Description
The goal of this research project is to create a Mathcad template file capable of statistically modelling the effects of mean and standard deviation on a microparticle batch characterized by the log normal distribution model. Such a file can be applied during manufacturing to explore tolerances and increase cost and time effectiveness. Theoretical data for the time to 60% drug release and the slope and intercept of the log-log plot were collected and subjected to statistical analysis in JMP. Since the scope of this project focuses on microparticle surface degradation drug release with no drug diffusion, the characteristic variables relating to the slope (n = diffusional release exponent) and the intercept (k = kinetic constant) do not directly apply to the distribution model within the scope of the research. However, these variables are useful for analysis when the Mathcad template is applied to other types of drug release models.

Description
Cardiac tissue engineering is an emerging field that has the potential to regenerate and repair damaged cardiac tissues after myocardial infarction. Numerous studies have introduced hydrogel-based cardiac tissue constructs featuring suitable microenvironments for cell growth along with precise surface topographies for directed cell organization. Despite significant progress, previously developed cardiac tissue constructs have suffered from electrically insulated matrices and low cell retention. To address these drawbacks, we fabricated micropatterned hybrid hydrogel constructs (uniaxial microgrooves with 50 µm with) using a photocrosslinkable gelatin methacrylate (GelMA) hydrogel incorporated with gold nanorods (GNRs). The electrical impedance results revealed a lower impedance in the GelMA-GNR constructs versus the pure GelMA constructs. Superior electrical conductivity of GelMA-GNR hydrogels (due to incorporation of GNRs) enabled the hybrid tissue constructs to be externally stimulated using a pulse generator. Furthermore, GelMA-GNR tissue hydrogels were tested to investigate the biological characteristics of cultured cardiomyocytes. The F-actin fiber analysis results (area coverage and alignment indices) revealed higher directed (uniaxial) cytoskeleton organization of cardiac cells cultured on the GelMA-GNR hydrogel constructs in comparison to pure GelMA. Considerable increase in the coverage area of cardiac-specific markers (sarcomeric α-actinin and connexin 43) were observed on the GelMA-GNR hybrid constructs compared to pure GelMA hydrogels. Despite substantial dissimilarities in cell organization, both pure GelMA and hybrid GelMA-GNR hydrogel constructs provided a suitable microenvironment for synchronous beating of cardiomyocytes.

Description
There is a wide intersection where animal and human lives interact or mimic each other behaviorally or biologically. A lot of the products that are part of our day-to-day were first validated by animals, and eventually found their way to us. From food to beauty products to scientific developments, animals deal with a lot behind the scenes. Some humans are cognizant of what is happening backstage, while others only see the final presentation. Either way, all of us have our opinions in support or against animal treatment. The project is heavily inspired from my experience in a neurorehabilitation lab, so the foundation is similar to the structure and function of neurons. Through this project, I am focusing on one aspect of this debate, which is animal testing in the scietific setting. The goal of the project is not to force the viewer to choose one side, but to understand the big picture and the reasoning of the opposing side.

Description
The goal of this project was to create a card game that would quickly and easily allow medical professionals to learn important information. This project seeks to advance ways in which medical staff gain information about disease outbreaks through the creation of a card game which teaches players the proper steps and procedure to triage and treat patients who are suspected to have Ebola Hemorrhagic Fever, which was not done properly during the recent outbreak. To create this game, research was conducted on the information given by the Center for Disease Control and Prevention (CDC) on the various steps to triaging those who were suspected of having Ebola. Various prototypes of the game were made and tested to optimize the win-lose ratio while still being an enjoyable game to play. This card game is fast-paced, small, and can be played either individually or with more than one person. It is loosely based off of Solitaire. This game has gone through three prototypes of the cards as well as a few brief testing periods. Through the methods and procedure used in this game's creation, it has been concluded that this method is a great way to easily teach players a proper procedure, and that this method of game can be applied to other disease breakouts and even to other fields where information must be learned quickly. Future steps for this game include improving the graphic art used in the cards, and continuing on to create a smartphone application.

Description
The Honors Creative Project evolved drastically from start to finish, despite its origin remaining the same. My core goal in this project was to connect two seemingly mutually exclusive aspects of my life, engineering and dance. After conducting an IRB study and using data from my own personal experiences, I was able to see how dance had in fact made me a better engineer. There were skills that I gained and learned in dance that were directly applicable to engineering, and I believe will be critical to my success as an engineer. As the focal point of the project angled towards myself, I had to look deeply into who I am and how I reached this point. I conducted self-reflections on various aspects of my current life and also on the struggles and hardships I overcame during my years at ASU. From these reflections, I learned a lot about myself and how my personal identity has evolved. This identity evolution became the backbone behind my thesis defense. I took my research and self-reflections and designed a series of artwork that I personally designed and painted myself. I my engineering side to conduct the research and collect the data, and then used my artistic side to present my findings to the public in a way that attracted and audience and caused others to reflect upon their own identities.

Description
There is an increasing interest in developing thermo-responsive polymers for treating aneurysms. In this thesis project, the potential for poly(NIPAAm-co-JAAm-co-HEMA-Acrylate) (PNJHAc) as a treatment method for brain aneurysms was investigated. Five different batches of polymer were synthesized, purified, lyophilized, and characterized using nuclear magnetic resonance and cloud point techniques over the course of several months. Two were tested in aneurysm models. Of these five batches, there were two that showed promise as liquid embolic agents for endovascular embolization.

Description
The goal of this creative project is to document my grandmother’s traditional Gujarati recipes with the hopes of preserving her life and passion for cooking. This process included library research to investigate the history of Indian and Gujarati cuisine, spending time in the kitchen documenting the recipes in their entirety, practicing them on my own, writing the cookbook and including passages that weave in the history, my grandmother’s stories, and techniques and tools. After completing this process, the significant findings related to my grandmother’s life and her journey from birth to now. Her marriage to my grandfather at a young age, her journey and those who influenced her ability to cook, and her impact on my family were all effects that I had understood and known during my experiences with my grandmother. In this journey, I learned more about her thoughts and experiences that I never knew before. Our relationship has deepened ten-fold and while she may not be with me forever, I now have a tangible part of her that I can keep with me for the rest of my life.

Description
Plastics make up a large proportion of solid waste that ends up in landfills and pollute ecosystems, and do not readily decompose. Composites from fungus mycelium are a recent and promising alternative to replace plastics. Mycelium is the root-like fibers from fungi that grow underground. When fed with woody biomass, the mycelium becomes a dense mass. From there, the mycelium is placed in mold to take its shape and grow. Once the growth process is done, the mycelium is baked to end the growth, thus making a mycelium brick. The woody biomass fed into the mycelium can include materials such as sawdust and pistachio shells, which are all cheap feedstock. In comparison to plastics, mycelium bricks are mostly biodegradable and eco-friendly. Mycelium bricks are resistant to water, fire, and mold and are also lightweight, sustainable, and affordable. Mycelium based materials are a viable option to replace less eco-friendly materials. This project aims to explore growth factors of mycelium and incorporate nanomaterials into mycelium bricks to achieve strong and sustainable materials, specifically for packaging materials. The purpose of integrating nanomaterials into mycelium bricks is to add further functionality such as conductivity, and to enhance properties such as mechanical strength.

Description
Engineering is a heavily male-dominated field and females are significantly less likely to choose an engineering-related major or career path. At the age of six years old, females start believing that their male peers are smarter than them, leading them to pursue less ambitious careers. The children's book Lyla B. An Engineering Legacy was created to encourage more young girls to discover their own potential and pursue engineering as a career. To explore the efficacy of the book on its target consumers, a pilot study was performed with first and second grade children. The participants' engineering knowledge; fixed and failure mindset beliefs; STEM (Science, Technology, Engineering, and Math) interest, competency, and career aspirations; and stereotype beliefs were evaluated before and after being read the book to determine if the story has a positive impact on children. Additionally, the satisfaction of the participants towards both the book and main character were analyzed quantitatively and qualitatively. Overall, the results of the study suggest that the book has a positive impact on the interest and competency of STEM fields and the stereotype beliefs that the children had towards engineers. The study also suggests that the book decreases fixed and failure mindsets and that the participants were satisfied with the overall concept of the book and main character, Lyla.

Description
The novella Flicker by Rachel Ponstein is a climate fiction story. It draws influence from the post-apocalyptic and dystopian genres as well as classic gothic literature. The story utilizes elements of gothic literature including Freud's Uncanny, uneven framing, and bildungsroman. It also utilizes subhuman species to incite conversation about the importance of perspective and the use of an alternative lens on the post-Reckoning world. The disaster story is ambiguous to focus the reader on the importance of the characters and their progress throughout the journey rather than the overall plotline. The analysis below serves as an explanation for the intentional decisions made to fit a sub-genre and engage the reader in an intellectual conversation about the issues broached.
