COMPLEXATION AND ANTIBACTERIAL STUDY OF 1,3,4-OXADIAZOLE DERIVATIVE
Abstract: New metal complexes of Zn(II),and Ni(II) have been synthesized by reacting metal solutions with the ligand 2,5-substituted 1,3,4-Oxadiazoles in alcoholic medium. Molecular formulae of the complexes were determined and are further characterized by IR spectroscopy, magnetic susceptibility and molar conductance studies. Since two nitrogen atoms coordinate to the metal center, the ligand is termed as bidentate ligand.KEY WORDS: Complexes, Ligands, Transition metal complexes, Oxadiazoles.

Numerical Analysis of Flow Characterization in a Continuous Crystallizer
Abstract: In this work, hydrodynamics in a draft tube continuous crystallizer is analyzed computationally through Ansys CFD to crystallization phenomena. Hindrance to fluid mixing and particle suspension due to vortexing can be overcome by providing baffles. A draft tube ensures that it directs the flow in vertical direction ensuring good axial blending. Here CFD simulations are performed using multiple reference frame (MRF) with sliding mesh approach in transient condition for flow …
