Instrument Building For Detection Of Triplet Signal From Quinolinone Molecules, Brooke Weitzel Jun 2023

Instrument Building For Detection Of Triplet Signal From Quinolinone Molecules, Brooke Weitzel

DePaul Discoveries

Conjugated organic molecules such as the 2-quinolinone family can be used as energy-donor molecules in photocatalysis because of their light absorbing and energy transmitting qualities. Good donor molecules have triplet excited states that are useful for photocatalysis due to their long lifetimes. The goal of this research was to build a near-infrared emission spectroscopy instrument to observe a triplet signal in a set of five previously synthesized 2-quinolinone molecules. A near-infrared absorbance instrument was built successfully with accurate measurements; however, there was no detection of the desired triplet emission signal.

The Influence Of Vehicular Traffic And Land Use Typology On The Spatial Patterns And Concentrations Of Soil Lead (Pb) In The Uptown Community Area Of Chicago, Andreas 'Dre' Harris Jun 2023

The Influence Of Vehicular Traffic And Land Use Typology On The Spatial Patterns And Concentrations Of Soil Lead (Pb) In The Uptown Community Area Of Chicago, Andreas 'Dre' Harris

DePaul Discoveries

Lead (Pb) is a harmful element whose presence threatens the well-being of living organisms and their environments. There are higher concentrations and an increased risk of Pb exposure in areas that provide fewer natural pathways for Pb to accumulate into. In urban areas, the soil is one of the most common and available environmental sinks for Pb accumulation. This study examines the total soil Pb concentrations in relation to land-use types and average daily traffic volumes (cars/day) in each census tract in the Uptown Community Area of Chicago. This study provides insight into how land use and traffic volume may …

Particulate Matter Emissions From Prescribed Burns In The Chicagoland Area, Katherine Petralia Jun 2023

Particulate Matter Emissions From Prescribed Burns In The Chicagoland Area, Katherine Petralia

DePaul Discoveries

Prescribed burns are a land management tool currently used to aid in fire mitigation and promotion of plant growth of desired species and reduction of undesired species, which are often invasive species. Currently there is public stigma surrounding prescribed burns which limits their use in certain parts of the US. There are also particular challenges of conducting prescribed burns in urban and suburban areas. A better understanding of prescribed burns and their impact on atmospheric chemistry and air quality can allow for better communication with the public about their positive impacts and also acknowledge and quantify any potential drawbacks. This …

Modeling Exciton Migration In Two-Dimensional Space, Christian D. Etnyre Jun 2023

Modeling Exciton Migration In Two-Dimensional Space, Christian D. Etnyre

DePaul Discoveries

Computational analysis through density matrix quantum mechanics was performed to model exciton migration in two-dimensional space for a zinc-substituted tetraazaphthalocyanine. The model produced resembles a two-dimensional sheet of molecules. Energy transport mechanisms, controlled by point dipole couplings, were evaluated while altering the size of the crystal lattice. It was determined that energy transport was much more significant with a decreasing size of the crystal lattice. Likewise, the result of increasing the size of the crystal lattice had the effect of dampening the rate of energy transport. It was of interest to determine, with varying crystal lattice dimensions, the time that …

Calculating And Comparing Bioaccessible Lead Concentrations In Soils From The Garfield Ridge, West Elsdon, And Lakeview Community Areas Using A Pbet And A Mehlich-3 Digestion Method, Emma Sznewajs Jun 2023

Calculating And Comparing Bioaccessible Lead Concentrations In Soils From The Garfield Ridge, West Elsdon, And Lakeview Community Areas Using A Pbet And A Mehlich-3 Digestion Method, Emma Sznewajs

DePaul Discoveries

Lead exposure through soil poses potential health risks to those in areas with higher soil-Pb levels, specifically urban areas. The soil-lead concentrations recommended by the EPA are based on measurement of total lead concentration, yet only a percentage of the total lead can actually be absorbed into the body. The percentage of lead in soil that can be absorbed into the blood through ingestion is reffered to as bioaccessible lead and can be a more accurate way of measuring potential dangers of lead in soils. This study measured the amount of bioaccessible lead in the community areas of West Elsdon, …

Understanding The Effect Of Ranching On Quercus Brandegeei Recruitment In The Sierra La Laguna Biosphere Reserve, Xavier O. Espinoza Jun 2023

Understanding The Effect Of Ranching On Quercus Brandegeei Recruitment In The Sierra La Laguna Biosphere Reserve, Xavier O. Espinoza

DePaul Discoveries

In this study, we attempt to deepen our understanding of the mechanisms responsible for Quercus brandegeei’s observed lack of regeneration by identifying which animal species (wild and domesticated) most frequently were observed eating, passing by, or searching for seeds and seedlings. We established 10 paired plots (10 enclosed and 10 immediately outside enclosures) and positioned one motion-activated camera in each plot to observe animal visitations to Quercus brandegeei individuals over the course of several months (October 2019 – March 2020). No seeds and seedlings survived outside of enclosed areas at the end of the study based on their absence. Very …

An Analysis Of Lichen Presence On Quercus And Non-Quercus In Chicagoland Area, Shelby Johnson Jun 2023

An Analysis Of Lichen Presence On Quercus And Non-Quercus In Chicagoland Area, Shelby Johnson

DePaul Discoveries

Both anthropogenic change and the spread of invasive species have led to changes in urban and forest tree diversity. Oak rust, acute oak decline, and emerald ash borer have all had a detrimental effect on tree species in the Chicagoland area. Quercus species are well known habitats for lichen species including Physcia millegrana, Physcia stellaris, Punctelia rudecta, Flavoparmelia caperata, Xanthomendosa, and Candeleria concolor. Due to the decrease in the traditional Quercus habitats for lichen and the increase in nonnative and nontraditional tree species being introduced, particularly in cities, this study aimed to compare the number and diversity of …

Monitoring Personal Exposure To Air Quality Gradients While Biking On An Elevated Urban Trail, Gavin D. Salas Jun 2023

Monitoring Personal Exposure To Air Quality Gradients While Biking On An Elevated Urban Trail, Gavin D. Salas

DePaul Discoveries

Air pollution is a major global health concern, specifically as it relates to the human exposome. The EPA criteria pollutants, including particulate matter (PM), carbon monoxide (CO), carbon dioxide (CO2), and NOx can have severe impacts on respiratory and cardiovascular health, particularly in populations with chronic illnesses such as asthma, those facing economic hardships and individuals who frequently spend time outdoors, such as bicyclists and runners. To understand the impact of air pollution on human health, it is essential to assess personal exposure. This study aimed to investigate personal exposure to air pollution levels while biking along …
