Senior Wins Award for Presenting Talk on New Undergraduate Experiment

By Betty Gabrielli

 

APRIL 11, 2000--A talk on a new experiment she helped develop for the biochemistry laboratory last summer has won Nanette Lacuesta, a senior from Celina, Ohio, an award and a cash prize sponsored by the Cleveland Section of the American Chemical Society (ACS).

A biology major and chemistry minor, Lacuesta gave her talk at the annual Meeting-in-Miniature of the Cleveland section of the ACS held at Baldwin Wallace College last month.

"Students are doing the experiment for the first time this semester," says Norman Craig, Biggs Professor in the Sciences, who helped develop the experiment for class use with William Fuchsman, professor of chemistry. William Marton, the college's machinist, and William Mohler, the College's electronic technician, helped make new apparatus for the experiment.

Students are making use of the chemistry department's new Nicolet Fourier transform Raman/infrared spectrometer to study temperature-dependent changes that occur in the hydrocarbon interior of phospholipid membranes dispersed in water. The dispersions are models of biological cell membranes.

"We believe this is the first example of such an experiment being done in undergraduate biochemistry laboratories," Craig says. "Until now, such studies have been confined to research investigations."
