Analysis of triethanolamine in trass cement pastes by voltammetric methods
Triethanolamine (TEA) in trass cement pastes has been analyzed by the Square Wave Voltammetric (SWV) technique. It has been observed that the adsorption effect of TEA on the trass cement increases with time and the adsorption ... -
Analysis of triethanolamine in white cement pastes by voltammetric methods
Triethanolamine (TEA) in cement paste has been analysed by square wave voltammetric technique. The technique is sensitive for the quantitative determination of small amounts of TEA. The percentage of the adsorbed TEA is ... -
bis(nicotinamide) and bis(N,N-diethyl nicotinamide) p-hydroxybenzoate complexes of Ni(II), Cu(II) and Zn(II) - Spectrothermal studies
Icbudak, H; Heren, Z; Kose, DA; Necefoglu, H (Kluwer Academic Publ, 2004)The mixed-ligand p-hydroxybenzoate complexes of Ni(II), Cu(II) and Zn(II) with nicotinamide and N, N-diethylnicotinamide were synthesized and characterized by elemental analysis, magnetic susceptibility measurements and ... -
Decomposition pathway of diaquabis(N,N '-dimethyl-1,2-ethanediamine)Ni(II) acesulfamate - Thermal and mass spectroscopic data
Icbudak, H; Heren, Z; Uyanik, A; Odabaşoğlu, Mustafa (Springer, 2005)Prediction of the thermal decomposition pathway of the metal complexes is very important from the theoretical and experimental point of view to determine the properties and structural differences of complexes. In the ... -
The influence of ethanolamines on the hydration and mechanical properties of Portland cement
The effect of ethanolamines-monoethanolamine (MEA), diethanolamine (DEA), triethanolamine (TEA)-on the hydration, mechanical and surface properties of the white Portland cement pastes (white PC) has been investigated. The ... -
The influence of ethanolamines on the surface properties of Portland cement pastes
The effect of ethanolamines-monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA) -on the pore-size distribution of the white Portland cement pastes (white PC) has been investigated. The cement pastes with ... -
Redetermination of trans-diaquabis(picolinato-kappa N-2,O)cobalt(II) dihydrate
Heren, Z; Ersanli, CC; Keser, C; Iskeleli, NO (Int Union Crystallography, 2006)The crystal structure of the title compound, [Co(C6H4NO2)(2)(H2O)(2)]center dot 2H(2)O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31-34; Lumme et al. (1969). ... -
Thermal behaviour of some azo dyes containing sterically hindered and water-soluble groups
Kocaokutgen, H; Heren, Z (Scientific Technical Research Council Turkey, 1998)Thermal behaviour of six azo dyes containing steric hindered groups such as tert-butyl, sec-butyl and isopropyl, were investigated by means of thermogravimetry (TG), differential thermal analysis (DTA) and differential ... -
trans-Diaquabis(ethylenediamine)zinc(II) 2-(sulfanilamido)pyrimidine monohydrate
In the title compound, [Zn(C4H8N4)(H2O)(2)](C10H9N4O2S)(2) (H2O)-H-., the Zn-II ion is octahedrally surrounded by two water O atoms [Zn-O = 2.68 (2) and 2.49 (2) angstrom] and the four N atoms of two ethylenediamine ...
