Conference Speakers

Keynote Speakers

Prof. John W. Sheffield

Purdue University, USA

Dr. John W. Sheffield, joined Purdue University in January 2015.  He holds the title of Professor Emeritus of Mechanical and Aerospace Engineering from Missouri University of Science and Technology. Dr. Sheffield has a broad base of experience in energy technologies.  He has served as one of the founding associate directors at the United Nations Industrial Development Organization - International Centre for Hydrogen Energy Technologies (UNIDO-ICHET) during their first two years of operation in 2005-2006. He also served as the Associate Director of the National University Transportation Center at Missouri S&T. For more than forty years, he has served as an editor of the International Journal of Hydrogen Energy.  In August 2014, he completed a two-year assignment as a principal consultant at DNV GL - Energy supporting the evaluation, measurement and verification of energy efficiency programs and the response to the U.S. DOE Uniform Methods Project Protocol review of compressed air systems. In August 2015, he completed a 7-week National Science Foundation Innovation Corps program as an industrial mentor for a potential startup company based on the manufacturing of bio-inspired bipolar plates for PEM fuel cells. On 1 March 2019, he became the President of the International Association for Hydrogen Energy, having previously served as the Executive Vice President. He has also served as a part-time Professor at Xi’an Jiaotong University in Xi'an, China working in the summers with the School of Energy and Power Engineering on hydrogen energy technologies from 2019-2021 and teaching in the annual International Summer School offered by the State Key Laboratory of Multiphase Flow in Power Engineering.


Dr. Lifeng Liu

International Iberian Nanotechnology Laboratory, Portugal

Lifeng Liu is currently the Leader of the Nanomaterials for Energy Storage and Conversion (NESC) group at INL. Lifeng Liu has a PhD degree in Condensed Matter Physics from Chinese Academy of Sciences and did his post-doctoral work at Max Planck Institute of Microstructure Physics during 2007-2009. Before joining INL in 2011, Dr. Liu was a staff scientist and group leader at Max-Planck Institute of Microstructure Physics. He is Associate Editor of Science Letters Journal, and Editorial Board Member of Advances in Nano Research, Journal of Nanomaterials Science, and Science Advances Today.


Dr. George Avgouropoulos

University of Patras, Greece

Dr. George Avgouropoulos graduated from the University of Patras with a diploma in Chemical Engineering (1997). Post graduate studies were carried out in Chemical Engineering Department of University of Patras in collaboration with Institute of Chemical Engineering and High Temperature Chemical Processes (FORTH/ICE-HT), under the supervision of Prof. Verykios and Research Director Dr. Ioannides, respectively. He received a MSc diploma in Energy and Environment (2003) and a PhD diploma in Chemical Engineering (2003) from University of Patras. Since July 2003 he works as a research associate at FORTH/ICE-HT. In June 2010 he was elected a Lecturer at the Materials Science Department of University of Patras in the field of “Materials engineering in microphase-nanophase or/and molecular or/and biomolecular materials or/and devices – experimental direction”. In the midterm he was a postdoctoral fellow of National Fellowships Foundation (2006-2007), assistant professor at the Technological Educational Institution of Kalamata in Greece (2005-2010) and fixed term Lecturer at the Materials Science Department (2008 – today). He has co-authored 36 research papers and has received more than 1600 citations. He has presented more than 50 research papers in scientific conferences, while he co-holds two international patents.

In addition, three of his papers have been recognised as "Top-50 most cited articles" by Elsevier. He has co-edited a book in RSC Catalysis Series. He has participated as senior researcher in several European projects dealing with catalysis and fuel cell. He has developed research activities in the development (synthesis and characterization) of nanostructured catalysts (mainly Cu-Ce mixed oxides and Cu-Mn spinel oxides, as well as precious metal-based catalysts such as Au/Fe2O3, Au/CeO2, Pt/CeO2 Pt/Al2O3, and carbon-based materials) for application in hydrogen technologies (methanol fuel processors and PEM fuel cells). Recent research activities focus on the development (reaction engineering, synthesis-characterization-testing of materials) of a methanol-fuelled power unit based on a methanol reformer and a high temperature PEM fuel cell. His expertise spreads across a variety of analytical characterization techniques required from the nature of nanostructured materials focusing on collection of information with respect to the morphology, microstructure, phase distribution, etc. These include N2 adsorption, X-ray powder diffraction (XRD), electron microscopy (TEM, SEM), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA) and temperature-programmed methods (TPR, TPD), isotopic measurements (SSITKA).
