Grazing incidence small angle X-ray scattering (GISAXS) measurements reveal that superlattices of 1.7 nm diameter, gold (Au) nanocrystals capped with octadecanethiol become significantly more ordered when heated to moderate temperatures (50-60 °C). This enhancement in order is reversible and the superlattice returns to its initially disordered structure(More)
Dodecanethiol-capped gold (Au) nanocrystal superlattices can undergo a surprisingly diverse series of ordered structure transitions when heated (Goodfellow, B. W.; Rasch, M. R.; Hessel, C. M.; Patel, R. N.; Smilgies, D.-M.; Korgel, B. A. Nano Lett. 2013, 13, 5710-5714). These are the result of highly uniform changes in nanocrystal size, which subsequently(More)
Recombinant antibodies and antibody fragments have become powerful tools for therapy, in vivo and in vitro diagnostics, and laboratory research. However, the production of antibody fragments in high yield for preclinical and clinical trials can be a serious bottleneck in drug discovery. This dissertation describes the development of novel screening systems(More)
Acknowledgments I must admit that pursuing my graduate studies here at the University of Texas at Austin gave me a rare opportunity to be under the tutelage of talented professors. However, today I feel chiefly indebted to my advisor Dr. Allan MacDonald for the patience and sincerity he has shown me in regard to this dissertation. I would like to take this(More)
Dedicated to my parents for their never ending love. Acknowledgments I am grateful to my loving mother for enduring all the hardship while bringing up me and my brother; for always being there for us. I am grateful to my dad for taking great care of his family, for providing the best education available to us, for always staying true to his principles(More)
for friendship, moral support and occasional comic relief. support over the years in scheduling classes, purchasing chemicals and equipment, creating reactor cells, fixing computers and providing extra cookies after seminars. Lastly, I would like to thank my parents and brother for their love and support, and Jason for keeping me company during this entire(More)
