Achieving high photocatalytic activity often requires harsh reaction conditions, compromising catalyst stability and longevity. Here we propose a strategy involving polymeric stabilization of photocatalytic centres uniquely localized at the gas–liquid interface, substantially enhancing both the catalytic activity and stability. Applied to the photocatalytic conversion of plastic waste into solar hydrogen, this approach maintained its catalytic performance over 2 months under harsh conditions. Using 0.3 wt% dynamically stabilized atomic Pt/TiO2 photocatalysts and concentrated sunlight, we achieved a plastic reforming activity of 271 mmolH2 h−1 m−2. Scaling to 1 m2 under natural sunlight yielded a hydrogen production rate of 0.906 l per day from polyethylene terephthalate waste. Economic analysis and extensive-scale simulations suggest this strategy as a promising pathway for high-performance, durable photocatalysis, advancing renewable energy conversion.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"218 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144260563","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}

However, atomic-scale manipulation and control of such phases remains elusive. Here we observe the emergent superconductivity and a primary pair density wave at the 2 × 2 Cs reconstructed surface of CsV3Sb5 by means of low-temperature scanning tunnelling microscopy/spectroscopy paired with density functional theory calculations. This quasi-two-dimensional kagome superconducting state with a critical temperature of ~5.4 K is intertwined with the bulk CDW order and exhibits a unique vortex core spectrum and a 4 × 4 pair density wave modulation of the superconducting gap. The emergent phenomena happen at a π-phase-shift dislocation in the periodicity of the CDW along the stacking direction if the 2 × 2 Cs superstructures are out of phase with the bulk CDW. Furthermore, we switched on and off the quasi-two-dimensional superconductivity through tip-assisted atomic manipulation of the 2 × 2 Cs superstructure. Thus, control of the surface reconstruction permits the creation, manipulation and control of quantum many-body states at antiphase boundaries in kagome lattice superconductors and, potentially, in other correlated materials.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"7 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252771","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 receptor-binding domain (RBD) of S adopts two conformations: open and closed, respectively accessible and inaccessible to ACE2. Although these changes surely affect ACE2 binding, a quantitative description of the underlying mechanisms has remained elusive. Here we visualize RBD opening and closing using high-speed atomic force microscopy, gaining access to the corresponding transition rates. We also probe the S/ACE2 interaction at the ensemble level with biolayer interferometry and at the single-molecule level with atomic force microscopy and magnetic tweezers, evidencing that RBD dynamics hinder ACE2 binding but have no effect on unbinding. The resulting modulation is quantitatively predicted by a conformational selection model in which each S protomer behaves independently. Our work thus reveals a molecular mechanism by which RBD accessibility and binding strength can be tuned separately, providing hints to better understand the joint evolution of immune evasion and infectivity.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"90 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252772","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}

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.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"70 1","pages":""},"PeriodicalIF":38.3,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","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":"","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.","PeriodicalId":18915,"journal":{"name":"Nature nanotechnology","volume":"70 1","pages":""},"PeriodicalIF":38.3,"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}
