As access to potable water grows scarce, there is an increasing reliance on alternative drinking water sources, namely groundwater (WHO, 2018). Chlorinated solvents, such as 1,1,1-trichloroethane (TCA) and 1,2-cis-Dichloroethene (cisDCE) are some of the most ubiquitous groundwater contaminants spread throughout the US. 1,4-dioxane (1,4D) was used primarily in the late...
The ability of nanoparticles (NPs) to induce oxidative stress on organisms has been linked to NP cytotoxicity and genotoxicity for a variety of organisms. One proposed mechanism of this increased oxidative stress is the ability of NPs to generate reactive oxygen species (ROS). Due to the dynamic nature and small...
Sepsis is a life-threatening blood infection which leads to an uncontrolled systemic inflammatory state. In North America alone, sepsis annually afflicts approximately 750,000 individuals and kills 38-50% of these (more than HIV/AIDS, breast cancer, and colon cancer combined). Current treatment involves administration of IV fluids, antibiotics and hemoperfusion, requiring prolonged...

Currently, wax printing is limited to materials that can be processed by a wax printer. Wax transfer printing is a method that allows previously unusable materials to be patterned with wax via an intermediate template. Millipore cellulose, a material too thick to be processed by a wax printer, was patterned...
Xanthan gum, a naturally produced polysaccharide, is biocompatible, and it is commonly used as a food additive. When combined with trivalent ions, such as chromium (III), a gel can form. Various concentrations of xanthan gum and chromium (III) nitrate were combined to evaluate the sol-gel transition of this system. Samples...
Nitrate (NO₃-) accumulation in water sources is a serious health and environmental concern. Common methods used to reduce NO₃- accumulation have one or more undesirable traits that limit their efficacy in large-scale decontamination. However, treatment of NO₃- electrochemically is a promising area of study because of the absence of toxic...
Technology is constantly co-evolving with science to produce simple and effective tools that address the needs of researchers. Cost and time effective point-of-care devices are valuable for sample collection and analysis, particularly in medicine and environmental health and safety. Digital microfluidic (DMF) technology provides a possible solution. This study explores...
The factors that cause abdominal aortic aneurysm rupture were investigated. Included
in this study were aneurysm volume, thrombus thickness, lumen area, thrombus area,
the average stress acting on the aorta, and the maximum stress on the aorta. The
geometric values were obtained by tracing a series of computerized axial tomography...
The development of simple, rapid, and sensitive methods for thiophenol detection is of great importance in various fields, including environmental monitoring and food quality. Here, we present a novel approach for the colorimetric detection of thiophenols using gold nanoparticles (AuNPs) as the sensing platform. AuNPs aggregate in the presence of...
Presented here is an investigation and comparison of two entrapment methods of algae. Conventional calcium alginate bead entrapment is compared to a recently described modified bead entrapment method, utilizing poly(ethylene glycol) and calcium alginate, which results in void or capillary formation within the beads. It is shown that algal growth...
