Foliar Photodegradation In Pesticide Environmental Modeling, Sean M. Lyons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The work described here was conducted to better understand how pesticides will behave following their application to crops or soil. This understanding will allow for better use of pesticides which will protect the environment and non-target organisms while remaining effective against pests. The Pesticide Dissipation form Agricultural Land (PeDAL) model was developed to simulate pesticide behavior following application and laboratory experiments focused on the photodegradation of select pesticides on alfalfa leaves were conducted to support this model.

Renewable Energy Conversion: Organic Redox Flow Batteries And Electrocatalytic Carbon Dioxide Reduction, Camden R. Debruler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Steadily increasing global energy demands have pushed the industry to investigate renewable energy sources like solar and wind to help alleviate the strain on fossil fuel based non-renewable energy sources while also reducing carbon emissions. However, the energy producing power of these renewable technologies is limited by factors such as weather and the day-night cycle. Additional energy storage technologies are needed which are capable of storing excess energy during periods of high productivity, and delivering it when production rates fluctuate.

Batteries represent one possible energy storage device to meet this need. Specifically, redox flow batteries (RFBs) offer advantages in terms …

Developing Advanced Electrodes And Electrolytes For Energy Storage Beyond Li Ion Batteries, Kevin V. Nielson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Electric vehicles, smart phones, and portable computers are all powered by lithium-ion batteries. This is because Li-ion batteries can store more energy in less space than other battery technologies. Also, they are rechargeable and last for a long time. The most recent 2019 Nobel prize in chemistry was awarded to John Goodenough, M. Stanley Whittingham and Akira Yoshino “for the development of lithium-ion batteries”. Through their work, they have made possible cars that do not burn fossil fuels and phones that are wireless and portable. Not only can Li-ion power your phone, it is an incredibly efficient way to store …
