Creating a Less Addictive Opioid using Computational Chemistry

May 11, 2020 by Grand Challenges Initiative | Student presentations

To this day, there is no opioid that binds selectively in peripheral tissue. The binding of opioids in central and peripheral tissues is what results in long term addiction. Opioids, such as morphine, bind at physiological and injured pH. Decreasing the pKa of the morphine molecule leads to selective binding in injured tissues only. The

Assessing Sexual Health Awareness Among Chapman Students

May 11, 2020 by Grand Challenges Initiative | Student presentations

Undergraduates on college campuses often experience new or increasing sexual experiences which can increase the spread of sexually transmitted diseases (STDs). Students experiencing sexual health problems are often faced with multiple concerns regarding obtaining knowledge regarding STDs as well as treatment options. This project aims to easily connect Chapman University students to information concerning sexual

What's Better, Fresh Air or Keck's Air? Comparing Indoor and Outdoor Air Quality

May 11, 2020 by Grand Challenges Initiative | Student presentations

Our team’s grand challenge is investigating and comparing indoor and outdoor air quality in reference to particulate matter. Since PM particles are microscopic, they can be easily inhaled and can cause severe respiratory problems and heart malfunctions that can lead to death. Consequently, we decided to collect and analyze the air quality present and surrounding

Recycling Plastic Waste with a 3D Printer Filament Extruder

May 11, 2020 by Grand Challenges Initiative | Student presentations

In 2017, 348 million metric tons, which is equivalent to the weight of 1,051 Empire State Buildings, of plastic were produced worldwide (PlasticsEurope). The most broad solution to the plastic problem is recycling. In our project, we try to attempt a more profitable and effective solution to help reuse the plastics from the ocean. 3D

Parallax - A Virtual Reality Tool for Teaching Astronomy Concepts

May 11, 2020 by Grand Challenges Initiative | Student presentations

Parallax seeks to be a learning experience that combines traditional teaching methods with virtual reality supplements to enhance student understanding of traditionally taught astronomy concepts. Lecture order and content is based upon the California Department of Education’s standards for 8th graders’ knowledge of astronomy. Lectures are followed by virtual reality sessions which aim to grant

Martian Alfalfa Experiment

May 11, 2020 by Grand Challenges Initiative | Student presentations

We have conducted an experiment that directly compares the growth of alfalfa plants in Terran soil, No Nutrient sand, and Martian soil, both with and without the presence of inoculant. These six soil types were given a few weeks to grow and then were harvested to be analyzed. An R program was written to analyze

Detecting Microplastics in the Environment with Fluorescence Spectroscopy

May 9, 2020 by Grand Challenges Initiative | Student presentations

Our grand challenge is to solve the problem of microplastic pollution in the ocean. We sought to find an efficient method to identify microplastics in natural seawater samples as current sampling methods are costly and time-consuming. Fluorescence spectroscopy was explored and showed promising results as a quick way to differentiate between and identify specific plastic
