A simple method has been developed for the preconcentration of benzene and phenolic compounds (BPC) by the adsorption of its carbon nanotubes (CNTs). The preconcentration of benzene and phenolic compounds (BPC) are ubiquitous pollutants, and many of them are carcinogenic or mutagenic. Carbon nanotubes (CNTs) are a kind of novel and interesting carbon material which can be used for separation an...

Interfacial friction plays a crucial role in the mechanical properties of carbon nanotube based fibers, composites, and devices. Here we use molecular dynamics simulation to investigate the pressure effect on the friction within carbon nanotube bundles. It reveals that the intertube frictional force can be increased by a factor of 1.5-4, depending on tube chirality and radius, when all tubes co...

The investigation of renewable and recyclable materials becomes more critical every day due to the high levels waste carbon emissions their impact on environment. use eco-friendly materials, such as natural fibers bioplastics, is increasingly important, always popular. aim this research evaluate changes in properties composite made Poly-Butyl-Succinate (PBS), a biodegradable thermoplastic matri...

semiconducting carbon nanofibers (cnf) are prepared from three different sources, i.e., acetylene, ethanol, and cotton by the chemical vapor deposition (cvd) process. these fibers are having rich elastic, engineering and conductivity properties. fresh self-compacting concrete (scc) flows into place and around obstructions under its own weight to fill the formwork completely and self-compact, wi...
