Sam White, physics Ph.D. candidate at Vanderbilt University in Nashville, Tenn., presented a discussion on “Phase Transitions in VO2: Optical Properties and Applications” to more than 70 Grace College general chemistry students on November 4. His presentation was at the invitation of Dr. Chad Snyder, Grace College chair of the Department of Science and Mathematics at the Winona Lake, Ind., school.
White’s research focuses on Department of Defense funding as well as NASA funding. His studies center on the unique properties of vanadium (IV) oxide and its applications that include the protection of our U.S. and allied tank periscope operators.
In his presentation, he discussed the dangers periscope operators face from incoming enemy laser attacks that are meant to blind. In response to that threat, his research can help provide tank periscope operators a VO2 coating that will shield their eyes much like UV filters on particular sunglasses.
He also discussed how his research has applications in space technology where some types of VO2 coatings can shield many satellites from harmful radiation from the sun as well as keep their internal temperatures consistent ensuring continued operation.
