Complexation of thorium(IV) with malonate at variable temperatures

Complexation of L-arginine and L-lysine by p-sulphonatocalix (61 arene in aqueous solution at different temperatures

The interaction of p-sulphonatocalix [6] arene towards L-arginine and L-lysine has been studied inacidic aqueous solution (p1-1 2) using UV-Vis spectrophotometric titration technique. The psulphonatocalix[6] arene was found to be able to form 1:1 complexe with amino acids in water.The values of the association constant were determined at different temperatures to evaluate thethermodynamic funct...

Complexation of Bis(acetylacetonate)oxovanadium(IV) with D–penicillamine at neutral medium

Neutral bidentate N-O type complexe of VO(II) has been synthesized through condensation of Dpenicillamine,(D-H2Pen), with Bis(acetylacetonate)- oxovanadium(IV),[VO(acac)2], at neutralmedium . The established schiff base(NO type) complex was characterized on the basis of IR andmass spectroscopy techniques.Besides,D-H2Pen binding behavior to[VO(acac)2] has been studiedin thermodynamic viewpoint u...

Magnetohydrodynamic (MHD ) Plane Poiseuille Flow With Variable Viscosity and Unequal Wall Temperatures

Complexation and Adsorption of [Eu]Eu to Superplasticizers and Bentonite at Variable Salt Concentrations

The preferred method for the storage of spent nuclear fuel (HLW) is the disposal in deep geological formations. The repository will consist not only of the geological barrier but also of an engineered barrier and has to isolate the waste for at least 10 years from the biosphere [1]. In this barrier, several materials like concrete or bentonite are effective in retention of radionuclides. In mod...

Calculation of MnO Activity in Aluminate Slags at Various Temperatures

In this research, the activity of MnO, produced during steel making in aluminate-rich slags, was investigated. According to thermodynamic equations and mathematical calculation, a series of relations was obtained for evaluation of oxide activity using Masson’s theory. The obtained relations were solved according to Levenberg- Marquardt method and using Matlab software. The results were correlat...
