Biennial Conference: The Social Practice of Human Rights
Human rights, human development, and climate change clearly overlap in many ways. Development, as quantified by the Human Development Index (HDI), for example, has historically been strongly correlated with energy consumption. This fact is recognized in Sustainable Development Goal (SDG) 7, to “ensure access to affordable, reliable, sustainable and modern energy for all.” Currently the world is in the midst of a large wave of human migration, much of it involuntary and due to stymied development opportunities as well as political upheaval. Climate change will become, or already is, an exacerbating factor in migration dynamics.
A pertinent question is how …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Thermal conductivity is an important material property which affects the performance of a wide range of devices from thermoelectrics to nanoelectronics. Information about phonon vibration modes and phonon relaxation time gives significant insight into understanding and engineering material’s thermal conductivity. Although different theoretical models have been developed for studying phonon modes and relaxation time, extensive knowledge of lattice dynamics and molecular dynamics is required to compute phonon modal frequencies and relaxation times. Therefore, a computational tool which can take simple inputs to calculate phonon mode frequencies and relaxation time will be beneficial. Through this research work, such computational tool has …

The Summer Undergraduate Research Fellowship (SURF) Symposium
In modern engineering applications, system overheating is a key issue that needs to be solved with efficient and reliable cooling technologies. Among the possible mechanisms that these are based on, natural convection cooling is one of the most frequently employed, with applications ranging from cooling of computer micro-components to large nuclear reactors. While many studies have been performed on natural convection employing supercritical or subcritical fluids, little attention has been given to fluids in their transcritical regime. The latter has the potential to yield high performances while avoiding detrimental effects of two-phase systems (e.g. cavitation). In the present study, 2D …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Understanding drop breakup will optimize aircraft engine performance, reduce agro-chemical overspray, and improve pharmaceutical tablet efficacy. Large fuel fragments in engines lead to lowered fuel economy and higher pollutant emissions, while small drops yield more agro-spray drift into surrounding residential and environmental zones. Better pharmaceutical tablets will improve drug uptake and patient comfort.
Engineers and scientists are currently unable to predict the number, size, and velocity of fragments formed during important drop breakup processes. Therefore, we are required to measure these quantities. We use digital inline holography (DIH) to record three-dimensional diameter and position data for fragments formed during multi-mode …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Numerous people live or venture into environments, such as the Middle East, where the temperatures can skyrocket as high as 54°C. This leaves many air conditioners unable to operate efficiently. Although much research has been conducted for incorporating vapor injection processes into refrigeration systems, such as ones used in supermarkets, little has been researched regarding the application in extreme heat environments. While most basic air conditioning units do not require the addition of a vapor injection process along with an economizer, this project requires the air conditioning (AC) unit to operate under extreme high temperature conditions. The project investigates the …

ENERGY Research and Lesson Plans
Students will participate in a Solar Panel Cricket lab to determine which environmental condition would allow for the solar panel to produce the most power. The three conditions are inside, inside with a flashlight, or outside in the sun. The students will complete a correlating lab worksheet. Students will also ask questions and hold discussions with the guest speaker. Students will actively participate while the guest speaker is presenting.

ENERGY Research and Lesson Plans
Background- Photovoltaic (PV) cells produce the largest amount of electricity when they are directly facing the sun. Solar panels that use tracking systems to position the panel to constantly face the sun have the greatest efficiency. But, these systems are expensive.
Aim- Design a dual axis tracking solar panel with microcontroller and sensors (light, humidity, temperature, and compass) that are both cost effective and efficient. Sensors will be used to determine performance depending on environmental factors.
Ethics Statement: Researchers will keep honest, clear, and accurate records when collecting all data in lab and communication of information learned.
