These isomers differ in the position of the redox-active pyridinium core. The aim was to identify the role of core's position in promoting reversible switching between electromers (redox isomers) in solution and at the gold-pyridinium-gold junction circuit. We measured the single-molecule conductance of each pyridinium isomer in various electrolyte environments using tetrabutylammonium salts (TBABF4, TBAPF6, TBABr, and TBACl). The choice of electrolytes played a crucial role in the histograms' shapes-junction distribution, width, and peak position-which act as unique conductance fingerprints for each isomer. During STM-BJ measurements, a dynamic evolution in the conductance histograms was determined, particularly with the electrolytes TBAPF6 and TBABF4. This behavior was attributed to the real-time detection of interactions between the positively charged pyridinium core and the electrolyte anions within the gold-pyridinium-gold junction. The dynamic evolution in single-molecule conductance was rationalized by the Gibbs free energies (ΔG) for the anion-cation pairs obtained from density functional theory (DFT) calculations. Furthermore, the theoretical trend predicted by DFT combined with the Keldysh nonequilibrium Green's function (NEGF) formalism (DFT-NEGF) was consistent with the experimental results.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Catalytic dehydrofluorination of HFC-245fa offers a viable synthesis route for the production of HFO-1234ze(E), but the catalyst degradation under harsh acidic conditions remains a major challenge. In this study, a highly stable γ-Al2O3 supported catalyst was developed for efficient dehydrofluorination with vanadium species exhibiting the highest activity among the screened metal ions Ni2+, V5+, Zn2+, La3+, Fe3+, Mn2+ and Cu2+. The optimized 15 wt% V2O5/γ-Al2O3 catalyst, prepared without oxalic acid assistance, exhibited strong metal-support interactions and demonstrated superior catalytic performance achieving ∼95% HFC-245fa conversion. The catalyst activity increased from 1.3 to 2.1 μmol s-1 gcat-1 due to the formation of in situ VOFx species generated through the interaction between V2O5 and HF, as confirmed from NH3-TPD and XPS analysis. The catalyst also exhibited ∼81% selectivity towards HFO-1234ze(E) at 350 °C. It is noteworthy that the catalyst maintained a stable performance up to 74 h, without significant deactivation. Overall, these results highlight the importance of rational metal selection, loading optimization, and interface engineering in developing robust catalysts for industrial hydrofluoroolefin production.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This methodology allows us to predict fold change values of thousands of differentially expressed genes (DEGs) using a single variable and a single quantitative structure-activity relationship (QSAR) model. In the context of this work, TRI compressed 5167 DEGs into a single variable, explaining 99.9% of the entire transcriptomic space. Further TRI was linked to the properties of inhaled MWCNTs using a nano-QSAR model with statistics R2 = 0.83, QCV2 = 0.8, and Q2 = 0.78, which show a high level of goodness-of-fit, robustness, and predictability of the obtained model. By training a nano-QSAR model on fold changes of thousands of DEGs using a single variable, our study significantly contributes not only to new approach methodologies (NAMs) focused on reducing animal testing but also decreases the amount of computational resources needed for work with complex transcriptomic data. Developed during this work, the software called ChemBioML Platform (https://chembioml.com) offers researchers a powerful free-to-use tool for training regulatory acceptable machine learning (ML) models without a strong background in programming.

However, organic long-chain ligands that modify the surface of QDs hinder charge transfer, thus impairing the performance of QD infrared photodetectors. Here, we report a two-step ligand exchange strategy that decouples the native long-chain ligands from the QDs using specific molecules and then attaches the short-chain ligands, resulting in high response for lead-rich lead selenide (PbSe) QD photodetectors. During the layer-by-layer film deposition process, 1-octanethiol is first used for primary ligand exchange to remove stable ligands, followed by 3-mercaptopropionic acid for secondary exchange to ensure thorough passivation of surface defects. The two-step processing PbSe QD photodetector has a responsivity of up to 1.28 A W-1, a detectivity of 9.65 × 1012 Jones and a record high external quantum efficiency of 144.4% at a bias voltage of 0.5 V at 1100 nm. Benefitting from the high performance, the PbSe QD photodetector can be integrated into a pulse monitoring platform, achieving a physiological sign monitoring by capturing real-time pulse signals of human superficial arteries.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144936700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to conventional 2D COFs that exhibit π-π stacking, this COF adopts an atypical AB stacking mode along the c-axis, resulting in suppressed interlayer π-stacking and enhanced structural regularity. The incorporation of extended π-conjugation through phenazine linkages enables selective interactions with conjugated drug molecules. Among three drug molecules tested-5-fluorouracil, isoniazid, and captopril-the COF demonstrated the highest loading capacity (56 wt%) for 5-fluorouracil, which features a fully conjugated pyrimidine-like ring, followed by isoniazid (54 wt%), which contains a moderately conjugated pyridyl moiety. In contrast, captopril, which lacks significant π-conjugation, showed a lower loading (36 wt%). Our findings underscore the importance of molecular-level π-π interactions in drug encapsulation and highlight how precise framework engineering via π-conjugated building blocks enables conjugation-driven guest affinity, offering key insights and a design blueprint for next-generation conjugated porous frameworks for precision therapeutic delivery.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144936675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the insulating state, the excitation of quasi-bound states in the continuum (Q-BIC) resonance via geometric parameter modulation of silicon pillars is investigated, with its physical mechanism elucidated via impedance matching theory and multipole analysis. This mode demonstrates exceptional sensing performance at 8.017 THz: a refractive index sensitivity of 3.735 THz RIU-1, a quality factor (Q) of 4800.89, and a figure of merit (FOM) of 3822.93 RIU-1. When VO2 is transformed into the metallic state, the device achieves more than 90% ultra-broadband absorption in the range of 3.93 THz to 9.25 THz, and its broadband absorption properties originate from the electric dipole resonance.
