in order to evaluate the effectiveness of the iranian made charcoal tubes in the field , 60 local made and 60 imported ones (skc type) were randomly selected and placed side by side for sampling aromatic hydrocarbons (including benzene, toluene, xylene) in workers breathing zone in a paint factory. the results indicated that there were no statistically significant differences between the mean c...

An attempt was taken to study the wear rate of coated Inconel 625 using 0.3 gm multiwall carbon tubes (MWCNT).The coating carried out by Ni-P electroless method. The Ni-P-MWCNT prepared nickel phosphorous solution. sliding test conducted pin on discs tribometer. behavior investigated at various levels tribometer factors, and a predictive model developed regression equations. experiment based L2...

This paper presents the prediction of piezo-resistive behavior under quasi-static uniaxial compression loads using Percolation Excluded Volume (PEV) approach. The PEV approach is supplemented by Finite Element (FE) simulations to calculate displacements Carbon Nano-Tubes (CNTs) embedded in a polymer matrix. number contacts between CNTs determined minimum distance threshold (tunnelling distance)...

In this work at the first step calcium hydroxide nano-particles were synthesized via sono-chemical method at room temperature. At the second step aminated multi-walled carbon nano-tubes was prepared via chemical modification of surfaces of CNT. Finally modified-MWCNT and Ca(OH)2 were added to paraloid matrix by aid of ultrasonic irradiation. Paraloid-modified-MWCNT-Ca(OH)2...

In this work, carbon nanotube (CNT) based interconnections and switches will be reviewed, discussing the possibility to use nanotubes as potential building blocks for signal routing in microwave networks. In particular, theoretical design of coplanar waveguide (CPW), micro‐strip single‐pole‐single‐throw (SPST) and single‐pole‐double‐throw (SPDT) devices has bee...

The first aim of this study was to fabricate vertically aligned multiwalled carbon nanotubes (MWCNTs). MWCNTs were successfully prepared by using plasma enhanced chemical vapour deposition. Further, three carbon composite electrodes with different content of carbon particles with various shapes and sizes were prepared and tested on measuring of nucleic acids. The dependences of adenine peak hei...
