Placing Limits on Light Axions with EHT Polarimetry via Closure Traces
(University of Waterloo, 2023-08-31)Black holes can amplify incoming bosonic waves via rotational superradiance, inducing bound states of ultralight bosons around them. This phenomenon has the potential to confine the parameter spaces of new bosons. Axions, ... -
Plankton Metabolic Balance and its Controlling Factors in the Coastal Zone of the Laurentian Great Lakes
(University of Waterloo, 2007-10-01)Plankton metabolic balance (PMBm) of the surface mixed layer was calculated as the ratio of areal rates of gross photosynthesis (AGP) to community respiration (AR), and estimated for four Laurentian Great Lakes coastal ... -
Plant Growth-Promoting Bacterial Endophytes that contain ACC Deaminase: Isolation, Characterization, and Use
(University of Waterloo, 2013-04-26)Bacteria that provide benefit to plants are considered to be plant growth-promoting bacteria (PGPB) and can facilitate plant growth by a number of different mechanisms. Plant growth-promoting bacteria that are able to ... -
Plant Growth-Promoting Rhizobacteria (PGPR) Enhanced Phytoremediation of DDT Contaminated Soil
(University of Waterloo, 2008-05-21)Although the pesticide DDT has been banned from use in Canada for more than three decades, DDT still persists in Canadian farmlands at detectable levels. Much effort, such as incineration, thermal desorption, and bioremediation, ... -
Plant growth-promoting root-colonizing bacterial endophytes
(Elsevier, 2021-12)The development of an environmentally friendly agricultural system as opposed to conventional methods using chemical fertilizers and pesticides for improved crop productivity is a promising aspect of modern agricultural ... -
Plant-Growth Promoting Rhizobacteria Enhanced Phytoremediation of Saline Soils and Salt Uptake into Plant Biomass
(University of Waterloo, 2011-07-19)Soil salinity affects an estimated one billion hectares worldwide. Excess salinity inhibits plant growth, limiting crop production. This is caused by osmotic stress in saline soil, nutrient imbalance and specific ion ... -
Plasmon Induced Carrier Polarization in Semiconductor Nanocrystals
(University of Waterloo, 2020-01-24)Currently used technologies are reaching the natural performance limit, invigorating the development of different quantum technologies. Spintronics and valleytronics are emerging quantum electronic technologies that rely ... -
Plasmonic and Magneto-Optical Properties of Nonstoichiometric Indium Nitride Nanostructures
(University of Waterloo, 2019-10-23)Localized surface plasmon resonance (LSPR) in semiconductor nanostructures have attracted intense attention recently for its broad application in bio-imaging, chemical sensing, photocatalysis, and photovoltaics. Compared ... -
Plastic debris in the Laurentian Great Lakes: A review
(Elsevier, 2015-03-01)Pollution by plastic debris is an increasing environmental concern in the Laurentian Great Lakes where it affects open-water, shoreline, and benthic environments. Open-water surveys reveal that in certain areas of the Great ... -
Plastic debris in the Laurentian Great Lakes: Classification, distribution and environmental drivers
(University of Waterloo, 2015-07-03)Pollution by plastic debris is an increasing environmental concern in the Laurentian Great Lakes: it affects open-water, shoreline, and benthic environments. Many plastics degrade slowly in the environment and may have ... -
Platinated DNA oligonucleotides: new probes forming ultrastable conjugates with graphene oxide
(Royal Society of Chemistry, 2014-06-21)Metal containing polymers have expanded the property of polymers by involving covalently associated metal complexes. DNA is a special block copolymer. While metal ions are known to influence DNA, little is explored on its ... -
A platinum shell for ultraslow ligand exchange: unmodified DNA adsorbing more stably on platinum than thiol and dithiol on gold
(Royal Society of Chemistry, 2015-08-04)Due to the ultraslow ligand exchange rate on Pt, non-thiolated DNA is adsorbed on platinum nanoparticles (PtNPs) more stably than thiolated and even dithiolated DNA on AuNPs. Adsorption kinetics, capacity and stability are ... -
Pluronic-Based Nanoparticles for Gene Therapy Applications
(University of Waterloo, 2014-01-24)Non-viral delivery vectors have potential advantages over the viral systems that currently are used extensively for delivering therapeutic genes of interest. However, non-viral gene therapy has low efficiencies in vivo, ... -
A Polar Decomposition for Quantum Channels: Theory and Applications
(University of Waterloo, 2019-08-23)Every potential benefit of quantum computers would be lost without methods to protect the computations from error. Quantum channels provide a framework for understanding error in quantum systems. In general, for a system ... -
Polarimetric and birefringence analysis of presumed amyloid-beta deposits in the retina in association with Alzheimer's disease
(University of Waterloo, 2018-09-26)Alzheimer's disease is a neurodegenerative disease which leads to symptoms such as loss of memory and other neurological dysfunctions, ultimately leading to death. Two key hallmarks of Alzheimer's disease are abnormally ... -
Polarity Control for Nonthiolated DNA Adsorption onto Gold Nanoparticles
(American Chemical Society, 2013-05-21)Gold nanoparticles (AuNPs) functionalized with thiolated DNA have enabled many studies in nanoscience. The strong thiol/gold affinity and the nanoscale curvature of AuNPs allow the attached DNA to adapt an upright conformation ... -
