One approach to increase connectivity is to engineer qubit–qubit interactions at a distance. Alternatively, the connectivity can be increased by physically displacing the qubits. For semiconductor spin qubits, several studies have investigated spin coherent shuttling of individual electrons, but high-fidelity transport over extended distances remains to be demonstrated. Here we report shuttling of an electron inside an isotopically purified Si/SiGe heterostructure using electric gate potentials. In a first set of experiments, we form static quantum dots and study how spin coherence decays during bucket-brigade shuttling, where we repeatedly move a single electron between up to five dots. Next, for conveyor-mode shuttling, we create a travelling-wave potential, formed with either one or two sets of sine waves, to transport an electron in a moving quantum dot. This method shows a spin coherence an order of magnitude better than the bucket-brigade shuttling. It allows us to displace an electron over an effective distance of 10 μm in under 200 ns while preserving the spin state with a fidelity of 99.5% on average. These results will guide future efforts to realize large-scale semiconductor quantum processors, making use of electron shuttling both within and between qubit arrays. Conveyor-mode spin shuttling using a two-tone travelling-wave potential demonstrates an order of magnitude better spin coherence than bucket-brigade shuttling, achieving spin shuttling over 10 μm in under 200 ns with 99.5% fidelity in an isotopically purified Si/SiGe heterostructure.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 7","pages":"866-872"},"PeriodicalIF":34.9,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41565-025-01920-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144238001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it remains elusive how transport occurs in biomolecular condensates and how it relates to their dynamic and/or viscoelastic state. We show that the transport of molecules in DNA model condensates does not follow classical Fickian diffusion, which has a blurry front with a square root of time dependence. By contrast, we identify a new type of transport with an ultrasharp front that propagates linearly with time. Our data reveal that this ultrasharp ballistic diffusion front originates from molecular recognition and an arrested-to-dynamic transition in the condensate properties. This diffusion mechanism is the result of intertwining chemical kinetics and condensate dynamics on transport in biomolecular condensates. We believe that our understanding will help to better explain and tune the dynamics and properties in synthetic condensate systems and for biological functions. Adding short, complementary oligonucleotides to single-stranded DNA condensates creates a concentrated, linearly propagating, sharp diffusion front that contradicts the fuzzy concentration gradients and nonlinear kinetics typical of Fickian diffusion.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 8","pages":"1062-1070"},"PeriodicalIF":34.9,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41565-025-01941-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introducing non-Hermiticity gives rise to novel topological phenomena, yet non-Hermitian non-Abelian topological transitions remain experimentally unexplored. In this work we observe a non-Hermitian non-Abelian topological transition in a single electron spin system of a nitrogen vacancy centre in diamond, achieved via a dilation method with a nearby nuclear spin. While this transition cannot be detected by traditional topological numbers, we identify the transition through the measured complex eigenvalue braids. We extract the braid invariants from the relative phases between eigenvalues and thereby establish their changes as clear signatures of non-Abelian transitions. Furthermore we experimentally reveal an intriguing consequence of this transition: the creation of a third-order exceptional point through the collision of two second-order exceptional points with opposite charges. Our work unveils the dynamical interplay between exceptional points and provides guidance on the manipulation of spectral topology to achieve functionalities such as robust quantum control. By means of dilation methods and employing complex eigenvalue braids, non-Hermitian non-Abelian topological transitions are identified, which give rise to a third-order exceptional point.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 7","pages":"873-880"},"PeriodicalIF":34.9,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229270","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}

Current binder identification techniques use a monovalent library of potential binders. Interestingly, proteins on pathogens are often homo-oligomeric—for example, the SARS-CoV-2 spike protein is a homotrimer. Here we describe a simple strategy, MEDUSA (multivalent evolved DNA-based supramolecular assembly), to evolve multivalent assemblies of aptamers with precise interligand spacing and three-fold symmetry, mirroring the geometric structure of many viral capsid proteins. MEDUSA allowed the selection of potent SARS-CoV-2 spike binders structurally distinct from any known aptamers. Decoupling the geometric and structural rigidity contributions toward selectivity made it possible to connect form to function, as demonstrated by the design of tunable fluorescent sensors. This approach offers a blueprint for targeting geometrically defined pathogen structures and developing rapid-response tools for emerging pathogens. Expanding aptamer binder space through tunable directed coevolution of supramolecular scaffolds helps discover nucleic-acid-based multivalent target binders capable of synergistic engagement that cannot be obtained through monovalent selection.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 8","pages":"1087-1097"},"PeriodicalIF":34.9,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41565-025-01939-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, converting CO2 into methane (CH4) kinetically requires the activation of stable CO2 at high temperatures (300–500 °C), while the CO2-to-CH4 conversion thermodynamically favours low temperatures. Here we report an efficient mechanochemical CO2 capture and conversion under mild conditions (65 °C). Using commercial zirconium oxide (ZrO2) and nickel catalysts, the mechanochemical CO2 capture capacity was 75-fold higher than the conventional thermochemical process. The mechanochemical CO2 conversion reached a nearly quantitative CO2 conversion (99.2%) with CH4 selectivity (98.8%). We determined that repeatedly induced abundant oxygen vacancies on ZrO2 by dynamic mechanical actions are responsible for efficient CO2 capture and, thus, subsequently spontaneous methanation. Carbon dioxide can be efficiently captured and converted to methane under mild conditions by a mechanochemical approach that balances the thermodynamics and kinetics of CO2 methanation to simultaneously achieve high CO2 conversion and high CH4 selectivity.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"20 9","pages":"1247-1253"},"PeriodicalIF":34.9,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218779","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 resulting heterogeneity in crystal orientations obscures our understanding of material properties and can reduce the reliability and performance of related applications. Here, using shear stress from an atomic force microscope tip, we ferroelastically write local crystal orientations in oxide thin films. Applying this deterministic and reversible control to SrRuO3 and (La0.7Sr0.3)(Mn0.9Ru0.1)O3 films, we realize twin-free single crystals and design specific crystal-orientation domain textures at the nanoscale. Furthermore, through magnetoelastic coupling, we can mechanically manipulate the local magnetic anisotropy, and thereby write and erase functional nanoscale magnetic textures unattainable by conventional methods. Thus, pure mechanical force emerges as a means to control structural heterogeneity on demand and may make it possible to program electronic and spintronic functionalities.

However, unidirectional guided resonances have been reported only under discrete frequency–wavevector points on a dispersion band, which require accidental interference configurations. Here we show that unidirectional guided resonances can continuously exist across nearly the entire band structure in glide-symmetric bilayer metasurfaces. This continuous excitation of unidirectional guided resonances originates from a synergistic effect between anomalous orthogonality and vertically asymmetric geometry, which is achieved by a Dirac crossing band that preserves glide symmetry. We realize the glide-symmetric bilayer metasurfaces by stacking two WS2 metasurface layers. Angle-resolved emission spectra directly reveal this unidirectional guided resonance continuum. Our work suggests a fundamental solution to existing narrow-band constraints on unidirectional emission and absorption.
