Phenolic resin-derived activated carbon (AC) cloths are used as electrodes for large scale electric double-layer capacitors (EDLCs) or supercapacitors. To increase the energy and power density of the supercapacitor, the contact resistance between the carbon cloth and the aluminum foil current collector is reduced by modifying the Al current collectors. Different modified Al current collectors, ...

Having sufficient and accurate understanding about kinetics of phenomena, could be an important reason for further technological progresses. Finding a white-box mathematical model for weight vs. time curves of Electrophoretic Deposition (EPD) using large and small signal analysis has been studied thoroughly in the present investigation. Weight-Time curves of nano-Mullite suspension have been tr...

The preparation of La0.4Sr0.6TiO3 (LSTO) buffer layer and YBa2Cu3O7−δ (YBCO) superconducting thick film by a low cost technology was studied. The crystal orientation of LSTO and YBCO films was detected by X-ray diffraction, the conductivity of LSTO film and superconductivity of YBCO coating were investigated by standard four-probe method. Excellent in-plane alignment, smooth and dense LSTO buff...

Despite the significant advantages of capillary isoelectric focusing over gel isoelectric focusing, widespread acceptance of the technique as a replacement for gel isoelectric focusing has not occurred. Several factors contribute to capillary isoelectric focusing’s slower-than-expected adoption; perhaps the most important are the performance and procedural difficulties introduced when capillary...

Mastitis is one of the most important diseases of dairy cattle in the world. The identification and characterization of the constituent proteins in milk can be useful for studying the biochemistry and pathogenesis of mastitis. In this study, the electrophoretic patterns of milk from 10 healthy and 30 mastitic cows were studied. All of the latter milk samples were California Mastitis Test (CMT) ...

Bipolar electrode (BPE) focusing is a developing technique for enrichment and separation of charged analytes in a microfluidic channel. The technique employs a bipolar electrode that initiates faradaic processes that subsequently lead to formation of an ion depletion zone. The electric field gradient resulting from this depletion zone focuses ions on the basis of their individual electrophoreti...

The electroosmotic flow (EOF) in a poly(dimethylsiloxane) (PDMS) separation channel can be altered and controlled by adding a carboxylic acid to the prepolymer prior to curing. When the prepolymer is doped with 0.5 wt % undecylenic acid (UDA), the electroosmotic mobility in a modified PDMS channel rises to (7.6 +/- 0.2) x 10(-4) cm(2) V(-1) s(-1) (in HEPES buffer at pH 8.5), which is nearly twi...
