Using density functional theory calculations, we show that recently synthesized carbon nanocomposites of graphene nanoribbons encapsulated in a carbon nanotube (GNR@CNT) possess rich emergent electronic and magnetic properties that offer new functionality and tunability and display systematic trends that are sensitive to the matchup of constitutive GNRs and CNTs. The encapsulation of H-passivat...

The excellent mechanical properties of carbon nanotubes (CNTS) are driving research into the creation of new strong, tough nanocomposite systems. Here, the first evidence of toughening mechanisms operating in carbon-nanotube-reinforced ceramic composites is presented. A highly ordered array of parallel multiwall CNTs in an alumina matrix was fabricated. Nanoindentation introduced controlled cra...

Weathering processes can influence the surface properties of composites with incorporated nanoparticles. These changes may affect the release behavior of nanoparticles when an abrasion process is applied. Therefore, the influence of two different weathering processes, immersion in water and exposure to UV light, on the properties of abraded particles from a carbon nanotube (CNT)/epoxy nanocompo...

Photocatalysis is a green technology which transforms available photon energy into useful chemical energy. The reaction mechanism based on the ability to create electron–hole pairs under appropriate light. Semiconductors have attracted great attention in photocatalysts because of their high photosensitivity. Spinel–type cobalt oxide nanorods been prepared by simple hydrothermal method using nit...

the efficiency and robustness of reliability methods are two important factors in first order reliability method (form). the conjugate choice control (ccc) and directional chaos control method (dcc) were developed to improve the robustness and efficiency of form formula using the stability transformation method. in this paper, the ccc and dcc methods are applied for reliability analysis of a co...

Mesoscopic tubular potential is developed for the description of the van der Waals interaction between straight single-walled carbon nanotubes (CNTs) of arbitrary length and orientation. The potential is formulated within a general continuum description of the van der Waals intertube interactions based on the integration of an interatomic potential over the surfaces of the interacting nanotubes...

In this work, novel CNTs/CoSi/SiOC nanocomposite ceramics with in-situ formed multi-walled carbon nanotubes (CNTs) and core-shell structured CoSi@C nanoparticles were successfully prepared via a single-source-precursor derived ceramic approach. The polymeric precursor characterization as well phase evolution, microstructure electromagnetic wave (EMW) absorption properties of t...

Carbon nano-tube (CNT) reinforced metal matrix nano-composites have attracted a great deal of attention in recent years due to the outstanding physical and mechanical properties of CNTs. However, utilizing CNT as reinforcement for alloy matrixes has not been studies systematically and is still a challenging issue. In the present study, Cu80Fe20/10CNT nanocomposite was synthesized by mechanical ...

Poly(3-hydroxybutyrate) (PHB) is a natural, linear, thermoplastic polyester synthesized by microorganisms as intracellular carbon reserves and ion sinks in response to limited nutrient availability and imposed stress conditions. The PHB has become one of the most interesting biomaterials for application in tissue engineering due to its excellent biodegradability and biocompatibility. Nanocompos...

this article deals with the buckling analysis of perfectly bonded cross-ply laminated composite plates reinforced by wavy carbon nanotubes (cnts) under in-plane loads using element free galerkin (efg) method based on first-order shear deformation theory (fsdt). the wavy single-walled cnts and poly-co-vinylene are used for the fibers and the matrix, respectively. the cnt fibers are distributed i...
