The Detail Matters: Unveiling Overlooked Parameters in the Mechanochemical Synthesis of Solid Electrolytes
"Simply mixing the reagents by hand for a short time in a mortar and pestle before mechanochemical synthesis dramatically improves the performance of the solid electrolyte. Hand mixing changes the crystallization behavior, improving the ionic conductivity of the solid electrolyte by up to an order of magnitude. This discovery will accelerate the search for efficient and logical new electrolyte materials, and ultimately the development of all-solid-state batteries."

Creation of a Novel Evaluation Method for Assessing the Efficacy of Water Treatment Processes on Hard-to-Culture Viruses Without Relying on Conventional Cell Culture Approaches
This study aims to elucidate the removability of "non-culturable" viruses, such as norovirus, in water treatment processes—whose behavior in such treatments remains completely unknown. In this study, virus-like particles (VLPs) composed of viral capsid proteins will be produced using genetic engineering techniques. By incorporating foreign genes into these VLPs using non-viral vector construction methods and applying them to water treatment experiments, we seek to establish a novel evaluation method for viral removability that does not rely on cultivation.

CO₂ electrochemical reduction by Zn-based layered double hydroxides: The role of structural trivalent metal ions
Carbon dioxide electrochemical reduction (CO2ER) has attracted attention because of its potential to convert CO₂ into valuable chemical materials using renewable energy. In this study, we evaluated the electrocatalytic activity of Zn-Cr, Zn-Ga, and Zn-Al layered double hydroxides (LDHs) for CO2ER. We found that these LDHs exhibited CO2ER activity for CO evolution, and the type of M³⁺ in the Zn-based LDHs affected their CO2ER performance. This research was a collaboration with the University of Antwerp, Belgium, and the Institute of Ceramics and Glass, CSIC, Spain

Understanding the active catalyst surface structure on Ru-doped Ni/CeO₂ catalysts for CO₂ methanation
Converting CO₂ into valuable compounds using renewable hydrogen is a promising strategy for achieving a decarbonized society. We previously demonstrated that Ni-based catalysts efficiently convert CO₂ into methane, the main component of city gas. In this study, we combined expertise in chemical engineering, computational chemistry, and physics to uncover the surface structure of the developed catalyst.

Lack of Oscillatory Motion of Superfluid ⁴He During its Dripping from a Needle
Although pendant droplets commonly exist in our daily lives, their dynamics are not fully understood. To obtain further understanding of its physics, we observed superfluid helium dripping from a thin needle by a high-speed camera. Superfluidity is an inviscid liquid state only happening in helium at low temperatures. The present study where we used a thin needle to eliminate the droplet’s remnant volume clearly demonstrated that the dissipation-less large oscillation observed in the previous experiments was crucial for the discretization of the dripping period which is novel phenomenon reflecting the anomalous fluid properties of superfluid helium.

Study on long-term subsidence of soft clay due to Niigata-ken Chuetsu-oki earthquake of 2007
In the 2007 Niigata-ken Chuetsu-oki Earthquake, ground liquefaction was severe in sandy areas, but long-term settlement occurred in soft clay in Kashiwazaki’s Shinbashi district. Even without visible damage, the ground sank 71 mm over 14 years. We studied this by boring and testing soil samples, finding the clay to be soft and highly compressible. Using a specialized computer model (TS-CM), we successfully simulated the ground’s behavior, showing that this type of clay is prone to long-term sinking after earthquakes due to water pressure buildup and delayed consolidation. These findings help predict future ground behavior in similar soils.

Seismic performance of a bridge pier integrated by multiple steel pipes with directly-connected piles using soil-water coupled with three-dimensional elasto-plastic finite element analysis
A new type of bridge support using connected steel pipes was tested to see if it performs as well as traditional designs during earthquakes. Small-scale shaking tests showed that it works just as well or even better. However, since only one type of shaking was tested, we are now using computer simulations to see how it reacts to different kinds of earthquake motions. This will help us better understand how safe and reliable this new bridge design is for the future.

Photoinduced Metal–Insulator Phase Separation Depending on the Conformational Order of Molecules in β-(BEDT-TTF)₂I₃
In this study, the role of the conformational order of organic molecules in photo-induced phase separation (PIPS), which forms the basis for ultrafast switching devices, is investigated. The results show that PIPS occurs below 150 K in the partially ordered phase and below 75 K in the homogeneously ordered phase. This result implies that conformational order plays a crucial role in determining the temperature at which PIPS occurs, providing significant insight for room-temperature operation, which is essential for the practical application of devices.

Transport of radioactive elements in concrete due to utilization of recycled aggregate contaminated with nuclides
In the future, a huge amount of concrete waste will be generated in preparation for the demolition of nuclear power plants. From the perspective of rational processing and disposal, it is possible to reuse this waste, particularly waste with low levels of radioactivity, as recycled aggregate. Clarifying how radioactive materials migrate inside concrete is extremely important in building a safe and secure society.

Nucleation probability of methane + propane mixed-gas hydrate depending on gas composition
Natural gas hydrate contains large amounts of natural gas and is attracting attention as one of the future domestic resources, or as its storage and transportation medium. For its industrial use, it is one of the problems that the nucleation process is difficult to control. This study has revealed that the nucleation probability of methane + propane mixed-gas hydrate, as a mimic of natural-gas hydrate, depends on the composition. This result will help develop technology for industrial use of gas hydrates.

Effect of Wet−dry Cycles and Water-to-cement Ratios on Cement Paste Carbonation
Cement production consumes a significant amount of energy and releases CO₂ emissions, while concrete waste can potentially reabsorb CO₂. This study examined the effect of relative humidity (especially wet-dry cycles) on the carbonation of hardened cement pastes. Wet–dry cycles increased porosity and caused the decomposition of calcium silicate hydrate (C-S-H) through shrinkage and deformation during drying. As a result, the highest CO₂ absorption in the wet-dry cycle sample was twice that of the constant RH. Additionally, the amount of CO₂ captured during the 28-day wet-dry cycle accounted for about 17% of the annual CO₂ emissions from cement production.

Unveiling the origin of diffusion suppression of hydrogen isotopes at the α-Al₂O₃(0001)/α-Cr₂O₃(0001) interfaces
Hydrogen in metallic materials causes degradation known as hydrogen embrittlement, which renders the materials brittle. Therefore, to promote the use of hydrogen energy in applications such as fuel cells and nuclear fusion reactors, strategies to prevent hydrogen permeation into structural materials are essential. In this study, we elucidated the mechanism by which coating multiple layers of different ceramic films on metal surfaces, which serve as hydrogen permeation barriers, can more effectively suppress hydrogen permeation than single-layer ceramic films. This research can contribute to extending the service life of metallic materials in a hydrogen environment.

Recovery of phosphate from carbonized sewage sludge by chlorination
The present research group has recently found a method to recover phosphorus, which is called “biological and technical nutrient”, from sewage sludge as phosphorus chloride forms. Specifically, we have developed a simple sewage sludge recycling technology that first carbonizes sewage sludge to improve handling, then chlorinates the resulting carbonized material at 500℃, and finally separates phosphorus chloride species and impurities by a cooled deposition method. This method can be applied to sewage sludge incineration ash, livestock manure, steelmaking slag, etc.

Pore properties and CO₂ adsorption performance of activated carbon prepared from various carbonaceous materials
The production of activated carbon using biomass and coal as carbon sources, melamine as a nitrogen source, and K₂CO₃ as a chemical activator revealed that the lower carbon content and lower ash content of the carbon source resulted in better pore development, and that the surface area and micropore volume of activated carbon affected the CO₂ adsorption capacity. It was also shown that the optimal micropore size for CO₂ adsorption is 0.5 to 1.2 nm. These results are expected to lead to the establishment of production guidelines for activated carbon with high CO₂ adsorption capacity.

Imaging valley-vortex edge modes in a phononic crystal at ultrahigh frequencies
We perform optical measurements and numerical simulations of guided phonon propagation in novel topological phononic crystal structures at ultrahigh frequencies. The structures support valley-polarized states that exhibit an energy vortex nature and propagate with high efficiency at domain boundaries because backscattering is suppressed due to conservation of time reversal symmetry. We extract frequency- and time-resolved spatial mode patterns and -space images, together with dispersion relations. We investigate the conditions required for robust propagation along interfaces and thereby observe very high efficiency waveguiding.

Novel continuous-time crystallinity observed in a superfluid dripping system
While the dripping period of a classical viscous fluid is widely distributed due to the influence of chaos, the dripping period of a superfluid 4He liquid is discretized to a constant value specified by integers even if the inflow rate changes. We clarify that this robust discretization is the realization of a continuous-time crystal from the viewpoints of inflow rate phase diagram, temperature phase diagram, wall shape and dimensionality, and time-domain phonon excitation.

Mechanisms underlying the dynamic strength of cancellous bone based on the impact strength of individual trabeculae and microarchitecture
Osteoporotic fractures occur in cancellous bone due to even minor impacts. In addition to bone mass, the impact strength of individual trabeculae and the microarchitecture are hypothesized to determine the dynamic strength of cancellous bone. This study aims to experimentally clarify these mechanisms and apply the findings to further improve the control of dynamic fracture risk.

Study of Quantum Plasticity and Supersolidity of solid 4He by Observing Motion of Sinking Object
Solid helium is often referred to as quantum solid and known to deform easily and rapidly even under tiny force, strongly subjected to quantum effect. A number of research have been conducted to study its elasticity, or reversible deformation, but its plasticity, or irreversible deformation, is scarcely understood. In the proposed experiment, we are going to precisely measure the motion of objects sinking in solid helium to elucidate the quantum effects on the plasticity of solid helium. Especially, the local superflow expected to exist in cores of dislocations and grain boundaries are to be examined, in the context of supersolidity.

Development of dimension reduction scheme for data assimilation using criticality experiments
The nuclear cross section uncertainty given as a covariance matrix will be used to evaluate the realistic range of important parameters in the safety analysis of nuclear reactors. In recent discussions, the application of data assimilation is considered important to incorporate criticality experiment findings. However, there is a practical issue to treat the covariance matrix after applying data assimilation because the covariance matrix becomes much denser one by causing complex correlated components and the computational cost becomes increased. This research project develops a dimension reduction scheme to solve this practical issue.

Material Behavior and Mechanical Performance Based on Hierarchical Structure Formation of 3D-Printed Concrete
This study investigates the hierarchical structure of 3D-printed concrete (3DP concrete) by analyzing two key aspects: the microscopic heterogeneity caused by material segregation within the filament during deposition, and the macroscopic non-uniformity resulting from interfacial voids formed along the printing path. By clarifying these higher-order structures, we demonstrate that 3DP concrete possesses multiscale material properties and mechanical behavior, making it a hierarchical material. Furthermore, we establish a systematic academic framework for understanding how heterogeneity (material geometry) and non-uniformity (structural geometry) are embedded as geometric parameters in 3D spatial information, providing insights into the mechanical performance and failure modes of 3DP concrete.

A study on the application of accelerated carbonation cement paste powder by wet-dry cycle technique to supplementary cementitious material
Carbonated recycled concrete paste can serve as a supplementary cementitious material (SCM) with pozzolanic properties from alumina-silica gel. Additionally, since it contains fine particles of calcium carbonate, it is expected to enhance concrete performance through its filling effect when used as SCM. Previous studies have shown that the wet-dry cycle method promotes CO₂ absorption and increases the porosity of concrete paste. Based on this, the study aims to efficiently absorb CO₂ using waste concrete paste through the wet-dry cycle method and seeks to recycle resources and enhance concrete performance by reusing the carbonation products as SCM.
