Iron oxide nanozyme catalyzed synthesis of fluorescent polydopamine for light-up Zn2+ detection
(Royal Society of Chemistry, 2016-07-29)Fluorescent polydopamine (FPD) is an interesting material with excellent biocompatibility. However, its preparation is currently a lengthy and potentially dangerous process. We herein employ magnetic iron oxide (Fe3O4) ... -
Manipulation of electronic band structure by doping colloidal gallium oxide nanocrystals and its impact on photocatalysis
(University of Waterloo, 2018-01-23)Semiconductor photocatalyst have been of interest due to its robust nature, non-selectivity, low toxicity, and high tunability. Its various applications such as water splitting, water purification, anti-microbial, etc make ... -
Modulating Optical and Photocatalytic Properties of Transparent Metal Oxide Nanostructures via Defect Engineering
(University of Waterloo, 2018-01-15)The chemistry of nanostructure has increasingly drawn attention as a compelling branch of semiconductor research. Billions of dollars are annually spent to intentionally incorporate dopants into nanomaterials to enhance ... -
Parallel Polyadenine Duplex Formation at Low pH Facilitates DNA Conjugation onto Gold Nanoparticles
(American Chemical Society, 2016-11-15)DNA-functionalized gold nanoparticles (AuNPs) have been extensively used in sensing, drug delivery, and materials science. A key step is to attach DNA to AuNPs, forming a stable and functional conjugate. Although the ... -
Properties of Carbon Nanomaterials Produced by Ultrashort Pulsed Laser Irradiation
(University of Waterloo, 2012-08-29)Two synthesis pathways were employed throughout this work to create a variety of unique carbon materials. The first of these routes involves the photo-dissociation of liquids by direct irradiation with ultrashort laser ... -
Silicon-based Materials as Negative Electrodes for Li-ion Batteries
(University of Waterloo, 2014-05-02)Silicon is a promising negative electrode material for lithium-ion (Li-ion) batteries, with volumetric and gravimetric capacities much higher than those in current commercial batteries. Implementation of Si as a negative ... -
Synthesis, Electrochemistry and Solid-Solution Behaviour of Energy Storage Materials Based on Natural Minerals
(University of Waterloo, 2013-04-15)Polyanionic compounds have been heavily investigated as possible electrode materials in lithium- and sodium-ion batteries. Chief among these is lithium iron phosphate (LiFePO4) which adopts the olivine structure and has ...
