Computational Study Of Droplet And Capsule Flow In Channels With Inertial Effects, Robert Carroll
Computational Study Of Droplet And Capsule Flow In Channels With Inertial Effects, Robert Carroll
Doctoral Dissertations
The flow of droplets and capsules in channels is important for a variety of industrial and biological applications. Droplet flow is common in microfluidic devices and emulsion processing as well as oil recovery from porous materials. Capsules are used to encapsulate sensitive materials and can be used to study the mechanical properties of biological cells. A computational method was developed to study the two-phase flow of drops with and without surfactants, and capsules surrounded by a thin elastic membrane. This new computational method allowed for the inclusion of inertial effects on droplet and capsule flow which has not received much …
Overexpression And Characterization Of A Laccase From Geobacillus Thermoglucosidasius, Anthony Castagnaro
Overexpression And Characterization Of A Laccase From Geobacillus Thermoglucosidasius, Anthony Castagnaro
Master's Theses and Capstones
The use of enzymes as industrial oxidants has become popular due to their high substrate specificity and mild reaction conditions. Specifically, laccases are multi-copper oxidases that can oxidize a disparate range of organic substrates using oxygen and producing water as a byproduct without requirement for additional reactive compounds. Currently, all laccases used in industrial processes are fungal in origin. Although fungal laccases have high activities under near-ambient conditions, their use is limited at higher temperatures. Also, expression of fungal laccases in heterologous hosts is limited due to incorrect glycosylation. Bacterial laccases are much easier to express heterologously and are more …

Encapsulation Of Anti-Traction Material, Brian Zukas
Master's Theses and Capstones
Anti-Traction Material (ATM) is a highly viscous and viscoelastic aqueous polymer solution that has been demonstrated as an effective area denial, non-lethal technology. However, current means of dispersing ATM require on site pumping of the reagents and large tanks for reagent storage. The moment that ATM is dispensed onto a surface it also begins to dry out, starting the clock on the time it is effective. To counter these problems, ATM has been successfully encapsulated using the inverse alginate gelation technique. To produce capsules of ATM, a novel method of producing drops of the highly viscous and viscoelastic ATM solution …
