in the present work, an efficient modified carbon-ceramic electrode by multi-walled carbon nanotubes/ionic liquid nanocomposite (mwcnts/il/cce) was prepared through a simple and repeatable procedure. the introduced modified electrode was used for the study of the electrochemical behaviour and determination of tryptophan (trp) in the presence of uric acid (ua) using cyclic voltammetry (cv), diff...

Anodic oxidation is used to evaluate the effects of pure titanium in a sulphuric acid electrolyte in order to evaluate the relationship between the Ti02 anatase crystalline phase formation and anodization parameters. Multiple characterisation techniques were used and found that the thickness showed significant increase in TiOz at 70V, FESEM observed significant porosity at the arcing voltage co...

A thin industrial corrosion-protection nanostructured coating for the Al alloy AA2024-T3 is demonstrated. The prepared in a two-step process utilizing hard anodizing as pre-treatment, followed by sealing and atomic layer deposition (ALD). In first step, sulfuric acid at low temperature converts surface into low-porosity anodic oxide. second pores are sealed coated low-temperature ALD using diff...

A comparative study of benzene oxidation at boron-doped diamond (BDD) and nitrogenated nanocrystalline diamond (NCD) anodes in 0.5 M K(2)SO(4) aqueous solution is conducted by using cyclic voltammetry and electrochemical impedance spectroscopy. It is shown by measurements of differential capacitance and anodic current that during the benzene oxidation at the BDD electrode, adsorption of a react...

We herein report that the regioselective anodic fluorination of S-alkyl benzothioate and its derivatives in various aprotic solvents using Et3N·nHF (n = 3-5) and Et4NF·nHF (n = 3-5) as supporting electrolyte and a fluorine source successfully provided the corresponding α-fluorinated products in moderate yields. Dichloromethane containing Et4NF·4HF was found to be the most suitable combination a...

Anodic porous alumina with duplex layers exhibits a voltage-induced switching effect and is a promising candidate for resistive random access memory. The nanostructural analysis of porous alumina is important for understanding the switching effect. We investigated the difference between the two layers of an anodic porous alumina film using transmission electron microscopy and electron energy-lo...

This paper outlines a single photon sensitive detector array. The detector structure is made via CMOS compatible wafer-scale post-processing. The total system comprises a CMOS imaging chip with charge sensitive pixels, an electron multiplier and a photo-cathode. The electron multiplication is achieved by operating a thick layer of integrated porous anodic alumina as an MCP. Material and geometr...

An immuoelectrophoretogram of catalase in peripheral blood leukocytes showed a distinctive pattern in patients with inflammatory leukocytosis in contrast to that in patients with myelogenous leukemia. An abnormal catalase-related antigen, a, with anodic migration, coexisted with a normal cathodic or ßantigen in the peripheral blood leukocytes of patients with inflammatory diseases. Leukocytes ...

5.1 Anodic Aluminum Oxide (AAO) Templated Nanowires Due to their small sizes and potential for controllable features, nanowires/tubes represent an attractive option for increasing the surface area of ceria-based anodes. Templated approaches are currently the most flexible routes to fabricating nanowires/tubes, as only a suitable filling method needs be developed for a particular material compos...

This paper presents the development of low cost Nano membrane fabrication system. The system is specially designed for anodic aluminum oxide membrane. This system is capable to perform the processes such as anodization and electro-polishing. The designed machine was successfully tested for ‘mild anodization’ (MA) for 48 hours and ‘hard anodization’ (HA) for 3 hours at constant 0C. The system is...
