Summary: A microwave-assisted in-situ polymerization method is used to coat carbon nanotubes (CNTs) with polystyrene, enabling the tuning of DC electrical conductivity and impedance characteristics in nanocomposites. The nanocomposites are characterized and confirmed to have a polystyrene layer on the surface of CNTs. The study reveals that increasing the irradiation time reduces the DC electrical conductivity and dielectric permittivity but increases the real and imaginary impedance, offering a potential method for achieving specific resistance in practical applications.

Summary: In this study, the improvement in surface inertness of carbon-nanotube (CNT) surfaces treated with oxygen plasma was analyzed using electrochemical impedance spectroscopy (EIS). CNTs are highly desirable nanomaterials due to their exceptional properties, but the chemical inactivity of CNT surfaces limits their application in bioanalytical field. Consequently, we present a comprehensive analysis of the electrochemical properties of CNTs treated under various plasma conditions.

Summary: PPy.SDS-coated carbon fiber electrodes demonstrated enhanced drug sensing capabilities compared to bare carbon fibers, with a 14-fold increase in electrochemical surface area. The use of a large counter anion as dopant, such as dodecyl sulfate, resulted in a greater drug sensing response. Differential pulse voltammetry (DPV) with PPy.SDS fiber electrodes was able to detect paracetamol with a detection limit of 34 μM and a linear response range of 50-500 μM, even in the presence of interferents like dopamine and ascorbic acid at 100 μM concentrations. This indicates the potential for real-world applications of PPy.SDS electrodes in drug sensing, with the ability to detect anti-psychotic medication like clozapine at low concentrations.

Summary: This study investigates the effectiveness of electrochemical and biological wastewater treatment for artificially prepared industrial wastewater containing important dyes. Lemna minor is used as a bioindicator to assess the environmental impact. The results show that electrooxidation treatment with iron and copper electrodes led to the highest phytotoxicity, while treatment with graphite electrodes showed no toxicity. The removal efficiency of the dye components reached 98% and over 99% after electrochemical and biological treatment, respectively. This suggests that the methods studied may serve as suitable replacements or additions to conventional wastewater treatment methods.

Summary: This study investigates the influence of surface-adsorbed resorcinol and its oxidation/reduction derivatives on the kinetics of hydrogen deposition, hydrogen evolution reaction, and oxygen evolution reaction at a polycrystalline Pt electrode in 0.1 M NaOH electrolyte by using ac. impedance spectroscopy and cyclic voltammetry. The results show that Pt-electrosorbed resorcinol molecules have a positive effect on the kinetics of hydrogen deposition. However, surface-adsorbed resorcinol species or its electro-oxidation intermediates have a detrimental effect on the kinetics of oxygen evolution reaction, while the effect on cathodic hydrogen evolution reaction is barely noticeable. These conclusions are drawn through evaluation of ac. impedance-associated parameters and cyclic voltammetry profiles in RC-free and resorcinol-modified NaOH electrolytes.
