A method of electrophoresis utilizing cellulose acetate is described wherein quantitation of serum protein fractions by densitometry is accomplished within 2 hr. of initiation of the procedure. The densitometer was found to have a linear response to amido black dye. Albumin and y-globulin demonstrated equal dye-binding characteristics. Combined with the absence of albumin trailing, this has aff...

We have developed a new guest-host reflective display using a dye-doped dualfrequency liquid crystal (DFLC) gel. By combining dye absorption and maximal light scattering, the display is polarization independent and exhibits a high contrast ( 230:1). The high reflectivity (R 50%) is because of the vertical aligned structure at 0 Vrms. The fast response time ( 5 ms) is also fast due to the freque...

This study describes a systematic approach of TiO2/carbon black nanoparticles with respect to the loading amount in order to optimize the catalytic ability of triiodide reduction for dye-sensitized solar cells. In particular, the cell using an optimized TiO2 and carbon black electrode presents an energy conversion efficiency of 7.4% with a 5:1 ratio of a 40-nm TiO2 to carbon black. Based on the...

OBJECTIVE The aim of this in vitro study was to analyze color stability of monocrystalline and polycrystalline ceramic brackets after immersion in dye solutions. METHODS Seven ceramic brackets of four commercial brands were tested: Two monocrystalline and two polycrystalline. The brackets were immersed in four dye solutions (coffee, red wine, Coke and black tea) and in artificial saliva for t...

SBA-15 grafted with N-(4-(trimethylsilyl) butyl)-9H-fluorene-9-amine was synthesized by a simplestrategy and applied to removal of Acid Red 33 and Acid Black 194 from aqueous solutions. SBA-15 was synthesized and Functionalized according to procedure in the literature. Fluorenefunctionalized SBA-15 was showed the BET surface area 200 m2g-1 and pore diameter 4.2 nm,based on adsorption-desorption...

The presence of synthetic dyes in textile wastewater is a problematic issue for environmentalist. Nowadays, dye removal is practiced via different methods. Among all these methods, biodecolorization is an ideal technique. The present research apples vermicompost microflora to remove reactive black- C, pH = 7, and under anaerobic condition. At 36h, removal efficiencies of 94.79%, 94.06%, and 93....
