The nature of an interfacial structure buried within a device assembly is often critical to its function. For example, the dye/TiO2 that comprises working electrode dye-sensitized solar cell (DSC) governs photovoltaic output. These structures have been determined outside DSC device, using ex situ characterization methods; yet, they really should be probed while held since are modulated by envir...

decolorization of remazol brilliant blue r (rbbr) by trametessp. pellets was studied in a batch reactor. dye removal process was performed in shaken flasks which contained 100 ml of rbbr aqueous solution and fungal pellets. the process was followed for 48 h and the dye removal was analyzed at a visible spectrum of 590 nm. response surface methodology (rsm) employing box behnken design at three ...

BACKGROUND Several studies have reported positive results of nonablative laser treatment of xanthelasma palpebrarum, but the published evidence is weak and inconclusive. OBJECTIVE To systematically evaluate the effect of pulsed dye laser (PDL) treatment of xanthelasmas. MATERIALS AND METHODS Twenty female Caucasian patients with 38 lesions (< or =1 mm above skin level) were enrolled. They r...

background: the purpose of the present study was to assess the efficiency of ultrasound/hydrogen peroxide processes and ultrasound/hydrogen peroxide/zno nanoparticles in the removal of blue cat 41 dye from aqueous solutions. methods: zno nanoparticles were prepared using the hydrothermal method. variables including ph, concentration of zno nanoparticles, initial dye concentration, concentration...

sawdust which is the main waste from wood industry has been used as a raw material forremoval of brilliant cresyl blue toxic dye. the effects of various parameters such as ph,electrolyte concentration, adsorbent dose, contact time and agitation rate were studied for theremoval of the dye in a concentration of 50 mg l-1. the optimum condition for the studiedparameters was applied for various con...

Background & Aims of the Study: Dyes are one of the widespread chemicals which may have many adverse effects on life cycle. Thus, this study was conducted to survey the RB19 dye removal efficacy from aqueous solution, using the SiO2 nanoparticles. Materials and Methods: This study was an experimental-lab study. The batch adsorption system were utilized to evaluated the RB...

Dye-containing wastewater generated from textile industries is a major source of environmental pollution. Azo dyes, which are the largest group of coloring agents, are widely used in industries.This research investigated the photocatalytic decolorization and degradation of an azo dye Reactive Red 198 (RR198) in aqueous solution with TiO2-P25 (Degussa) as photocatalyst in slurry form using UV li...

PURPOSE Cell replacement has the potential to be applied as a therapeutic strategy in retinal degenerative diseases such as retinitis pigmentosa and age-related macular degeneration (AMD) for which no adequate pharmacological and surgical treatments are currently available. Although controversial, the use of ciliary epithelium (CE)-derived cells is supported by evidence showing their differenti...
