In this work we present data about electronic devices based on a planar structure; inert electrode/nanophase chalcogenide glass/inert electrode in close proximity with a source of silver (Ag) oriented laterally over the chalcogenide glass film. The conductivity of the devices changes with radiation and it can be measured by contacting the two inert electrodes. Spacing of the electrodes was chos...

Atmospheric pressure microplasma jet sources driven by radio-frequency wave of 13.56MHz and by low frequency continuous wave of several kHz ac were fabricated and characterized. The source consists of an ac-driven copper wire (needle) surrounded by dielectric layer that are placed in a glass tube, and a ground plane electrode (pin-to-plane electrode configuration). The basic physical and chemic...

We fabricated a miniaturized electrochemical uric acid biosensor with a 3-aminopropyltriethoxysilane (APTES)-modified indium tin oxide (ITO) microelectrode array (μEA). The ITO-μEA on a glass plate was immobilized with the enzyme uricase, through a cross-linker, bis[sulfosuccinimidyl]suberate (BS3). The enzyme-immobilized electrode (uricase/BS3/APTES/ITO-μEA/glass) was characterized by atomic f...

We synthesized platelet graphitic-nanofibres (GNFs) directly onto FTO glass and applied this forest of platelet GNFs as a highly porous structural counter-electrode in dye-sensitized solar cells (DSSCs). We investigated the electrochemical properties of counter-electrodes made from the highly porous structural GNFs and the photoconversion performance of the cells made with these electrodes.

This paper reports a rapid microchip-based electrochemical enzyme immunoassay with surface-functionalized poly(dimethylsiloxane) (PDMS) channel. The microchip fabricated on a glass substrate by photolithography consists of a three-electrode system for electrochemical detection and is assembled with the antibody-immobilized PDMS channel by plasma treatment. For effective immobilization of target...

Separators are needed in microbial fuel cells (MFCs) to reduce electrode spacing and preventing electrode short circuiting. The use of nylon and glass fiber filter separators in single-chamber, aircathode MFCs was examined for their effect on performance. Larger pore nylon mesh were used that had regular mesh weaves with pores ranging from 10 to 160 mm, while smaller pore-size nylon filters (0....

The respirometer is shown in Fig. 1. The cathode was made from gold wire of 0.51 mm diam which was coated with glass of low melting point (4). After mounting the cathode as shown in Fig. 1, the gold and its glass coating were ground to a flat surface and polished using a series of carborundum grinding powders. The cathode was maintained at -0.45 V with respect to the calomel electrode. The elec...

We report on the use of polyelectrolyte multilayer (PEM) coatings as a non-biological surface preparation to facilitate uniform cell attachment and growth on patterned thin-film gold (Au) electrodes on glass for impedance-based measurements. Extracellular matrix (ECM) proteins are commonly utilized as cell adhesion promoters for electrodes; however, they exhibit degradation over time, thereby i...

The miniaturization of cation sensitive glass electrodes (Eisenman, 1962) is part of a programme designed to monitor continuously the plasma cationic concentrations in human extracorporeal circulations and in the physiologically normal animal. The investigation of diurnal and metabolic changes in plasma cationic parameters using flame photometry on samples from animals submitted to open operati...

The authors report the growth of multiwall carbon nanotubes directly onto indium tin oxide glass via chemical vapor deposition as large area semitransparent electrodes for organic solar cell applications. The rate of nanotube growth on this ternary oxide is greatly reduced as compared to that of silicon dioxide and glass substrates enabling a high degree of control over nanotube height. The str...
