Title: Carbon-based nanostructures derived from fullerenes at extreme pressure

Time: 9:00 - 10:00 AM, Friday, September 8, 2017

Place: Conference room 410, HPSTAR (Shanghai)

Host: Ho-Kwang Mao

Abstract

Since the discovery of fullerene C60 in 1985 followed by synthesis of other molecular forms of carbon – e.g., nanotubes and graphene - these intrinsically nanostructured systems have attracted the attention of the scientific community. A rich assortment of outstanding properties (ultra-hardness and stiffness, very high current density limits and charge carrier mobility, etc.) these materials exhibit makes them very promising for design of advanced materials for demanding applications ranging from photovoltaics, drug delivery and molecular sensors to reinforcement constituents in composites. Intermolecular interaction in fullerenes is governed by weak Van der Waals forces thus high pressure has been used as a suitable parameter to tune their physical properties and to create new carbon-based nanostructural compounds. In this talk we review our results on high pressure studies of fullerenes and fullerene-based compounds: from fullerene polymers to composite systems based on nanostructured graphene phase synthesized from fullerene precursors.

Biography of the Speaker:





Prof. Alex Soldatov focuses his research on synthesis and characterization of novel carbon-based materials and disordered systems from nanostructured carbon precursors (fullerenes, nanotubes, graphene) using high pressure and high temperature. He has background and expertise in low temperature and high pressure experiment and actively uses synchrotron and  neutron spallation sources in his research. He received his MS in engineering physics from Kharkov Polytechnic University, Ukraine in 1984 and PhD in low temperature physics from the Institute for Low Temperature Physics & Engineering, Ukrainian Academy of Sciences in 1995. Thereafter he took during 1995-99 postdoc positions in Umea university, Sweden, University of Sussex, UK and Research Centre Karlsruhe, Germany before joining Prof. Silvera group at the Department of Physics, Harvard university as a research associate in 1999. In 2002 he moved back to Europe to take a full faculty position at Dept. of Applied Physics and Mechanical Engineering, Lulea university of technology, Sweden and he is also affiliated with the Dept. of Physics, Harvard.  

Prof. Soldatov is recipient of Shubnikov Prize for research on thermal properties of Hydrogens and low temperatures. He was Royal Society/NATO visiting scholar at University of Sussex and was awarded number of times visiting professor scholarships in Lyon and Nancy university and Karlsruhe Institute of Technology. His publication record includes Science, Nano Letters, Nanoscale, PRL, PRB, etc. He is regularly invited to speak at major international conferences in the field.

Prof. Soldatov served several times as European High Pressure Research Group (EHPRG) Committee member and since 2015 he is elected member of the Executive Committee of the AIRAPT. He is a member of the Swedish Universities Reference/Advisory Group on MAX IV Synchrotron Radiation Facility in Sweden

The other areas of Prof. Soldatov research interest include molecular electronics devices, sensors, quantum phenomena in molecular nanostructures, single molecule spectroscopy, tribo-chemistry/physics.
