Oxides are integral to heterogeneous catalysis, serving critical roles such as catalyst supports, active materials and electrodes. A highly ordered subset, single-crystalline oxides, have traditionally been used as model catalyst supports in fundamental surface science studies. However, advancements in bulk synthesis have rendered their general use more feasible for real-world applications. In this review, we explore the efficiency of single-crystalline oxides as active metals and supports across a wide range of heterogeneous processes, often performing exceptionally well. Beginning with synthetic methods, we discuss the advantages of single-crystalline oxides in thermo-, electro- and photocatalysis. Previously held conventions about catalytic activity, deactivation and surface–adsorbate interactions are re-evaluated by understanding how these ordered materials behave during the respective reactions. Last, we assess advances in characterization techniques and their impact on designing the next generation of catalysts based on single-crystalline oxides. Single-crystalline oxides offer well-defined surfaces, enabling superior control of their chemistry with tunable catalytic activity and enhanced stability. This review summarizes new advances in their synthesis and analysis, and their prominence in heterogeneous catalysis, namely thermo-, electro- and photocatalysis.
氧化物是多相催化不可或缺的组成部分,扮演着催化剂载体、活性材料和电极等重要角色。一个高度有序的子集,单晶氧化物,传统上被用作基础表面科学研究中的模型催化剂载体。然而,体合成的进步使得它们在现实世界的应用中更加可行。在这篇综述中,我们探索了单晶氧化物作为活性金属和支持物在广泛的异质工艺中的效率,通常表现得非常好。从合成方法入手,讨论了单晶氧化物在热催化、电催化和光催化方面的优点。通过了解这些有序材料在各自反应中的行为,重新评估了以前关于催化活性、失活和表面吸附相互作用的惯例。最后,我们评估了表征技术的进展及其对设计下一代基于单晶氧化物的催化剂的影响。

Planets form and obtain their compositions from the leftover material present in protoplanetary disks of dust and gas surrounding young stars. The chemical make-up of a disk influences every aspect of planetary composition, including their overall chemical properties, volatile content, atmospheric composition and potential for habitability. This Review discusses our knowledge of the chemical and isotopic composition of Solar System materials and how this information can be used to place constraints on the formation pathways of terrestrial planets. We conclude that planetesimal formation by the streaming instability followed by rapid accretion of drifting pebbles within the protoplanetary disk lifetime reproduces most of the chemical and isotopic observables in the Solar System. This finding has important implications for planetary habitability beyond the Solar System because in pebble accretion, volatiles important for life are accreted during the main growth phase of rocky planets as opposed to the late stage. Finally, we explore how bulk chemical inventories and masses of planetary bodies control the composition of their primordial atmospheres and their potential to develop habitable conditions. Leftover materials in protoplanetary disks form planets, shaping their chemistry, atmospheres and habitability. This Review highlights how planetesimal formation and pebble accretion explain planetary compositions, influencing volatile delivery and atmospheric development, with implications for planetary habitability beyond our Solar System.
行星的形成和组成来自于围绕着年轻恒星的尘埃和气体的原行星盘中的剩余物质。圆盘的化学组成影响行星组成的各个方面,包括它们的总体化学性质、挥发性含量、大气组成和可居住性的潜力。这篇综述讨论了我们对太阳系物质的化学和同位素组成的了解,以及如何利用这些信息来限制类地行星的形成途径。我们得出的结论是,在原行星盘的生命周期内,由流不稳定性和漂流卵石的快速吸积引起的星子形成再现了太阳系中大部分可观测到的化学和同位素。这一发现对太阳系以外行星的可居住性具有重要意义,因为在鹅卵石吸积中,对生命重要的挥发物是在岩石行星的主要生长阶段而不是后期阶段被吸积的。最后,我们探讨了行星体的大量化学库存和质量如何控制其原始大气的组成及其发展可居住条件的潜力。

Co-solvent strategy for rechargeable post-lithium metal batteries 可充电后锂金属电池的共溶剂策略。
IF 51.7 1区 化学 Q1 CHEMISTRY, MULTIDISCIPLINARY Pub Date : 2025-04-28 DOI: 10.1038/s41570-025-00714-6

The potential increase in cost of lithium-ion batteries owing to the limited supply of lithium has prompted investigations into alternative and complementary rechargeable batteries that use post-lithium charge carriers with higher elemental abundance. However, achieving highly reversible post-lithium metal anodes with sufficient kinetics remains challenging. The addition of co-solvents to conventional electrolytes is emerging as an important strategy to resolve these issues. In this Perspective, we discuss the progress of the co-solvent strategy for sodium, potassium, magnesium, calcium, zinc and aluminium post-lithium metal batteries. The coordination ability of co-solvents with post-lithium charge carriers is presented as a useful guide for selecting co-solvents for the respective battery electrolytes, owing to its correlation with several influential factors that affect the electrochemical performance of the metal anodes, such as solvation structure, de-solvation process and solid electrolyte interphase formation. Additionally, a discussion is provided on the importance of unravelling the effects beyond the solvation sheath of cationic charge carriers and for the development of sustainable electrolytes. The coordination ability of co-solvents with cationic charge carriers is discussed as a guide for selecting co-solvents for various post-lithium metal batteries. Effects beyond the solvation sheath of cationic charge carriers and the sustainable development of electrolytes are necessary for improving batteries in the future.
由于锂供应有限,锂离子电池的成本可能会增加,这促使人们研究使用元素丰度更高的后锂电荷载体的替代和互补可充电电池。然而,获得具有足够动力学的高可逆后锂金属阳极仍然具有挑战性。在传统电解质中添加共溶剂是解决这些问题的重要策略。本文主要讨论了钠、钾、镁、钙、锌、铝后锂金属电池的共溶剂策略的研究进展。共溶剂与后锂载流子的配位能力与影响金属阳极电化学性能的几个因素(如溶剂化结构、脱溶剂化过程和固体电解质间相形成)相关,可以作为选择电池电解质共溶剂的有用指南。此外,还讨论了揭示阳离子载流子溶剂化鞘之外的影响以及开发可持续电解质的重要性。

Self-healing crystals 自愈的晶体
IF 51.7 1区 化学 Q1 CHEMISTRY, MULTIDISCIPLINARY Pub Date : 2025-04-14 DOI: 10.1038/s41570-025-00706-6

Self-healing is an intrinsically exciting concept as it applies to the process of recovery, a commonplace phenomenon found in living organisms. Self-healing of artificial materials is as beneficial to living creatures as it is to materials science, wherein the effect can considerably prolong lifetimes. Although self-healing sodium chloride crystals were discovered in the 1980s, the field entered a renaissance when healing was observed in the emerging materials class of molecular crystals in 2016. Self-healing properties in polymers, cementitious materials, and coatings have already found commercial applications. The reinvigorated interest in self-healing molecular crystals stems from their prospects as durable, lightweight and flexible emissive or electronic materials. Ideally being defectless and ordered media, organic crystals have unique optical, mechanical and electrical properties, and the possibility of self-healing substantially increases their viability for smart devices. Self-healing crystals are an emerging class of materials that are highly responsive to dynamic stimuli. This Perspective gives an overview of the field since its inception, highlights current design principles, and discusses the methodologies used to characterize healed crystals.
自我修复是一个本质上令人兴奋的概念,因为它适用于恢复过程,这是在生物体中发现的一种常见现象。人造材料的自我修复对生物和材料科学都是有益的,其效果可以大大延长寿命。虽然自修复氯化钠晶体早在20世纪80年代就被发现,但当2016年在新兴材料类分子晶体中观察到自修复后,该领域进入了复兴时期。聚合物、胶凝材料和涂料的自修复特性已经找到了商业应用。对自我修复分子晶体重新燃起的兴趣源于它们作为耐用、轻便和灵活的发射或电子材料的前景。理想情况下,有机晶体是无缺陷有序的介质,具有独特的光学、机械和电学性能,并且自我修复的可能性大大增加了它们在智能设备中的可行性。

Kinetics and dynamics of oligonucleotide hybridization 寡核苷酸杂交的动力学和动力学

The hybridization of short nucleic acid strands is a remarkable spontaneous process that is foundational to biotechnology and nanotechnology and plays a crucial role in gene expression, editing and DNA repair. Decades of research into the mechanism of hybridization have resulted in a deep understanding of its thermodynamics, but many questions remain regarding its kinetics and dynamics. Recent advances in experiments and molecular dynamics simulations of nucleic acids are enabling more direct insight into the structural dynamics of hybridization, which can test long-standing assumptions regarding its mechanism. In this Review, we summarize the current state of knowledge of hybridization kinetics, discuss the barriers to a molecular description of hybridization dynamics, and highlight the new approaches that have begun uncovering the dynamics of hybridization and the duplex ensemble. The kinetics and dynamics of hybridization are highly sensitive to the composition of nucleic acids, and we emphasize recent discoveries and open questions on the role of nucleobase sequence and chemical modifications. This Review summarizes the current state of knowledge of DNA and RNA oligonucleotide hybridization kinetics, discusses new insights into the dynamics of hybridization and the duplex, and highlights strategies to probe hybridization at a deeper molecular level.
核酸短链杂交是一种显著的自发过程,是生物技术和纳米技术的基础,在基因表达、编辑和DNA修复中起着至关重要的作用。几十年来对杂化机理的研究使人们对其热力学有了深刻的认识,但在动力学和动力学方面仍存在许多问题。核酸实验和分子动力学模拟的最新进展使我们能够更直接地了解杂交的结构动力学,这可以检验长期以来关于其机制的假设。在这篇综述中,我们总结了杂化动力学的现状,讨论了杂化动力学分子描述的障碍,并强调了已经开始揭示杂化动力学和双系系综的新方法。杂交的动力学和动力学对核酸的组成高度敏感,我们强调最近的发现和关于核碱基序列和化学修饰作用的开放问题。

Multifaceted nature of defect tolerance in halide perovskites and emerging semiconductors 卤化物钙钛矿和新兴半导体中缺陷容忍度的多面性
IF 51.7 1区 化学 Q1 CHEMISTRY, MULTIDISCIPLINARY Pub Date : 2025-04-07 DOI: 10.1038/s41570-025-00702-w

Lead halide perovskites (LHPs) have shot to prominence as efficient energy-conversion materials that can be processed using cost-effective fabrication methods. A reason for their exceptional performance is their crystallographic defect tolerance, enabling long charge-carrier lifetimes despite high defect densities. Achieving defect tolerance in broader classes of materials would impact on the semiconductor industry substantially. Considerable efforts have been made to understand the origins of defect tolerance, so as to design stable and nontoxic alternatives to LHPs. However, understanding defect tolerance in LHPs is far from straightforward. This Review discusses the models proposed for defect tolerance in halide perovskites, evaluating the experimental and theoretical support for these models, as well as their limitations. We also cover attempts to apply these models to identify materials beyond LHPs that could exhibit defect tolerance. Finally, we discuss the experimental methods used to understand defects in mixed ionic–electronic conductors, as well as the important information that is necessary for a deeper understanding, in order to develop improved models that enable the design of defect-tolerant semiconductors. Defect tolerance is a key factor behind the exceptional optoelectronic properties of lead halide perovskites, but it is not well understood. This Review discusses the models for defect tolerance and what has been learnt in generalizing these models to lead-free, stable materials.
卤化铅钙钛矿(LHPs)作为一种高效的能量转换材料,可以使用成本效益高的制造方法进行加工。其优异性能的一个原因是其晶体缺陷容忍度,尽管高缺陷密度,仍能实现长载流子寿命。在更广泛的材料类别中实现缺陷容忍度将对半导体工业产生重大影响。为了设计出稳定、无毒的lhp替代品,人们已经做出了相当大的努力来了解缺陷耐受的起源。然而,理解lhp中的缺陷容忍度远非易事。本文讨论了目前提出的卤化物钙钛矿缺陷容限模型,评估了这些模型的实验和理论支持,以及它们的局限性。我们还介绍了应用这些模型来识别可能表现出缺陷容忍度的lhp以外的材料的尝试。最后,我们讨论了用于理解混合离子-电子导体中缺陷的实验方法,以及深入理解所必需的重要信息,以便开发改进的模型,使设计耐缺陷半导体成为可能。

Supramolecular approaches for the treatment of hypoxic regions in tumours 治疗肿瘤缺氧区的超分子方法
IF 51.7 1区 化学 Q1 CHEMISTRY, MULTIDISCIPLINARY Pub Date : 2025-04-04 DOI: 10.1038/s41570-025-00705-7

Supramolecular chemistry provides a range of ‘weak’ intermolecular interactions that allow drugs and prodrugs to self-assemble. In the complex biological setting of blood and tumours, these interactions must be stable enough for efficient and selective drug delivery to the tumour site, but weak enough to allow the release of the cytotoxic load. The non-covalent nature of supramolecular interactions enables the detachment of smaller (pro)drug monomers that can penetrate cancer cells differently to the original nanoparticles. Hypoxic tumours show low oxygen levels due to poor vascularization, which poses challenges for drug delivery and generates biological resistances. Supramolecular building blocks specifically designed for hypoxic tumours offer targeted activation of prodrug self-assemblies, enhancing effectiveness against hypoxic cancer cells and hypoxic regions in tumours. This Review explores how supramolecular chemistry can improve (pro)drug delivery and activation in hypoxic tumours. Hypoxic tumours present considerable challenges in cancer treatment owing to their specific chemistry, biology and physics, which leads to resistances to conventional therapies. This Review explores innovative strategies based on supramolecular chemistry to overcome these obstacles and discusses future research directions that might help translating supramolecular approaches to the clinics.
超分子化学提供了一系列“弱”分子间相互作用,使药物和前药能够自组装。在血液和肿瘤的复杂生物学环境中,这些相互作用必须足够稳定,以便有效和选择性地将药物递送到肿瘤部位,但又必须足够弱,以允许释放细胞毒性负荷。超分子相互作用的非共价性质使得更小的(原)药物单体能够脱离癌细胞,与原始纳米颗粒不同。缺氧肿瘤由于血管化不良而表现出低氧水平,这给药物递送带来了挑战,并产生了生物耐药性。专为缺氧肿瘤设计的超分子构建块提供靶向激活前药自组装,增强对缺氧癌细胞和肿瘤缺氧区域的有效性。这篇综述探讨了超分子化学如何在缺氧肿瘤中改善(促进)药物传递和激活。

This Review explores innovative strategies based on supramolecular chemistry to overcome these obstacles and discusses future research directions that might help translating supramolecular approaches to the clinics.","PeriodicalId":18849,"journal":{"name":"Nature reviews.
