✦ Synopsis

An algorithm proposed by Chen (Combust. Sci. Technol. 57, 89 (1988)) for the construction of reduced chemical kinetic mechanisms is reviewed. It is shown that the algorithm can be formally used only with the steady state approximation. A new algorithm is presented which can accept more general assumptions. However, for the new

algorithm to be successful these assumptions must meet a certain condition which is presented. The reduced mechanisms generated by both algorithms do not provide optimum accuracy and stability in numerical simulations. This can be achieved by a specific refinement of these reduced mechanisms according to the CSP (1a)

method.

## Abstract Nanotubes can be characterized by a very high point symmetry, comparable or even larger than the one of the most symmetric crystalline systems (cubic, 48 point symmetry operators). For example, __N__ = 2__n__ rototranslation symmetry operators connect the atoms of the (__n__,0) nanotube
