After many years of research, one comes across "Exciting Moments." These "moments" donot happen often, maybe once every few years or even every ten years. However, the "Exciting
Moments" almost make me lose track of time as I get up early in the morning, run to the lab,check out the experimental equipment, code the program, and head home. According to yourformulated hypothesis, the "thrilling moment" comes when you can prove something that noone else knows. It is the moment when you can confirm what other researchers do not know
and what only you know with your hands. Once you have tasted this moment, you cannot stop
doing research. To experience that "Exciting Moments," I spent several years steadily
preparing, acquiring new knowledge, and thinking of new experimental and analyticalmethods. Experiments do not always go well, and there are many times when I feel like myheart is about to break. However, I want to taste that "exciting moment" again, which is how
I continue my research.
Today, much information is relatively easy to obtain, and high-performance measuring
instruments and high-speed computers can be purchased. However, the data and findings fromshopping are merely information available to everyone else. To obtain data that otherresearchers have not been able to get, one must devise equipment and implement proprietarycode into the computer. Sorting out what is known and not known worldwide and developing a
research plan to obtain original data requires a high level of expertise. It requires knowledge
that allows us to understand phenomena with deeper observation and insight than anyone else.
Furthermore, it requires knowledge of different fields to enhance originality, which no otherresearcher has done. There is a fusion of knowledge in physics and chemistry within engineering.
If engineering researchers know medical, environmental studies, fisheries science, andoceanography, they can create innovations. Researchers and engineers of the future will be
required to have a high level of expertise and a broad range of knowledge.
Nagasaki University has adopted the slogan "Planetary Health" to protect the health of ourplanet. Exciting moments" can create new knowledge and contribute to creating a livable society
on a global scale. At our university, we will acquire a high level of expertise and a wide range ofknowledge, and together, we will savor the "exciting moment" and realize "Planetary Health."
faculty member of the Graduate School of Engineering; we hope it will help cooperation andfusion among fields and collaboration between industry, academia, and government.
Let us create "Exciting Moments" with us!

NUMERICAL MODEL FOR 3D STEEL MOMENT FRAMES
Most previous studies only considered the behavior of steel moment frames under unidirectional
ground motions. Additionally, the numerical models of most previous studies considered the behavior of
only beams and columns, and ignored the behavior of the panel zone of the beam column connection.
Our research proposes a novel numerical model for studying steel moment frames undermulti-directional loadings to consider the 3D elastoplastic behavior of beams and columns, as well as
panels. The proposed numerical model was validated by analyzing cruciform subassemblies of beams,
columns, and panels, and the analysis results were compared to the experimental results from previous
studies. The results of the proposed numerical model corresponded well with the respective test results
REQUIRED COLUMN OVERDESIGN FACTOR OF 3D STEEL MOMENT FRAMES
Steel moment frames are designed to ensure sufficient energy absorption capacity by achieving anentire beam-hinging collapse mechanism under severe earthquakes. Therefore, the column overdesign
factor is stipulated in seismic design codes. Since square tube columns are often used for steel structurebuildings in Japan, the two orthogonal planes of the structure are both designed as moment resisting
frames. Considering the effect of bi-direction ground motions on the steel moment frames, the specified
column overdesign factor is 1.5 or more in Japanese seismic design code. However, the required column
overdesign factor of steel moment frames is obtained from analysis results conducted underunidirectional ground motions
Our research describes the results of the earthquake response analysis of 3D steel moment frames, andpresents seismic demand for the column overdesign factor, depending on input direction and amplitudeof the ground motion and width-thickness ratio of columns, required to keep the damage below the limitof plastic deformation of square tube columns.
SEISMIC STRUCTURAL REINFORCEMENT IN DEVELOPING COUNTRIESIn Japan, retrofit method with steel brace frame for RC structure are always used. Retrofitting withsteel braced frame a lot of studs and anchor bolts are required to fix the steel frame and transmit thetensile stress of diagonal brace to the existing RC frame. However, this method needs heavy equipment
and it is difficult to use particularly in rural area, constricted area or remote island.
For seismic retrofitting in the areas mentioned above, we have been developed a new seismic
retrofitting method by using CFST (concrete-filled steel tubular) diagonal brace which act only
compression, and propose a new hybrid pre-cast member composed of steel tube, cement grout andwood (WGFST) to satisfy the requests from developing area.

Tidal energy

1
Optimization of tidal farms layout
Tidal energy has two main advantages over other traditional renewable sources: its predictability andits periodicity. However, the Levelized Cost of Energy (LCOE) of this technology is still too highcompared with solar PV or wind energy. To reduce this LCOE, we aim to optimize the spatial distributionof tidal turbines in the farm to mitigate wake losses. For this purpose, we use predictions from ocean
models that simulate tidal currents and the impact of turbines on the flow. The accuracy of model
predictions is confirmed by comparing them with data measured in the field.

Optimization of tidal farms layout
Another solution to mitigate wake losses in a tidal farm is optimizing the shape of tidal turbine bladesto accelerate the wake recovery downstream of the turbine. For this, an optimization system that combines
an artificial neural network was combined with a shape search system based on a genetic algorithm toconstruct a system that can efficiently and automatically search for the optimum shape.

4Tidal energy has two main advantages over other traditional renewable sources: its predictability and its
periodicity. Due to these characteristics, tidal energy can facilitate grid management in large grids andreduce the need for energy storage and the usage of backup fossil fuel systems in microgrids of remoteislands. For these reasons, the development of tidal energy technologies and projects in Japan is crucial toachieving carbon net-zero objectives.

The organic electronics and optical devices composed of the functional organic molecules, such as
flexible electronics and optical communication devices utilizing the flexibility of organic molecular
crystals and the nonlinear optical response of the anisotropic molecular structure, respectively, have beendeveloped for the next-generation information and communication technology. I investigate for improving
the device performances by visualizing the spatial distribution of charge carriers and electric polarizations
by means of the optical imaging technique.
(Visualization of charge carriers in Organic FETs)

I developed the optical gate modulation imaging
technique which allows to visualize the charge carrier
distribution in the organic semiconductor layer oforganic field effect transistors. By means of thetechnique, I successfully observed the inhomogeneous
carrier distribution in a polycrystalline organic
semiconductor layer and reveled the anomalous
electro-optic response in a single-crystal semiconductor layer.
(Visualization of electric
polarizations using nonlinear optical responses and development of optical devices)

I observed the spatial distribution of the electric polarizations in organic ferroelectric materials andelector-optic polymers by means of the field modulation imaging technique utilizing the nonlinear opticalresponse induced by the broken inversion symmetry of organic molecules. It was demonstrated that the
micro-meter scale ferroelectric domains and the reversal mechanism in ferroelectric films. The polarization
orientation in the electro-optic polymer waveguide of the optical modulator can be evaluated by thetechnique, which encourages technological innovation with improving the device performance.

We are developing a simple particle measurement method for advanced understanding of the film
deposition process and for the enhancement of its functionality. Laser absorption spectroscopy using an
external cavity diode laser (ECDL) allows us to measure the velocity distribution function of atoms in aplasma and non-invasively measure gas temperature. We also use a retarding field energy analyzer withmagnetic filter (magnetized RFEA) to measure the energy distribution function of positive and negativeions in the process to elucidate and optimize the deposition process.

The stability of fullerene is important for its practical application, yet experimental determination remains
difficult with unacceptably large uncertainties. We have used quantum-chemistry computations to expand
the stability data set by a hundred-fold, with accuracy bettering experiment by an order of magnitude.
These data enabled our development of an accurate model of stability for all fullerenes. With it, we haveidentified fullerenes that would excel in different applications with atomic precision. Our future researchwould also involve endo-fullerenes and hetero-fullerenes with more diversely tunable properties.
4/
Fullerenes are light yet mechanically strong, which makes them an ideal strengthening dopant foradvanced lightweight steel. Our research will identify the optimal fullerene derivatives for theadvancement of modern manufacturing. Fullerene doping also leads to a continuum of (semi)conducting
properties, and we will pinpoint suitable candidates for high-performance/low-energy molecularelectronics devices.

Control of magnetic properties and phase transformation of iron-based magnetic material

As the density of magnetic recording media has increased remarkably, higher performance of magnetic
materials is required. We aim to improve the magnetic properties by changing the crystal structure bycontrolling the phase transformation. We mainly study the effects of the addition of light elements on the
crystal structure and the transformation process in heat treatment.
Fabrication of lightweight, high-strength metal-based composite materials

One of the important issues to meet the demand for energy saving is to reduce the weight of transportationequipment. We are working on the development of metal-based composite materials with high strength bycombining aluminum alloys and magnesium alloys with ceramic fibers and particles such as silicon carbide
and alumina. In order to achieve the ideal strength, it is necessary to reduce casting defects. The purpose ofthis study is optimization of the casting process for fabricating the ideal metal-based composite materials.
Development of multiple functional high-entropy alloys

Recently, high-entropy alloys composed of five-element metal elements with equal atomic ratio are
attracting attention because of their unique mechanical properties. There are many points that are unclear
about the basic physical properties and optimal casting method of high-entropy alloys. I aim to develop
high-entropy alloys that have never been discovered before by clarifying these matters.

We have been developing photofunctional metal complexes, especially Pt complexes and Pt-based
heteropolynuclear complexes containing group 11 metal ions,for luminescent materials. Our research also
focuses on the photophysics of chiral-at-cluster homo- and heteropolynuclear complexes whosechirality is arising from dissymmetry at a cluster core.

Hippocrates of Kos, a Greek physician of the Age of Pericles, described iron as a medicine, indicatingthat relevance of metals in health and disease has long been recognized. Nowadays, not only iron also othermetals such as zinc, copper, etc. are well known to have essential roles in life. Because deficiency andexcess of biometals in our bodies cause neurodegenerative diseases, cancers, and diabetes, it is importantto understand the dynamics of biometals including absorption, sensing, trafficking, storage, and excretionin details. My study focuses on the iron dynamics in human bodyand also
the levels from protein structures to cellularfunctions, by using various advanced techniques asshown in the following keywords.

Metals are essential for sustaining life of all living organisms! I believe that a detailed understanding of themechanisms of metal homeostasis is important for the future, because its breakdown can lead to diseases,
food crises, and environmental problems.
