Facile voltammetric techniques like linear sweep voltammetry (LSV), differential pulse voltammetry (DPV), and cyclic voltammetry (CV) were employed to study various parameters that influence the efficiency of the fabricated sensor. The exterior structural morphology of bare graphite paste sensor (BGPS) and the electrochemically functionalized poly(glycine)-modified graphite paste sensor (PGMGPS) was studied through Field emission scanning electron microscopy (FE-SEM). Electrochemical impedance spectroscopy (EIS) was applied to evaluate the active surface area of the working sensors. The optimum pH was determined to be 6.0 in phosphate buffer solution (PBS) of 0.2 M concentration. The analysis of potential scan rate variation revealed that the electro-oxidation of AXN on the electrode surface proceeds through diffusion-controlled kinetics with the transfer of two electrons. The limit of detection (LOD) were assessed to be 0.26 µM by CV, 0.24 µM by DPV, and 0.70 µM by LSV techniques, all exhibiting good linearity of oxidation peak current with the varied concentration of AXN. The developed sensor exhibited high selectivity and sensitivity toward the concurrent analysis with rutin (RTN), a flavonoid glycoside. The productivity of PGMGPS was noticed to be unaltered even in the presence of certain interfering metal ions. Furthermore, the stability, reproducible and repeatable attributes of the designed sensor were assessed and the obtained results are in accordance with the required limits. The performed analyses authenticate the proposed PGMGPS as reliable sensor for the quantification of AXN in food samples.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 9","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermal analysis via TGA demonstrated enhanced stability, with the total weight loss decreasing upon filler insertion. The residual mass increased due to the presence of inorganic oxides, with a final residue of 4.9% for pure PVA and increasing with Nb₂O₅ and V₂O₅ doping. Furthermore, optical studies showed an x-axis shifting absorption edge for PVA, which starts at 3.8 eV and lowers to 2.5 eV for PVA-Nb₂O₅-7%V₂O₅ nanocomposite. The indirect band gap decreases for all nanocomposites, reaching 2.85 eV in PVA-Nb₂O₅-7%V₂O₅ nanocomposite, compared to 5.5 eV in PVA. In contrast, the refractive index registers 1.687 in PVA and increases to 2.075 in PVA-Nb₂O₅-7%V₂O₅ nanocomposite. Moreover, dielectric measurements revealed that the dielectric constant rose to 43 in PVA-Nb₂O₅ nanocomposite but fell from approximately 30 for PVA to less than 20 following doping with V₂O₅. The high relative permittivity of Nb2O5 (100) and V₂O₅ (25) suggests their suitability for advanced dielectric applications. AC resistivity measurements showed an increasing trend with frequency, reaching their highest value at PVA-Nb₂O₅-7%V₂O₅.

However, achieving high luminance (≥ 100 lm/W), extended operational lifetimes (≥ 100,000 h), and cost-effective large-scale manufacturing remains a significant challenge. This review examines recent advancements in polymer-based WOLEDs, with a particular focus on semiconductor polymers as next-generation materials for achieving efficient white light emissions. Unlike traditional small-molecule WOLEDs, polymer-based systems offer solution-processable fabrication techniques, such as roll-to-roll printing and inkjet deposition, enabling scalable and cost-effective production. Key innovations discussed include thermally activated delayed fluorescence (TADF) and aggregation-induced emission (AIE) polymers, which enhance efficiency while maintaining spectral stability. Comparative analyses highlight how polymeric architectures can address color instability in multi-emitter systems and synthetic complexity in single-component emitters, positioning them as a more practical alternative for large-area applications. Furthermore, this review bridges the gap between laboratory-scale research and industrial commercialization, outlining strategies to improve charge transport, molecular stability, and device lifetime. Future research directions emphasize scalability, environmentally sustainable fabrication, and integration into next-generation lighting solutions. By evaluating the latest developments and identifying key challenges, this review provides a structured roadmap for advancing WOLED technology from experimental research to real-world applications.

This one-step synthesis of iodine-doped PbSe films enables efficient sensitization, allowing for comprehensive control over dopant concentration. Systematic investigations reveal that iodine doping reduces the bandgap (from 0.317 eV to 0.303 eV), suppresses electron–hole recombination, and extends carrier lifetimes.
