先进能源材料学术报告通知

 

In this talk, I tend to show that very special properties or new discoveries are generated via capability to manage two completely opposite elements or phenomenon to co-exist at small scale in one system. These can be exampled from a wide range of scientific problems. Superconductivity and magnetism are antagonistic phenomena but when these are manipulated to co-exist at lattice scale a very strong pinning force is resulted to pin the magnetic fluxes, leading to high field performance of the superconductor for applications. Co-existence of carbon modified surface and untouched interior at nanoscale leads to a breakthrough in high field critical current density of MgB₂ superconductors. Co-existence of phonon glass and electron crystal in thermoelectric materials achieved by multi-scale scattering resulted in an ideal state for increasing figure of merit to effectively covert waste heat to electricity. Combination of active and inactive materials in energy storage system is the best strategy to ensure the electrochemical reactivity and structural integrity. A coexistence of body insulator and surface gapless conductor has led to the discovery of a completely new class of material: topological insulator with extraordinary properties.

Shi Xue Dou is Professor and Director of the Institute for Superconducting and Electronic Materials (ISEM) at UOW. He received his PhD in chemistry in 1984 at Dalhousie University, Canada. He was elected as a Fellow of the Australian Academy of Technological Science and Engineering in 1994. He was awarded a DSc by the University of New South Wales in 1998, three Australian Professorial Fellowship by Australian Research Council through 1993 to 2012, the Australian Government’s Centenary Medal in 2003, Vice-Chancellors Senior Excellence Award in 2008, Vice-Chancellor Outstanding Partnership Award in 2012. His publications attracted 14000+ citations with a h-index >53. He has led more than 50 ARC competitive projects as a lead chief investigator. He is specialized in energy and superconductor materials. He is program leader for Automotive CRC 2020. He has supervised 65 PhD students and more than 50 postdoctoral and visiting fellows who are widely spread across five continents. They have made significant contributions in their fields and established themselves as research leaders on their own right.

There is tremendous worldwide interest in nanostructured materials because their small size and special properties. The Energy Materials Research Program at the Institute for Superconducting and Electronic Materials, the University of Wollongong has been focused on the synthesis, characterization, and applications of functional nanomaterials, including nanoparticles, nanotubes, nanowires, nanoporous materials, and nanocomposites for clean energy applications such as lithium ion batteries, supercapacitors, hydrogen storage and fuel cells. This talk will highlight the recent development of new approaches to study the relationships between the structure and the physical, chemical, and electrochemical properties of nanostructured materials for lithium ion batteries.

Prof. Hua Kun Liu is a leader of energy materials research program at the Institute for Superconducting and Electronic Materials, University of Wollongong, Australia. The energy materials research group has grown from one PhD student in 1994 to 30 postgraduate students and 10 full time staff and a number of visiting fellows. She has been awarded the ARC Australian Professorial Fellowships in last 17 years (1994-1998, 1999-2003, 2003-2005 and 2006-2010), the Vice-Chancellor’s Research Excellence Award for Senior Researcers in 2013. She has supervised 50 PhD students to completion. She has pblished 500 refereed journal papers, cited 13000 times, H-index = 52, 1 USA patent and 10 Australian Innovation Provisional Patents. Her research has been focused on clean energy materials. The research topics cover the materials science and engineering, and electrochemistry and applications. Her group has developed numerous advanced materials and novel technologies for use in lithium batteries, supercapacitors, fuel cells and hydrogen storage.
