Pelletized silica and amine composites for CO2 capture via adsorption

Knowles G.P., Vogt C., Chaffee A.L., Cooperative Research Center for Greenhouse Gas Technologies, AU

Solid amine sorbent powders are of broad interest to facilitate CO2 capture towards reducing atmospheric greenhouse gas. It is recognized, however, that pelletized rather powdered adsorbents are required for industrial adsorption separation processes. “Molecular basket” [...]

Plasma Treatment of Nanofillers for Polymer Nanocomposites

Ritts A.C., Yu Q., Li H., University of Missouri-Columbia, US

Nanofillers were functionalized with amine groups using low-temperature plasma to enhance dispersion and interfacial tension with Epon 815C resin. The amine groups remained on the coating surface were anticipated to strengthen the interfacial interactions through [...]

Sidewall Functionalization of Single-Walled Carbon Nanotubes through C-N Bond Forming Substitution Reactions of Fluoronanotubes

Stevens J., Kini V.U., Huang A., Chiang I.W., Derrien G.A., Khabashesku V.N., Margrave J.L., Rice University, US

Because of the high reactivity of C-F bonds on the sidewalls of single-wall carbon nanotubes, fluorinated SWNTs (fluoronanotubes) can be used as precursors for further derivatization. One such reaction is to replace the fluorine with [...]
