Force Prediction in the Compression Sealing of an Ultra-thin Elastoviscoplastic Membrane

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...

Establishing Thermally-Enhanced Edge Registration (TEER) as a feasible alignment technique for metallic microlaminated devices

Creator:: Thomas, Joseph S.
Abstract:: The paper describes a Thermally-Enhanced Edge Registration (TEER) technique for precision aligning large numbers of laminae in diffusion bonding processes. This technique is particularly relevant for the formation of micro heat exchangers and microreactors requiring highly paralleled microchannel arrays but is also being used to register other laminated devices with...

Development of a passive micro-ball valve

Creator:: Wangwatcharakul, Worawut
Abstract:: A novel design, material, and fabrication method are presented to fabricate a passive micro-ball valve. Microvalves are critical components in microflow control devices used to control the fluid flows in microchannels. These microflow control devices can be integrated with microsensors to form micro analysis systems. Glass/silicon-based fabrication is complicated and...

Uniform residence time in microreactor-assisted solution deposition of CdS thin-films for CIGS photovoltaic cells

Creator:: Hires, Clayton Lamar
Abstract:: Photovoltaic (PV) cells have long been an attractive alternative for the consumption of fossil fuels but current manufacturing practices suffer from poor energy efficiency, large carbon footprints, low material utilization, high processing temperatures and high solvent usage. A critical step in PV production is the deposition of CdS as a...

Half Array Architecture for Advancing Microchannel Heat Recuperation to Market

Creator:: Brannon, Samuel T.
Abstract:: High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...

Development of an economical high temperature microchannel recuperator for solid oxide fuel cells

Creator:: Brannon, Samuel T.
Abstract:: To improve the performance of solid oxide fuel cells, a secondary power cycle can be driven by the recuperation of exhaust gas heat. Microchannel recuperators are attractive for waste heat recuperation due to compact form factors which also minimize the mass of the expensive superalloys required. This paper introduces a...

Foam-Core Meniscus Coating and Diffusion Bonding for Energy Applications

Creator:: Saranam, Venkata Rajesh
Abstract:: In the second chapter, a foam-core meniscus coating process was developed for retrofitting 100 nm-scale sol-gel anti-reflective coatings onto in-field solar panels through the deposition, evaporation, and curing of wet films.Advantages of this technique include the means to control fluid flow relative to substrate motion and the ability to conform...

Determining the dimensional requirements of a reliable compression sealing method for use in microchannel hemodialysers

Creator:: Ward, Dustin K.
Abstract:: Almost 600,000 people in the United States were treated for End Stage Renal Disease in 2010. A majority of those people received hemodialysis from central medical facilities. It has been reported a better treatment option for these patients would be realized if the patients had more frequent hemodialysis treatments. A...

Nickel nanoparticles-assisted diffusion brazing of stainless steel 316 for microfluidic applications

Creator:: Tiwari, Santosh K.
Abstract:: Transient liquid-phase diffusion brazing is used in precision, hermetic joining applications as a replacement for diffusion bonding to reduce cycle times, reduce bonding pressure and improve yields. Studies showed that the interlayer used in diffusion brazing can be detrimental due to the use of melting point depressants (MPDs). The goal...
