The Knudsen pump works on the principle of thermal transpiration. As a result of requiring a thermal gradient, channel hydraulic diameter smaller than the mean free path of the gas being pumped, and having no moving parts, the Knudsen pump features...
Gold nanoparticles (AuNPs) have attracted enormous attention in the field of nanotechnology for applications such as, immunoassay, drug delivery, contrast enhancement and tumor therapy. The typical range of gold nanoparticles varies from 1– 150...
Nuclear magnetic resonance spectroscopy; Spectrum analysis--Data processing
Since its development, nuclear magnetic resonance (NMR) has become one of the primary methods of chemists for structure elucidation, which is the determination of a compound's molecular structure. Current software packages enable scientists to...
The acetogenin annonacin, from the tropical annonaceous plant Annona muricata, is a lipophilic, mitochondrial complex I inhibitor reported to be more toxic than rotenone to mesencephalic neurons. The temperate annonaceous plant Asimina tri/oba...
Hyaluronan (HA) is a major structural component of the ocular vitreous humor
(VH) and lipids are essential building blocks of cell membranes. However, little is known
about their possible interactions. The VH is known to undergo liquefaction...
Human exposure to mercury has been shown to cause a number of adverse health outcomes, predominantly neurological effects. The developing fetus is most susceptible, and even low levels of exposure have been shown to produce nervous system deficits....
The discovery of carbon nanotubes and subsequently graphene has led to an interest in carbon materials as sensing elements due to their unique properties. Graphene is a 2-dimensional material that has a large surface area that can be exposed to...
The application of carbon nanotubes (CNTs) has captivated the curiosity of today's experts due to the escalating potential in the field of electronic detection of biomolecules. Their extreme environmental sensitivity and small size make them ideal...
This thesis reports the reactivity of the trithiolato Ru complex PPN[Ru(DPPBT)3] (DPPBT = 2-diphenylphosphinobenzenethiolate) (1a) with alkenes upon oxidation. Complex 1a in acetonitrile shows two redox events at -345 mV and +455 mV in the square...
The oxidation of metallothiolates is complicated by "non-innocence" or potential
redox activity of sulfur to yield thiyl (RS•) radicals. In some instances, the one-electron
oxidation of metal thiolates yields a product with the unpaired...
This dissertation describes research focused on the synthesis, polymerization and
applications of cationic aminooxy lipids. An efficient and convenient method was
developed to stabilize liposomes using 'click chemistry'. The 'click...
Hematite synthesized by low pressure oxygen plasma has been shown previously to exhibit promising characteristics as a photo-anode for a photoelectrochemical water splitting cell. It is cheap, stable and has a 2.1 eV bandgap and exhibits a...
Periodontitis--Treatment; Peptides--Therapeutic use
Periodontitis and its systemic sequelae remain a major public health problem and
developing a cost-efficient therapy will benefit healthcare worldwide. Adherence of
Porphyromonas gingivalis to Streptococcus gordonii facilitates colonization of the...
For more than a hundred million years, male plethodontid salamanders have
utilized non-volatile, proteinaceous courtship pheromones to regulate female mating
receptivity and promote mating success. These pheromones - which are delivered...
Alcohol; Distillation; Alcoholic beverages; Corn--Utilization; Whiskey industry
In the whisky industry there is a balance between the desire to adhere to the traditional production process and the desire to increase profit margins. One solution that follows both stipulations is to increase the alcohol yield of a given batch of...
Iron oxide, Fe2O3, is a promising material for water splitting reaction using solar
energy due to its stability and optimal bandgap of 2 eV. Even the recent efforts, however,
using Fe2O3 thin film materials reported low efficiencies due to poor...
The role of the active site tyrosine residue in the Co-C5' bond activation in the
context of adenosylcobalamin-dependent mutases has been computationally
investigated. The density functional, complete active space self-consistent field
and quantum...
Acetone--Analysis; Air quality monitoring stations
Zinc oxide (ZnO) based gas sensors with sliver ion exchanged ZSM-5 (Ag+ZSM-5) zeolite overlayer were created and tested for detection of acetone vapor in air. The ZnO and Ag+ZSM-5 films were deposisted on 400µm by 400µm platinum interdigitated...
The vast knowledge of nucleic acids is evolving and it is now known that DNA can adopt highly complex, heterogeneous structures. Among the most intriguing are the G-quadruplex structures, which are thought to play a pivotal role in cancer...
Cancer is the second-most leading cause of death in the United States, with 1.66 million new cases expected to be diagnosed and over 580,000 Americans expected to die of cancer in 2013 alone. (American Cancer Society 2013) Current treatments result...
