Introduction and Preliminaries, of least activity has at times exercised an almost mystical fascination, as if it were the counterpart in natural philosophy of the dictum of Ockham in metaphysical. In mathematics the calculus of variations has a place as a discipline in itself with applications in the proving of existence theorem

Diffusion Limited Reactions,e of a reactant particle. When all reaction processes at the surface of the reactant particle are so fast that surface equilibrium conditions are maintained, the effective (or net) reaction rate does not depend on the nature of the process at the site of reaction, but rather upon the rate of transpo

MODELING POROSITY DEVELOPMENT DURING KOH ACTIVATION OF COAL AND PITCH-DERIVED CARBONS FOR ELECTROCHExcess of KOH. The effects related to parent material nature, KOH/precursor ratio and reaction temperature and time on the porosity characteristics and surface chemistry is described. The results are discussed in terms of suitability of produced carbons as an electrode material in electric double-layer capacitors.
