Plastic pollution is an ever-increasing environmental threat. As large-scale plastics break down to form nanoscale plastics, it is essential to investigate their effects on freshwater ecosystems. With many plastic nanoparticle (NP) studies favoring the effects of common polystyrene (PS) plastics, a gap is formed for other common plastic types like...
Social vulnerability is often thought of as a culmination of social factors influencing the susceptibility of various groups to harm and govern their ability to respond. In an effort to identify communities that may be susceptible to social impacts from changes to fishery policies or fishing conditions, NOAA Fisheries is...
Quantitative assessments of many West coast rockfish stocks of both major and
minor importance to commercial fisheries have shown varying declines in abundances. The population sizes of less-abundant, co-occurring unassessed species may also be
declining. However, determining stock status of the many non-targeted, minor species with high levels of certainty...
Hydrophobic titanium dioxide (TiO2) nanoparticles (NPs) are prevalent in industry and manufacturing. They are known for their white pigmentation, are found in sunscreens, paints, cosmetics, and are frequently used in wastewater treatment. Understanding the physicochemical properties of TiO2 P-25 NPs, such as hydrophobicity, are essential when determining their fate, transport,...
Plastics have become an essential part of everyone lives, found in almost every product made today. Tires only make up a fraction of these products but as their use increasing so does the microplastics that flake off. Many studies have evaluated the toxic effects of tire particles on aquatic environments...
As nanoparticle (NP) research and development expands, the significance of NP biodistribution effects on toxicity increases. A reliable method for measuring NP biodistribution is critical. Hyperspectral Imaging (HSI) is capable of accurately quantitating NP biodistribution within embryonic zebrafish with incredibly high precision. Before HSI processing, the embryo must be sectioned...
Antimicrobial agents are being increasingly used in consumer soaps and detergents, despite a lack of data demonstrating their efficacy in such products. This study investigated the nature of the interaction between different crystalline structures of titanium dioxide nanoparticles and BTC, and explore which structure, if any, could be best used...
The United States of America is founded upon immigration, and Germans are one of the first European ethnic groups to settle en masse in North America. The common narrative of immigration is that of the “melting pot”; characterized by assimilation of cultures into one ‘super’ culture. German immigration has often...

Nanoparticles (NPs), particles defined by their size in a single dimension (1-100 nm), are being increasingly incorporated into commercial and industrial products due to their high surface area to volume ratio that gives them unique properties, such as optical tunability and higher reactivity than their bulk counterparts. NPs can be...
Dendrimers are well-defined, polymeric nanomaterials currently being investigated for their biomedical applications. Initially, higher generation (size) dendrimers were of interest because of their drug carrying capacity. However, increased generation was associated with increased toxicity. The objective of the present study was to investigate the role of surface charge and generation...
