In this paper we designed and prepared three free-metal organic days Dye 1, Dye 2 and Dye 3 based on indoline with n-phenly substituents iminodibenzyl as the electron donor group. We used cyanoacrylic acid substituent as the electron acceptor anchoring group in organic dyes. The proposed dyes were prepared from iminodibenzyl as the starting material by standard reactions and characterized by di...

Background and Aim: In this study, the removal of dye blue reactive-171 by combination of advanced oxidation processes UV/H2O2 and SBAR has been investigated. Methods: The efficiency of chemical and biological system was first investigated separately. In chemical system, the kind, power, initial dye concentration and hydrogen parasitize and in biological system, hydraulic detention time, aerati...

as dyes are the most important pollutants of many industrial wastewaters. a large amount of reactive black 5 enters the environment in iran because of the use of this dye in iran's textile industries, so the goal of this study was to survey the catalytic ozonation process with bone char in removal of reactive black 5 dye from synthetic wastewater. in this experimental study bone char (bc) was p...

natural dye extract of walnut shell, was extracted using an ultrasonic processor and purified by hot saponification method, has been studied as a novel sensitizing dye to fabricate tio2 nanoparticles based dye sensitized solar cells (dssc). the extract was characterized using uv–vis absorption spectroscopy and fourier transform infrared (ftir) employed to identify the anchoring groups in walnut...

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...

A major deficit in suitable dyes is stifling progress in the dye-sensitised solar cell (DSC) industry. Materials discovery strategies have afforded numerous new dyes; yet, corresponding solution-based DSC device performance has little improved upon 11% efficiency, achieved using the N719 dye over two decades ago. Research on these dyes has nevertheless revealed relationships between the molecul...

دست یابی به سیل ایده آل در ترمیم های کامپوزیتی یکی از مهمترین اهداف دندانپزشکی ترمیمی در سالهای اخیر بوده است. بررسی نفوذ رنگ رایج ترین شیوه مطالعه ریز نشت است. این روش از ارزیابی سه بعدی حساسیت کمتری دارد. به دلیل فقدان مطالعات ارزیابی ریزنشت کامپوزیت ها به روشfluid filtration در دندان های شیری، در این تحقیق بر آن شدیم تا میزان ریزنشت باندینگهایself etch و total etchرا در دندان های شیری به روش...

Background: Dyes have complicated structure, are usually toxic and resistant to biological treatment which entere into environment by industrial waste streams. The aim of this study was the removal of reactive red 198 dye (RR 198) by photolysis (UV) and photocatalytical (TiO2/UVC) processes. This study was conducted to investigate the effects of dye concentration, pH, TiO2 dose, and contact tim...
