Description
Abstract "Empty Horizons": A Creative Writing Piece Max Harmon "Empty Horizons" is a creative writing piece composed of two different short stories sharing a common narrator. The first story "Can you dig it?" details a trip the narrator takes to South Dakota to go hunting shortly before starting college. On the trip the narrator contemplates certain aspects of his life and the events of the story serve as a vehicle to explore the narrator's mindset as an eighteen year old about to start a new phase in his life. The second story "Toads, Sharks and Beautiful Encounters with Uncertainty" takes place during the summer before the narrator begins his last semester in college as he attends the funeral of his recently deceased grandmother in Hawaii. During the trip to Hawaii, the narrator meets a girl his age and they are able to bond with each other over feelings of loss and uncertainty. In this story the narrator explores his feelings about life with college graduation on the horizon and comes to terms with some of the anxieties that have been plaguing him since the start of college. By detailing these two distinct and important time periods in the narrator's life the reader is able to gain a sense of understanding in regards to the narrator's own process of beginning life as an adult.

Description
Due to the environmental problems caused by global warming, it has become necessary to reduce greenhouse gas emissions across the planet. Biofuels, such as ethanol, have proven to release cleaner emissions when combusted. However, large scale production of these alcohols is uneconomical and inefficient due to limitations in standard separation processes, the most common being distillation. Pervaporation is a novel separation technique that utilizes a specialized membrane to separate multicomponent solutions. In this research project, pervaporation utilizing ZIF-71/PDMS mixed matrix membranes are investigated to see their ability to recover ethanol from an ethanol/aqueous separation. Membranes with varying nanoparticle concentrations were created and their performances were analyzed. While the final results indicate that no correlation exists between nanoparticle weight percentage and selectivity, this technology is still a promising avenue for biofuel production. Future work will be conducted to improve this existing process and enhance membrane selectivity.

Description
The goal of this research project is to create a mixed matrix membrane that can withstand very acidic environments but still be used to purify water. The ultimate goal of this membrane is to be used to purify urine both here on Earth and in space. The membrane would be able to withstand these harsh conditions due the incorporation of a resilient impermeable polymer layer that will be cast above the lower hydrophilic layer. Nanoparticles called zeolites will act as a water selective pathway through this impermeable layer and allow water to flow through the membrane. This membrane will be made using a variety of methods and polymers to determine both the cheapest and most effective way of creating this chemical resistant membrane. If this research is successful, many more water sources can be tapped since the membranes will be able to withstand hard conditions. This document is primarily focused on our progress on the development of a highly permeable polymer-zeolite film that makes up the bottom layer of the membrane. Multiple types of casting methods were investigated and it was determined that spin coating at 4000 rpm was the most effective. Based on a literature review, we selected silicalite-1 zeolites as the water-selective nanoparticle component dispersed in a casting solution of polyacrylonitrile in N-methylpyrrolidinone to comprise this hydrophilic layer. We varied the casting conditions of several simple solution-casting methods to produce thin films on the porous substrate with optimal film properties for our membrane design. We then cast this solution on other types of support materials that are more flexible and inexpensive to determine which combination resulted in the thinnest and most permeable film.

Description
The scarcity of fresh water worldwide has necessitated improved technology for desalinating sea water. Reverse osmosis membranes are currently limited by their inclination for fouling, in which a layer forms on the surface of the membrane and impedes water flux. This yields shortened membrane lifespan and increased energy costs. Current technology uses interfacially polymerized polyamide thin film composite membranes, which form nodules, leaves, and other structures that lead to rough film surfaces and may contribute to fouling propensity. In this study, polyamide latex was designed in order to cast a smoother membrane with comparable performance. Polyamide latex particles were formed using a modified procedure based on Lind et. al [10] and characterized for sphericity using scanning electromagnetic microscopy (SEM).

Description
Based on paradigms in feminist theory and criticism, I conduct an analysis of two iconic works of twentieth century American feminist literature. Examining Herland (1915) by Charlotte Perkins Gilman and Rubyfruit Jungle (1973) by Rita Mae Brown, I assess their place within the canon of feminist literature--a canon traditionally thought of as Western. I cyclically explore how this canon parallels movements and institutions in actual feminism, and where the pitfalls in both can be traced. Due to the large span of time betwixt the two novels, I engage the historical progression American women experienced in the twentieth century and pair it with the progress feminist literature was likewise experiencing. Exploring the consequences of depicting women as people rather than male counterparts or others, I analyze the roles of the male gaze, male-less spaces, utopias, construction of female identity, motherhood, and how these culminate in feminine and sexual liberation. Utilizing philosophy from Christine de Pizan’s The Book of the City of Ladies and Simone de Beauvoir’s The Second Sex, I trace the origins of the male gaze and male-less spaces in literature and film and how women are essentially othered. I further employ the criticism of Adrienne Rich’s essay “Compulsory Heterosexuality and Lesbian Existence” to explore the roles of motherhood and heterosexual norms specifically. My findings deride the authors for their inability to construct legitimately liberated female protagonists. However, I simultaneously offer deference to the authors for engaging the tools and concepts they had available to them at the time in the interest of crafting powerful feminist narratives. I center on the claim that male-less spaces are difficult to fully as well accurately portray in literature, but the authors attempt to do so to move towards a liberation of women and should be lauded for the contributions they made.

Description
Paraprosdokian is a collection of stories about all different types of lives in Phoenix, AZ. There are several stories that work together, involving lonely teenagers at punk house shows, while the rest standalone: the eclectic interactions of a waiter at a 24-hour diner, a blind fair ride operator with a propensity for accidental murder, a hapless son of a clumsy dental assistant, a literary scholar stuck in an addiction to both Kafka and pornography, a kid who learns that writing is not a formula, and a high school death that nobody cares about. Some pieces unfold parts of 21st century culture that have been knotted in ambivalence, like how men raised on pornography reconcile with intimacy, while others are as simple as trying to encapsulate the experience of growing up in what is often perceived as an artless suburbia. The project aims at mixing prose with photography to create, as Ben Lerner describes it, “a constellation of language and image”—a complete artistic product. Using the work of a local Arizona photographer, the collection complicates a reader’s elementary notion of a “picture book” by forcing the reader to view photographs beyond exposition or symbolism. The title of the collection comes from a term used in comedic rhetoric that refers to a figure of speech in which the latter part of a statement or phrase reorients one’s understanding of the whole. Under this definition, the collection seeks to amend its author and reader’s orientation to Phoenix in a quest for empathy, giving pathetic characters a chance to speak without ever sacrificing a touch of humorous joy.

Description
The recovery of biofuels permits renewable alternatives to present day fossil fuels that cause devastating effects on the planet. Pervaporation is a separation process that shows promise for the separation of ethanol from biologically fermentation broths. The performance of thin film composite membranes of polydimethylsiloxane (PDMS) and zeolite imidazolate frameworks (ZIF-71) dip coated onto a porous substrate are analyzed. Pervaporation performance factors of flux, separation factor and selectivity are measured for varying ZIF-71 loadings of pure PDMS, 5 wt%, 12.5 wt% and 25 wt% at 60 oC with a 2 wt% ethanol/water feed. The increase in ZIF-71 loadings increased the performance of PDMS to produce higher flux, higher separation factor and high selectivity than pure polymeric films.

Description
In this research, construction of a model membrane system using Polyvinylidene Chloride-Co Acrylonitrile and Linde Type A zeolites is described. The systems aims to separate out flow through zeolite pores and flow through interfaces between zeolites and polymers through the use of pore filled and pore open zeolites. Permeation tests and salt rejection tests were performed, and the data analyzed to yield approximation of separated flow through zeolites and interfaces. This work concludes the more work is required to bring the model system into a functioning state. New polymer selections and new techniques to produce the membrane system are described for future work.

Description
This thesis aims to evaluate how in classroom demonstrations compare to regular education techniques, and how student learning styles affect interest in science and engineering as future fields of study. Science education varies between classrooms, but usually is geared towards lecture and preparation for standardized exams without concern for student interest or enjoyment.5 To discover the effectiveness of demonstrations in these concerns, an in classroom demonstration with a water filtration experiment was accompanied by several modules and followed by a short survey. Hypotheses tested included that students would enjoy the demonstration more than a typical class session, and that of these students, those with more visual or tactile learning styles would identify with science or engineering as a possible major in college. The survey results affirmed the first hypothesis, but disproved the second hypothesis; thus illustrating that demonstrations are enjoyable, and beneficial for sparking or maintaining student interest in science across all types of students.

Acute Kidney Injury (AKI) may be detected through biomarkers in urine. This research is being done to develop a membrane for use in separating urine biomarkers to monitor their level. A hydrophobic membrane was treated to improve separation of the desired biomarker for colorimetric sensing. This method was tested with model solutions containing the biomarker. Future work will extend to testing with real urine.
