Although predicted for Ni-based systems decades ago, superconductivity was only observed in 2019 in infinite-layer nickelate thin films. More recently, superconductivity with transition temperatures exceeding 80 K was discovered in Ruddlesden–Popper nickelates under high pressure. Despite these advances, both nickelate classes face major experimental challenges in synthesis and sample quality, which limits the application of various experimental techniques needed for a comprehensive understanding of the nature of their superconductivity. In this Review, we summarize recent progress in research on infinite-layer and Ruddlesden–Popper nickelates as well as their structural subcategories, outlining the theoretical foundations and key experimental findings on their electronic and magnetic properties. Additionally, we discuss the major synthesis challenges, identify open questions and future research directions and compare nickelates with other unconventional superconductors, including cuprates and iron pnictides. Nickelates have recently joined the cuprates and iron pnictides as unconventional superconductors with transition temperatures above 80 K. This Review looks for their shared superconducting mechanisms for building a coherent theoretical framework.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"8 2","pages":"70-85"},"PeriodicalIF":39.5,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146148382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The applications of cryo-EM techniques have been extended from structural biology, which mainly focuses on structural information, to materials science, where chemical and physical information are equally important. In this Technical Review, we focus on sample preparation methods and imaging strategies to enable high-resolution imaging of beam-sensitive materials while avoiding electron-beam damage. We also survey emerging methods and applications, with an emphasis on energy materials. This Technical Review highlights advances in cryo-electron microscopy for materials science, covering sample preparation, low-dose imaging and analytical scanning transmission electron microscopy techniques. It discusses strategies to mitigate electron-beam damage and enable high-resolution 2D and 3D imaging of beam-sensitive energy materials.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"8 1","pages":"40-54"},"PeriodicalIF":39.5,"publicationDate":"2025-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145916057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preston, Ulf Zastrau","doi":"10.1038/s42254-025-00893-7","DOIUrl":"10.1038/s42254-025-00893-7","url":null,"abstract":"‘If you can measure it, it is not warm dense matter, and if you can compute it, it is not warm dense matter’ is a tongue-in-cheek aphorism for the peculiar state of matter between condensed matter and hot plasma. It is present in the interior of large planets, in small stars and transiently in inertial confinement fusion concepts. Owing to substantial developments in theoretical methods, computational capabilities and new experimental infrastructures, this definition has now become outdated. Hard X-ray free-electron lasers (XFELs) have proven an especially useful tool to advance the understanding of warm dense matter by allowing precision measurements that can benchmark atomistic simulations and macroscopic models with high resolution in space and time. In this Review, we provide an overview of experimental techniques and summarize the past decade of XFEL research on warm dense matter, which has been dominated by proof-of-principle experiments. Looking forward, we provide an outline of ongoing and expected facility developments in the context of prominent science goals, ranging from astrophysics to new high-performance materials and fusion energy. Warm dense matter — the peculiar state between condensed matter and hot plasma — can be studied with exceptional detail at X-ray free-electron laser facilities. This Review summarizes pioneering experiments and discusses the perspectives for the near and mid-term future.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"8 1","pages":"27-39"},"PeriodicalIF":39.5,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145916063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
