This collection of papers presents the main results of a logical analysis of
extensive theoretical and experimental searches for efficient ways to overcome two long-standing scientific and technical problems: (1) the creation
of a driver of inertial thermonuclear synthesis with a positive gain of energy
and (2) the neutralization of artificially created radioactive materials accumulated as a product of the human activity.
The collection reports the main achievements of theoretical and
experimental studies performed by a group of experts in a number of relevant
areas: the synthesis of stable dynamical structures of different physical natures; focusing and self-focusing of electron and plasma beams; concentration
and self-concentration of energy in material media and physical structures
on different scales; and the study of both the nuclear combustion mechanism of substances under laboratory conditions and the chemical elements
produced by such a combustion.
