Investigating self-assembly of functionalized nanotubes and peptides by tunneling microscopy
Scanning tunneling microscopy (STM) is an ideal tool for probing the chemistry and physics of these types of nanostructures. Building upon on our previous carbon nanotube research, we have investigated thiol and thiophene ...
Impeded photo-oxidation of conducting polymer films using metal nanoshells
Interest in the use of conducting polymers as the active layer in electroluminescent devices has grown steadily over the last decade, and the commercialization of such devices is imminent. The stumbling block to the ...
Controlled multi-step purification of single-walled carbon nanotubes
A controlled and scalable multi-step purification method has been developed to remove iron impurity and non-nanotube carbon materials from raw single-walled carbon nanotubes produced in the HiPco (high pressure CO) process. ...
