Electrochemical determination of salbutamol in aqueous solutions with UiO-66/rGO-modified electrodes
The synthesis of the UiO-66/rGO material involved combining UiO-66 with reduced graphene oxide (rGO). This resulting composite found application in the electrochemical determination of salbutamol (SAL) through modification of a glassy-carbon electrode (GCE) with UiO-66/rGO. Differential pulse voltammetry served as the chosen technique, offering a wide linear range spanning 1–160 μM and demonstrating a low limit of detection at 0.84 μM

In the present study, we have made an attempt to prepare complexed PVA-PVP-KNO3-BaTiO3 blend composite polymer electrolyte membranes composed of potassium nitrate (KNO3) as salt and BaTiO3 of various concentrations as filler and studied their properties. The advantages of addition the fillers are the increase in ionic conductivity at room temperatures and the improvement of the stability at the interface with electrodes.

Ebook "Consequences of combinatorial studies of positive electrodes for li-ion batteries" help resolve a number of points of confusion and contradiction in the literature. Amongst other important findings, the compositions and synthesis conditions giving rise to layered-layered nano-composites are presented and electrochemical results are used to show how better electrode materials can be achieved by making samples in the single phase-layered regions.

This paper presents a methodology for studying nucleation and growth mechanisms of metals onto a glassy carbon electrode in a deep eutectic solvent (DES), a mixture of choline chloride and urea at a molar ratio of 1:2. Characteristics and composition of Co(II) complexes formed with the DES were evaluated by means of UV-vis measurements, which confirmed the good stability of these species at room temperature.

In particular, those materials present the highest amount of meso (3–10 nm) and larger meso-macropores and the highest content of fluorine in their composition. Then, fluorine-doped silicon oxycarbide derived materials can be potentially used as electrodes for supercapacitors in the field of energy storage applications.

Adsorptive cathodic stripping voltammetric determination of aluminum at ng mL −1 levels in salt samples based on the metal complexation with Calcon (1-(2-hydroxynaphthylazo)-2 naphthol-4-sulfonic acid) and the subsequent adsorptive deposition onto a hanging mercury drop electrode was studied. Central composite design was used as a design method. Several chemical and instrumental parameters (pH, ligand concentration, deposition time, deposition potential, and complexing time) were involved in the experimental design.

Thiolated chitosan (CS–TGA) was prepared using chitosan (CS) and thioglycolic acid (TGA). Then MWCNTs were added to the mixture of CS–TGA and CS to prepare the CS/CS–TGA/MWCNs porous composite by freeze-drying method and this composite was used to modify an indium tin oxide glass electrode. The electrode was used as a sensor for Pb2+. The morphology and structure of the composite were characterized by infrared spectroscopy and scanning electron microscope, and their electrochemical behavior was also studied.

Single-walled carbon nanotube (CNT) and chitosan composite (chitosan*CNT) based sensors were developed as DNA biosensors, and then they were applied for electrochemical investigation of the interaction between the anticancer drug mitomycin C (MC) and DNA. The oxidation signals of MC and guanine were monitored before and after the interaction process by differential pulse voltammetry (DPV). The DPV results were in good agreement with those of electrochemical impedance spectroscopy (EIS).

The developed bioanode electrodes were obtained by modification of composite GCPEs with glucose oxidase (GOx) and different nanomaterials like manganese(IV) oxide nanoparticle (MnO2 np) and aluminum titanate (Al2O3–TiO2) bimetallic nanostructure. These nanostructures were utilized in a GCPEbased enzymatic bioanode construction for the first time.
