Effect of post-growth anneals in oxygen-containing atmosphere on the microhardness of single crystal calcium molybdate CaMoO4

Single crystal calcium molybdate CaMoO4 is a well-known material. However the interest to CaMoO4 has recently grown due to a number of its important applications including as a working material in cryogenic scintillation bolometers. CaMoO4 single crystals acquire blue color during growth due to the presence of color-center type defect centers which are unacceptable for optical applications. Color can be eliminated through annealing in an oxygen containing atmosphere, following which required optical components can be produced from the single crystals by mechanical treatment (cutting, polishing etc.). Therefore assessment of the mechanical properties of these single crystal materials is an important task for the optimal solution of issues occurring in the fabrication of optical components and their further practical application. There are but scarce data on the mechanical properties of CaMoO4, and the available ones have been reported without allowance for anisotropy. There is a significant scatter of data on the Mohs hardness of the single crystals, ranging from 3.3 to 6 in different publications. In this work we present data on calcium molybdate single crystals in the initial state and after high-temperature anneals of different durations in an oxygen containing atmosphere. We show that long-term annealing leads to decolorization of the crystals. Calcium molybdate single crystals prove to be quite brittle: the brittleness index Zp of the crystals in the initial state is the highest and equals 5, while annealing reduces the brittleness index to 4. The Palmqvist toughness factors S have been calculated The limit indentation destruction loads Flim have been determined and annealing in an oxygen containing atmosphere has been shown to increase Flim by 2.5 times for the Z cut and by 10 times for the X cut. The microhardness of the crystals has been shown to exhibit a II type anisotropy: the microhardness of all the specimens was higher for the Z cut than for the X cut. The microhardness anisotropy coefficients KH of the specimens have been evaluated. The bond ionicity degree I has been calculated on the basis of the experimentally measured microhardness

Review of effective methods of teaching a foreign language to university students in the framework of online distance learning: international experience

The research goal is to analyze the existing and most frequently used methods and competency-based approaches to distance learning of a foreign language. The tasks are formulated to achieve the goal. They involve classifying the methods of foreign language teaching based on the competency approach and identifying the effective methods. The methodological basis of this research includes methods of analyzing the practical experience of foreign language teaching based on a competency-based approach, synthesis of national and international experience, comparison of national models of the language environment, and generalization of sociological data. As a result of the conducted research, it has been revealed that among various methods, approaches related to information and communication technologies [ICT] are utilized most often. We believe that when teachers conduct courses using synchronous computer-mediated communication [SCMC] tools or platforms, students should be given opportunities to express their opinions. Most teachers recognize the creation of instructional videos as the most effective. According to the students, this type of activity also has the greatest learning effect and stimulates creativity. The scientific novelty of the research is the study of foreign language teaching methods based on a competency-based approach within the framework of online distance learning and the relationship of all interested parties, in other words, teachers, students, and educational institutions

Seasonal, synoptic, and diurnal-scale variability of biogeochemical trace gases and O2 from a 300-m tall tower in central Siberia

We present first results from 19 months of semicontinuous concentration measurements of biogeochemical trace gases (CO2, CO, and CH4) and O2, measured at the Zotino Tall Tower Observatory (ZOTTO) in the boreal forest of central Siberia. We estimated CO2 and O2 seasonal cycle amplitudes of 26.6 ppm and 134 per meg, respectively. An observed west-east gradient of about -7 ppm (in July 2006) between Shetland Islands, Scotland, and ZOTTO reflects summertime continental uptake of CO2 and is consistent with regional modeling studies. We found the oceanic component of the O2 seasonal amplitude (Atmospheric Potential Oxygen, or APO) to be 51 per meg, significantly smaller than the 95 per meg observed at Shetlands, illustrating a strong attenuation of the oceanic O2 signal in the continental interior. Comparison with the Tracer Model 3 (TM3) atmospheric transport model showed good agreement with the observed phasing and seasonal amplitude in CO2; however, the model exhibited greater O2 (43 per meg, 32%) and smaller APO (9 per meg, 18%) amplitudes. This seeming inconsistency in model comparisons between O2 and APO appears to be the result of phasing differences in land and ocean signals observed at ZOTTO, where ocean signals have a significant lag. In the first 2 months of measurements on the fully constructed tower (November and December 2006), we observed several events with clear vertical concentration gradients in all measured species except CO. During “cold events” (below -30°C) in November 2006, we observed large vertical gradients in CO2 (up to 22 ppm), suggesting a strong local source. The same pattern was observed in CH4 concentrations for the same events. Diurnal vertical CO2 gradients in April to May 2007 gave estimates for average nighttime respiration fluxes of 0.04 ± 0.02 mol C m-2 d-1, consistent with earlier eddy covariance measurements in 1999–2000 in the vicinity of the tower

Коронавирус SARS-CoV-2: гипотезы влияния на кровеносную систему, перспективы использования перфторуглеродной эмульсии, возможности биофизических методов исследования

This paper highlights published hypotheses on the possibility of coronavirus SARS-CoV-2 entry into the bloodstream, its interaction with vascular endothelium, red blood cells, hemoglobin and its fragments. As a result of such interaction, iron ions may be released into the bloodstream and, subsequently, a cytokine storm may occur. In this context, it is important to find a cytoprotective agent capable of blocking such processes. The perfluorocarbon emulsion could be a candidate for this role.The aim of the paper is to show the feasibility of biophysical methods to study the molecular mechanisms of action of SARS-CoV-2 on human red blood cells and hemoglobin as well as the restorative and cytoprotective effect of the perfluorocarbon emulsion during Fe2+ oxidation in heme.Materials and methods. High resolution spectroscopy, atomic force microscopy, atomic force spectroscopy, electroporation were used. Blood was exposed to oxidizing agents of different nature. Perfluorocarbon emulsion was added in various concentrations and its effect at various incubation times was studied. Concentration of hemoglobin derivatives was calculated considering multicollinearity, and statistical analysis of the results was performed.Results. The perfluorocarbon emulsion was shown to have an effective restorative and cytoprotective action in iron ion oxidation in the heme: Fe3+ was restored to Fe2+. The degree of MetHb reduction to HbO2 and Hb depended on the concentration of the oxidizing agent and incubation time. We observed a change in MetHb content from 80-90% to 5-12%. The perfluorocarbon emulsion in clinical concentrations helped eliminate local membrane defects and restored normal erythrocyte morphology.Conclusion. In the light of the studied hypotheses, the use of perfluorocarbon emulsion can become an effective method for blocking the consequences of coronavirus effect on the blood cells and restoring a normal gas exchange.В данной статье освещены опубликованные гипотезы, связанные с возможностью проникновения коронавируса SARS-CoV-2 в кровеносное русло, его взаимодействия с эндотелием сосудов, эритроцитами, гемоглобином и его фрагментами. В результате такого взаимодействия возможен выход иона железа в кровеносное русло и, как следствие, возникновение цитокинового шторма. В этом контексте представляется важным поиск цитопротекторов, которые могут блокировать такие процессы. Одним из таких препаратов может явиться перфторуглеродная эмульсия.Цель работы — показать возможности биофизических методов для исследования молекулярных механизмов действия SARS-CoV-2 на эритроциты и гемоглобин человека и восстанавливающее и цитопротекторное действие перфторуглеродной эмульсии при окислении иона железа в геме.Материалы и методы. Использовали спектроскопию высокого разрешения, атомную силовую микроскопию, атомно-силовую спектроскопию, электропорацию. Действовали на кровь окисляющими агентами различной природы. Добавляли перфторуглеродную эмульсию в различных концентрациях и исследовали ее действие при различном времени инкубации. Концентрацию производных гемоглобина, рассчитывали с учетом мультиколлинеарности, проводили статистический анализ результатов.Результаты. Показали, что при окислении иона железа в геме перфторуглеродная эмульсия вызывает эффективное восстанавливающее и цитопротекторное действие: Fe3+ восстанавливался до Fe2+. Степень восстановления MetHb до HbO2 и Hb зависела от концентрации окисляющего агента и времени инкубации. Наблюдали изменение содержания MetHb от (80-90)% до (5-12)%. Перфторугле-родная эмульсия в клинических концентрациях способствовала устранению локальных дефектов мембран и восстанавливала нормальную морфологию эритроцитов.Заключение. В фокусе рассмотренных гипотез использование перфторуглеродной эмульсии может стать эффективным методом для блокирования последствий воздействия коронавируса на элементы кровеносной системы и восстановления функционального газообмена
