Tissue engineering is an innovative interdisciplinary field in which bioengineers and life scientists try to regenerate and reproduce natural tissues through the use of biodegradable structures, called scaffolds, with the aim of mimicking the specific tissue extracellular matrix (ECM). Carbon nanotubes (CNTs) offer a natural platform for obtaining composite microfabricated scaffolds thanks to t...

Advanced composites, such as those used in aerospace applications, employ a high volume fraction of aligned stiff fibers embedded in high-performance polymers. Unlike advanced composites, polymer nanocomposites (...

Graphene, graphene-based nanomaterials (GBNs), and carbon nanotubes (CNTs) are being investigated as potential substrates for the growth of neural cells. However, in most in vitro studies, the cells were seeded on these materials coated with various proteins implying that the observed effects on the cells could not solely be attributed to the GBN and CNT properties. Here, we studied the biocomp...

BACKGROUND Carbon nanotubes (CNTs) have found wide success in circuitry, photovoltaics, and other applications. In contrast, several hurdles exist in using CNTs towards applications in drug delivery. Raw, non-modified CNTs are widely known for their toxicity. As such, many have attempted to reduce CNT toxicity for intravenous drug delivery purposes by post-process surface modification. Alternat...

Carbon nanotubes (CNTs) are generally considered as a promising particle reinforcement of incorporating advanced properties and characteristics into epoxy nanocomposites. This paper investigated the bonding performances CNT-reinforced adhesively bonded joints on steel substrates using single lap shear (SLS) tests. The (including strength, fracture strain, toughness, failure mode) were studied w...

Microwave absorbing property of composites containing Ag nanoparticles filled multiwalled carbon nanotube buckypaper (Ag-BP) has been investigated. Buckypaper doped with silver was prepared by direct dispersion and filtration method. From the low temperature resistivity measurement it was found that increasing doping level decreases the electrical conductivity of the buckypaper. 30 wt. % and 40...

This article presents the forced vibration of composite beams reinforced by single-walled carbon nanotubes (SWCNTs) and subjected to a moving mass. Considering distribution such as uniform (UD-CNT), functionally graded Λ (FGΛ-CNT) X (FGX-CNT), three different are studied. Based on third-order shear deformation theory (TSDT), motion equations derived using Hamilton's principle. Including mass in...

Carbon nanotubes (CNT) are attractive next generation materials due to their unique properties, which lead to high mechanical, electrical, and thermal performance (Iijima, 1991; Endo et al., 1976; Niyogi et al., 2002; Komarov & Mirnov, 2004). This unique nano order material can not only be utilized on its own in precision industrial fields but can also provide high performance functionality in ...

The electrical properties of metallic carbon nanotubes (CNT) can rival, or even exceed, the best metals known. It is a potential candidate for future on-chip interconnect, whose performance will be dominant in the next generation integrated circuits. In this paper, a study on the modeling and simulation techniques for the CNT interconnect network is carried out. The frequency-independent models...

Creating new construction materials with improved strength, elasticity, and durability properties represent the focus of many research works. Significant effort has been invested in investigating use carbon nanotubes (CNTs) cementitious materials, especially multi-walled (MWCNTs) which consist a series concentric graphite tubes. The MWCNTs is closely related to surfactants ultra-sonication proc...
