Yoshio Bando has completed his Ph.D from Osaka University in 1975 and joined the National Institute for Materials Science (NIMS) the same year. He had been a Fellow of NIMS and a Chief Operating Officer (COO) of International Center for Materials Nanoarchitectonics (WPI-MANA) until April 2017.  He is now an Executive Advisor of MANA and Distinguished Professors both at University of Wollongong, Australia and Tianjin University, China. He has received a number of awards including the “Sacred Treasure” from the Emperor (2017), the 3rd Thomson Reuters Research Front Award (2012), the 16th Tsukuba Prize (2005), the Academic Awards from Japanese Ceramic Society (1997) and others. He is admitted as Fellows of The American Ceramic Society and The Royal Society of Chemistry. He served as Editor-in-Chief of Journal of Electron Microscopy from 2008-2012 and as Editorial Board Members of Materials Today Advances, Nano Energy, Materials Horizon, Nanotechnology, Nanomaterials and others. He has been selected as ISI Highly Cited Researchers in Materials Science in 2010, 2012, 2014, 2015 2016, 2017 and 2018.  To date he has authored more than 800 original research papers which have been cited more than 45,500 times at H-factor of 113 (Web of Science). His research concentrates on synthesis and property of novel inorganic 1D/2D nanomaterials and their in-situ TEM study.

报告摘要：

Hexagonal boron nitride (h-BN), a layered material with a regular network of BN hexagons, is a structural sister system of famous graphite. BN is highly insulating and wide-bandgap in properties, and more stable than graphite in thermology and chemistry. These make BN be a perfect sidekick of graphite nanomaterials, and enable their bright prospects in high thermal conductivity, strong ultraviolet emission, glorious thermal and chemical inertness, rubout insulation and superb lubrication. However, their insufficient production rather limited the studies and the full realization of potentials. We aim to develop new nanomaterials such as nanotubes and nanosheets in boron-carbon-nitrogen system for their applications to thermal conductive packaging as well as energy storage, based on our recently developed effective methods for the high-yield syntheses of BN nanotubes and nanosheets. In addition, we demonstrate the striking effects of tensile, compressive and bending deformation on the electrical response of BN nanotubes and nanosheets under manipulation and electrical probing in HRTEM using STM/AFM-TEM holders. And the unique mechanical property of BN nanotubes is demonstrated by in-situ TEM. We conclude here that BN nanotubes have a high potential for the applications in novel nanoscale sensors, actuators and advanced nanoelectromechanical systems (NEMS).
