Creator:: Tseng, Chih-Heng
Abstract:: A key requirement within many microsystem devices is the ability for rapid mixing and gas-liquid absorption. In the past, qualitative results have suggested that micro-manufactured straight-through pores can significantly reduce the pressure drop for gas diffusion across a gas-liquid contactor as compared to the complicated and tortuous flow paths encountered...
Resource Type:: Masters Thesis

Creator:: Carpenter, Trenton James
Abstract:: Through passive adaptation to incidental flow, flexible aerodynamic surfaces exploit effects of increased lift, delayed stall and disturbance rejection. Wings of birds, bats, and insects exhibit these passive effects, and at the same time through the use of structural state feedback sensed from the loads on the wing, active control...

Creator:: Xu, Zhihua
Abstract:: Reverse osmosis (RO) is being increasingly used in treatment of domestic wastewater secondary effluent for potable and non-potable reuse. Among other foulants, dissolved biopolymers, i.e., proteins and polysaccharides, can lead to severe fouling of RO membranes. In this study, the roles of RO membrane surface properties in membrane fouling by...
Resource Type:: Masters Thesis
Full Text:: research has proved that membrane technology, especially reverse osmosis (RU) membrane, can play a key

Creator:: Cappello, Nicholas C.
Abstract:: Understanding the behavior of hydrophobic membranes is important for applications where separating a gas from a liquid-gas mixture is beneficial. For example, in-situ vapor extraction can be used in microscale heat sinks to improve heat transfer and flow stability. In this study, gas is experimentally evaluated flowing through flexible polytetrafluoroethylene...

Full Text:: Experimental Characterization of Membrane Behavior in Two-phase Gas Extraction Abstract approved: Deborah V

Creator:: McNeff, Patrick Scot
Abstract:: The objective of this paper is to demonstrate a method for mechanically characterizing a 25 μm thick elastoviscoplastic hemodialysis membrane and for quantifying the force required to use that membrane in compression sealing. First, methods are developed for mechanically characterizing the thin elastoviscoplastic membrane. Then, a finite element model is...

Creator:: Wilcox, Joshua Robert
Abstract:: Micro air vehicles (MAV's) and small unmanned aerial vehicles (SUAV) are remotely piloted or autonomous aircraft with a take-off mass range between 50 g and few kilograms. These vehicles, as well as natural fliers such as bats and insects, utilize a variety of elastic wing structures including thin membranes. Over...

Creator:: Quarles, Lucas W.
Abstract:: Contaminants can exist in a wide range of states in aqueous environments, especially in surface waters. They can be freely dissolved or associated with dissolved or particulate organic matter depending on their chemical and physical characteristics. The freely dissolved fraction represents the most bioavailable fraction to an organism. These freely...
