DIAMOND AND RELATED MATERIALS, 11(3-6) 945-948, Mar, 2002 Peer-reviewedThe possibility of H-2 gas storage in fullerene-like materials such as carbon clusters and boron nitride clusters was investigated by molecular dynamics calculations. First principle single point energy calculation was also carried out for C-60 and B36N36 clusters with changing point of H-2 molecule to compare the behavior of H-2 molecules at the tetragonal, pentagonal and hexagonal rings. Molecular dynamics calculations showed that a H-2 molecule remains stable in a C-60 cage at 298 K and 0.1 MPa. It is confirmed that pressures over 5 MPa are needed to store H-2 molecules in the C-60 cage. As a result of single point energy calculations, H-2 molecules enter from hexagonal rings of fullerene-like materials. BN fullerene materials can store H-2 molecules easier than carbon fullerene materials, and has good high temperature stability. (C) 2002 Elsevier Science B.V. All rights reserved.

DIAMOND AND RELATED MATERIALS, 11(3-6) 949-952, Mar, 2002 Peer-reviewedNanoparticles of AlB10, TiN and VN encapsulated by boron nitride (BN) layers were synthesized by an arc-melting method in a N-2/Ar gas mixture from boron/Al powder compacts, TiB2 and VB2, respectively. From high-resolution electron microscopy observations, formation mechanisms of BN nanocapsules were proposed, and BN tube-like structures were also produced. Magnetization of BN nanocapsules with TiN nanoparticles showed a spin-glass-like behavior. The present work indicates that Al, Ti and V could be a good catalyst to produce BN nanocapsules, nanocages and nanotubes by the arc melting method. (C) 2002 Elsevier Science B.V All rights reserved.

DIAMOND AND RELATED MATERIALS, 11(3-6) 935-939, Mar, 2002 Peer-reviewedEndohedral fullerenes Si@C-74 were produced by direct current and radio-frequency hybrid are-discharge. Atomic structure analysis and structural optimization of the Si@C-74 were carried out by high-resolution electron microscopy, image simulation, molecular mechanics and ab initio molecular orbital calculations. Total steric energy of the Si@C-74 was the lowest in the present calculation of C-60-C-76 clusters. The energy gap of the Si@C-74 was calculated to be 0.098 eV, and the heat of formation per carbon atom is almost the same as that of the C-60 Cluster. (C) 2002 Elsevier Science B.V.

DIAMOND AND RELATED MATERIALS, 11(3-6) 940-944, Mar, 2002 Peer-reviewedLa@B36N36 endohedral metallofullerenes were synthesized for the first time, which was observed by high-resolution electron microscopy, and a structure model was proposed. Image simulations of the La@B36N36 clusters also showed the possible existence of a La atom inside the BN clusters. Atomic structures, structural stabilities and electronic structures of La@B36N36, Fe@B36N36 and B36N36 clusters were investigated by molecular mechanics and molecular orbital calculations, which showed that the B36N36 clusters are expanded by introducing doping atoms and the energy gap of B36N36 is reduced by introducing La and Fe atoms inside the B36N36 cluster.

Formation, atomic structures and properties of boron nitride and carbon nanocage fullerene materialsINTERNATIONAL JOURNAL OF INORGANIC MATERIALS, 3(7) 597-612, Nov, 2001 Peer-reviewedVarious boron nitride (BN) and carbon (C) nanocage fullerene materials (clusters, metallofullerenes, onion, nanotubes and nanocapsules) were synthesized by arc-melting, electron-beam irradiation, chemical reaction, and self-organization. Atomic structures and structural stability of these materials were investigated by high-resolution electron microscopy, energy dispersive spectroscopy, electron energy-loss spectroscopy, molecular mechanics, molecular dynamics and molecular orbital calculations. Photoluminescence, magnetic and electronic properties of these fullerene materials were also investigated. The present work indicates that: the new BN and C nanocage fullerene materials with various atomic structures and properties can be produced by various synthesis methods, and a guideline for designing the BN and C fullerene materials is summarized.

Fabcross、Yahooニュース、EEtimes、MONOist、マイナビニュース(TECH+)、日本経済新聞(オンライン版)等, NEDOの「戦略的省エネルギー技術革新プログラム」で「ナノソルダー実用化による製造プロセス省エネ化技術の開発」に取り組むパナソニック ホールディングス(株)は、このたび東北大学、大阪教育大学、秋田大学、芝浦工業大学と共同で、従来よりも低い温度で電子部品を接合でき、接合後はパワーデバイスに必要な耐熱性が得られるナノソルダー接合材料を開発しました。本開発では、低融点金属と高融点金属を組み合わせた固液反応を用いることで、低温かつ短時間プロセスでの接合と200℃耐熱の両立を達成しました。 本開発の成果により、産業機器や電気自動車、鉄道などで使用されるパワーデバイスの組立工程に広く展開することが可能となり、パワーデバイス製造プロセスの省エネルギー化とともにカーボンニュートラルの実現に向けた大きな前進が期待できます。 https://www.nedo.go.jp/news/press/AA5_101549.html, Jun 21, 2022
