Fast Molecular Beacon Hybridization in Organic Solvents with Improved Target Specificity
(American Chemical Society, 2010-12-02)DNA hybridization is of tremendous importance in biology, bionanotechnology, and biophysics. Molecular beacons are engineered DNA hairpins with a fluorophore and a quencher labeled on each of the two ends. A target DNA can ... -
Fast pH-assisted functionalization of silver nanoparticles with monothiolated DNA
(Royal Society of Chemistry, 2012-10-18)Attaching monothiolated DNA to silver nanoparticles has been achieved at pH 3.0 in 30 minutes and difficulties associated with DNA attachment to AgNPs at neutral pH have been revealed by studying DNA adsorption kinetics. -
Fast quantitation of opioid isomers in human plasma by differential mobility spectrometry/mass spectrometry via SPME/open-port probe sampling interface
(Elsevier, 2017-10-23)Mass spectrometry (MS) based quantitative approaches typically require a thorough sample clean-up and a decent chromatographic step in order to achieve needed figures of merit. However, in most cases, such processes are ... -
Fast Quantitation of Target Analytes in Small Volumes of Complex Samples by Matrix-Compatible Solid-Phase Microextraction Devices
(Wiley, 2017-06-20)Herein we report the development of solid-phase microextraction (SPME) devices designed to perform fast extraction/enrichment of target analytes present in small volumes of complex matrices (i.e. V <= 10 mu L). Micro-sampling ... -
Fast Stochastic Global Optimization Methods and Their Applications to Cluster Crystallization and Protein Folding
(University of Waterloo, 2005)Two global optimization methods are proposed in this thesis. They are the multicanonical basin hopping (MUBH) method and the basin paving (BP) method. <br /><br /> The MUBH method combines the basin hopping (BH) ... -
Fast Switchable Ultrastrong Coupling Between Superconducting Artificial Atoms and Electromagnetic Fields
(University of Waterloo, 2019-08-23)This thesis consists of two parts: the main part is a theoretical investigation of the ultrastrong coupling regime for atom-light coupling in superconducting circuits, and the second part is concerned with the development ... -
Fate and Transport of Land Applied Waste Greenhouse Feed Water During Field Infiltration Experiments
(University of Waterloo, 2016-04-29)Because of the high concentration of greenhouses in Essex County, greenhouse feed water discharges are considered as a potential contributor to nuisance and harmful algal blooms and hypoxia in western Lake Erie. Waste ... -
Fate and Transport of Naphthenic Acids in Glacial Aquifers
(University of Waterloo, 2004)Naphthenic acids (NAs) are carboxylated alkanes and cycloalkanes concentrated in wastewater during oil sands processing. The general chemical formula is C{n}H{n+Z}O{2}, where n represents the number of carbon atoms and ... -
Fate and Transport of Synthetic DNA in Surface Water
(University of Waterloo, 2021-09-29)Unlike conventional salt or dye tracers, artificial/synthetic DNA hydrologic tracers are essentially non-toxic and several can be used simultaneously. These features have implications for DNA to be used to better understand ... -
Fate of Adsorbed U(VI) during Sulfidization of Lepidocrocite and Hematite
(American Chemical Society, 2017-02-21)The impact on U(VI) adsorbed to lepidocrocite (gamma-FeOOH) and hematite (alpha-Fe2O3) was assessed when exposed to aqueous sulfide (S(II)(aq)) at pH 8.0. With both minerals, competition between S(-II) and U(VI) for surface ... -
Fate of Chlorinated Compounds in a Sedimentary Fractured Rock Aquifer in South Central Wisconsin
(University of Waterloo, 2008-10-22)A study was carried out in a sedimentary fractured rock site located in south central Wisconsin, US, which was impacted by DNAPL releases estimated to occur in the 1950’s and 1960’s. The majority of the DNAPL has accumulated ... -
Fatigue related impairments in oculomotor control are prevented by caffeine
(Nature, 2016-05-25)Strenuous exercise can result in an inability of the central nervous system to drive skeletal muscle effectively, a phenomenon known as central fatigue. The impact of central fatigue on the oculomotor system is currently ... -
Feasibility of Injecting Large Volumes of CO2 into Aquifers
(Elsevier, 2009-02)Although it is recognized that deep aquifers offer a very large potential storage capacity for CO2 sequestration it is not clear how to fill the storage with a large volume of CO2 in a relatively short period of time. The ... -
Feasibility of Testing the Event Formalism with Refractive Materials
(University of Waterloo, 2022-05-20)In this thesis, we evaluate the feasibility of verifying the effect of gravity on the quantum entanglement by simulating gravity’s effects with other physical systems. Specifically, we work in the framework of the Event ... -
