The aim of the first part of this thesis was to optimize the experimental conditions of the chemical synthesis of the crystallographic variety 纬-MnO2, recognised as the most reactive form, in order to study its electrochemical performance as a battery material in the medium KOH 1 M. The ...
The methods are applied to detect inhomogeneities in optical fibres. A theoretical analysis of a few interference images and some experimental results are presented. [Journal translation]P. G. VerlyJohn W. Y. Litcanadian journal of physics
