Rechargeable Al-Co2 Battery Using A Homogeneous Catalyst, Christopher Fetrow

Shared Knowledge Conference

Metal-CO2 batteries have emerged as a promising strategy to improve energy storage technology while capturing/concentrating carbon dioxide. The Al-CO2 battery has been previously as a primary battery to have an excellent discharge capacity when a small amount of oxygen is introduced. Herein we demonstrate an Al-CO2 battery that uses a homogeneous iodine-based redox mediator to enable the reversible discharge and charge of the battery with an ultra-low overpotential of 0.05V. By replacing oxygen gas with aluminum iodide in the electrolyte of the previously primary-only configuration, the battery maintains a high discharge capacity and can be recharged for 12 cycles at …

Reimagining Ceremonial And Domestic Living Within The Navajo Hogan, Courteney Begay

Shared Knowledge Conference

Throughout the history of colonization and "Native American" (Indigenous) tribes within the U.S have endured the deconstruction of culture, tradition, language, and sacred structures. All of which are part of sharing cultural identity to future generations and the continuance of self-identity for tribes throughout the U.S. This leads to my research question "How can the Navajo Hogan be structurally modified for contemporary living while upholding cultural values, traditions and history it represents?" Starting with one tribe as a beginning of future design knowledge for others. The Navajo Hogan is a sacred dwelling embedded with many stories, cultural teachings, and traditional …

Distribution Of Irrigation Water Creates Barriers To More Efficient Water Use On Middle Rio Grande Farms, Eleanor Hasenbeck

Shared Knowledge Conference

New Mexico's water supply is decreasing under climate change, driven by a decrease in snowpack and resulting runoff and an increase in evaporation under warmer temperatures. Current models predict that in the next 50 years, less water will be available for all water users in the state, which will require community leaders to make difficult decisions to manage a finite water supply. About 80% of New Mexico's total water use is currently used in agriculture, making up the largest water use by sector in the state. For this reason, agriculture is often looked to as an area of opportunity to …

An Examination Of Ingan Micro-Led Carrier Dynamics Through Small Signal Rf Analysis, Elizabeth Dejong

Shared Knowledge Conference

Light-emitting diodes (LEDs) are by far the most efficient and customizable light source commercially available. While large-area LEDs already have a wide range of uses and represent a massive decrease in energy costs and consumption compared to conventional light sources, applications such as directional lighting, digital displays, and visible light communication would benefit from a reduction in LED source size. Smaller light sources can achieve higher precision directionality, higher display resolution, and faster modulation. Micro-LEDs, usually defined as having a diameter of 50 μm or less, therefore have the potential to further reduce energy consumption and increase functionality. However, micro-LEDs …

Investigating Poly (1,2-Butylene Fumarate) Biopolymer For Applications In Bone Tissue Engineering, Jasmine Jackson

Shared Knowledge Conference

INTRODUCTION: Synthetic biopolymers allow for the creation of bone scaffolds which degrade and may be designed to encourage regeneration of new bone tissue. A common biopolymer for bone tissue engineering poly (propylene-fumarate)(PPF) has been found to have mechanical properties similar to that of native bone; however, former research has suggested its slow degradation rate can pose issues in bone tissue regeneration applications. This research introduces poly (1,2-butylene fumarate)(1,2-PBF) as a potential material for 3D bioprinting of bone tissue scaffolds. METHODS: 1,2-PBF synthesis is done via a polycondensation reaction of fumaryl chloride and 1,2-butanediol using a nitrogen sparging method in which …

Ethics Of International Surrogacy, Himanshi Arora

Shared Knowledge Conference

In this poster I intend to explore the ethics of international surrogacy in India. In a developing nation like India, there are different perspectives on surrogacy along with its advantages and drawbacks. Some see it as a win-win situation, by helping women from an impoverished background to earn money for their families and at the same time helping foreign parents get a child to love and care for. On the other hand, some see it as exploitation and abuse, taking advantage of poor women for the benefit of parents from wealthier nations. From 2005-2015, surrogacy clinics were a booming industry …

Fabricating Silicon Nitride Microrings For Optical Frequency Comb Generation, Gabriel Colacion

Shared Knowledge Conference

Since their invention over two decades ago, optical frequency combs have enabled dramatic advances in the way we measure light and time. The utility of these devices follows from their characteristic output of broadband optical frequencies along with their well-timed pulsed output. Optical frequency combs are now used in a multitude of applications including microwave and optical frequency generation, synchronization between state-of-the-art atom-based clocks, as well as atomic and molecular spectroscopy. However, the complexity and scale of optical frequency combs generally limits them to specialized optics laboratories. In response, there has been a significant effort to leverage advances in nano- …

Bye Bye Brasil And A Febre: Race, Change, And National Belonging In Brazil, Laura Cruz

Shared Knowledge Conference

National identity is a concept that permeates every aspect in the formation of a nation. In Brazil, national identity is formed by a varied social landscape of races, ethnicities, and origins. However, in a context of increasing modernization, how do communities that have been forcibly introduced or excluded in the nation view their own national identities? Bye Bye Brasil (1980) and A febre (2019) are two important Brazilian films in which Afro-Brazilian and Native Brazilian characters, respectively, confront the spaces reserved for their communities in their national lived realities. In this project, I examine how Bye Bye Brasil and A …

The Deconstruction Of Heteronormativity And The Presentation Of Eco-Anxiety In Dystopian Novels Written By Women, Lea Briere

Shared Knowledge Conference

Through an analysis of two modern dystopian novels written by Michelle Tea and Wendy Delorme, I will explore how ecological catastrophes and societal changes are the triggers for the deconstruction of heteronormativity. Following traditions of dystopian narratives, those novels delve into notions of reproduction, nature as an escape, patriarchal expectations, anxiety, and feeling of belonging. Themes such as queer identities, queer relationships, subjectivity, and identity, but also eco-anxiety and solastalgia are also challenged in these texts. My first interest is in the environment and the feeling of belonging of a community and an individual in their habitat. Solastalgia is a …

Aging And Learning: Community Engagement And Self-Efficacy In L2 Teaching To Elderly Students, Leticia Rinaldi

Shared Knowledge Conference

The elderly population (60 years or older) has been increasing in numbers during the past decades around the world and is expected to reach the number of two billion by 2050 (Scult, Haime, et al 2015; Santos, 2019). In Brazil, the aging population numbers are rising more rapidly compared to the global tendency (Alves, 2020). However, the misconception that elderly people are uncapable or incompetent is still part of the imaginary constructed around the elderly population (Minichiello & Coulson, 2005). These perceptions shape the access of older population to resources that are accessible to younger sections of society, causing elderly …

Polyphonic Spectatorship, Creative Cartography, & Post-Cinematic Refractions In The Age Of Neo-Liberal Travel, Niko Doezema

Shared Knowledge Conference

Today, the most visible and popular form of travel "literature" is the "travel-vlog", an amorphous category which can pertain to any first-person, audio-visual exploration of place. YouTube is awash in travelers from every conceivable place documenting their adventures in every conceivable destination, and their content is disseminated instantaneously and simultaneously through the ever present yet intangible and amorphous conduit of the internet. My thesis consists of a three-fold investigation into the nature of this genre, the first two branches of which are genealogical and diagnostic, the third of which is speculative and potentially transformative. Having established a historical and technological …

Student Water Scholars And Broader Impact Outreach: Motivations And Hinderances To Participation, Sydney Donohue

Shared Knowledge Conference

Universities serve as a hub for the advancement of water science and engineering knowledge and innovations. However, much of that expertise does not reach communities that could benefit from such knowledge. Many universities and research centers attempt to address this by organizing broader impact outreach events. Anecdotally, we have seen that of a pool of approximately 100 water-focused students, only the same small subset participates in every event while over 70% of those invited never volunteer to participate. Therefore, there is a need to assess students' motivations and hindrances for volunteering. This study aims to survey undergraduate and graduate student …

Shared Knowledge Conference

This (ongoing) study examines the role of family members in cancer clinical trial decision-making among minority groups. It explores the patterns of family communication and involvement and out they both influence decision-making to (not)participate in CCT. Three four themes emerged from analyzing in-depth interviews of 23 family members: 1. Narrative construction of care; 2. Constrained treatment options and timeliness; 3. Significance of community outreaches; 4. Collective emotions. The study found diverse communication strategies that are deemed essential for cancer clinical trial recruiters to have for successful recruitment.

The Interplay Between Acute Stress And Antimicrobial Peptide Modulation In The Fish Skin, Yago Santos

Shared Knowledge Conference

The fish skin is a crucial first line of defense against different external threats. Among these dangers, several sources of stress, such as overcrowding and transportation, are often associated to intensive aquaculture. Thus, fish requires efficient mechanisms to sense and respond to those danger signals. In fish, the skin produces a large amount of mucus, that covers and protects the whole body. Within the mucus layer, several molecules can directly interact and kill pathogens, one of them are beta-defensins. Beta-defensins are antimicrobial peptides present in almost all animals, including fish. As in humans, beta-defensins are highly expressed in the fish …

Molten Salt Pump Bearing Design And Test, Yuqi Liu

Shared Knowledge Conference

Fluoride Salt Cooled High-Temperature Reactors (FHRs) use particle fuel, graphite moderator, and molten fluoride salt coolant for power generation and process heat applications. The main loop of the FHR is a closed loop, operating at slightly above atmospheric pressure, with fluoride salt temperatures exceeding 600 °C. Reliable high-temperature molten salt pumps are critical to the successful deployment of FHRs. To stabilize the rotating shaft and reduce the associated coefficient of friction, molten salt pumps require well-designed bearings. Therefore, it is necessary to study the detailed hydrodynamic performance of bearings under high-temperature molten salt conditions. In the current study, a computational …

Continuing New Mexican Agricultural Customs: A Proposal To Combat The Drought Of Accessibility In The Middle Rio Grande Region, Corina Gomez

Inequity By Inequity: Community Driven Investigation Of Wheelchair User Discomfort By Infrastructure Failures, Steven Mccullough, Jessica Eisma, June Young Park, Mikila Salazar, Sarah F. Rose

Association of Computing Machinery Open Access Agreement Publications-Archive

Wheelchair users face a variety of disability-related inequities in the built environment. The primary challenge is that current legislation for relieving disability inequities focuses on design guidelines and less so in monitoring their discomfort. While there is literature about monitoring wheelchair users, there is little available data regarding wheelchair user discomfort across the built environment. Therefore, we create a transformative approach to measure a wheelchair user’s personal comfort (WheelCom) using open-source solutions, allowing more citizens to engage in the inequity challenge. To demonstrate, we lectured our approach to local high school students to develop WheelCom. Subsequently, actual wheelchair users measured …

Browse all Datasets

Black raspberries (BRB) are rich in anthocyanins with purported anti-inflammatory properties. However, it is not known whether dietary supplementation would ameliorate Western-diet enhanced gut inflammation and colon tumorigenesis. We employed a mouse model of colitis-associated colorectal cancer (CAC) to determine the effects of dietary supplementation with 5 to 10% (w/w) whole, freeze-dried BRB in male C57BL/6J mice fed either a standard healthy diet (AIN93G) or the total Western diet (TWD). In a pilot study, BRB suppressed colitis and colon tumorigenesis while also shifting the composition of the fecal microbiome in favor of taxa with purported health benefits, including Bifidobacteria pseudolongum. …

Teacher Stress And Work-Family Conflict: Examining A Moderation Model Of Psychological Capital, Mustafa Toprak, Rasim Tösten, Zakir Elçiçek

Faculty Journal Articles

Schools are becoming more stressful work environments, and teachers are becoming more vulnerable to job-related stress because of innovation overload, high job demands, and work-family conflict (WFC). Enhancing teachers’ psychological capacities may prove helpful in managing stress under such work conditions. While past research has focused on the relationship between WFC and stress, there is limited empirical evidence in the education context on the effect of psychological capital (PsyCap) on changing the magnitude of (moderating) the interplays between WFC and stress. Therefore, this study investigates the moderation effect of teachers’ positive PsyCap on the relationship between teachers’ WFC and job …

Low-Cost Sustainable Engineered Geopolymer Composites (Egcs) For Repair And New Construction Of Transportation Infrastructure, Hassan Noorvand, Marwa Hassan, Miladin Radovic, Svetlana Sukhishvili, Gabriel Arce, Ruwa Abufarsakh, Adriana A. Alvarado, Oscar Huang, Sang Zhen

Data

This study evaluated the use of cost-effective alternative materials in the formulation of novel low-cost Engineered Geopolymer Composite (EGC) materials for repair and new construction of transportation infrastructure in Region 6. Previous studies and reports have shown that EGCs have excellent mechanical properties, which makes them an eco-friendly and more sustainable alternative to Engineered Cementitious Composites (ECCs). However, the mass adoption of these emerging composites is expected to be hindered by their cost, which is mainly driven by the use of PVA reinforcing fibers, silica fume (SF), and manufactured microsilica sand (MS). To address this key shortcoming, novel low-cost EGC …
