Herein, this study presents a pathogen-responsive piezoelectric heterojunction ZnO@Viologen-covalent organic frameworks (COF) (ZVP) that enables selective modulation of skin microbiota based on bacterial redox characteristics. The ZVP undergoes a structural transformation from ZVP to Re-ZVP, triggered by the respiration activity of Cutibacterium acnes (C. acnes), which enhances its piezo-phototronic properties, while remaining unreactive to commensal bacteria such as Staphylococcus epidermidis (S. epidermidis). This transformation induces a surface charge imbalance in ZVP, thereby boosting the piezo-phototronic effect with a piezoelectric coefficient (d33) surge from 41 to 171 pm V-1. Concurrently, Re-ZVP exhibits a 166% increase in a higher rate of reactive oxygen species (ROS) generation than ZVP under the synergy of light and ultrasound. This amplified ROS production selectively disrupts C. acnes metabolism without compromising beneficial microbes. In an acne model in mice induced by C. acnes, ZVP demonstrates potent in vivo antibacterial activity against C. acnes and effectively attenuates pathogen-driven inflammation induced by C. acnes. By leveraging bacterial redox heterogeneity, this study pioneers a smart microbial regulation strategy through pathogen-activated piezo-photocatalysis, offering a novel means for targeted microbiota modulation.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145205054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, realizing large-grained and preferentially oriented perovskite crystals remains particularly challenging in printable mesoscopic architectures. Herein, we present a liquid-metal-enabled heteroepitaxial strategy to regulate MAPbI3 crystallization on Ga2O3 surfaces derived from Ga nanodroplets. Structural modeling and atomic-resolution transmission electron microscope (TEM) analysis reveal an exceptional lattice match between the (110) planes of MAPbI3 and the exposed Ga2O3 facets, with an ultralow mismatch of merely 0.32 %. This near-perfect lattice alignment drives the formation of orientation-controlled MAPbI3 crystals within the mesoporous scaffold. Moreover, the epitaxial interface establishes type-II band alignment that accelerates charge extraction while suppressing interfacial recombination. The resultant printable mesoscopic perovskite solar cells achieve a champion power conversion efficiency (PCE) of 20.2 % (AM1.5G), representing a 16 % enhancement over conventional non-epitaxial counterparts. Crucially, the devices demonstrate exceptional operational stability, retaining 97 % of initial PCE after 3000 h of maximum power point tracking under harsh conditions (55 ± 5 °C, 85 % RH).","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review focuses on the transformation of CO2 and N2, highlighting their significance in green chemistry. We begin by discussing the fundamental principles of green chemistry and the advantages of utilizing CO2 and N2 to mitigate greenhouse gas emissions and reduce reliance on fossil resources. Subsequently, the review examines advanced transformation pathways for CO2 conversion, including electrocatalytic reduction, photocatalytic processes, and thermochemical transformations, evaluating their efficiency and scalability. The reduction of N2 and nitrogen oxides (NOx) to ammonia (NH3) is explored, presenting innovative alternatives to the traditional Haber-Bosch process that offer improved energy efficiency and lower environmental impact. Furthermore, the synthesis of nitrogenous compounds beyond NH3 is discussed, highlighting the versatility of green NH3 in the production of diverse chemicals. A key focus is placed on integrating CO2 and N2 transformations through CN coupling reactions, enabling the direct formation of organic molecules with reduced environmental footprints. The review concludes by identifying current challenges and future directions, emphasizing the potential of catalytic technologies to foster a sustainable and resilient chemical industry.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145079301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lithium metal batteries often have high energy density but poor cycle stability, while graphite (Gr)-based batteries usually have long cycle life but are limited in energy density. Therefore, mixing lithium with Gr as the anode is expected to balance high energy density and long cycle life. Reducing the negative/positive areal capacity (N/P) ratio to less than 1 is the simplest means to achieve a hybrid anode. The battery with sulfurized poly(acrylonitrile) (SPAN) as the cathode and an ultra-low N/P ratio (N/P = 0.6) is expected to leverage the significant advantage of its cathode's energy density far exceeding that of traditional cathodes, while maintaining stable cycling performance. This makes it a highly promising battery system. Through the design of anion-mediated electrolyte engineering, the capacity retention rate of the SPAN||Gr pouch cell at N/P = 0.6 after 300 cycles was 92 %, and its energy density was increased by 24 % compared with that at N/P = 1.1, achieving a balance between energy density and cycling stability. This strategy establishes N/P engineering coupled with electrolyte design as a scalable paradigm for next-generation energy-dense batteries.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For further improvements in stability, increasing the cavity length at few-kelvin temperatures provides a promising alternative to utilizing relatively short cavities with novel coating, but has yet to be demonstrated with state-of-the-art stability. Here we report on the realization of a relatively long ultra-stable silicon cavity with a length of 10 cm and sub-5-K operating temperatures. We devise a dynamical protocol of cool-quiet quench measurement that reveals the inherent 10-17-level frequency instability of the silicon cavity despite the substantially larger frequency noise induced by the cryostat vibration. We further develop a method for suppressing the cryostat-vibration-induced frequency noise under continuous cooling, and observe an average frequency instability of 4.3(2)×10-17 for averaging times of 4 to 12 s. Using the measured noise power spectral density, we compute a median linewidth of 9.6(3) mHz for the silicon cavity laser at 1397 nm, which is supported by an empirically determined linewidth of 5.7(3) mHz based on direct optical beat measurements. These results establish a new record for optical cavities within a closed-cycle cryocooler at sub-5-K temperatures and provide a prototypical system for using long cryogenic cavities to enhance frequency stabilities to the low-10-17 or better level.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145051485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
