Authors:   Yaroslavl branch of Financial University under the Government of the Russian Federation, Yaroslavl, Russia, Proskurnova K. Yu.
Published: December 2021

The topic relevance of the research is due to the fact that the identification of opportunities for the country spatial development and the strengthening the role of space in the national economy development necessitate the analysis of theoretical views how it is necessary to allocate productive forces, what factors affect the efficiency of using economic resources distributed in space, what possible options for building relationships between independent economic agents, depending on the territorial location. The purpose of the study is determining the role of institutions in identifying the conditions and opportunities for the spatial development of the state based on the analysis of the theories’ evolution of the productive forces’ allocation and spatial development. The main methods used in the study are content analysis and comparative analysis of theoretical views and practical approaches to the allocation of productive forces, spatial development of individual regions and the state. The paper presents an analysis of theories which contents factors that determine the approaches to the allocation of productive forces. Theories are considered in the temporal sequence of their emergence. The first group of theories is idealized and has not found its implementation in practice. The second group, represented by Soviet scientists, was practically applied during locating production throughout the country and was based on the institutions of a planned economy. The third group of theories arose in the conditions of institutions of a mixed economy and are the comprehension of facts and processes happened in practice. So, the second group of theories is presented as «theory — practice», and the third as «practice — theory». The direction of future research involves determining the place and role of institutions in the planning and implementation of measures for the spatial development of regions and the country.

In the so-called historical periods of artisanal and industrial development, craft, social, and cultural practices have gained a new position in history and thus in the modern scale of values, their own time and place in the new framework of the «green economy». The formal contradiction between crafts and modernization can be removed if we consider the historical experience of crafts. With their genetic link to trade masters and their workshops, small- and medium-sized enterprises can be drivers of innovation through conservational, ecological, and socially neutral productive processes. The article attempts to outline the theoretical and methodological basis of a social topology of crafts as a new sphere in the philosophy of history and trades. Drawing on ancient, western European and Russian philosophy, the authors show that the social topology of trades can be seen as an alternative theoretical and methodological basis when researching the history of crafts, the development of their form and their deployment in space and time. The timeliness and relevance of this theoretical discussion is defined by the need to answer the conceptual challenges of the space-time of post-industrial development, to open a new historical retrospective on crafts and to realize the current and future sustainable development of trades. A topological research agenda, where the historical personality is seen as a socio-bodily being with a place in the space-time it itself produces, is founded on the key concepts of corporeality and location and interconnectedness within the socio-ontological context. In the framework of social phenomenology and ontology, the schema of flexible networks of small manufacturers takes the following form: «trade fraternities — workshops — practices — the self-organization and self-administration of fraternities». The craft topologeme suggests cooperation within the framework of a global trade fraternity of ecological manufacturing networks.

Published: December 2021

To date, many issues concerning the process of forming and presenting integrated reporting, its structure and content remain unresolved. The presence of problem areas indicates the importance of further studying the theoretical aspects and practical experience of compiling integrated reporting, showing the ability of an organization to create value in the short, medium and long term. The purpose of the article is to study the current state of information creating and disclosure in integrated reporting in the context of fundamental concepts, guidelines and content elements of the International Integrated Reporting Framework. The object of the study is the public reports of Russian companies published in the National Register of Corporate Non-Financial Reporting. To study the current state of the formation of integrated reporting, an analysis of reports posted in the National Register by industry affiliation was carried out, on the basis of which it was concluded that the largest number of reports are submitted by Russian companies operating in the energy, metallurgical and mining industries. At the same time, the structure and content of the integrated reporting submitted by various companies is very heterogeneous, there are no uniform methodological approaches. The principles of forming reports regulated in the International Framework of Integrated Reporting are not sufficiently observed, which makes it impossible to assess the completeness and reliability of disclosure of information on sustainable development and social responsibility of companies. To determine the directions for improving the indicators of reports, the criteria for evaluating the quality of information presentation in integrated reports of companies are defined. 18 evaluation indicators were identified in accordance with the fundamental concepts, guidelines and content elements established by the International Framework for Integrated Reporting. The evaluation was carried out using a point-rating system by comparing evaluation indicators, on the basis of which reports were identified that most correspond in their content to the concepts and principles of the International Framework for Integrated Reporting. The scientific novelty of the research consists in substantiating theoretical provisions and developing practical recommendations for evaluating the content of integrated reports for compliance with international principles of formation, comparing the indicators of reports of various companies. The practical application of the developed approaches in the preparation and presentation of integrated reporting will allow companies to form reliable and complete information, to compare both in the time range within the organization and with other businesses of a similar profile.
FORMATION OF TARGET ATTITUDES AS THE BASIS OF THE CONCEPT OF A MULTILEVEL ECONOMIC ANALYSIS OF CUSTOMS PAYMENTS
Authors:   Orenburg State University, Orenburg, Russia, Popov V. V.
Published: December 2021

The article discusses the development of a set of targets for the economic analysis of customs pay¬ments. The relevance of the topic of scientific work lies in the fact that customs payments are the result of joint economic activities of economic entities participating in foreign economic activity and customs authorities, which makes it possible to interpret them as an independent economic category and an object of a separate economic analysis, as well as to identify a multi-level scientific problem, which can be solved in a complex possibly through a developed methodology of appropriate economic analysis based on a set of targets. Economic activity as its ultimate goal is the production or exchange of material goods or services, which can be carried out both within the country and abroad. If the first aspect is closely related to the production and economic activities of economic entities and the analysis of the relevant indicators reflecting this specificity through the use of the formed system of indicators (cost, profit, etc.), then in the second case the values that determine the very process of moving objects should come to the fore economic activity between the countries participating in the foreign trade transaction. The monographic method, as well as the methods of scientific philosophy (deduction and induction), should be singled out as the methodological approaches of the study, since taking into account the opinions of specialists in special¬ized areas will make it possible to most qualitatively develop the main strategic directions for the development of this type of sectoral economic analysis. As a scientific novelty, the developed target settings of economic analysis can be considered, which form the de¬sired image of the result of the economic analysis of customs payments in the researcher. The practical significance lies in the fact that the results and proposals of the work can be used both in the development of strategies for the development of the country’s foreign economic activity in the context of the intensification of international coop¬eration, as well as individual economic entities in the field of foreign economic activity, as well as the developed methodological approaches and scientific -practical recommendations for conducting sectoral economic analysis. The focus for further research is due to the high role of customs payments as an instrument of protectionist policy, as well as an integral part of the economic issues of international integration within the EAEU, as well as their stable component in the federal budget revenues (about 35% in 2020). The collection of customs duties at four levels made it possible to propose the author’s target setting of eco¬nomic analysis corresponding to each of its levels; As a result, the research prerequisites were grouped according to the scientifically grounded four levels of structuring.

The article presents a solution to the problem of choosing the brand composition of truck tractors for the recruitment of transport divisions of oil pipeline enterprises. The main task of transport departments is to meet the needs of the main production. The equipment is operated under harsh conditions, as well as after the end of the regulatory period of use and needs to be updated quickly. Despite the timely maintenance and repair of freight rolling stock, frequent failures and increasing repair costs make further operation economically inefficient. When updating the fleet of vehicles, there is a problem in choosing the best in terms of the technical characteristics of the vehicle, but at the minimum cost. The purpose of the study is to optimize the costs of acquiring and operating special equipment of Transneft-Siberia JSC by developing a methodology for determining the rational grade composition of truck tractors. According to the a priori ranking method, the opinion of specialists and heads of transport divisions of Transneft-Siberia JSC was determined. For the study, the most popular brands of truck tractors of domestic and foreign production were chosen. As a result of the survey, the ranks of operational indicators of truck tractors and their weight are determined by the reverse ratio. The most signifi¬cant indicator as a result of a priori ranking is the cost of one unit of the vehicle. Integral coefficient components calculated relative to average value of each indicator are identified for each indicator. As a result of the study, it was revealed that for the renewal of the fleet of truck tractors, it is advisable to give preference mainly to foreign manufacturers. The integral factor, taking into account the weight of operational parameters, makes it possible to objectively evaluate the quality of truck tractors. The method of determining the integral coefficient is proposed, when using which it is possible to reduce the cost of acquiring and operating vehicles with an increase in the development of special equipment. Further areas of research are determination of integral factors for the fleet, including technological transport, as well as determination of the optimal nomenclature of special equipment for transport divisions of oil pipeline industry enterprises.

The aim of the study is to increase the efficiency of vehicle operation by establishing patterns of change in the performance properties of winter tires and improving, on this basis, methods for adjusting the frequency of their replacement. The research methodology is based on the application of a systematic approach, a number of private methods of the experimental-theoretical level and proven methods of processing experimental data. As a result of the analysis of key factors, the relevance of the application of repair technology for studding car tires has been substantiated. Experimental studies on measuring the braking distance and acceleration time have confirmed the need for prompt diagnostics of the residual number of studs on car tires. It was found that the efficiency of the tire as the actual number of studs decreases non-linearly and depends largely on the type of road surface used. The scientific novelty of the performed research is the regularities of braking and acceleration properties of cars operated on various road surfaces in winter conditions, taking into account the technical condition of studded tires. The practical significance of such stands is to increase the demand for this service by reducing costs and significantly reducing labor costs associated with assessing the performance of winter tires. Technological operations using portable stands can be combined with periodic maintenance or carried out with a seasonal tire change both at service stations and in motor transport companies. Further research is aimed at collecting, analyzing and systematizing data to establish the parameters of mathematical models of the most popular standard sizes of automobile winter tires, which will allow scaling the technology and reducing its cost due to mass use. Thus, the results of the on-line diagnostics of tires can be used by car owners when making timely decisions about replacement or repair, which significantly increases traffic safety and reduces the cost of operation, since if the integrity of the tread is preserved, the restoration of winter tires with repair studs almost completely restores the original properties that determine numerical values of efficiency indicators at significantly lower costs in comparison with buying a set of new tires.

В данной работе мы представляем специализированный датасет, с разметкой мнений пользователей о репродуктивном поведении. Мы анализируем особенности распределение оценок «за» и «против» по конкретным аспектам репродуктивного поведения. Созданный датасет используется для решения двух задач классификации: классификации сообщений по релевантности изучаемых тем и позиции автора по той или иной теме. Для классификации сообщений используются классические методы машинного обучения, а также нейросетевая модель BERT. Лучшие результаты классификации в обеих задачах достигаются на основе вариантов модели BERT с использованием в классификации пар предложений — варианты NLI (natural language inference — вывод по тексту) и QA (question-answering — вопросно/̄ответный подход). Кроме того, созданный датасет позволяет сделать содержательные выводы по вопросам отношения пользователей сети ВКонтакте к вопросам репродуктивного поведения. Выявлено, что феномен сознательной бездетности активно представлен в сети, а многодетность остается слабо распространенной моделью поведения. В рамках пронаталистской политики важно формировать позитивное общественное мнение о родительстве, смягчать дефицит времени у родителей.

Published: December 2021

Não obstante já encontrarmos algumas mulheres que se destacaram como escritoras na Idade Média, algumas delas, inclusive, que trataram de temas relacionados a questão de gênero, como é o caso, por exemplo, de Hidelgard de Bingen (1098-1165), sendo por isso apontadas por alguns comentadores como precursoras do “feminismo”, mas é Cristina de Pisano (1365-143?), provavelmente, a primeira escritora “feminista” no sentido moderno da palavra. Participou ativamente do famoso movimento crítico-literário no medievo que ficou conhecido pelo nome de Querelle des Femmes, em reação a literatura misógina da época, que teve como estupim o famoso poema Roman de la Rose, escrito por Jean de Meung, em 1280. Eis, portanto, o objetivodeste artigo: apresentar Cristina de Pisano como uma fecunda precursora do movimento feministas moderno, destacando-se, inclusive, em comparação com outras importantes pensadores de seu tempo, por ter feito da arte de escrever uma profissão, e de a colocar a serviço da “causa feminina”.
Realidade dos Dois Mundos e Dois Cidadãos em Agostinho
Authors: Arruda Júnior Gerson Francisco , Lima Marcone Felipe Bezerra de
Published: December 2021

O conceito de livre-arbítrio e liberdade a partir de Agostinho tornou-se imo desde a Antiguidade Tardia e o Período Medieval, tornando-se um alvitre na contemporaneidade. A estrutura lógico-argumentativa do pensamento agostiniano acerca do arbitrium fundamenta-se na ontologia do homem, especificamente na sua constituinte metafísica – a alma (animus).  Em sua argumentação, o Hiponense considera a liberdade humana como elemento vinculado à razão, o que diferencia o homem dos demais seres, para os animais, anima e para aquele, animus. Portanto, considerando esse conceito ontológico, foram analisados os dois estados metafísicos do homem e assim seus dois mundos. Dessa forma, Agostinho conceitua o livre-arbítrio como elemento necessário que direciona a vontade para os bens superiores (eternos) ou para os inferiores (temporais), o que permite classificar os dois mundos e seus respectivos cidadãos.

The Turkey-UK Free Trade Agreement in Terms of Economic Diplomacy
Authors: Yiğenoğlu Kaan
Published: December 2021

This article scrutinizes relations between economic diplomacy and free trade agreements by focusing on the Turkey-UK free trade agreements which came into force in 2021. Accordingly, the article first introduces the concept of economic diplomacy, an important issue as it has been shown that bilateral trade agreements, nowadays preferred by many countries, can be used as a tool of economic diplomacy. The article then discusses the history and development of free trade agreements signed by Turkey, including its long-running experience of economic integration with the European Union. Although Turkey began establishing free trade agreements in the 1990s, it has been concentrating on and accelerating its use since 2000. Based on economic and political reasons underlying the free economic agreements, the reasons why Turkey and the UK have reached such an agreement are summarized. Economic relations between the two countries are then analyzed and the details of the agreement are investigated in the context of the changes that it provides.
The Turkey-Africa Bromance: Key Drivers, Agency, and Prospects
Authors: Dahir Abdinor
Published: December 2021

Turkish-African relations have consistently exhibited strong growth since Ankara declared 2005 as ‘the year of Africa.’ Turkey’s growing economic, political, and security involvement in Africa reflects Ankara’s need to establish new markets for its manufactured goods and its defense and armaments industry and present itself as a relevant regional and global actor different from traditional Western players on the continent. African countries have been astute in their engagement with Ankara in terms of exercising leverage in the evolving Turkish-African partnership. They seek to attract Turkish foreign direct investment, diversify economic and political partners to reduce dependency and fuel their state-building projects. Ankara’s domestic economic woes notwithstanding, Turkey’s growing footprint in Africa will likely continue to produce positive results for both sides.
How Algeria-Turkey Ambitious Strategic Rapprochement Will Affect France’s Sahel Policy?
Authors: Toumi Abdunour
Published: December 2021

President Macron did decide to withdraw French troops from the Sahel last summer, leaving only special forces based in north Mali, he stated that Operation Barkhane will end early in 2022. Nonetheless, Algiers’ decision to not allow French military planes to use Algeria’s airspace will create a direct impact on the military mission and France’s entire ‘war on terror in the Sahel. In Algeria, however, bold decisions toward a strategic rapprochement with Turkey were in the making. Even though the new authorities in Algiers were hesitant for such a foreign policy shift, because of the COVID-19 pandemic and the internal political struggle, constitutional and institutional amendments in the aftermath of the peaceful Algerian 2019 Hirak needed to be put in place. However, the tenacious resistance of the Francophile and Arabophone-nationalists anti-Ottoman legacy, the well-off social class, and elite pro-France lobbies in Algiers and Paris held back President Abdelmadjid Tebboune’s Administration from improving the relations between Algiers and Ankara. Meanwhile, the ambassadors from both countries have been pushing tirelessly for the success of the strategic rapprochement between these two states.
The Muslim Brotherhood Faultline in Saudi-Qatari Relations: Domestic Divisions and Regional Rivalry
Authors: Menshawy Mustafa , Mabon Simon
Published: December 2021

The commentary argues the Saudi-Qatari tensions lie in conflicting perspectives about the role of political Islam within the fabric of both states and their actions regionally. Funda-mentally, the rivalry stems from contrasting relations between political and religious elites in each country which has taken on an increasing political importance in tensions between Riyadh and Doha. Central to much of this are questions about the role played by the Muslim Brotherhood (and its various affiliates). More relatedly, the Saudi-Qatari rifts emerge out of competing understandings of authority and legitimacy, and with it, concern at the contesta-tion of these claims.
Exploring the Traits of a Grand Strategy for Turkey: Resilience, Protean Power, and Connectography
Authors: Yükselen Hasan
Published: December 2021

The international system is experiencing profound changes and has taken on an uncertain character as a result. The concept of strategy and its study has closely followed this trend, and new concepts have emerged both to adapt to and theoretically describe the practical changes and challenges it has engendered. This article explores the ill-suited features of mainstream debates and theorizing from a Turkish perspective and suggests that a critical realist analysis of agential strategizing is most useful to addressing the emerging context. It argues that Turkey has a long pursued grand strategy, but new concepts –resilience, protean power, and connectography– can enhance Turkey’s ability to strategize and can enrich the lately emerged vibrant debates exploring Turkey’s grand strategy.
Turkey’s Grand Strategy and the Great Powers
Authors: Aktürk Şener
Published: December 2021

How compatible is Turkey’s grand strategy with the grand strategies of global great powers? This article briefly summarizes principles of Turkish grand strategy, both from a descriptive and normative point of view, and then proceeds to outline and compare the grand strategies of five great powers that are permanent members of the United Nations Security Council (UNSC). While there are some observable conflicts between Turkey and the French, Russian, and American proxies in Syria, Libya, and the Caucasus, there are no outstanding militarized conflicts between Turkey and the British proxies. China is also positioned against Turkey in several international conflicts including Syria, and the intense persecution of Turkic Muslim Uyghurs in Xinjiang adds another dimension of latent Chinese-Turkish conflicts. The article provisionally concludes that the Turkish grand strategy seems to be most compatible, or least incompatible, with the British grand strategy, followed by the U.S. grand strategy, among the five permanent members of the UNSC, whereas Turkish and French and especially Russian grand strategies seem particularly incompatible.
The Intersection of Grand Strategies in Turkey-Russia Relations: Reflections of Smart Alignment and Flexible Competition in the International Arena
Authors: Zengin Alperen Kürşad , Topsakal İlyas
Published: December 2021

Evaluating Turkey-Russia relations is a dilemma, as the two countries fluctuate between perceptions of mutual historical hostility and strategic partnership. An alternative perspective is needed to get beyond the impasse of this dilemma. The main purpose of this study is to explain the common aspects of the grand strategies of Turkey and Russia within the framework of the pattern and to evaluate the policies of both countries in Syria, Libya, and the South Caucasus where the interests of both intersect and occasional conflict. We propose that Turkey-Russia relations can best be defined around the concepts of ‘smart alignment’ and ‘flexible competition.’ Their bilateral relations cannot be considered black or white in the abstract, but rather take place in the ‘gray zone.’ Alternative scenarios for the future of bilateral relations are presented in the conclusion.

Authors:   Academy of State Fire Service of EMERCOM of Russia, Spiridonov A. V.
Published: December 2021

Introduction. The paper presents the results of simulation based on monitoring data for the task of ensuring the safety of people. The initial data for the simulation was obtained using an experimental system for monitoring the distribution of people in the building. The simulation results indicate the possibility of accumulating reliable data on the distribution of people, which can later be used either as a source of initial data for the risk calculation procedure, or as a basis for the development of organizational fire safety measures at the facility. Goals and objectives. The purpose of this work is to develop a simulation technology based on monitoring data on the number of people for the task of ensuring their safety. For this, the following tasks have been successively solved: description of the simulation technology in relation to the task based on monitoring the number of people; construction of a simulation model, its validation and verification, as well as analysis and interpretation of the results obtained. Methods. To create and build a model of an object, the methods of simulation were used, in particular, the agent-based approach. Results and its discussion. The results of simulation showed the possibility of applying the proposed approach to the problem of assessing the distribution of the number of people in different zones of the floors. The constructed simulation model makes it possible to identify the most congested areas and premises in the building, being at the same time a tool for making well-grounded organizational decisions. Conclusions. The technology of simulation modeling has been developed, which will allow the decision-maker to conduct a better analysis of the congestion of premises inside the building, to identify critical areas inside the building that affect the safety of people. In addition, this approach can be applied as a basis for assessing the magnitude of fire risk. Keywords: fire safety, monitoring, simulation, AnyLogic, evacuation

Published: December 2021

Dual-energy computed tomography (DECT) has become increasingly available and can be readily incorporated into clinical practice. Although DECT can provide a wide variety of spectral imaging reconstructions, most clinically valuable information is available from a limited number of standard image reconstructions including virtual non-contrast and iodine overlay. The combination of these standard reconstructions can be used for specific diagnostic tasks that provide added value over traditional CT protocols. In this pictorial essay, the added value of these standard reconstructed images will be demonstrated by case examples for diseases specifically related to the gastrointestinal system.

On the Role of Solvent in the Formation of Vacancies on Ibuprofen Crystal Facets
Authors: Marinova Veselina , Wood Geoffrey P. F. , Marziano Ivan , Salvalaglio Matteo
Published: December 2021

Surface defects play a crucial role in the process of crystal growth, as the incorporation of growth units generally takes place on under-coordinated sites on the growing crystal facet. In this work, we use molecular dynamics simulations to obtain information on the role of the solvent in the roughening of three morphologically-relevant crystal faces of form I of racemic ibuprofen. To this aim, we devise a computational strategy based on combining independent Well Tempered Metadynamics with Mean Force Integration. This approach enables us to evaluate the energetic cost associated with the formation of a surface vacancy for a set of ten solvents, covering a range of polarities and hydrogen-bonding ability. We find that both the mechanism of defect formation on these facets and the work associated with the process are indeed markedly solvent-dependent. The methodology developed in this work has been designed with the aim of capturing solvent effects at the atomistic scale while maintaining the computational efficiency necessary for implementation in high-throughput computational screenings of crystallization solvents.
Interplay between shape and composition in bimetallic nanoparticles revealed by an efficient optimal-exchange optimization algorithm
Authors: Neumann Felix , Margraf Johannes T , Reuter Karsten , Bruix Albert
Published: December 2021

Despite the large relevance of bimetallic metal nanoparticles for heterogeneous catalysis, the relation between their shape and elemental composition remains elusive. Here, we investigate this relationship by implementing and applying global optimization methods enhanced with a novel optimal-exchange algorithm. In particular, we determine the lowest energy chemical orderings for PtAu nanoparticles, revealing that the most stable shape changes from highly symmetric structures for pure particles to distorted and less symmetric shapes for intermediate compositions. The presented method leverages the local atomic contributions to an empirical surrogate energy expression to identify optimal atom exchanges. This also allows us to pinpoint the origin of the stability of distorted shapes, revealing a favorable energy trade-off when over-coordinating Pt and under-coordinating Au upon distorting the particle shape.
TADF/RTP OLED organic emitters based on concaved N-PAHs with tunable intrinsic D-A electronic structure
Authors: Wagner Jakub , Zimmermann Crocomo Paola , Kochman Michał , Kubas Adam , Data Przemysław , Lindner Marcin
Published: December 2021

Polycyclic aromatic hydrocarbons (PAHs) with centrally positioned nitrogen dopants possess a unique curved structure and strong electron-donating features. However, the lack of tools to synthetically affect their bandgap engineering and charge-transfer (CT) characteristic is detrimental to their future optoelectronics use because of usually low PLQY effi-ciency. Facing this challenge, we report on developing the first fully conjugated, curved N-PAHs containing phenazine terminus with the D-A electronic structures, which are herein studied as functional optoelectronic material. We evidence the influence of curvature on minimizing HOMO-LUMO overlap, which was severely reflected in small ΔEST values, in-dispensable to enhance the RISC rate constant. Within this approach, we evaluate the utility of the concaved system as TADF/RTP emitters which has not been explored so far in the context of non-planar N-PAHs. By variable accepting strength of phenazines employed, the photoluminescence quantum yields (ΦPL) were tuned, ranging from the lowest 9% up to the highest 86% with dinitrile terminus. As a proof of concept, solid-state OLED devices were constructed, exhibit-ing yellow to orange emission with the best maximum external EL quantum efficiency (EQE) of 12% for acceptor built up on 3-(trifluoromethyl)phenyl decorated phenazine that is demonstrated for the first time for curved D-A embedded N-PAHs.

Porous metal-organic frameworks are a class of materials with great promise in gas separation and gas storage applications. Due to the large material space, computational screening techniques have long been an important part of the scientific toolbox. However, a broad validation of molecular simulations in these materials is hampered by the lack of a connection between databases of gas adsorption experiments and databases of the atomic crystal structure of corresponding materials. This work aims to connect the gas adsorption isotherms of metal-organic frameworks collected in the NIST/ARPA-E Database of Novel and Emerging Adsorbent Materials to a corresponding crystal structure in the Cambridge Structural Database. With tens of thousands of isotherms and crystal structures reported to date, an automatic approach is needed to establish this link, which we describe in this paper. As a first application and consistency check, we compare the pore volume deduced from low-temperature argon or nitrogen isotherms to the geometrical pore volume computed from the crystal structure. Overall, 545 argon or nitrogen isotherms could be matched to a corresponding crystal structure. We find that the pore volume computed via the two complementary methods shows acceptable agreement only in about 35% of these cases. We provide the subset of isotherms measured on these materials as a seed for a future, more complete reference data set for computational studies.

Проведено исследование процессов образования смешанных нанопорошков Al, оксидов меди и алюминия, прекурсоров для получения нанокерамик типа CuAlO и CuAlO при воздействии сдвоенных лазерных импульсов энергией 53 мДж и между импульсным интервалом 10 мкс на мишень, состоящую из пластинок алюминия марки АД1 и меди марки М2, склеенных между собой и помещенную в закрытую стеклянную прямоугольную кювету. Установлено, что последовательное воздействие серий сдвоенных лазерных на мишень из алюминия, а затем на мишень из меди приводит к многократному увеличению выхода субоксидов AlO, ионов и атомов алюминия и меди в лазерном факеле, направляемом на подложку, при напылении пленок, по сравнению с воздействием одиночными лазерными импульсами. Изучены процессы, происходящие на поверхности подложки при напылении пленок. Показана возможность получения прекурсоров для получения нанокерамик типа CuAlO и CuAlO.

A study of formation of mixed Al nanopowders, copper and aluminum oxides, and precursors for production of CuAlO and CuAlO nanoceramics under the influence of double laser pulses with energy of 53 mJ and the interpulse interval of 10 microseconds on a target consisting of plates of aluminum grade AD1 and copper grade M2, 0,4 mm thick, glued together and placed in a closed rectangular glass cuvette. It is found that the successive exposure of a series of double laser beams to an aluminum target and then to a copper target leads to a multiple increase in the yield of AlO suboxides, aluminum and copper ions and atoms in the laser torch, compared with the exposure to single laser pulses. To better understand the hidden mechanisms of this dependence, we study the processes occurring both on the surface and in the near-surface laser plasma inside the resulting microchannel when the target is broken by a series of single and double laser pulses. The possibility of obtaining precursors for the production of nanoceramics such as CuAlO, CuAlO is shown.

Теоретически проанализирована высокоскоростная деформация сплавов, содержащих зоны Гинье-Престона, в условиях высокоэнергетических внешних воздействий. Анализ выполнен в рамках теории динамического взаимодействия структурных дефектов. Исследуемый механизм диссипации заключается в необратимом переходе энергии внешних воздействий в энергию дислокационных колебаний. Получено аналитическое выражение динамического предела текучести с учетом всех структурных дефектов, содержащихся в сплаве. Показано, что в условиях высокоэнергетических внешних воздействий наноразмерные дефекты влияют на характер зависимости механических свойств от концентрации атомов второго компонента. Зависимость динамического предела текучести от концентрации атомов второго компонента становится немонотонной и имеет минимум. Выполнены численные оценки концентрации, при которой предел текучести становится минимальным. При таком значении концентрации происходит переход от доминирования торможения дислокации зонами Гинье-Престона к доминированию торможения атомами второго компонента.

The high strain rate deformation of alloys containing Guinier-Preston zones under high-energy external influences has been theoretically analyzed. The analysis was carried out within the framework of the theory of dynamic interaction of structural defects. The investigated dissipation mechanism consists in the irreversible transfer of energy of an external impact into the energy of dislocation vibrations. An analytical expression for the dynamic yield stress taking into account all structural defects of the alloy has been obtained. It is shown that, under high-energy external influences, nanoscale defects affect the nature of the dependence of mechanical properties on the concentration of atoms of the second component. The dependence of the dynamic yield stress on the atomic concentration of the second component becomes nonmonotonic and has a minimum. Numerical estimates of the concentration corresponding to the minimum yield stress has been made. At this concentration value, a transition occurs from the dominance of the dislocation drag by the Guinier-Preston zones to the dominance of the drag by the atoms of the second component.

Изучение оптических свойств наноразмерных мембран пористого анодного оксида алюминия позволяет значительно расширить области применения данного материала. В работе представлены результаты тепловизионных исследований мембран пористого анодного оксида алюминия с различными структурными параметрами. Построены профили распределения температуры для мембран, полученных в различных электролитах на основе серной, щавелевой и ортофосфорной кислотах. Установлено, что экранирование ИК излучения сильнее (примерно на 30%) проявляется у мембран с меньшим диаметром пор d ≈ 20 нм по сравнению с мембранами, у которых d ≈ 200 нм. Это связано с рассеиванием теплового излучения на неоднородностях структуры, которых значительно больше в мембранах пористого анодного оксида алюминия, полученных на серной кислоте. В качестве источников неоднородности выступают поры малого диаметра, недотравленные области и дефекты. Также, за счет повышенной активности серной кислоты по сравнению с другими используемыми кислотами большее количество анионов встраивается в структуру образца.

Study of optical properties of nanoscale membranes of porous anodic alumina can significantly expand the scope of this material. The paper presents the results of thermal imaging studies of porous anodic alumina membranes with various structural parameters. Temperature distribution profiles for membranes obtained in various electrolytes based on sulfuric, oxalic and orthophosphoric acids have been constructed. It was found that the shielding of IR radiation is more pronounced (approximately 30 %) in membranes with a smaller pore diameter d ≈ 20 nm compared to membranes with a larger pore diameter d ≈ 200 nm. This is due to the scattering of thermal radiation on structural inhomogeneities, which are much higher in porous anodic alumina membranes obtained with sulfuric acid. Small-diameter pores, under-etched areas and defects act as sources of inhomogeneity. Also, due to the increased activity of sulfuric acid in comparison with other acids used, more anions are incorporated into the structure of the sample.
