Here, we demonstrate an alternative protocol that exploits dissipative spin dynamics, probed through time-resolved fluorescence, to extract off-axis magnetic field information without relying on spin coherence. The approach operates under continuous optical excitation and leverages spin-dependent transition channels to encode both the strength and orientation of the magnetic field into the fluorescence dynamics. Numerical simulations incorporating Gaussian magnetic noise confirm that the protocol remains robust against spin dephasing, maintaining a stable estimation performance even under short coherence times. We further develop a general parameter estimation framework based on photoluminescence trajectories, enabling off-axis field reconstruction from experimental measurements. The method is experimentally validated and may be adapted to other fluorescence-based spin defect platforms including silicon carbide and hexagonal boron nitride.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"24 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194632","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}

COMSOL simulations reveal that the high-curvature architecture amplifies local electric fields, driving K+ accumulation to stabilize *OCHO intermediates via dipole interactions. The density functional theory also confirms this, showing a reduced *CO2→*OCHO energy barrier. In situ ATR-FTIR captures *OCHO vibrational modes (1575 cm-1) and HCOOH signatures (1695 cm-1).

By integrating aptamers targeting CD3, CD25, and CD122 into a programmable DNA lattice scaffold, ALPHA enables rapid, wash-free, and orthogonal fluorescence activation. Within 30 min, the platform distinguishes resting from activated T cells and generates an Activation Index that strongly correlates with cytokine secretion and cytotoxic function. To directly monitor cytotoxicity, an integrated ATP-responsive aptamer detects extracellular ATP released from lysed targets, enabling real-time assessment of target cell killing.

However, the roles of LiF in the SEI remain elusive. Herein, we examined the evolution of SEI influenced by LiF and identified distinct features that elucidate functional characteristics of LiF for Li metal anodes. Through comprehensive empirical and theoretical analyses, we found that LiF enriches Li2O within the SEI, forms LiF/Li2O interfaces, exhibits non-negligible solubility with spontaneous dissolution-reprecipitation behavior in the electrolyte, and works synergistically with Li2O. These findings shed light on the effects of LiF on Li metal anodes and the arrangement characteristic of LiF within the SEI. By integrating key discoveries regarding LiF, a projected working mechanism for LiF is illustrated.

Here, we demonstrate an optoelectronic platform that combines carrier accumulation/depletion (CAL/CDL) and electrochemical metallization (ECM) effects within a single device. By engineering a Ag/ITO/SiO2/Ag stack and tuning the ITO carrier concentration, we achieve electrically driven transitions between volatile and nonvolatile optical states. Spectroscopic ellipsometry and electrical measurements, enhanced by well-defined optical resonances and a large active area, reveal that low-voltage modulation originates from field-induced carrier redistribution at the ITO/SiO2 interface (CAL/CDL), while long-term optical drift and current evolution are attributed to ECM-mediated silver ion migration and filament formation. The coexistence and controllable interplay of both effects provide a pathway toward multifunctional optoelectronic components capable of operating across distinct memory and modulation modes, with implications for neuromorphic computing and hybrid photonic in-memory computing technologies.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":" ","pages":""},"PeriodicalIF":9.1,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145190450","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}
