Department of Chemistry, A. P. S. University, Rewa-486 003, Madhya Pradesh, India E-mail : rnp64@ymail.com Department of Chemistry, MGCGV, Chitrakoot, Satna-485 334, Madhya Pradesh, India Manuscript received online 14 December 2016, accepted 15 December 2016 Five vanadium(IV) complexes [VO(Aspa)(L)], where Aspa = L-aspartic acid, L = imidazole, 2-methylimidazole, 2-ethylimidazole, 2-methylbenzimidazole and 1,10-phenanthroline, have been synthesized and characterized by microanalysis, FTIR, UV-Visible, ESR spectroscopy and cyclic voltammetry. The geometrical parameters of these complexes were performed by DFT and TD-DFT methods. The theoretical calculations confirm that the vanadium(IV) center exhibited square pyramidal geometry in 1-4 and distorted octahedral geometry in 5. The paramagnetic resonance g-factor and the magnetic susceptibilities (magnetic moments) of vanadyl complexes are discussed. The complexes were also tested for their in vitro antidiabetic activity (α-glucosidase inhibition activity). The complexes exhibited moderate antidiabetic properties.

J. P. Nagar, Uttar Pradesh, India Manuscript received 09 April 2012, accepted 12 April 2012 Nano Technology is growing at a faster pace and is leaving its impact on our day to day life. Nano materials are undoubtedly the most valuable resource in the development of this technology. So it is very essential to develop new methods to produce these materials. Keeping this view in mind CNTs were made by using protein present in spinach and metal ions as catalyst. The chemical compound, so formed was decomposed at different temperatures to obtain CNTs. These CNTs were characterized using SEM and Micro Raman spectroscopy.
