in this paper, the chemical functionalization of carboxylated multi-walled carbon nanotubes (mwnt-cooh) by 1,2-phenylenediamine, have been investigated. mwnt-benzimidazole is obtained through mwnt-amide reaction with pocl3 after 72h, which is confirmed by ft-ir, sem, tga, and elemental analysis. these functionalizations have been chosen due to –nh2 and nhco active sites in mwnt-amide for future...

This paper describes a continuum model for analyzing the inelastic behavior of a single walled carbon nanotube (SWCNT) in different loading conditions. Because of limitations in using molecular dynamics (and other atomic methods) to model the failure load of the SWCNT, continuum mechanics methods are considered in this paper. Based on some experimental and theoretical results, an elasto-plastic...

Very recently, a series of papers dealing with the reduction of organic halides at silver cathodes have appeared. The most important result emerging from such studies is that silver exhibits extraordinary electrocatalytic activities towards the reduction process, especially in the case of bromides and iodides. The possibility of exploiting the electrocatalytic nature of silver in electrocarboxy...

Novel method doped carbon with nanoparticle Cr2O3 and thin film has been studied in much thought in wavelength range, the doping can help new excellent physical and chemical properties for carbon, this application has a semiconductor feature. Nanocomposite thin film deposited on copper and glass substrates have been created by utilizing Spray Pyrolysis method. The prec...

This review paper provides researcherwith a comprehensive information about the Carbon Nano tubes and the catalyst parameters that influences theproduction and morphology of the of Carbon Nano tubes.Carbon nanotubes, referred to as CNTs, are one of the most important materials used in electrical, mechanical, thermal, chemical and textile industries. Since discovery of CNTs in 1991, many scienti...

Abstract Auxetic materials showing a negative Poisson’s ratio can offer unusual sensing capabilities due to drastic percolation changes. This study presents the capacitive response of wet-fractured carbon nanotube paper composites in exposure humidity. A strained composite strip is fractured produce numerous cantilevers consisting cellulose fibers coated with nanotubes. During stretching, thin ...
