He was the Director of Center for Materials Design for 1996-2002. He retired at 2008, Professor Emeritus from Tokyo Institute of Technology. He is nominated form Thomson-Reuter as ISI Highly-Cited Researcher (2001). Now he has >730 peer-reviewed Papers, 84 Reviews, 4 Books (49 Book Chapters) & >30 Patents, and >18,000 International. Citations with h-index >68, in Google Scholars: >28,700 Citations with h-index= 78.

Being an invited plenary speaker, Dr. Masahiro YOSHIMURA is going to talk about “Why is Soft (= Green, Solution & Low-Energy) Processing of Advanced Inorganic Materials Difficult but Necessary for Sustainable Society?” A brief summary is presented here.

Modern our society has been developed with various advanced materials. Most of advanced materials, Metallurgical materials, Semiconductors, Ceramic materials and Plastics have been used in wide area of applications like structural, mechanical, chemical, electrical, electronic, optical, photonic, biological, medical, etc. Most of them except for bio-polymers & bio-minerals have never been produced via biological systems. Thus they have generally been fabricated artificially and/or industrially by so-called high-technology, where  high temperature, high pressure, vacuum, molecule, atom, ion, plasma, etc. have been used for their fabrications, then consumed huge amount of resources and energies thus exhausted  huge amounts of wastes: materials, heats and entropy. To prevent this tragedy, we must consider water-based industries.
Considering the lowering of total energy consumption, we have challenged to fabricate those advanced inorganic materials with desired shape/size/location, etc. directly in low energetic routes using aqueous solutions since 1989 when we found a method to fabricate BaTiO3 film on Ti substrate in a Ba(OH)2 solution by Hydrothermal Electrochemical[HEC] method at low temperatures of 60-200 C.  We  proposed in 1995 an innovative concept and technology, “Soft Processing” or “Soft Solution Processing,” which aims low energetic (= green, environmentally friendly) fabrication of shaped, sized, located, and oriented inorganic materials in/from solutions.  It can be regarded as one of bio-inspired processing, green processing, or eco-processing.  When we have activated/stimulated interfacial reactions locally and/or moved the reaction point dynamically, we can get patterned ceramic films directly in solution without any firing, masking nor etching.   Direct Patterning of CdS, PbS and CaWO4 on papers by Ink-Jet Reaction method. Furthermore, we have succeeded to fabricate BaTiO3 patterns on Ti by a laser beam scanning and carbon patterns on Si by plasma using a needle electrode scanning directly in solutions.  Successes in TiO2 and CeO2 patterns by Ink-Jet Deposition, where nano-particles are nucleated and grown successively on the surface of substrate thus become dense even below 300 C will be presented. Nano-structured films will be also talked. .A recent novel subject, Soft Processing for various 2D materials including Graphene and functionalized Graphene, will be introduced where we have succeeded to prepare functionalized Graphene Ink via successive processes under ambient temperature and pressure conditions.
