The dipotassium salts of maleic, fumaric and acetylenedicarboxylic acids were electrooxidized and the reaction products were analyzed qualitatively and quantitatively by UV/VIS and FT-IR spectroscopy. Acetylene, carbon dioxide and carbon monoxide, along with polyynes, are the products obtained from maleic and fumaric acids. The best acetylene yields are obtained from fumaric acid and not from m...

In order to further enhance the Ni/Ce 0.8Gd0.2O2-δ (Ni/GDC20) cermet anodic performance for low temperature solid oxide fuel cell (LT-SOFC), a study was conducted on the nanostructuring of NiO/GDC composite by only once wet-infiltration of rhodium chloride precursor. By using electrochemical impedance spectroscopy (EIS) analysis, the effect of only one drop of Rh-infiltrating solution on ...

a multi-walled carbon nanotube modified paste electrode (mwcn-pe) was used for determination of promethazine (pmz) in drug formulations and blood plasma by cyclic voltammetry (cv) and differential pulse voltammetry (dpv) methods. results revealed that the mwcn-pe shows an electrocatalytic activity toward the anodic oxidation of pmz by a marked enhancement in the current response in buffered sol...

A novel electrode modified with silver nanoparticles was fabricated. It is found that the reducibility of silver nanoparticles is higher than for bulk silver by comparing a silver nanoparticles modified electrode with a silver micro-disk electrode. When SCN was added, a new oxidation peak occurred and the anodic peak current of silver nanoparticles decreased. The new anodic peak current is prop...

We demonstrate a new fabrication process for hybrid semiconductor-superconductor heterostructures based on anodic oxidation (AO), allowing controlled thinning of epitaxial Al films. Structural and transport studies oxidized films grown insulating GaAs substrates reveal spatial non-uniformity enhanced critical temperature magnetic fields. Oxidation InAs with conducting quantum well show similarl...
