Session C-2 Aug.29

This is the second day of C-2 session in IUMRS-ICAM2017. A first paper in the morning was cancelled. Since more than 30 audiences were waiting in the room, Prof. Bruno Ameduri (CNRS) volunteered to entertain these audiences by his magic show. Prof. Bruno Ameduri is a famous chemist in the area of fluoropolymers and is also well known as CliniClown visiting sick children in hospitals of Montpellier and abroad. He showed the difference in molecular weight synthesized by free radical polymerization and controlled radical polymerization through the length change of three different ropes by his magic! All audiences understand the concept of molecular weight distribution of polymer.

Symposium:B-6 Aug.29

Advances in Functions and Reliability of Ceramics and Glasses Based on Structural Formation

Solid oxide fuel cell, environmental purification filters, wind power generation and solar cells are promising advanced systems to make a contribution to energy and environmental issues. In these systems, advanced ceramics and glasses are quite important as key materials, and further improvement of the materials functions and reliability is needed. This session was planned to discuss various possibilities for the sudden rise in advanced ceramics and glasses extensively from the viewpoint of structural formation.

This session was held from Aug. 28(MON) to Aug. 30(WED), 2017, in Kyoto Univ. and had 10 invited talks, 13 oral presentations, and 24 poster presentations. The speakers came from China, Taiwan, Korea, Thailand,Mexico and Japan. There were 20 or more attendees gave enthusiastic discussion for each oral presentation from various point of view (Fig.1). Especially, on the 2nd day, Prof. Soo Wohn Lee, President of IUMRS participated this session all day and gave his comments to many presentations (Fig.2).

To advance our friendship between the speakers in this session, we went for dinner as the session banquet in the evening of the 2nd day. We enjoyed Japanese Sake and fish Hamo (Conger myriaster) in a traditional restaurant, and have a good time to know each other. We promised to meet again in the next conference when we went back our accommodations.

Finally, all the organizers greatly expressed their gratitude to all speakers of this session, and also organizing committees of IUMRS-ICAM2017.

Symposium B-2 : Advanced thin film materials for future electron device and sensor

Mesostructured SrTiO3/BaTiO3 Hybrid Films by Surfactant-Templated Sol-Gel Pathway with Robust Ferroelectricity

M. B. Zakaria1 of NIMS, Tsukuba, Japan, and his colleagues reported an unique method to make mesostructured SrTiO3/BaTiO3 Hybrid Films for stable higher dielectric capacitor application. At first, he made a mesostructured SrTiO3. Due to the missing volume of the SrTiO3, the substrate showed a concave structure. Then BaTiO3 goes into mesostructed SrTiO3 to form a mesostructured SrTiO3/BaTiO3 composite. Here a large number of strains can be created in the composite film, thereby leading to dramatic enhancement of ferroelectric property. Practically
mesostructured STO/BTO composite films showed the highest dielectric constant among all reported STO/BTO composites.

Symposium A-9: Materials for living – environment / energy / medicine –

Materials Design for the Biomedical Imaging in OTN Near Infrared Transparent Optical Window

Kohei Soga of Tokyo University of Science, Japan, gave an excellent keynote talk in the oral session of Symposium A-9 on August 28. He explained that “Transparency” is one of the hard challenges for the developer of optical biomedical imaging techniques and optical loss is basically caused by scattering and absorption. In order to avoid scattering, he used over-1000 nm near-infrared light. With a combination of an InGaAs CCD camera and near-infrared fluorescent materials, his group obtained clear image of biomedical imaging. Soga’s group developed both imaging systems and fluorescent materials. He developed organic dyes, quantum dots, graphene related materials, and rare-earth doped ceramics as near-infrared fluorescent materials. The rare-earth doped ceramics can have multiple functions; their application could be therapy and diagnosis at the same time. He also suggested that over-2000 nm near-infrared wavelength region could be used for biomedical imaging. Over 20 participants attended the keynote.

Before the keynote, Lei Miao of Guilin University of Electronic Technology, China, gave an invited lecture of “Fabrication and Thermoelectric Properties of Flexible Films Based on Telluride Nanowires.” Her films could be used for portable/wearable electronic devices.

On this day Symposium A-9 had sessions for three oral papers and 39 poster papers with active discussion.

Symposium A-5: Session SULPHIDES / Aug. 28

Chairmans : David Berthebaud and Kanishka Biswas.

The sulphide session was opened by invited speakers Dr. Emmanuel Guilmeau from CNRS CRISMAT, Caen, France on new complex sulphides. He presented latest development on advanced synthesis and characterization of p-type sulphides in his group. These results included original characterization of this material through Mossbauer spectroscopy and neutron diffraction. He was followed by another invited talk from Pr. Anthony Powell, Reading University, UK, who as well presented interesting development on sulphides materials. Those both talks showed that this field is very active. Third invited talk of this session was Pr. Kanishka Biswas from JNCASR Bangalore; his talk showed latest results and comprehensive study of chalcogenides materials with ultra-low thermal conductivity. Four more contributed talks followed this introduction by invited speakers. Dr. Tristan Barbier from CRISMAT, presented new synthesis method to produce pure cubanite, a copper-based mineral sulphide through microwave irradiation. This technic allows synthesis of homogenous sample in less than a minute. It was followed by a talk of Dr. Hongyao XIE from Wuhan University who also presented original synthesis method to produce copper based sulphide materials. He successfully synthesized chalcopyrite through rapid thermal expansion. An additional talk from Wuhan University was given by Dr. Dongwang YANG on the synthesis and thermoelectric properties of dicopper chalcogenides. Finally, the last talk before closing this interesting session was given by Dr. Hiroki NAGAI from Tohoku University who presented his work on the exploration of new sulphide compounds know as olivine-sulfides.


Symposium B-3: Organic and Molecular Electronics

Symposium B-3: Organic and Molecular Electronics Invited talks and poster presentations for an award.

We had three invited talks and three contributing presentations on the first day of the conference. About thirty researchers joined the session. Toshinari Matsushima from Kyushu University reported organic-inorganic perovskite materials as the semiconductor in field-effect transistors showing excellent carrier transport. Matsushima and co-authors demonstrate a record hole mobility of up to 15 cm2 V-1 s-1 at room temperature along with negligible hysteresis and good bias stability in p-channel transistors with a spin-coated semiconductor of the perovskite (C6H5C2H4NH3)2SnI4 by solving the aforementioned issues through surface treatment of the substrate with a self-assembled monolayer containing ammonium iodide terminal groups in combination with the adoption of atop-contact/top-gate structure with MoOx hole injection layers. Masatoshi Sakai proposed solvent-free printing. Hisao Ishii reported precise measurement of electronic structures. Poster session was also held. Many students reported their study with a great vitality.
