This format of electrochemical indicator has potential applications in a broad range of commercial sectors, including authenticity labeling, healthcare, food packaging, and logistics. However, there is limited work exploring how polymer gel electrolytes, which are commonly employed in flexible electrochemical devices, influence the electropolymerization process. Here, we study the electrochemical polymerization of 3–4-ethylenedioxythiphene (EDOT) in a UV-curable ethylene oxide-propylene oxide-allyl glycidyl ether (EO-PO-AGE) polymer gel electrolyte. Using potential step methods and cyclic voltammetry, we find that the addition of the polymer gel matrix lowers the overpotential required for film formation by 0.1 V compared to the liquid electrolyte. Furthermore, indicators with the polymer gel electrolyte show an increase in coloration efficiency, and greater visual homogeneity compared to indicators with the liquid electrolyte.

Zirconium oxide-based materials supported on carbon nanomaterials have shown excellent performance electrocatalysts due to their outstanding catalytic activities and high stability. In this work, a one-pot hydrothermal method was used to prepare porous stabilized zirconia nanoparticles with yttria and ceria (YSZ and CSZ) anchored on carbon nanosheets derived from molasses fiber waste as a sustainable source and annealing at various temperatures (MCNSs). The prepared composites YSZ/MCNSs and CSZ/MCNSs exhibit superior oxygen evolution reaction performance in alkaline medium. Various physicochemical analysis techniques such as SEM, EDX, HR-TEM, BET, XRD and XPS are employed to characterize the designed catalysts. The results showed that the doping of molasses fibers exfoliated into 2D nanosheets controlled the growth of the YSZ particles into the nanosize and increased their crystallinity. This improves the electrochemical surface area and stability, and modulates the electronic structure of zirconium, yttrium and cerium which facilitate the adsorption of OH − ions, and all contribute to the higher catalytic activity.

Furthermore, it is the first reported method to determine the paracetamol in presence of its toxic impurities (i.e., p-aminophenol and p-chloroacetanilide) simultaneously. Square wave (SWV) and cyclic voltammetric (CV) techniques were used to investigate the effect of scan rate, concentration, and pH in order to optimize sensor’s response. The calibration curves were obtained in both low and wide concentration ranges from (0.1–200 nM) to (3.0–100.0 µM) for both drugs with limit of detection (LOD) as low as 28 and 29 pM and limit of quantification (LOQ) 93 and 97 pM for PAR and MCP, respectively. The proposed sensor was used to assess PAR, MCP, and paracetamol toxic impurities in human plasma, urine samples, and pharmaceutical formulations with satisfactory results showing a broad dynamic linear range from 100 pM to 100 µM with high sensitivity and good reproducibility.
