Examining the Dynamics of Glucose Regulation

Dr. Mike Roper | Florida State University

Professor James Landers

ABSTRACT

Islets of Langerhans are the endocrine portion of the pancreas responsible for maintaining glucose homeostasis via the regulated secretion of numerous hormones, most notably insulin and glucagon. Defects in the secretion of these hormones are associated with a number of metabolic diseases, including diabetes and the metabolic syndrome. The ability to measure these glucose-regulating peptides with high time resolution and sensitivity is necessary to fully resolve the secretion dynamics of these factors and to understand how they change at various disease stages.

In this talk, a number of analytical strategies our group has developed which enable monitoring of secretion with high time resolution will be discussed. These assays include multi-color electrophoretic affinity assays, electrochromatographic separations for small molecule transmitters, and fluorescence anisotropy immunoassays. A number of these assays have been integrated into microfluidic systems to enable monitoring of secretions as a function of time. Select applications of these devices will also be discussed including how groups of islets can coordinate their secretion in vivo into pulses that are necessary for proper glucose utilization.

Electrochemical Energy Storage through Ligand-Based Charge Manipulation

Dr. Mitch Anstey | Davidson College

Professor Charlie Machan

ABSTRACT

Public and private investments in energy storage have created a 100 billion dollar industry, and this industry is now converging on grid-scale applications due to the urgent need for resource conservation and our ever-increasing global demand for energy. Redox flow batteries (RFBs) are one method for grid-scale energy storage, being used for peak-shaving and renewable energy incorporation into the grid. Our lab has been using molecular structure as one method to influence electrolyte performance metrics such as Coulombic efficiency, charge-recharge cycling, and voltage window. This talk will describe the work in our lab that focuses on molecular design to address these specific issues in nonaqueous redox flow battery electrolytes.
