Profile
Yoshihiro Yamazaki's researches in Advanced Functional Inorganic Materials Research Division focus on the multiple length scale ion, electron and electronic-hole transport characterization in metal oxides aiming for efficient solar-fuel and energy conversions. One of ultimate challenges in materials science is to activate a useful materials fuction for a specific application. In particular, the production of efficient solar fuel in conjunction with inorganic materials makes use of unlimited solar energy even at night. A challenge is to unravel critical material and architectural paramters, in a wide range from sub-nanometer to macroscopic scale, that activate such energy functions. We combine materials synthesis, electrochemical spectroscopy, mass-spectroscopy, thermogravimetry and in-situ high-temperature solid-state NMR, and correlate them to energy functions in inorganic materials. The research topics include novel catalytic oxides for solar-driven thermochemical fuel production and proton transport in proton-conducting oxide.

     More details

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

    The influence of NiO, used as a sintering aid, on the transport properties of BaZr0.8Y0.2O3 - Δ was investigated by monitoring electrical conductivity relaxation of specimens with and without NiO during hydration in atmospheres of different oxygen activities at 700 and 800 °C. The chemical diffusivities of H and O governing the kinetics were precisely evaluated from the transient conductivity, and all the defect-chemical parameters - the two external equilibrium constants and mobilities of all the carriers, VO· ·, Hi· and h· - were determined from the steady-state equilibrium conductivity. It is found that the processing benefits afforded by NiO are accompanied by a significant reduction in ionic mobilities and hydration reaction constant. These factors, in turn, result in a smaller electrolytic regime in the presence of NiO than when it is absent.

    We demonstrate that solid-state NMR spectra of challenging nuclei with a low gyromagnetic ratio such as yttrium-89 can be acquired quickly with indirect dynamic nuclear polarization (DNP) methods. Proton to 89Y cross polarization (CP) magic angle spinning (MAS) spectra of Y3+ in a frozen aqueous solution were acquired in minutes using the AMUPol biradical as a polarizing agent. Subsequently, the detection of the 89Y and 1H NMR signals from technologically important hydrated yttrium-doped zirconate ceramics, in combination with DFT calculations, allows the local yttrium and proton environments present in these protonic conductors to be detected and assigned to different hydrogen-bonded environments.

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

    Tracer diffusion coefficients of 67Cu and 64Cu in CVD β-Silicon carbide (β-SiC) have been measured in the temperature range between 623 and 1373 K by use of a serial ion-beam sputter-microsectioning technique. The temperature dependence of the diffusion coefficient D is expressed by DCu* = 8 . 2- 0.5+ 0.5 × 1 0- 16 exp (- 41 ± 1 kJ mol- 1 / RT) m2 s- 1 . The diffusion coefficient of Cu in β-SiC is larger than those of Si and C by more than six orders of magnitude and those of Fe and Cr by one-three orders of magnitude. The activation energy for the diffusion of Cu is about one twentieth of that for the self-diffusion. The results suggest that an interstitial mechanism operates on the diffusion of Cu in β-SiC.

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

    Tracer diffusion coefficient of 181W in -iron has been determined in the temperature range between 833 and 1173 K using a serial sputter-microsectioning method. The temperature dependence of the diffusion coefficient, D, over the whole temperature range of -iron across the Curie temperature (TC = 1043 K), can be expressed by [image omitted] where s is the ratio of the spontaneous magnetization at T K to that at 0 K. The factor 0.086 in the above equation is smaller than 0.156 for the self-diffusion, showing that the influence of the magnetic transformation on the diffusion of tungsten in -iron is smaller than that on the self-diffusion. The activation energy 287 kJ/mol for tungsten diffusion in the paramagnetic iron is much higher than 250.6 kJ/mol for the self-diffusion. Atomic size effect is predominant in the activation energies for diffusion of transition elements in the paramagnetic -iron.

     More details

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

    The diffusion coefficients of Au, DAu*, in γ-Fe in the temperature range from 1263 to 1653 K at 0.1 MPa Ar and from 1207 to 1351 K at 3-5 GPa H2 have been determined by relating the interdiffusion coefficients in single-phase Fe/Fe-Au couples with the Darken-Manning relation. The value of DAu* in γ-Fe at 5 GPa H2 is 2-3 times larger than that at 0.1 MPa Ar. The temperature dependence of D Au* in γ-Fe at 0.1 MPa Ar and at 5 GPa H2 can be expressed as DAu*=8.1-2.3 +3.2×10-5exp{-(290±4)kJmol-1/RT} m2 s-1 and DAu*=1.4×10 -3exp(-310kJmol-1/RT) m2 s-1, respectively. The value of the activation energy at 5 GPa H2 is 20 kJ mol-1 larger than that at 0.1 MPa Ar, whereas the value of the pre-exponential factor at 5 GPa H2 is 17 times larger than that at 0.1 MPa Ar. Therefore, the enhancement of the diffusion at 5 GPa H2 is attributed to a high value of activation entropy.

    Tracer diffusion coefficient of molybdenum in α-iron was determined in the temperature range between 833 and 1163 K by using a serial sputter-microsectioning technique. The temperature dependence of the diffusion coefficient, D, in the whole temperature range of α-iron across the Curie temperature was found out. Results showed that the influence of the magnetic transformation on the diffusion of molybdenum in α-iron was smaller than that on the self-diffusion as expected from the negative magnetic moment of molybdenum.

     More details

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

    Impurity tracer diffusion of 59Fe, 51Cr and 57Co in CVD β-SiC has been studied in the temperature range between 973 and 1873 K. The temperature dependence of the volume diffusion coefficients of iron and chromium can be expressed by linear Arrhenius equations. The preexponential factor and the activation energy are estimated to be 8.7 × 10-15 m2 s-1 and 111 kJ mol-1 for iron, respectively, and 9.5 × 10-15 m2 s-1 and 81 kJ mol-1 for chromium, respectively. The diffusion coefficients of iron and chromium are much higher than those of the self-diffusion in β-SiC. Furthermore, the activation energies for the diffusion of iron and chromium are about one-tenth of those for carbon and silicon in β-SiC. Therefore, it seems that an interstitial mechanism is predominant for the diffusion of iron and chromium in β-SiC. On the other hand, the diffusion coefficient of cobalt above 1673 K is higher than that of iron, while at lower temperatures it is much lower than that of iron. The difference in the diffusion coefficients at 1173 K is more than three orders of magnitude. Thus, the temperature dependence of the diffusion coefficients of cobalt shows a strongly curved Arrhenius relation. This suggests that cobalt atoms diffuse by an interstitial mechanism at higher temperatures and by a substitutional mechanism at lower temperatures. From the deeper regions of the penetration profiles of iron, chromium and cobalt the dislocation diffusion coefficients of them have been estimated.

  • 平成30年度 戦略的創造研究推進事業(CREST)に採択される。研究課題「実験と計算科学の融合による革新的プロトン伝導性無機化合物の創製」

    2018.10

     More details

    本研究の目標は、実験と理論・計算・データ科学を融合したプロトン伝導性無機化合物とそれに適した電極材料の創製手法を開発し、中温度域(300〜450℃)において0.01S/cm以上の高いプロトン伝導度と高い安定性を兼ね備えた革新的プロトン伝導性無機化合物及びそれを用いた革新的プロトン伝導性デバイスを創製することである。実験データと理論計算を活用したバーチャルまたは理論的材料スクリーニングにより、革新的無機材料やデバイスの開発スピードを劇的に加速させることを狙う。

  • 科学技術振興機構さきがけ「光エネルギーと物質変換」(2010~2016)の援助のもと、大挑戦型の研究『太陽光と新規酸素吸収酸化物を用いた燃料生成』を推進。プロトン伝導を誘起した金属酸化物において世界で初めてプロトン伝導機構を解明し、Nature Materials 紙に発表した。九州大学に異動後、さきがけ研究前半までの金属酸化物を化学反応場とする研究実績を基礎にペロブスカイト型金属酸化部の非化学非量論性に着目した反応性制御の視点による先見的な研究戦略をさらに精査充実させていっそうの積極的研究展開を図っている。これらの業績を踏まえて、2017年12月に戦略的国際共同研究プログラム(SICORP)のアドバイザーに就任した。

Outline of Social Contribution and International Cooperation activities

  • 1 カリフォルニア工科大学の夏期学部研究奨学生の選考委員として研究プロポーザルを選考し、世界中の優秀な学部生に米国カリフォルニア工科大学にて世界最先端の研究を行う機会を与えた(2013年3月、2010年3月)。カリフォルニア工科大学では米国のみならず世界中から毎年200名程度の夏期研究奨学生を受け入れているが、そのうち7つの研究プロポーザルについて順位付けを行い、プロポーザル内容についてコメントした。この結果を受けて5、6名の学部研究奨学生が受け入れられた。
    2 Nature Materials論文出版にあたり行われた計5件のプレスリリースや新聞発表を通じ、世界最先端の研究成果を社会に周知した(2013年5月)。
    3 東北地方太平洋沖地震に際し、ソーシャルメディアを通じ日本への募金を呼びかけた(2011年3月)。
    4 九州大学稲盛フロンティアセンター、また西新プラザにてSolid-state Chemistry & Ionics (SCI) workshopを開催した。(1st 2016.11.16、2nd 2016.12.20、3rd 2017.11.7、4th 2018.6.15、5th 2018.9.10~13)国内外の研究者が参加している。
