When water flows through 1D or 2D channels, its behaviour deviates substantially from the well-established principles of hydrodynamics. This is because reducing the dimensionality of any interacting physical system amplifies interaction effects that are beyond the reach of traditional hydrodynamic equations. In low-dimensional water, hydrogen bonds can become stable enough to arrange water molecules into an ordered state, causing water to behave not only like a liquid but also like a solid in certain respects. In this Review, we explore the relationship between the molecular ordering of water and its ability to flow in low-dimensional channels, using viscosities of bulk water, vapour, and ice as benchmarks. We also provide a brief overview of the key theoretical approaches available for such analyses and discuss ionic transport, which is heavily influenced by the molecular structure of water. The dynamic interaction between low-dimensional water transport and ion-coupled structural features lies at the heart of recent advances in the design and investigation of angstrom-scale biomimetic and neuromorphic channels. Water’s structure and viscosity change markedly under reduced dimensionality. This Review explores how viscosity depends on the dimensionality of confinement (1D or 2D) and examines the interplay between geometric and ionic constraints in shaping transport properties within angstrom-scale water channels.

Terahertz (THz) technology bridges the gap between electronics and photonics, unlocking transformative opportunities in medical diagnostics, molecular identification and next-generation wireless networks. Usually, THz devices have been made from conventional semiconductors and their heterostructures to achieve the necessary carrier transport properties and optical-to-THz conversion efficiencies. In the past decade, carbon nanomaterials, such as carbon nanotubes and graphene, have been successfully used in the development of THz devices, including emitters, detectors and modulators. These advances are enabled by the unique properties of these materials, including strong linear and nonlinear THz radiation absorption, ultrahigh carrier mobilities and facile gate tunability. In this Review, we present the latest advances in the generation, detection and modulation of THz radiation using carbon nanomaterials, particularly focusing on the use of carbon nanotubes and graphene. The challenges and opportunities of using carbon nanomaterials in THz technology and towards potential applications are discussed. Carbon nanomaterials have strong electron–photon interactions in the terahertz range, gate-tunable photoresponse and high carrier mobilities. This Review provides a discussion of the use of carbon nanotubes and graphene for the generation, detection and modulation of terahertz waves.

Tensor networks have become a useful tool in many areas of physics, especially in quantum information science and quantum computing, where they are used to represent and manipulate quantum states and processes. The original use of tensor networks is the simulation of quantum systems, where tensor networks provide compressed representations of the structured systems. As research into quantum computing and tensor networks progresses, a plethora of new applications are becoming increasingly relevant. This Technical Review discusses the diverse applications of tensor networks to demonstrate that they are an important instrument for quantum computing. Specifically, we summarize the application of tensor networks in various domains of quantum computing, including simulation of quantum computation, quantum circuit synthesis, quantum error correction and mitigation, and quantum machine learning. Finally, we provide an outlook on the opportunities that tensor-network techniques provide and the challenges they may face in the future. Tensor networks provide a powerful tool for understanding and improving quantum computing. This Technical Review discusses applications in simulation, circuit synthesis, error correction and mitigation, and quantum machine learning.

Wetting phenomena have been studied quantitatively for more than 200 years, but there remain many fundamental questions that are not understood. For example, the speed of a water drop sliding down an inclined plane cannot be predicted. A drop that slides down a surface experiences a resistance. We call this resistance drop friction. It is still debated how and where energy is dissipated in a sliding drop. Particularly for the most common liquid, water, there have been considerable advances in the understanding of wetting, driven by the development of new physical, preparative and theoretical methods. Water is a special liquid, owing to its polar nature, its tendency to form hydrogen bonds, the self-ionization into OH− and H3O+, its low viscosity and its high surface tension. In recent years, water–surface interactions due to adaptation, spontaneous electrostatic charging and deformation on elastomers have been identified as important processes that increase drop friction. They may be responsible for drop friction even on seemingly smooth, homogeneous and rigid surfaces. The dynamic wetting of sliding drops, particularly of water, remains poorly understood. New experimental techniques have shown that, in addition to viscous dissipation, other energy dissipation mechanisms such as adaptation, electrostatic charging and deformation can contribute significantly and affect the motion of the drops.

This Review surveys methods that use atomistic simulations to compute solid–fluid surface tension, a key parameter for understanding and controlling physical properties at interfaces. Accurate calculation and understanding of these properties are increasingly important in applications, especially in confined-fluid systems in which surface effects dominate over bulk properties. Traditional approaches such as contact angle measurements, the Wilhelmy plate method, and sessile drop methods often fall short in directly measuring solid–liquid surface tension. By contrast, molecular simulations allow the direct extraction of this parameter, offering a more detailed insight into its behaviour at the nanoscale. The Review emphasizes the challenges associated with solid–fluid interfaces, particularly their anisotropic nature, and discusses computational techniques such as the cleaving method, perturbation approaches and capillary wave theory. This article reviews atomistic methods for computing solid–fluid surface free energy and tension, highlighting challenges from anisotropy. It discusses simulation techniques and methodological developments, and emphasizes the need for improved methods to address complex, confined or disordered systems.

Understanding the atmospheres of exoplanets is crucial for unravelling their formation, evolution and potential habitability. High-resolution cross-correlation spectroscopy (HRCCS) has emerged as a powerful tool for probing exoplanetary atmospheres, enabling the detection of molecular species and the characterization of atmospheric dynamics. However, the reliability of these detections depends critically on the accuracy of laboratory spectroscopic data, particularly precise line positions and the careful statistical treatment of observational data. This Technical Review explores the interplay between laboratory data and high-resolution exoplanet spectroscopy, emphasizing the growing shift from isolated molecular detections to comprehensive whole-atmosphere characterization. We discuss the specific challenges of producing high-quality laboratory data and outline the needs of the exoplanetary community in this context. Key topics include the reliability of HRCCS detections, typical jargon of HRCCS and the ethical considerations in data attribution. By bridging the perspectives of laboratory spectroscopy, quantum chemistry and observational astronomy, we provide recommendations for advancing the field towards a more robust and self-consistent framework for exoplanetary atmospheric studies. Exoplanetary atmosphere studies rely on the quality of laboratory spectroscopy and observational astronomy. This Technical Review highlights the power of high-resolution cross-correlation spectroscopy for advancing the field for all stakeholders.
