This paper describes the fabrication and characterization of a hybrid nanostructure comprised of carbon nanotubes (CNTs) grown on graphene layers for supercapacitor applications. The entire nanostructure (CNTs and graphene) was fabricated via atmospheric pressure chemical vapor deposition (APCVD) and designed to minimize self-aggregation of the graphene and CNTs. Growth parameters of the CNTs w...

An important prerequisite to translating the exceptional intrinsic performance of 2D materials such as graphene and transition metal dichalcogenides into useful devices precludes their successful integration within the current 3D technology. This review provides theoretical insight into nontrivial issues arising from interfacing 2D materials with 3D systems including epitaxy and ways to accommo...

Graphite oxide constitutes carbon network with oxygen atoms both on hexagonal arrangement and the edge sites. Structural and electronic properties for graphite-oxygen complexes have been explored using first-principles total-energy calculations within the local density approximation (LDA). Band structures and density of states for the propose carbon 3D models are reported. A finite energy gap and...

This article fundamentally reviews progress in the design and manufacturing of three-dimensional (3D) graphene-based nanocomposites for technical applications. The 3D graphene nanostructures have been manufactured using techniques like template method, chemical vapor deposition, sol-gel, freeze-drying, hydrothermal technique, other approaches. nanofoam has reinforced polymers to achieve superio...

Diodes made of heterostructures the 2D material graphene and conventional 3D materials are reviewed in this manuscript. Several applications high frequency electronics optoelectronics highlighted. In particular, advantages metal-insulator-graphene (MIG) diodes over metal-insulator-metal discussed with respect to relevant figures-of-merit. The MIG concept is extended 1D diodes. experimentally im...

in this research, graphene was synthesized by chemical vapor deposition (cvd) method in atmosphere pressure (14.7 psi). different functionalization method was used for oxidizing of graphene such as acid and alkaline treatments. the functionalized graphene (fg) was characterized by ftir and raman spectroscopy. nanofluid with water and different concentration (0.05, 0.15 and 0.25 wt %) of fg were...

in this study, an efficient and facile technique for preparing graphene oxide in suspension and powder forms was presented based on a modification on hummers' method followed by an additional ultrasonic process. the method involved the provision of graphene oxide from graphite by reaction of potassium permanganate and sulfuric acid with stabilizing the medium complex. furthermore, this stu...
