An off-lattice Monte-Carlo simulation was used to study non-isotropic heat conduction in aligned carbon nanotube (CNT)-polymer nanocomposites (PNCs) focusing on the effects of CNT-CNT contact and CNT distribution on heat transfer. CNT-CNT contact significantly affects the effective transport properties of PNCs, including anisotropy ratios, but has not been studied extensively either theoretical...
In recent years, the use of supercritical fluids (SCFs) for the synthesis and processing of nanomaterials has proven to be a rapid, direct, and clean approach to develop nanomaterials and nanocomposites. The application of supercritical fluid technology can result in products (and processes) that are cleaner, less expensive, and of higher quality than those that are produced using conventional ...
With the increased use of composites for load-carrying structures, the ability to obtain strain and damage information is critical to maintain reliable structures in the field. A promising class of multifunctional composites with the ability to self-sense strain and/or damage is possible through the use of carbon fibers and carbon nanotubes. This paper presents a comparative study of two sensor...
This paper proposes the carbon nano structures particularly Carbon nanotube (CNT), Graphene Nanoribbon (GNR), with excellent electrical, thermal and mechanical properties making them an emerging alternative for future onchip interconnect applications. Analysis of CNT and GNR as onchip interconnect has been performed with the help of existing equivalent circuit model. Performance metrics such as...
Using a tight-binding model and a tranfer-matrix technique, we numerically investigate the effects of the coupling strength, and the length of the molecule on the electronic transmission through a CNT/(single) molecule/CNT system. With trans-polyacetylene (trans-PA) as the molecule sandwiched between two semi-infinite carbon nanotube(CNT), we rely on Landauer formalism as the basis for studyi...
Carbon nanotube (CNT)-based electrodes in flexible supercapacitors have received significant attention recent years. fiber fabrics (CNT-FF) emerged as promising materials due to their high surface area, excellent conductivity, and mechanical strength. Researchers attempted improve the energy density rate performance of CNT-FF supercapacitor through various strategies, such functionalization wit...
Here, we report the label-free, sensitive, and real-time electrical detection of whole viruses using carbon nanotube thin film (CNT-TF) field effect devices. Selective detection of approximately 550 model viruses, M13-bacteriophage, is demonstrated using a simple two-terminal (no gate electrode) configuration. Chemical gating through specific antibody-virus binding on CNT surface is proposed to...
Broader applications of carbon nanotubes to real-world problems have largely gone unfulfilled because of difficult material synthesis and laborious processing. We report high-performance multifunctional carbon nanotube (CNT) fibers that combine the specific strength, stiffness, and thermal conductivity of carbon fibers with the specific electrical conductivity of metals. These fibers consist of...
To explain the fast kinetics of H in porous carbon, we propose that the migration relies on H hopping from a carbon nanotube (CNT) to another. Using density functional theory, we have found that the barrier for H hopping becomes smaller than that for diffusion along a tube for certain CNT separations, decreasing to less than 0.5 eV for separations of 3.1 Å. Such significant reduction occurs irr...
