The d_(002), Lc, La of isotropic pitch based graphite fibers (IPGF) are (0.3432), 3.432 and 8.053nm respectively, while for anisotropic pitch based graphite fibers (APGF) they are 0.3391, 25.69 and 53.05nm.
With Z14 pig iron as raw material,medium-frequency furnace as the smelting device,adding 1.1% FeSiMg4Re17 as vermicular agents and 1% FeSi75 as inoculants,through vermicularizing treatment and inoculation in flat bottom ladle,controlling the smelting iron temperature within 1420～1450℃ and finishing the pouring within 10 minutes after the reaction,eligible vermicular graphite cast iron pieces are obtained.
Methods Squid melanin was extracted from ink of Ommastrephes bartrami by high-speed centrifugation. By exposing squid melanin to aqueous solutions of FeCl3,the content of bound Fe(Ⅲ) was 5.6%(W/W) of melanin.
The author introduced a method of clearance of lymph nodes guieded by preoperative percutaneous gastric wall puncture under ultrasonography and injection with china ink. 27 cases of gastric cancer received the method.
The carbon-abundant area is the zone where graphite and organic fibre are comparatively gathered, while the spalling area is the zone where the surface film is spalled and its surface is rough and uneven, with a loose and denuded state.
An inverse method is presented to determine the elastic constants of an experimental sample, a titanium graphite unidirectional fiber-reinforced composite plate, using wavelet transform and neural networks.
There exist two novel high-coverage stable structures of potassium adsorbed on SWCNTs, which are not stable on graphite.
Micro-structure of graphite-intercalated tin oxide and its influence on SnO2-based gas sensors
A nano-scaled graphite oxide (GO) was prepared with a micro-layer structure for intercalation.
