Self-assembled titania-silica-sepiolite based nanocomposites for water decontamination
(Royal Soc Chemistry, 2009)This work describes the preparation of microchannel structured monolithic pieces by the "ice-segregation induced self-assembly'' (ISISA) process. The monoliths exhibit a hierarchical structure composed of homogeneously ... -
A semi-empirical and density functional theory study of 2,2',3,4-tetrahydroxy-3'-sulpho azobenzene derivatives and their zirconium complexes
(2013)In this study, certain theoretical properties of three tetrahydroxyazo derivatives and their zirconium complexes, such as stability, reactivity, geometry and energy have been calculated by MOPAC2009 with the PM6 method and ... -
Separation of catechins and methylxanthines in tea samples by capillary electrochromatography
(2009)In this paper, the simultaneous separation of several polyphenols such as (+)-catechin, (-)-epicatechin, (-)-epigallocatechin, theophylline, caffeine in green and black teas by capillary electrochromatography (CEC) was ... -
Spectrophotometric determination of the acidity dissociation constants of symmetric Schiff base derivatives
(Gazi University Eti Mahallesi, 2014)In this study, the acidity constants of series symmetric Schiff base derivatives have been determined using the UV-visible spectrophotometric method at a temperature of 25(±0.1) °C. The deprotonated acidity constants (pKa) ... -
Structural studies of water-soluble ß-brominated manganese porphyrins: Stabilities of MnTDCSPPBr8 and MnTSPPBr8 as homogeneous and supported reagents toward hydrogen peroxide and sodium hypochlorite
(2001)This article describes the structural stabilities of [2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetrakis(2,6-dichloro-3- sulfonatophenyl)porphinato]manganese(III) X (where X = H2O and/or OH-, depending on pH) (MnTDCSPPBr8) ... -
Synthesis and antimicrobial investigation of some 5H-pyridazino[4,5-b] indoles
(2013)Synthesis and in vitro antimicrobial activities are reported for a series of 1,3,5-substituted 4-oxo-3,4-dihydro- 5H -pyridazino[4,5- b]indole derivatives. Corresponding pyridazino[4,5- b]indoles were prepared from ethyl ... -
Synthesis and Characterization of Two New Thiophene Acetyl Salicylic Acid Esters and their ortho-and para-effect on Anticancer Activity
(Bentham Science Publ LTD, 2017)Objective: The present study aimed to explore the cytotoxic effect of ortho-and para-positional isomers of thiophene acetyl salicylic acid esters against cancer and normal cell lines. Method: Two new thiophene-2-acetic ... -
Synthesis of some alkylaminothiophene derivatives from 3,4-dibromothiophene and their theoretical calculations
(Elsevier Ltd, 2019)In this study, the copper catalyzed amination reactions of 3,4-dibromothiophene with some primary, cyclic and acyclic secondary amines were investigated to prepare novel electron rich-thiophenes which are expected to be ... -
The synthesis, characterization and structural analysis of a Co(III) complex of 1,10-phenanthroline and perfluorosebacic acid, [Co(HL)(phen) 2(H2O)]L·H2O
(Verlag der Zeitschrift fur Naturforschung, 2006)The hexacoordinated mononuclear Co(III) complex 1, [Co(HL)(phen) 2(H2O)]L·H2O, with the mixed ligands (H2L = HO2C(CF2)8CO2H and 1,10-phenantroline) has been synthesized and characterized by elemental analysis, IR and UV/vis ... -
Validated UV-Vis Spectrophotometric Method for the Determination of Copper using 2,3,4,6/-Tetrahydroxy-3/-Sulfoazobenzene in Real Samples
(Chemical Society of Pakistan, 2018)A selective and sensitive spectrophotometric method has been proposed for the determination of copper by forming red-brown chelate at pH 3.5 (3-4) with 2,3,4,6/-tetrahydroxy-3/-sulfoazobenzene (THSA). Molar absorptivity ...
