[ 1 ] - A Thermodynamic Study of Complex Formation between 15-Crown-5 with Mg2+, Ca2+, Sr2+ and Ba2+ in Acetonitrile Methanol Binary Mixtures Using Conductometric Method

The complexation reactions between Mg2+, Ca2+, Sr2+ and Ba2+ metal cations with 15-crown-5 (15C5) were studied in acetonitrile (AN)-methanol (MeOH) binary mixtures at different temperatures using conductometric method. 15C54 forms 1:1 complexes with Mg2+, Ca2+ and Sr2+ cations in solutions. The Ma2+ cati...

[ 2 ] - Competitive Spectrophotometric Study of Copper, Zinc and Cadmium With 18C6 Using TAR as a Colorimetric Complexing Agent in Methanol

A Competitive spectrophotometric method has been used for the study of complexation between Cu2+, Zn2+ and Cd2+ (M) and 18-crown-6(18C6, B) in methanol using 4-(2-thiazolylazo) resorcinol (TAR, HL) as the colorimetric complexant. Absorption spectra of the species in the M-TAR-18 C6 system at a various concentrations of 18C6 showed no formation of ternary com...

[ 3 ] - Behenic Acid Monolayer and Bilayer Assemblies- A Study of Concanavalin A (Con A) Adsorption and its Interaction with Dextran Using Surface Plasmon Resonance Spectroscopy and Microscopy

Deposition of behenic acid (B.A) mono and bilayers onto gold coated surfaces was performed by Langmuir-Blodget dip-casting technique. Surface Plasmon resonance (SPR) and ellipsometry methods were employed for investigation of the monolayer and bilayer films. The adsorption of the biologically important molecule Concanavalin A (Con A) from bulk solution to these monolayers and bilayers as we...
