In this study, we present the methods of the particle separation by employing electrokinetic phenomena (dielectrophoresis (DEP) and traveling-wave electroosmosis (TWEO)) and the inclined gravity. The methods can separate particles of same sign DEP. However, it is very difficult to separate particles on a plane electrode. To cope with this problem, we create the “Bottle neck Fork-trace electrode...

In this paper we studied preparation of working films of dye-sensitized solar cells using screen printed method. The organic dye based on phenoltiazine with cyanoacrylic acid as the electron donor group utilized as photosensitizer. Fluorine-doped thin oxide FTO coated glass is transparent electrically conductive and ideal for use in dye-sensitized solar cells. FTO glass was coated by screen pri...

The use of postural restriction in the treatment of patients with hiatus hernia has been analysed using continuous oesophageal pH measurements. It appears that it is not effective in the prevention of reflux of acid. The percentage of the time during which oesophageal pH remains below 5 is not significantly different when comparison is made during periods of sitting and lying. The frequency of ...

The results 1 from measurements made with the glass electrode and spectrophotometer show that brilliant cresyl blue penetrates as free base into the vacuoles of living cells of Nitella. The present paper describes similar experiments with azure B, methylene blue, and crystal violet. Since the methods for the condition of cells, extraction of the sap, penetration experiments, extraction of free ...

We demonstrate a tunable focus liquid crystal (LC) lens by sandwiching a homogeneous LC layer between a planar electrode and a curved electrode. The curved electrode which is made of conductive polymer has parabolic shape with a large apex distance. Such design dramatically reduces the phase loss which leads to a short focal length (~15 cm). By using a thin top glass substrate on the curved ele...

the electrocatalysis of the oxygen reduction reaction (orr) on carbon supportedpt-v (1:1) catalyst in polymer electrolyte fuel cells (pefc) was investigated. atan oxygen pressure of one atm an enhanced electrocatalytic property of pt-v/ccompared with pt/c is revealed. these results indicate the occurrence of adifferent electrocatalytic mechanism for the orr on pt/c and pt-v/c. anincrease of mas...

Microbial electrolysis cell (MEC) is a gripping bio-electrochemical device producing H2 gas from renewable biomass while at the same time treat wastewater.  Through extensive global research efforts in the latest decade, the performance of MECs, including energy efficiency, hydrogen production rate (HPR), and hydrogen recovery have achieved significant breakthroughs. However, employi...
