ROCK HILL, SOUTH CAROLINA — Four Winthrop University chemistry and biochemistry faculty
members were awarded grants this summer that will provide opportunities for more undergraduate
research on energy, cells and molecules.
Chemistry Professor Jay Hanna was approved for a $70,000 grant from the American Chemical Society Board of Directors that will last through the summer of 2020.
Reviewers noted that Hanna has a strong track record of engaging undergraduates in
meaningful, publishable research over an extended period of time and has mentored
several students who have advanced to graduate programs. Also, energy data from preliminary
experiments conducted by Hanna and his students were very strong and convincing in
what is a new area of research for him, said Pat Owens, chair of the Department of Chemistry, Physics, Geology & the Environment.
Three other faculty members — Aaron Hartel, Cliff Harris and Nick Grossoehme — had proposals awarded in South Carolina for up to $10,000 for the next academic
year. The State EPSCoR/IDEA Office, which stands for Established Program to Stimulate Competitive Research (EPSCoR)
and Institutional Development Awards (IDeA), is a federal-state-university partnership
designed to increase research support for states such as South Carolina who have historically
received low levels of federal research and development funds. The office gave out
only 11 grants statewide in this year's cycle.
Recipients of this funding will have their students receive stipends, and they will
be able to attend the 2018 SC EPSCoR/IDeAstate conference to present their research results and experiences.
Here are the projects the professors will be working on:
*Jay Hanna — He said that most of the products we take for granted in society — medicines, plastics,
pesticides, dyes and even cosmetics — require energy, often generated by burning fossil
fuels, as an integral part of the manufacturing process. "The objective of our research
is to discover ways to use visible light as an energy source for some of these chemical
reactions. The ultimate goal would be to develop the use of ordinary light bulbs,
or better yet, sunlight, as a practical energy source for the fabrication of these
substances; in essence, a kind of ˜artificial photosynthesis' approach to chemical
transformations." In addition, Hanna said, an understanding of the fundamental science
behind this approach may lead to new chemical transformations that are not currently
possible.
*Nick Grossoehme - Iron plays a very important role for nearly all living organisms; however, it is
also toxic if it is allowed to accumulate inside cells. Consequently, cells have evolved
ways of controlling the amount of iron to ensure that there is enough to be healthy
but not too much to be lethal. "Streptococcus pneumonia is a bacteria that naturally
lives in our nose and throat: it can lead to disease (pneumonia, strep throat and
meningitis) when it migrates into other tissues," Grossoehme said. "Curiously, the
way that this bacteria controls the levels of iron is not known. A better understanding
of how this bacteria controls iron could lead to the development of better antibiotics."
The research that is funded by this grant will allow Grossoehme and his students to
investigate one possible iron control system.
*Clifton Harris — His work aims to create special coatings that can absorb the sun's energy and use
that energy to break the chemical bonds in water, which are hydrogen-oxygen bonds.
"By breaking these bonds, we can decompose water into its base elements, hydrogen
gas and oxygen gas," Harris said. "The significance of this is that hydrogen gas is
a very energy-rich fuel source that produces zero harmful emissions after combustion.
So, in essence, we are converting sunlight to fuel."
*Aaron Hartel — He and his students will develop new chemical transformations that enable chemists
to build larger molecules by combining smaller, simpler ones. "These novel reactions
form critical carbon-carbon bonds and have potential application in the development
and production of pharmaceuticals," Hartel said.
