Frontiers in Chemical Physics Symposium: Nancy Levinger

[Schechter, Robert K.]

Hello,

The Chemical Physics program is hosting Dr. Nancy Levinger from the Colorado State University to give lectures as part of the Frontiers in Chemical Physics Symposium lecture series on Wednesday April 4th and Friday April 6th. The topics for Dr. Levinger's talks are below. The lectures will be held in 2015 McPherson Laboratory at 9:35am April 4th and April 6th  all are welcome to attend.

April 4, 2018 -Water on the nanoscale - when water is not water

Abstract: Many studies have revealed subtle details about properties of water in bulk solutions.  However, nature presents many examples of water limited to nanoscopic proportions.  In these environments, characteristics can differ from bulk properties.  Using a range of experimental methods, we have explored the impact of nanoconfinenment on water in reverse micelles.  We have explored bulk solution properties, such as pH and ionic strength, as well as molecular properties, such as water motion and exchange with other species, on the nanoscale.  These results tie together to present a comprehensive picture of how water confined on the nanoscale differs from bulk solution and the implications for processes occurring in these types of environments.

April 6, 2018 - Sweet confinement: glucose and other carbohydrates in reverse micelles

Abstract: When introduced to reverse micelles, carbohydrates such as glucose, sorbitol, and trehalose result in smaller particles than those prepared with only water. This observation led us to explore the nature of carbohydrates in reverse micelles - how the environment impacts the molecules and how the molecules impact the environment. Through a range of measurements we are developing a model to explain the reverse micelle size variations.  At the same time, we explore the impact of the reverse micelle nanoconfined environment the carbohydrates, where we measure dramatic slowing of chemical exchange rates between carbohydrates hydroxyl groups and water.
