UW-Eau Claire's "Ask a Scientist" series will continue Jan. 15 with a presentation titled "Graphene" by Dr. Marc McEllistrem, academic program director of the Materials Science Center and associate professor of chemistry at UW-Eau Claire. The presentation will begin at 7 p.m. at the Acoustic Café in downtown Eau Claire. McEllistrem will discuss graphene, a new "wonder material" made out of a single layer of carbon atoms. It was first prepared in 2004, and its synthesis won the 2010 Nobel Prize in physics. Graphene is very strong, light and nearly transparent, and is an excellent conductor of heat and electricity. It has many potential applications, including the design of new integrated circuits, solar cells, filter membranes and coolants. The series will continue at 7 p.m. Feb. 19 with a presentation titled "Astrophotography" by Ed Henry of the Chippewa Valley Astronomical Society.
