Carbon Rods for Carbon Evaporation in Electron

Carbon Rods and Fibers for carbon rods which are used for carbon evaporation in EM applications, either to coat non-conductive samples with a thin layer of carbon or to produce support films for TEM samples. Rave Scientific 8 Heller Park Lane Somerset, New

Carbon Fibres

The resulting carbon layer has similar properties as a carbon layer evaporated from carbon rods. However, the thickness of the carbon layer depends on the thickness of the carbon fiber threads. Power requirements are approximately 20V/20A (lower than for carbon rods) depending on carbon thread diameter, but can vary depending on brand and type of carbon coater.

Surface

Evaporation of aqueous droplets of carbon nanotubes (CNTs) coated with a physisorbed layer of humic acid (HA) on a partially hydrophilic substrate induces the formation of a film of CNTs. Here, we investigate the role that the global geometry of the substrate surfaces has on the structure of the CNT film. On a flat mica or silica surface, the evaporation of a convex droplet of the CNT

Carbon fiber and thread for carbon evaporation

The carbon fiber braids, when attached properly to the holding posts, will give repeatable carbon coating thickness when the same distance from sample surface to evaporation source is used. The carbon fiber braids are processed to resist unraveling at the ends when cut to length.

Synthesis of carbon nanostructures by arc evaporation

2003/1/1Yields of single-walled carbon nanotubes (SWNTs) produced from electric arc evaporation of graphite electrodes with 3Co/Ni and YNi 2 catalysts differ substantially. For instance, with YNi 2 catalyst, the SWNT yield is ∼30–50 wt.% in 'collar' soot and ∼10–15 wt.% in 'wall' soot, while with 3Co/Ni catalyst, the yields are ∼15–20 wt.% and 2–3 wt.%, respectively.

Carbon Nanotube Network Formation from

Fabrication of single-walled carbon nanotube (SWNT) networks using evaporation of SDS−SWNT sessile drops on a hydrophobized silicon substrate is reported. It is suggested that the organization of nanotubes during evaporation is controlled by aggregates (in the SDS−SWNT dispersion) and hydrophobicity of the substrate. On hydrophobic substrates, the evaporation of SDS−SWNT sessile
