Yiqing Chen is Research Fellow at the School of Mechanical and Manufacturing Engineering, the University of New South Wales, Australia. She has been conducting research on polishing of diamond materials since her PhD study in 2003 at The University of Sydney, and has 25 publications in this field. Her research focuses on the characterization of advanced materials and development of advanced methods for processing of difficult-to-machine materials. She has received 7 academic and research awards, including a best paper and a best presentation award in two prestigious international conferences, and has a worldwide patent in “Method and apparatus for polishing diamond and diamond composites”.   Liangchi Zhang is Scientia Professor, Professor of Mechanical Engineering and Australian Professorial Fellow at the School of Mechanical and Manufacturing Engineering, the University of New South Wales (UNSW), Australia. He is Elected Fellow of the Australian Academy of Technological Sciences and Engineering. Prior to UNSW, he has worked in the University of Cambridge, UK, National Mechnical Engineering Laboratory, MITI Japan, and the University of Sydney, Australia. His research involves both fundamentals and technological development in the interdisciplinary areas of precision and nano manufacturing such as free form microlens arrays; bio-manufacturing of prostheses such as hip joint implants; nanomechanics and nanomaterials such as nanotubes, graphene and nanocomposites; characterisation of materials such as diamond, silicon, ceramics, polymers and composites; tribology of materials such as mixed lubrication and friction and wear of nano/micro/macro-scale sliding systems; and solid mechanics and computational mechanics such as solutions to elasticity and pasticity of advanced materials and their constitutive modeling.  Liangchi Zhang has published extensively his research outcomes in over 450 publications including 5 books and many patents.The application of his technologies has led to considerable economic benefits. He is the recipient of about 30 prizes, awards, honours and distinctions including the “Distinguished Achievement Award in Machining Technology (2000)”, the “B-HERT Award for Best Research and Development Collaboration (2007)”, and the “UNSW Inventor of the Year (2011)”.
