Phytochemical characterization of Fagonia indica and its effects on MCF-7 breast cancer cell line

Creator:: Kumbi, Yadano
Abstract:: Phytochemicals from the genus, Fagonia, have been attracting increasing attention due to their potential beneficial effects on human health, particularly, anti-cancer properties. Certain Fagonia species contain various types of phytochemicals such as saponins, alkaloids, cardiac glycosides, flavonoids, terpenoids, and tannins. In this study, we investigated the phytochemical composition of a...

Implementation of a comparative method for measuring photoluminescence quantum yield of novel compounds in solution

Creator:: Brandner, Bret
Abstract:: Quantum yield is an important, characteristic quantity to be measured for fluorescent compounds. Here, a comparative method between fluorescent compounds in solution is applied to measure unknown quantum yields. An absorption spectrometer was used to measure the absorbances of two different fluorescent quantum yield standards. The integrated fluorescence intensities were...

Enzyme-Mediated Conversion of Glucolimnanthin to Bioherbicidal Breakdown Products

Creator:: Bratton, Daniel
Abstract:: The oilseed crop Limnanthes alba (white meadowfoam) is grown in Oregon. Methods were developed for the production of a liquid-based bioherbicide from meadowfoam seed meal (MSM). It was determined that glucosinolate-containing extracts of MSM can be combined with active-enzyme-containing liquid extracts of meadowfoam seed to form a fermented product rich...

Characterization of super-low frequency electromagnetic fields produced by an undersea transmission cable in a homogeneous fluid

Creator:: Pommerenck, Jordan
Abstract:: Offshore renewable energy, an untapped energy resource in the United States, has the potential to stimulate job creation and diversify the world’s energy portfolio. Transmission cables are used to transfer electrical power to the mainland. These cables carry a harmonic time-dependent current. This current in turn generates both an electric...

The Impact of Crystal Morphology on the Opto-Electronic Properties of Amorphous and Organic Crystalline Materials

Creator:: Brandt, Gregory Mirek
Abstract:: Organic aggregates and transparent amorphous metals are transforming opto-electronic devices such as highly efficiency solar cells and flexible displays. We present a fundamental optical study of how local morphology critically impacts the device performance of both stacked, conjugated organics and In-Ga-Zn-O (IGZO) transparent metallic materials. Derivatives of anthradithiophene (ADT): ADTTES-F,...

Toxicity and Mutagenicity of Polycyclic Aromatic Hydrocarbons in Contaminated Soils using Mammalian In Vitro Assay

Creator:: Luker, George W.
Abstract:: There exists a growing need to establish a better in vitro model for evaluating PAH toxicity and carcinogenicity and to improve assessments of risk to human health, especially to the complex mixtures that exist in the environment. Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants due to the incomplete combustion...

Multi-Grand, Multi-Canonical, Flat Histogram, Monte Carlo Simulations for the Square Well Fluid

Creator:: Trotter, Cade W.
Abstract:: Currently multi-canonical, and grand canonical Monte Carlo simulations exist, but do not always give all of the necessary information of the system. When using a 1-D (only changing in one variable) broad histogram Monte Carlo method a user would need to run a range of simulations in order to get...

Electrical Transport Measurements Show Intrinsic Doping and Hysteresis in Graphene p-n Junction Devices

Creator:: Plunkett, Garrett R.
Abstract:: Understanding the electrical transport properties of graphene provides a basis for determining its future as a potential semiconducting device that can be used for the next generation of transistors and photodetectors. Graphene p-n junctions can also function as field effect transistors, and thus are a logical starting point for I-V...

Solution method and error evolution of student responses to chain rule problems within a thermodynamics course

Creator:: Founds, Ian, W and Founds, Ian W.
Abstract:: Chain rules are critical to the process of solving many thermodynamics-related partial derivatives. This study evaluates the solution method and error evolution of students’ responses to a pair of chain rule problems in an upper-level undergraduate thermodynamics course. Students’ responses were categorized by solution method. Students’ solution methods included implicit...
