However, their lower intrinsic breakdown strength (BDS) frequently results in dielectric breakdown prior to the field-induced phase transition, critically undermining their energy storage performance. Herein, we introduced a high-performance PbHfO3 (PHO)-based AFE ceramic developed through a defect engineering strategy that successfully reduced the concentration of oxygen vacancies within the ceramic via non-equivalent substitution of Ta5+ ions in a high valence state. This approach not only mitigated the leakage current density associated with the migration of free electrons and ions but also improved the electrical homogeneity of the ceramic and curtailed grain growth, culminating in a substantial increase in BDS. Moreover, in terms of microstructure, the local chemical disorder was induced by this method facilitated dipole flipping, resulting in an increased maximum polarization (Pmax) and reduced hysteresis width. Consequently, the (Pb0.97La0.02)(Hf0.6Sn0.4)0.975Ta0.02O3 (PLHST2) ceramic achieved an exceptional energy storage density of approximately 13.15 J cm-3 and a high efficiency of around 83.6% at 680 kV cm-1. This accomplishment not only highlights the considerable potential of PHO-based AFE ceramics for use in pulsed capacitors but also paves the way for future advancements in the energy storage capabilities of dielectric ceramics.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447334","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}

In contrast, tin perovskite solar cells (TPSCs) have been widely recognized as viable alternatives owing to their ideal optical band gap, high carrier mobility and excellent optoelectronic properties. However, TPSCs encounter significant open-circuit voltage (Voc) deficits due to the spontaneous oxidation of Sn2+ and uncontrolled crystallization process. Hence, self-assembled monolayers (SAMs) are now explored as a solution to optimize the perovskite/transport layer interface and improve Voc. Despite the potential advantages and wide applications of SAMs in other optoelectronic devices, their application in TPSCs is relatively scarce. In this review, we elucidated the working mechanism of SAMs in improving device efficiency, summarized the recent progresses, and outlined the challenges in their application in TPSCs. We also discussed strategies for leveraging SAMs to mitigate the Voc deficit in TPSCs. We hope that this review would offer a unique perspective for the ongoing research endeavors focused on the application of SAMs in TPSCs.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447338","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}

Currently, SMs are primarily produced in monoculture settings, devoid of the intricate microbial interactions found in natural environments. Monoculture may lead to the silencing of gene clusters, requiring various genetic or bioprocess strategies to activate the biosynthesis of the corresponding metabolites. Less considered is the effect of monoculture on the efficiency of the production of important, known SMs during microbial fermentations. Co-culturing aims to mimic the complexity of natural microbial habitats, thus may increase the titer, the rate and/or the yield of fermentations. This review summarizes the progress in utilizing co-culture to promote the synthesis of known SMs by describing the types of various microbial co-cultures, listing the mechanisms for enhancing the biosynthesis of SMs, and navigating the challenges and strategies for applying such an approach in the biotechnology industries.","PeriodicalId":94,"journal":{"name":"Natural Product Reports","volume":" ","pages":""},"PeriodicalIF":10.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although drop impact has been studied extensively since high-speed cameras have become available, little is known about drop impact on wedge tips of these structures. Here, we combine experiments and volume-of-fluid simulations to determine how velocity, the sharpness of the structure, and the surface wettability influence the outcome. The central impact of water drops onto wedge tips coated with superhydrophobic nanofilaments or with hydrophobic polystyrene (PS) was imaged. On superhydrophobic surfaces, drops fully rebound or split after impact. On hydrophobic PS surfaces, drops are deposited or split. A critical Weber number (We) was used to describe the transition between deposition/rebounding and splitting. It increases with the top width of the wedge tip and its top angle. The critical We and drop behavior is also affected by wetting properties which determine the drop adhesion and lateral drop friction. Our investigations may help to design new structures to prevent icing or produce tiny drops efficiently in applications.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we report a simple, rapid, and mass-producible method for preparing colored superamphiphobic coatings based on an organic-inorganic hybridization strategy. We employed metakaolin, and nanosilica, combined with organic dyesand modified with fluorosilanes via physical milling, which was subsequently sprayed onto various substrates. By modulating the mass ratio of MK and SiO2, the powders were milled to form a cauliflower-like micro/nanocluster structure, creating an air cushion at the solid-liquid interface. By combining this method with the chemical inertness of fluorosilanes, we achieved a substantial increase in coating durability. The coating maintained a high contact angle and low sliding angle after 48 hours of acid and alkali corrosion and UV irradiation. Additionally, it exhibited low adhesion and good self-cleaning and antifouling properties. Notably, the colored coating retained high color fastness to acidic and alkaline vapors and UV irradiation, demonstrating good durability. It maintained color and wettability after 150 days of outdoor exposure. This coating is available in a variety of colours, compatible with different substrates, suitable for large-scale production and has potential applications in heritage restoration and fresco painting.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447336","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 review aims to highlight recent advances in the synthesis of ICP thin films, with a particular focus on chemical vapor deposition (CVD) technologies. Traditional solution-based methods for ICP thin film deposition face challenges, including non-uniformity, low-throughput manufacturing, and the generation of hazardous wastes. In comparison, CVD eliminates the drawbacks associated with solution-based processes. They offer precise control film properties, including high purity, conformal coating, delicate control over thickness, etc. This review organizes the latest developments in CVD-based ICP synthesis, based on material properties and the synthesis strategy, into direct deposition and post-polymerization modification, ionogels, hydrogels, and ultrathin siloxane or silazane-based polymer films. By providing an up-to-date review of the materials and synthesis, we aim to position CVD polymerization as an effective strategy for future materials development/production and device fabrication in energy, sustainability, and healthcare where ion conductivity is desired.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
