Cold Plasmas: A Hot New Technology at Next Clarkson University Science Cafe

"Cold Plasmas: A Hot New Technology!" will be presented by Clarkson University Assistant Professor of Chemical and Biomolecular Engineering Selma Mededovic-Thagard at the next Science Café on Tuesday, April 8, at 7:15 p.m. in the Park View Common Room, above the Blackbird Cafe, 107 Main St. in Canton, N.Y., and on Wednesday, April 9, at 7:15 p.m. in the Potsdam Civic Center Community Room in Potsdam, N.Y.

Selma Mededovic-ThagardPlasmas, the “fourth state of matter,” make up 99 percent of visible matter in the universe and are extremely hot. On Earth, plasmas occur naturally within lightning, the ionosphere and in the auroras (Northern and Southern Lights). Plasmas can also be made in a laboratory. You probably heard of plasma TV, fluorescent light bulbs and neon signs, but did you know that plasmas can also be used to decontaminate drinking water, convert graphite into diamond, coagulate blood, and even sterilize teeth?

Join Mededovic-Thagard for a fascinating discussion of plasmas and their chemical processing, and their application in medicine, chemistry and engineering.

Science Cafes bring together engineers, scientists and townspeople in a relaxed, informal setting, such as coffeehouses and pubs. The speaker makes a short presentation about a topic in his or her field, and then opens up the floor to discussion.
