Variability In The Fabrication Process Of Bivo4 Photoanodes, Lauren M. Phillips
Senior Honors Projects, 2010-2019
Hydrogen gas produced from the photoelectrochemical (PEC) decomposition of water, using sunlight as an energy source, is a promising approach for sustainable fuel production. This decomposition of water is also called artificial photosynthesis. A device that accomplished this process is sometimes call an artificial leaf, which mimics nature inasmuch as it stores solar energy as a chemical fuel (e.g., hydrogen) by splitting water, in this way imitating natural photosynthesis. In 2009, Dr. Keith Holland and Dr. David Lawrence of James Madison University (JMU) initiated a research program to investigate materials for the photoelectrochemical decomposition of water into hydrogen and oxygen, …

The weathering and erosion of weak rocks along roadways can cause dangerous and potentially fatal rockfalls. Various slope stabilization methods exist, but each presents a set of challenges and trade-offs. The focus of the project is to understand the feasibility of utilizing of a polymerbased slope stabilization technique. Rock samples were collected along US Route 33 in Virginia and West Virginia, and preliminary tests were conducted to evaluate the absorption of water (% mass) and durability. The study evaluates three polymer options in regard to the following criteria: adhesion to rock, layer thickness, semi-permeability, insolubility, and non-toxicity. The polymer selection …
