The development of electrocatalytic systems is currently dependent on the exploration of electrocatalysts with high activity, selectivity, and stability. Metal single-atom catalysts (SACs) have become a new attractive frontier for ammonia electrosynthesis, owing to their maximized atom utilization, unsaturated atom coordination, and tunable electronic structure. In this review, we focused on different metal sites inside the single-atom catalysts and summarized recent advances in SACs for ammonia electrosynthesis. The properties of small nitrogenous substances (including N2, NO, NO2-, and NO3-) are summarized. In addition, the SACs for different catalytic systems are reviewed, with a particular focus on the special and common grounds of metal atom sites. Finally, the perspectives and challenges of SACs for ammonia electrosynthesis are comprehensively discussed, aspiring to provide insights into the development of electrochemical ammonia synthesis.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481806","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}

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}

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}

In this work, a feasible strategy by regulating the precursor composition is introduced to mitigate the defects and impurity phases of Cs3Sb2ClxI9-x films. An optimized content of excess SbI3 in the precursor composition was found to effectively suppress the CsI impurity phases in the obtained Cs3Sb2ClxI9-x films, leading to enhanced crystallinity and reduced defects. Furthermore, the obtained Cs3Sb2ClxI9-x films exhibited an increased dielectric response and reduced exciton binding energy, which are conducive to exciton dissociation and carrier transport. A champion efficiency of 3.42% was achieved with the optimized solar cell devices, which is one of the highest efficiencies reported for all-inorganic antimony-based PSCs. These findings provide new perspectives for exploring high-efficiency antimony-based PSCs.","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":"143447337","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 paper elucidates the diverse landscape of neuromorphic electronic skin (e-skin) technologies while highlighting their numerous applications. Here, neuromorphic devices for e-skin are classified as two types of direct neuromorphic e-skins combining both neuromorphic devices and sensors, and indirect e-skins separating neuromorphic devices and sensors. In direct neuromorphic e-skins, there are developing devices like memristor-based neuromorphic devices with sensors and transistor-based neuromorphic devices with sensors. On the other hand, indirect types are demonstrated as separated neuromorphic and sensor parts systems through the various interfacing structures. It also describes recent neuromorphic developments in artificial neural networks (ANNs), deep neural networks (DNNs), and convolutional neural networks (CNNs), for the real-time interpretation of sensory data. Moreover, it introduces multimodal sensory feedback, soft and flexible e-skins, and more intuitive human–machine interfaces. This review examines various applications, including smart textiles for the development of next-generation wearable bioelectronics, brain-sensing interfaces that enhance tactile perception, and the integration of human-machine interfaces aimed at replicating the biological sensorimotor loop, which can improve health monitoring and biomedical applications. Additionally, the review also highlights the potential of neuromorphic e-skin in human–robot interaction, particularly in the context of continuous prosthetic control and robotics.

However, achieving robust coherent emission, particularly superfluorescence, at room temperature remains challenging due to thermal decoherence. Here, we demonstrate room-temperature tunable coherent emission from perovskite quantum dot (QD) superlattices. Our approach involves the mesocrystallization of CsPbBr3-based QD superlattices driven by oriented attachment, which yields pyramidal-like solids with extended atomic coherency. This level of atomic-scale to nanoscale orientational structure control cannot be realized in previous QD superlattices, and it allows for quantum coherence to persist at ambient conditions. The resulting superlattices exhibit multiple narrowband emissions with exceptional spectral sharpness and tunability, reflecting the collective nature of the coherent emission. Our results establish superlattices as an emerging materials platform capable of robust quantum coherence without cryogenic constraints, opening up new possibilities for quantum optics and nanophotonics applications.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" 8","pages":" 2577-2586"},"PeriodicalIF":12.2,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432073","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 this work, we show for the first time that the mechanical properties of such materials can be mathematically calculated by performing 3D mechanistic modeling on the exact microstructure obtained by non-destructive imaging. Initially, we obtained a digital twin of a monoglyceride-based oleogel from phase-contrast X-ray tomography. The microstructure was found to be composed of an interconnected network of crystalline platelets. Then, we applied micromechanical finite element modeling on the microstructure, which revealed that the effective shear modulus scales with the local solid fraction and also depends on the precise crystalline arrangement. Lastly, we designed composite materials in a digital environment by adding particle inclusions to the digital twin. The particle material, concentration and size are varied to demonstrate their effect on the composite's mechanical properties. The designed materials reveal that particle inclusions can either decrease or greatly increase the shear modulus of lipid-based materials. Our new micromechanical approach accelerates the design of lipid-based materials by leveraging virtual environments, leading the path towards materials with tailored mechanical properties.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432058","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}
