Exploring the thermal stability of DNA-linked gold nanoparticles in ionic liquids and molecular solvents
(Royal Society of Chemistry, 2012-11-01)While water is the most commonly used solvent for DNA, many co-solvents have been added for various applications. Ionic liquids (ILs) are molten salts at around room temperature. ILs have been tested as a green solvent for ... -
Extended Latanoprost Release from Commercial Contact Lenses: In Vitro Studies Using Corneal Models
(Public Library of Science, 2014-10-09)In this study, we compared, for the first time, the release of a 432 kDa prostaglandin analogue drug, Latanoprost, from commercially available contact lenses using in vitro models with corneal epithelial cells. Conventional ... -
Extension of geopolitical supply risk methodology: Characterization model applied to conventional and electric vehicles
(Elsevier, 2017-09-20)The diversity of materials employed in modern products and the complexity of globalized supply chains raise the importance of assessing supply risk of commodity inputs to product systems. Therefore, this article extends ... -
Extensive marine anoxia during the terminal Ediacaran Period
(American Association for the Advancement of Science, 2018-06-20)The terminal Ediacaran Period witnessed the decline of the Ediacara biota (which may have included many stemgroup animals). To test whether oceanic anoxia might have played a role in this evolutionary event, we measured U ... -
Extracellular dsRNA induces a type I interferon response mediated via class A scavenger receptors in a novel Chinook salmon derived spleen cell line
(Elsevier, 2018-12-01)Despite increased global interest in Chinook salmon aquaculture, little is known of their viral immune defenses. This study describes the establishment and characterization of a continuous cell line derived from Chinook ... -
Extracting Counterexamples from Transitive-Closure-Based Model Checking
(IEEE, 2019)We address the problem of how to extract counterexamples for the transitive-closure-based model checking (TCMC) technique. TCMC is a representation of the CTLFC (CTL with fairness constraints) model checking problem in ... -
Extraction of DNA staining dyes from DNA using hydrophobic ionic liquids
(Royal Society of Chemistry, 2013-05-18)The partition of oligonucleotides and DNA staining dyes into a few hydrophobic ionic liquids has been studied, where the oligonucleotides remain in the aqueous phase and all the DNA staining dyes are extracted in the ionic ... -
Extraction of Oil from Oil Sands Using Thermoresponsive Polymeric Surfactants
(American Chemical Society, 2015-03-18)Several thermoresponsive block copolymers constituted of a poly(ethylene glycol) (PEG) and a poly(2-(2-methoxyethoxy) ethyl methacrylate) (PMEO(2)MA) block were prepared by atom transfer radical polymerization (ATRP) and ... -
Extrudable hydroxyapatite/plant oil-based biopolymer nanocomposites for biomedical applications: Mechanical testing and modeling
(Elsevier, 2019-07-15)Towards developing bone-inspired, high performance composite biomaterials, two nanocomposite inks, consisting of a plant oil-based biopolymer resin (soybean oil epoxidized acrylate (SOEA)) and silanized nano-hydroxyapatite ... -
Eye gaze and head orientation modulate the inhibition of return for faces
(Springer, 2015-11-01)The present study used an inhibition of return (IOR) spatial cueing paradigm to examine how gaze direction and head orientation modulate attention capture for human faces. Target response time (RT) was measured after the ... -
« Échos » et « brèches » dans la poésie de Louis-Jean Thibault
(Département de français de l'Université d'Ottawa, 2011)Résumé Autour de la décennie 1960, toute une génération de poètes prêtait sa voix au pays à venir. Mais faute de pays réel, clairement défini, cette poésie était confinée à l’abstraction, évoquant « l’âme » d’un ineffable ... -
Fabrication and electrokinetic motion of electrically anisotropic Janus droplets in microchannels
(Wiley, 2016-09-07)This paper presents experimental investigations of the fabrication and the motion of electrically anisotropic Janus droplets in a microchannel under externally applied direct current (DC) electrical field. The fabrication ... -
Fabrication of nanochannels on polystyrene surfaces
(Biomicrofluidics, 2015-05)Solvent-induced nanocrack formation on polystyrene surface is investigated experimentally. Solubility parameter and diffusion coefficient of alcohols are employed to elucidate the swelling and cracking processes as well ... -
Fabrication of polydimethylsiloxane (PDMS) nanofluidic chips with controllable channel size and spacing
(Royal Society of Chemistry, 2016-08-09)The ability to create reproducible and inexpensive nanofluidic chips is essential to the fundamental research and applications of nanofluidics. This paper presents a novel and cost-effective method for fabricating a single ... -
