Calorimetric evidence of the formation of half-cylindrical aggregates of a cationic surfactant at the graphite/water interface
Article Abstract:
Research was conducted to examine the adsorption of a cationic surfactant, dodecyltrimethylammonium bromide from aqueous solutions on graphitized carbon black from 288.15 to 318.15 K by a versatile, automated measuring system. The adsorption mechanism and the morphology of the high-density adsorbate structure were analyzed in relation to the classical reorientation model. Results are in good agreement with the formation of C12TAB half-cylinders at the graphite/water interface.

A highly selective, one-pot purification method for single-walled carbon nanotubes
Article Abstract:
The study emphases on a newly developed one-pot and highly-selective chemistry, which can be widely used for removing the residual catalysts and other impurities from several single-walled carbon nanotubes (SWNTs). The methodology described is highly solution-based and uses an inexpensive green oxidant hence can be easily used for scaling into an industrially viable process for carbon nanotube purification.
