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).

The depiction of mental illness, schizophrenia in particular, within film is a unique phenomenon that film directors have decided to undertake more so in the last 20 years than ever before in cinematic history (Wedding & Niemic, 2014; Robinson, 2004; Gabbard & Gabbard, 1999; Wahl, 1997). Countless filmmakers have taken on the challenge of depicting this complex, yet degenerative condition that entails auditory and visual hallucinations, disorganized thought and speech, and delusions. Its portrayals are usually exaggerated and romanticized, and convey a sense of separate "Otherness" with those who have a mental disorder. And while filmmakers try to encapsulate the schizophrenic experience, it is not without psychiatric error and regarding the person who has schizophrenia as a spectacle. This unfair and ostracizing view of people who have schizophrenia is fueled by films like A Beautiful Mind and The Shining where the film either creates impossibly high standards for schizophrenics to perform at, or the film paints the character as a violent savage. In either case, the end result is the marking and, usually, denouncement of the schizophrenic for their illness. What filmmakers tend to overlook is how much the public learns from the cinematic portrayals of these disorders, and that their films are contributing to an overarching issue of public presumptions of actual schizophrenia and how it is perceived. While the Hollywood approach offers a depiction that is usually more tangible and enjoyable for masses of audiences, spectators should recognize that these are artistic interpretations that take liberties in their depictions of schizophrenia. Viewing these films with an objective mindset to better understand the inner workings of schizophrenia is absolutely crucial in arriving anything close to the truth behind this mental illness that has been demonized long enough.

Description
This thesis outlines the process of creating the concept work behind a television series called Liminality, written by my thesis partner, Elizabeth Hansen. Liminality aims to be an animated series about West Elliot Snow as he navigates his life as a spiritual medium and how this talent impacts his daily life. It is a coming of age story centered around West and his recently departed father, Lukas Snow, whose spirit is still tethered to the land of the living. Together, the two must learn how to control their powers while helping other spirits who have unfinished business on the earthly plane. It explores themes of sexuality and gender identity as well as non-nuclear family structures as a means of giving voice to those who have felt a lack of representation in mainstream media. In this paper, I explore the depth of the creative process from conceptualization to realization of character designs, scripting for the series, 3D modeling of characters and sets, and finally, the storyboarding of the pilot episode. I start by asserting why a series like Liminality would positively influence the already burgeoning creative landscape of television. Liminality's relevance in today's television market is explained through examples of series that aim to broaden the amount of representation given to underrepresented peoples and identities in mainstream media. From there, I outline which series influenced the process of writing Liminality and why. After that, I delve into the specifics of how Elizabeth and I designed the characters and what decisions went into the final product.

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.

This work examines three common practices—yellowface in Cloud Atlas (2012), whitewashing in Star Trek Into Darkness (2013), and absence in Firefly (2002)—employed in popular science fiction that represent Asianness and disregard the Asian body. Though the creators purport to have progressive ideals at the center of their production choices, their works call on Techno-Orientalist and Orientalist tropes and divorce them from the Asian body, implicitly continuing the Orientalist argument of Western supremacy even in representing Asianness.
