IES High-pressure Mineral Physics Laboratory Research Published in PNAS (Proceedings of the National Academy of Sciences, USA)

Dr. Wen-Pin Hsieh of the IES high-pressure mineral physics laboratory has combined ultrafast optics with diamond cell techniques to measure the thermal conductivity of ferropericlase at high pressures. His team found that the thermal conductivity of iron-rich ferropericlase drops significantly across spin transition of iron, resulting in an enhanced iron substitution effect in the low-spin iron-rich ferropericlase. Combined with prior results and data modeling, they demonstrated that iron plays critical roles in affecting the thermal conductivity, thermo-chemical structures, cooling rate, and geodynamics in the lower mantle. These results further help better understand the thermal history of ultra-low velocity zones at the bottom of the mantle: if these regions are hot and enriched in iron, their exceptionally low thermal conductivity may delay their cooling and keep them substantially hotter than their surroundings. The international research team includes Drs. Wen-Pin Hsieh and Frédéric Deschamps of IES, Prof. Jung-Fu Lin of University of Texas at Austin, and Dr. Takuo Okuchi of Okayama University. [Details]

IES Director Academician Sun-Lin Chung was elected 2018 TWAS Fellow

The World Academy of Sciences (TWAS) announced the election of three Academia Sinica Academicians among its 2018 list of 55 new TWAS Fellows on January 26 in Trieste, Italy. IES Director Academician Sun-Lin Chung was elected to the area of Astronomy, Space and Earth Sciences among only 5 new TWAS Fellows. Academician Chung has made significant contribution to our understanding of continental tectonics and magma generation based on his outstanding studies in High Asia (from Tibet to Iran) and neighboring regions. He has also received the TWAS Prize in Earth Sciences in 2014. [Details]

IES Associate Research Fellow Dr. Kuo-Lung Wang Receives 2018 Academia Sinica Career Development Award

IES Associate Research Fellow Dr. Kuo-Lung Wang's proposal "Tracking ancient mantle evolution: geochemical investigation of ophiolites and mantle xenoliths in the Aldan Shield, Siberian Craton" has received the 2018 Academia Sinica Career Development Award. The CDA is awarded for five years (2018-2022). Current IES recipients of CDA includes Research Fellow Dr. Ya-Ju Hsu for "Modeling of earthquake-cycle slip and slow-moving landslides using the rate-and-state friction law (2016-2020)" and Assistant Research Fellow Dr. Wen-Pin Hsieh for "Thermal conductivity and elastic property of deep Earth materials under extreme pressure-temperature conditions (2017-2021)".
