"70 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142673433","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}
