Philosophy & Scope

Nanocrystals and Nanomagnetism

Prof. Kannan M. Krishnan (Principal Investigator)

  • Chemical synthesis of metallic/oxide nanocrystals with controlled morphologies (alloys, core-shell structures), narrow size distributions, well-defined shapes and functionalized surfaces.
  • Studies of self-organization in weakly interacting systems. Ferrofluids and liquid crystals.
  • Fundamental investigations of their static/dynamic magnetic behavior as a function of assembly, dimensionality, inter-particle interactions and surface functionalization.
  • Phase stability and coupled properties in nanocrucibles.
  • Magnetic and spin-transport in MNP-polymer hybrids
