Carbon nanotubes have unique properties like high stability, high surface to mass ratio and so on which make them suitable for medicinal purpose applications. Treatment of cancer by organoplatinum agents like Cisplatin has become unresponsive in most cases due to low distribution of drug in biological fluids, inability of drug to cross cellular membranes and low stability in biological environm...

Rapid variations of the environmental energy caused by ultrashort laser pulses have induced phase transitions in carbon allotropes, therefore bringing the promise of revealing new carbon phases. Here, by exposing polycrystalline graphite to 25 fs laser pulses at 4 J/cm(2) fluence under standard air atmosphere, we demonstrated the synthesis of translucent micrometer-sized structures carrying dia...

In the present study, the effects of arrangement and distribution of multifarious types of defects on fundamental frequency of carbon nanotubes are investigated with respect to different chirality and boundary conditions. Interatomic interactions between each pair of carbon atoms are modeled using two types of non–linear spring–like elements. To obtain more information about the influences of d...

The examination of variation of elastic modules in single wall carbon nanotubes (SWCNTs) is the aim of this paper. Full nonlinear spring-like elements are employed to simulate specific atomic structures in the commercial code ABAQUS. Carbon atoms are attached to each node as a mass point using atomic mass of carbon atoms. The influence of dimensions such as variation of length, diameter, aspect...

growing process of industrialization in different societies, excessive expansion of industries and factories and increase transport industries, push human toward unstable development. among these problem, massive volume of pollutions is also added to the atmosphere. air pollution in industrial societies and cities is more intensive. global warming is one of the major problems of 21 century. co2...
