Inspired by this palate of lively, idiosyncratic street designs—created out of necessity by people making-do—this project seeks to bring identity, value, and vitality to this challenging human environment.
This project uses concepts and processes of disturbance ecology and ecological succession, specifically the role played by pioneer species and biological legacies in the immediate aftermath of the eruption of Mount St. Helens, to develop an urban revitalization plan for Buckeye Road.
The product developed is called Neomod, a modular shoe system. People buy shoes both for fashion and function, with the average American owning nineteen pairs. However, countless numbers of partially worn shoes end up in landfills because the materials they are made of are difficult to separate and replace. This is why we designed Neomod; a modular shoe made with interchangeable parts. It makes recycling shoes simpler, but at the same time, provides users with a variety of styles to mix and match to fit their lifestyle. Neomod’s goal is to minimize the amount of waste created and allows all parts of the shoe to be used until its end of life. As consumers buy, recycle, and reuse Neomod shoes, they will help the world work towards a more circular economy.
The author concentrates on examining Islamic traditional architecture where the past architects incorporated certain aspects of nature in their construction and through using local resources, built buildings that mitigated heat and provided protection from cold. As a result of completing this research, it was found that there are common characteristics between the traditional Islamic architecture elements and system solutions found in some natural organisms. Characteristics included, for example, evaporative cooling, stuck effect, and avoiding heat gain. However, in the natural world, there is always opportunities to further explore more about the impacts of biomimicry and natural strategies applicable to enhance interior environments of buildings.
The first part of this dissertation describes the preparation of three different types of proton reduction catalysts. First, four bioinspired diiron complexes of the form (μ-SRS)Fe(CO)3[Fe(CO)(N-N)] for SRS = 1,2-benzenedithiolate (bdt) and 1,3-propanedithiolate (pdt) and N-N = 2,2’-bipyridine (bpy) and 2,2’-bypyrimidine (bpym), are described. Electrocatatlytic experiments show that although the byprimidinal complexes are not catalysts, the bipyridyl complexes produce hydrogen from acetic acid under reducing conditions. Second, three new mononuclear FeII carbonyl complexes of the form [Fe(CO)(bdt)(PPh2)2] in which P2 = bis-phosphine: 4,5-Bis(diphenylphosphino)- 9,9-dimethylxanthene (Xantphos), 1,2-Bis(diphenylphosphino)benzene (dppb), or cis- 1,2-Bis(diphenylphosphino)ethylene (dppv) are described. All are functional bio-inspired models of the distal Fe site of [FeFe]-hydrogenases. Of these, the Xanthphos complex is the most stable to redox reactions and active as an electrocatalyst. Third, a molybdenum catalyst based on the redox non-innocent PDI ligand framework is also shown to produce hydrogen in the presence of acid.
The second part of this dissertation describes creating functional interfaces between chemical and biological models at electrode surfaces to create electroactive systems. First, covalent tethering of the redox probe ferrocene to thiol-functionalized reduced graphene oxide is demonstrated. I demonstrate that this attachment is via the thiol functional groups. Second, I demonstrate the ability to use electricity in combination with light to drive production of hydrogen by the anaerobic, phototrophic microorganism Heliobacterium modesticaldum.
The Sonoran Desert in the Southwest region of the United States and the Northwest corner of Mexico is defined by low precipitation rates that are episodal, oscillating between years of higher yields than average and then below average levels. Water is essential for life and in the region, the lack of water proves an obstacle for people that must be faced to live and thrive there. Yet, millions of people live in this desert region and more people are moving currently. As current water resources are straining not only under increasing population but also with higher frequency and lengths of droughts in the region, water is becoming an important topic for future plans in the Sonoran Desert. However, a vast array of plants and animals have lived under these conditions by adapting to the low precipitation rates. By looking at the common flora and fauna of the region, humans may learn how to better live in the Sonoran Desert through biomimicry, the imitation of life. The natural design and processes of life in the Sonoran Desert can be studied to find ways to conserve, store and collect water for human consumption ensuring longevity within the region and beyond as water insecurity increases globally.
