Research Interests:

1. Controlled synthesis, characterization and physical properties of one-dimensional (1D) semiconductor nanostructures (including nano-heterostructures);

2. Electronic structures and optical properties of nanostructures via X-ray absorption fine structure (XAFS) and X-ray excited optical luminescence (XEOL), and focusing on the spectromicroscopy studies of nanostructures by scanning transmission X-ray microscopy (STXM).

3. Biomineralization - studying the effect of biomolecules and biosubstrates on the mineralization of hydroxyapatite (HAP) and calcium carbonate.

Synchrotron Facilities Used For My Research:

1. Variable Line Spacing Plane Grating Monochromator (VLS-PGM), Canadian Light Source, The University of Saskatchewan, Canada.

2. High Resolution Spherical Grating Monochromator (SGM), Canadian Light Source, The University of Saskatchewan, Canada.

3. Soft X-ray Microcharacterization Beamline (SXRMB), Canadian Light Source, The University of Saskatchewan, Canada.

4. Soft X-ray Spectromicroscopy (SM), Canadian Light Source, The University of Saskatchewan, Canada.

5. Pacific North Consortium X-ray Science Division (PNC/XSD), Advanced Photon Source, Argonne, IL USA.

6. Beamline 8.0.1 Soft X-ray fluorescence (SXF), Advanced Light Source, Berkeley, USA.


Synthesis of nanomaterials: vapor-phase and liquid-phase methods such as thermal evaporation, chemical vapor deposition, sol-gel, anodic alumina oxide (AAO) template, molten salt, and hydrothermal methods.

Operation of equipments: Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), X-ray Diffraction (XRD), Dynamic Light Scattering (DLS), Field Emission (FE) system, and Fourier Transform Infrared spectroscopy (FT-IR).
