Computationally Probing the Cybotactic Region in Gas-Expanded Liquids
(Georgia Institute of Technology, 2007-01-03)
Gas-expanded liquids (GXLs) are novel and environmentally benign solvent systems with applications in reactions, separations, nanotechnology, drug delivery, and microelectronics. GXLs are liquid mixtures consisting of an ...
Poly(Methyl Methacrylate) swelling in carbon dioxide at high pressure
(Georgia Institute of Technology, 2000-12)
Measurement of binary phase equilibria and ternary/quaternary gas antisolvent (GAS) system measurement and analysis
(Georgia Institute of Technology, 2004-07-12)
The work conducted in this thesis is two-fold. First, binary vapor liquid equilibria of several solvent/CO2 systems are measured at 40 ?? The systems analyzed are all gas-expanded liquids (GXLs) characterized with a ...
Carbon Dioxide as a Benign Solvent for Homogeneous Catalyst Recovery and Recycle
(Georgia Institute of Technology, 2005-07-19)
We have successfully investigated the use of CO2 as a miscibility switch to create an environment in which we can run a homogeneously catalyzed reaction while maintaining a heterogeneous separation. We explored the use ...
Crosslinked polyimide hollow fiber membranes for aggressive natural gas feed streams
(Georgia Institute of Technology, 2008-12-01)
Natural gas is one of the fastest growing primary energy sources in the world today. The increasing world demand for energy requires increased production of high quality natural gas. For the natural gas to be fed into ...
Role of carbon dioxide in gas expanded liquids for removal of photoresist and etch residue
(Georgia Institute of Technology, 2007-10-08)
Progress in the microelectronics industry is driven by smaller and faster transistors. As feature sizes in integrated circuits become smaller and liquid chemical waste becomes an even greater environmental concern, gas ...
Specific interactions in carbon dioxide + polymer systems
(Georgia Institute of Technology, 2008-01-04)
Specific Interactions in Carbon Dioxide + Polymer Systems Anupama Kasturirangan 163 Pages Directed by Dr. Amyn S. Teja Weak complex formation in CO2 + polymer and CO2 + copolymer systems containing C=O and ...
The use of layered double hydroxides as adsorbents for carbon dioxide
(Georgia Institute of Technology, 2003-08)
Designing for sustainability with CO2-tunable solvents
(Georgia Institute of Technology, 2007-11-14)
Developing greener, more efficient, and less energy-intensive processes will lead the chemical industry into a more sustainable future. Gas-expanded liquids (GXLs) form a unique class of environmentally benign and tunable ...
Polymeric membranes for super critical carbon dioxide (scCO2) separations
(Georgia Institute of Technology, 2009-03-23)
Providing an energy efficient recycle for the Teflon® synthesis process is of great interest due to environmental and economic reasons. This recycle step involves separating CO2 from a stream containing scCO2 and valuable ...
