  • Ab Initio molecular dynamics study of threshold displacement energy in Zirconium Nitride Reviewed International journal

    Zirconium nitride (ZrN) is a promising matrix candidate for advanced nuclear fuels and transmutation of minor actinides. This study investigates the displacement process induced by low-energy recoils in ZrN using ab initio molecular dynamics (AIMD) simulations to evaluate the threshold displacement energy (Ed). Observations of the collision processes of primary knock-on atoms (PKAs) for both Zr and N atoms were performed for seven different directions: [100], [110], [111], [210], [211], [221], and [321], which cover most regions of the stereographic triangle. The values of Ed ranged from 15 eV to 50 eV, and the collision processes were dependent on the crystallographic orientations. The weighted average values of Ed evaluated from the PKA directions investigated in this study were 33 eV and 29 eV for the Zr and N atoms, respectively. Anti-site defects were not formed for either Zr or N PKAs. Sequential replacement collisions along the [110] atomic row played an important role in the collision process, providing a lower value of Ed in the crystallographic directions. Furthermore, configurations of interstitials were different between the Zr and N atoms, which also influenced Ed values.

  • Transition of Cationic Local Structures in Mg1- xNixAl2O4 Reviewed International journal

    In this study, cationic local structures in the series of MgAl2O4–NiAl2O4 solid solutions (Mg1-xNixAl2O4) were examined using Mg, Al, and Ni K-edge X-ray absorption near-edge structure (XANES). Theoretical calculations of XANES using the all-electron full-potential augmented plane-wave in addition to the local-orbital method were performed to investigate the transition of the cationic local structures depending on their compositions. For the calculations, the atomic coordination was studied using crystal structures of normal and ordered inverse spinels. The experimental spectra of the end members MgAl2O4 and NiAl2O4 were successfully reproduced from the theoretical spectra. Furthermore, the inversion degrees of the end members, analyzed using the calculated spectra, were consistent with previous experimental reports. The Ni2+ ions show three kinds of local structures, and their volume fractions change depending on the composition of Mg1-xNixAl2O4, whereas the Mg2+ ions show two kinds of local structures. The Al3+ ions change the local structure between tetrahedral and octahedral sites to balance the behaviors of Mg2+ and Ni2+ in the compositions. Although the analysis using XANES provides rich information, a theoretical approach is desirable for reliable and quantitative analysis of multication oxides and their disordering.

  • Cathodoluminescence of cerium dioxide: Combined effects of the electron beam energy and sample temperature Reviewed International journal

    Language:English   Publishing type:Research paper (scientific journal)  

    In-situ cathodoluminescence (CL) spectroscopy is used to study point-defect formation in cerium dioxide (CeO2) by high-energy electrons (400 keV-1,250 keV) at ∼100 K, 200 K, and 300 K in a high-voltage electron microscope (HVEM). Complementary CL spectra are also obtained for 20-keV electron excitation at ∼300 K in a scanning electron microscope (SEM). Experiments were carried out on a single crystal and polycrystalline sintered sample. The more prominent and broad emission band centered at a photon energy of ∼4.2 eV is ascribed to F+ centers (oxygen vacancies) produced by the high-energy electron irradiation. Two other weaker CL bands centered at ∼2.3–2.4 eV and 2.8–2.9 eV at 300 K are related to trivalent cerium ions, corresponding to 5d → 4f radiative transitions, regardless of electron energy. Similar spectra are recorded at 100 K and 200 K, yet with shifts and broadening of the latter emission bands. A maximum of all CL bands is found at ∼600 keV electron energy for the polycrystalline sample regardless of temperature, and for the single crystal at 300 K. In contrast, a continuous increase versus electron energy is observed for the 4.2-eV band of the single crystal at 100 K and 200 K above a threshold corresponding to the oxygen displacement energy. The dependence of CL intensities on the primary electron energy is analyzed on the basis of the interplay of the luminescence cross section and oxygen displacement cross section. The electron energy dependence of ionization cross sections is addressed by relying on secondary electron spectra computed with the PHITS code which is benchmarked against other computer codes such as PENELOPE, as implemented in Geant4. The F+ center band intensity is strongly reduced in the polycrystalline sample with respect to the single crystal in the same irradiation conditions regardless of temperature due to grain boundaries

    Damaged structures in the MgAl2O4 spinel induced by swift heavy ions were investigated using the X-ray absorption near edge structure (XANES) and small angle X-ray scattering (SAXS). Increasing the fluence of 100 MeV Xe ions leads to increased SAXS intensity and XANES spectral changes on both Mg and Al K-edges. The damaged regions of ion tracks were observed by SAXS to be cylindrical in shapewith a diameter of 5 nm. The theoretical XANES spectra indicated that the changes in the experimental spectra were due to the cationic disordering between tetrahedral and octahedral sites. This disordering caused an increase in the inversion degree of the cations. Furthermore, the quantitative analysis of the XANES spectra revealed the preferential occupation of cations at the octahedral sites at high fluence.

  • Cathodoluminescence of CeO<sub>2</sub> doped with Gd<sub>2</sub>O<sub>3</sub> in a high voltage electron microscope

    Ceria (CeO2) doped with Gd2O3 (Ce1−xGdxO2−x/2) is considered a surrogate of a burnable poison-doped nuclear fuel. Oxygen vacancies (VO) are induced in Ce1−xGdxO2−x/2 by the substitution of Gd3+ ions into the Ce4+ sites, and the oxygen deficiency is mainly controlled by the Gd2O3 concentration. Oxygen vacancies can also be generated by elastic collisions with high-energy electrons for recoil energies of oxygen atoms above the threshold displacement energy (Ed,O). Oxygen vacancy formation is a key factor to determine the radiation tolerance since it enhances the recombination of point defects. The behavior of point defects in ceramics is known to depend on their charge states, although there is only limited research on this topic. In this study, in situ cathodoluminescence (CL) spectroscopy is applied to studying the charge states of defects induced in the oxygen-deficient cerium dioxides, Ce1−xGdxO2−x/2, by using a high-voltage electron microscope for electron energies from 400 to 1250 keV. The CL emission bands of Ce3+ − VO, Ce3+, and F+ centers are obtained for Ce1−xGdxO2−x/2 as well as pure ceria. An energy shift and quenching of CL emission in Ce1−xGdxO2−x/2 are observed. Those effects are discussed as a consequence of the generation of extrinsic oxygen vacancies induced by Gd2O3 doping (VO,ext) and the influence of the respective electronic configurations of the Ce3+ ions and VO,ext. A schematic picture of energy levels of defects in the bandgap of Ce1−xGdxO2−x/2 is suggested.

    ZrN is a promising material for inert matrix fuel and transmutation targets in advanced nuclear applications. The nucleation-and-growth process of radiation-induced defects in zirconium nitride (ZrN) has been investigated in situ under electron irradiation by using a high voltage transmission electron microscope (HVEM) under the production of isolated Frenkel defects for both Zr and N atoms. Electron irradiation with 1250 keV at a constant electron flux of 4.4 × 1022m-2s−1 formed dislocation loops in a temperature range from 873 to 1273 K. The g·b analysis on the dislocation loops revealed that the Burgers vector of loops was parallel to 〈1 1 0〉 direction, indicating the formation of stoichiometric perfect-type dislocation loops. The areal density of loops increased with time to saturate above around 3000 s, and the saturation density decreased with increasing irradiation temperature. Analysis of the accumulation and saturation of dislocation loops using a rate equation showed that the formation of loops is controlled by diffusion and recombination of point defects with N vacancy formed by the non-stoichiometric composition (ZrN1-x). Further, the migration energy of interstitials for the rate-controlling species was evaluated to be 0.48 ± 0.07 eV.

    Alloys based on the Sn-Bi system are widely considered as the most promising candidates for low temperature solders (LTS) in the electronics industry due to their low liquidus temperature, non-toxicity and relatively low cost. However, implementation of LTS is complicated as they exhibit different characteristics from conventional Pb-free solders. While the solid solubility of alloying additions in Sn is typically <1 wt% in the current generation of Pb-free solders, the solubility of Bi in Sn ranges from less than 3 wt% at room temperature to 21 wt% at the eutectic temperature of 139 °C. In consequence, the microstructure and properties of Sn-Bi solders change significantly under varying temperature during normal service, affecting reliability. Since these changes are time and temperature dependent, interpreting results obtained using ex-situ methods requires assumptions about the stability of the alloy during transitions from the test environment to the observation environment, leading to an incomplete understanding of these changes. To address this, in-situ synchrotron powder X-ray diffraction (PXRD) and in-situ scanning electron microscopy (SEM) techniques were developed to investigate the time-temperature dependent lattice and microstructure of hypo-eutectic Sn-37wt%Bi and near-eutectic Sn-57wt%Bi solder alloys. This made possible for the first time the observation of changes during temperature fluctuations. The study revealed that lattice and microstructure are highly sensitive to factors like temperature ramp rate and isothermal holding time, not previously considered. The results will impact the design of electronic circuitry and process parameters during electronics assembly to enhance reliability and performance.

  • Near-infrared study of radiation damage in cerium dioxide

    Radiation damage is studied in electron-irradiated cerium dioxide (CeO2) single crystals. Near Infra-red (NIR) spectra are recorded at room temperature between 2800 and 11,000 cm−1 (i.e. ∼0.9–3.57 µm in wavelength and ∼0.35–1.36 eV in photon energy). Measurements were carried out in the transmission mode for the single crystals and diffuse reflectivity mode for sintered CeO2 and (Ce, Gd)O2-x reference un-irradiated samples. The ceria single crystals were irradiated with 1.4-MeV and 2.5-MeV electrons for high fluences up to 3 × 1016 cm−2. Five broad absorption bands centered at 3600, 4100, 4600, 6000, and 7100 cm−1 (i. e. ∼0.44, 0.51, 0.57, 0.74, and 0.88 eV) are deduced from fits for the 2.5-MeV electron irradiation, whereas no absorption band is recorded for the 1.4-MeV electron energy. Those bands are consistent with the broad 0.9-eV band (7260 cm−1, 1.37 µm) in the UV–visible range associated with the change in color from light blue to deep green for the 2.5-MeV energy. Optical absorption arises from point-defect formation by elastic collisions for electron irradiation above the threshold energy near 1.4 MeV corresponding to the onset of cerium atom displacement. No defect bleaching occurs after isothermal annealing at 700 °C. No such bands are recorded for the virgin (Ce, Gd)O2-x samples for 5, 10, and 15 mol% Gd2O3 with an increasing amount of oxygen vacancies. The origin of absorption bands in the NIR range is discussed in relation to the available experimental data and ab-initio calculations of point defects in CeO2 and other dioxides with the cubic fluorite-like structure. Absorption bands are tentatively assigned to electronic transitions involving cerium vacancy levels in the band gap.

    Bulk Mg-based hydrogen storage materials have the potential to provide a low-cost solution to diversify energy storage and transportation. Compared to nano powders which require handling and processing under hydrogen or an inert gas atmosphere, bulk Mg-based alloys are safer and are more oxidation resistant. Conventional methods and existing infrastructures can be used to process and handle these materials. However, bulk Mg alloys have smaller specific surface areas, resulting in slower hydrogen sorption kinetics, higher equilibrium temperatures, and enthalpies of hydride formation. This work reviews the effects of the additions of a list of alloying elements and the use of innovative processing methods, e.g., rapid solidification and severe plastic deformation processes, to overcome these drawbacks. The challenges, advantages, and weaknesses of each method and future perspectives for the development of Mg-based hydrogen storage materials are discussed.

    The microstructure of virgin and heavy ion-irradiated Ce1-xGdxO2-x/2 with a wide range of Gd dopant concentrations (0 ≤ xGd ≤ 0.5) was evaluated by x-ray diffraction (XRD), micro-Raman spectroscopy, and transmission electron microscopy (TEM) for selected area electron diffraction (SAED) analysis and plane-view bright-field (BF) imaging of ion tracks. The Ce1-xGdxO2-x/2 samples were irradiated with 200-MeV Xe14+ ions up to fluences from 3 × 1011 to 1 × 1013 cm-2 at ambient temperature. XRD patterns of the virgin Ce1-xGdxO2-x/2 samples showed saturation of lattice parameter and relaxation of microstrain in Ce1-xGdxO2-x/2 which are attributed to the increasing Gd concentration. Moreover, micro-Raman spectroscopy and SAED patterns revealed the bixbyite (C-type) structure formation and oxygen vacancy ordering for xGd > 0.2 that is induced by dispersed C-type domains in the fluorite-structured (F-type) matrix. In the irradiated samples, asymmetric XRD peaks induced by lattice distortion were observed together with ion tracks in BF-TEM images. The radiation damage was recovered with the increase of Gd concentration. There is a rapid reduction of radiation damage cross section for xGd > 0.2 with a reduction of the C-type structure reflections in XRD and SAED patterns.

    Raman scattering is applied to probe the radiation damage in swift heavy ion-irradiated ceramics, namely zirconium nitride (ZrN), ceria (CeO2), and yttria-stabilized zirconia (ZrO2: Y, or YSZ) for about the same high electronic stopping power of heavy ions. Raman spectra show that these ceramics are radiation-resistant materials that are not amorphized by such irradiations even for large ion track overlap at high fluences. However, for ZrN, the increase of the TA/LA and TO/LO band intensities versus fluence is evidenced after 100-MeV Xe ion irradiation up to a saturation for the fluence of 3 × 1012 cm−2. The band growths are ascribed to the increase of the concentration of Zr and N vacancies induced by electronic excitations inside tracks. However, the diffuse reflectance spectra do not exhibit any clear modifications of the electronic structure. For ceria, the decrease and broadening of the main F2g peak of the fluorite-like structure and the growth of a broad defect band assigned to oxygen vacancy formation is observed versus fluence up to 1014 cm−2 for 200-MeV Xe ion irradiation. For YSZ, Raman spectra mainly give evidence of the intrinsic lattice disorder due to the native oxygen vacancies even up to high fluences of about 3 × 1013 cm−2 for 200-MeV I and 200-MeV Au ion irradiation. Results are discussed on the basis of the interplay between the native structural disorder and the radiation-induced disorder by electronic excitations in these three materials.

    The radiation damage induced in cerium dioxide CeO2 and cerium-gadolinium mixed oxides (Ce, Gd)O2-x was studied by micro-Raman spectroscopy and diffuse UV-visible reflectance spectroscopy. Sintered samples of undoped CeO2 and (Ce, Gd)O2-x for 1 mol% and 5 mol% of Gd2O3 were irradiated at room temperature with 2.5-MeV Ar2+ and 12-MeV Ar4+ ions up to high fluences (i.e. 5 × 1014 cm−2 and 2.1 × 1014 cm−2 respectively). The Raman spectra show that no amorphization of those oxides occurs whatsoever, regardless of the Gd content. No clear change of the damage cross section with the Gd3+ content is deduced from the decay of F2g peak intensity versus fluence. Moreover, the reflectivity spectra show a clear decrease of the band-gap energy and increase of the Urbach energy arising from point defect accumulation. Similar effects are found for 1 mol% and 5 mol% Gd2O3, whereas a larger effect on band tailing is seen for undoped ceria. The respective roles of nuclear collisions and electronic excitations are discussed for both ion energies knowing that the two kinds of measurements do not probe the same sample depth. The substitution of Gd3+ ions for Ce4+ ions is likely reducing the damage and the formation of band tails related to the formation of Ce3+ ions by electronic excitation processes.

    The sink strengths of precipitate/matrix interfaces in Cu alloys, were investigated by performing in-situ observation of electron irradiation in high-voltage electron microscopy (HVEM). Fine black spot defects, which seemed to be dislocation loops were observed at irradiation temperature ranging between RT and 373 K in Cu–Cr–Zr, Cu–Cr and GlidCop Al–60 alloys with low number density. In Cu–Cr, loops formed on a part of precipitates interfaces. Hence, a part of precipitate/matrix interfaces is a sink with interstitial bias. Whereas, most of the interfaces are neutral sinks for point defects. In the case of Cu–Cr–Zr and GlidCop Al–60, black spots formed around dislocation, which were induced during two-step heat treatment. The results showed that the precipitate/matrix interface of Cr-rich precipitates in Cu alloys serve as a strong sink for point defects.

    We show that Xe ion irradiation with 80 MeV to GdBa2Cu3O y -coated conductors creates different morphologies of columnar defects (CDs) depending on the irradiation angles θ i relative to the c-axis: continuous CDs with a larger diameter are formed for oblique irradiation at θ i = 45°, whereas the same ion beam at a different angle (θ i = 0°) induces the formation of discontinuous CDs. The direction-dependent morphologies of CDs significantly affect the angular behavior of the critical current density J c. In particular, low-energy irradiation defects induce further improvement of J c in a unique combination of irradiation angles of θ i = 0° and ±45°: discontinuous CDs at θ i = 0° and crossed CDs at θ i = ±45° provide correlated pinning in a wide angular range, which is more strongly enhanced by each other via the pinning of kinks.

    Reflection spectra of cerium dioxide sintered samples were measured in the UV-visible range after irradiation with various heavy ions (2.4-MeV Cu, 5-MeV W, 10-MeV W, 36-MeV W, 100-MeV Kr, and 200-MeV Xe). Differential reflectance spectra of irradiated samples after subtraction of the reference sample spectrum are fit with six broad Gaussian bands centered at about 1.2, 2.2, 2.8, 4.0, 4.8, and 6.2 eV. The growth curves of most bands show a saturation behavior vs ion fluence. Reflection spectra are consistent with the UV-visible absorption spectra of electron-irradiated ceria single crystals for photon energies lower than 3.2 eV, corresponding to the optical gap. The spectra are tentatively analyzed on the basis of charge transfer bands and the 4f-5d transitions related to the Ce3+ ions in the distorted environment formed by irradiation. More insight into defect formation is given by the reflection spectra rather than the absorption ones due to the limitation in the absorption of the optical gap. These data are also discussed with reference to the radiation damage processes by electronic excitations and nuclear collisions in ceria.

    Dislocation loops in NiCo and NiFe, both being single-phase, equimolar solid solution alloys, are generated by in situ high-voltage electron irradiation and characterized inside a transmission electron microscope. In addition to the different defect growth rates, the two alloys present dislocation loops with distinct shape evolution and element segregation, which reflect the element-sensitive, intrinsic properties (e.g., defect energetics, lattice distortion, and local ordering) of the alloys. These results provide evidence that the structure and dynamics of radiation-induced defects in concentrated alloys depend on not only the number but also the species of alloying elements.

    UV-visible absorption spectroscopy and Raman spectroscopy were used to study damage production in cerium dioxide epitaxial films and polycrystalline sintered samples after irradiation with electrons for three energies to span the threshold displacement energies of cerium and oxygen atoms, and 2.4-MeV Cu ions. Neither amorphization nor specific colour-centre bands were detected. Evolutions of the refractive index were derived from the interference fringes in the optical transmission spectra of epilayers after irradiation. No significant change of the refractive index occurred for the 1.0-MeV electron irradiation, whereas a maximum decrease by 28 ± 8% was deduced for the 1.4-MeV and 2.5-MeV energies. These modifications are consistent with ballistic damage on the cerium sublattice for high electron energies producing Ce 3+ ions. However, no significant change of refractive index was found for the Cu ion irradiation. This likely stems from the high rate of Frenkel pair recombination in the collision cascades induced by more energetic recoils than for the electron irradiations, combined with electronic excitations and hole capture on Ce 3+ ions. This study reveals modifications of the electronic structure upon irradiation that could take place in other non-amorphizable oxide systems.

    We have studied the formation of color centers in magnesium aluminate spinel (MgAl2O4) by X-ray
    and electron irradiations near room temperature (RT). For this purpose, Cu Kα radiation and three
    electron energies (1.0, 1.4, and 2.5MeV) were used for variable fluences (up to 4.2 × 1018 cm−2). Offline
    UV-visible absorption spectra were recorded at RT as well as at low temperature down to 27K after electron irradiation. The dependence of the production rate of F centers (oxygen vacancies) on the electron energy yields a threshold displacement energy of 190 ± 10 eV for oxygen atoms at RT, which is much higher than the determinations by molecular-dynamics simulations. Such a discrepancyis discussed on the basis of available migration data of point defects in spinel. Equipartition of F0 and F+ centers, i.e., the neutral (VO x ) and singly ionized (VO . ) oxygen vacancies, is reached for high electron fluences. Moreover, the evolution of the width of color-center absorption bands versus temperature is interpreted with the classical theory for F centers (neutral halogen vacancies) in alkali halides. The Stokes shifts are deduced from the temperature dependence of the absorption bandwidths of color centers like for alkali halides and alkaline-earth oxides. Finally, isothermal annealing data for long annealing time show a non-zero asymptotic behavior for both F0 and F+ centers. This uncommon behavior is interpreted by charge exchange processes leading to an equilibrium state between those two color centers.

    The cathodoluminescence (CL) induced in four oxide single crystals (α-Al2O3, ZrO2: Y or YSZ, MgAl2O4, and TiO2) by high-energy electrons from 400 keV to 1250 keV was studied as a function of beam parameters (flux and energy). The main CL bands are related to F center (oxygen vacancy) formation by elastic collisions above the threshold displacement energy of oxygen atoms. The beam-intensity dependence is interpreted on the basis of a kinetic-rate model involving F-center formation and annihilation. The temperature effect was also followed from 110 K to 300 K. A broad maximum is found for all bands at about 200 K for sapphire, whereas a monotonous increase with temperature is observed for YSZ. The plots of CL intensity versus temperature are mainly interpreted by the interplay between the thermal dependence of thermalized free-carrier trapping rates and luminescence efficiency. Finally, the dependence of CL intensity on the primary electron energy for F centers in YSZ showing a maximum at about 600 keV is explained on the basis of the interplay between point-defect formation and secondary-electron energy spectra production.

    Cationic disorder in MgAl2O4 spinel induced by swift heavy ions was investigated using X-ray absorption near edge structure.With changes of the irradiation fluences of 200 MeV Xe ions, the Mg K-edge and Al K-edge spectra were synchronouslychanged. The calculated spectra based on density function theory indicate that the change in experimental spectra weredue to cation disordering between Mg in tetrahedral sites and Al in octahedral sites. These results suggest a high inversiondegree to the extent that completely random configuration is achieved in MgAl2O4 induced by the high density electronicexcitation under swift heavy ion irradiation.

    The damage induced in cerium dioxide by swift heavy ion irradiation was studied by micro-Raman
    spectroscopy. For this purpose, polycrystalline sintered pellets were irradiated by 100-MeV Kr,
    200-MeV Xe, 10-MeV, and 36-MeV W ions in a wide range of fluence and stopping power (up to
    28MeV lm1). No amorphization of ceria was found whatsoever, as shown by the presence of
    the peak of Raman-active T2g mode (centered at 467 cm1) of the cubic fluorite structure for all
    irradiation conditions. However, a clear decrease of the T2g mode peak intensity was observed as a
    function of ion fluence to an asymptotic relative value of about 45%. Similar decays were also
    observed for satellite peaks and second-order peaks. Track radii deduced from the decay kinetics
    for the 36-MeV W ion data are in good agreement with previous determinations by X-ray diffraction
    and reproduced by the inelastic thermal spike model for low ion velocities. However, interaction
    between the nuclear and electronic stopping powers is needed to describe the decay kinetics of
    10-MeV W ion data by the thermal spike process. Moreover, the asymmetrical broadening of the
    main T2g peak after irradiation was analyzed with different theoretical models. Published by AIP

    Language:English   Book type:Scholarly book

    Irradiation with energetic particles induces elastic displacement damage and electronic excitation in ceramic compounds, and evolve microstructure change. In this article, three types of ceramic compounds, (1) fluorite-type oxides (such as yttria stabilized cubic zirconia (YSZ), urania, and ceria), (2) silicon carbide, and (3) normal spinel structure oxides (such as magnesium aluminate spinel), were selected to provide their defect formation, accumulation, and microstructure evolution. All of these ceramics are of importance for nuclear applications, but have different nature of chemical bonding and structural complexity. This article clearly shows that the dimensional stability (swelling caused by the accumulation of point defects, amorphization, and the formation of voids) and the mechanical property change (nano-indentation hardness and elastic constant) are significantly different among the ceramics due to the difference in the recombination behavior of point defects, stability of defects including exchange at the anti-sites, response to electronic excitation, and so on, through a variety of experimental and computational techniques.

    Oxide ceramics, such as ceria, yttria-stabilized zirconia, magnesiumaluminate spinel, are of importance for nuclear applications because of their superior resistance to amorphization. Radiation damage induced by fission fragments (FFs) is the most crucial issue for fuel and target aterials, in which high-density electronic excitation is induced to form continuous ion tracks. This paper reports the structure of ion tracks in those oxides throurgh a variety of transmission electron microscopy (TEM) and scanning transmission electron microscopy (STEM) techniques, to discuss the atomic structure of ion tracks and microstructure evolution at high dose. Atomic resolution STEM observations showed that core damage regions of ion tracks for oxides, CeO2, yttria-stabilized ZrO2 and MgAl2O4, maintain their own crystal structure. The atomic density in core region of ion tracks is, however, depressed and oxygen sublattice is preferentially disordered in fluorite oxides (CeO2, yttria-stabilized ZrO2). Modelling of the accumulation of ion tracks against ion fluence succeeded in evaluation of ion tracks size, size of recovery region, and track formation efficiency. Those values were discussed as a function of electronic stopping power among the oxides. References [1] S. Takaki et al., Nucl. Instrum. Meth. B, 326 (2014) 140. [2] K. Yasuda et al., Int. J. Mater.

    感覚代行装置は,60年代に開発された視触覚代行技術(TVSS:tactile vision substitution system)を端緒としており,このシステムは全盲者に対して物体形状を背中に振動呈示するものであった.これらの取り組みは実用までには至らなかったが,感覚代行の特質を説明する多くの知見が得られた.近年では,より精巧な刺激呈示器・小型センサを用いた研究開発が進展しており,行動学的検証,感覚間可塑性に関わる脳機能イメージング解析等が行われている.この原理や技術は,運動制御や学習を扱うリハビリテーション分野への展開も進んでおり,著者らは脳卒中感覚麻痺の補完を意図した体性感覚型バイオフィードバックシステムに応用してきた.本稿では,各階層で進行している研究成果を概観しつつ,著者らが取り組んでいる姿勢や歩行を対象としたバイオフィードバック技術について解説する.(著者抄録)

    半側空間無視(USN)は,大脳半球病巣と反対側の刺激を発見・報告すること,反応すること,向くことの障害である.また,右半球における脳血管障害患者の約4割がUSNを併発し,後遺症のリハビリテーションが困難となる.筆者らは,バーチャルリアリティ(VR)技術を用いて,USN患者における無視領域を3次元的にマッピング化する技術を開発してきた.本システムの特徴は,無視症状が乖離するとされる近位(身体近傍空間)・遠位(身体外空間)について,3次元的に無視領域をマップ化し,VR内の視覚誘導により,無視側へ認識できる領域を拡大させていくことである.本稿では,近年,リハビリテーション分野への応用が進んでいるVR技術について,筆者らの研究開発事例を基に概説する.(著者抄録)

    本領域研究は、有機合成に破壊的イノベーションを起こすデジタル有機合成(実験科学と情報科学の異分野融合)の基盤を世界に先んじて築くことを目的とし、有機合成の多様性に対応した独自のデジタル化プラットフォーム(PF)を構築する。A01班、A02班、A03班の3班体制で、人工知能(AI)を徹底活用した自動化法(分子構造自動設計、合成経路自動探索、反応条件自動最適化、バッチ→フロー自動変換、自律的自動合成システム)でムダを徹底排除し、革新反応・革新分子創出の超加速化を実現するとともに、自動化法開発の基盤となる、有機化学の機械学習に最適化した本領域独自のデータベース(DB)の構築を行う。
    情報科学(機械学習)によるアプローチは、人間が実験科学を通じて行うのと同じ帰納的アプローチであり、極めて利用価値が高いと期待されるものの、有機化学への機械学習の利用は極めて限定的で、いまだ未発達である。そこで、本計画研究では、革新反応開発に機械学習を徹底活用(実験科学と情報科学の異分野融合)することで、化学選択性の触媒制御法開発の超加速を実現し、その基礎となる官能基標的触媒を網羅的に創出することを目的とし、(1)機械学習による反応条件最適化の超加速、(2)官能基評価キット活用による化学選択性の網羅的データ集積、(3)機械学習による新反応制御因子の顕在化、(4)機械学習によりデザインされた革新分子の合成と評価、(5)開発した革新反応の反応モジュール化とフロー反応での活用の検討を行う。R3年度(6ヶ月間)は主に以下の検討を行った。
    (1)実験化学者が日常の研究生活の中で機械学習を取り入れながら研究を行うことができるよう、研究環境の整備を行なった。①電子実験ノートを導入し、全ての実験結果を電子実験ノートに集約するシステムの構築を行なった。②ベイズ最適化を行うためのPythonの利用環境を構築し、勉強会を複数回実施した。③機械学習の説明変数として利用するための量子化学計算の環境整備と勉強会を行った。④①から③の環境整備を基盤に、連続型変数のベイズ最適化を活用した反応条件最適化を行った。④離散型変数、特に溶媒効果の機械学習による最適化を促進するための検討を行なった。
    (2)総括班で構築した官能基評価キットを活用し、官能基の反応に与える影響の網羅的情報収集を行なった。
    (4)デジタル創薬の共同研究体制を構築し、情報科学によって提案された化合物の合成と生物活性評価を行った。
    (5)フロー合成装置を導入し、大量の高品質データを容易に得ることを可能とする、システム構築を行なった。
    (1)まず、実験化学者が日常の研究生活の中で機械学習を取り入れながら研究を行うことができるよう、研究環境の整備を行なった。具体的には、電子実験ノートの導入、ベイズ最適化を行うためのPythonの利用環境を構築、量子化学計算利用の環境整備を行った。続いて、連続型変数(時間、温度、試薬の当量比など)のベイズ最適化中心に検討し、新規触媒反応の反応条件最適化に活用した。一方で、反応条件の最適化には、溶媒効果や触媒構造などのデジタル化が困難な離散型変数の最適化も重要であり、それらの離散型変数をどのようにデジタル化するかの検討を行った。溶媒効果に関しては、実測及び量子化学計算によって得られた物理化学的パラメータの活用や、Fingerprintを活用した手法などを検討し、イミン合成反応などにおいて最適溶媒の提案に成功した。今後様々な手法の開発を行なっていく予定である。触媒構造に関しては、遷移状態モデルを活用した機械学習の検討を行っている。
    (2)総括班で構築した官能基評価キットを活用し、20種類以上の官能基の、反応に与える影響の網羅的情報収集を行なった結果、ある程度予想された官能基許容性とともに、これまで影響がないと思われていた官能基の多くで、反応速度を低下させる負の添加影響があることが判明した。また、幾つかの官能基で予想外の正の添加効果も確認されており、これは、今後、(3)の新反応制御因子の顕在化につながる結果である。一方、データベース化するためには、情報の信頼性を確保する必要があり、統計的手法を取り入れる必要があり、次年度以降の検討課題とした。
    (4)PPI阻害剤をターゲットとした低分子化合物のデジタル創薬研究を実施し、情報科学によって提案された化合物の合成と生物活性評価を行った。(5)電解フロー反応の最適化をベイズ最適化の手法を用いることで、極めて少ない実験数で達成した。
    R4年度はR3年度の検討結果をもとに、(1)から(5)の項目に関して、以下の検討を行う。
    (1)総括班として機械学習の教育用動画を作成するとともに、機械学習をチュートリアル形式で学ぶ若手勉強会を年に数回程度実施する。電子実験ノートから領域データベースへのデータ提供を簡便に行うためのAPIを作成する。また、電子実験ノートを利用していない班員のために、webからの入力により簡単にデータベース提出用のデータを作成するシステムを作る。また、領域のデータベースの運用を開始する。(2)官能基評価キットを活用した化学選択性の網羅的情報収集において、統計的手法を取り入れたより信頼性の高い手法を構築し、多くの班員が評価キットを利用することで、さらに多くの反応の化学選択性の網羅的情報収集を行う。反応の種類を拡張するとともに、見い出した正の添加効果に関して精査し、新たな触媒系の開発につなげる。(3)計算科学と情報科学を融合させ、代表的な不斉金属触媒、不斉有機触媒の特徴量を網羅したデータベースを構築する。それらを用いた機械学習を行うことで、不斉触媒反応の主制御因子の顕在化を行う。(4)現在進めているデジタル創薬に関する共同研究をさらに推進する。特に、機械学習によって提案された創薬リードの合成と生物活性評価を推進する。(5)バッチ反応のフロー反応化を推進するために、固相担持触媒反応、電解フロー反応、光フロー反応などの検討を加速する。

    酸化物/窒化物セラミックスは,核燃料や核変換処理材料として期待される重要な原子力材料であり,線質やエネルギーが異なる種々の放射線の複合照射環境に置かれる。その照射損傷発達過程を理解するためには,複合照射損傷,すなわち高密度電子励起損傷とはじき出し損傷(格子励起損傷)の同時・重畳効果(シナジー効果)を点欠陥挙動の立場から明らかにすることが不可欠である。本研究では電子顕微鏡法ならびに放射光分光法を用いて,微細構造発達に及ぼす電子励起/格子励起のシナジー効果を点欠陥挙動の立場から追及し,微細組織発達過程が個々の放射線損傷の足し算とならないことを明らかにしていく。
