cyclic voltammogram and differential pulse polarograph of octaethyl porphyrin iron(iii) chloride in dichloromethane was investigated in the presence of pyridine, imidazole and collidine. values of e1/2 for feiii/feii redox reaction were monitored as a function of axial group concentration, and on the basis of these data, an overall oxidation-reduction and ligand addition scheme was formulated. ...

Herein, the electrolysis process, where anodic oxidation of carboxylic acids leads to decarboxylation, has been discussed synthesize organic molecules.

Electrochemical reduction of CO2 into carbon-based products using excess clean electricity is a compelling method for producing sustainable fuels while lowering CO2 emissions. Previous electrolytic CO2 reduction studies all involve dioxygen production at the anode, yet this anodic reaction requires a large overpotential and yields a product bearing no economic value. We report here that the cat...

Atomic force microscope (AFM) based local anodic oxidation of metallic and semiconducting layers has emerged as a powerful tool for nanoscale fabrication. A unique nanoscale patterning technique has been created that couples computer aided design (CAD) with the lithographic capabilities of the AFM. Target nanostructures to be deposited on a silicon substrate are rendered as a three-dimensional ...

A triboelectric nanogenerator composed of gold nanoflowers is demonstrated. The proposed triboelectric nanogenerator creates electricity by contact-separation-based electrification between an anodic metal and a cathodic polymer. For the improvement of output power via the enlargement of the effective surface area in the anodic metal, gold nanoflowers that produce a hierarchical morphology at a ...

Data on the study of kinetics and mechanism copper electro-oxidation -reduction processes in alkaline neutral solutions were obtained this work. Patterns electrochemical oxidation using alternating current established. Based data polarisation measurements kinetic parameters calculated: heterogeneous rate constant, effective activation energy electro-oxidation, which allow to establish course me...

The electrooxidation of a,c~'-coupled thiophene oligomers alkyl-protected toward anodic coupling at the terminal c~ positions was studied in solid state at room temperature. Reversible oxidation goes from a single one-electron step oxidation for the tetramers to two separate oneelectron steps for the pentamer and hexamer. The oxidation potentials are found to be primarily dependent on the conju...

We report on the micromachining of silicon microlens structures by use of scanning-probe gray-scale anodic oxidation along with dry anisotropic etching. Convex, concave, and arbitrarily shaped silicon microlenses with diameters as small as 2 microm are demonstrated. We also confirm the high fidelity of pattern transfer between the probe-induced oxides and the etched silicon microlens structures...
