We investigated the production of the graphite contained in the soot of single-walled carbon nanotubes (SWCNTs) synthesized using the arc discharge method with a poorly graphitized carbon (PGC) rod in comparison to a graphite rod. A PGC rod was produced using a mixture of coal tar and carbon black and was heat treated to 1000°C. The rod was packed with a mixture of iron (Fe), nickel (Ni), sulfur (S),...
LaC 2 @CNC/LaB 6 nanocomposites were prepared using a spark plasma sintering system, and their mechanical properties and the intensity of characteristic La X-rays from the composites were characterized for application as X-ray target material. Using LaB 6 as a binder, we succeeded in producing LaC 2 @CNC/LaB 6 nanocomposites with a bulk density (2.91 g/cm ...
Binder-free multi-walled carbon nanotube (MWCNT) blocks from fluorinated MWCNTs were prepared using thermal heating and a compression method in vacuo. The resulting carbon nanotube blocks are lighter than graphite, can be machined and polished, possess average bending strengths of 102.2MPa, a bending modulus of 15.4GPa, and moderate wettability. The binder-free MWCNT blocks possess good biocompatibility...
A soot composed of radial single-walled carbon nanotubes (r-SWCNTs), in which 70nm length nanotubes are grown radially around the core metal particles, and nanohorn-like carbons (NHCs) was used as reinforcement for a styrene–butadiene rubber (SBR). The fracture stress of r-SWCNT soot (38phr)/SBR was 6.3MPa at 60% strain. Furthermore, the hardness value of r-SWCNT soot (38phr)/SBR was 94, which is...
