However, controllable construction and structure–activity relationships of twinning in electrocatalysts remain formidable challenges. Here, we engineered a lattice-matched Co/CoO heterostructure with enriched twin boundaries through flash Joule heating, where the twins form via lattice matching within homogeneous space groups. XAFS analysis reveals significantly reduced Co coordination numbers in the heterostructure, indicating substantial atomic displacement from the equilibrium positions. The coherent twinning interfaces induce trapped strain, downshifting the d-band center by 0.4 eV and flattening bands near the Fermi level, optimizing the electronic structure for the hydrogen evolution reaction. Consequently, the engineered heterostructure exhibits exceptional performance with an ultralow overpotential of 49 mV at 10 mA cm–2 in alkaline media and remarkable stability over 500 h. Notably, the water splitting can be driven with an ultralow cell voltage of 2.05 V at 1 A cm–2.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"108 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862597","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}

Here we present a class of low-lost, medium-temperature (150 °C), membrane-less aluminum displacement batteries (ADBs) based on a reversible solid-to-solid displacement reaction between transition metals (TM; Fe, Co, Ni) and their chlorides (TMCs) in alkali chloroaluminate molten salts. Crucially, manipulation of the Lewis acidity of the chloroaluminate molten salt electrolyte enables membrane-less operation of the cell by restricting solubility of the TMC and its crosstalk with the Al negative electrode. The structured Ni cathode exhibits a high capacity of 380 mA h g–1, low overpotential of ∼50 mV at the rate of 0.2 A g–1, and high stability over 500 cycles. Furthermore, we demonstrate a membrane-less Al–Fe displacement battery that promises an ultralow-cost avenue for stationary energy storage.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"43 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143858033","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}

By performing transient reflectance spectroscopy in a MoSe2/hBN/WS2 junction, we demonstrate the gate-tunable harvest of hot electrons from MoSe2 to WS2. By spectrally distinguishing hot-electron extraction from lattice temperature increase, we find that electrostatically doped electrons in MoSe2 can boost hot-electron extraction density (nET) by a factor up to several tens. Such enhancement arises from the interaction between hot excitons and doped electrons, which converts the excess energy of hot excitons to excitations of the Fermi sea and hence generates hot electrons. Moreover, nET can be further enhanced by reducing the conduction band offset with an external electric field. Our results provide in-depth insights into the design of HCSCs with electrostatic strategies.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"11 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853548","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}

Employing the purple membrane from Halobacterium salinarum as a test target, we additionally show that the fabrication process results in minimal biomaterial mass loss. Ketene, an unstable intermediate, was identified in the irradiated ice via Fourier transform infrared spectroscopy and is likely an important factor triggering formation of the ethanol-based material.

Exploring novel methods and revealing the fundamental mechanisms for contact engineering are of vital importance for microelectronic devices. Here, the annealing induced interfacial reactions at Cu-ReSe2 contact are dynamically revealed from the atomic scale. Accompanied by the diffusion of Se to Cu, ReSe2 is gradually decomposed to a thin Re interlayer through a “chain-by-chain” manner. Theoretical calculations show that the Cu atoms can facilitate the chemical bond breaking of ReSe2, significantly lowering the Se diffusion energy barrier toward Cu. The formed Re/ReSe2 heterostructure presents a metal-like band structure, which underscores the critical role of Cu in altering the interfacial chemistry and promoting carrier transport across the interface. Our results can provide vital insights into the contact properties of ReSe2 and provide a possible method for fabricating high-performance ReSe2-based devices.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"69 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857806","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}

To optimize their sensitivity, it is crucial to increase the number of spins sampled and maximize their coupling to the detection system without degrading their spin properties. In this paper, we demonstrate enhanced quantum magnetometry via a buried laser-written waveguide in diamond with 4.5 ppm nitrogen-vacancy centers. The waveguide-coupled nitrogen-vacancy centers exhibit spin coherence properties comparable to those of nitrogen-vacancy centers in pristine diamond. Waveguide-enhanced magnetic field sensing is demonstrated in a fiber-coupled integrated photonic chip, where probing an increased volume of high-density spins results in 63 pT·Hz–1/2 of DC magnetic field sensitivity and 20 pT·Hz–1/2 of AC magnetic field sensitivity. This on-chip sensor realizes at least an order of magnitude improvement in sensitivity compared to the conventional confocal detection setup, paving the way for high-sensitivity quantum magnetometry with nitrogen-vacancy ensembles.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"43 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857807","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}
