This approach allows precise control over the formation of active iodine-nitrogen coordination sites, significantly enhancing the catalytic performance for H2O2 production via the two-electron oxygen reduction reaction. Among the synthesized catalysts, I-N4 demonstrated superior catalytic activity, achieving a high H2O2 selectivity of 90-96% and a production rate of 1265 mg L-1 h-1 at -0.4 V vs reversible hydrogen electrode. Operando Raman spectroscopy confirmed the dynamic evolution of intermediates during the reaction, while chronoamperometric tests showed long-term stability.

While extensive research has focused on NO2 detection due to its high electron affinity, detecting volatile organic compounds or amine gases by light activation remains challenging because of the high activation energy required for interactions with sensing materials. Here, we report the first demonstration of green-light-activated trimethylamine (TMA) detection using β-In2S3 nanoflakes (NFs) corresponding to the bandgap energy of green wavelength. Photoabsorbed β-In2S3 NFs exhibit a TMA response 55 times greater than that in dark condition, with a rapid detection and ultrahigh selectivity. Density functional theory calculations highlight the role of the intrinsic defective structure of β-In2S3 in gas interactions. The β-In2S3 sensors were successfully applied for real-time fish quality monitoring under humid room-temperature conditions. Our findings provide a material strategy that achieves selective detection of specific gas molecules under wavelength-controlled light activation.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":" ","pages":"11475-11483"},"PeriodicalIF":9.6,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635752","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, controlling such multiple molecular interactions within a single, integrated platform has remained a technical challenge. Herein, we introduce a so-called hybrid-dual-gated voltage-controlled bimodal switch demonstrated on a single MoS2 transistor by cointegrating high-k solid and ionic liquid electrolytes as dual-gate dielectrics. Upon applying the synchronized dual-gate voltages, it results in two distinctive yet interchangeable switching modes: electrostatic near-Boltzmann-limit switching and intercalation-driven metal-insulator transitions. In addition to the improved field-effect switching performances (Ion/Ioff ∼ 109, SSmin ∼ 61 mV/dec) in the low-gate voltage (VG) regime, the steep-slope metal-insulator transitions accompanying 2H-to-1T structural alternations can also be achieved in the high-VG regime. By incorporating conformal electrode passivation and independent dual-gating modulation, the proposed device platform enables highly stable, field-tunable bimodal switching behaviors through broad-range host-guest interactions.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"16 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684420","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, using first-principles GW Bethe-Salpeter equation calculations and symmetry analysis, we demonstrate that the Ti2SiCO2 monolayer hosts out-of-plane bright dipolar excitons with valley-locked and polarization-tunable orientations. These dipolar excitons exhibit valley-selective linear dichroism, high oscillator strengths, and dipole orientations that can be controlled via light polarization. Additionally, a pronounced linear quantum-confined Stark effect is found by using an effective tight-binding model. With long lifetimes, large radii, and substantial binding energies, the dipolar excitons in the Ti2SiCO2 monolayer make it possible to achieve high-temperature excitonic Bose-Einstein condensation and superfluidity, with transition temperatures of 104.3 and 26.1 K, respectively. Our findings establish the Ti2SiCO2 monolayer as a promising platform for exploring tunable correlated excitonic phenomena and designing dissipationless quantum devices.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":" ","pages":"11275-11282"},"PeriodicalIF":9.6,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635749","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}

Herein, we first designed a model micrometer-scale 3D hierarchical FePt catalyst (FePt@3D) system with architecturally tailored supports to amplify interfacial water-catalyst interactions while matching the spatial resolution of magnetic resonance imaging (MRI). Spatiotemporally resolved T2-weighted imaging (T2-WI) revealed that FePt@MP-3D performed water enrichment by 28% through capillary forces and increased tortuosity, corresponding to a low overpotential of 13.8 mV at 10 mA cm-2, surpassing commercial Pt/C (η10 = 14.4 mV). This work establishes MRI as a transformative tool to map spatiotemporal distribution of water molecules at catalytic interfaces, bridging macroscopic water distribution with nanoscale catalytic activity. It is clearly shown that MRI provides a powerful tool for probing the other electrocatalytic reactions (e.g., CO2RR, ORR), where water/ion transfer governs performance.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"10 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693406","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}
