Graphene nanoribbons (GNRs) are an important graphene family of materials because of their finite band-gaps, where the band-gaps can be varied depending on the width of GNRs. Recently, we found a novel method to prepare GNRs from multiwall carbon nanotubes (MWCNTs) by “extracting” inner tubes in solution phase. I will present some unique structural and electronic properties of such GNRs synthesized from MWCNTs.  Furthermore, I will talk about the fabrication and characterization of, what we all, graphene/h-BN (hexagonal boron nitride) hybrid (atomically) thin films. These graphene-based new materials will surely play a crucial role in future nano-electronics and related materials science.

Hisanori SHINOHARA:

Hisanori Shinohara received his B.Sc. in 1977 from Shinshu University and his Ph.D. from Kyoto University in 1983 in Chemical Physics. He joined the research group of Prof. Nishi as a research associate of Institute for Molecular Science (IMS) at Okazaki in 1979 where he made some pioneering works on laser spectroscopy of supersonic jet-cooled molecular clusters of water, ammonia, benzene and so on. He then became an associate professor of Chemistry at Mie University in 1988. During this period he started fullerenes and metallofullerenes works in addition to molecular microclusters. He came to Nagoya University in 1993 as a full professor in Chemistry. He is the recipient of the Japan Mass Spectrometry prize (1991), the Japan Metal Society prize (1994), the Japan IBM Science prize (1996), Molecular Science Forum Lectureship at Chinese Academy of Science (2002), Ishikawa Carbon Prize (2006), Japan Chemical Society Award (2010 ), Chunich Cultural Award (2011), 2012 Visiting Lectureship of the Chemistry Research Promotion Center [The National Science Council (NSC) of Taiwan]). He is widely known for his achievement on the production and characterization of endohedral metallofullerenes and novel carbon nanotube materials. His research team has been produced, purified and characterized more than 70 endohedral metallofullerenes. His research team recently synthesized the first single-wall carbon nanotubes with metallofullerenes encapsulated inside the nanotubes, which was reported in Phys.Rev.Lett. and Science in 2000 and Nature in 2002. Totally, he has published over 380 original and peer-reviewed scientific papers including approximately 200 in the top physics and chemistry journals , and more than 50 review papers in journals and books. He has also presented a lot of invited lectures/seminars and conference talks. He is also the members of Japan Chemical Society, Japan Physical Society, Japan Mass Spectrometry Society, Materials Research Society (U.S.A.), Electrochemical Society (U.S.A.), American Association for the Advancement of Science (U.S.A.), and serves as referees in many international journals in physics, chemistry, materials science and engineering.
