We report a facile block copolymer self-assembly approach for fabricating plasmonic Au nanoparticle-decorated WO3 three-dimensional cross-stacked nanowire arrays on microchips for enhanced gas sensing. The porous nanostructure of 3D WO3 NW framework, coupled with the catalytic and surface plasmon resonance properties of Au NPs, synergistically boosts the NO2 sensing performance. The Au/WO3 sensor exhibits an exceptional response of 340.7 to 50 ppm NO2 at 150 °C in dark conditions, which further increases to 980 under white light illumination, along with rapid response/recovery times, a low detection limit, and excellent stability. To elucidate the gas sensing mechanisms, we employ environmental operando micro-spectroscopy techniques, including conductive atomic force microscopy, Kelvin probe force microscopy, and diffuse reflectance infrared Fourier transform spectroscopy. These advanced characterizations, combined with theoretical calculations, provide direct evidence for the efficient generation and transfer of hot electrons from Au NPs to the WO3 NW matrix under light irradiation, revealing their pivotal role in enhancing NO2 adsorption and expanding the electron depletion layer. In-situ measurements also unveil the dynamic modulation of the Schottky barrier height at the Au/WO3 junction, offering deeper insights into the interplay between environmental factors, hot electrons, and resistance alteration in the metal-semiconductor system. This work provides a promising strategy for designing high-performance gas sensors and paves the way for probing complex gas sensing mechanisms.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141018","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, maintaining a high evaporation rate is challenging due to salt accumulation on solar evaporators (SEs), leading to a long-standing trade-off between stable evaporation and salt accumulation in conventional SEs. Inspired by the salt secretion and brine transport mechanisms in mangroves, we present a bio-inspired solar evaporator (BSE) featuring an external photothermal layer and an internal water supply channel. This design enables efficient and continuous evaporation from near-saturated brine using less photothermal material. The BSE exhibits high evaporation performance (3.98 kg m-2 h-1 for 25 wt% brine), effcient salt collection (1.27 kg m-2 h-1 for 25 wt% brine), long-term durability (7 d in 25 wt% brine), and zero liquid discharge desalination. Notably, the BSE achieves a record-high water production rate of 3.50 kg m-2 h-1 in outdoor tests. Furthermore, it can purify World Health Organization-standard freshwater from various types of contaminated water. Importantly, the universality of BSE design is validated by extending it to other solar desalination systems. This work demonstrates a universal SE design, providing key insights into the design of next-generation SEs for efficient and stable evaporation in continuous high-salinity brine desalination.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144179836","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}

Thermochemical and electrochemical methods for reducing CO2 to low-carbon molecules have made significant progress; however, it remains challenging to generate long-chain, structurally diverse carbohydrates, which are the most abundant substances in nature. Here, we report the successful design and realization of in vitro sucrose synthesis from C1 and C3 molecules through a thermodynamically favorable pathway with short reaction steps and low energy input. By engineering the phosphatase and sucrose synthase to improve their catalytic efficiency by 3- to 71-fold, and by optimizing the reaction system through an iterative scanning strategy, we achieved a high conversion yield of 86% and a specific synthetic rate of 5.7 g L-1 h-1. Additionally, we demonstrated the cell-free starch synthesis without the need for dextrin primers, achieving a superior C1-to-starch synthesis rate compared to previously developed multienzyme systems. Building upon this platform, we further extended methanol conversion to a variety of sugars, especially for cellooligosaccharides with a degree of polymerization of Cn≥18. Together, our system provides a promising, plant-independent route for de novo synthesis of structure-diversified oligosaccharides and polysaccharides.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140987","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}

Here, we reveal that persistent Wnt signaling during the peri-implantation stage may be a key obstacle to the implantation of in vitro fertilization (IVF) embryos in a mouse model. Wnt activation affects the deposition of H3K27ac and H3K27me3 on pluripotency genes and bivalent genes, respectively, leading to the abnormal naïve-primed transition and suppressing expression of Otx2 in the epiblast. Furthermore, treatment with the Wnt inhibitor IWP2 promotes the redistribution of histone modifications and gene expression of epiblast. Importantly, Wnt inhibiting significantly improves implantation and intrauterine development of IVF embryos and subsequently ameliorates offspring metabolic abnormalities. Moreover, Wnt inhibiting markedly improves human peri-implantation embryo development and facilitates the transition from a naïve pluripotency state. Our study reveals a novel mechanism underlying the prevention of IVF embryo implantation failure and metabolic disorders in offspring.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144179579","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}

In this study, we present a novel approach utilizing hydrogen-bond-rich covalent organic frameworks (TTP@PVDF50), synthesized through an in situ self-assembly process incorporating polymeric guest species. These covalent organic frameworks (COFs), when integrated into the separators of Li-S batteries, preserve their intrinsic porosity and crystallinity, while the abundant fluorine-rich sites and well-defined pore structures enhance lithium-ion (Li+) transport kinetics. The hydrogen-bond-rich nature of the COFs provides an effective strategy to mitigate the polysulfide shuttle, leveraging both spatial hindrance and strong polar interactions for enhanced adsorption. Density functional theory (DFT) calculations and in situ Raman spectroscopy reveal that the F∙∙∙OH hydrogen bonding network in the TTP@PVDF50 composite significantly accelerates Li+ migration and catalyzes the conversion of LiPSs. The modified separator demonstrates a high discharge capacity of 1420.2 mAh g-1 at 0.2 C (1 C=1675 mAh g-1), alongside remarkable anti-self-discharge performance with only 9.0% capacity loss. Notably, the Li-S battery with a high sulfur loading (4.59 mg cm-2) and a lean electrolyte (6 µL mg-1) retains over 83% of its capacity, underscoring the effectiveness of this strategy in advancing the performance and longevity of Li-S batteries.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075266","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}
