C 60 nanowhiskers (NWs) containing N@C 60 were prepared by a liquid–liquid interfacial precipitation method. The ESR spectra of N@C 60 /C 60 NWs showed broader lines than N@C 60 /C 60 powder indicating that N@C 60 acts as a non-destructive structural probe for fullerene nanomaterials.
The diameters of C 60 nanowhiskers (C 60 NWs), which are prepared by a simple liquid–liquid interfacial precipitation method, can be tuned appropriately by controlling the area size of liquid–liquid interface. The diameters of C 60 NWs decrease with decreasing the area size of liquid–liquid interface. The electronic spectra of C 60 NWs show a dependence on the diameters...
Endohedral metallofullerene nanowhiskers and nanosheets were prepared using pristine Sc 3 N@C 80 by liquid–liquid interfacial precipitation. This means that it is possible to prepare endohedral metallofullerene structures without using chemical derivatization techniques. They were characterized using scanning and transmission electron microscopy and atomic force microscopy. The morphology...
Purified single-walled carbon nanotubes (SWCNTs) were produced using the arc-discharge method with a combination of air oxidation and dispersion–centrifugation processes in a tetrahydrofuran solution containing an amine as a dispersant. Subsequently, SWCNT samples were analyzed using thermo gravimetric analysis, vis-near infrared absorption spectroscopy, scanning electron microscopy, and Raman spectroscopy...
Optical absorption and resonant Raman spectra are proven to be convenient and effective to monitor the centrifugal fractionation and to evaluate the quality of soluble single-walled carbon nanotubes (SWNTs) achieved by inorganic oxidation and organic functionalization. Through a systemic study of a series of centrifuged solutions, we confirmed that heavily functionalized amorphous carbon was fractionated...
