The deposition of silica on titanium dioxide surfaces
… preparations and using the technique of microelectrophoresis. Prepared silica-coated rutile samples ranging from partial to full silica coatings have been characterized using transmission electron microscopy, microelectrophoresis and nitrogen, argon and water sorption. Nitrogen and argon …

Intracellular delivery and voltage sensitivity of nanomaterials for the optical imaging of neuronal activity
… QDs as an example, has been demonstrated by microelectrophoresis technique, where electrical currents were applied to eject charged QDs through fine-tipped glass micropipettes into living cells. The amount of delivered QDs was finely controlled by tuning the ejection duration, which had a …

Electrokinetic characteristics of particulate/liquid interfaces and their importance in contamination from semiconductor process liquids
… to the semiconductor industry. The techniques of microelectrophoresis and streaming potential using flat plates and filter membranes were used to this end. The data obtained have been utilized to understand and predict particulate contamination from liquids and deposition onto the wafer surfaces. …

STUDIES ON COMPLEX FORMATION BY HEPARIN
… on the mobility of heparin were studied using microelectrophoresis. The cobaltic hexammine ion, Co(NH3)63+ seems to form a salt linkage with a disaccharide unit of heparin. Cobalt-heparin is insoluble in the usual solvents but is soluble in salt solutions of high ionic strength (0.6) and the …

Acanthamoebal surface properties and the modulation of phagocytosis
… surface carbohydrate composition. Particulate microelectrophoresis revealed a marked negative charge for both morphological forms, though less for cyst surfaces. Hydrophobicity was determined by adhesion to n-hexadecane and indicated a relatively low hydrophobic nature of both forms, though …

Metal ion removal by adsorptive bubble separation methods
… chemical interactions of flotation by using a microelectrophoresis technique. Model iron(III) and copper(II) sols were prepared by forced hydrolysis and the effect of pH, tensides and polymeric flocculants on electrophoretic mobility was determined.

Rhodium zeolites as catalysts for hydrodesulfurization reactions
… infrared spectroscopy, x-ray diffraction and microelectrophoresis were used to characterize the zeolites. Hydrodesulfurization reactions were carried out in a pulse microreactor/gas chromatograph system as a function of gas flow rate and reaction temperature. Reaction products were identified …

THE GENETICS OF ESTERASE ISOZYMES IN LETTUCE CULTIVARS.
… of the esterase isozymes was analyzed by a microelectrophoresis technique which enabled the analysis of individual seeds in the progeny from a cross involving two winter-desert cultivars of contrasting banding phenotypes. Two distinct banding patterns were observed in single seeds of these …

Cell surface analysis of the basidiomycete yeast cryptococcus neoformans
… Investigation of cellular charge by particulate microelectrophoresis revealed encapsulated yeast forms of C. neoformans manifest a distinctive negative charge regardless of the age of cells involved; in turn, the neutral charge of acapsulate yeasts confirmed that the polysaccharide capsule, and …

Kinetics of bubble-particle adhesion in flotation
… range have been determined by means of a simple microelectrophoresis technique. In general, the bubble charge is determined by the charge of the polar head of the surfactants when ionic surfactants are used to produce bubbles. However, the magnitude of the zeta-potential is reduced when the …
