  1. Exploring Transition Metal Oxides Towards Development of New Functional Materials : Lithium-ion Battery Cathodes, Inorganic Pigments And Frustrated Magnetic Perovskite Oxides

    Laha, Sourav
    Transition metals (TMs) are ‘elements whose atoms have partially filled d-shell, or which can give rise to cations with an incomplete d-shell’. In TMs, the d-shell overlaps with next higher s-shell. Most of the TMs exhibit more than one (multiple) oxidation states. Some TMs, such as silver and gold, occur naturally in their metallic state but, most of the TM minerals are generally oxides. Most of the minerals on the planet earth are metal oxides, because of large free energies of formation for the oxides. The thermodynamic stability of the oxides is determined from the Ellingham diagram. Ellingham diagram shows...

  2. Synthesis And Self-Assembly Properties of Chiral Diketopyrrolopyrrole Based Copolymers

    Maity, Soham
    Applications of conjugated polymer (CPs) in optoelectronic devices are critically depend on nature of thin film morphology. In thin film of CPs, the distribution of conjugation length is highly heterogeneous because of conformational defects, distortions of polymer chain and aggregates. A greater understanding of the self-assembly properties of polymer in solution, in particular control over aggregation leads to richer description of electronic properties and hence reproducible fabrication of thin film devices. Recently, chiral CPs have attracted profound interest because of their promising chiroptical properties in thin films and easy control over the selective agglomeration process. In this thesis, we have...

  3. Crystal Engineering : From Molecule To Crystal Structure Landscape

    Dubey, Ritesh
    Crystal engineering underlies the essence of natural affiliation between the molecule on the one side and the crystal as a supramolecular assembly on the other. Molecular recognition is the fundamental cause for this efficient transformation and if we consider the crystal as a supramolecular entity then it is not at all difficult to conceive crystallization as an outstanding example of molecular recognition. In general, organic compounds often facilitate closed packed crystal structures as described by A. I. Kitaigorodskii in the form of the close packing principle but based on chemical features, there is still a small window to understand, to...
