Through introducing an energy antenna system into a simple phenoxazine dye (TH301), a novel and efficient dye TH305 was designed and synthesized for application in a dye sensitized solar cell with prominent overall conversion efficiency of 7.7%.
Background and Objectives: Synthetic dyes are an important group of additivesused in food products, and because of health concerns about consuming population, the application of these compounds is needed to be enough controlled. The aim of this study was to investigate the types and frequencies of the dyes used in making pastries in the confectionery of Tuyserkan city. Materials and Methods: I...
Introduction:The textile industry produces a colored effluent with different characteristics that needs to be treated. Adsorption is one of the methods for removing dyes. The aim of this study was to evaluate application of bone char as natural adsorbent for removal of acid orange 7 from synthetic textile wastewater. Methods:In this study, the effect of variations such as contact time, pH, in...
Background and purpose: In Electro/Fe2+/persulfate process, persulfate radicals are produced as powerful oxidizing agents which increase the efficiency of this process. The aim of this study was to investigate the efficiency removal of COD, TSS and dye from industrial effluent in Buali industrial area in Hamedan. Materials and methods: In this study, the batch experiment was performed using a ...
Backgrounds and Objectives: A great part of organic compounds cause more pollution in natural waters meet, are chemical dye material. Azo dyes have more usage in different industries. Azo dyes not only give undesirable dye to the water but also have mutation potential and carcinogenesis effects in human and cause the production of toxic substances in water environments.The purpose of this stud...
OBJECTIVE The aim of this study was to evaluate in vitro the effect of photodynamic therapy (PDT) using LASER or light emitting diode (LED) on cariogenic bacteria (Streptococcus mutans [SM] and Lactobacillus casei [LC]) in bovine dentin. MATERIALS AND METHODS Twenty five fragments of dentin were contaminated with SM and LC strands and divided into five experimental groups according to the the...
