Journal ArticleDOI
Helical microtubules of graphitic carbon
TL;DR: Iijima et al. as mentioned in this paper reported the preparation of a new type of finite carbon structure consisting of needle-like tubes, which were produced using an arc-discharge evaporation method similar to that used for fullerene synthesis.
Journal ArticleDOI
Single-shell carbon nanotubes of 1-nm diameter
Sumio Iijima,Toshinari Ichihashi +1 more
TL;DR: In this article, the authors reported the synthesis of abundant single-shell tubes with diameters of about one nanometre, whereas the multi-shell nanotubes are formed on the carbon cathode.
Journal ArticleDOI
Roll-to-roll production of 30-inch graphene films for transparent electrodes
Sukang Bae,Hyeongkeun Kim,Youngbin Lee,Xiangfan Xu,Jaesung Park,Yi Zheng,Jayakumar Balakrishnan,Tian Lei,Hye Ri Kim,Young Il Song,Young Jin Kim,Kwang S. Kim,Barbaros Özyilmaz,Jong Hyun Ahn,Byung Hee Hong,Sumio Iijima,Sumio Iijima +16 more
TL;DR: The roll-to-roll production and wet-chemical doping of predominantly monolayer 30-inch graphene films grown by chemical vapour deposition onto flexible copper substrates are reported, showing high quality and sheet resistances superior to commercial transparent electrodes such as indium tin oxides.
Journal ArticleDOI
Gold catalysts prepared by coprecipitation for low-temperature oxidation of hydrogen and of carbon monoxide
TL;DR: In this paper, gold catalysts were prepared by coprecipitation from an aqueous solution of HAuCl4 and the nitrates of various transition metals, including Auα-Fe2O3, AuCo3O4, and AuNiO.
Journal ArticleDOI
Water-Assisted Highly Efficient Synthesis of Impurity-Free Single-Walled Carbon Nanotubes
TL;DR: In this article, the authors demonstrate the efficient chemical vapor deposition synthesis of single-walled carbon nanotubes where the activity and lifetime of the catalysts are enhanced by water.
