Stability And Redispersion Of Platinum Nanoparticle Suspensions For Attachment To Dyes In Low-Cost Solar Cells, Jeffrey Rothstein
Stability And Redispersion Of Platinum Nanoparticle Suspensions For Attachment To Dyes In Low-Cost Solar Cells, Jeffrey Rothstein
Honors Scholar Theses
The project involves optimizing the synthesis, washing, and redispersion of platinum nanoparticles. The nanoparticles are to be attached to dye molecules where they will act as nanocatalysts to reduce energy losses in low-cost dye-sensitized solar cells. The goal is to develop a process based on a pure or mixed solvent that will maintain a stable dispersion of the nanoparticles without interfering with their ability to bond with the dye molecules in the solar cell.

Theses and Dissertations
Other than water, portland cement concrete is the most used commodity. Major parts of civil and transportation infrastructure, including bridges, roadway pavements, dams, and buildings are made of concrete. Because of wide-scale applications of these important structures in different climatic zones and associated exposures, concrete durability is often of major concern. In 2013, the study of American Society of Civil Engineers (ASCE) estimated that one-third of America’s major roads are in poor or mediocre condition [1]. The same article reports that annual investments of $170 billion on roads and $20.5 billion for bridges are needed to substantially improve the condition …
