This paper deals with the development of a liquid measuring instrumentation using the popular tetrapolar electrode configuration. The system consists of four-electrode ring shape using Cromium metal plate and a small measurement. The developed instrument is calibrated with the help of prepared saline solution prepared in lab. A liquid of known parameter is placed inside the measurement cell and...

In this paper, results of Particle Image Velocimetry (PIV) measurements of the electrohydrodynamic (EHD) flow velocity fields in an electrostatic precipitator (ESP) are presented. The measurements were carried out for various densities of submicron dust. The ESP was an acrylic parallelepiped with a wire discharge electrode and two plate collecting electrodes. The positive DC voltage was applied...

in this study, removal of methylene blue by electro-coagulation method using aluminum and iron electrodes was investigated. the influence of the operating parameters such as contact time, current density, anode type, inter-electrodes distance, initial and final ph and energy consumption rate was determined. dye removal was increased with increases in solution ph, current density and contact tim...

Feasibility Study of Shaped Electrode The objective of this project was a feasibility study of a novel, large-area plasma reactor for thin film production, based on a shaped electrode technique (“lens”) to compensate the standing wave non-uniformity. Cylindrical Test Reactor In the first phase a cylindrical reactor was designed and constructed to show the “proof of principle” of a novel electro...

Effects of diffusion induced stress on the hydrogen absorption into plate form electrodes of b-phase PdHx are discussed numerically based on the Volmer–Tafel route of the hydrogen evolution reaction, and thermodynamic considerations involving stress fields and non-ideal interactions of hydrogen in the electrode. It is found that the self-induced stresses enhance the absorption rate and may exce...

A novel liquid crystal (LC) wavefront corrector with smooth modal influence functions is proposed and realized. The device consists of a thin layer of planar aligned nematic LC sandwiched between a glass plate with a conductive electrode and a plate made of ceramic material with a very high dielectric constant. Control electrodes are positioned on the back side of the ceramic plate, opposite to...

Effect of configuration (structure of electrode, interelectrode gap, positions of inlet and outlet, volume of the cell and additional nets) on mass transfer characteristic of a filter-press type electrochemical cell has been studied. The mass transfer coefficients on the electrodes were obtained by using the well-known technique based on the determination of limiting diffusion current. It is fo...

The hydrogen clearance method for measuring local tissue blood flow was adapted for use in the brain of the unanesthetized rat by means of a stainless steel plate screw mounted in the skull as the reference electrode instead of a calomel electrode. Blood flow was measured at 3 sites in the brains of 5 threemonth-old rats over a 6-week period. Blood flow in the frontal cortex and the cerebellum ...
