Spring 2010
The procedure for milling micrometre scale cantilevers of lutetium iron garnet using a focused ion beam microscope was developed. The infrastructure to study these cantilevers using rotational hysteresis loops and ferromagnetic resonance experiments was set up. The cantilevers were shown to...

Nanophotonic detection of nanomechanical structures for use toward mass sensing applications
DownloadSpring 2014
Nanomechanical beam resonators show much promise for use in integrated on-chip mass sensing systems. This follows from their own very small masses and also their ability to store the mechanical energy of their oscillations to produce strong measurable mechanical response signals. To achieve...

Quantum Chemical Investigations of Structural and Photophysical Properties of Emissive RNA Nucleobase Analogues
DownloadFall 2017
The photostability of nucleic acid constituents is crucial in maintaining the integrity of our genetic code. This is achieved by the essential mechanism of ultrafast radiationless decay of the singlet excited state to the electronic ground state of nucleobases. While this mechanism provides...

The extent of glycation and conformational changes of horse myoglobin (Mb) upon glycation with N-acetyl-glucosamine (GlcNAc), glucose (Glc) and glucosamine (GlcN) were investigated. Among tested sugars, the rate of glycation with GlcN was the most rapid as shown by MALDI and ESI mass...

Terbium fluorescence as a sensitive, inexpensive probe for UV-induced damage in nucleic acids
Download2013-01-01
El-Yazbi, Amira F., Loppnow, Glen R.
Much effort has been focused on developing methods for detecting damaged nucleic acids. However, almost all of the proposed methods consist of multi-step procedures, are limited, require expensive instruments, or suffer from a high level of interferences. In this paper, we present a novel simple,...

Total Internal Reflection Fluorescence Microscopy to Study Bitumen and Clay Interaction in Oil Sands Tailings
DownloadFall 2016
Oil sands tailings management remains to be a major challenge for oil industry in Canada. Promoting quick settling of fines in tailings ponds is the key to its treatment. Bitumen lost to tailings during oil sands extraction is also believed to hinder settling and consolidation of clays in...
