Graphene Oxide-Based Hole Transport Layers for Organic Solar Cells

By: Yash Sahoo My project involved working with organic solar cells (use organometals instead of purified silicon; function similarly) to reduce the cost of manufacturing cells while keeping similar energy efficiency. Specifically, my project involved working with special thermoelectric polymers which were used as semiconductors with the addition of graphene-based dopants to improve specifically a single layer (hole transport layer). …

Which Factors Increase the Risk of Contracting the Common Cold?

By: Elizabeth Lesher This project was an epidemiological study that seeks to identify both risk and protective factors for the common cold (i.e., characteristics that make a person more or less susceptible to contracting the common cold). To carry out this project, I collected demographic, lifestyle, and genetic information from over 200 participants and used a range of statistical tools …

Biofilm Structure and Formation in Haemophilus ducreyi

By: Delaney Lacey Biofilms are of particular interest to the scientific and clinical community due to the variety of biotic and abiotic surfaces they can colonize. Teeth, surgical instruments, and organs (such as the lungs of cystic fibrosis patients) can all be colonized by a bacterial biofilm. Biofilm formation is characterized by the following steps: signaling by an environmental cue, …
