We observe signatures of Aharonov-Bohm (AB)-type oscillations for 0.32 ≤ x ≤ 0.51, which coexist with aperiodic universal conductance fluctuations (UCFs) and are consistent with phase-coherent transport on the nanowire surface. We separately analyze the temperature dependence of the AB-type oscillations and UCFs. The oscillations give a phase coherence length of lϕ = 1.4 ± 0.2 μm at 80 mK, consistent with the ballistic transport regime. The UCF provides a significantly smaller lϕ, consistent with a diffusive bulk transport channel, parallel to the ballistic surface.

The exceptional stability of CSC─including high mechanical strength, wide pH tolerance, and suppression of hydrogen evolution─combined with high zinc ion migration number (tZn2+ = 0.70), leads to its remarkable electrochemical performance. The cycle life of Zn//Zn batteries with CSC is over 6400 and 400 h at 5 mA cm–2 and 20 mA cm–2, respectively. A Zn//MnO2 full battery exhibits 92.85% capacity retention after 10000 cycles at 5 A g–1 (∼16C), significantly outperforming the widely used commercial separators in AZIBs like glass fiber (GF).

Herein, we proposed a surface-engineering strategy to endow GFET arrays with antifouling robustness and molecular-sieving selectivity. Two fluorine-rich covalent organic framework (F-COF) films synthesized at the liquid–liquid interface were transferred onto GFET channels through a gentle, solvent-free lamination protocol, creating F-COF/GFET sensors with high transconductance and typical bipolar characteristics of graphene. F-COF films in the modified GFET sensors functioned as size-selective gates for smaller metal ions (e.g., divalent cations like Zn2+), but excluded anionic methyl orange and larger cationic Rhodamine B. The F-COF/GFET sensors reduced the nonspecific protein adsorption and allowed the detection of Ca2+ at low concentrations (10–6 M) when exposed to a simulated physiological milieu containing 10–4 M bovine serum albumin. Decoupling antifouling from recognition at the monomer level provides a generalizable strategy for selective, real-time GFET biosensors in biofluids.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"103 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145229456","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}

Conductivity measurements, varying the thickness of the LNO channel, show that this phenomenon is confined to a few atomic layers at the interface. Combining in situ biasing and off-axis holography, we mapped out electrostatic potentials at the PbZr0.2Ti0.8O3(PZT)/LNO/SrTiO3(STO) heterostructure upon polarization switching. Using aberration-corrected STEM, the interfacial atomic structures were investigated for the two different PZT polarization states. Polarization in PZT induces a significant change in the in-plane O–Ni–O bond angles, with a 37° modulation in the topmost 1 or 2 LNO unit cells, driven by strain in the oxygen sublattice for the two opposite polarization directions in PZT. Both oxygen and cation sublattices exhibit strain responses exceeding 10% upon switching. This atomic-layer structural modulation highlights a mechanism for functional oxide heterostructure development, offering pathways for advancements in nonvolatile memory, sensors, and energy-efficient transistors.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"21 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236058","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 height perturbation and lattice perturbation affect the out-of-plane and in-plane mode couplings, respectively, contributing to tailoring the Q factor and regulating the angle dispersion. We have demonstrated an infrared emitter, compatible with wavelength tunability and large-scale on-chip fabrication, exhibiting a high Q factor of up to 650 and superior angle-insensitive performance over the full angle range.
