Summary: Montmorillonite clay, whether untreated or acid activated, efficiently adsorbs nicotine from aqueous solutions at different pH levels. Electrochemical studies show that nicotine-modified untreated clay exhibits enhanced response compared to clay without nicotine, while acid activated clay with adsorbed nicotine shows lower electrode activity. pH and clay treatment do not significantly affect the electrochemical oxidation of nicotine.

Summary: This study utilized aluminum oxide quantum dots (γ-Al2O3QDs) for concentration-based analysis of hydrogen peroxide (H2O2). The γ-Al2O3 was synthesized through a hydrothermal solution process and characterized in detail. The γ-Al2O3 QDs were employed for the detection of H2O2 and their sensing efficiency was evaluated with a three-electrode system.

Summary: Although there is still room for improvement in diagnostic and treatment options for various cancers, electrochemical biosensors using quartz tuning forks (QTF) have emerged as a promising platform. This research explores the functionalization and isolation of QTF for biomarker determination, demonstrating their unique response and sensitivity. The results show that QTF-based immunosensors have high detection sensitivity and low cost, making them ideal for point-of-care diagnostic devices.

Summary: This study investigated the electrochemical behavior of chloroaluminate species in three ionic liquids and found that EMIC-AlCl3 favored aluminum electrodeposition with lower energy consumption. The onset of aluminum deposition was determined to proceed via a threedimensional instantaneous nucleation process. The calculated diffusion coefficient values showed a correlation with temperature and the nature of the hydrocarbon group present in the ionic liquid.

Summary: Systemic sclerosis (SSc) is an autoimmune disease that affects connective tissue. A nano-engineered immunosensor surface was developed for detecting the oncostatin M receptor (sOSMR) protein in clinical samples. The biosensor showed a differential diagnostic character for limited cutaneous (lSSc) and diffuse cutaneous (dSSc) SSc subtypes. The sensing strategy demonstrated high sensitivity and potential for SSc-related biomarker research.

Summary: The in situ X-ray photoelectron spectroscopy data shows that N4111(TFSI) strongly adsorbs on the aluminum electrode within a specific potential range and undergoes electrochemical decomposition. Intensive electrochemical reduction of N4111(TFSI) occurs at lower potentials, while non-specific adsorption is observed at another potential range.

Summary: The study utilized in situ X-ray photoelectron spectroscopy (XPS), in situ mass spectroscopy, cyclic voltammetry and electrochemical impedance spectroscopy methods to explore the electrochemical behavior of a quaternary amine cation-based room-temperature ionic liquid at molybdenum carbide-derived micro-mesoporous carbon electrodes. The XPS data showed stable spectra within a wide potential range and indicated non-specific adsorption of cations and anions for analysis of catalytic reaction mechanisms. Strong adsorption was observed at certain potentials and electrochemical instability of the cation was found at more negative potentials.
