Carbon nanotubes (CNTs) coated with titanium oxide (TiO2) have generated considerable interest over the last decade and become a promising nanomaterial for a wide range of energy applications. The efficient use of the outstanding electrical properties of this nanostructure relies heavily on the quality of the interface and the thickness and morphology of the TiO2 layer. However, complete surfac...

The size and parameter optimization for the 5-nm carbon nanotube field effect transistor (CNFET) static random access memory (SRAM) cell was presented in Part I of this article. Based on that work, we propose a (CNT) SRAM array composed schematically optimized CNFET CNT interconnects. We consider interconnects inside metallic single-wall (M-SWCNT) bundles to represent metal layers 0 1 (M0 M1). ...

In this study, multiwall carbon nanotubes (MWCNTs) and double-wall (DWCNTs) have been dispersed in polylactide (PLA) polyamide 11 (PA11) using an internal mixer. Rheological characterization confirmed the formation of nanotube (CNT) networks PLA PA11 attributed to well-dispersed CNTs respective matrices. A lower rheological percolation threshold PLA/MWCNT nanocomposites (less than 0.5 wt. %) co...

Carbon nanotube (CNT) and graphene-based sponges and aerogels have an isotropic porous structure and their mechanical strength and stability are relatively lower. Here, we present a junction-welding approach to fabricate porous CNT solids in which all CNTs are coated and welded in situ by an amorphous carbon layer, forming an integral three-dimensional scaffold with fixed joints. The resulting ...

Abstract Highly dense yttria-stabilized zirconia (YSZ) nano-ceramics reinforced with TC-CVD-synthesized multiwall carbon nanotubes (MWCNTs) were fabricated using spark plasma sintering at a temperature of 1350°C, the heating rate 100 °C/min and pressure 50MPa dwell time 10 minutes.

The focus of present research is the establishment a practical procedure for effective incorporation multi-walled carbon nanotubes (MWCNTs) into alkali-activated materials (AAMs) with aim mechanical reinforcement. Investigated composite in this work was an matrix composed fly ash (FA) and ground-granulated blast furnace-slag (GGBS) as solid aluminium-calcium-silicate precursors along highly con...

In the early 1990s, Iijima (1991) discovered a onedimensional (1D) nanostructure, the carbon nanotube (CNT), which sparked an entirely new avenue within nanoscience and nanotechnology. Nanowires (NWs) (Cui and Lieber 2001), nanorods (Li and Alivisatos 2003), nanotubes (Wang and Li 2003), and nanobelts (Pan et al. 2001) of various materials have been successfully synthesized shortly afterwards. ...

Carbon nanotube sheets have great potential for specific engineering applications owing to their unique, tunable properties such as conductivity. To date, most CNT sheet materials (e.g., buckypapers) are fabricated by using single wall carbon nanotubes (SWNTs). However, multi-wall carbon nanotubes (MWNTs) are much cheaper than SWNTs, and better suited to large scale industrial applications. One...

OBJECTIVES The application of multiwall carbon nanotubes (MWCNTs) currently extends to various fields. However, it has been reported that exposure to CNT causes hazardous effects on animals and cells. The purpose of this study was to quantify the exposure to MWCNT in MWCNT/polymer composites for exposure assessment. We focused on catalytic metals included in the MWCNT and the diameter of dust r...

The catalytic chemical vapour deposition (c-CVD) technique was applied in the synthesis of vertically aligned arrays of nitrogen-doped carbon nanotubes (N-CNTs). A mixture of toluene (main carbon source), pyrazine (1,4-diazine, nitrogen source) and ferrocene (catalyst precursor) was used as the injection feedstock. To optimize conditions for growing the most dense and aligned N-CNT arrays, we i...
