PHILADELPHIA (AP) — A physics professor at a Philadelphia university has pleaded not guilty to charges he gave U.S. technology secrets to China.

Temple University professor Xi Xiaoxing (shee show-shing) is an expert on superconductivity, which is the ability to conduct electricity without resistance. A superconducting thin film could be key in making computer circuits that work faster.

The 47-year-old entered his plea Thursday. He is free on $100,000 bail and surrendered his passport.

He is a naturalized U.S. citizen born in China.

Prosecutors say he schemed to provide secrest in exchange for prestigious appointments for himself.

Xi's lawyer, Peter Zeidenberg, successfully defended an Ohio woman in a Chinese spying case. Zeidenberg says Xi will be exonerated.

Xi was chairman of the university's physics department until his arrest. He remains a faculty member.
