Title: Forward Heating in Wind-driven Flames

Date: Friday, July 14, 2017

Time: 2:00 PM – 4:00 PM

Location: FPE Conference Room, 3106 J.M. Patterson Building

 

List of committee members:
Prof. Michael J. Gollner, Chair
Prof. Arnaud Trouve
Prof. Andre Marshall
Prof. Elaine Oran
Prof. Peter Sunderland

 

Abstract: Wildland fires pose a significant threat to the environment and society at large. While steps have been taken to predict their behavior, the large amount of unknowns and the intermittent nature of the fire itself makes predictions much harder than those typically encountered with the built environment, especially under the influence of wind. It’s well known that the spread rate of a fire depends largely on forward heating from the flame to unburnt fuels. In wildland fires, the intermittent nature of fame is thought to be important to the flame spread process. In this work, both the averaged and time-dependent aspects of the flame will be studied, including the total heat flux distribution on the downstream surface, flame extension and attachment, and flame pulsation frequencies. Correlations of these properties, dependent on both fire size and ambient wind will provide a means to describe the fuel heating and ignition processes in wildland fires.

Title: THERMOPLASTIC MICROFLUIDIC PCR TECHNOLOGIES FOR NEAR PATIENT DIAGNOSTICS

Date: Thursday, June 15

Time: 2:00 PM

Location: DeWALT seminar room (Glenn L. Martin Hall)

Committee:
Dr. Don DeVoe – Chair
Dr. Miao Yu
Dr Benjamin Shapiro
Dr. Sarah Bergbreiter

Dr. Ian White – Dean’s Representative

Abstract:Microfluidic technologies have great potential to help create portable, scalable, and cost-effective devices for rapid polymerase chain reaction (PCR) diagnostics in near patient settings. Unfortunately, current PCR diagnostics have not reached ubiquitous use in such settings because of instrumentation requirements, operational complexity, and high cost. This dissertation demonstrates a novel platform that can provide reduced assay time, simple workflow, scalability, and integration in order to better meet these challenges. First, a disposable microfluidic chip with integrated Au thin film heating and sensing elements is described herein. The system employs capillary pumping for automated loading of sample into the reaction chamber, combined with an integrated hydrophilic valve for precise self-metering of sample volumes into the device. With extensive multiphysics modeling and empirical testing we were able to optimize the system and achieve cycle times of 14 seconds and completed 35 PCR cycles plus HRMA in a total of 15 minutes, for successful identification of a mutation in the G6PC gene indicative of von Gierke’s disease.

Next, a scalable sample digitization method that exploits the controlled pinning of fluid at geometric discontinuities within an array of staggered microfluidic traps is described. A simple geometric model is developed to predict the impact of device geometry on sample filling and discretization, and validated experimentally using fabricated cyclic olefin polymer devices.

Finally, a 768-element staggered trap array is demonstrated, with highly reliable passive loading and discretization achieved within 5 min. Finally, a technique for reagent integration by pin spotting affords simplified workflow, and the ability to perform multiplexed PCR. Reagent printing formulations were optimized for stability and volume consistency during spotting. Paraffin wax was demonstrated as a protective layer to prevent rehydration and reagent cross contamination during sample loading. Deposition was accomplished by a custom pin spotting tool. A staggered trap array device with integrated reagents successfully amplified and validated a 2-plex assay, showing the potential of the platform for a multiplexed antibiotic resistance screening panel.
