Authors: Сидоров Николай Васильевич , Теплякова Наталья Александровна , Палатников Михаил Николаевич
Published: December 2021

Методом ИК-спектроскопии в области валентных колебаний OH - групп выполнен анализ комплексных дефектов, обусловленных наличием в структуре кристалла водородных связей, в номинально чистых кристаллах ниобата лития конгруэнтного и стехиометрического состава с разным отношением Li / Nb, а также в кристаллах LiNbO: Zn(0,04 - 6,5 мол.% ZnO), легированных цинком в широком диапазоне концентраций, полученным по технологии прямого легирования расплава. Выявлено влияние легирующих примесей на концентрацию OH - групп, вид и локализацию комплексных дефектов в структуре кристалла. Показано, что изменение количества позиций атомов водорода в структуре кристалла LiNbO позволяет с достаточной точностью судить о соответствии его состава стехиометрическому или конгруэнтному составу. Для легированных кристаллов LiNbO : Zn(0,04 - 6,5 мол.% ZnO) получены данные, свидетельствующие об изменении при прохождении концентрационных порогов характера комплексообразования OH - групп с точечными дефектами катионной подрешетки. При этом, вследствие изменения механизма вхождения легирующего катиона в структуру кардинально изменяются свойства кристалла. Вклад в различие частот (и, соответственно, в значение квазиупругих постоянных связей OH -) в спектре конгруэнтного кристалла и легированных кристаллов может вносить также различие электроотрицательностей и ионных радиусов основных и легирующих катионов.

An analysis of complex defects was carried out by IR-spectroscopy method in the area of OH - groups stretching vibrations. The defects are caused by hydrogen bonds present in the structure of nominally pure congruent lithium niobate crystals, crystals of stoichiometric composition with a different Li / Nb ratio, as well as in LiNbO: Zn(0,04 - 6,5 мол.% ZnO) crystals doped in a wide range of concentrations due to direct doping of the melt method. Dopants were determined to influence OH - groups concentration, type and localization of complex defects in the crystals structure. A change in the amount of hydrogen sites in the LiNbO crystals structure was shown to evaluate the composition either stoichiometric or congruent. The character of OH - groups complexing with cation sublattice point defects was shown to change when doped crystals LiNbO: Zn(0,04 - 6,5 мол.% ZnO) trespass concentration thresholds. Dopant incorporation mechanism changes at this drastically, thus crystal properties also change quite sharply. Frequencies (as well as quasi-elastic constants of OH - bonds) change in congruent and doped crystals due to a difference in electronegativities and ionic radii of the main and dopant cations.

Кристалл ниобата лития, являющийся широко используемым и весьма востребованным в настоящее время нелинейно-оптическим материалом, примечателен своей способностью к варьирования широкого спектра сегнетоэлектрических и нелинейно-оптических характеристик в зависимости от типа и концентрации примесного иона, а также от соотношения Li / Nb . На основе разработанного нами подхода к моделированию кластеров в кристалле ниобата лития, в котором рост кластера идёт не элементарными ячейками, а кислородными октаэдрами, проведён сравнительный анализ особенностей внедрения в кристалл примесных ионов иттрия и бора с одинаковым зарядом +3 . Показано, что встраивание, вследствие различного ионного радиуса, идёт по двум механизмам: если для металла иттрия действует обычный механизм, когда примесной ион локализуется внутри кислородного октаэдра, то ион неметаллического элемента бора встраивается в тетраэдрические пустоты структуры, а именно в кислородные плоскости, образующие октаэдр. При этом влияние данных примесных ионов на одну из важнейших характеристик ниобата лития оказывается диаметрально противоположным: иттрий усиливает фоторефрактивный эффект, бор -понижает, что необходимо учитывать при направлении целевого использования кристаллов ниобата лития.

Lithium niobate crystals, which are a widely used and highly demanded as nonlinear optical material, are remarkable for their ability to vary a wide range of ferroelectric and nonlinear optical characteristics depending on the type and concentration of the impurity ion, as well as on the Li / Nb ratio. Based on our approach to modeling clusters in the lithium niobate crystal, in which the cluster grows not by unit cells, but by oxygen octahedra, we have carried out a comparative analysis of the features of the incorporation of impurity ions of yttrium and boron with the same charge +3 into the crystal. It is shown that due to the different ionic radii the incorporation proceeds by to two mechanisms. If for yttrium the usual mechanism operates, when the impurity ion is localized inside the oxygen octahedron. The ion of boron, i.e. a nonmetallic element, is incorporated into the tetrahedral voids of the structure, namely, into the oxygen planes forming the octahedron. In this case, the influence of these impurity ions on one of the most important characteristics of lithium niobate turns out to be diametrically opposite: yttrium enhances the photorefractive effect, boron decreases it, which must be taken into account in the direction of targeted use of lithium niobate crystals.

На базе электронно-статистического метода показана связь и проведена оценка поверхностной энергии и работы выхода электрона граней кристаллов лития с учетом дисперсионного, поляризационного и осцилляционного взаимодействия атомов поверхностного слоя. Считалось, что кристаллическая решетка не имеет дефектов. Модифицированы выражения поправок и аналитического соотношения, связывающего работу выхода электрона и поверхностную энергию с учетом типа кристаллической решетки и ориентации граней. Рассчитана работа выхода электрона и поверхностная энергия гладких граней при предельных температурах существования полиморфных фаз лития. Установлено влияние полиморфных превращений и температуры на анизотропию. Температурный коэффициент работы выхода электрона бездефектного кристалла положителен и составляет порядка 0,1-1 мэВ. Результаты расчетов хорошо согласуются с экспериментальными данными для поликристаллов.

On the basis of the electronic-statistical method, a relationship is obtained and the surface energy and the work function of the electron of the faces of lithium crystals are estimated, taking into account the dispersion, polarization, and oscillatory interactions of the atoms of the surface layer. It was assumed that the crystal lattice has no defects. The expressions for the corrections and an analytical relationship between the work function of the electron and the surface energy are modified taking into account the type of the crystal lattice and the orientation of the faces. The work function of the electron and the surface energy of smooth faces are calculated at the limiting temperatures of the existence of polymorphic lithium phases. The influence of polymorphic transformations and temperature on the anisotropy is established. The temperature coefficient of the work function of an electron in a defect-free crystal is positive and amounts to about 0,1-1 meV. The calculation results are in good agreement with the experimental data for polycrystals.

В данной работе исследуются закономерности структурообразования на примере биметаллических наночастиц Au - Ag, Ti - Al, Ti - V. Данные биметаллические наночастицы обладают различным размерным несоответствием и различной температурой кристаллизации. Проведены серии молекулярно-динамических экспериментов, по результатам которых проанализированы конечные конфигурации с наименьшей энергией и получены концентрационные зависимости энергии смешения. Анализ концентрационных зависимостей энергии смешения позволяет прогнозировать составы и размеры биметаллических наночастиц, которые могут проявлять нестабильность, как например для биметаллических наночастиц Ti - V. Асимметричность отдельных концентрационных зависимостей энергии смешения свидетельствуют о специфических структурных превращениях, характерных именно для данного состава и размера. Установлено, что для биметаллических наночастиц Au - Ag, Ti - Al характерна структурная сегрегация, и она активно проявляется при малых концентрациях более легкоплавкого компонента. Конкурирующими фазами в данном случае выступают ГЦК и ГПУ фазы. Кроме того, для средних из рассматриваемых в статье размеров исследована зависимость температуры кристаллизации от состава биметаллических наночастиц.

In this work, of the structure formation was investigated using Au - Ag, Ti - Al, Ti - V bimetallic nanoparticles as the patterns. These bimetallic nanoparticles have different atomic size mismatches and different crystallization temperatures. A series of molecular dynamics experiments was carried out. Based on their results, the final configurations with the lowest energy were analyzed and the concentration dependences of the mixing energy were obtained. An analysis of the concentration dependences of the mixing energy makes it possible to predict the compositions and sizes of bimetallic nanoparticles, which can exhibit instability, such as for Ti - V bimetallic nanoparticles. The asymmetry of individual concentration dependences of the mixing energy is evidence of specific structural transformations characteristic for the given composition and size. It has been established that structural segregation is characteristic for Au - Ag,Ti - Al bimetallic nanoparticles and it is actively manifested at low concentrations of a more low-melting component. The competing phases in this case are fcc and hcp phases. In addition, for the average sizes considered in the article, the dependence of the crystallization temperature on the composition of bimetallic nanoparticles was investigated.

В данной работе методом молекулярной динамики с использованием потенциала сильной связи проведено моделирование процесса молекулярно-лучевой эпитаксии с целью определения закономерностей при формировании фрактальных металлических пленок платины на поверхности родия. Установлена возможность формирования фрактальных структур как в островковых пленках платины на поверхности родия, так и в сплошной пленке. Установлены параметры компьютерного эксперимента, определяющие переход от отдельных островковых пленок к сплошной пленке в указанной системе. С использованием различных программных продуктов Gwyddion и Image Analysis, а также собственной разработки FractalSurface проанализирован диапазон изменения фрактальной размерности при различных условиях молекулярно-динамического эксперимента методом подсчета кубов. Полученные значения фрактальной размерности в целом находятся в приемлемом согласии между собой, однако существует ряд исключений, которые обсуждаются более подробно. Сравнительный анализ получаемых результатов позволяет формулировать рекомендации для методики создания, корректировки и прецизионного контроля при «выращивании» структур с заданной морфологией поверхности.

In this work, the molecular dynamics method and the tight-binding potential are used to simulate the process of molecular beam epitaxy in order to determine the regularities in the formation of fractal platinum metal films on the rhodium surface. The possibility of formation of fractal structures both in island platinum films on the rhodium surface and in a continuous film has been established. The parameters of the computer experiment, which determine the transition from individual island films to a continuous film in the indicated system, have been established. Using various software products Gwyddion and Image Analysis, as well as our own software FractalSurface, the range of changes in the fractal dimension has been analyzed under various conditions of a molecular dynamics experiment by the method of cube counting. The obtained values of the fractal dimension are generally in acceptable agreement with each other; however, there is a number of exceptions, which are discussed in more detail. A comparative analysis of the results obtained allows one to formulate recommendations for the methodology for creating, adjusting and precision control when «growing» structures with a given surface morphology.

Authors: Скачков Владимир Михайлович
Published: December 2021

В статье обсуждается изменение свойств диффузионно-твердеющего припоя в зависимости от состава жидкометаллической компоненты на основе легкоплавких сплавов галлия: галлий-олово, галлий-индий-олово и галлий-олово-цинк при взаимодействии с порошком сплава медь-олово (ПМОСФ5) подвергнутых низкотемпературной (125 °С) и высокотемпературной (500 °С) термической обработке. Механические свойства оценены измерением микротвердости, а термические исследованы методом дифференциально-термического анализа. Термическая обработка при высоких температурах способствует переходу припоя в равновесное состояние, при этом происходит значительное увеличение твердости. По графикам дифференциальнотермического анализа рассчитаны экзотермические эффекты. Методом рентгенофазового анализа определены образующиеся в результате диффузионного твердения фазы. Показано, что при различных температурах обработки образуются разные фазы - наноразмерные интерметаллические соединения. Экспериментально доказано улучшение механических свойств диффузионно-твердеющего припоя при наличии цинка растворенного в галлиевом жидком сплаве.

The article discusses the change in the properties of diffusion-hardening solder in dependence on the composition of the liquid metal component based on low-melting gallium alloys: gallium-tin, gallium-indium-tin and gallium-tin-zinc when interacting with the Spherical copper-tin alloy powder (SCTAP5) subjected to low-temperature (125 °С) and high-temperature (500 °С) heat treatment. The mechanical properties were evaluated by measuring the microhardness, and the thermal properties were studied by differential thermal analysis. Heat treatment at high temperatures promotes the transition of the solder to an equilibrium state, with a significant increase in hardness. The thermal effects of heat treatment of diffusion-hardening solders are calculated and compared. The phases formed as a result of hardening are determined by X-ray phase analysis. It is shown that different phases and nanoscale intermetallic compounds are formed at different processing temperatures. The improvement of the mechanical properties of diffusion-hardening solder in the presence of zinc dissolved in a gallium liquid alloy has been experimentally proved.

Authors: Голованова Ольга Александровна
Published: December 2021

Sr -замещенный трикальцийфосфат был получен методом осаждения из водных растворов. Синтетические твердые фазы исследовали с помощью рентгеннофазового анализа, ИК-Фурье спектроскопии, сканирующей электронной микроскопии, энергодисперсионного анализа. Надосадочная жидкость была исследована на наличие ионов Ca и PO для вычисления Са/Р соотношения. Выявлено, что ионы стронция входят в состав трикальцийфосфата, однако не изменяют его фазовый состав. Добавление ионов стронция в исходный раствор способствует уменьшению размеров кристаллитов и увеличению их пористости. Данные по энергодисперсионному анализу подтвердили, что ионы стронция входят в состав образцов ТКФ. Но при увеличении их концентрации, полного замещения ионов кальция на ионы стронция в структуре ТКФ не происходит. При изучении биорезорбируемости полученных образцов с помощью прямой потенциометрии установлено, что образцы, содержащие ионы стронция в своем составе, имеют меньшее значение скорости резорбции. При этом, наибольшие значения скорости растворения фиксируются в кислых средах.

Sr -substituted tricalcium phosphate was obtained by precipitation from aqueous solutions. Synthetic solid phases were investigated using X-ray phase analysis, IR spectroscopy, scanning electron microscopy, energy dispersive analysis. The supernatant was examined for the presence of Ca and PO4 ions to calculate the Ca/P ratio. It was revealed that strontium ions are part of tricalcium phosphate, but do not change its phase composition. The addition of strontium ions to the initial solution contributes to a decrease in the size of crystallites and an increase in their porosity. When studying the bioresorbability of the obtained samples using direct potentiometry, it was found that the samples containing strontium ions in their composition have a lower value of the rate of resorption. Energy dispersive analysis data confirmed that strontium ions are included in the composition of TCP samples. But with an increase in their concentration, complete replacement of calcium ions with strontium ions in the TCP structure does not occur. At the same time, the highest values of the dissolution rate are recorded in acidic media.

Актуальной проблемой в области адресной доставки лекарственных веществ являются аспекты, относящиеся к транспорту высокотоксичных препаратов, обладающих нежелательными побочными эффектами, в частности противоопухолевых. Были рассчитаны термодинамические параметры комплексообразования нанокластерного полиоксометаллата {MoFe}, перспективного в качестве средства адресной доставки лекарств, и широко применяемого в клинической практике цитостатика - доксорубицина. Взаимодействие доксорубицина с {Mo Fe} сопровождалось экзотермическим эффектом, что говорит об энергетически выгодном образовании комплекса. Кинетика процесса высвобождения доксорубицина из комплекса в буферном растворе с pH , соответствующим значению pH крови, была изучена методом люминесцентной спектроскопии. Были определены константы скорости процессов деструкции {Mo Fe} в комплексе, сопровождающейся высвобождением доксорубицина, и дальнейшего комплексообразования высвободившегося доксорубицина с продуктами распада {MoFe}. В будущем возможно управление скоростью высвобождения доксорубицина путем дополнительной стабилизации {Mo Fe}, например, путем его ассоциации с альбумином.

Actual problem in the field of targeted drug delivery is transport of highly toxic drugs, with undesirable side effects, in particular antitumor medicine. The thermodynamic parameters of complexation between nanocluster polyoxometalate {MoFe}, promising as a means of targeted drug delivery, and a cytostatic agent - doxorubicin, widely used in clinical practice, were studied. The interaction of doxorubicin with {MoFe} was accompanied by an exothermic effect, which indicates an energetically favorable formation of the complex. The kinetics of the release of doxorubicin from the complex in a buffer solution with a pH corresponding to the pH value of blood was studied by fluorescence spectroscopy. The rate constants of destruction processes in the complex, accompanied by the release of doxorubicin, and further complexation of the released doxorubicin with decay products were determined. In the future, it is possible to slow down the release of doxorubicin by stabilizing the {MoFe}, for example, when it is associated with albumin.

A vala clandestina de Perus: entre o passado e o presente
Authors: Teles Janaína de Almeida
Published: December 2021

A transição para a democracia no Brasil ocorreu sem rupturas evidentes. Sob a forte presença do legado ditatorial, a reconstituição factual e a reflexão crítica acerca do período autoritário permeiam-se por zonas de silêncio e interdições. Nesse contexto, a formação da memória sobre a repressão da ditadura teve dois eventos fundamentais, a publicação do projeto Brasil Nunca Mais e a abertura da vala de Perus. O objetivo deste estudo é jogar luz sobre a abertura da vala de Perus, evento “fundacional” que empurrou os limites da transição controlada do país, oferecendo um panorama reflexivo sobre a interdição do passado recente. Este panorama beneficia-se de entrevistas inéditas com pessoas diretamente envolvidas nesses eventos, documentos inéditos ou pouco explorados e uma ampla revisão da bibliografia existente sobre o assunto.

O presente artigo objetiva refletir sobre as possibilidades da Assessoria Jurídica (Universitária) Popular a partir de considerações desenvolvidas por membros do Núcleo de Assessoria Jurídica Universitária Popular Direito nas Ruas, vinculado Ã  Universidade Federal de Pernambuco. A metodologia do trabalho teve por base a análise de similitudes, divergências e reflexões observadas nos discursos de dois integrantes do Najup provocados, a partir de entrevistas, a promover considerações sobre a natureza das Ajups, as atividades desenvolvidas, as relações entre direito e educação popular, bem como as limitações das técnicas relacionadas a tais práticas. Essas análises estão situadas, ademais, no âmbito da atuação do Najup nas comunidades Esperança I, II e III, situadas na cidade de Recife, e demonstram como os próprios integrantes da AJUP vão refletindo sobre suas atuações, posicionamentos, limitações e possibilidades de melhora para aperfeiçoar o trabalho popular. Se trata, portanto, além de um histórico da atuação do grupo com essas comunidades, de um levantamento da percepção dos membros, o que se revela fundamental para compreender como as concepções e conceitos associados Ã  assessoria jurídica popular vão evoluindo e modificando na construção prática.

Para além da igualdade
Authors: Borrillo Daniel
Published: December 2021

O modo como são articuladas as novas reivindicações do movimento LGBTI nos países ocidentais, a partir do fim dos anos 1980, corresponde Ã  uma mudança no paradigma da mobilização política, tanto pela explosão da AIDS como pela crescente globalização. Essa mudança pode, efetivamente, ser explicada, ao mesmo tempo, pela urgência instalada pela explosão do HIV e pelo fim da utopia revolucionária, fruto da globalização pós-comunismo. Essas situações resultaram nas novas formas de mobilização social pelas novas demandas políticas. O reconhecimento dos direitos das pessoas LGBT’S é resultado de uma intervenção ”“ tanto no nível nacional como internacional ”“ de muitos atores dentre os quais, as associações de luta contra a AIDS desempenharam o papel principal. Diferente da ação política dos militantes dos anos 1970, as disputas dos anos 1990 e 2000 não se articulam mais em torno de uma oposição Ã  sociedade e aos valores burgueses, mas em função da igualdade de direitos.

Authors: Feng Zhixin , Wang Shang , Wang Xuelei
Published: December 2021

Based on the needs of regional industrial development and technical personnel training, the training base for technical skill as the core function has effectively enhanced the development of vocational education. However, at present, the training base in vocational colleges is mainly applied for students’ teaching, and the overall utilization rate is low. It is of great importance in the rational application of software and hardware resources onto the training base to widely carry out popular science activities. The importance of training base construction and scientific popularization is expounded. On this basis, the research team took the S&T racing training base as a case to study its expandable scientific popularization function. The practice results show that using the resources of the training base to carry out scientific popularization activities can greatly improve teenagers’ interest in automobile technology. More training bases in vocational colleges should expand the function of scientific popularization.

Authors: Năznean Adrian
Published: December 2021

The COVID-19 pandemic forced the closure of many human activities. As a result, education quickly shifted from a classroom setting to an online one, challenging educators and students alike. Multiple issues that had barely been known to educators surfaced: technophobia, lack of rules or guidelines regarding online learning, politeness in a virtual environment, limited social interaction, but some of the greatest challenges remain cheating, and academic integrity concerns during online examinations. Technological and software advances can oftentimes identify cases of academic dishonesty. However, with mass education and faculty unpreparedness it is rather problematic to combat and avoid cheating during online assessment. This mixed-methods review based on the limited empirical research on the topic of cheating during online examinations will identify the factors that lead to cheating and will discuss the best ways of combating and avoiding academic dishonesty.

Collisions of Local and Spiritual in State and Public Activities of Metropolitan Ilarion (Ivan Ohienko)
Authors: Bondar Serhii
Published: December 2021

The article clarifies the views of one of the brightest and most significant figures of the Ukrainian church — Metropolitan Ilarion (Ivan) Ohienko on the spiritual and secular service to Ukraine and his practical activities, which naturally effectively combined these two aspects. This article notes that an important element that united the two ministries and substantiated them was the deep level of their interpenetration, where Orthodoxy acquired a national character based on traditions. The article concludes that during this ministry his views on the church did not undergo nonlinear evolution, but only acquired depth and system. Even when Ivan Ohienko was in public office or abroad, he attached great importance to moral, ethical and ecclesiastical issues. Despite the ideological closeness with the views of another prominent Ukrainian church figure Andrei Sheptytsky on church-state relations, education and revival of the Ukrainian nation, language and culture as factors of Ukrainian identity, Ivan Ohienko was still skeptical of the Ukrainian Greek Catholic Church, seeing in it is an instrument of Catholicization of the Ukrainian people. Ohienko believed that in reality only an autocephalous church could be Ukrainian, which relied exclusively on the traditions and needs of the people. This was the criterion of the truth of Orthodoxy for him.
Problems of Foreign Policy Choice of the State Center of the Ukrainian People’s Republic in 1939–1940
Authors: Yablonskyi Vasyl
Published: December 2021

The Second World War was viewed by Ukrainians abroad and in Ukraine as a potential chance to restore Ukraine’s independence. At the beginning of the war, the main political forces of the Ukrainian emigration interfered in a state of mutual confrontation. Each of them tried to attract international contacts for support. The article examines the process of finding foreign policy allies by the State Center of the Ukrainian People’s Republic in exile at the first stage of World War II (1939–1940). The main attention is paid to the political processes in this part of the Ukrainian emigration, the disunity and the presence of three governing centers (in France, Czechoslovakia and Poland) and the foreign policy orientations of the emigration government of the Ukrainian People’s Republic. For the first time, the document”Letters from the leading circles of the UPR” is published, which attempts to justify the need for a foreign policy alliance with Germany and criticizes the “francophilism” of some figures of the State Center of the UPR in Europe and America. The hypothetical circle of emigration politicians who could be the authors of these documents and their addressees is outlined. Attention is drawn to the fact that the conclusion of foreign policy agreements with Germany in the interwar period was a well-established practice for many countries at that time (France, England, the USSR, etc.). The reasons for the disinterest of the main players in world politics at this stage in the restoration of Ukraine’s independence are emphasized. As the government’s emigration status and military actions did not help preserve the archives, documents belonging to this period of Ukrainian history and diplomacy have come down to us in limited numbers. Publication and analysis of documents of the Ukrainian People’s Republic in exile, which relate to the foreign policy concepts of the Ukrainian emigration government, allow to more fully reveal the vision of ways to restore Ukraine’s independence after its territories were part of the USSR, Poland, Romania and Czechoslovakia.
