However, the reported centrosymmetric A3Bi2I9 can only operate with external voltage, inevitably resulting in energy consumption and bulky monolithic circuits, limiting their further development. Herein, exploiting the methylhydrazine (MHy) cation with 2s 2 lone-pair electrons (LPEs), a chiral-polarity perovskite MHy3Bi2I9 are obtained and explored its self-powered X-ray detection properties. Where MHy forms the strong hydrogen bond interaction with the inorganic framework, resulting in the asymmetric Bi2I9 unit. Meanwhile, the 2s 2 LPEs contribute to generating MHy dipole moments, leading to spontaneous polarization. On the one hand, spontaneous polarization acts as a driving force to realize the X-ray-generated carriers' separation and transport to acquire self-powered detection ability. On the other hand, the reduced noise current and dark current under zero bias further increase the signal-to-noise ratio and lower the detection limit. Notably, the MHy3Bi2I9 single-crystal-based detector displays a considerable sensitivity (106 μC Gy-1 cm-2) and an ultralow detection limit (55 nGy s-1) in self-powered mode. Herein, new insights for constructing polar lead-free perovskite and realizing unprecedented A3Bi2I9-type self-powered X-ray detectors are provided.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"5 5","pages":"2400508"},"PeriodicalIF":11.1,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12087766/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144112067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, localized plasmon resonances in chemical vapor deposition-grown tungsten disulfide (WS2) nanotriangles, using a combination of advanced spectral analysis and simulation techniques, is investigated. By combining non-negative matrix factorization with electron energy loss spectroscopy, distinct plasmonic modes to provide a comprehensive analysis of the plasmonic landscape of individual and stacked WS2 nanotriangles are identified and characterized. Furthermore, the dispersion relation of these localized plasmon resonances is quantified and their evolution across different WS2 triangular geometries is evaluated. Experimental characterization of plasmonic resonances in WS2 through dedicated numerical simulations based on the pygdm package is validated. The findings highlight the critical role of localized plasmon resonances in modulating the electronic and optical properties of WS2, offering new insights into the design and optimization of TMD-based devices for optoelectronic and nanophotonic applications.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"5 5","pages":"2400558"},"PeriodicalIF":11.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12087782/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144112083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While precious metal catalysts exhibit superior activity, reducing reliance on them is necessary for large-scale applications. To address this, transition metal-based catalysts are studied with strategies to enhance catalytic performance. One promising strategy is heterostructures, which integrate multiple materials to harness synergistic effects. Developing efficient heterostructured electrocatalysts requires understanding their intricate characteristics, which poses challenges. While in situ and operando spectroscopy provides insights, computational materials science is essential for capturing reaction mechanisms, analyzing the origins at the atomic scale, and efficiently exploring innovative heterostructures. Despite growing recognition of computational materials science, standardized criteria for these systems remain lacking. This review consolidates case studies to propose approaches for modeling and analyzing heterostructures. It categorizes heterostructure types into vertical, semivertical, and lateral, defines their characteristics, and propose insights into minimizing or exploiting strain effects from lattice mismatches. Furthermore, it summarizes computational analyses of heterostructure stability and activity across reactions, including oxygen evolution, hydrogen evolution, oxygen reduction, carbon dioxide reduction, nitrogen reduction, and urea oxidation.

Sabatier, CO2 hydrogenation to methane (CO2 methanation) is presently attracting attention as one of the most promising methods for storing intermittent renewable energy in the form of chemical fuels. Ni particles supported by CeO2 constitute a very effective, reliable, and reasonably priced catalyst for CO2 methanation. Recently a new type of CO2 methanation catalyst, consisting of cerium oxide (ceria) nanoparticles doped with nickel (NiCeO x ) in a specific square-planar configuration with an extremely high-Ni mass-specific activity and almost 100% CH4 selectivity, was reported. Here, a 50% enhancement in the CO2 conversion of the NiCeO x catalyst by carefully adjusting the calcination temperature is demonstrated. Notably, thermal aging at 600 °C enhances methanation performance by partially exsolving Ni to the surface, while higher temperatures (750 °C) lead to larger Ni particles, increased CO production, and surface carbon deposition. Several in situ and operando characterization methods are employed to correlate the thermal activation and deactivation of the catalyst with its nanoscale characteristics. Apart from their clear implications for the design of next-generation Ni-based CO2 methanation catalysts, these findings significantly enhance understanding of the complex interplay and nature of various surface sites involved in CO2 hydrogenation.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"5 5","pages":"2400540"},"PeriodicalIF":11.1,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12087771/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144112174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, a single-cell-driven, dual-band metasurface platform is experimentally demonstrated to generate nondiffracting PV beams spanning from UV to visible wavelengths (261-405 nm). The proposed metasurfaces, made of rectangular-shaped silicon nitride nanoantennas, achieve an average transmission efficiency of 65% across dual spectrums.
