Development of scaffolds consisting of micro-/nano-sized materials have attracted a great deal of attention for their potential use in tissue engineering tools. We prepared a cell culture scaffold of carbon nanotubes, which is a typical bio-inert nanomaterial, and then investigated the surface morphology and properties. A three-dimensional nano-level network structure was observed using a scann...

The improvement of electrical conductivity of carbon-fiber reinforced plastics (CFRP) has been investigated by conductive silver nano-particles coating for the purpose of aircraft lightning protection. Silver nano-particles in colloid were sprayed on the surface of carbon fibers, which were then impregnated by epoxy resin to form a CFRP specimen. Electrical resistance was measured by contact re...

The preparation of novel NIR fluorescent carbon based nanomaterials, consisting of boron difluoride azadipyrromethene fluorophores covalently attached to carbon nano-onions, is demonstrated. In addition, the analysis of the new nanomaterial is presented. The fluorescent nano-derivative properties are customized such that their emission can be reversibly on/off modulated in response to pH, which...

OBJECTIVES Recent studies have shown that nano-sized carbon black is more toxic than large respirable carbon black because of its higher surface area. However, it is not clear if carbon black made larger by agglomeration demonstrates decreased toxicity. The purpose of this study was to verify if agglomeration affects the toxicity of carbon black using three differently prepared nano-sized carbo...

Interests on carbon nanostructures are growing over the decades since the discovery of buckminsterfullerene and carbon nanotubes (CNTs). The chemical vapor deposition method is promising for nano-carbon synthesis, because it is capable of controlling the carbon structure and achieving high yield. The fine-tuning of different carbon structures is normally focused on varying catalyst compositions...

Terahertz (THz) electromagnetic wave has been widely used as a spectroscopic probe to detect the collective vibrational mode in vast molecular systems and investigate dielectric properties of various materials. Recent technological advances in generating intense THz radiation and the emergence of THz plasmonics operating with nanoscale structures have opened up new pathways toward THz applicati...

The micro and nano-structured amorphous carbon as p-type films prepared from natural palm oil precursor for heterojunction solar cell were presented. Field-emission scanning electron microscopy (FESEM) revealed the micro and nano structured films had particle size in the range of 382 nm to 689 nm and 28 to 34 nm, respectively. The energy-dispersive spectroscopy (EDS) showed the existing of carb...

In this work, the microwave surface wave plasma (MWSWP) equipment is used to grow the carbon nano-materials at low temperature on different catalysts prepared by the so-called plasma assisted sol-gel synthesis method. Without any additional heating method, the plasma itself can heat up the substrate to about 280oC. By applying the -600V bias voltage, the substrate temperature can reach more tha...

carbon nanotubes (cnts) are specific structures with valuable characteristics. in general, the structure of each nanotube is defined by a unique chiral vector. in this paper, different structures of short single-walled cnts are simulated and their mechanical properties are determined using finite element method. for this aim, a simple algorithm is presented which is able to model the geometry o...
