The objective of the presented research was to examine the potential of capillary electrophoresis (CE) for the analysis of structurally different reactive dyestuffs, their activation and posterior hydrolysis, with special focus on optimization of the working conditions. Preliminary, the effect of various additives to the background electrolyte on the resolution improvements versus migration tim...

In this paper, the comparative studies of dye sensitized solar cells (DSSC) manufactured with different cathode materials have been investigated. It has been observed that different cathode materials have different bandgap energies and it directly affect the efficiency of DSSC. The tested materials for counter electrode are carbon black and graphite. Although both of these materials are carbon ...

We describe the pre-staining of proteins in normal human serum with Remazol Brilliant Blue before separation by disc electrophoresis. Critical to reproducibility are: dye concentration of 0.16 mol/L in a Tris-glycine buffer (pH 8.3), use of equal volumes of serum and dye solution, a tagging period of 2 h at room temperature, and electrophoresis of 0.1 mL of the mixture at 2.5 mA/gel for about 2...

The removal of Reactive Black 5 dye in an aqueous solution by electrocoagulation (EC) as well as addition of flocculant was investigated. The effect of operational parameters, i.e. current density, treatment time, solution conductivity and polymer dosage, was investigated. Two models, namely the artificial neural network (ANN) and the response surface method (RSM), were used to model the effect...

the used activated carbon was derived from pine-cone and was used for the removal of acid black 1(ab1) and acid blue 113(ab113) dyes. a batch sorption study was carried out in order to obtain optimum isotherm model. the study showed the best fit of the adsorption isotherm data was obtained using the langmuir model for both dyes. the monolayer maximum saturation capacities of ab1 and ab113 dyes ...

Colored waterborne polyurethanes have been widely used in paintings, leathers, textiles, and coatings. Here, a series of black waterborne polyurethanes (WPUs) with different ratios of black dye, Sudan Black B (SDB), were prepared by step-growth polymerization. WPU emulsions as obtained exhibit low particle sizes and remarkable storage stability at the same time. At different dye loadings, essen...
