The exceptional electronic, thermal, mechanical, and optical characteristics of carbon nanotubes offer significant improvement in diverse applications such as flexible electronics, energy conversion, and thermal management. We present an overview of recent research on the fabrication, characterization and modeling of carbon nanotube (CNT) networks or ensembles for three emerging applications: t...

Using first-principles calculations, we model the chemical vapor deposition (CVD) growth of carbon nanotubes (CNT) on nanoparticles of late-transition (Ni, Pd, Pt) and coinage (Cu, Ag, Au) metals. The process is analyzed in terms of the binding of mono- and diatomic carbon species, their diffusion pathways, and the stability of the growing CNT. We find that the diffusion pathways can be control...

The number of possible applications that interface carbon nanotubes with biological systems is rapidly growing, and with these advances comes a need for characterisation of such interfaces. Molecular simulation is one such approach, and many recent examples exist where simulation has been used to investigate the atomic-scale details of the interface between biomolecules and carbon nanotubes (CN...

Carbon nanotube-In2O3 nanocomposites were synthesized by sol-gel method with the help of ultrasonic radiation. The samples were characterized by X-ray diffractometer, transmission electron microscopy and energy dispersive spectrometer. The UV absorbing properties were detected by the UV spectrophotometer. Photo degradation of methylene blue in aqueous solution was investigated by using CNT/In2O...

Traffic flow sensors are import devices to provide inputs for traffic management applications. This NATRL seed project explores the piezoresistive property of the CNT/cement composite and its feasibility as an embedded stress sensor for to detect traffic flow. The experimental results show that the electrical resistance of the CNT/cement composites changes proportionally to the compressive stre...

In the present study, free vibration behaviors of of carbon nanotube (CNT) and boron nitride nanotube (BNNT) have been investigated via Eringen’s nonlocal continuum theory. Size effect has been considered via nonlocal continuum theory. Nanotubes have become popular in the world of science thanks to their characteristic properties. In this study, free vibrations of Boron Nitride Nanotube (BNNT) ...

Carbon nanotube field-effect transistors (CNFETs) are promising candidates to substitute silicon transistors. Boasting extraordinary electronic properties, CNFETs exhibit characteristics rivaling those of state-of-the-art Si-based metal-oxide-semiconductor field-effect transistors (MOSFETs). However, as any technology that is in development, CNFET fabrication process still have some imperfectio...

An improved analytical model is developed based on an interparticle distance concept, to predict the percolation threshold of conducting polymer composites containing graphite nanoplatelets (GNPs) and carbon nanotubes (CNTs). GNPs are modeled as well-dispersed, disc-shaped cylinders, while CNTs were modeled as either well-dispersed sticks or sphere-shaped CNT agglomerates with a higher CNT conc...

Label-free detections of biomolecules have attracted great attention in a lot of life science fields such as genomics, clinical diagnosis and practical pharmacy. In this article, we reviewed amperometric and potentiometric biosensors based on carbon nanotubes (CNTs). In amperometric detections, CNT-modified electrodes were used as working electrodes to significantly enhance electroactive surfac...

The scaling laws describing the thermal conductivity in random networks of straight conducting nanofibers are derived analytically and verified in numerical simulations. The applicability of the scaling laws to more complex structures of interconnected networks of bundles in carbon nanotube (CNT) films and mats is investigated in mesoscopic simulations. The heat transfer in CNT materials is fou...
