Personalized energy systems based on nanostructured materials

Abstract

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.

Insight into tribological and corrosion behaviour of binderless TiCxNy ceramic composites processed via pulsed electric current sintering technique

“…The FCC structure of TiC 50 N 50 is traceable to sodium chloride type with Fm3m space group for TiCN phase, according to the characteristics of each of the phases. The FCC also indicates that carbon atom statistically fills the metal lattice and octahedral interstitial spaces compared to TiC 50 N 50 , which is attributed to space group number Pm3 m. Ti and N atoms occupy the octahedral interstitial site of the volume-centred cubic structures of TiC 70 N 30 and TiC 90 N 10 [36]. The reference unit cell was made up of sintered titanium carbide compact with a purity of 99.8%.…”

“…The electron backscattered diffraction technique (EBSD) was B1 Fm-3m 0.4330 [36,38] employed to identify and understand the crystallographic features of the specimens, and the inverse pole figure maps obtained are presented in Fig. 6.…”
