Current Research
Crystal structure and defect structure study of metallic materials by various transmission electron microscopy (TEM) techniques including high resolution (0.19 nm), weak beam imaging , nano-diffraction and convergent beam electron diffraction, EELS mapping, development of new TEM techniques such as resolution extension by imaging processing, selected reflection imaging of nanostructured materials, magnetic domain imaging by differential phase contrast, development of new high temperature structural materials, high temperature nanostructured materials, high temperature permanent magnet, and nanostructure design of thin films by laser surface treatment and patterning.
