“…As follows from the results of a number of studies on the formation of nanomaterials, in many cases their functional properties are determined by the chemical and thermal prehistory of the initial compositions and the mechanism of their formation [176,177,182,186,189,190,194,198,199,228,352,353]. It is also shown that solid-phase reactions are, in a certain sense, liquid-phase, since reactions in a solid system are activated with the transition of two-dimensional non-atomic phases (intergrain formations) to a liquid-like state, when the reaction rate increases sharply [216][217][218][219][220][221].…”

In this paper, the achievements, problems and prospects of creating personalized energy systems based on nanostructured materials are analysed. Various concepts of developing methods and ways of personalized energy provision for autonomous human survival in remote natural habitat, emergency situations of natural disasters and technogenic catastrophes when centralized power supply is unavailable or in an effort to reduce the economic and environmental costs of remote energy production and transportation are also considered. The possibilities and limitations of using traditional and renewable alternative energy sources, processes and devices for extracting, storing and converting their energy into the necessary consumer forms due to fundamental physical laws are discussed as well. The article covers the new nanostructured materials with special functional properties for personalized energy systems development. The mechanisms for formation of the required nanostructures in synthesized materials, especially those with a high content of fractal interfacial formations, are considered as well as methods for studying their structural and phase characteristics that determine the achievability of the specified parameters of model converters and energy storage devices.

“…Согласно [13,16], образовавшиеся при близких условиях синтеза малые железосодержащие кластеры могут быть локализованы в закрытых порах, на границах зерен, а также на поверхности нанокристаллов. В работах [13, 16,24] среди возможных механизмов, лежащих в основе сильного увеличения намагниченности подобных материалов, указывают присущее наночастицам влияние поверхности.…”

“…Метод растворного горения является эффективным для получения нанокристаллических ферритов различного состава, в том числе Bi 2 Fe 4 O 9 , при достаточно высокой температуре, поскольку быстрое протекание реакции горения не способствует рекристаллизационному росту частиц [11][12][13][14][15][16][17][18][19][20][21][22].…”

“…This can be realized through chemical substitution, [10][11][12][13][14][15][16][17] inducing strain in thin lms, [18][19][20][21] high magnetic elds, [22][23][24][25][26][27] hydrostatic pressure [28][29][30] and nite size effects. [31][32][33][34][35][36] Of these, aliovalent doping controls the chemistry of the material and oen could result in increased chemical pressure that would work similar to applying hydrostatic pressure externally. To this end, we have synthesized Ba-, Ca-and Ba/Ca co-doped samples.…”
