Dr. Jung-Fu Lin, professor of the University of Texas at Austin, paid a visit to ISSP on July 9th. He was warmly welcomed by ISSP co-director Prof. Zhi Zeng and director of CEMEE Dr. Xiaojia Chen. In the evening of 9th, he gave a lecture on "Transition Metal Compounds in Extreme Environments".

Dr. Lin discussed about recent results obtained on transition metal compounds on mixed-valence magnetite (Fe3O4), the 122 iron pnictide series and two dimensional molybdenum disulfide (MoS2). Their electronic, magnetic and structural properties under high pressure and low temperatures were discussed and employed to highlight recent technical advances coupling diamond anvil cells with synchrotron-based inelastic X-ray scattering and laser spectroscopy. Particularly, new insights on the phonon dispersion curves, phonon density of states, electronic structures such as its spin and valence states, elasticity, metallization and band gaps of TM compounds were also discussed. The talk ended with Dr. Lin addressing some current implications found in materials science and condensed matter physics as well as future challenges and research opportunities.

After the lecture, Dr. Xiaojia Chen expressed his thanks to Dr. Lin for his visit and hoped to cooperate with each other in the near future.
