This study examines the optical and chemical characteristics of vegetable oils (Dhara; DhVOs, Sunflower; SuVOs and Soyabean; SoVOs) by analyzing parameters such as the absorption coefficient, extinction coefficient, mass attenuation coefficient, total molecular cross-section, functional groups, and zeta potential to evaluate thermal degradation and stability. Samples were collected from the local Kathmandu market, and some were prepared in the laboratory. Analytical techniques included UV–Vis spectrometry, Fourier Transform Infrared (FTIR) spectroscopy, and zeta potential measurements. The absorption coefficient, extinction coefficient, mass attenuation coefficient, and molecular cross-section were evaluated using UV–Vis spectroscopy. Results indicated that all these parameters decreased with increasing wavelength and were affected by thermal exposure. FTIR analysis revealed the presence of key functional groups such as C–H, C–N, C = O, O–H, and N–H. Heating effect was observed to influence these functional groups by causing peak shifts and an increase in the number of peaks, attributed to enhanced molecular vibrations. Zeta (ζ) potential measurements showed a notable reduction in particle size after heating: DhVO decreased from 7.17 nm to 3.54 nm, SuVO from 4.12 nm to 1.97 nm, and SoVO from 69.41 nm to 12.57 nm, along with frequency shifts indicating thermal effects on electric field interactions. The results demonstrate that heating alters molecular structure and enhances colloidal stability. Controlling heating conditions is recommended to optimize oil quality. Future research should investigate the nutritional and health effects of these physicochemical changes.</div></div>","PeriodicalId":100942,"journal":{"name":"Nano Trends","volume":"11 ","pages":"Article 100135"},"PeriodicalIF":0.0,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144831174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hereby, to support the synthesis of new SW-AGNRs, we develop new and efficient principles and rules, based on the fundamental but largely misunderstood concept of (anti)aromaticity. We find that the driving force is increasing global aromaticity (rather than decreasing local antiaromaticity) through preserving the original aromaticity pattern (AP) of the parent alternant AGNR. The resulting APs are practically identical for both open-singlet and triplet states, leading to nearly isoenergetic open shell magnetic states. We uncover that the optimum arrangement of the SW moieties, involving minimum energy cost, is their closer proximity to the “inert” empty rings in the parent AP, which is found identical to the daughter AP, both determined by Z through the generalized rule: <em>Z</em> = 3n, 3n±1 (<em>n</em> = 1, 2…). As proof of concept, we study in detail the SW3×4 and SW4×4, which have similar spintronic, but distinct optoelectronic and structural characteristics. SW4×4, is a better candidate for optoelectronic, in addition to spintronic applications. For the <em>Z</em> = 2 SW2×3AGNRs, which are special cases with mixed and incomplete APs, our current preliminary results suggest possible applications as three-stage magnetic switches (diamagnetic, antiferromagnetic, and ferromagnetic).
