A Route to Surface-bound Metalloporphyrins as Models for Oxygen Reduction Catalysts [PDF]
, 2017 The attachment nonmetal and magnesium ethynyl terminated porphyrin (TEPP and MgTEPP) to glassy carbon electrode was achieved through voltammetry. These attached porphyrins were studied by cyclic voltammetry (CV) and UV-visible spectroscopy. Surface-bound

Impact of Oxygen Plasma Pre‐Treatment on Thermal Oxidation and Reliability of SiO2 on 4H‐SiC
Advanced Materials Interfaces, EarlyView.We investigate how oxygen plasma pre‐treatment affects the thermal oxidation of silicon carbide. While plasma modification increases growth rates by 84%, it reduces dielectric breakdown strength by 18%. Our findings reveal that although plasma improves the interface state density, it introduces structural damage, highlighting a critical trade‐off ...

Voltammetric Assay of Metformin Hydrochloride Using Pyrogallol Modified Carbon Paste Electrode
Acta Chimica Slovenica, 2015 The electrooxidative behavior and determination of metformin hydrochloride, anti-hyperglycemic drug, on a pyrogallol modified carbon paste electrode were investigated using cyclic voltammetry and differential pulse voltammetry. Metformin hydrochloride shows an irreversible oxidation behavior over a wide interval of pH (Britton-Robinson buffers, pH 2-9).

NiO/CNTs Nanocomposite Modified Ionic Liquid Carbon Paste Electrode as a Voltammetric Sensor for Determination of Quercetin [PDF]
A high sensitive carbon paste electrode modified with NiO/CNTs and ionic liquid (ILs/NiO/CNT/CPE) was describe for voltammetric determination of quercetin. Compared to unmodified carbon paste electrode, the electrochemical response was greatly improved

Advanced Materials Technologies, EarlyView.Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.
