By enhancing the ability of hydrogen to accumulate in high densities and integrating it with hydrogen’s other functions, we intend to synthesize new hydrogen clusters that exceed conventional limits on hydrogen density. This will permit the induction of hydrogen’s high-order functionalities. By enabling the electron orbits of hydrogen that are hidden in the low-energy region of the valence band to be raised to near the Fermi surface, as well as by inducing the high-speed migration and rotation of hydrogen clusters, we aim to synthesize super-functional materials such as hydride superconductors and superionic conductors. Research will be conducted in collaboration with researchers across the whole field.
We aim to induce the high-order functions of hydrogen by creating unique heterointerfaces. At the interfaces,
hydrogen is arranged with high accuracy by controlling local stresses and band bending. By designing novel interfacial electronic states, we intend to develop hydride electronics, efficient photovoltaics, and high-strength steel. We are eager to collaborate with researchers across the whole field.
By enhancing the high-speed migration capability of hydrogen and integrating it with hydrogen’s other functions,
we intend to enhance the transport phenomena of hydrogen in macromolecular materials and metals considerably.
This, in turn, will allow us to induce the high-order functions of hydrogen by controlling proton conduction and
multi-electron transfer processes inside materials and at their interfaces. We aim to design next-generation devices
for energy conversion and storage. Research will be conducted in collaboration with researchers across the whole
field.
By enhancing the high-speed migration capability of hydrogen and integrating it with hydrogen’s other functions,
we can achieve significantly strengthened coupling of electrons and various hydrogen species that transfer locally
and at high speed, as well as enhance the superionic conductivity of hydrides. This, in turn, will induce the highorder
functions of hydrogen. By controlling these functions inside organic materials, inorganic materials, and
biomaterials, as well as at their heterointerfaces, novel devices can be developed. Research will be conducted in
collaboration with researchers across the whole field.
By enhancing the ability of hydrogen to accelerate reaction processes and by integrating this with hydrogen’s other
functions, we intend to construct reaction fields in which various hydrogen species can be effectively activated and
precisely controlled. This, in turn, will induce the high-order functions of hydrogen. By hierarchical construction of
new catalytic reaction fields that enable the generation and conversion of active hydrogen species under mild
conditions, new processes for converting hydrogen into different useful materials can be developed depending on
the hydrogen species. Research will be conducted in collaboration with researchers across the whole field.
We aim to establish cutting-edge operando measurement techniques to measure the various states of various
hydrogen species. These techniques will systematically analyze the absolute concentration distribution, atomic
arrangement, and dynamics of hydrogen, which are difficult to detect inside materials. Furthermore, by integrating
the aforementioned parameters with computed data from A01–A04 and A05–2 and establishing a hydrogen data
assimilation technique, we will make significant progress in streamlining the process of developing innovative
materials, devices, and reaction processes. Research will be conducted in collaboration with researchers across the
whole field.
By developing first-principles electronic-state calculation methods and integrating the methods with measurement
data obtained from A01–A04 and A05–1, we intend to establish a hydrogen data assimilation technique to be used
as a method based on statistical mathematics. This technique will be used to determine the absolute concentration
ratio, atomic structure, and dynamics of hydrogen inside materials with high accuracy; to elucidate the expression
mechanisms of the hydrogen functions; and to enhance the efficiency of theoretical prediction. Thus, we aim to make
significant progress toward streamlining the process of developing innovative materials, devices, and reaction
processes. We will conduct this research in collaboration with researchers across the whole research area.
