Nanoscience


Nanoscience refers to the science of materials having at least one dimension in the range from 1 to 100 nanometers and properties (physical, chemical, and biological) which are fundamentally different from those of the same material in the bulk or molecular form.

In our group, we study nanocrystalline powders, thin solid films and nanowires of different (mainly oxide) materials such as NiO, ZnO, WO3, ZnWO4, CuWO4, etc.


Nanomaterials can be classified according to their dimensionality:

  • 0D: quantum dots and nanoclusters,
  • 1D: nanowires, nanoribbons, and nanotubes,
  • 2D: nanofilms and nanolayers,
  • 3D: nanoparticles and nanocrystals.

    Some examples of nanomaterial studies:
  • Atomic structure relaxation in nanocrystalline NiO studied by EXAFS spectroscopy: Role of nickel vacancies.
  • Static and dynamic structure of ZnWO4 nanoparticles.
  • Confocal spectromicroscopy of amorphous and nanocrystalline tungsten oxide films.
  • X-ray absorption spectroscopy of nanocrystalline iridium oxide thin films.
