Mapping Plastic Pollution In The Amite Watershed, Louisiana, Gourav Divan Jun 2021

Mapping Plastic Pollution In The Amite Watershed, Louisiana, Gourav Divan

LSU Master's Theses

Microplastics have quickly emerged as a concerning pollutant in both freshwater and marine environments. Their recent discovery means that their impacts are still being studied, however, it is important to continuously monitor their concentrations. An important conduit of plastic pollution to marine environments are rivers and streams. Previous models have estimated the transport of plastics from land to sea in many parts of the world. Most of these models, however, have been conducted at coarse spatial resolutions that make it difficult to establish tractable management programs to minimize this impact. Here, a previously existing model was applied to model for …

Engineered Nanostructured Nitrogen-Doped Carbon Network (Ndc) Electrodes With Unprecedented Cycling Stability For Water Capacitive Deionization In Harsh Conditions, Soha Essam Anwar

Theses and Dissertations

Capacitive deionization (CDI) is a feasible low-cost desalination technique for low-to-medium (brackish) salinity water. However, cycling stability and regeneration of the CDI electrodes are the bottlenecks hindering the practical application of the technology on large scale. Oxidation of the electrodes during the sequential adsorption-desorption processes is one of the most challenging problems hindering their long-term cycling performance. Herein, we demonstrated the ability to design and fabricate exceptionally stable CDI electrodes via a one-pot pyrolysis protocol. The optimized pyrolysis of nitrogen-carbon precursors at different temperatures enabled the fabrication of carbon materials with a controlled amount nitrogen dopant (NDCs) with exceptional cycling …

How State Interventions Affect Municipalities Taking The Lead In Sustainability, Jayce L. Farmer, Andres J.Rodriguez Lombeida Jun 2021

How State Interventions Affect Municipalities Taking The Lead In Sustainability, Jayce L. Farmer, Andres J.Rodriguez Lombeida

Public Policy and Leadership Faculty Research

The state and local governments throughout the United States interact within a complex system of multilevel governance to advance sustainability. However, we know little about what this hierarchical system of exchanges means for municipalities as they work to achieve energy efficient government operations. Drawing on a perspective of “contested federalism”, we examine how the transaction costs of state–local government relations affect the efforts of U.S. cities to lead by example and promote sustainability within their internal processes. We apply a Bayesian item response theory approach to assess the effects of state-level fiscal and policy interventions on municipal commitments to energy …
