Mammalian cell survival and processing in supercritical CO(2).
We demonstrate that mammalian cells can survive for 5 min within high-pressure CO(2)(.) Cell survival was investigated by exposing a range of mammalian cell types to supercritical CO(2) (scCO(2)) (35 degrees C, 74 bar; 1 bar = 100 kPa) for increasing exposure and depressurization times. The myoblastic C2C12 cell line, 3T3 fibroblasts, chondrocytes, and hepatocytes all displayed appreciable but ...
متن کاملDiffusion of gaseous and supercritical CO 2 through polycarbonate 1
Submitted for the MAR13 Meeting of The American Physical Society Diffusion of gaseous and supercritical CO2 through polycarbonate 1 MICHAEL GOODMAN, RAHMI OZISIK, Rensselaer Polytechnic Institute — The design of polymeric materials for applications such as separation membranes and nanostructured foams requires prediction of gas transport properties under a wide range of pressures. In the curren...
متن کاملMolecular simulation of swelling and interlayer structure for organoclay in supercritical CO(2).
In this work, Monte Carlo simulations have been carried out to investigate the swelling stability and interlayer structures of alkylammonium-modified montmorillonite both in vacuum and in supercritical CO(2) (scCO(2)) fluid. In the vacuum (dry) condition, the stable spacing for this kind of organoclay was determined based on the energy minimum. In the stable spacing, the corresponding interlaye...
متن کاملMetal ion extraction using newly-synthesized bipyridine derivative as a chelating reagent in supercritical CO(2).
4,4'-Bis(dihexylaminocarbonyl)-2,2'-bipyridine (BDC-Bipy) was synthesized and studied systematically as a chelating reagent for metal ions extraction in supercritical CO(2). The compound showed high extraction efficiency for Co(2+) (100%), Cu(2+) (100%), Cd(2+) (98.2%), and Zn(2+) (100%) ions and good extraction efficiency for Sr(2+) (79.4%) and Pb(2+) (89.8%) when the extraction was performed ...
متن کاملExtractability of metals in municipal solid wastes fly ash using supercritical CO(2) containing Cyanex 302.
The extraction of lead from fly ash produced during the thermal treatment of municipal solid wastes was studied using supercritical carbon dioxide (SC-CO(2)) and Cyanex 302 (bis(2,4,4-trimethylpentyl)monophosphinic acid). The extraction of lead from the fly ash was carried out in a 5 cm(3) internal volume reaction vessel under static extraction conditions at 323 K, and 24 MPa for 1 h. The extra...
