Research ArticleOpen accessEvery word in the titleEffect of Carboxyl-Functionalized Single Walled Carbon Nanotubes on the Interfacial Barrier Height of Malachite Green Dye Based Organic DeviceSudipta Sen, Nabin Baran ManikIn this study, we have estimated the interfacial barrier height (ɸb) of Indium Tin Oxide (ITO) coated glass/Malachite Green (MG) dye/Aluminium (Al) based organic device and subsequently we have also observed the effect of carboxylfunctionalized SWCNT (COOH-SWCNT) on the ɸb. Presence of COOH-SWCNT reduces the interfacial barrier height as SWCNT acts as filler and provides easy path for charge percolation. … …Physics International, Vol. 10, Issue 1 · 31 Jul 2019 · 12,391 accessesView PDFCite

Zabin, Hamzah H. Abu-SittahThe main purpose of this research was to investigate the ability of Oleander plant (Al Defla) tissues to adsorb Methylene Blue (MB) dye from polluted water. The experiments were carried out through batch-adsorption technique to investigate the influence of the following experimental parameters on adsorption process namely, adsorbent quantity, MB initial concentration, adsorbent particles size, ionic strength, pH and temperature. … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 4 Jun 2016 · 7,994 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDecolorization of Six Synthetic Dyes by FungiE. Samuel Hartikainen, Otto Miettinen, Annele Hatakka, Mika A. KähkönenTo find out ability of fourteen basidiomycetes and four ascomycetes strains to grow in the presence of synthetic colour dyes and to degrade them, fungi were cultivated on the malt agar plates containing 0.5 g kg-1 dye, either Remazol Brilliant Blue R, Remazol Brilliant Yellow GL, Remazol Brilliant Orange 3 R, Reactive Blue 4, Remazol Brilliant Red F3B or Reactive … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 31 Mar 2016 · 8,978 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLarge Scale Synthesis of ZnO Nanostructures of Different Morphologies through Solvent-free Mechanochemical Synthesis and their Application in Photocatalytic Dye DegradationRaúl Sánchez Zeferino, Jesús Alberto Ramos Ramón, Ma. Eunice de Anda Reyes et al.Well crystalline, near-stoichiometric zinc oxide nanostructures of different morphologies are fabricated in large scale, utilizing a simple, cost effective mechanochemical synthesis in absence of solvent. Effects of ionic and nonionic surfactants along with the concentration of hydrolyzing agent on the evolution of nanostructure morphology have been studied. It has been observed that while a cationic surfactant such as Cetyltrimethylammonium Bromide … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 16 Jan 2016 · 8,932 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalyze the Absorption Properties and I-V Characterization of Dye Sensitized Solar Cell Using Ruthenium DyeAnees Ur Rehman, Farooq Aslam, Haseeb Ahmad KhanIn this study, Dye Sensitized Solar Cells (DSSC) has been fabricated using natural organic dye extracted from Ruthenium Dye and its I-V characterization and absorption properties have been analyzed. It is observed that the selected natural dye absorbed all visible light and supports electrons motion across the semiconductor interface. The dye acts as sensitizer because the titanium dioxide (TiO2) cannot … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 4 · 30 Dec 2014 · 7,391 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBIOTRANSFORMATION OF TEXTILE DYES: A BIOREMEDIAL ASPECT OF MARINE ENVIRONMENTR. S. Shertate, Prakash ThoratPresence of huge amount of salts in the wastewater of textile dyeing industry is one of the major limiting factors in the development of an effective biotreatment system for the removal of dyes from textile effluents. Large number of textile industries are located on the coastal areas due to ease of transport to the various places in world and help … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 7,383 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRAPID DEGRADATION OF AZO DYES USING NANO-SCALE ZERO VALENT IRONNabila Rahman, Zainal Abedin, M. Ali HossainIn the present study, nano-scale Zero Valent Iron (NZVI) was synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for hours. A systematic characterization of NZVI was performed using XRD, SEM and … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 8 Apr 2014 · 8,599 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffectiveness of Photocatalytic Decolourization of Reactive Red 120 Dye in Textile Effluent Using UV/H2O2Rishi Ananthashankar, Abdel GhalyThe effectiveness of Advanced Oxidation Process (AOP) for degradation of reactive red 120 dye in aqueous solutions was tested in this present study. Ten different concentrations of the reactive red 120 dye were exposed to UV alone and a combination of UV with two different concentrations (10 ml/L and 20 ml/L) of H2O2 for 10 different retention times at the … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,408 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhotocatalytic Decolourization of Textile Effluent Containing Reactive Red 120 Dye With UV/TiO2Rishi Ananthashankar, Abdel GhalyThe efficiency of degradation of an aqueous solution of reactive red 120 dye using Advanced Oxidation Process (AOP) was evaluated. A low pressure UV lamp and a combination of UV/TiO2 were tested using ten different dye concentrations (50 - 500 mg/L) at several retention times (5.2-60 min) a pH of 10.5. The effect of acidic pH (pH = 3) on … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 8,353 accessesView PDFCite
