Life Cycle Assessment And Comparison Of Magnesium Oxide Nanoparticles Prepared By Aqueous And Microwave Synthesis Methods, Jesse Cartland
Materials Engineering
Abstract: Magnesium oxide nanoparticles are being used increasingly as catalysts for organic synthesis, fuel oil additives, and CO2 adsorbents. There are many ways to produce magnesium oxide nanoparticles, but there is little information available regarding the environmental costs of production. As demand for environmentally friendly materials increases, it is important to understand environmental impact differences between various production methods. This study will compare the differences in embodied energy and global warming potential (GWP) between two synthesis methods: microwave combustion synthesis (microwave synthesis) and oxidation of magnesium hydroxide (aqueous synthesis). The resulting nanoparticles were characterized using scanning electron microscopy (SEM), …

Life Cycle Assessment Of Paper Versus Electronic Assignment Submission In Cal Poly's Materials Engineering, Patrick Mcdonnal
Materials Engineering
Both hard and soft copy submission of assignments make an impact on the environment to produce the final product in terms of energy consumption and carbon emissions; an investigation was conducted as to which method is less environmentally impactful. Student disposition towards each assignment submission method was also investigated because it is associated with learning efficacy. A survey was conducted in Cal Poly’s Materials Engineering Department to determine the contributing components to the environmental impact of paper and electronic assignments, as well as the students’ disposition towards each of them. Contributing components are man-made products used by a student to …
