㸯㸬Structural Engineering of Graphene-Based Frameworks
High-temperature annealing (~1800 °C) is often used to enhance the crystallinity and eliminate the O- and Hterminal functional groups of graphene-based nanocarbon materials. However, most nanocarbons encounter
severe structural change at such a high temperature. Over the past one year, we tried to elucidate the crucial
structural factors that determine the thermal stability of graphene-based nanocarbon materials.
We defined the structure retention degree (SRD) based on the change in the basal plane sur-face area ofnanocarbons when they are subjected to heat treatment at 1800 °C. The larger the amount of graphene-stacking
structure becomes, the lower the SRD becomes. Additionally, we differentiated two types of stacking structures,i.e., tight stacking and loose stacking. The tight stacking is formed by the bottom-up growth of graphene during
the chemical vapor deposition process, whereas the loose stacking is generated by capillary shrinkage after
template removal. We found that loosely stacked
structures triggered extra stackings via the epitaxial
effect at high temperatures (Fig. 1). Moreover, wedemonstrated that the threshold of the inner space sizethat triggers the thermal-induced structural change isabout 4-7 nm. These results offer a fundamental
understanding

of

the

solid-statechemistry

nanocarbons under thermal annealing, andfor engineering graphene-based frameworks.

第 21 回東北大中性子セミナー・第 31 回 QLC セミナー
・第 22 回ハイパーマテリアルセミナー
日 時 ： 2022 年 06 月 17 日
場 所 ： 東北大学多元物質科学研究所 西一号館 2 階セミナー室
講演者 ： Marc de Boissieu (Université Grenoble Alpes, CNRS, SIMaP, Grenoble France)
題 目 ： Thermal conductivity and lattice dynamics in structurally complex materials
要旨：

The lattice thermal conductivity of many diﬀerent materials are displaying a ‘glass like behavior’ [1], with a relatively
small value of the lattice thermal conductivity at ambient temperature and an almost independent temperature dependence
in the range 20 to 300 K. This is the case for disordered crystals [1], for clatharates [2], but also for aperiodic crystals [3]such as the icosahedral quasicrystal i-AlPdMn [4], and the Rb2ZnCl4 phase that displays an incommensurately modulated
phase between 190 and 300 K [5]. The detailed understanding of this behavior and the relationship between the phonon
spectrum/phonon lifetime and the thermal conductivity is still a matter of debate.
In this presentation I will introduce the two main aspects of structural complexity, namely number of atom in the unit
cell and disorder. On one hand, the structural complexity may be characterized by the number of atoms in the unit cell,which goes to inﬁnity in the case of aperiodic crystals. On the other hand disorder may occur as chemical site disorder
or lattice displacement. By reviewing some recent results in this ﬁeld I will show the relative importance of structure anddisorder [6]. A simple model of a phonon lattice gaz, as developed for Ge based clathrates [2] will be used to interpret
some of the data.

参加学生の学年別の内訳は、大学院生が 9 割、学部生が 1 割だった。専攻別では、マテリアル・開発系が 8 割、環境科学研究科が 2 割だった。
セミナー受講前後で、非鉄金属製錬業界への関心度は変わらなかった。元々関心のある学生が大半だった。
セミナーを通じて企業における現状の課題などを伝えることができた。工場見学が困難な状況で、擬似的な工場見学の機会が得られたことが良かった、現場技術者の話を聞く機会が持てて良かった、とする感想が多くあった。完成した技術と考えていた銅製錬にもまだまだ改善すべきところがあると知って興味深かったとの感想もあり、できるだけ多くの学生に非鉄金属製錬について知ってもらうという共同研究部門の目的の一つを果たすことができた。

第１回無機材料研究部門講演会
日 時 ： 2022 年 10 月 7 日（金）10:00〜11:30
場 所 ： 東北大学片平キャンパス 材物棟 1F 大会議室
（コロナ禍による定員 24 名）
講 師 ： Prof. Richard Dronskowski
無機材料研究部門 客員教授（2022.9.20 ‒ 12.20）(Chair of Solid-State and Quantum Chemistry)(RWTH Aachen University, Aachen, Germany)
講演題目 ： The Crystal Structure of Carbonic Acid
主 催 ： 無機材料研究部門
参加者 ： 22 名
講演要旨：Ubiquitous carbonic acid, H2CO3, a key molecule in biochemistry, geochemistry, and also extraterrestrial

chemistry, is known, at least in principle, from various physicochemical studies but is often considered, even up to thepresent day, a somewhat mysterious

non-existing

molecule. In fact, the molecule has never been directly seen, thereason being that high pressure is needed to stabilize it, as easily shown by electronic-structure theory. After an eightyears research study, the crystal structure of carbonic acid has now been determined from neutron-diﬀraction data on a
deuterated sample in a specially built hybrid clamped cell using

Russian alloy . At 1.85 GPa, D2CO3 crystallizes in

the monoclinic space group P21/c with a = 5.392(2), b = 6.661(4), c = 5.690(1) Å, β = 92.66(3)° , Z = 4, with one
symmetry-inequivalent anti-anti shaped D2CO3 molecule forming dimers, as previously predicted. Quantum chemistryevidences π bonding within the CO3 molecular core, very strong hydrogen bonding between the molecules, and a massivein ﬂ uence of the crystal ﬁ eld on all bonds; phonon calculations emphasize the locality of the vibrations, being rather
insensitive to the extended structure. Now that carbonic acid has been ﬁrmly established, this may be important for otherﬁelds, for example CO2

sequestrationand its the chemical consequences. Likewise, carbonic acid probably plays

a role in our solar system, say, on outer gas planets such as Uranus or Neptune and, also, on the Jupiter moon Europa.
Finally, many chemistry textbooks must be rewritten because the simplest molecule consisting of water and carbon dioxide
actually exists.

マテリアル・計測ハイブリッド研究センター講演会
日 時 ： 2022 年 10 月 11 日（火）15:00〜16:30
場 所 ： 東北大学片平キャンパス 東 2 号館 2F セミナー室※オンサイト開催（定員 18 名）
講 師 ： Teresa J. Bandosz 教授（The City College of The City University New York)
題 目 ： Beyond Adsorption and Because of Adsorption: Exploring the silent aspect of carbon poros-ity
要 旨 ： In this talk we would like to provide an insight into our perspectives on the new applica-

tions of nanoporous carbons that were inspired by the graphene features and its presencein these carbonaceous materials. A signiﬁcant advancement to the
old

new

science of thenanoporous carbons is in their new application such as gas sensing and ORR and

CO2RR catalysis. In these applications both surface chemistry and porosity are crucial factors determining the speciﬁc performance. The mechanism of speciﬁc processes based on
an involvement of porosity will be proposed. Our inspiration by the science of graphene
combined with the comprehensive knowledge of activated carbons surface chemistry, texture, morphology and adsorptive/reactive adsorptive properties directed us to look at carbons
from another perspective; from the perspective of nanotechnology. The results obtained by
us and brieﬂy addressed here are new and many questions have arisen, and are left unanswered, and many approaches need improvements. One has to take into consideration that
explaining the complex phenomena in nanoporous carbons is not easy owing to the combination of the porosity and surface chemistry eﬀects. Practically either one cannot exist
without another and they add up to that’s speciﬁc and unique synergy provided only bythese materials. One thing is certainly true:

adventurous

graphene features can be foundin nanoporous carbons and they deserve to be explored and used to their full extent.

第 22 回東北大中性子セミナー
日 時 ： 2022 年 10 月 13 日 (木) 15 時
場 所 ： 東北大学多元物質科学研究所 西一号館 大会議室
講演者 ： Maxim Avdeev (ANSTO)
題 目 ： Atomistic modelling as a complementary tool for diﬀraction studies
要 旨 ： Diﬀraction experiments typically provide clear picture of a crystal structure and basis forunderstanding material properties. However, for data of poor quality or in case of materials
with high static or dynamic disorder and/or weakly occupied atomic sites, diﬀraction may
struggle to distinguish several alternative models yielding similar χ2. In that case, atomistic
modelling may be very useful to identify the correct model. I will present several recent
examples of studies of disordered oxide-ion and cation conductors, where empirical and abinitio static and geometry optimization calculations and molecular dynamics simulations not
only helped to validate neutron diﬀraction analysis but also revealed the mechanism driving
the disorder.

第 23 回東北大中性子セミナー
日 時 ： 2022 年 10 月 25 日（火）午後 15:00-16:30
場 所 ： 東北大学多元物質科学研究所 西一号館 2 階セミナー室
講演者 ： 池田進

高エネルギー加速器研究機構（KEK）／ KEK ダイアモンドフェロー

題 目 ： Neutron Compton 散乱研究 —開拓と派生—
要 旨1970 年頃、東北大学で世界最初に誕生し、次いで北海道大学でも開発された電子加速器駆動型パルス中性子源の科学技術は、1980 年、世界が競合する中、両大学の協力によって、世界初の陽子加速器駆動型パルス・スポレーション中性子源施設 KENS を KEK に開花させた。KENS では、当時の中性子散乱研究を躍進させる最新の中性子実験装置が開発され、その培われた技術とアイデアは、今日の J-PARC/MLF 施設の礎となっている。

KENS 中性子実験装置の一つが、eV 領域の中性子（eV-neutron）を使って Neutron Compton Scattering(NCS) 研
究を可能とし、超流動 4He 中のボーズ凝縮量 n(0) の直接観測を目指した装置 RAT であった。KENS 中性子源はTOF 法に必要なパルス時間幅の狭い eV-neutron を RAT に供給できたが、超流動 4He の NCS 実験は、当時、未踏の Q>100Å-1 での実施が期待されており、eV 領域の中性子共鳴吸収を利用した新しい中性子分光法の 確立が必須であった。1987 年、RAT はこの問題を克服し、Q>100Å-1 での n(0) の観測に初めて成功した。
その後、この NCS を用いて、水素結合型誘電体の相転移機構、水素貯蔵合金、水素結合メカニズで決定的な役割を持つ水素の基底状態の研究が行われた。さらに、ここで開発された中性子共鳴
吸収法は、凝集体内の元素毎の実効温度 (Teﬀ) を計測できる新しい実験装置（DOG & EZO）を派生させ、元素毎のデバイ温度（θD）の決定や θD の方向依存性の観測、物体内部の温度分布の計測などを可能とさせた。
なお、2006 年、KENS 施設は J-PARC ／ MLF 開設に伴いシャットダウンしたが、NCS 技術は、英国 ISIS 施設で更に改良され、He、

H、Li、Ne、Na、ガラス状態などの研究に活躍している。
KEK より池田進先生をお迎えし、中性子コンプトン散乱に関するセミナーをして頂いた。研究室内外から十数人の参加者に参加頂き、パルス中性子源に関する歴史、共鳴吸収を利用した eV オーダーのエネルギーを有する中性子の分光手法、同手法を利用した水素原子の原子振動の観測結果等に関して議論した。

研究会報告RS-SCJ Net Zero Policy Exchange
Thursday, November 3rd, 2022. 9:30-17:30 (SCJ, Tokyo)
Itaru HONMA (Tohoku), Ryoji KANNO (TIT), Taro HITOSUGI (Tokyo)
Agenda of UK/Japan bilateral scientific dialogue on battery
1. Consider research, development and innovation in these technologies over recent years – what
has worked and what didn’t and why.
Summarized in supplement 1
2. Discuss the major scientific challenges and difficulties that remain, posing barriers to achieving
the net zero target of 2050
‫ ی‬Scientific challenges
1. Devices: High power and high capacity, faster charging, safer, lower cost, longer lifetime.
2. Science & Technology: Battery health monitoring. High throughput experiment/simulation
methods via robotics/supercomputing. Multidimensional nanoscale characterization with higher
time and spatial resolutions. Data -driven exploration of new metastable materials through AI,
deep learning and informatics. Understanding complex system’s physics and chemistry fromnano to micron scale. Modelling of dynamics, nonequilibrium and material interactions undercell operations. Self-healing materials, interfaces and device structures for cell’s longevity.
3. Sustainability: use of recyclable or earth abundant materials, free of critical minerals such as
Li, Co, Ni, etc., to avoid supply chain risks and minimize an environmental impact.
‫ ی‬Barriers to the 2050 target
1. Mass fabrication with reinforced supply chain and low cost, but lower CO2 emissions.
2. Infrastructure of ubiquitous charge stations and grid networks to EV by low electricity rate.
3. Circular economy of used LIB for reuse and recycles to minimize environmental impacts
3. Identify what changes to research, development and innovation (in terms of structure /funding/co-ordination/policy etc.) would facilitate overcoming the challenges identified above.
1. Multidisciplinary research among physics, chemistry, electrical/chemical engineering,materials science and even to mathematics! AI and materials informatics are becoming more
important and helpful for accelerating innovations of novel battery systems.
2. Standardization of the experimental data on crystallographic/optoelectronic analysis,electrode properties, electrochemical analysis and battery performance are necessary for making
versatile and accessible materials big-data base under comprehensive formats.
3. Platform of sharable data base (battery material Genome) for materials informatics, deeplearning and simulations. Vitalization of sleeping data in the individual laboratories around theworld and input those to battery Genome data base, which are supposed to be open access.
4. Internationally collaborated network research from individual laboratories to big scientificfacilities such as synchrotron with bilateral student exchange for human resources development.
4. Where they arise, propose areas where future co-operation between the UK and Japan (atacademic, industrial or governmental levels) could assist in overcoming those barriers.
‫ ی‬Characterization: Further tools need to be developed to probe battery health in batteries
operating in real-life conditions. Better tools are also needed to characterize the materialinteractions within batteries.
Operando CT measurement with a high-3D spatial/time resolution, using quantum beam such assynchrotron hard-/soft-X-ray, electron, and neutron. Operando single particle/thin film model
electrode analysis. STEM analysis of Li, Na, O,,,. Data-driven and AI-assisted device analysis.
‫ ی‬Development of low-cost battery chemistries for very large scale/long period energy storage

Critical minerals’ supply chain risk-free batteries. Using Na, K, Mg, Ca, Zn, Al carrier ions andnot using Li. Using naturally abundant Fe, Mn, etc., and not using Co, Ni for electrodes.
Redox flow and/or other aqueous battery systems. Organic batteries and other novel systems
made by biomass or recyclable resources.

研究会報告125supplement 1
what has worked ?
National R & D bridging programs are proceeding intensively on all solid state LIB employing novel
sulfide electrolytes (prof. R. Kanno) which are expected to be implemented in near-future advanced
EV/PHVs. Alternative choices such as Li-air, Li-S, Mg-battery, Zn-air, fluoride battery and oxidebased all solid state LIB are funded by public programs (NEDO, JST, MEXT).

what didn’t and why?
Small investments on supercapacitors/electrochemical capacitors, redox flow system, aqueous
battery, organic and/or anion redox electrodes, because those are scarcely implemented in EVs.

第 24 回東北大中性子セミナー・第 34 回 QLC セミナー
日 時 ： 2022 年 11 月 16 日（水）午後 15:00-16:30
場 所 ： 東北大学多元物質科学研究所 西一号館

2 階セミナー室

講演者 ： 児玉佑樹（原子力機構中性子センター）
題 目 ： スピン 1/2 三角格子反強磁性体の磁化過程と磁気励起
要旨
スピン 1/2 三角格子反強磁性体 (S=1/2 TLAF) とは三角格子上に局在したスピンが隣接スピンと相互作用する系のことである。三角格子は最もシンプルな二次元格子の一つであるが、S=1/2 TLAF は多彩な量子現象を引き起こす。例えば、磁化過程においては量子ゆらぎの collinear 状態安定化によって磁化プラトー現象 [1, 2] が、磁気励起においては分散関係が極小値を持つ roton-like minimum[3] が確認されている。実験的アプローチから見れば、

S=1/2 TLAF には比較的理想的な候補物質が Ba3 CoSb2 O9 をはじめとしていくつか見つかっている。S=1/2 TLAF
は理論・実験の比較がしやすく量子磁性体の解析手法を洗練するのによい研究対象であるといえる。本発表では、
私のこれまでの研究を中心に、S=1/2 TLAF の候補物質・磁化過程・磁気励起について様々な理論と比較しながら検討を行う。
本発表では主に Ba3 CoSb2 O9 、Ba2 CoTeO6 、Ba2 La2 CoTe2 O12 について紹介する。これらの物質は Neel 温度以下
で S=1/2 TLAF の基底状態の特徴として知られる 120 度構造の磁気秩序状態を示し、磁化過程には幅広い磁化プラ
トーが確認されている [2,4,5]。Ba3 CoSb2 O9 は S=1/2 TLAF の最も一般的な候補物質として知られており、これまで多くの実験が行われてきた。今回の発表では私が最近行った常磁性相における非弾性中性子散乱実験の結果を含めて報告を行う。Ba2 CoTeO6 は S=1/2 TLAF 層とスピン 1/2 ハニカム格子 Ising 型反強磁性層が交互に積層し、それらが独立に振舞うユニークな特徴を持つ [4]。Ba2 CoTeO6 の磁気励起には Ba3 CoSb2 O9 の磁気励起とほとんど同じ
スペクトルが確認され、これらは S=1/2 TLAF に共通した振る舞いであることが示唆される [6]。Ba2 La2 CoTe2 O12は強い容易面型の異方性を持った S=1/2 TLAF であり、S=1/2 TLAF における異方性の効果を検証することのできる数少ない物質である [5]。

日 時 ： 2022 年 12 月 14 日（水）15 時 30 分
場 所 ： 東北大学多元物質科学研究所 西一号館 大会議室
講演者 ： 森山広大（京都大学理学研究科）
題 目 ： 遍歴電子磁性体 SrCo2 (Ge1-x Px )2 におけるスピン揺らぎと量子臨界現象
要旨：

ThCr2 Si2 型構造を有する AT2 X2 は、重い電子系超伝導 (CeCu2 Si2 [1]) や鉄系超伝導 (BaFe2 As2 の固溶系 [2,3]) な
どの多様な物性の舞台として研究が展開されている物質群である。TX4 四面体が稜共有で 2 次元的に連なった TX
層と A 層からなる積層構造を有するが、隣接した TX 層間の X-X 化学結合の有無によって格子定数比 c/a の値が大きく異なり、それぞれ collapsed Tetragonal (cT) 相, uncollapsed Tetragonal (ucT) 相と呼称される。X サイトを 15族元素が占める場合、T サイトが Fe の物質では FeX 層内に反強磁性揺らぎを有することが多いが、T サイトが Coの場合は強磁性揺らぎを有しやすい。中でも、SrCo2 P2 については磁化率の温度依存性におけるピークや遍歴電子
メタ磁性転移などの異常が見られ [4]、擬 2 次元的な強磁性量子臨界点近傍物質として注目を集めている。
本発表では、SrCo2 Ge2 (cT 相) と SrCo2 P2 (ucT 相) の固溶系 SrCo2 (Ge1-x Px )2 の物性を紹介する。多結晶試料を用いた先行研究 [5] によれば、0 ≦ x < 0.325, 0.7 < x ≦ 1 がいずれもパウリ常磁性を示す一方で、0.325 ≦ x ≦ 0.7 では低温で強磁性相が出現し、cT 相と ucT 相のみからなる単純な構造相図からは磁気相図の説明が付かない。我々は CoGe 自己フラックス法を用いることで様々な置換率の単結晶試料の合成に初めて成功し、磁化測定や比熱測定,

31P-NMR 測定などを用いて詳細な物性を調べた。その結果、X-X 化学結合を組む X 元素のランダムネスの影響により cT 相と ucT 相との間に幅広い中間構造相が存在することが判明した。また強磁性の相境界にあたる x=0.39,

0.58 付近については、中間構造相における連続的な構造変化の影響により、低温での磁気比熱が-logT に比例する
量子臨界現象が観測された。発表では本系のスピン揺らぎについて SCR 理論などを用いて解析した結果も交えながら、本系の特異な磁気相図について議論する。
