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 ...
Investigation of cross-linking efficiency and its effect on gas transport in polyetherimide/acetylene terminated imide monomer blend membranes
(Georgia Institute of Technology, 1997-12)
Thrombomodulin/heparin functionalized membrane-mimetic assemblies: strategies for generating an actively anti-thrombogenic surface
(Georgia Institute of Technology, 2005-07-20)
It has been postulated that the control of thrombus formation on molecularly engineered surfaces is an important step in developing clinically durable small-diameter vascular prostheses. This has led to designing a ...
Novel Pervaporation for Separating Acetic Acid and Water Mixtures Using Hollow Fiber Membranes
(Georgia Institute of Technology, 2005-06-27)
Commercial pure terephthalic acid (PTA) manufacturing generates process streams mainly containing acetic acid (HAc) and water. A large financial incentive exists to replace the costly and energy intensive distillation ...
Cross-linkable polyimide blends for stable membranes
(Georgia Institute of Technology, 1996-12)
Investigation of Dithiolenes for Propylene/Propane Membrane Separations
(Georgia Institute of Technology, 2007-08-24)
Polyimide membranes containing nickel dithiolenes were investigated for the separation of propylene and propane. Permeation and sorption experiments were conducted as well thermal property analyses. Results indicate that ...
The rheology and phase separation kinetics of mixed-matrix membrane dopes
(Georgia Institute of Technology, 2011-01-18)
Mixed-matrix hollow fiber membranes are being developed to offer more efficient gas separations applications than what the current technologies allow. Mixed-matrix membranes (MMMs) are membranes in which molecular sieves ...
Membranes for olefin/paraffin separations
(Georgia Institute of Technology, 2009-11-10)
The goal of this project was to develop a mixed matrix membrane with enhanced properties for propylene/propane separations. To start with the project, one of the high performance 6FDA based polyimides was identified as the ...
High energy density direct methanol fuel cells
(Georgia Institute of Technology, 2010-11-08)
The goal of this dissertation was to create a new class of DMFC targeted at high energy density and low loss for small electronic devices. In order for the DMFC to efficiently use all its fuel, with a minimum of balance ...
Development of next generation mixed matrix hollow fiber membranes for butane isomer separation
(Georgia Institute of Technology, 2010-10-13)
Mixed matrix hollow fiber membranes maintain the ease of processing polymers while enhancing the separation performance of the pure polymer due to inclusion of molecular sieve filler particles. This work shows the development ...
