On the Physics of Catalytic Phenomena

In the first part of the present article, we shall preface the analysis of the conditions of catalyst formation with a review of data on their structure. Using the approach we employ in practical work, we shall differentiate the structural aspects of catalysts and consider each of them separately. I…

Effective Cross Section of Gas Molecules with Respect to Slow Electrons and Ions*

This article deals with the effective cross section (ECS) of molecules with respect to slow electrons and ions. It is, of course, not possible to draw a sharp boundary between “slow” and “fast” electrons and ions. Nevertheless, the history of development, experimental technique, and the nature of th…
