attracting global participant’s intent on sharing, exchanging and exploring new
avenues of Chemistry and related research and latest developments. The event
will have highly
cited class plenary speakers, established keynote speakers, Invited speakers
and fresh contributed speakers.

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.
