Novel architecture for entrapment of elastomeric membranes in microfluidic systems

Creator:: Blackwell, Edward P.
Abstract:: This thesis presents a novel microlamination architecture that enables the large scale integration of valves into low cost micro energy and chemical systems via membrane entrapment. Polycarbonate layers embossed with microfluidic channels were bonded by ultrasonic welding of raised embossed protrusions that penetrate though the PDMS membranes. The bonding pressure...

Modeling and development of fabrication method for embedding membrane based microvalve in bulk microfluidic device

Creator:: Abhinkar, Bindiya S.
Abstract:: PDMS membrane-based microvalves are becoming increasingly more important for the control of fluid flow within MECS applications such as microreactors used to synthesize nanoparticles and biological macromolecules. The motivation for pursuing PDMS membrane-based microvalves is for implementing a plug flow microreactor to simulate slug flow yielding a narrower residence time...

Design of a single lamina for a microchannel dialyzer with a focus on bubble removal

Creator:: Mohammadi, Mahshid
Abstract:: A microchannel-based hemodialyzer offers a novel approach to hemodialysis practice and holds many promises for improving dialysis treatment efficiency and quality of life for kidney patients. The hollow fiber hemodialyzer, a conventional dialysis device, has certain limitations including non-uniformity of the dialysate flow path which necessitates the use of a...

Exploring experimental test stand design and operation within a system reliability research methodology

Creator:: Koopmans, Michael, 1986-
Abstract:: In cases where complex systems routinely experience extreme operating conditions, preventative maintenance is often employed to guard against system failure. Yet, with accessible real-time data and the standard practice becoming prohibitively expensive, the test stand can serve as a vital contributor to the development of system health and reliability estimations....

An investigation of multiphase flow in complex microchannel geometries for hemodialysis systems using residence time distribution analysis

Creator:: Coblyn, Matthew Y.
Abstract:: There are approximately 2.2 million cases of End-stage Renal Disease (ESRD) worldwide and current hemodialysis treatment is costly and ultimately insufficient compared to kidney transplantation. There is a strong need to arrive at a better solution for treating ESRD. Microchannel-based hemodialysis is one proposed option, already shown to have improved...
