Synthesis, characterization and comparative thermal degradation study of Co(II), Ni(ΙΙ) and Cu(II) complexes with Asparagine and Urea as mixed ligands

Abstract: New Co(II), Ni(II) and Cu(II) complexes with urea and asparagine as ligands have been synthesized in (M:L1:L2) molar ratio (where M= Co(II), Ni(II) and Cu(II), L1 = urea, and L2 = asparagine) then identified by micro analyses, molar conductance measurements

Physicochemical and biological activity studies on complexes of some transition elements with mixed ligands of glycine and urea

Abstract: The reaction of urea (ur) and glycine (gly) with the metal ions Co(ΙΙ), Ni(ΙΙ) and Cu(ΙΙ) in ethanolic solution of 1M:1L1:1L2 molar ratio (where M= Co(II), Ni(II) and Cu(II), and L1 = urea L2 = glycine) led to the preparation of complexes of the general formu

Simple, fast and inexpensive method for determination of ranitidine hydrochloride based on conductometric measurements

Abstract: This work aims the development and optimization of an alternative method for ranitidine hydrochloride (RAN-HCl) determination. The proposed method was based on conductometric titration of RAN by precipitation of AgCl solid using a solution of AgNO3 as titrant

Dark breather using symmetric morse, solvent and external potentials for DNA breathing

Abstract: We analyze the dynamics and the quantum thermodynamics of DNA in Symmetric-Peyrard-Bishop-Dauxois model (S-PBD) with solvent and external potentials and describe the transient conformational fluctuations using dark breather and the ground state wave function
