A test facility for a plane jet

The initial region of a two-dimensional jet is investigated for the first two slot widths and measurements of the entrainment, using a direct measurement technique, are presented. It is seen that particles reduce the mixing rate.     

Manganese dioxide — a review of a battery chemical Part II. Solid state and electrochemical properties of manganese dioxides

A literature survey indicated that the properties such as electrical conductivity, magnetic susceptibility, thermal decomposition temperature and water content influence the activity of manganese dioxides.Infrared spectroscopy is considered as a convenient analytical tool with which to characterize the various crystal phases of the dioxides. Increasing attention has also been given to predicting the potentials of the system (MnO₂)_1?r. MnOOH_r during electrochemical reduction with a view to understanding the observed discharge characteristics.Further, attempts are being made to correlate the activity of the dioxides with their structural features.
