RMC and Voronoi diagram methods are applied for analysis of disorder carbon.Quantitative characteristics of the local atomic structure are established.A major portion of the carbon atoms is combined into 3-fold rings.5-fold faces are predominant in the Voronoi polyhedra.Regular configuration polyhedra ...
Fig. 9. a) Schematic diagram displaying the overall evolution of wheat straw into few-layer graphene, b, c) SEM, d) TEM, and e) SAED pattern of few-layer graphene. Adapted from [200] after the required permission. In another study, 2D porous carbon nanosheets derived from silk were syn...
Carbon nanotubes (CNTs), one-dimensional (1D) metastable carbon nanostructures, have attracted significant attention1,2,3,4,5,6 in recent decades due to their unique physical and chemical properties, despite not having accurate positions in the temperature–pressure (T-P) phase diagram of carbon7...
Numerical calculations establish the conductivity diagram as a function of these two parameters, directly linking microstructures to electrical properties. Our work represents an important step towards understanding the structure–property relationship of amorphous materials at the fundamental level and paves ...
The boundaries of the diamond growth domain in the triangular C - H - O gas composition diagram appear to be straight lines. It is shown that this is consistent with a simple model of the competition between the deposition of diamond and amorphous carbon phases. Gas phase carbonaceous ...
A detailed analysis of the atomic and electronic structure in solid-density l-C based on time-resolved x-ray absorption spectroscopy and theoretical simulations is presented. The method can be fruitfully used for extending the experimental investigation of the C phase diagram in a vast unexplored ...

FIG. 2 is a diagram illustrating a structure of a functionalized nanotube (NT) array, according to one embodiment of the invention. FIG. 3 is a flowchart illustrating a process to process functionalized carbon NTs for a specific application according to one embodiment of the invention. FIG....
A schematic diagram of such a cell is presented in Fig. 1(b) [42]. The carbon anode material itself is prepared by dispersing the selected carbon materials along with a binder such as poly(vinylidene fluoride) (PVdF) on a current-collector [42]. The present review concerns the employment...
Schematic diagram of AHD model geometry and its settings: (a) fluid discharges from a pipe through an inlet of radius r0 (red point) with total flow rate Q and temperature Tin. The flow is distributed radially, where it cools by transferring heat to the rock below and above (color-gradien...
