Wearable devices offer promising avenues for health monitoring by potentially integrating heart rate patterns for diagnostic purposes. Watch-like devices are poised to achieve this by monitoring the pulse of the radial artery. Traditionally, this site has been assessed in Oriental medicine, where different pulse fluctuations signify various health conditions. The properties of the skin play […]
C17: Separating Methane and Carbon Dioxide from Biogas using PDMS Membranes
Biogas is a gaseous mixture consisting primarily of methane and carbon dioxide. It is produced from the breakdown of organic waste by microorganisms. Due to the presence of methane, biogas has the potential to be converted into a value-added product. There are currently several methods of separating methane from the other components of a given […]
A57: Building a Compact, Portable IR Viewer for Less Than $250 Using a Raspberry Pi Single-Board Computer
Using readily-available, inexpensive hobbyist components, we have built a handheld portable infrared viewer costing 10X less than its commercial counterpart. A Raspberry Pi single-board computer is used along with touchscreen and camera components. Our product offers larger display size than the commercial unit, a rugged structure, and easier DIY repair.

A74: UV-LED Photocatalytic Device for Fuel Vapor Emission Control
A large percentage of the population in developed countries use automobiles. This directly contributes to the emission of volatile organic vapors into the atmosphere, which in turn affects both humans and the environment. With the creation of a system that is able to reduce fuel vapor emissions, a cleaner and safer environment is generated. Therefore, […]
B70: Investigation of Pyrolyzed Polydimethylsiloxane as an Adsorbent for Pb in Water
Porous materials and mediums such as activated carbon and membranes have been playing a vital role in catalyzing chemical reactions and removing notoriously harmful environmental contaminants. Given the growing population and the rising initiatives to significantly reduce pollution by 2050, the global scientific community continues to remain interested in coming up with low-cost, innovative yet […]
C47-P: Production and Purification of Savinase Protease from B. subtilis
Protease enzymes are widely utilizing in industry in laundry detergents to break down proteinaceous stains as well in pharmaceutical and food industries. A particular serine protease called Savinase shows promise for usage in high pH detergent solutions due to its broad substrate specificity. In this study we aim to produce and characterize recombinant Savinase made […]
