The interim chair of the physics department at Temple University in Philadelphia, Pennsylvania, Xiaoxing Xi, is a naturalized U.S. citizen who has lived and worked in the United States since 1989. He is among the world's leading experts on superconducting thin films, which carry electricity without resistance at very low temperatures. But now he stood charged with sharing designs for a proprietary technology with China and faced 80 years in prison and a $1 million fine. Charges were later dropped after experts submitted affidavits in Xi's defense. Advocates allege that Xi is among a growing number of scientists who have been targeted improperly in a Justice Department campaign against economic spying and trade secrets theft.
