Our current interests focus on:
– Identification and quantification of chemical functionalities on the surfaces of carbon materials, including nanotubes
Identification and quantification of functional groups on single-walled carbon nanotubes via fluorescence labeling.

– Photophysical properties of carbon nanotubes
– Carbon nanotube purification methods for the efficient removal of carbon and metallic impurities
Dynamic oxidation, a novel purification method of single-walled carbon nanotubes, being ~10 faster than a traditional isothermal oxidation, yields nanotubes that are nearly free from carbon impurities.
