Research ArticleOpen accessPhrase in the titleCyclic Volta Metric Study of Alizarin Yellow R and Some Analogous Arylazo Compounds in DMF and in Aqueous MediaHossnia MohranThe Cyclic Voltammetry (CV) was used to investigate the electrochemical behavior of alizarin yellow R and some analogous arylazo compounds having almost the same central azo group. For this purpose, the substances chosen for the measurements are Alizarin Yellow R (AYR), Eriochrome Black T (EBT) and Sudan II (SUD II). The investigations were carried out at room temperature (298 K) … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 7,235 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRAPID 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 PDF Cite

Research ArticleOpen accessAll words, across the recordOptical and Structure Analysis of ZnO:Al FilmNeilo Marcos Trindade, Michel Chaves, José Roberto Ribeiro Bortoleto et al.ZnO and ZnO:Al are wide-bandgap semiconductors which have many applications, mainly as transparent conducting ﬁlms. Thin films of these compounds were deposited onto glass and silicon substrates by RF magnetron sputtering for the investigation of structural and optical characteristics. The XRD results show that the films present wurtzite structure. The formation of a polycrystalline film having a preferential crystallographic orientation … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 5 Oct 2017 · 7,855 accessesView PDF Cite
