Summary: Electrochemical methods play a crucial role in neural engineering, but are currently underutilized. Research could benefit from more consistent and target-oriented electrochemical methodology and instrumentation. Standardization, consistency, and comparability will be key in translating microtechnology into biomedical and clinical applications.

Summary: Enhancing selectivity is crucial in the research of electrodes as catalysts or sensors. Nanoporous electrodes are widely used in various applications. This study proposes that surface adsorption of reactant molecules is another crucial factor in achieving selectivity. The degree of influence of the nanostructure on selectivity depends on the adsorptive capacity of the reaction.

Summary: Five new imidazolium ionic liquids were synthesized and evaluated for their efficiency in precipitating PtCl62- in HCl media. A novel mixed-ILs system showed excellent extraction efficiency for Pt(IV) from mixed metal solutions, selectively separating Pt(IV) ions from metal ions of Rh(III), Fe3+, Ni2+, Cu2+, and Zn2+. Surface characterization techniques confirmed the successful electrodeposition of metallic Pt on the cathode surfaces.

Summary: The study examined an artifact appearing as an oxidation peak overlapping the reduction peak in low-loaded Pt/C electrodes, attributed to crossover hydrogen accumulation in the working electrode. This phenomenon is expected to be observed more frequently in the future as noble metal loadings in PEMFC catalysts are forecasted to decrease.

Summary: Understanding the role of water in electrocatalysts in different electrolytes is challenging. Small amounts of water promote methanol oxidation in methanol-based electrolytes, while in acetonitrile-based systems, solvent molecules inhibit the formation of an oxide layer at the surface even with up to 1% water concentration.

Summary: This study presents a novel approach to explore the electrocatalytic characteristics of platinum electrodes for the electrocatalytic oxidation of petrol in non-aqueous solutions. The results demonstrate that metal content in Tetrabutylammonium perchlorate (TBAP) acts as a catalyst, interacting effectively with substances in petrol and forming a new electroactive product. Principal Component Analysis (PCA) can be used to differentiate different brands of petrol based on electrochemical profiles.

Summary: A novel electrochemical approach using platinum and boron-doped diamond (BDD) electrodes was employed to study the oxidative stability of the drug abacavir. The results showed that electrochemical oxidation led to faster degradation of abacavir compared to traditional chemical oxidation using hydrogen peroxide. The rate of degradation and the composition of degradation products were found to be pH-dependent.

Summary: This study investigates the mechanism, kinetics, and suitable catalysts for the hydrogen oxidation reaction (HOR) in organic media relevant to the nitrogen reduction reaction (NRR). The results suggest that a high-performance catalyst for the H2 oxidation as an anode process for the Li-mediated NRR is likely to emerge through the design of multicomponent systems, facilitating the kinetics of both HOR pathways and suppressing poisoning of the catalytic surface.

Summary: This study investigates the redox reactions of elemental sulfur under different conditions and explores the effects of different electrolytes on the performance of lithium-sulfur batteries. The results show that by optimizing the electrolyte and electrode materials, the kinetic behavior of sulfur reactions can be improved, providing a potential solution to the short service life issue of lithium-sulfur batteries.

Summary: The reduction of acetol on platinum and palladium electrodes was studied, showing that different crystallographic orientations have varied effects on the reaction. While acetol reduction on low-index platinum surfaces is hindered by CO poisoning, acetol decarbonylation still occurs on palladium monolayers. The selectivity of acetol reduction is strongly influenced by electrolyte pH and applied potential.

Summary: This research investigates the use of mixed membranes composed of conductive poly(IL)s and ionic liquids in amperometric gas sensors. The study finds that the membranes exhibit high robustness and non-flowing properties, while also showing excellent and reproducible analytical responses towards gases. The results demonstrate the potential of these membranes as designer gas sensor materials for robust sensor devices.

Summary: This study reports for the first time on the in situ transduction of ion-selective electrodes' electrochemical responses to emission change signals under non-zero-current conditions. By introducing a dispersed redox and emission active ion-to-electron transducer on a PVC-based membrane, the electrochemical trigger induces ion exchange between the membrane and solution, resulting in changes to the emission spectrum. Additionally, the proposed optical readout offers a wider linear response range compared to traditional electrical signals in voltammetric or coulometric mode.
