1 Solar Fuels: Importance of Material Compatibility in Their Production Irma Rocio Vazquez, Sakineh Chabi Mechanical Engineering Department University of New Mexico AbstractResearch and implementation of clean energy alternatives are paramount, not only for the earth butto more efficiently harness energy from renewable alternatives, such as the sun, which provides10,000 times the daily global energy demand. Artificial photosynthesis, or so-called solar fueltechnology, presents an alluring prospect in harnessing solar energy and offers a

Annual Conference 2intended to allow the drone to quickly intake and expel water samples. Upon testing, the 3D printedmechanism began to deform, restricting the device from being able to pull the syringe in order toobtain the water sample. This malfunction of the 3D printed device was counteracted with theremoval of excess material on the mechanism with acetone [2]. For the Titan drone, this devicewould have to be significantly scaled up so that the syringe would contain enough methane for thejet propulsion of the UAV. The 3D printed design is merely a proof of concept, but also changingthe material of the syringe and the gear step could improve the functionality of the mechanism

This fact has presented a challenge to ensure that all students areappropriately engaged in the material. More recently, some research has focused on using cohortedstrategies to be able to tailor activities to groups of students [12-16]. In Fall 2019, an effort wasmade to enhance student success in this class, not only for concurrently enrolled Pre-Calculusstudents, but for all students. Two sections of the class were created to particularly focus on Pre-Calculus students and their unique struggles with the class, while all others were designed to betaken by

Civil and mechanical engineering also shared the fluidmechanics course.

The frame material was simulated as Alloy Steel, used a Linear ElasticIsotropic model, and the failure criterion was Max Von Mises Stress. The volumetric properties ofthe body are a mass of 405 pounds and a volume of 1455 inches. This equates roughly to a densityof 0.278 pounds per volumetric inch. From these simulations, we determined the table frame willwithstand the expected amount of torque that would occur during operationElectrical

described by Gee 25. Content analysis is a method to systematically compresslarge quantities of material, such as a series of text-based assignments for ease of analysis 24. Usingcontent analysis, researchers look for key words or phrases within a piece of text and attempt tomake various assertions based on the kinds of words (content) that they find. While content analysisinvolves identifying recurring words within texts, Stemler suggests using what he terms “frequencycounts” of concepts that appear across texts rather than word counts: the difference, he states, is thatfrequency counts allow for the examination of the contexts within which those concepts areexpressed. Contet analysis was useful in helping us determine what areas of the
