Characterization of Langmuir-Blodgett Films by Electron Spin Resonance Spectroscopy
(University of Waterloo, 2020-01-15)Langmuir-Blodgett (LB) films built up with amphiphilic molecules have well-known optical, electrical and magnetic properties. For most applications, it is fundamentally important to understand the structure of the films. ... -
Geophysical response to simulated methane migration in groundwater based on a controlled injection experiment in a sandy unconfined aquifer
(Elsevier, 2019-09)Geophysical methods have the capacity to detect and characterize gas-phase dynamics in groundwater. Suitable methods can be deployed at surface or within boreholes depending on the required depth of investigation, ... -
Methane gas transport in unconfined aquifers: A numerical sensitivity study of a controlled release experiment at CFB Borden
(Elsevier, 2019-08)Subsurface leakage of natural gas from petroleum wells can impact freshwater aquifers. Accurate prediction of gas migration in the subsurface will depend on knowledge of permeability, porosity, and flow system conditions. ... -
Efficient polyyne formation by ns and fs laser-induced breakdown in ethylene and acetylene gas flow
(Elsevier, 2019-11)We studied polyyne formation by gas phase laser-induced breakdown in ethylene and acetylene gas flow using ns and fs lasers. The results show that acetylene is the most efficient target molecule for generating polyynes ... -
Development and characterization of a laminar aerosol flow tube
(AIP, 2006-03)We have developed a new laminar aerosol flow tube (AFT) to study transformations such as ice nucleation, deliquescence, and efflorescence in model atmospheric aerosols. The apparatus consists of four sections which can be ... -
Causal Discovery of Photonic Bell Experiments
(University of Waterloo, 2020-01-13)A causal understanding of a physical theory is vital. They provide profound insights into the implications of the theory and contain the information required to manipulate, not only predict, our surroundings. Unfortunately, ... -
Application of Biochar to Stabilize Mercury in Riverbank Sediments and Floodplain Soils from South River, VA under Conditions Relevant to Riverine Environments
(University of Waterloo, 2020-01-07)Disposal of mercury (Hg) containing products related to industrial activities has led to large-scale watershed contamination across the globe, posing long-term risks to human health due to its persistent properties. Hg in ... -
Application of matrix compatible solid phase microextraction (SPME) coatings for the analysis in complex food matrices
(University of Waterloo, 2020-01-06)In recent years, studies regarding food analysis have increased due to the globalization of food trade as well as concerns about the safety and traceability of food commodities. In this regard, the field of food analysis ... -
Transport of chloride and deuterated water in peat: The role of anion exclusion, diffusion, and anion adsorption in a dual porosity organic media
(Elsevier, 2019-08)The dual-porosity structure of peat and the extremely high organic matter content give rise to a complex medium that typically generates prolonged tailing and early 50% concentration breakthrough in the breakthrough curves ... -
Introducing a mechanically robust SPME sampler for the on-site sampling and extraction of a wide range of untargeted pollutants in environmental waters
(Elsevier, 2019-09)The present study introduces a mechanically robust, sealable SPME sampler for the on-site sampling and extraction of a wide range of untargeted pollutants in environmental waters. Spray-coating and dip coating methodologies ... -
Direct coupling of solid phase microextraction with electrospray ionization mass spectrometry: A Case study for detection of ketamine in urine
(Elsevier, 2019-10-10)Electrospray ionization mass spectrometry (ESI-MS) is a commonly used technique for analysis of various samples. Solid phase microextraction (SPME) is a simple and efficient technique that combines both sampling and sample ... -
Development and validation of a fully automated solid phase microextraction high throughput method for quantitative analysis of multiresidue veterinary drugs in chicken tissue
(Elsevier, 2019-05-16)This paper presents the development and validation of a fully automated, high-throughput multiclass, multiresidue method for quantitative analysis of 77 veterinary drugs in chicken muscle via direct immersion solid phase ... -
Structure/reaction directed analysis for LC-MS based untargeted analysis
(Elsevier, 2019-03-07)In LC-MS based untargeted analysis, data is collected at the peak or ion level, although the investigated biochemistry processes occur at the compound or reaction level. To this end, the presence of redundancy peaks such ... -
Pharmacy patron perspectives of community pharmacist administered influenza vaccinations
(Elsevier, 2019-02)One approach to boost influenza vaccination coverage has been to expand immunization authority. In 2012, the province of Ontario gave community pharmacists the authority to administer the influenza vaccine. -
The blood compatibility challenge. Part 3: Material associated activation of blood cascades and cells
(Elsevier, 2019-08)Following protein adsorption/activation which is the first step after the contact of material surfaces and whole blood (part 2), fibrinogen is converted to fibrin and platelets become activated and assembled in the form ... -
Removal of pharmaceutical compounds, artificial sweeteners, and perfluoroalkyl substances from water using a passive treatment system containing zero-valent iron and biochar
(Elsevier, 2019-11-15)Emerging contaminants are widely detected and persistent in environmental waters. Advanced oxidation processes are among the most effective methods for removing emerging contaminants from water; however, high energy ... -
