Abstract: An energetic composition with controlled detonation having at least a first organic material and a second material, where the second material is a porous material (micro-, meso-, or macroporous), having a pore ratio of at least 10% and preferably greater than 50%, and the first material is, at least partially, infiltrated into the pores of the second material. A mixture containing such a composition, and a method for manufacturing such a composition and such a mixture. Additionally, a method for fragmenting or expanding a microporous material at nanoscale.

Abstract: Process for polarizing at least a part of a ferroelectric material in a cylindrical shape having a longitudinal axis, and having an internal conductor inside the cylinder disposed along the longitudinal axis. At least part of said cylinder is placed in a conductive liquid with the cylinder being free from any stresses other than pressure exerted by the conductive liquid. A low frequency AC voltage is then applied between an electrode in contact with the conductive liquid and the internal conductor, and the amplitude of the voltage is increased progressively up to a value such that an electrical field is created having an amplitude greater than a coercive field of polarization Ec of the ferroelectric material.
