ISSUES OF ENSURING ECONOMIC AND ENERGY SECURITY IN THE “SMART CITY” SYSTEM

The publication reflects the results of research on economic security issues at the level of administrative center of the subject of the Russian Federation in the context of the development of the “smart city” system. Cutting-edge technologies are becoming a powerful engine of transformation, including the energy sector. Development of smart cities and digitalization of services require reorganization of the energy business, search of new innovative opportunities and the development of new strategies, the final result of which will be the creation of new business models for energy suppliers. As a result of largescale statistics and practical cases analysis the main (specific) smart risks, smart challenges and smart threats for the economic security system of the largest city have been classified, recommendations to modify existing business models for Russian energetic industry have been offered

Приведены особенности авторской методики расчета, выгодно отличающие ее от подобного рода разработок. Представлены результаты расчетов и проведено их обсуждение

Highly selective binding of methyl orange dye by cationic water-soluble pillar[5]arenes

© 2016 The Royal Society of Chemistry.A new water-soluble pillar[5]arene with an amide fragment and triethylammonium groups was synthesized by our original method of aminolysis of the ester groups. Using UV-spectroscopy, it is shown that cationic pillar[5]arenes are able to selectively form 1:1 complexes with some hydrophobic anions: the guests with bulky uncharged or negatively charged substituents hindering entry into the macrocycle cavity. Highly selective binding of the most lipophilic guest, methyl orange dye, in the form of organic anion salts by positively charged water-soluble pillar[5]arenes was detected. In the case of the azo dye the appropriate Kass values were 10-100-fold higher than those calculated for the other sulfonic acid derivatives studied. The 2D NMR NOESY 1H-1H spectroscopy confirms the formation of the inclusion complex: negative charge sulfonate head is outside the cavity of pillar[5]arenes and the hydrophobic fragment of the guest is located in the cavity

Improving of the heat supply energy efficiency in Russian cities through the individual heat points introduction

This article states the problems with the use of central heating stations, as well as the need to introduce individual heat points. As a result, the authors considered the issue of improving the energy efficiency of heat supply systems in Russian cities while replacing central heating stations with individual heat points. The beneficial effects of the activities are especially noted

Silica nanoparticles with dual visible–NIR luminescence affected by silica confinement of Tb(III) and Yb(III) complexes for cellular imaging application

© 2019, Springer Science+Business Media, LLC, part of Springer Nature. The work introduces silica confinement of Tb(III) and Yb(III) complexes with p-sulfonatothiacalix[4]arene (TCAS) arisen from their doping into silica nanoparticles (51–60 nm) as the reason for efficient dual green–NIR luminescence. pH-regulated water solubility of the lanthanide complexes is highlighted as prerequisite for the balance between efficient doping of the complexes into silica nanoparticles and their size/shape university. The impact of Tb(III) → Yb(III) energy transfer on the NIR and visible luminescence of the nanoparticles was revealed from photophysical studies of the nanoparticles doped with different couples of lanthanide complexes (Tb–Gd, Tb–Yb, Yb–Gd) at various molar ratios. The optimal balance between green and NIR luminescence is achieved for the silica nanoparticles doped with Tb–Yb complexes at 2:1 (Tb:Yb) ratio due to both Tb(III) → Yb(III) energy transfer and specific distribution of Tb(III) and Yb(III) complexes within silica nanoparticles. The dual luminescent nanoparticles exhibit efficient cellular uptake behavior after amino-decoration of their surface, which is confirmed by confocal microscopy images of the cells incubated by the heterometallic nanoparticles
