Keith Johnston Research Group (5.414)Nanotechnology/Colloid Science/Interfaces
– Nanotechnology for CO2 Sequestration and EOR(Bryant, Huh, Hirosaki, Milner, Nguyen, Prodanovic)
• Nanoparticle adsorption and transport in porous med.• Electromagnetic imaging• Emulsions/foams for mobility control
– Nanomaterials for electrocatalysis(Stevenson)
• Catalysis- fuel cells, batteries• CO2 reduction to fuels
Pharmaceutical Imaging and Therapeutics– Magnetic/optical/therapeutic nanoparticles -cancer and atherosclerosis(Sokolov, Milner, Feldman (UTHSCSA), Emelianov, Zhang)– Protein drug delivery (subcutaneous delivery)(Jennifer Maynard, Tom Truskett)
Themes:particles synthesis, colloid stabilization,exposed to wide range of colloid scienceantibodies- cell specific imaging and therapyand direct delivery Porous substrates- reservoirselectrocatalyst supports
