โœฆ Synopsis

Various surface complexes were adsorbed on coconut-shell steam activated carbons. The surface area changes were studied in conditions where reversion of the surface by exposure to air was not possible. The exposure to other chemical environments was compared to results where atmospheric reversion had taken place. 129. Copper sphere development in carhonked viscose rayon containing CuClz A. Capon, J. M. Creasey and R. A. Cox (Chemical Defence Establishment, Porton Down, Salisbury, Wilts, England). On carbonisation CuCI, treated viscose rayon produces 0.1-1.0 p diameter copper spheres on the fibril surfaces. During activation these spheres penetrate the carbon structure. Investigations by SEM and DTA show that sphere formation is complex, involving initially surface crystallite formation, then decomposition giving copper containing whiskers and finally spheres.

The formation of pentagonal defects and bamboo-like structures in carbon nanotube (NT) growth is viewed within the framework of the surface diffusion (SD) growth model. NT open edge stability is considered as a competition between: (i) hexagon formation which depends on the rate at which C units are

## Abstract The oxidation and carburization of two 20 Cr 30 Ni alloys with nominally 0 and 0.5 wt % Si have been investigated by cyclic exposure to carbon monoxide and carbon dioxide at 1000ยฐC. In carbon monoxide a chromium oxide film is formed which inhibits further carbon deposition. In carbon d

## Abstract The kinetics and mechanism of the oxidation of carbon by NO~2~ in absence and presence of water vapor were studied in a fixed bed reactor. The rate of carbon oxidation by NO~2~ is enhanced in the presence of water vapor in the range of temperature 300โ€“400ยฐC. The benefit effect of water
