Films of vertically aligned single-walled carbon nanotubes (SWNTs) with a few μm thickness were grown by catalytic chemical vapor deposition (CVD) on quartz substrates. Low-temperature CVD from ethanol was performed by using densely mono-dispersed Co-Mo catalyst of ≈ 1.0 – 2.0 nm prepared on quartz substrates by a dip-coating method. Continuous reduction of(More)
Bimetallic catalysts (Co:Mo ≈ 2:1 in atomic ratio) were prepared on quartz substrates from metal acetate solutions using a procedure of dip coating, followed by calcination and reduction. High-purity single-walled carbon nanotubes (SWNTs) 1–2 nm in diameter were grown densely (~1.0×10 17 m-2) and vertically on these substrates during an alcohol catalytic(More)
A standardized CPUE analysis of the Japanese distant-water skipjack pole-and-line fishery in the western and central Pacific Ocean (WCPO), 1972-2009. ABSTRACT Since 2000, stock assessments of skipjack tuna in the WCPO have incorporated standardized CPUE indices derived from the analysis of catch and effort data from the Japanese pole-and-line fishery. The(More)
Standardized CPUE for skipjack caught by Japanese offshore pole and line fishery in the northern region of the western and central Pacific Ocean. Summary We attempted to standardize a catch per unit effort (CPUE) for a skipjack tuna caught by Japanese offshore pole and line fishery in the northern region of northwestern Pacific Ocean (northern part of(More)
We have succeeded in direct synthesis of single-walled carbon nanotubes (SWNTs) on a conductive substrate coated with a 3D mesoporous silica film, and observed the field emission. Co catalysts for the growth of SWNTs are deposited on the substrate by electroplating. The particle size of the catalyst is well controlled inside defined space of the mesoporous(More)
The ability to observe chemical reactions at the molecular level convincingly demonstrates the physical and chemical phenomena occurring throughout a reaction mechanism. Videos obtained through in situ transmission electron microscopy (TEM) revealed the oxidation of catalytic soot under practical reaction conditions. Carbon oxidation reactions using Ag/SiO2(More)
Vertically aligned single-walled carbon nanotubes (SWNTs) up to 5 microns thick as shown in Fig 1 were produced by an alcohol CVD process [1]. In contrast to the first report of CVD growth of vertically aligned SWNTs [2], hydrogen gas was supplied only during the heating-up stage with the improved background vacuum condition. A time-progressive(More)
