Novel Approaches to Evaluate the Environmental Impacts of Nanomaterials

Creator:

Wu, Fan

Abstract:

Numerous studies have shown that some nanomaterials are highly toxic to aquatic organisms and can potentially disrupt overall community health; however, current methods to evaluate the nanomaterials environmental impacts rarely consider the environmental realism or provide sufficient detail on the impact at the community level. Here we demonstrate three approaches...

Addressing the Risks of Nanoscale Polymers: Exposure, Behavior, and Toxicity

Creator:

Stine, Jared

Abstract:

Nanoscale polymers (including nanoplastics) are widely present through commerce and make their way into the environment. As the improper disposal of plastic waste leads to continued accumulation and degradation of plastic pollution, the presence of plastic particles less than 1 micron (μm) in size (nanoplastics) will increase. Heightened concern over...

Addressing Persistent Challenges in Nanotoxicology Exposures : Techniques for in situ Characterization

Creator:

Crandon, Lauren E.

Abstract:

Nanoparticles (NPs), defined by their size (1-100 nm), are increasingly incorporated into commercial and industrial products due to their high surface area and unique properties. They can be designed for specific applications by manipulating composition, size, shape, and surface functionalization. As NP production and complexity increases, there is a need...

The Influence of Engineered Surface Coatings on Nanoparticle Aggregation and Corona Formation: Examinations in Simulated and Real Aquatic Media

Creator:

Surette, Mark C.

Abstract:

Engineered nanomaterials (ENMs) are small anthropogenic colloids with at least one length dimension <100 nanometers. Due to the nature of their use, ENMs are being increasingly released to the environment. Yet the environmental risks posed by ENMs are unknown due to a variety challenges, including limitations with detecting and quantifying...

Examining the Environmental Behavior and Treatment Efficacy of Titanium Dioxide Nanomaterials in Complex Systems

Creator:

Deline, Alyssa R.

Abstract:

Metal oxide nanoparticles (MONPs) are manufactured at the greatest rate of any class of nanomaterial due to their wide variety of industrial, commercial, and environmental applications. The sustainable use of MONPs requires a balance of careful consideration of their potential negative environmental impacts with the effective exploitation of their unique...

Aromatic hydrocarbon contaminants : investigations of detection methods, bioremediation strategies, and toxicity impacts

Creator:

Huizenga, Juliana M.

Abstract:

Aromatic hydrocarbons represent a large class of environmental contaminants that have a broad range of structures, physicochemical properties, and toxicities. Arising from the burning of organic matter, particularly fossil fuels, they are both widespread and abundant in all environmental compartments. Both monoaromatic hydrocarbons (BTEX) and polycyclic aromatic hydrocarbons (PAHs) are...

Eco-corona formation and impact on environmentally relevant micro- and nanoplastics

Creator:

McColley, Campbell J.

Abstract:

Microplastics (MPs) are plastic particles less than 5 mm in diameter. These contaminants are increasingly found in the environment due to increased plastic production, use, and improper disposal. Detecting and measuring these contaminants in the environment has proven difficult, requiring the use of fate and transport models to assess MP...

Engineering an Ex-Vivo System to Study Transport Phenomena in the Human Intervertebral Disc

Creator:

Shalash, Ward

Abstract:

Back pain is the leading cause of disability worldwide, entailing a significant socioeconomic impact. A primary source of back pain can be attributed to intervertebral disc (IVD) degeneration allowing nerve ingrowth, facet joint arthritis, disc bulging, and osteophyte formations that press on nearby nerve roots or the spinal cord. While...

Transgender and Gender Nonconforming Undergraduate Engineering Students: Perspectives, Resiliency, and Suggestions for Improving Engineering Education

Creator:

Haverkamp, Andrea E.

Abstract:

Gender has been the subject of study in engineering education and science social research for decades. However, little attention has been given to transgender and gender nonconforming (TGNC) experiences or perspectives. The role of cisgender or gender conforming status has not been investigated nor considered in prevailing frameworks of gender...

Probing Structure, Selectivity, and Orientation of Biomolecules to Cell Membranes by Sum Frequency Generation

Creator:

Golbek, Thaddeus W.

Abstract:

Cell membranes act as barriers against unwanted movement of ions and biomolecules and are complex surfaces littered with protein channels, ion channels, cholesterol, and a myriad of different proteins. While this surface is extremely well studied, there is still much we do not know. The work in this dissertation demonstrates...
