Research Interests

Self-assembly of amphiphiles:

Self-assembly of amphiphilic molecules in aqueous and nonaqueous systems and the microstructure characterization using small-angle scattering of X-rays or neutrons. Major interests: (i) formulation of nonionic reverse micelles in nonaqueous media using bio-surfactants (biocompatible and biodegradable); (ii) free structure control of reverse micelles for their application in nanostructured materials synthesis.

Nanostructured crystalline fullerene C60:

Synthesis, characterization, and application of nanostructured crystalline fullerene C60. Major interests: (i) production of nanostructured meso/or microporous single crystalline C60; (ii) investigation of reverse micelle-C60 interactions and the role of reverse micelle on the crystallization of C60 molecules at liquid-liquid interface;
