Research ArticleOpen accessIn the abstractSynthesis and Characterization of Organotin(IV) Complexes Derived of 2-amino-5-nitrobenzoic Acid: In vitro Antibacterial Screening ActivityYip-Foo Win, Siang-Guan Teoh, M. R. Vikneswaran et al.Problem statement: Tremendous studies have been carried out on organotin(IV) complexes derivatives of carboxylate anions. However, the synthesis and characterization as well as the in vitro antibacterial screening activity of organotin(IV) carboxylate derived of 2-amino-5-nitrobenzoic acid have not been carried out. Approach: Organotin(IV) carboxylate complexes derivative of 2-amino-5-nitrobenzoic acid, 2-NH2-5-NO2-C6H3COOH have been successfully synthesized. The acid and complexes obtained were … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 8,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotostability of Ponceau 2R Doped Thin Film Sol-Gel Silica as Luminescent Solar CollectorS.M. RedaProblem statement: Current researches had shown that the photostability of a luminescent solar collector depend on the method of its preparation and type of using dye. This research therefore aimed at studying the stability of luminescent solar collector prepared by sol-gel spin coating method using Ponceau 2R. Approach: The effect of silica matrix on the photostability and fluorescence properties of … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 7,222 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Organotin(IV) Complexes Derived of 3-(Dimethylamino)benzoic Acid: Cytotoxic Assay on Human Liver Carcinoma Cells (HepG2)Yip-Foo Win, Siang-Guan Teoh, Tengku-Sifzizul Tengku-Muhammad et al.Problem statement: Many studies have been carried out on organotin(IV) complexes derivative of carboxylate anions. However, the synthesis and characterization as well as the cytotoxic assay of organotin(IV) carboxylate derived of 3-(dimethylamino)benzoic acid have not been studied. Approach: Organotin(IV) carboxylate complexes derivative of 3-(dimethylamino)benzoic acid, 3-[N(CH3)2]C6H4COOH have been successfully synthesized.
