“…To study mechanical properties at the nano- and micro-scale, a number of nano-/micro-mechanical testing (SSMT—small scale mechanical testing) methods [ 42 , 43 , 44 , 45 ] are employed. Atomic force microscopy (AFM) [ 46 , 47 , 48 , 49 ] and nano-indentometry (NI) [ 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 ] can be named as the most widely used ones.…”

“…They have similar structure flowcharts (see Figure 5 ) and capabilities [ 45 , 50 , 52 ]. In both cases, a high precision driver brings a probe, with the radius of its curve being from a few (in AFM) to a few tens (in NI) of nanometers, close to the studied surface and the probe starts interacting with it.…”

“…To study mechanical properties of wood cells, various SSMT methods are used [ 45 ], and the most widespread ones are AFM [ 89 , 92 ] and NI [ 70 , 71 , 74 , 75 , 93 ]. Let us present some typical examples of NI application with load P max = 0.1–1 mN to this problem.…”

“…In most cases, the value of A that used to be called the Hall-Petch constant turned out to be deformation-dependent [ 139 ]. Later it was clarified that external dimensions affect the mechanical properties in the similar way, though the index of power may differ from 0.5 [ 45 ].…”

This review describes methods and results of studying the mechanical properties of wood at all scales: from nano- to macro-scale. The connection between the mechanical properties of material and its structure at all these levels is explored. It is shown that the existing size effects in the mechanical properties of wood, in a range of the characteristic sizes of the structure of about six orders of magnitude, correspond to the empirical Hall-Petch relation. This “law” was revealed more than 60 years ago in metals and alloys and later in other materials. The nature, as well as the particular type of the size dependences in different classes of materials can vary, but the general trend, “the smaller the stronger”, remains true both for wood and for other cellulose-containing materials. The possible mechanisms of the size effects in wood are being discussed. The correlations between the mechanical and thermophysical properties of wood are described. Several examples are used to demonstrate the possibility to forecast the macromechanical properties of wood by means of contactless thermographic express methods based on measuring temperature diffusivity. The research technique for dendrochronological and dendroclimatological studies by means of the analysis of microhardness and Young’s modulus radial dependences in annual growth rings is described.

“…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.
