“…According to this the great scientific and practical interest has the use for track membrane production the method of super deep penetration (SDP) [4]. This method permits to realize complex physical effects such as an intensive electromagnetic radiation, an intensive strain, pressure of 8-20 GPa, "galactic" flows, and so on [5].…”

Membrane separation processes and novel separation science are not immature yet visionary avenues of science. Scientific endeavor in nano-filtration and nanomembranes needs to be readdressed and reenvisioned at each step of human research pursuit. This chapter provides mainly comprehensive overview of the current state-of-the-art polymeric nano-membranes. The main experimental results were carried out by academician Oleg Figovsky and his researchers in IRC Polymate (Israel). Membrane technology is a rapidly growing field having a large economic and ecological consequences and importance. As we all know, track membranes are more effective [1]. Nowadays, nanomembranes constitute an interesting topic in the wider field of nanotechnologies. This chapter provides a comprehensive overview of the current state-of-the-art polymeric nanomembranes. The solution diffusion mechanism of polymeric nanomembranes and the factors contributing to the transport of polymeric nanomembranes are discussed. Mixed-matrix membranes that focus on the development of innovative membranes, comprising of polymer matrix, have become one of the emerging technologies; the concept of these mixed-matrix nanomembranes is discussed. Nanoblends of the polymeric membranes are evaluated with the nano-phase removed for controlled porosity. Nanomembranes are defined as freestanding structures with a thickness in the range of 1-100 nm and an extremely large aspect ratio of at least a few orders of magnitude. To illustrate

“…В основном необычные экспериментальные результаты -глубины динамического массопереноса ≥100 калибров, необъяснимые с точки зрения механических и гидродинамических моделей, скрывают . Например, удалось изготовить стальные толстые плиты с шариками ртути внутри (диаметром в миллиметры) [3] . Длительное время существовала проблема воспроизводимости этих аномальных результатов .…”

“…Характерным дефектом, наблюдаемым при ударе, является каверна-кратер . При прочих равных условиях соударения объем кратера зависит от удельного веса материала преграды, его пластичности и прочности [3] . В выбранном диапазоне режимов воздействия сгустком частиц карбида кремния получены результаты, приведенные в табл .…”

“…Оценка количества энергии, затрачиваемой на изменение геометрии зерен. Поскольку энергия, затрачиваемая на двойникование, изменение геометрии и размеров зерен, составляет порядка 5% от энергии ударной волны, общая энергия, затраченная на эти микроструктурные изменения, составит не менее 5⋅10 3 Дж .…”

Possibilities of creation of composites with application of a method of super-deep penetration (SDP) are considered. At drifting of metals and alloys in a regime of super-deep penetration powdered particles penetrate to depths into tens and hundreds millimetres. Results are brought, that at driving in a metal lower die (in the enclosed system) powdered particles generate additional energy. The filaments (channels) doped by substance introduced by powders and synthesised materials are besides, shaped. It is shown, that doping in regime SDP is localised in reinforcing zones and occurs at the expense of a heading of a material of microparticles and synthesis in high pressure zones.

“…Crushing particles in stages of acceleration and impact about a barrier at 5-10 time was marked. At penetration (motion) into mode SDP hardness of striker material has no significant influence [4]. Flows from particles of oxide of aluminium or lead get into copper on depths in tens millimeters also.…”
