was identifed by SAXS patterns. As shown in Fig. 3, 3 characteristic diffraction peaks associated with the 100, 110, and Fig. 2. Nitrogen adsorption-desorption isotherms (a), and pore size distributions (b) of the fabricated nitrogen-doped ordered mesoporous carbon (NOMC) materials. Fig. 3. Small-angle X-ray scattering patterns of the fabricated nitrogen- doped ordered mesoporous carbon (NOMC)... This paper introduces a nitrogen-doped ordered mesoporous carbon (NOMC) derived from glucosamine with hybrid capacitive behaviors, achieved by successfully combining electrical double-layer capacitance with pseudo-capacitance behaviors. The nitrogen doping content of the fabricated NOMC reached 7.4 at% while its specific surface area (SBET) and total pore volume reached 778 m2 g?1 and 1.17 cm3 g?1, respectively. A dual mesoporous structure with small mesopores centered at 3.6 nm and large... -

proportions of the mi- crostructural features and to quantify the degree of VGCNF dis- persion. The JEOL JSM-6500F feld emission-SEM model was used to image the microstructural characteristics/distributions of the fve material confgurations of interest. Special sample preparation steps, such as the sputter-coating of the sample with gold or palladium and drawing a vacuum around the sample,... -

The range of the C-coated graphite particle size distributions increased with increasing MP concentration, as demonstrated by the following increasing average particle sizes: 58.90, 66.90, 66.90, and 86.40 μm for C0.5G, C1.0G, C2.0G, and C3.0G, re-... Carbon foams (CFms) are of crucial importance in electrical and mechanical devices due to their high thermal conductivity used for eliminating high heat flow and maintaining low temperatures [1]. The most common CFms are types of aluminum alloys, copper and diamond. However, the mechanical properties of metal-based heat sink materials are difficult to control at temperatures over 550°C [2,3]. Thus, CFms are actively investigated as heat sink materials because of their good properties, such as... -

2/g). The pore size distributions for both DWCNT and SWCNT samples were obtained from N2 adsorption isotherms using the density functional theory method, as shown in Fig. 5b. From this fgure, the samples exhibit similar micro- and mesopore distributions. The clearly observed small micropores (ca. 0.8 nm) and the three times larger micropore volume in the DWCNTs are ascribed to well-developed... Double walled carbon nanotubes (DWCNTs) are considered an ideal model for studying the coupling interactions between different concentric shells in multi-walled CNTs. Due to their intrinsic coaxial structures they are mechanically, thermally, and structurally more stable than single walled CNTs. Geometrically, owing to the buffer-like function of the outer tubes in DWCNTs, the inner tubes exhibit exciting transport and optical properties that lend them promise in the fabrication of field-effect...
