The cosmetic industry utilizes plastic for most of its packaging, as it is a cheap option that produces packaging that is highly durable and resistant to many chemicals. Polyethylene terephthalate (PET) is the most commonly used plastic in cosmetic packaging, and is an ideal candidate for recycling due to their short lifespan and low diffusion coefficient. However, cosmetic packaging is often not recycled properly due to its small size, contributing to the growing global plastic waste problem. If a sustainable closed-loop system was created where cosmetic packaging was created using purely recycled PET, then the amount of plastic produced could be reduced. By examining the mechanical properties of recycled composite PET from the cosmetic industry, conclusions can be drawn about its applicability in cosmetic packaging. The water absorption, UV-visible absorbance, and tensile strength was tested for recycled composite PET to predict how the material would perform if it was used in cosmetic packaging. It was found that the recycled composite PET did not perform as well as virgin PET in terms of water absorption and tensile strength, but performed similarly in reference to UV-visible absorbance. More research needs to be done to further characterize the mechanical properties of recycled composite PET before it can be used in cosmetic packaging, but this study analyzes three of the most prominent aspects found in cosmetic packaging.

This thesis project is part of the W.P. Carey Founders Lab, a collaborative entrepreneurship track that gives students the opportunity to create a start-up business based on a list of given problems or technologies. The technology selected utilized a piece of NASA technology (U.S. patent application 20200193857) that combines mixed, virtual, and augmented reality (MR, VR, and AR) with biofeedback metrics to help athletes get in the zone. The goal is to use the technology during practice so athletes can be better prepared to combat performance anxiety during high-pressure situations. The NASA patent states that if the user’s brain activity, sweat, or heartbeat indicate that they are stressed while completing the activity, the device will make it more difficult for the athlete to complete their task. ITZ’s device increases the difficulty of hitting a target with a ball by obscuring the vision with augmented reality graphics. The visual obstacles will subside if the user’s brain activity metrics indicate that they have become more calm or focused. Due to circumstances outside of the team's control, a prototype was unable to be obtained, and the idea was based on the patent and supporting documentation provided after a meeting with NASA.

The cosmetic industry has a significant lack of data on sustainability practices. The global market for cosmetics is expected to grow from $288 billion in 2021 to $415 billion in 2028 as more people populate the globe (Cosmetics Market Size, Share, & COVID-19 Impact Analysis, 2022). This research paper analyzes sustainability within the cosmetic industry. Specifically, comparing the practices between The Body Shop and Bath & Body Works. To test the hypothesis that The Body Shop is more sustainable than Bath & Body Works, a case study analysis was conducted to measure the companies’ performance in the environmental, economic, and social sectors. Comparable metrics were selected, and a pairwise comparison was completed to weigh the different metrics. To analyze the results, the Analytic Hierarchy Process (AHP) was used to ensure consistency in metric weights, and a Mann-Whitney U test was used to analyze the sector's final weights. The results verified the hypothesis that The Body Shop was more sustainable than Bath & Body Works. In all, the results support the idea that the cosmetic industry needs stronger regulations and oversight of cosmetic companies’ sustainability impact. One of the most prevalent limitations of this study is the lack of transparency and information from cosmetic companies. Moving forward, it is recommended to use data from multiple years with key performance indicators (KPIs) to assess sustainability performance more accurately.

Climate change is one of the most pressing issues of the generation. Both faith organizations and scientific research are striving to solve problems related to climate change. Both show significant motivations to act on the effects that global warming is predicted to have. Combining the motivations and finding common ground could be the key to changing the fundamental issues that lead to climate change and both sides need each other to carry out the goal of preventing climate change. Some potential outcomes of cooperation are explored and the impact that these measures could have are described. These effects will be synthesized from previous research on the subjects, compiling qualitative data on the motivations and effects of both religion and science on climate change.

Cyanidioschyzon merolae, a unicellular extremophilic red algae, is found in hot, acidic groundwater with high concentrations of heavy metals. The association makes it an ideal species to investigate mechanisms of heavy metal tolerance, which may lead to its use in phyco- remediation wherein photosynthetic algae use biological processes to bind and remove toxic substances. Two strains of C. merolae, MS1 and 10D, are genetically very similar, despite the latter lacking a cell wall. To investigate heavy metal toxicity and the role of the cell wall, the two strains of C. merolae were exposed to various concentrations of cadmium and cultures were evaluated spectrophotometrically to assess the impact on growth over a 7-day period. The IC50 values of MS1 and 10D were estimated to be 15 and 0.5 ppm CdCl2 respectively, indicating that the cell wall provides protection under the presence of heavy metals. Cadmium uptake was also measured using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) to investigate metal ion exclusion and acidocalcisome-Cd2+ chelation as potential tolerance mechanisms. ICP-OES data indicated that 10D inoculum pretreated with phosphate depletion and re-supplementation, to induce Cd chelation in acidocalcisomes, then cultured in MA2 had the highest biomass Cd content of all strains and treatments (0.321 ppm; 31.55%). The cell wall clearly promotes survival and resistance to higher concentrations of environmental heavy metals, however, neither MS1 nor 10D seemed to be strains primed for phyco-remediation of heavy metal contamination through cellular uptake and sequestration.

The COVID-19 pandemic caused uncertainty and changing public health recommendations across the world as our understanding of the SARS-CoV-2 virus changed. Following a preliminary assessment by the World Health Organization, non-steroidal anti-inflammatory drugs were said to worsen symptoms and should be avoided before the recommendation was subsequently revoked. There also was pain associated with infection, leading to the hypothesis that use of over-the-counter pain medication increases may correlate with increases of SARS-CoV-2 infections. Wastewater samples were collected from two communities in Tempe, AZ from December 2019 to July 2020 (n = 35) and were analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS) to identify levels of acetaminophen, ibuprofen and their metabolites, acetaminophen sulfate and carboxy-ibuprofen. Results showed 100% detection frequency of all analytes in all samples across the duration of the study. Mass loadings of acetaminophen (918.4 g day-1 +/- 354.8 g day-1) were higher than ibuprofen (182.9 g day-1 +/- 49.8 g day-1), potentially driven by flushing behaviors rather than consumption activities. However, ibuprofen was more heavily consumed than acetaminophen across all days of the study period. Comparisons to COVID-19 clinical cases data showed increased use in ibuprofen with increases in clinical cases loads, while acetaminophen showed no change, suggesting ibuprofen was the over the counter (OTC) medication of choice during the first wave of the pandemic.
