• The steady flow of liquids through straight rigid tubes has been extensively analyzed, but these data cannot be applied directly to the pulsatile flow of blood through distensible, tapered and branching vascular channels. Since it is very difficult to follow flow patterns in the living animal, certain types of studies must be performed in models. Laminar flow, eddy formation and turbulence ca...

Clear native electrophoresis and blue native electrophoresis are microscale techniques for the isolation of membrane protein complexes. The Coomassie Blue G-250 dye, used in blue native electrophoresis, interferes with in-gel fluorescence detection and in-gel catalytic activity assays. This problem can be overcome by omitting the dye in clear native electrophoresis. However, clear native electr...

The aim was to assess the ability of microcosms (laboratory-scale shallow ponds) as a post polishing stage for the remediation of artificial textile wastewater comprising two commercial dyes (basic red 46 (BR46) and reactive blue 198 (RB198)) as a mixture. The objectives were to evaluate the impact of Lemna minor L. (common duckweed) on the water quality outflows; the elimination of dye mixture...

zno and tio2 nanoparticles wereimpregnated with merbromin dye and used as modified photocatalysts for degradation of phenol. dye-modified zno and tio2 showed significantly higher photocatalytic activity than neat zno and tio2 under visible light illumination. moreover, the prepared dye-modified zno showed superior photocatalytic efficiency in degradation of phenol compared to the dye-modified t...

sodium oxalate without SDS) by varying the concentration of the dye (0.03 or 0.12 mmol/L), sodium oxalate (0 or 2 mmol/L), and SDS (25 or 100 mg/L) in all combinations. For protein assays, we mixed 20 ␮L of sample, calibrator, or water (blank) with 1 mL of PRM reagent and measured the absorbance at 600 nm after 30 min against the blank. The effects of the aminoglycosides on the absorbance readi...

Recovered papers contain several chromophores, such as wood lignin and dyes. These have to be eliminated during paper recycling in order to produce white paper. Hydrogen peroxide under alkaline conditions is generally used to decolorize lignin, but its effect on dyes is limited. Copper(II)-phenanthroline (Cu-Phen) complexes can activate the oxidation of lignin by hydrogen peroxide. Hydrogen per...

Orthodontic adhesive is often left on the tooth surface when a multibracket appliance is debonded, and it is difficult to remove because its colour is similar to that of the tooth. If the adhesive changed colour during debonding, residual adhesive could be more easily removed. This in vitro study evaluated the usefulness of adhesive mixed with a small amount of fluorescent dye for clinical orth...

To reduce costs, a low-cost thin-film solar cell technique known as the Dye Sensitized Solar Cell (DSSC)/Gratzel emerged. DSSC is an easy to manufacture photovoltaic but lacks its stability and higher conversion efficiency factors. In this paper, overcome these challenges keep cost factor on trial, photogalvanic was also studied using H-shaped glass tube. Both cells were dyes Erythrosin B, Tart...

Abstract Azo dyes released by the textile industries cause severe damage to environment and living organisms. The degradation of azo is widely studied using enzymatic methods. Laccase a copper-containing enzyme that degrades into less toxic compounds. In this work, crude laccase produced alkaliphile Pseudomonas mendocina in mixed dye showed 0.386 U/mL activity at pH 8.5. A combination green syn...

New mixed-substituent amino/carboxyphenylporphyrins for a dye-sensitized TiO2 solar cell were prepared using several synthetic routes. The reaction of 4-carbomethoxyand 4-acetamidobenzaldehydes with pyrrole in propionic acid under aerobic conditions afforded mixtures of mixed amide/ester substituted tetraphenylporphyrins which were separated using centrifugal chromatography then deprotected to ...
