Nanocarbons formed in a hot isostatic pressure apparatus

Wall structure and surface chemistry of hydrothermal carbon nanofibres

“…However, it has been argued that the MWNTs might have a scroll structure [4] or consist of a mixture of scroll-like and concentric structures [5]. In addition to the well-documented cylindrical structure, conical structure of MWNTs has also been reported [6,7]. The graphite layers of conical tube walls lie at a certain angle with respect to the tube axis and terminate at both inner and outer surfaces of the tubes.…”

Novel method of flat cold cathode formation from carbon–nitrogen nanofibers

“…The maximum nitrogen concentration (up to 13%) was obtained by using a method of high isostatic pressure (HIP) growth [10,11]. An elevated gas pressure promotes desirable chemical reactions due to elevation of chemical potential and diffusion coefficients.…”

“…The duration of the experiment was less than 9 minutes. Details concerning the HIP construction can be found in [18]. Electron microscopy analysis was performed by JEM-2010 (TEM) and JSM-7600F (SEM).…”

“…The purity of the obtained DAS activated carbon (which is especially important for water purification) is indicated by the low ash content (4.5 %), which is at the level of activated carbon from coconut shells and 3 times less than in AG-3. The patent for active carbon made of anthracite grade DAS belongs to JSC ENPO Inorganica (RF) [18].…”

“…Having completed the structural synthesis, parametric optimization is carried out [17,18]; it determines the main parameters of process equipment systems. Determination of the parameters of the kinematic module is often associated with the optimization of its structure, in particular, due to the rational placement of adjustment elements in it [19].…”
