Laser-Induced Fluorescence Studies of Molecular Dynamics
The vibronic rovibronic fluoresence excitation spectra of biacetyl, methylglyoxal, and pentanedione have been recorded for the excited singlet state of each molecule. In particular, the fluorescence of biacetyl in a molecular beam has been shown to exhibit the quantum beat effect in the …

The evaluation of a low powered microwave induced plasma as an atom cell for atomic spectrometry
… evaluated are atomic emission and atomic fluoresence. Analytical merits of the microwave induced plasma using detection limits and studies of interelement effects (i.e. vaporization, ionizationâ and scatter interferences) are also presented.

Construction of a quantum gas microscope for fermionic atoms
… lattice, with the imaging optics collecting the fluoresence light for high-resolution imaging. With molasses cooling set up, single-site fluoresence imaging of bosons and fermions in the same experimental apparatus is within reach.

Aspects of the chemistry of some stony meteorites
… Al, Mg, Na, K, Sr, Zr, Y, Ba and Ni) using X-ray fluoresence analysis. A fusion technique was used to determine the more abundant elements, while trace constituents were determined on powdered samples. The data obtained have been critically examined from the point of view of both precision and …

Determining The Excited State Properties of Novel Aryleneethynylenes
… absorption and fluorescence spectroscopy and fluoresence quantum yields and lifetime). Ab initio calculations have afforded opti- mised geometries which have been compared to molecular structures determined us- ing X–ray diffraction and vibrational spectroscopy. TD–DFT calculations have been …

Genetic and biochemical analysis of materials from a medieval population from Ynys Mon North Wales
… GPI, a novel technique called Qualitative Light Fluoresence (QLF), based on autofluoresence, was used to ascertain the surface condition of the teeth. Compared to the fluorescence of modern enamel, there was a net loss of 21.8% fluorescence, although the degree of fluorescence from one sample to …

Dissolved organic material in groundwater and application of fluorescence spectroscopy coupled with EEM PARAFAC models as a means of site characterisation
The role of dissolved organic matter (DOM) in aquatic systems has been associated with numerous physiochemical processes including carbon sink, contamination indicator and important component in natural geochemical and microbial processes. However, to date research into the behaviour of DOM within …

PLUMAGE CHARACTERISTICS OF THE LONG-EARED OWL (Asio otus) IN THE VISIBLE AND ULTRAVIOLET SPECTRA OF LIGHT
<p>The study of plumage is a foundational aspect of ornithology, and the features of even a single feather can provide valuable information on an individual’s health, sex, or age. Recent discoveries on the abilities of birds to see in the ultraviolet (UV) spectrum has led to study of the …

Illuminating the relationship between flagellar activity and bacterial swimming
Bacterial swimming and chemotaxis serves as a model system for understanding information processing in living organisms. My thesis project was focused on studying the swimming behavior of Escherchia coli bacterial cells. These cells swim by rotating helical filaments called flagella. An individual …

Selection of a Non-Phosphorylated Peptide Inhibitor of BRCA1’s (BRCT)2 Domain
A growing body of literature suggests Breast Cancer-Associated Protein 1 (BRCA1) is important not only as a cause, but also as a target in the quest for cancer treatment. BRCA1 deficient cells treated with radiation as well as PARP inhibitors and other chemotherapeutics demonstrate a greater …

Biochemical and Structural Studies of Amyloid Proteins
Amyloidogenic neurodegenerative disorders such as Alzheimer’s disease (AD) and Parkinson’s disease (PD) are an important health issue. However, the underlying molecular mechanisms of the disease-related protein aggregates, that are present in humans, are only understood partially. I have used and …
