Specifically, the AV3Sb5 family of materials naturally exhibits a Fermi level close to the Van Hove singularities associated with the saddle points formed from the prototypical kagome band structure. The charge-density wave and superconducting states that form within the kagome networks of these compounds exhibit a number of anomalous properties reminiscent of theoretical predictions of exotic states in kagome metals tuned close to their Van Hove fillings. In this Review, we discuss the key structural and electronic features of AV3Sb5 compounds and survey the status of investigations of their unconventional electronic phase transitions. The family of AV3Sb5 kagome superconductors provides a fascinating platform for the investigation of the interplay between superconductivity and charge-density wave order. This Review discusses the properties of the anomalous charge-density wave and superconducting states observed in these materials and surveys future directions in the study of these and related kagome metals.","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"9 6","pages":"420-432"},"PeriodicalIF":83.5,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140903026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to their soft and water-containing nature, hydrogels are promising materials for applications in many fields, such as biomedical engineering, soft robotics and environmental studies. One of the main obstacles to the practical application of hydrogels is their low mechanical strength and toughness. Since the 2000s, many breakthroughs in the development of mechanically strong and tough hydrogels have led to enormous advances in the study of soft materials and our understanding of their failure mechanisms. Research has also been conducted on long-term mechanical stability — that is, the cyclic fatigue resistance and self-strengthening properties of hydrogels — to enable their application as load-bearing materials. This Review provides a comprehensive overview of the design principles for tough hydrogels. Strategies to obtain self-growing and reinforced hydrogels that can adapt to their surrounding mechanical environment are also presented. Hydrogels are promising in various fields, but improving their mechanical properties is critical for certain applications. This Review comprehensively explores design principles to construct hydrogels with superior mechanical strength, toughness and fatigue resistance, and discusses self-growing and self-reinforced hydrogels.","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"9 6","pages":"380-398"},"PeriodicalIF":83.5,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140881285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extreme reduction of optical mode areas within subwavelength waveguides allows for large enhancements of light–matter interactions resulting in nonlinear phenomena at significantly lower optical powers than their fibre and free-space counterparts. The integration of nonlinear materials into nanophotonics has been instrumental in the practical implementation of emerging applications such as quantum information processing, high-speed optical communications, ultraprecise frequency metrology and spectroscopy. Since the early 2000s, the development of new fabrication methods combined with nanoscale design has led to tremendous improvements in the quality and integration capability of both traditional and new nonlinear material platforms. In this Review, we outline design principles to harness the potential of nonlinear materials on integrated platforms through improvements in waveguide loss, resonator design and dispersion engineering principles. We discuss how these tools have been used towards realizing several of the major goals of integrated nonlinear photonics such as broadband frequency conversion, frequency-comb generation, quantum light sources and nonlinear optical quantum logic gates. Nonlinear optical interactions can be substantially enhanced by the wavelength-scale confinement in integrated photonics, providing transformative capabilities for controlling, enhancing and manipulating material nonlinearities in miniaturized platforms. In this Review, we outline the design principles that harness the potential of nonlinear optical materials on integrated platforms and their utility in applications including broadband frequency conversion, frequency-comb generation, quantum light sources and nonlinear optical quantum logic gates.","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"9 5","pages":"321-346"},"PeriodicalIF":83.5,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140817939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sorption-based atmospheric water harvesting (SAWH) is capable of extracting water vapour using sorbent materials across a broad spectrum of relative humidity, opening new avenues to address water scarcity faced by two-thirds of the population of the world. Although substantial progress has been made, there is still a considerable barrier between fundamental research and real-world applications. In this Review, we provide a multiscale perspective for SAWH technologies that can fill existing knowledge gaps across multiple length scales. First, we elucidate water sorption mechanisms at the molecular level, approaches to understanding sorbent materials, and water transport phenomena. With microscopic insights, we bridge materials innovations to device realization, discuss strategies to enhance device-level sorption kinetics and heat transfer performance, and show that a multiscale design and optimization strategy can lead to a new opportunity space towards system thermodynamic limits. Finally, we provide an outlook for the technoeconomic, social and environmental impact of large-scale SAWH as a global water technology. By bridging materials to devices, we envision that this multiscale perspective can guide next-generation SAWH technologies and facilitate a broader impact on society and the environment. Harvesting freshwater from the air using water sorption materials is an innovative strategy to address water scarcity. This Review offers a multiscale perspective to design the next generation of sorption-based atmospheric water harvesting technology by bridging materials innovations to device realization and provides practical guidelines to understand its real-world impact.","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"9 10","pages":"681-698"},"PeriodicalIF":79.8,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140817966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although Landau level-based flat bands and conventional 3D solids have been pivotal in exploring rich topological phenomena, they are constrained by their limited ability to undergo dynamic tuning. By stark contrast, moiré systems have risen as a versatile platform for engineering bands and manipulating the distribution of Berry curvature in momentum space. These moiré systems not only harbour tunable topological bands, modifiable through a plethora of parameters, but also provide unprecedented access to large length scales and low energy scales. Furthermore, they offer unique opportunities stemming from the symmetry-breaking mechanisms and electron correlations associated with the underlying flat bands that are beyond the reach of conventional crystalline solids. A diverse array of tools, encompassing quantum electron transport in both linear and nonlinear response regimes and optical excitation techniques, provide direct avenues for investigating Berry physics in these materials. This Review navigates the evolving landscape of tunable moiré materials, highlighting recent experimental breakthroughs in the field of topological physics. Additionally, we delineate the most pressing challenges and offer insights into promising avenues for future research. Moiré materials are a versatile and tunable platform that offers a wide variety of lattice constants, energy scales and symmetries, leading to a rich interplay of electron correlations and topology. This Review summarizes recent breakthroughs in topological and Berry physics in moiré materials.","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"9 7","pages":"481-498"},"PeriodicalIF":79.8,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140651680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
