Aliovalent–Isovalent In/Bi Codoping Strategy for Enhanced Thermoelectric Performance in SrCuSb Zintl Phases

# data[].attributes.descriptions[].description
A co-doping approach is implemented by substituting In and Bi for Sb in SrCuSb, thereby simultaneously tuning carrier transport and enhancing phonon scattering. Polycrystalline samples synthesized by melting, ball milling, and spark plasma sintering shows that In adjusts the hole concentration and preserves high mobility. At the same time, Bi introduces mass/strain-field disorder that softens the lattice and thereby suppresses lattice thermal conductivity. Co-doping also suppresses the formation of secondary phases, improving phase purity and carrier mobility. The optimized composition exhibits a high power-factor of ~1.9 mW/m·K2 and a low lattice thermal conductivity of ~ 0.54 W/m·K at 773 K, yielding a peak zT of ~0.65. The average zT over 300–773 K increases from 0.17 for pristine SrCuSb to 0.32, corresponding to an ~87 % enhancement.

Charge sensing of few-electron ZnO double quantum dots probed by radio-frequency reflectometry

# data[].attributes.descriptions[].description
Zinc oxide (ZnO) has garnered much attention as a promising material for quantum devices due to its unique characteristics. To utilize the potential of ZnO for quantum devices, the development of fundamental technological elements such as high-speed readout and charge sensing capabilities has become essential. In this study, we address these challenges by demonstrating radio-frequency (rf) reflectometry and charge sensing in ZnO quantum dots, thus advancing the potential for qubit applications. A device is fabricated on a high-quality ZnO heterostructure, featuring gate-defined target and sensor quantum dots. The sensor dot, integrated into an rf resonator circuit, enables the detection of single-electron charges in the target dots. Using this setup, we observe the rf-detected charge stability diagram indicating the formation of few-electron double quantum dots and provide the first benchmark of the bandwidth, sensitivity, and readout fidelity of rf reflectometry.

Ceramics With High La

Concentration for Mid‐Infrared Laser Applications

# data[].attributes.descriptions[].description
Exploration of mid-infrared laser materials with broad emission spectra is crucial for the generation of ultrashort pulses, particularly in spectroscopic and material processing applications. The incorporation of La3+ ions into Er:Y2O3, a representative mid-infrared laser material, induces crystal lattice distortion and broadens its emission spectrum. However, the La3+ doping concentration is typically limited to approximately 10 at.% owing to the formation of secondary phases. In this study, transparent (Er0.05Y0.95-xLax)2O3 mixed sesquioxide ceramics with high La3+ concentration of x = 0.2 was fabricated together with x = 0, 0.05, and 0.1 via co-precipitation and low temperature spark plasma sintering (SPS) to investigate the effects of La3+ concentration on mid-infrared emission properties. Both the emission spectral width and luminescence lifetime at approximately 2700 nm increased with increasing La3+ concentration. For x = 0.2, the values were approximately 17 nm and 3.8 ms, respectively, compared to approximately 4 nm and 3.3 ms for x = 0. Although the x = 0.2 sample achieved an in-line transmittance above 80% at 2720 nm, it was still lower than those of samples with lower La3+ content. Microstructural analysis revealed that La3+ addition reduced the average grain size and formed residual pores, likely responsible for increased optical scattering. To eliminate the residual pores, post-hot isostatic pressing (HIP) treatment was conducted at various temperatures, which resulted in improved optical transmittance. We believe that optimizing processing conditions could further enhance optical quality at high La3+ concentrations, making it promising candidates for mid-infrared laser applications.

金属材料データベースのデータモデル開発

# data[].attributes.descriptions[].description
The National Institute for Materials Science (NIMS) has published Structural Materials Data Sheets since 1966. Some data sheets are also available through the online database application “Kinzoku,” which was updated in 2023 with a new unified data model. The Kinzoku data model was constructed by analyzing the implicit structure of long-accumulated data sheets, and by defining entities such as material, piece, properties, and test conditions, as well as their relationships and attributes. Three data formats were implemented based on this model: TSV for daily editing, PostgreSQL for ensuring data integrity and querying, and XML for semantic interoperability. This data model was applied in several scenarios, including an extension of the framework to support liquid hydrogen–related materials data, which is crucial for the development of hydrogen energy infrastructure.

Phenomenological formulation of hybrid transverse magnetothermoelectric conversion in artificially tilted multilayers

# data[].attributes.descriptions[].description
We phenomenologically formulate the appearance of transverse magneto-thermoelectric phenomena, i.e., the anomalous Nernst effect and Seebeck-driven anomalous Hall effect, in artificially tilted multilayers consisting of magnetic and thermoelectric materials, where the off-diagonal Seebeck effect originally exists due to the anisotropic composite structure. Because the contributions of the anomalous Nernst, Seebeck-driven anomalous Hall, and off-diagonal Seebeck effects to transverse thermopower have different artificial structure dependences with each other, the total thermoelectric performance maximizes by optimizing the structure to balance these effects. We confirm the appearance of these thermoelectric effects by performing a finite element analysis of transverse thermoelectric fields in artificially tilted multilayers consisting of ferromagnetic Co2MnGa Heusler alloy and thermoelectric semiconductor Bi2Te3. This work will be a guideline to design the optimum structural parameters for superior transverse thermoelectric performance through the hybridization of spin- and magnetism-related thermoelectric phenomena in artificially tilted multilayers.

An open-source framework for quantitative electrostatic simulations in Kelvin probe force microscopy

# data[].attributes.descriptions[].description
We developed an open-source numerical code for calculating electrostatic interactions between a hyperbolic metallic tip and a conducting surface under Kelvin probe force microscopy (KPFM)-relevant conditions. The code solves the electrostatic potential in the tip-sample vacuum gap under an applied bias by imposing Dirichlet boundary conditions on the tip and sample surfaces, and evaluates electrostatic force observables from the calculated potential. In addition to laterally homogeneous samples, the full three-dimensional implementation treats spatially inhomogeneous surfaces and reproduces contact potential difference profiles. Quantitative comparison with experiments is achieved without arbitrary scale factors or other ad hoc proportionality constants. The method provides a practical framework for experimental-parameter extraction, quantitative KPFM data analysis, and future investigations of contrast formation and other measurement aspects in KPFM.

Protein Separation and Purification Using Inorganic Oxide Materials: From Surface Chemistry to Biochemical Applications

# data[].attributes.descriptions[].description
Inorganic oxide materials are widely used for protein and peptide separation because their surfaces support multiple types of interactions, including metal-centered coordination, electrostatic interactions, and both hydrophilic and hydrophobic interactions. This review summarizes the binding mechanisms between proteins/peptides and representative inorganic oxides – ZrO2, TiO2, SiO2, Fe3O4, Al2O3, ZnO, CeO2, SnO2, Nb2O5, Ta2O5, and Ga2O3. Particular emphasis is placed on the comparative analysis of adsorption mechanisms across these inorganic oxides and on factors such as crystal structure, surface acidity, and surface functionalization that influence adsorption selectivity. The review further discusses the effects of surface chemistry on purification performance and their combined effects on multi-step purification workflows. Recent advances in surface engineering and hybrid material design are highlighted to provide perspectives for the development of selective and mild protein purification processes. This framework offers guidance for the rational selection of inorganic oxide materials, enabling reproducible, selective, and mild purification of diverse proteins and peptides in biopharmaceutical applications.

Pulsed laser deposition of ZnO/MgxZn1-xO superlattices for quantum cascade laser applications

# data[].attributes.descriptions[].description
We developed a precise molecular layer deposition technique using pulsed laser deposition (PLD) to realize a quantum cascade laser (QCL) structure using wide-bandgap semiconductors ZnO and MgxZn1-xO. Compared to GaAs and InP, ZnO has a larger optical bandgap (3.3 eV) and higher longitudinal optical phonon energy (72 meV). This combination suppresses leakage current and promotes fast nonradiative relaxation, making ZnO a promising material for high-temperature QCL devices operating near room temperature. Nanometer-order thickness control is essential for realizing a QCL device structure. However, PLD techniques suffer from fluctuations in the deposition rate caused by viewport contamination. In this study, a quartz crystal microbalance is used to continuously measure the deposition mass during the PLD process. The combination of a cooling and shielding design with an infrared heating system is used to suppress the thermal drift and plasma damage. Consequently, precise molecular layer control is achieved in the periodic structure of the ZnO/MgxZn1-xO superlattice. The prepared ZnO QCL structure is characterized by scanning transmission electron microscopy and X-ray diffraction, which confirms that the designed superstructure is reproduced with high precision. This study establishes a PLD process to realize ZnO-based QCL and paves the way for developing new QCL platforms using wide-bandgap materials.

A data-driven elucidation of the challenges in designing stable quinone derivatives for aqueous organic redox flow batteries: correlations between thermodynamics of chemical degradation and energy capacity metrics

# data[].attributes.descriptions[].description
Aqueous organic redox flow batteries (AORFBs) offer significant potential for grid-scale storage of renewable energy. However, their commercial viability is often limited by the chemical instability of the organic electrolytes. Quantifying and assessing the effects of the various degradation mechanisms from a molecular design perspective is very challenging both experimentally and computationally. Here, we propose the use of simple thermodynamic descriptors for seven degradation mechanisms for a diverse virtual library of ca. 2000 monofunctionalized quinones built from seven core structures. In the process, we developed a cheminformatics-based workflow that can reliably and automatically generate reactants and mechanism-specific degradation products. Using DFT-calculated reaction Gibbs free energies as thermodynamic descriptors and a calibrated model for redox-potential prediction, we systematically analyse seven degradation mechanisms across this library. We find clear relationships between redox potential and degradation thermodynamics for six of the seven mechanisms, with opposite trend directions for oxidized and reduced forms, revealing stability – potential trade-offs that constrain molecular design. The analysis further shows how functional groups modulate degradation thermodynamics, helps rationalize the relative stability of anthraquinone-based outliers. Finally, redox active molecules from recent experimental studies are evaluated within the proposed thermodynamics-based framework, and we comment on the implications of electrochemical reversibility of some critical degradation mechanisms. Overall, this work provides a physically motivated framework for the multi-objective screening of quinone-based AORFB electrolytes and helps clarify the design criteria needed to identify favourable molecular outliers.

Electrochemical Wiring of a Metal Nanofilament to Form a Molecular Junction

# data[].attributes.descriptions[].description
Leveraging the functionalities of molecules in electronic devices seems promising for the development of next-generation technologies. However, wiring from the electrode to a molecular layer is challenging. Here, we introduce a method for connecting microscale metal electrodes to a molecular layer using an atomic switch that controls the formation and rupture of a metal nanofilament using a bias voltage. Specifically, a 1,4-benzeneditiol (BDT) molecular layer is embedded within an atomic switch. A bias sweep applied to the Ag electrode induces a transition between a high-conductive state (2 mG 0, where G 0 = 2e 2/h ) and a low-conductive state (35 µG 0). Both high and low-conductive states exhibit nonvolatile operation. Current–voltage analysis collaborated with the density functional theory simulation reveals that the Ag/BDT/Ag junction with about 20 molecules forms in the high conductive state. These results indicate that our method is effective for wiring between a microscale electrode and a nanoscale molecular layer.

Oxide-dispersion driven phase and microstructural evolution with an analytical framework for critical current density in synergistically yttria-titania doped Nb3Sn

# data[].attributes.descriptions[].description
This study presents a heat treatment–doping effect of individual and synergic nano-oxide Y2O3 and TiO2 dispersoids on Nb3Sn towards the interrelation among phase, microstructure and properties. Synergic doping of Y2O3 and TiO2 to Nb3Sn resulted in Tc of 18 K after annealing at 400 °C for 9 h. A lower Tc of 16 K was observed for as-sintered pristine Nb3Sn. Pristine samples were susceptible to heat treatment, indicated by the wide transition width of 2 K in Tc. A high overall Jc of 5.17 × 105 A/cm2 (10 K, 2 T) was observed for Y2O3 and TiO2 co-doped Nb3Sn sample annealed at 400 °C for 9 h compared to the overall Jc of 2.3 × 105 A/cm2 for as-sintered. Solutionized and quenched samples showed poor overall Jc performance, with the lowest Jc of 9.1 × 104 A/cm2 for the pristine. A higher NbO phase fraction led to a degraded overall Jc performance in TiO2 doped sample. A superior overall  performance for co-doped sample was due to the synergic presence of Y2O3 and TiO2 at grain boundaries of Nb3Sn which acted as blanket to restrict the NbO formation. An analytical model to predict the microstructurally governed overall Jc performance at different applied fields was developed.

Evaluation method for the interfacial strength of thermally grown Al2O3 scale and Ni-Al alloy

# data[].attributes.descriptions[].description
Nanoindentation techniques are useful for evaluating the critical load for crack initiation on interface between Ni-Al alloy and thin surface Al2O3 scale formed at high temperature, since interfacial cracking can be clearly detected as a pop-in event. However, actual interfacial stress applied during loading and when cracked is unclear, due to the multiaxial stress field. Here we analyzed interfacial stress distribution during the nanoindentation using finite element analysis. Elastoplastic simulations of nanoindentation were performed with local stress-strain curves for oxide scale and the Al depletion zone. Local stress-strain curves were inversely analyzed from experimental load-penetration depth curves, obtained using separate nanoindentation tests. Interfacial stress was obtained as a function of indentation load, clarifying that shear stress acting on interface contributed significantly to crack initiation. The two-parameter Weibull plots of interfacial strength σ_(Int,max)^c were converted from pop-in load Pc obtained in experimental nanoindentation tests for samples with different amounts of impurity S segregation. Largest differences appear where fracture probability F is low; for F=4%, difference of approximately 780 MPa between the sample with higher S segregation level (high Sinterface alloy, σ_(Int,max)^c=1.73 GPa) and lower S segregation level (low Sinterface alloy, σ_(Int,max)^c=2.51 GPa) were obtained.

# data[].attributes.descriptions[].description
We propose (−112) and crystallographically equivalent (1−1−2), (−1−12), and (11−2) planes as fundamental crystal orientations for β-Ga2O3 studies. In homoepitaxy, the epilayer exhibited single crystallinity with tilt and twist dispersions comparable to those of the substrate and a step-and-terrace surface morphology with a root-mean-square roughness of 0.10–0.12 nm. Although slit-like pits whose sidewalls were vertically aligned (100) facets appeared on the surface, these pits were attributed to SiO2 nanomasks at the interface and are expected to be eliminated by improving pre-growth surface treatments or the initial growth process. Furthermore, the concentration of Cl impurities in the epilayer was as low as 1×1015 cm−3, which was significantly lower than 2×1016 cm−3 observed in the simultaneously grown (001)-oriented homoepitaxial layer. For HCl gas etching, selective-area etching was performed using a SiO2 mask with patterned windows. The etched structures clearly reflected the intrinsic crystal anisotropy. Side etching was minimized when the windows were aligned along the [02−1] direction due to the formation of exceptionally flat and vertical (100) facets, which possess the lowest surface energy density. Additionally, the vertical etch rate for the (−112) plane was approximately 50 times higher than the side etch rate for the (100) plane, enabling precise fabrication of high-aspect-ratio fins and trenches. These results—particularly the excellent surface smoothness achieved in homoepitaxy and the high-aspect-ratio patterning enabled by HCl-gas etching—demonstrate that the {−112} orientations are promising candidates for β-Ga2O3 studies.

Understanding diffraction from disordered materials: toward the analysis beyond the intermediate-range order

# data[].attributes.descriptions[].description
Understanding structure of non-crystalline materials is still challenging topic in physics due to the inherent nature of disorder in non-crystalline materials. Diffraction is a powerful measure to reveal atomic structure of crystalline materials because of well-defined theory of crystallography developed on the basis of the understanding of Bragg peaks observed in diffraction data. However, diffraction patterns of non-crystalline materials exhibit so called halo pattern owing to inherent disorder in atomic arrangement. The use of pair distribution function obtained from a Fourier transform of normalized diffraction data provides short-range structure in terms of atomic distance and coordination number. The atomic structure beyond the short-range structure, so called intermediate (medium)-range order has been widely studied by X-ray and neutron diffraction measurements from the late 1980s. In particular, the advent of advanced quantum beam facilities in the late last century provides high-flux synchrotron X-rays and neutrons to reveal the intermediate-range structure of non-crystalline materials by understanding of diffraction peaks aided by the advanced computer simulation techniques. In this article, we review recent advances in our studies [8–10] and address a future direction to understand the atomic structure of non-crystalline materials beyond the intermediate-range order.

Automated and high-throughput evaluation system of process-structure-property dataset for Ni-base superalloy

# data[].attributes.descriptions[].description
Superalloys used in aircraft engines applications are composed of numerous elements and complex hieratical microstructures, requiring a large amount of high-quality process-structure-property dataset for optimizing their structure and processing. Recent advances of computational simulation will be helpful for optimization of alloy structure, designing new superalloys to meet a given set of material properties without experimental trial and error is still unfeasible. Here, we proposed a novel automated high-throughput method capable of　gathering 2400 data points relating processing conditions, microstructure geometry and yield strength in 13 days. An estimated 200 times faster than conventional methods using tensile testing specimens, a complete Process-Structure-Property (P-S-P) dataset is created from a single sample. The method to rapidly assemble comprehensive and consistent P-S-P datasets can facilitate efficient alloy design.

Effect of carbon content on boundary deformation behaviour in martensitic steels

# data[].attributes.descriptions[].description
This study aims to clarify the different boundary deformation mechanisms between medium-carbon lath martensite and high-carbon martensitic steels. In medium-carbon martensite, boundary deformation can trigger the activation of minor slips in surrounding blocks, leading to local strain partitioning. Compared with normal intra-block slips along in-lath-plane slip systems, these boundary-induced minor slips occur on planes aligned with the deformed boundaries. On the other hand, boundary deformation in high-carbon martensite is strictly confined along the boundaries, forming intense single-peak strain concentration bands. When the high-carbon martensite is tempered at 500°C, the boundary-induced minor deformation bands are observed again. This indicates that the activation of boundary-induced minor deformation primarily depends on the local critical resolve shear stress (CRSS) around the boundaries, instead of the carbon-induce microstructure variation. When primary boundary deformation occurs, high CRSS impedes the activation of surrounding minor deformation, leading to strain concentration along the boundaries. With low CRSS, minor deformation can be activated near the primary boundaries, leading to strain partitioning effect and improved overall ductility.

In this study, the effect of microenvironmental viscosity on the cellular uptake of magnetic nanoparticles and the efficiency of magnetic hyperthermia were investigated by culturing colorectal cancer cells in media of different viscosities. Results showed that the cellular uptake of magnetic nanoparticles significantly decreased with increasing microenvironmental viscosity, which further decreased the intracellular heating effect of magnetic nanoparticles. Furthermore, the proportion of apoptotic cells induced by magnetic hyperthermia was significantly reduced in high viscosity microenvironments, and the most viscous microenvironment exhibited the lowest apoptosis rate. This study revealed the important role of microenvironmental viscosity in regulating the cellular uptake of magnetic nanoparticles and the efficiency of magnetic hyperthermia.

Dilute magnetism and edge-state engineering in monolayer SnO

# data[].attributes.descriptions[].description
Tin monoxide (SnO) is a p-type oxide semiconductor whose electronic properties can be widely modified through atomic-scale engineering. Using first-principles density functional theory, we investigate the effects of transition-metal doping and edge engineering in monolayer SnO. Cobalt doping induces pronounced spin polarization near the Fermi level through Co 3d–O 2p hybridization, leading to a nearly spin-selective electronic structure. We further show that SnO nanoribbons host intrinsic edge-localized states. For chiral nanoribbons oriented along a low-symmetry direction of the square lattice, oxygen-rich edges are thermodynamically most stable and remain semiconducting, whereas tin-containing edges support metallic one-dimensional conduction channels. These results establish design principles for controlling electronic states in low-dimensional p-type oxide nanostructures.

# data[].attributes.descriptions[].description
Improving the spin mixing conductance at the ferromagnet/heavy metal (FM/HM) interface with a low Gilbert damping constant in the FM layer is a key requirement for developing efficient spintronic devices. To evaluate the potential of Co2FeGa0.5Ge0.5 as the FM layers in such structures, epitaxial Co2FeGa0.5Ge0.5 single-layer and Co2FeGa0.5Ge0.5/Pt bilayer films were deposited on MgO substrate using magnetron sputtering, and their Gilbert damping constants were evaluated from ferromagnetic resonance spectra. While the single-layer samples exhibit a low damping constant of ~ 1.07×10-3, an enhancement in the damping constant was observed in the bilayer samples due to spin pumping across the Co2FeGa0.5Ge0.5/Pt interface, from which relatively large spin mixing conductance (g_(eff_Pt)^(↑↓)) of (2.78±0.09)×1019 m-2 was evaluated. Further, to investigate the effect of interface property on g_(eff_Pt)^(↑↓), ultrathin (~ 0.2 nm) Cu, Ni, Ru, Ta, or Cr insertion layers were introduced between the Co2FeGa0.5Ge0.5 and Pt. The observed change in g_(eff_Pt)^(↑↓) depends on the insertion material, indicating that their physical properties, such as magnetic, non-magnetic, antiferromagnetic, light or heavy metal, reflect on g_(eff_Pt)^(↑↓)
