Whilst hydrogen is a potentially clean fuel for energy storage and utilisation technologies, its conversion to electricity comes at a high energetic cost. This demands the use of rare and expensive precious metal electrocatalysts. Electrochemical-frustrated Lewis pairs offer a metal-free, CO tolerant pathway to the electrocatalysis of hydrogen oxidation. They function by combining the hydrogen-...

The need for miniaturized, low-cost and ultrasensitive electrochemical sensors has motivated the search and study of new nanostructured materials. We propose nanostructured indium tin oxide (ITO) electrodes as a promising platform due to their good electrical conductivity, transparency to visible wavelengths and high surface-to-volume ratio. The nanostructured electrodes were fabricated by elec...

A glassy carbon electrode modified with a molecularly imprinted polymer (MIP) containing phenacetin recognition sites is introduced. The phenacetin-selective MIP was synthesised based on the electropolymerisation of pyrrole in a 1:1 (v/v) water/ethanol with HClO4 solution. The MIP-modified electrode showed higher recognition ability in comparison with a bare electrode for procaine and aminopyri...

The presented paper studies the effect of the casting technology on the corrosion resistance of Co-Cr-Mo alloy. The investigations were conducted on a commercial alloy with the brand name ARGELOY N.P SPECIAL (Co-Cr-Mo) produced by Argen as well as the same alloy melted and cast by the lost wax casting method performed by a dental technician. The corrosion behavior of the dental alloys in an art...

This review describes recent advances in biosensors of potential clinical applications. Biosensors are becoming increasingly important and practical tools in pathogen detection, molecular diagnostics, environmental monitoring, food safety control as well as in homeland defense. Electrochemical biosensors are particularly promising toward these goals arising due to several combined advantages in...

An electrochemical P450 model compound consisting of meso-tetraphenylporphyrinatochromium(3+) chloride (CrTPP), imidazole, and acetic acid was used in acetonitrile containing alkenes. The corresponding epoxides were obtained in better yields compared to a similar electrochemical P450 model compound using meso-tetraphenylporphyrinatomanganese(3+) chloride. The results of cyclic voltammetry and c...

Carbon nanotubes (CNTs) can be effectively dispersed and functionalized by wrapping with long single-stranded DNA (ssDNA) synthesized by asymmetric PCR. The ssDNA-CNTs attached on surface of glass carbon electrode made it possible for electrochemical analysis and sensing, which was demonstrated by reduction of H2O2 on hemoglobin/ssDNA-CNTs modified electrodes. This research showed the potential...

A bifunctional molecular linker containing both aryl diazonium and trioxolane groups was synthesised and its ability to sequentially functionalise glassy carbon and covalently immobilise heme investigated. Functionalisation was demonstrated by electrochemical techniques.

High throughput electrochemical techniques are widely applied in material discovery and optimization. For many applications, the most desirable electrochemical characterization requires a three-electrode cell under potentiostat control. In high throughput screening, a material library is explored by either employing an array of such cells, or rastering a single cell over the library. To attain ...
