Application of multilayer carbon nanotubes for creation of coatings absorbing electromagnetic radiation
The article presents the use of carbon nanotubes as modifiers-materials for protection against electromagnetic radiation. The technique of obtaining nanomodified composites, as well as the method of characterization of carbon nanostructures is presented. Studies have shown that there is a linear dependence of the reflection coefficient on the frequency for composites modified multilayer carbon nanotubes based on Ni/0.16 MgO catalyst. It was found that composites containing multilayer carbon nanotubes based on Ni/0.16 MgO allow to achieve low values of the reflection coefficient and non-dependence of the reflection coefficient on the increase in frequency. © Published under licence by IOP Publishing Ltd
Prospects for the use of electric heaters with self-installing thermal contact based on nano-modified materials for aerospace engineering
The article presents the study of heat generation in the heating element, revealed the working temperature and the nature of the distribution of the temperature field. A method of experimental research has been developed that allows one to determine the thermophysical parameters and the distribution of the temperature field on the surface of the materials under study. It is established that the phase transition temperature is shifted by 2 ° C, and the measured thermal conductivity increased for modified heptadecane to a value of 0.3 W / m ° C. It was revealed that the use of a material with a phase transition provides the effect of a self-adjusting thermal contact. Improvement of thermal contact occurs within 20 seconds due to a phase transition in nano-modified heptadecane with its volume increasing by 2%. © Published under licence by IOP Publishing Ltd

The FinTech Industry: Crowdfunding in Context
International audienceThis chapter presents how the financial services sector, especially banking, was a driver for ICT development in the last quarter of the twentieth century and early years of this century. But several phenomena happened on technological, social, and financial fronts in the second half of the last decade that led banks to `get their eyes off the ball' and open the window for a whole new industrial sector to emerge, FinTech. This chapter analyses the phenomenon with the objective of answering: Why did FinTech emerge as an industrial sector, independent of banking? How is the FinTech industry organized and where does crowdfunding fit in? The chapter identifies three external forces that acted upon the banking system and created the conditions for the FinTech sector to emerge. It also looks at the FinTech sector from an industrial organization perspective and proposes a framework connecting financial services functionality and technological applications. © The Editor(s) (if applicable) and The Author(s) 2020
