Electroosmotic flow in single PDMS nanochannels
(Royal Society of Chemistry, 2016-05-23)The electroosmotic flow (EOF) velocity in single PDMS nanochannels with dimensions as small as 20 nm is investigated systematically by the current slope method in this paper. A novel method for the fabrication of single ... -
Electroosmotic flow velocity in DNA modified nanochannels
(Elsevier, 2019-10-01)Electroosmotic flow (EOF) is systematically investigated in DNA grafted hard PDMS (h-PDMS) channels with size ranging from 50 nm to 2.5 μm by using the current-slope method. The effects of the DNA types, the incubation ... -
Electrophilic ‘Umpolung’ Cyclizations of Alkynes in the Synthesis of Polycyclic Aromatic Hydrocarbons
(University of Waterloo, 2021-05-12)Polycyclic aromatic hydrocarbons (PAHs), such as acenes and phenacenes, are important structural motifs which have found great utility in the future of electronics as organic semi-conducting materials. Reliable methods of ... -
Electrophysiological indices of information processing in psychopathy
(University of Waterloo, 2009-01-21)Psychopathy is a severe personality disorder associated with a range of affective, interpersonal, and behavioural abnormalities. Evidence suggests that psychopaths show marked deficits in processing emotional information, ... -
Electrophysiological measures of optic nerve function
(University of Waterloo, 2021-08-26)The contribution of retinal ganglion cells (RGCs) to human electroretinograms (ERGs) is known, but that of chicken (Gallus gallus domesticus) is not clear. This project seeks to determine the effect of RGC dysfunction on ... -

Electrospark Deposited Interlayer and its Influence on Dissimilar Resistance Welding of DP600 to AA5052
(University of Waterloo, 2021-09-22)Challenges associated with the resistance spot welding of aluminum and steel must be addressed to enable wider use of low-density aluminum alloys in commercial vehicles. These challenges include the significant difference ... -
Electrostatic Bifurcation In-Plane Sensors
(University of Waterloo, 2022-01-24)Electrostatic MEMS sensors are known for their high sensitivity, wide range of operation, and quick response. These unique attributes give Electrostatic MEMS sensors an edge over other MEMS transduction mechanisms ... -
Electrostatic discharge protection circuit for high-speed mixed-signal circuits
(University of Waterloo, 2007-05-10)ESD, the discharge of electrostatically generated charges into an IC, is one of the most important reliability problems for ultra-scaled devices. This electrostatic charge can generate voltages of up to tens of kilovolts. ... -
Electrostatic Discharge Protection Devices for CMOS I/O Ports
(University of Waterloo, 2012-08-30)In modern integrated circuits, electrostatic discharge (ESD) is a major problem that influences the reliability of operation, yield and cost of fabrication. ESD discharge events can generate static voltages beyond a few ... -
Electrostatic Interactions of Peptides with Lipid Membranes: Competitive Binding between Cationic Peptides and Divalent Counterions
(University of Waterloo, 2010-09-30)In this thesis, we investigate a variety of problems involving the interaction of cationic peptides with lipid membranes. To this end we adopt Poisson-Boltzmann (PB) theory and coarse-grained models of these molecules. We ... -
Electrostatic MEMS Bifurcation Sensors
(University of Waterloo, 2018-08-24)We report experimental evidence of a new instability in electrostatic sensors, dubbed quasi-static pull-in, in two types of micro-sensors operating in ambient air. We find that the underlying mechanism and features of this ... -
Electrostatic Micro-Tweezers
(University of Waterloo, 2020-06-25)This dissertation presents a novel electrostatic micro-tweezers designed to manipulate particles with diameters in the range of 5-14 μm. The tweezers consist of two grip-arms mounted to an electrostatically actuated initially ... -
Electrostatic Modification of Phospholipid and Lipopolysaccharide Membranes
(University of Waterloo, 2012-05-23)Biological membranes are quasi two-dimensional self-assembled structure, primarily serving as a barrier to the leakage of cell’s contents. The main constituents of biological membrane are various amphiphilic lipids that ... -
The electrostatic potential in a finite ionic crystal
(University of Waterloo, 1972-11-01)This thesis is written in two parts. In Part One, we develop a new method for evaluating three dimensional lattice summations and apply it to the evaluation of the electrostatic potential of a finite ionic crystal. We then ... -
Electrostatically Directed Visual Fluorescence Response of DNA-Functionalized Monolithic Hydrogels for Highly Sensitive Hg2+ Detection
