㸯㸬Catalytic effect of unpaired spins in carbon edge sites
It has been believed that the unpaired spins at carbon edge sites canpromote various catalytic reactions. However, the position of theunpaired spins in carbon materials was not fully clarified. Also, there
has been a lack of quantitative discussion on the relationship between
the number of unpaired spins (Nspin) in carbon materials and catalytic
activity. In this study, we reveal the relationship between Nspin and thenumber of carbon edge sites (Nedge) by using an advanced
temperature-programmed desorption (TPD) technique up to 1800 ႏ
which can precisely determine even a trace amount of edge sites.
Moreover, the relationship between Nspin and catalytic activity was Fig. 1 The relationship between Nedge and Nspin.
Nspin was calculated assuming g factor ofquantitatively investigated using carbon materials with two orders of 2.002319 and the total spin quantum number (S)of 1/2.
magnitude different edge site amounts.

Four kinds of porous carbon materials with different amounts of edge sites were employed as models: zeolitetemplated carbon (ZTC), activated carbon (AC, YP-50F), carbon black (CB, Ketjen Black EC-300J), and graphene
mesosponge (GMS). Nedge of each carbon sample was analyzed by TPD, and Nspin was calculated from its magnetic
susceptibility measured by a SQUID magnetometer. As shown in Fig. 1, a clear correlation was observed between

Nedge and Nspin, which demonstrates that the unpaired spins are located at theedge sites in carbon materials. The ratio of Nspin to Nedge ranged from 0.5 to
1.8 % for all materials.
To investigate the catalytic effect of unpaired spins, dehydrogenativeoxidation of 9,10-dihydroacridine was performed using carbon materials as
catalysts. A positive correlation was found between Nspin and catalytic
activity (Fig. 2), suggesting that unpaired spins in the carbon materials acted
as catalytically active species in the oxidation reaction.
In conclusion, carbon materials with a larger amount of edge sites have ahigher number of unpaired spins, and thus exhibit higher catalytic activity.

㸬Preparation of biocompatible giant hollow carbon tubes (gHCTs)
Carbon nanotubes have great potential in the biological field owing to their high specific area and chemical stability.
However, the poor dispersibility, small inner space, and irregular shape limit their bio-applications. Giant hollow
carbon tubes gHCTs are test-tube-shaped carbon materials with low-crystalline carbon layers. They are prepared byanodic aluminum oxide templated method via chemical vapor deposition. gHCTs have several desirable properties
for bio-applications, such as huge and controllable inner space (range of tube diameter: 25 nm-200 nm, range of tube
length: 0.5 ȝm-100 ȝm) and excellent dispersibility in water. In this research, excellent dispersibility of gHCTs in aphysiological environment was realized after surfactant modification. Additionally, desirable biocompatibility ofgHCTs, including low cytotoxicity and cellular uptake of gHCTs was also observed.
gHCTs with specific size (diameter: 50 nm, tube length shorter than 5 ȝm) were prepared by adjusting theparameters of anodic oxidation. 2 ȝm gHCTs exhibited excellent dispersion stability in water without any posttreatment. However, it is difficult for gHCTs to sustain a stable dispersion in phosphate buffer saline (PBS), which is
widely used in biological fields with high salt concentrations. To address this problem, the biocompatible surfactant(Tween-80: T80) was employed to improve the dispersibility of gHCTs. T80 modified gHCTs (gHCTs @T80)
exhibited excellent dispersibility in PBS even during a continuous dialysis process for one week (Fig. 1b).
Nanomaterials may have the potential risk of cytotoxicity, so we assessed the cytotoxicity of gHCTs with various
length and concentration by using CCK-8. It was found that neither the 2 ȝm gHCTs nor the 0.5ȝm gHCTs exhibited
evident toxicity to HeLa cells even at a high concentration of 100 ȝg/mL, as shown in Fig. 1c. Suspected cellular
uptake behavior of gHCTs was observed by using an optical microscope, and we are confirming for it by using
confocal laser scanning microscope.

題

目： The effect of strong non-magnetic disorder and amorphization in a 3D topological insulator

The sub-classes of quantum insulators can be distinguished using invariants (e.g., Z2) ̶ simple groups
of integers related to the Berry curvature ̶ which also encode information on their distinctive physicalproperties. A special case is the 3D strong topological insulator (TI) having one “strong” index Z2=1,
which is distinct from the normal vacuum (Z2=0). Novel electronic states appear at an interface where
the characteristic invariant Z2 switches from 1 to 0. These conductive states oﬀer prospects for quantum
electronics; however, a method is needed to spatially control Z2 to pattern conducting channels. Recently, we
have discovered that experimentally modifying Sb2Te3 single-crystal surfaces with an ion beam switches thelatter topological insulator into an amorphous state exhibiting negligible bulk and surface conductivity.

The large change in conductivity is concurrent
with a transition from ℤ2 = 1 → ℤ2 = 0 at a threshold disorder strength. This result also

Biography
David Cortie obtained his PhD in physics from the University of Wollongong, whilst based at the Australian
Nuclear Science and Technology Organisation. He then did postdoctoral work at the University of British
Columbia, the Max-Planck Society, the Australian National University and the Australian Nuclear Science andTechnology Organisation. In 2020, he joined the Australian Nuclear Science and Technology Organisation asa neutron scientist specialising in the applications of polarised neutron reﬂectometry. His research focuses on
the interplay between the structure, dynamics, magnetism, and transport phenomena in quantum materials.

工場見学・若手技術者による講義

研究会報告参加学生は、環境科学研究科を中心に、大学院生 5 名、学部生 4 名だった。
久々の現地を訪問するセミナーであり、参加学生も見学、講義にオンライン開催に比較して非常に積極的だった。銅製錬工程
見学では課題を設定し、見学後にグループ
ディスカッションを行う新しいプログラムが設定され、住友金属鉱山セミナー担当者、学生ともに好評であった。工場見学では、オンラインセミナーでは不可能であるニカワや溶媒の匂い、騒音を感じ、
特に工場、装置の大きさを実感できたことは、参加学生にとって大きな収穫であった。
学生に非鉄金属製錬について知ってもらう共同研究部門の目的の一つを果たすことができた。現地での工場見学は、
オンライン開催セミナー
よりも効果の大きい。今後、 出 来 る だ け 多 く の学生が参加するセミナーを開催し、非鉄金属製錬業界の啓蒙活動を継続する。

The 16th Seminar on Nano-Micro Chemical Measurements(GP-Chem Seminar)
Date &Time March 29th, 202, 10:00-11:00
Room
S247, IMRAM West #1 Bldg.
Organic Nanocrystal Enrichment on Paper Analytical Device
Dr. Grasianto,
Lecturer, Department of Chemistry,
Institut Teknologi Sepuluh Nopember (ITS),
Surabaya, Indonesia
Microfluidic paper analytical device (μPADs) is one of the most promising devices dueto their cheapness, ease of use, and simplicity. In this work, I developed an organic
nanocrystal (NCs) enrichment on μPADs for several analyte detections, such as heavy
metal ions, anions, and biogenic amines.

日本顕微鏡学会第 79 回学術講演会
2023 年 6 月 26 日〜 28 日
於：松江市くにびきメッセ
2023 年 6 月 26 日〜 28 日から松江市くにびきメッセにおいて開催された日本顕微鏡学会の第 79 回学術講演会において、「3 次元結晶構造解析の進展」と題したシンポジウムをオーガナイズした。趣旨、講演者、講演タイトルは下記の通りである。

主旨
量子ビームによる結晶回折測定は分子の立体構造を可視化する最も解像度の高い手段である。近年、微小結晶の回折からの電子線三次元結晶構造解析、いわゆる 3D ED、
マイクロ ED と呼ばれる技術が注目を集めた。X 線、中性子線、電子線といった各線種によって特徴づいた情報が得られ、ターゲットも材料化合物からタンパク質複合体まで多岐にわたる。これらに応じて、実験・解析手法自体も多様化・高度化がなされてきた。本シンポジウムでは広く ʼ 結晶構造解析 ʼ をテーマとし、それぞれの最新のアプリケーションや得られる構造情報の扱い、横断・複合利用も含め、構造解析への期待と可能性を議論する。

講演者
玉田 太郎（量研機構）「タンパク質の中性子結晶構造解析の現状と今後」
津田 健治（東北大学）「動力学回折効果を利用した 4D-STEM3 次元構造解析」
平田 邦生（理研）「SPring-8 におけるタンパク質 X 線結晶構造解析の現状と今後」

高場 圭章（理研）「3D ED から得られる構造情報とその利用」

二時間弱の会に 100 名近くの聴講者が集まり、質問や議論も活発で好評を得た。

学生への非鉄金属製錬業の啓発活動、人材育成を目的として、住友金属鉱山共同研究ユニット主催行事として非鉄金属製錬セミナーを開催している。第 1 回は独立行政法人石油天然ガス・金属鉱物資源機構金属資源技術研究所（秋田県鹿角郡小坂町）、第 2 回は住友金属鉱山株式会社東予工場（愛媛県西条市・新居浜市）、三菱
マテリアル株式会社直島製錬所（香川県香川郡直島町）へ訪問して開催した。第 3 回、第 4 回、コロナ禍のため、感染拡大を防止するためオンラインで開催した。第 5 回から現地開催を再開し、住友金属鉱山株式会社東予工場、三井金属鉱業株式会社竹原製煉所（広島県竹原市）を訪問した。第 6 回開催である今回は、住友金属
鉱山株式会社東予工場・ニッケル工場、三菱マテリアル株式会社直島製錬所に訪問した。

参加学生の学年別の内訳は、大学院生、学部生がほぼ半々だった。所属研究室は製錬に関する研究室だけではなく、化学系、地質系の研究室も見受けられる。
セミナー受講前後で、非鉄金属製錬業界への関心度は上がり、6 割強の学生が就職先の候補としたいとアン
ケートで回答した。
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。現地での工場見学は、オンライン開催セミナーよりも効果の大きい。今後、出来るだけ多くの学生が参加するセミナーを開催し、非鉄金属製錬業
界の啓蒙活動を継続する。
