Abstract Diclofenac is a widely used pharmaceutical pollutant that is frequently detected in wastewater and naturalwaters; however, its reliable on-site quantification remains challenging because of costly instrumentation, labor intensive sample preparation, and electrodes with limited electron-transfer efficiency. In this study, we report a simple, scalable, and mask-free strategy for constructing high-performance electrochemical electrodes based on […]

Abstract Flexible electronic platforms require polymer nanocomposites that integrate high optical transparency, tunable photoluminescence (PL), and efficient proton transport. Conventional poly(vinyl alcohol) (PVA) systems often suffer from limited chain mobility and poor nanoparticle dispersion, leading to trade-offs among these properties. To address limitations in conventional PVA systems, namely poor nanoparticle dispersion, limited chain mobility, and […]

Abstract Polyvinyl alcohol (PVA) is valued for its transparency and film-forming ability, but its limited chemical reactivity and weak nanofiller interactions restrict functional tunability. Partially oxidized PVA (OPVA), enriched with ketone and hydroxyl groups, provides a versatile scaffold for nanocomposite design. Transparent OPVA–graphene oxide (GO) films were fabricated via dopant-free aqueous casting with low GO […]

Abstract This study presents a multifunctional hybrid system constructed by interfacing thermally reduced graphene oxide (rGO) nanoflakes with rare-earth-doped Y2O3/ZnO: Er,Yb thin films designed to achieve near-field optical modulation and enhanced charge transport. Here, the rGO layers were deposited by drop-casting exfoliated graphene oxide in isopropyl alcohol. The layers were then thermally annealed at 1000 […]
