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 ...
Fundamentals of transport in poly(ethylene terephthalate) and poly(ethylene furanoate) barrier materials
(Georgia Institute of Technology, 2015-04-03)
The increasing use of polymeric materials in food packaging applications is due to many factors; however, most are related to cost. While poly(ethylene terephthalate) (PET) is currently the industry standard for soft-drink ...
Formation of electrically condution polymer blends using supercritical carbon dioxide
(Georgia Institute of Technology, 1998-05)
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 ...
Identifying CO₂ dissociation pathways on stepped and kinked copper surfaces using first principles calculations
(Georgia Institute of Technology, 2012-04-06)
Three Miller index surfaces of copper, Cu(111), Cu(211), and Cu(643) were evaluated for spontaneous carbon dioxide dissociation. DFT (Density Functional Theory) was used to characterize the initial and final adsorption ...
