In this study, the oxidation of dye from colored wastewater by H2O2/ MWCNT’s multi walls carbon nano tubes solution assisted with UV radiation was investigated. Disperse Blue 56 DB 56 was used as a model dye. Adsorption behavior of DB56 from aqueous solution onto MWCNT’s was investigated under various conditions such as initial pH value, dye concentration, H2O2 and MWCNT’s dosage. Maximum adsor...

We investigate a new generation of fullerene nano-oscillators: a single-walled carbon nanotube with one buckyball inside with an operating frequency in the tens-of-gigahertz range. A quantitative characterization of energy dissipation channels in the peapod pair has been performed via molecular dynamics simulation. Edge effects are found to be the dominant cause of dynamic friction in the carbo...

Background: Biotic and abiotic elicitors produce secondary metabolites and alter physiological traits of the plants by affecting some of the mechanisms within the plant cells. Objective: This study was aimed to investigate the effects of different concentrations of spherical nano-carbon and salicylic acid on physiological traits and paratolenolidae content in Feverfew. Methods: This research ...

Bundles of single-wall carbon nanotubes (SWCNTs) coalesce forming multiwall carbon nanotubes (MWCNTs), containing from two to six nested tubes, under thermal treatment at high temperatures [(2200-2400) degrees C]. This structural transformation is confirmed by extensive molecular dynamics (MD) simulations. The simulations suggest a "patching-and-tearing" mechanism for the single-wall-to-multiwa...

Effective elastic properties for carbon nanotube reinforced composites are obtained through a variety of micromechanics techniques. An embedded carbon nanotube  in  a  polymer  matrix  and  its surrounding  interphase  is  replaced with an equivalent fiber for  predicting  the  mechanical  properties of  the  carbon  nanotube/polymer composite. The effects of an interphase layer between the nan...

effect of nano titanium oxide, nano zinc and multiwall carbon nano tube on yield and yield components of green gram was carried out in kohkiloyeh-boyrahmad province, iran with 30 degrees 45' n and 50 degrees 44' in 2013 growing seasons. the experiment was arranged as factorial in a completely randomize block design with three replications, treatments including: four concentrations (ze...

Pressure sensors are required in all walks of life, irrespective of civilian, defense, aerospace, biomedical, automobile, Oceanography or domestic applications. Naturally, rapid progress has been made in micromachined pressure sensors and the microsystems using these sensors. Starting with metal strain gauges and moving forward with silicon based pressure sensors with flat diaphragms, the searc...
