CV

Research in the Gajbhiye group combines the use of synthetic, spectroscopic, magnetic, dielectric, and electrochemical experiments to advance the development of new multifunctional inorganic nanoma-terials for spintronics, storage & memory devices, catalysis, contrast agents for MRI and Flouroscence imaging and energy conversion technologies. This research has components of inorganic, physical and materials chemistry cutting across all the interdisciplinary areas.
       Nanoscience is the science of manipulating and controlling things on a small length scale of the materials; a scale of the order of size of the atoms and molecules. The technology behind the applications of materials in our lives is the nanotechnology. At present, nanotechnology is recognized in all fields of science and engineering.
       Our research emphasizes application of a diverse array of complementary physical techniques to probe the electronic structures and physical properties of the new materials that we develop. Core experiments include X-ray diffraction, Fourier transform infrared, photoluminescence, Raman, X-ray photoelectron, Mössbauer spectroscopy, Electron paramagnetic resonance, and SQUID magnetometry, all over broad temperature ranges. Cyclic voltammetry and potentiometry are also used for the electrochemical lithium ion intercalation / de-intercalation characterization.
      Our group has a broad interest in areas: Self-assembly of monodispersed metal nanoparticles: Co, Fe, Ni, Ag, Co-Pt, FePt, and composites.Electronic and magnetic properties of nanostructured transition metal nitrides, oxides [Garnets, Spinel and Hexagonal Ferrites]. In depth study of defect chemistry in variety of morphologies of nanostructured CuO and TiO2 controls structure-property relations used for diluted magnetic semiconductor applications.
