Crystallization Studies of Highly Monodisperse Oligomeric Poly(Ethylene Oxide)
(University of Waterloo, 2018-12-13)Poly(ethylene oxide) is one of the most intensively studied polymers in terms of crystallization, because of its linear structure. In this thesis the chapters are organized in a self-contained fashion, with a general ... -
Hydrobiogeophysics: Linking geo-electrical properties and biogeochemical processes in shallow subsurface environments
(University of Waterloo, 2018-12-13)Microbially mediated reactions drive (bio)geochemical cycling of nutrients and contaminants in shallow subsurface environments. Environmental forcings exert a strong control on the timing of reactions and the spatial ... -
Photocatalytic performances of ZnO nanoparticle film and vertically aligned nanorods in chamber-based microfluidic reactors: Reaction kinetics and flow effects
(Elsevier BV, 2017-07-15)The nanoparticle seed layer (a film) and vertically aligned nanorods of zinc oxide (ZnO) with different lengths were fabricated within a novel chamber-based microfluidic (microchamber) reactor with a varying height of ... -
Hydrodynamic shrinkage of liquid CO2 Taylor drops in a straight microchannel
(IOP Publishing, 2018-02-12)Hydrodynamic shrinkage of liquid CO2 drops in water under a Taylor flow regime is studied using a straight microchannel (length/width similar to 100). A general form of a mathematical model of the solvent-side mass transfer ... -
Numerical Study on Single Flowing Liquid and Supercritical CO2 Drop in Microchannel: Thin Film, Flow Fields, and Interfacial Profile
(MDPI, 2018-06-01)Taylor segments, as a common feature in two- or multi-phase microflows, are a strong flow pattern candidate for applications when enhanced heat or mass transfer is particularly considered. A thin film that separates these ... -
Droplet Microfluidic System with On-Demand Trapping and Releasing of Droplet for Drug Screening Applications
(American Chemical Society (ACS), 2017-01-03)96-Well plate has been the traditional method used for screening drug compounds libraries for potential bioactivity. Although this method has been proven successful in testing doseÐresponse analysis, the microliter consumption ... -
On nonequilibrium shrinkage of supercritical CO2 droplets in a water-carrier microflow
(AIP Publishing, 2018-07-16)We report an experimental study on the hydrodynamic shrinkage of supercritical carbon dioxide (scCO(2)) microdroplets during a nonequilibrium process. After scCO(2 )microdroplets are generated by water shearing upon a ... -
Detection of Nitroaromatic Compounds through Fluorescence Quenching of Pyrene Labeled Starch Nanoparticles
