“…The resulting gel was then dried and subsequently pyrolyzed to convert the organic binder to carbon, yielding the SWNT-CA nanofoam. The volume percent of SWNTs in each sample was calculated from the initial mass of SWNTs added, a CNT density of 1.3 g/cm 3 , and the final volume of the sample. The synthesis process for the SWNT-CA allows for a range of possible shapes and sizes.…”

“…26 The MWCNTs also have high modulus (1 TPa) along their length direction, as well as high bending modulus (0.9-1.24 TPa). 27 Therefore, they have been considered as ideal reinforcing fillers for polymer matrixes to achieve high performance and extensive applications since the discovery of carbon nanotube in 1991 by Iijima. [28][29][30] The most common methods, such as melt-blending and solution-casting, which are developed for making polymer composites with inorganic fillers, are also adopted for making MWCNTs-enhanced polymer composites.…”

A triple‐band multi‐input multi‐output (MIMO) antenna is presented.The proposed antenna consists of a C‐shaped monopole antenna that provides dual‐band resonant antenna. By protruding an L‐shaped parasitic strip on the ground plane, a third band as well as enhancement of the isolation between two ports in MIMO array is achieved. The proposed antenna can cover 2.1–2.6, 3.3–4, and 5.4–6 GHz, which are allocated for WLAN and WiMAX applications. The proposed triple‐band antenna structure is used in different two‐element MIMO arrays. Simulation results show that the S11, S12, and S22 of the MIMO arrays are independent of the position of the two‐element. The results show good S‐parameters, high peak gain and radiation efficiency, and stable radiation patterns among the triple‐band coverage. © 2012 Wiley Periodicals, Inc.

“…The contact force exhibits a strongly nonlinear dependence on displacement and appears fundamentally different from the response of a forest of CNTs [15][16][17][18]. The obtained results in [12] have been compared to the Hertz elastic model [19] of a solid sphere and a planar surface in contact where, if F is the force of contact and is the displacement, F 1:5 [19].…”

Entanglement and the Nonlinear Elastic Behavior of Forests of Coiled Carbon Nanotubes

Helical or coiled nanostructures have been objects of intense experimental and theoretical studies due to their special electronic and mechanical properties. Recently, it was experimentally reported that the dynamical response of a foamlike forest of coiled carbon nanotubes under mechanical impact exhibits a nonlinear, non-Hertzian behavior, with no trace of plastic deformation. The physical origin of this unusual behavior is not yet fully understood. In this Letter, based on analytical models, we show that the entanglement among neighboring coils in the superior part of the forest surface must be taken into account for a full description of the strongly nonlinear behavior of the impact response of a drop ball onto a forest of coiled carbon nanotubes.
