Researchers Develop Third and Final 'Made

2021/4/9When the hexagons of carbon in the nanotube come together in this honeycomb lattice, they form either an armchair, zigzag or chiral configuration. The name 'zigzag' is used for the configuration in which the 'path' of each molecular bond between carbon atoms is directed first leftward by 60 degrees, then rightward by 60 degrees, then left 60 degrees, then right 60 degrees again: a zigzag pattern.

Activation of carbon controlled oxidation of carbon atoms is done by steam at high temperature, enhances, the internal surface of the carbon to 1000-1200 m2/g. The activation process generates a network of minute openings (pore or cavities) of different diameters on the carbon surface which become the path for water to access the extended internal surface created by the activation.

Efficient Synthesis of Carbon Nanotube–Nanoparticle

2006/10/23A simple and versatile approach has been developed to synthesize different carbon nanotube (CNT)–nanoparticle hybrid materials. The strategy is based on the nondestructive (noncovalent) functionalization of pristine CNTs and the subsequent in situ synthesis of a variety of different nanoparticles, including metal, semiconductor, and insulator particles, on the modified CNTs.
