One of the major reasons for limited therapeutic efficacy is the poor penetration of drugs across the blood–brain barrier. Despite the development of multiple drug delivery platforms, the overall drug accumulation in the brain remains sub-optimal. Another critical but overlooked factor is achieving precision delivery to a specific region and cell type in the brain. This specificity is crucial because most neurological disorders exhibit region-specific vulnerabilities. Multiple trials have failed owing to adverse CNS effects induced by nonspecific drug targeting. In this Review, we highlight the key regions and cell types that should be targeted in different CNS diseases. We discuss how physiological barriers and disease-mediated changes in the blood–brain barrier and the overall brain can impact the precision delivery of therapeutics via the systemic route. We then perform a systematic analysis of the current state-of-the-art approaches developed to overcome these barriers and achieve precision targeting at different levels. Finally, we discuss potential approaches to accelerate the development of precision delivery systems and outline the challenges and future research directions. The development of therapeutics for central nervous system disorders suffers from high failure rates owing to poor blood–brain barrier penetration and lack of targeted delivery. This Review discusses how nanoparticles can help to overcome these challenges to enable precision targeting of the brain for different central nervous system diseases.","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"9 8","pages":"567-588"},"PeriodicalIF":79.8,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141453152","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}

CO2E performance at the laboratory scale is advancing quickly, including ongoing scale-up and industrialization efforts. To address global CO2 emissions (~37 Gt per year), CO2 electrolysers and components, as well as upstream and downstream associated technologies, must be deployed at the gigawatt scale. This entails considerable challenges beyond performance, such as resource availability, deployment readability and end-of-life system management, which are today overlooked. In this Review, we analyse the impending resource challenges as CO2E deployment approaches gigatonne scale, considering a life cycle assessment focused on the associated materials and their corresponding global warming impact. We identify scalability bottlenecks related to membranes, electrode supports and anode materials, among others, and discuss the need for more stable carbon-efficient systems and materials recycling strategies. We conclude with potential approaches to rationally design materials towards sustainable CO2 capture and electrolysis at the gigatonne scale. CO2 electroreduction aims to decarbonize converting CO2 and clean energy into chemicals. To have an impact, this technology should be scaled up into the gigatonne conversion range. In this Review, the authors analyse challenges related to resource and material scalability bottlenecks to enable the sustainable deployment of CO2 electroreduction.","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"9 8","pages":"535-549"},"PeriodicalIF":79.8,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141448138","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}

A confluence of these two themes is engineered in moiré materials, an emerging class of highly tunable, strongly correlated 2D materials designed by the rotational or lattice misalignment of atomically thin crystals. In moiré materials, dominant Coulomb interactions among electrons give rise to collective electronic phases, often with robust topological properties. Identifying the mechanisms responsible for these exotic phases is fundamental to our understanding of strongly interacting quantum systems and to our ability to engineer new material properties for potential future technological applications. In this Review, we highlight the contributions of local spectroscopic, thermodynamic and electromagnetic probes to the budding field of moiré materials research. These techniques have not only identified many of the underlying mechanisms of the correlated insulators, generalized Wigner crystals, unconventional superconductors, moiré ferroelectrics and topological orbital ferromagnets found in moiré materials, but have also uncovered fragile quantum phases that have evaded spatially averaged global probes. Furthermore, we highlight recently developed local probe techniques, including local charge sensing and quantum interference probes, that have uncovered new physical observables in moiré materials. Moiré materials are an emerging class of strongly correlated quantum materials designed by the rotational or lattice misalignment of 2D crystals. This Review discusses how local probe techniques are uniquely positioned to elucidate the microscopic mechanisms underlying the electronic phases in moiré materials.","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"9 7","pages":"460-480"},"PeriodicalIF":79.8,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141182487","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}
