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 PDFCite
Research ArticleOpen accessIn the abstractANTICONVULSANT AND NEUROTOXICITY EVALUATION OF SOME NEWLY SYNTHESIZED THIAZOLYL COUMARIN DERIVATIVESM. Faiz Arshad, Nadeem Siddiqui, Ahmed Elkerdasy et al.The present series of compounds were synthesized with the aim to develop newer anticonvulsant agents that are comparatively more efficacious and safer than the currently used anticonvulsant agents. Various thiazolyl coumarins were synthesized by the reaction of 3-(bromoacetyl)-2H-chromen-2-one with different substituted aryl thiourea. The structures of the synthesized compounds were confirmed by spectral data and elemental analyses. Compounds were tested … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 2 · 26 Mar 2014 · 7,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractCYTOTOXICITY AND MODE OF CELL DEATH INDUCED BY TRIPHENYLTIN (IV) COMPOUNDS IN VITRONormah Awang, Zalila Abdul Aziz, Nurul Farahana Kamaludin, Kok Meng ChanA series of newly synthesized organotin (IV) with N-alkyl-N-phenyldithiocarbamate ligands namely triphenyltin (IV) ethylphenyldithiocarbamate (compound 1) and triphenyltin (IV) butylphenyldithiocarbamate (compound 2) were assessed for their cytotoxic effect against HT-29 human colon adenocarcinoma cells and human CCD-18Co normal colon cells. The cytotoxicity of these organotins in both cells was assessed using 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazholium bromide (MTT) assay upon 24 h treatment. … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 15 Mar 2014 · 8,746 accessesView PDFCite
