Title: Energy Management in Microgrids
Abstract: A microgrid, an emerging technology in the electric power systems, has various benefits due to the implementation of distributed energy sources along with the loads. A microgrid utilizing the wind energy, solar energy, combined heat and power, natural gas generator, diesel generator, and battery storage is considered in an islanded mode of operation. The economic dispatch optimization is implemented using a reduced gradient algorithm to optimize the Operation and Maintenance cost in the islanded mode of the microgrid. The cost of each energy source is evaluated for every hour of the day using MATLAB code. Then, the availability of each energy source in the microgrid is evaluated. The results obtained are validated by comparing the Operation and Maintenance cost and the availability of each energy source in the microgrid. The optimal solution is achieved by considering the change in wind forecast and battery energy storage profiles.

Title: Systematically Influencing Function and Optical Properties in Porphyrin Proteins by Fine-Tuning their Active Sites
Abstract: Porphyrin proteins are ubiquitous in nature, as they are present in bacteria, plants, and mammals. The structural nature of the pigments or co-factors in these proteins has evolved to fully optimize the function of the biomolecule. This presentation explores the structure-function relationship in proteins from various organisms studied throughout the speaker’s career, focusing on their optical spectroscopic properties and electronic structures as guiding parameters. In particular, the enzymes that will be discussed are Cyt P450cam, myoglobin, and human serum albumin complexed with heme, and their function in reacting with NOx species (e.g. nitrite reduction) or oxidizing sulfur-containing compounds (e.g. oxidative desulfurization). Key sites in the structure of the protein are systematically fine-tuned, and their spectroscopic and kinetic properties are investigated. Results from this work provide a foundation for designing enhanced catalysts based on the nitrite reductase or desulfurase activities of porphyrin proteins.

Title: The Charge of Command- Leading Engineering, Technical and Tactical Nuclear Powered Submarine Teams in Arduous Environments
Abstract: The safe and effective operation of US Nuclear Powered Submarines is one of the most demanding missions in the US Department of Defense. Submarine crews are high performance teams that must operate in unusually arduous conditions, in port and at sea, to ensure the safe operation of a nuclear propulsion plant and extended months-long operations when deployed. These teams must often make split-second decisions that impact the lives of the crew, the safety of the submarine, and the outcome of national security missions. This discussion will provide my perspective of how to successfully lead complex teams and build a culture of excellence. The presentation will be made through the lens of life onboard a submarine and provide the audience with several vignettes, to include extensive shipyard maintenance, crew conduct, arctic operations, hurricane sorties, shallow water operations, and overseas deployments. These vignettes will focus on my submarine experiences, including command of a submarine, and how these lessons may apply or translate to leading other technical or engineering teams.

Title: Science Anecdotes of a Serial Entrepreneur
Abstract: Scientists study nature to determine how it works. I see the world, our everyday world, through the lens of science. In this lecture I recount several anecdotes about how science, often underclassmen level science, has solved problems or led to inventions in my businesses. I will discuss how stoichiometry (gen chem), statistical mechanics (gen chem), and conformational changes (o chem) affects food processing. I’ll show how simple electron pushing (o chem) led to a solution to antibiotic resistance. I’ll demonstrate how using solubility constants (gen chem) mitigated an acid-base (gen chem) problem that is leading to a novel prevention for a CDC urgent priority disease. And finally, I’ll demonstrate a simple method we all can use to trap carbon from the atmosphere, then sequester it forever back into the ground.

Title: Visualization study of quantum fluid dynamics in superfluid 4He
Abstract: When liquid 4He is cooled to below about 2.17 K, it enters the so-called superfluid phase (known as He II). In this superfluid phase, He II can be regarded as a mixture of two miscible fluid components: an inviscid superfluid component and viscous normal-fluid component. This two-fluid system can exhibit fascinating quantum-fluid behaviors that are valuable for scientific and engineering applications. For instance, He II supports the most efficient heat-transfer mechanism which is called thermal counterflow; and it also allows the generation of flows with extremely high Reynolds numbers for laboratory study of the turbulence produced around airplanes and submarines. However, the lack of high-precision flow measurement tools in He II has impeded the progress in our understanding and utilizing its hydrodynamic properties. In recent years, there have been extensive efforts in developing quantitative flow visualization techniques applicable to He II. Two types of techniques based on the use of either frozen particle tracers (i.e. micron-sized frozen particles) or molecular tracers (i.e. He2* excimer molecules) have been developed. I will discuss our contributions in this field and will highlight some recent progress in imaging quantized vortices in He II. I will also discuss how our techniques can help solving practical problems in particle accelerator field.

Title: Building Coastal and Watershed Resilience in Florida and Louisiana through Comprehensive Policy and Advocacy
Abstract: EDF seeks to ensure that climate resilient and healthy communities and ecosystems along coasts and rivers can thrive with water, and are safe, equitable and prosperous places to live, work and play. EDF advocates coastwide for the integration of natural and nature-based solutions. In Florida, EDF is developing and implementing locally supported solutions that engage communities from the ground up and governments from the top down by using science based solutions. In Louisiana, EDF is shaping and advancing the implementation of a bipartisan 50-year, $50 billion Coastal Master Plan to slow land loss and secure a more resilient and sustainable Mississippi River Delta through investments in natural infrastructure. Each state can learn from one another, and our success in Louisiana for more than a decade have allowed us to bring lessons learned to other states starting to tackle the same issues such as Florida. This presentation will provide an overview of climate resilience work in both states and why it matters for future generations.
Bio: As a manager for EDF’s climate resilient coasts and watersheds strategic initiative, Rachel works to build resilience for coastal communities facing unprecedented threats from climate change.

Rachel received her BA in Marine Science from Jacksonville University in 2013 and MS in Marine Environmental Science from Nova Southeastern University. Her thesis work centered on river diversions and wetland loss in the Mississippi River Delta and their associated effects on oysters.
Title: Synthesis of Cardiotonic Steroids Oleandrin, Rhodexin B, and Beaumontoside
Abstract: Cardiotonic steroids are a broad group of natural products that vary in chemical functionality (ie., C17 heterocycles, oxygenation pattern, and glycoside) and biological activity. Two steroids of interest are oleandrin and beaumontoside. Oleandrin is currently obtained through extraction from Nerium oleander and beaumontoside is not commercially available, but similar in structure to oleandrin providing potential as a therapeutic. Oleandrin is of interest for its anti-viral properties including the treatment of flu like symptoms and reducing SARS-CoV-2 levels by 3000-fold in golden hamsters. Our group is particularly interested in oleandrin’s use in treating Alzheimer’s disease using its ability to cross the blood brain barrier and reducing cellular prion protein levels. We developed the first synthesis of oleandrin and beaumontoside for therapeutic investigation and accessibility through synthetic means. Future studies will allow for derivatives to be synthesized in hopes of a suitable treatment for Alzheimer’s disease.
