Journal ArticleDOI
Large-scale synthesis of single-wall carbon nanotubes by catalytic chemical vapor deposition (CCVD) method
Jean-François Colomer,C Stephan,S Lefrant,G. Van Tendeloo,Isabelle Willems,Zoltán Kónya,António M. Fonseca,Ch. Laurent,Janos B. Nagy +8 more
TL;DR: In this paper, a large-scale production of single-wall carbon nanotubes (SWNTs) is reported, where large quantities of SWNTs can be synthesized by catalytic decomposition of methane over well-dispersed metal particles supported on MgO at 1000°C.
Journal ArticleDOI
Production of short carbon nanotubes with open tips by ball milling
TL;DR: In this paper, the average length of the ball milled carbon nanotubes, synthesised by decomposition of acetylene on different types of supported metal catalysts, is ca. 0.8 μm.
Journal ArticleDOI
Green synthesis of gold nanoparticles by thermophilic filamentous fungi
Zsófia Molnár,Viktória Bódai,George Szakacs,Balázs Erdélyi,Zsolt Fogarassy,György Sáfrán,Tamás Varga,Zoltán Kónya,Eszter Tóth-Szeles,Rózsa Szűcs,István Lagzi +10 more
TL;DR: Three different approaches for the synthesis of gold nanoparticles using either the extracellular fraction, the autolysate of the fungi or the intracellular fraction of 29 thermophilic fungi are shown and the formation of nanoparticles with different sizes and size distributions are observed.
Journal ArticleDOI
Control of the outer diameter of thin carbon nanotubes synthesized by catalytic decomposition of hydrocarbons
I. Willems,Zoltán Kónya,Jean-François Colomer,G. Van Tendeloo,N. Nagaraju,Antonio Fonseca,Janos B. Nagy +6 more
TL;DR: In this paper, the outer diameter distribution of the carbon nanotubes was characterized by both low and high resolution TEM and it was shown that the inner diameter can be controlled by choosing the appropriate catalyst.
Journal ArticleDOI
Preparation and characterization of carbon nanotube reinforced silicon nitride composites
TL;DR: In this paper, the hot isostatic press (HIP)-sintering method was used for composite processing of MWNT-silicon nitride composites, which showed a considerable improvement compared to matrices with added carbon fiber, carbon black or graphite.
