Geology and its tangential studies, collectively known and referred to in this thesis as geosciences, have been paramount to the transformation and advancement of society, fundamentally changing the way we view, interact and live with the surrounding natural and built environment. It is important to recognize the value and importance of this interdisciplinary scientific field while reconciling its ties to imperial and colonizing extractive systems which have led to harmful and invasive endeavors. This intersection among geosciences, (environmental) justice studies, and decolonization is intended to promote inclusive pedagogical models through just and equitable methodologies and frameworks as to prevent further injustices and promote recognition and healing of old wounds. By utilizing decolonial frameworks and highlighting the voices of peoples from colonized and exploited landscapes, this annotated syllabus tackles the issues previously described while proposing solutions involving place-based education and the recentering of land within geoscience pedagogical models.

Traditional educational infrastructures and their corresponding architectures have degenerated to work in opposition to today's scholastic objectives. In consideration of the necessity of formal education and academic success in modern society, a re-imagination of the ideal educational model and its architectural equivalent is long overdue. Fortunately, the constituents of a successful instructional method exist just outside our windows. This thesis, completed in conjunction with the ADE422 architectural studio, seeks to identify the qualities of a new educational paradigm and its architectural manifestation through an exploration of nature and biophilic design. Architectural Studio IV was challenged to develop a new academic model and corresponding architectural integration for the Herberger Young Scholars Academy, an educational institution for exceptionally gifted junior high and high school students, located on the West Campus of Arizona State University. A commencing investigation of pre-established educational methods and practices evaluated compulsory academic values, concepts, theories, and principles. External examination of scientific studies and literature regarding the functions of nature within a scholastic setting assisted in the process of developing a novel educational paradigm. A study of game play and its relation to the learning process also proved integral to the development of a new archetype. A hypothesis was developed, asserting that a nature-centric educational model was ideal. Architectural case studies were assessed to determine applicable qualities for a new nature-architecture integration. An architectural manifestation was tested within the program of the Herberger Young Scholars Academy and through the ideal functions of nature within an academic context.

This honors thesis is focused on two separate catalysis projects conducted under the mentorship of Dr. Javier Pérez-Ramírez at ETH Zürich. The first project explored ethylene oxychlorination over supported europium oxychloride catalysts. The second project investigated alkyne semihydrogenation over nickel phosphide catalysts. This work is the subject of a publication of which I am a co-author, as cited below.

Project 1 Abstract: Ethylene Oxychlorination
The current two-step process for the industrial process of vinyl chloride production involves CuCl2 catalyzed ethylene oxychlorination to ethylene dichloride followed by thermal cracking of the latter to vinyl chloride. To date, no industrial application of a one-step process is available. To close this gap, this work evaluates a wide range of self-prepared supported CeO2 and EuOCl catalysts for one-step production of vinyl chloride from ethylene in a fixed-bed reactor at 623 773 K and 1 bar using feed ratios of C2H4:HCl:O2:Ar:He = 3:3 6:1.5 6:3:82 89.5. Among all studied systems, CeO2/ZrO2 and CeO2/Zeolite MS show the highest activity but suffer from severe combustion of ethylene, forming COx, while 20 wt.% EuOCl/γ-Al2O3 leads to the best vinyl chloride selectivity of 87% at 15.6% C2H4 conversion with complete suppression of CO2 formation and only 4% selectivity to CO conversion for over 100 h on stream. Characterization by XRD and EDX mapping reveals that much of the Eu is present in non-active phases such as Al2Eu or EuAl4, indicating that alternative synthesis methods could be employed to better utilize the metal. A linear relationship between conversion and metal loading is found for this catalyst, indicating that always part of the used Eu is available as EuOCl, while the rest forms inactive europium aluminate species. Zeolite-supported EuOCl slightly outperforms EuOCl/γ Al2O3 in terms of total yield, but is prone to significant coking and is unstable. Even though a lot of Eu seems locked in inactive species on EuOCl/γ Al2O3, these results indicate possible savings of nearly 16,000 USD per kg of catalyst compared to a bulk EuOCl catalyst. These very promising findings constitute a crucial step for process intensification of polyvinyl chloride production and exploring the potential of supported EuOCl catalysts in industrially-relevant reactions.

Project 2 Abstract: Alkyne Semihydrogenation
Despite strongly suffering from poor noble metal utilization and a highly toxic selectivity modifier (Pb), the archetypal catalyst applied for the three-phase alkyne semihydrogenation, the Pb-doped Pd/CaCO3 (Lindlar catalyst), is still being utilized at industrial level. Inspired by the very recent strategies involving the modification of Pd with p-block elements (i.e., S), this work extrapolates the concept by preparing crystalline metal phosphides with controlled stoichiometry. To develop an affordable and environmentally-friendly alternative to traditional hydrogenation catalysts, nickel, a metal belonging to the same group as Pd and capable of splitting molecular hydrogen has been selected. Herein, a simple two-step synthesis procedure involving nontoxic precursors was used to synthesize bulk nickel phosphides with different stoichiometries (Ni2P, Ni5P4, and Ni12P5) by controlling the P:Ni ratios. To uncover structural and surface features, this catalyst family is characterized with an array of methods including X-ray diffraction (XRD), 31P magic-angle nuclear magnetic resonance (MAS-NMR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). Bulk-sensitive techniques prove the successful preparation of pure phases while XPS analysis unravels the facile passivation occurring at the NixPy surface that persists even after reductive treatment. To assess the characteristic surface fingerprints of these materials, Ar sputtering was carried out at different penetration depths, reveling the presence of Ni+ and P-species. Continuous-flow three-phase hydrogenations of short-chain acetylenic compounds display that the oxidized layer covering the surface is reduced under reaction conditions, as evidenced by the induction period before reaching the steady state performance. To assess the impact of the phosphidation treatment on catalytic performance, the catalysts were benchmarked against a commercial Ni/SiO2-Al2O3 sample. While Ni/SiO2-Al2O3 presents very low selectivity to the alkene (the selectivity is about 10% at full conversion) attributed to the well-known tendency of naked nickel nanoparticles to form hydrides, the performance of nickel phosphides is highly selective and independent of P:Ni ratio. In line with previous findings on PdxS, kinetic tests indicate the occurrence of a dual-site mechanism where the alkyne and hydrogen do not compete for the same site.

With the overall health of the environment rapidly declining \u2014 mostly due to human behaviors, solving the problem of nature deficit disorder and getting more children interested and aware of nature could be paramount to improving the environmental health of our planet. In this study, the relationship between children's learning and emotion is explored. Pre- and post-tests were given to children attending a week-long summer freshwater ecology camp; their knowledge of and emotional connection to different ecological concepts were measured. Two separate ecosystems were tested \u2014 a freshwater ecosystem that was taught over the course of the week, and a marine ecosystem for comparison. Increases in knowledge and emotion were seen in every freshwater ecosystem concept. Additionally, the knowledge and emotion scores were correlated, suggesting a positive relationship between them. The marine ecosystem did not show improvements in concrete knowledge, but showed increases in abstract learning, indicating that the abstract concepts learned about the freshwater ecosystem were able to transfer to the marine. Overall results show the ability of a hands-on learning experience to foster an emotional connection between a child and the subject matter. However, long-term studies are needed to track the relationship between children and their knowledge of and emotional connection to the subject matter.

Current literature on sustainability education and its core competencies (systems thinking, normative, interpersonal, strategic, and future thinking) has yet to acknowledge the K-12 level, concentrating instead on higher-level institutions. To initiate study at the critical K-12 level, a curriculum module composed of four lessons to address the wicked sustainability problem of drought in the Sonoran Desert was developed, piloted, and evaluated. The framework of each lesson combined the core competencies and the 5Es pedagogy (engage, explore, explain, elaborate, and evaluate). Two lessons were successfully piloted in two seventh grade middle-school science classes in Phoenix, Arizona. Topics addressed were the water cycle, types of drought, water systems, and mitigation methods. Evaluation determined a high level of student engagement. Post-pilot teacher questionnaires revealed a high degree of support for inclusion of sustainability education and core competencies addressing drought in future opportunities. It is concluded that lessons in the future can adopt the core competences of sustainability with the support of educators in Arizona.

This 15-week long course is designed to introduce students, specifically in Arizona, to basic sustainability and conservation principles in the context of local reptile wildlife. Throughout the course, the students work on identifying the problem, creating visions for the desired future, and finally developing a strategy to help with reptile species survival in the valley. Research shows that animals in the classroom have led to improved academic success for students. Thus, through creating this course I was able to combine conservation and sustainability curriculum with real-life animals whose survival is directly being affected in the valley. My hope is that this course will help students identify a newfound passion and call to action to protect native wildlife. The more awareness and actionable knowledge which can be brought to students in Arizona about challenges to species survival the more likely we are to see a change in the future and a stronger sense of urgency for protecting wildlife. In order to accomplish these goals, the curriculum was developed to begin with basic concepts of species needs such as food and shelter and basic principles of sustainability. As the course progresses the students analyze current challenges reptile wildlife faces, like urban sprawl, and explore options to address these challenges. The course concludes with a pilot pitch where students present their solution projects to the school.

An exploration of how architecture can react to American hyper-consumption of clothing products. With the goal to raise public awareness and create systemic, sustainable change in the fashion industry, this project synthesizes each part of manufacturing, including production, consumption, and post consumption, into one local campus. By bringing manufacturing back into the daily rhythms of an urban context and combining a prototypical mix of fashion related programs, ethically minded consumers are formed.

Literature on the topics of education and religion suggests that there is a relationship between the two, one which could be assessed as positive or negative depending on the religion. One religion whose impact on people’s educational experience has recently become of interest is the Jehovah’s Witness religion. By analyzing the narratives of people who once practiced as Jehovah’s Witnesses, this paper sought to investigate how religion can impact people’s educational experience, and whether there is a positive or negative relationship. I utilized questions from the Life Story Interview with a framework of analysis that corresponds to common themes in narrative research. My data results consist of narratives from three different participants, which I analyzed according to different narrative themes. The analysis of my data indicated that active members of the Jehovah’s Witness community admitted to feeling less confident in pursuing education. This finding indicated that Jehovah’s Witnesses as students have unmet needs during their years of primary education, such as social support from peers and family members and an understanding of how educational opportunities would benefit them. Findings of the study also indicate that high school teachers might be well-positioned to provide social support and educational information for students in religions like the Jehovah’s Witness religion. Future research could focus on investigating the best practices for teachers to utilize when meeting the needs of students who belong not just to the Jehovah’s Witness religion but to religious minority groups overall.

As the canonical literature, student competencies and outcomes, and foundational courses of sustainability education are contested and reaffirmed, grounding this academic discipline in an experiential understanding of place is not often asserted as a core aspect of sustainability curriculum. Place can act both as a context and conduit for sustainability education, inspiring student investment in local communities and stewardship of the landscape. Through narrative descriptions of interviews held with professors, program coordinators, and deans from nine sustainability undergraduate programs across the United States, I explore in this thesis how different educators and institutions adopt place-based pedagogy within sustainability curriculum and institutional practice. In observation of these interviews, I name three factors of difference – physical and social setting, academic ethos, and institution size – as axes around which place is incorporated in sustainability instruction and within the college as a whole. Finally, I give general recommendations for incorporating place in sustainability instruction as well as certain creative and place-oriented assignment structures discussed in the interviews.
