Equilibrium and kinetic studies on complex formation and decomposition and the movement of Cu(2+)metal ions within polytopic receptors.
Potentiometric studies carried out on the interaction of two tritopic double-scorpiand receptors in which two equivalent 5-(2-aminoethyl)-2,5,8-triaza[9]-(2,6)-pyridinophane moieties are linked with 2,9-dimethylphenanthroline (L1) and 2,6-dimethylpyridine (L2) establish the formation of mono-, bi- and trinuclear Cu(2+) complexes. The values of the stability constants and paramagnetic (1)H NMR s...
متن کاملPhysical Chemistry Studies of Acid Dye Removal from Aqueous Media by Mesoporous Nano Composite: Adsorption Isotherm, Kinetic and Thermodynamic Studies
In this research, SBA-15/Polypyrrole (SBA-15/PPy) mesoporous nanocomposite was synthesized, characterized and applied for Acid Blue 62 (AB62) adsorption as a textile dye from aqueous solution. In order to evaluate the structural properties of synthesized adsorbent, FT-IR, FESEM and TEM images, XRD, and BET techniques were applied. Some parameters such as pH, dosage, and time which affect the ba...
متن کاملA TWO-STAGE DAMAGE DETECTION METHOD FOR LARGE-SCALE STRUCTURES BY KINETIC AND MODAL STRAIN ENERGIES USING HEURISTIC PARTICLE SWARM OPTIMIZATION
In this study, an approach for damage detection of large-scale structures is developed by employing kinetic and modal strain energies and also Heuristic Particle Swarm Optimization (HPSO) algorithm. Kinetic strain energy is employed to determine the location of structural damages. After determining the suspected damage locations, the severity of damages is obtained based on variations of modal ...
متن کاملA computational approach to the structural analysis of uncertain kinetic systems
A computation-oriented representation of uncertain kinetic systems is introduced and analysed in this paper. It is assumed that the monomial coefficients of the ODEs belong to a polytopic set, which defines a set of dynamical systems for an uncertain model. An optimization-based computation model is proposed for the structural analysis of uncertain models. It is shown that the so-called dense r...
متن کاملThe Kinetic and Thermal Degradation Studies of N-(4-Acetyl-phenyl)-acetimidic Acid Pyridine-3-yl ester Metal(II) Complexes
Schiff base complexes of transition metals are of particular interest to inorganic chemists because of their structural, spectral and chemical properties, which are often strongly dependant on the nature of the ligand structure. Large number of metal (II) complexes with Schiff-base ligands has been extensively studied for their interesting structural specialties, applications and properties. Th...
