Correlation of the Concepts truth, vérité, pravda, istina in Bible Versions: quantitative indicators
Authors: Fefelov A. F.
Published: June 2024

The paper is not about translation of the Bible into Russian, English or French, although its versions are widely presented in the research material. The goal is to compare the biblical discourse on truth and vérité with that of the post-truth era, its modern counterpart signified by the emblematic opposition of fact vs lies. Studying verbalizations of the above-mentioned concept has always been very important for the three cultures, but now, with a post-truth political ideology rising, its relevance for the English language and culture has increased noticeably. We study correlation of the words truth and vérité, pravda (often righteousness), istina (verity) in a number of Bible versions, old and new, to show that semantic consistency between the three cultures may be still achieved indirectly (that is without source texts) in this important area. Taking into account the factor of multiple versions has become essential for English-speaking cultures, it is quite important for the French community, and instructive for the Russian culture in terms of evaluating its consequences. The article presents only quantitative data on the density/variance (or dispersion) of concepts in the same biblical verse and the frequency of lexical ways of its verbalization in different versions of the Bible. The diagnostic value of frequency indicators for a meaningful interpretation is revealed, first, between the three languages; second, between the Old and New Testaments, and third, between their various books. To understand the functional load of the concepts under study in different versions, it is essential to know the frequency of their verbalizers, which sometimes differs greatly even within the same language for many reasons, including a new one – the task to produce a version easy to comprehend. It has been found that, as a rule, the degree of semantic correlation between the concepts under study is high, but in the “easy to read” versions a variability of lexical and syntactic means in the same contexts is significant as well as the intricacy of their refractions. This conclusion is valid, first of all, for the correlations of PRAVDA with its foreign-language counterparts. The form truths, which was not used in the early versions of the Bible, is now admitted by the most recent ones. This probably has to do with the secular philosophy of truth. And, finally, in the latest English-language versions, the word fact – the main competitor of truth in the discourse of the post-truth era – began to appear. This, however, does not refer to the word-combination fact-checking which still seems to be radically hostile to the Bible Truth discourse.

The paper presents the results of influence for manufacturing deviations from the shape of the flow part – cavities obtained during the refinement of the material part of the multistage axial compressor GTE-65.1. An approach to the mathematical description of cavities is described, consisting of four steps. This approach allows us to gradually determine the influence of the deviation on the characteristics of the compressor. For each of the four steps the integral characteristics of the compressor deviations in efficiency and the total pressure ratio are compared to the base geometry. The change in the stability of the compressor is analyzed, taking into account the cavities under consideration. The analysis of changes in the parameters of the compressor stages is carried out.

Published: June 2024

The article discusses one of the methods for reducing friction, used for newly developed rotary compressors as part of import substitution work. The experience of using rotary refrigeration compressors is analyzed and the main factors determining refrigeration capacity are identified. Methods used in aerospace engineering and power engineering to reduce friction and increase the service life of mechanical elements and assemblies using metallic and non-metallic materials have been identified, and the most promising materials and development trends have been analyzed. A fairly common method of reducing friction, based on the weariness effect, is chosen for study. Based on already known results, a technical solution based on the wear-free effect has been proposed to reduce friction of a refrigeration compressor with a rolling rotor.

The issue of creating a criteria base for the Hartmann–Sprenger pipe workflow based on a closed mathematical model is considered. On the basis of a closed mathematical model, the main parameters affecting the increase in the total temperature of the gas at the end of the dead-end cavity above the deceleration temperature of the incoming flow are recorded. Parameters with the same dimension are combined into one group so that only one dimensionless complex is obtained for all these quantities. Finding dimensionless complexes based on the modeling theory allowed us to determine the criteria base of the Hartmann–Sprenger pipe workflow.

Objectives:

The increasing incidence of chronic wounds such as diabetic foot ulcers and pressure ulcers, often compounded by bacterial infections and biofilm formation, presents significant challenges in wound management. Despite advancements in wound care products and a better understanding of molecular wound repair mechanisms, the treatment of chronic ulcerating conditions remains incomplete. VG111, a novel natural product formulation, emerges as a promising therapeutic candidate addressing the need for an effective wound healing agent with antimicrobial and tissue regenerative properties.

Materials and Methods:

A thorough evaluation of VG111 included antimicrobial assays to determine its minimum inhibitory concentration against an array of pathogens, assessment of its biofilm disruption capabilities, investigation into its profibrogenic activity through scratch assays, and analysis of its immunomodulatory effects on macrophage-derived cytokines. Quality consistency was ensured by high-performance liquid chromatography fingerprinting, while clinical applicability was assessed through observations in canine and human wound healing cases.

Statistical Analysis:

The cytotoxic effects of VG111 were assessed using a Two-way ANOVA, indicating no significant cytotoxicity at the tested concentration (Column factor p<0.0001).

Results:

VG111 demonstrated potent antimicrobial action with effective concentrations ranging from 2.5% to 5.0% v/v, targeting resistant strains of Methicillin-resistant Staphylococcus aureus, colistin-resistant Escherichia coli, Acinetobacter baumannii, and other priority pathogens. It showed biofilm clearance, enhanced fibroblast migration, and a favorable immunomodulatory profile by reducing inflammatory cytokines in vitro. In vivo applications corroborated these findings, with significant wound healing observed in both veterinary and clinical settings, negating the need for additional antibiotics.

Conclusions:

The study emphasized on VG111 as a robust wound healing agent with significant antimicrobial and biofilm-disrupting properties. Its broad-spectrum efficacy against critical pathogens and ability to promote tissue regeneration mark it as a promising avenue in the management of complex chronic wounds, meriting further clinical exploration.

Методами просвечивающей электронной дифракционной микроскопии и рентгеноструктурного анализа проведен сравнительный количественный анализ изменения фазового состава, дефектной субструктуры и перераспределения атомов углерода рельсов доэвтектоидной стали после длительной эксплуатации и деформации сжатием. Исследования рельсов проводились на разном расстоянии от поверхности катания в головке по разным направлениям, а сжатие осуществлялось до степеней 15, 30, 50 %. Показано, что длительная эксплуатация рельсов и деформация сжатием сопровождаются фрагментацией, причем, при выбранных режимах этот процесс идет интенсивнее при сжатии, чем при длительном нагружении. При анализе процесса фрагментации цементитных пластин привлечены представления об одновременном протекании механизмов разрушения движущимися дислокациями и растворения. Из зависимостей изменения объемных долей углерода в цементите и на дефектах кристаллической решетки от выбранных условий нагружения сделано заключение о преимущественной роли деформации сжатием по сравнению с процессом длительной эксплуатации. Выявлены физические причины немонотонного изменения скалярной и избыточной плотности дислокаций от степени деформации при сжатии и расстояния от поверхности головки по центральной оси и радиусу скругления выкружки и более высокие значения скалярной плотности дислокаций по сравнению с избыточной плотностью.
УСТОЙЧИВОСТЬ И ДЕФОРМАЦИОННОЕ ПОВЕДЕНИЕ КОМПОЗИТА НА ОСНОВЕ ЯЧЕИСТОЙ СТРУКТУРЫ: МОЛЕКУЛЯРНАЯ ДИНАМИКА

Published: June 2024

Композиционные материалы, состоящие из различных компонентов, объединенных физико-химическими связями, привлекают все большее внимание в связи с растущими требованиями к материалам. Поиск новых углеродных материалов, которые могли бы стать составной часть композитов, в настоящее время представляет большой интерес. В данной работе методом молекулярной динамики исследована устойчивость и деформационное поведение нового композитного материала на основе ячеистой углеродной структуры, заполненной никелем. Ячеистая углеродная структура представяляет собой соты, стенки которых – это графеновые наноленты. В результате была создана атомистическая модель композита и исследованы его механические свойства при 0 K и 300 K. В частности, исследована устойчивость при сжатии и анализ прочности при растяжении. Показано как происходит перераспределение металла внутри ячеек графеновой матрицы: ГЦК решетка никеля трансформируется под действием графеновых стенок и атомы никеля укладываются слоями, повторяя «рисунок» графеновой матрицы. В процессе двухосного сжатия происходит дальнейшее изменение укладки атомов никеля внутри сотовых ячеек, что приводит к формированию слоев никеля параллельно стенкам ячеек. Одноосное растяжение проводилось для трех типов материала – чистого никеля, ячеистой структуры, заполненной никелем и композита после двухосного сжатия. Было показано, что прочность композита значительно возрастает по сравнению с чистым никелем, при этом прочность обеспечивается именно углеродной сеткой. Влияние температуры на прочность слабое, как и влияние анизотропии структуры. Полученные результаты демонстрирую новый вид композитного материала, обладающего высокой прочность.
ВЛИЯНИЕ ТЕМПЕРАТУРЫ НАГРЕВА ЗАГОТОВКИ ПЕРЕД ТЕПЛОЙ ПРОКАТКОЙ НА СТРУКТУРУ И СВОЙСТВА ТИТАНОВОГО СПЛАВА ВТ22

Published: June 2024

Комплексно-легированный титановый сплав ВТ22 является высокопрочным сплавом, из которого изготавливают ответственные изделия авиакосмического назначения. Как правило, этот сплав используют в крупнозернистом состоянии и проблемными вопросами являются низкая технологическая пластичность и высокая нестабильность механических свойств материала в изделиях. Наиболее заметно эти проблемы проявляются при изготовлении тонкостенных полых конструкций. Последние можно успешно изготовить сверхпластической формовкой из листовых заготовок с мелко- или ультрамелкозернистой (УМЗ) структурой. УМЗ структура в листовых заготовках сплава ВТ22 может быть получена в результате изотермической прокатки. Однако изотермическая прокатка существенно удорожает производство, делая его экономически непривлекательным. В этой связи исследовали возможность получения УМЗ листов титанового сплав ВТ22 теплой прокаткой на холодных валках при температурах нагрева исходных заготовок в интервале температур 600-750 °С. Результаты проведенных исследований показывают, что листовая прокатка заготовок нагретых до температуры 600 °С позволяет получить УМЗ состояние в титановом сплаве ВТ22 с параметрами зеренно-субзеренной структуры менее 300 нм. Микротвердость полученных листовых заготовок выше на 20 % по сравнению с крупнозернистым сплавом ВТ22. Вытянутость зерен сплава вдоль плоскости прокатки уменьшается со снижением температуры нагрева заготовок перед прокаткой в исследованном интервале температур. Полученные данные могут быть полезными, в частности, для оптимизации условий получения тонких листов с УМЗ или нанокристаллической структурой.

Исследованы свойства сплава Ti-6Al-4V гидрированного (содержание водорода 0,002 масс. % и 0,23 масс. %), подвергнутому механическому разрыву (от 25 до 450 МРа), и облучению импульсной электронно-пучковой обработке потоком электронов с энергией 18 кэВ до 25 Дж/см2 и длительностью 15 мкс. В частности измерены термоэдс сплава при указанных воздействиях. Отмечена роль отдельных компонент алюминия и ванадия относительно изменения термоэлектрических свойств сплава. Представляют интерес не только стабилизация фаз, но и трансформация изучаемого сплава в слоистую среду, благодаря гидрированию и закреплению водорода в ловушках. Изменение коэффициента Зеебека S сплава Ti-6Al-4V для различных условий варьируется в интервале (от 0,003 до + 0,0011) мВ/K и сопровождается инверсией знака термоэдс, в частности для технического ванадия. Проведено сравнение значений термоэдс сплава Ti-6Al-4V со значениями термоэдс технического титана ВТ1-0 по изменение плотности состояний на уровне Ферми. Предполагается, что такого рода сплав может быть пригоден в силу стабильности и прочностных свойств для применения в системах контроля свойств имплантатов и нетрадиционной энергетики.

Наличие остаточного аустенита нежелательно в случае изготовления из стали ШХ15 деталей прецизионного назначения в силу того, что при эксплуатации неизбежно его превращение в мартенсит, следствием которого является изменение геометрических размеров деталей, что в итоге может привести к заклиниванию прецизионных пар, либо образованию трещин и выходу из строя прецизионного узла или агрегата. В настоящем исследовании показано изменение структурно-фазового состояния и микроструктуры закаленной конструкционной стали ШХ15 в зависимости от режима температуры отпуска и обработки холодом. Установлено, что стимуляция мартенситного превращения путем обработки холодом либо криогенной обработки приводит к дроблению аустенитных включений, незначительно снижая при этом общее содержание остаточного аустенита. Размер карбидных включений в случае обработки холодом либо криогенной обработки можно считать инвариантным, при этом общее количество частиц карбидных выделений увеличивается в 6,5 и в 8,4 раза соответственно в случае обработки холодом при -60 °С и криогенной обработке при -196 °С по сравнению с традиционной термической обработкой.

The impact of education system on economic growth
Authors: Tatarinova E. A.
Published: June 2024

The economic growth of a country is influenced by the high level of education. From the point of view of production function, the educational field with various activities can be categorised as a large industry with economic potential because it has significant scientific and human resources. The educational activity in the economic sphere is considered in two directions – the consumer aspect (short-term) and the investment-containing long-term development process. The ongoing educational process actively stimulates the economic growth when the young generation of students acquires modern knowledge, competencies and skills that ensure the future dynamic development of the country. The era of digitalisation has changed the mechanisms of interaction between economic structures, and therefore education should be a driving force of development. Consequently, it is at the origin of new innovative technologies of training. This is necessary to occupy the main positions in the field of scientific and technological progress. Higher education institutions and their activities have become a sector with a leading economic paradigm. The paradigm shift is causal. In order for education not only to exist, but also to be at a decent level, remaining the basis for the development of economic potential and society, it is necessary to make science the base, the foundation of all changes. The principle of “managing education in a business-like, scientific way, without turning it into a business” has become the main one in the context of transforming the educational sector into a modern, innovative sphere, meeting the requirements and needs of the evolving digital time.
Competitiveness of the enterprise on the market when developing new production
Authors: Chernov R. V.
Published: June 2024

The purposes of the study are to analyse competitiveness and develop recommendations for improving it when mastering production of new products. When reviewing well-known works where competitiveness has been studied, the author has examined the impact of changes at the macro level on the processes of developing new products by enterprises. In the article, the author has analysed various approaches to determining competitiveness. The influence of unilateral sanctions on competitiveness in the development of new products has been considered. At the same time, it is noted that sanctions as a tool of forceful pressure cannot be used as a tool for increasing success of enterprises in a fair competitive market. Therefore, the author highlights that the classical theory of competitive and non-competitive markets is not fully applicable in the current situation. In the works of some scientists, the competitiveness of an enterprise in the market that does not correspond to present realities has been analysed, and accordingly, such studies are not applicable in the conditions of a necessary fair competitive market. The author has suggested ways to determine both current competitiveness and its indicators in past and future periods. It is proposed to restructure the domestic technology transfer to the international one with friendly countries, moving from simple trade and exchange of goods to joint product development. Conditions are also needed within the country for scaling ideas and new designs. In an uncompetitive market, merging or associating companies for research, development and mastery the production of new products may be one of the ways to circumvent sanctions. Thus, the method is more applicable to technologies with a high level of digital and technological protection in the know-how mode.
Market of the Russian avant-garde painting: investment potential and characteristics of auctioning
Authors: Morozova D. L.
Published: June 2024

In Russia, art trading on auctions is considered to have features of the developing market that does not always follow global trends. Given that the potential of studying the national art market is not sufficiently fulfilled, the author has set the following purposes in this article: to study characteristics of investing in the Russian avant-garde artists and to build an econometric model (on the example of the “Knave of Diamonds” society). The Russian avantgarde is for the first time examined as an area forming general and unique pricing trends. The article analyses the peculiarities and trends of demand for avant-garde painting in 2000–2021, describes the geography of auction sales as well as the level of liquidity of art assets and provides price dynamics of the national and world markets. For these purposes, statistical analysis and visualisation are used, an econometric model is built using censored Heckman regression (Tobit-2). The average yield of M.Z. Chagall’s oil painting has been calculated in the article with the method of repeat sales. The nominal yield of his works, according to the author’s calculations, is 5.1 % which significantly lags behind the same indicator of financial assets. Investing in painting is viewed as a complex phenomenon with unique properties that distinguish the art market from other investments. The article is addressed to investment managers, bankers, collectors, appraisers, and specialists in economy of art.

Published: June 2024

The subject of this research is many conditions that contribute to the emergence of crisis phenomena in the financial and economic spheres. The purpose of the article is to study the causes, consequences, and prevention possibilities of financial crises. Among the methodology used, it is necessary to distinguish the analysis of internet-resources corresponding to the subject of the study, their synthesis and generalisation. The detailed analysis of the concept and causes of financial crises, systematisation of information about the possibilities of their avoidance are the main results of the conducted research. The obtained results can be applied in the development of methodologies and recommendations for the prevention of financial crises with consideration to the current situation as well as in the educational process. The prospects for further research on a given topic include: determination of the dynamics and specifics of the development of financial crises, the main development stages, formulation of forecasts about their occurrence in various economic sectors. In conclusion, we will note that, firstly, financial crises represent one of the integral stages of the development of economic relations both in a single country and in the whole world. Secondly, the causes of financial crises may be explained by using a certain theoretical framework with consideration to modern phenomena and, as a rule, are the result of the introduction of new tools, methods ,and ways of management. Thirdly, in order to increase the effectiveness of leveling the negative impact of financial crises, it’s important to apply the integrated approach which includes the implementation of preventive measures not only within the country, but also at the company level.
Bullying as an object of statistical research
Authors: Davletshina L. A. , Karmanov M. V.
Published: June 2024

The article discusses approaches to the definition of the “bullying” concept. Some peculiarities of interpretation of bullying have been established. It is often correlated with socialisation, deviant behaviour and health protection of the younger generations. In the course of examining the history of the given phenomenon as an object of scientific research, it was revealed that according to the first definition proposed in 1993 by the Norwegian psychologist D. Olweus, bullying is deliberate, systematically repeated aggressive behavior that includes inequality of social power or physical strength. Later, there was a division into bullying and mobbing. In the first case, it is about school violence against children, in the second – violence against the adult population. Consideration of bullying as an object of statistical research has determined that at present, bullying statistics are actually at an early stage of development, not allowing to assess such a specific object of research comprehensively, thoroughly and adequately. The paper proposes the concept development for a system of indicators of bullying statistics, identification and justification of its key sections and consistent filling of the latter with indicators that correspond to certain principles (openness, accessibility, etc.). In conclusion, it is extremely important to note that bullying is inadequate, immoral and, in fact, asocial attempts of personal self-affirmation, which bring the phenomenon in question to the level of extremely negative ones that arose historically and continues to exist and actively develop in the school environment. All in all, it requires further study and elaboration.
Studying the level and quality of life of the population on the example of Magnitogorsk, Chelyabinsk region
Authors: Ispulova S. N. , Makarenko E. A. , Proshkina A. A. , Sadovina D. E.
Published: June 2024

The authors analysed the system of measures at the federal and local levels aimed at improving the standard of living of the population in such areas as transport system development, affordable housing, demography, medicine, and salary. We conducted an empirical study using a survey method to determine the satisfaction of residents of Magnitogorsk, Chelyabinsk region, with the quality of life in the city and to identify the most pressing issues, the solution of which will help improve the standard of living of the city population. 330 adult men and women, residents of Magnitogorsk, differing in social status, participated in the survey (in the form of a questionnaire). Ultimately, the authors concluded that the quality of life in Magnitogorsk is low. Many residents are dissatisfied with the environmental situation in the city, the quality of medical care and financial income. This indicates that it is necessary to pursue a social policy aimed at solving these problems. At the same time, the majority of respondents highly appreciate the opportunities for a comfortable life: relatively cheap property, a sufficient number of places in kindergartens and schools, a fairly high level of professional education, employment and career opportunities.
Brand communication of Russian state corporations: conceptual approaches and current state
Authors: Faikov D. Yu. , Faikova S. D.
Published: June 2024

Unfriendly actions against Russia taken by the “global North” predetermine the need not only to strengthen defense capability and economic sovereignty, but also to expand international cooperation with other states. Strong brands of state-owned corporations, which have well-known successes at the global level, may help solve these problems. The purposes of the article are to formulate conceptual goals of branding of scientific and industrial state corporations and to assess their existing brand communications. Based on theoretical and legal analysis, it has been determined that such goals should be the following: the creation and maintenance of a strong corporate brand, the brand of a responsible employer, the brand of Russia as a high-tech country with advanced science and education that cares for the development of the population and territories. These brands should form the citizens’ confidence in strength of the state, patriotism. Empirical and content analysis has shown that state corporations, such as “Rosatom”, “Rostec”, “Roscosmos”, create systems of brand communications aimed at forming strong corporate brands and a positive image of the state. They include a wide range of contacts with audiences. Certain differences in brand communications have been identified for each state corporation related to the accents of missions and target audiences. It has been concluded that there is a need for a deeper assessment of the effectiveness of branding.

The article discusses examples of strong (SV > 0.7) simplest nonlinear dependencies in a problem for 114 indicators of 9 psychodiagnostic techniques, which represent exceptions in the context of many specific problems for studying statistical relationships, when two reciprocal dependencies, Y(X) and X(Y), are strong. There were only four such dependencies in the model for quintas of the independent variable within the framework of very weak and weak correlations (a total of 180 strong simplest nonlinear dependencies). The author quantitatively analysed and qualitatively interpreted the dependencies for three pairs of variables: “16PF-E: Submissive – Assertive” of R.B. Cattell’s questionnaire and “Competition” of K.W. Thomas’s methodology (SV = 0.78 and SV’ = 0.72 at r = 0.15); “16PF-Q3: Low self-control – High self-control” and “16PF-L: Trusting – Suspicious” of R.B. Cattell’s questionnaire (SV = 1.17 and SV’ = 0.91 at r = 0.28); “Psychasthenia” of the Minnesota Multiphasic Personality Inventory and “Suspicious type” of T.F. Leary’s methodology (SV = 0.84 and SV’ = 0.73 at r = 0.19). For the pair of variables “Low self-control – High self-control” and “Trusting – Suspicious”, models of linear regression are also considered. It is built on the basis of a dependence that is far from linear, as shown by Pearson’s coefficient of weak correlation equal to 0.28. At the same time, founded on the rule for interpreting the absolute value of the correlation coefficient for a sample of 120 subjects (widely used in the psychological community), it indicates the significance of the relationship at the p = 0.01 level, which inevitably requires a linear interpretation. For clarity, the information discussed in the article is illustrated by graphical representations of the dependencies under consideration.

The article analyses the role of immersive technologies in increasing productivity in enterprises. Economic growth is determined not only by productive forces, but also by the rational use of human labour and achievements of scientific and technological progress. The author has examined the experience of using digital tools relevant to the market that improve productivity – virtual and augmented reality. These technologies have a significant impact on labour productivity and contribute to enhancing performance indicators of production operations. The global practice of applying immersive technologies in enterprises demonstrates a wide range of areas of their use. Thus, augmented and virtual reality are in demand in mechanical engineering, energy extraction, logistics, design of facilities and production lines. In essence, these technologies expand the boundaries of human capabilities in interaction with virtual and augmented spaces, providing unique management tools for solving tasks of varying complexity, and have significant potential in the context of better productivity. Based on the results of the analysis, the key functions of augmented and virtual reality in industry have been identified, and the structure of the functional usage of immersive technologies to increase productivity has been developed.

Published: June 2024

The article provides a comparative analysis of the structure of funding sources for the national project “Ecology”. A comprehensive assessment of the interim results of implementing regional projects in the Vologda region was conducted as part of the national project in question using the method of earned value. As a result, a discrepancy was revealed in the structure of financial support for the implementation of the national project on a federal and regional scale both in sources and in items of expenditure, which is explained by the specifics of the goals and powers of different levels of management. In the Vologda region, low involvement of local governments and the private sector in the development of the national project “Ecology” was found. Underestimation of the target values of the results of project activities is indicated as a significant reason for the proven high efficiency of applying financial resources in the implementation of regional projects. To improve strategic environmental management, it was proposed to use stimulating measures for increasing the number of stakeholders and the amount of funding, to use a scenario approach. In general, the identified problems are typical for many constituent entities of the Russian Federation, therefore, the authors’ recommendations for their solution can be widely applied and will increase the efficiency of environmental activities and the quality of performance of the national project “Ecology”.

Water vapor condensation on hygroscopic aerosol particles plays an important role in cloud formation, climate change, secondary aerosol formation, and aerosol aging. Conventional understanding considers deliquescence of nanosized hygroscopic aerosol particles a nearly instantaneous solid to liquid phase transition. However, the nanoscale dynamics of water condensation and aerosol particle dissolution prior to and during deliquescence remain obscure due to a lack of high spatial and temporal resolution single particle measurements. Here we use real time in situ transmission electron microscopy (TEM) imaging of individual sodium chloride (NaCl) nanoparticles to demonstrate that water adsorption and aerosol particle dissolution prior to and during deliquescence is a multistep dynamic process. Water condensation and aerosol particle dissolution was investigated for lab generated NaCl aerosols and found to occur in three distinct stages as a function of increasing RH. First, a < 100 nm water layer adsorbed on the NaCl cubes and caused sharp corners to dissolve and truncate. The water layer grew to several hundred nanometers with increasing RH and was rapidly saturated with solute, as evidenced by halting of particle dissolution. Adjacent cube corners displayed second-scale curvature fluctuations with no net particle dissolution or water layer thickness change. We propose that droplet solute concentration fluctuations drove NaCl transport from regions of high local curvature to regions of low curvature. Finally, we observed coexistence of a liquid water droplet and aerosol particle immediately prior to deliquescence. Particles dissolved discretely along single crystallographic directions, separating by few second lag times with no dissolution. This work demonstrates that deliquescence of simple pure salt particles with sizes in the range of 100 nm to several microns is not an instantaneous phase transition and instead involves a range of complex dissolution and water condensation dynamics.

Electronic Lab Notebooks (ELNs) have become indispensable tools for modern research laboratories, facilitating data management, collaboration, and documentation of scientific experiments. However, the proliferation of diverse ELN platforms poses challenges for researchers who need to seamlessly exchange data between different systems. In this paper, we present ELNdataBridge, a novel server-based solution designed to address this challenge by providing a flexible adapter for interfacing and synchronising data between disparate ELN platforms. ELNdataBridge leverages Python APIs to interact with the underlying data structures of various ELN systems, enabling smooth transfer of information between them. The system offers a user-friendly interface that allows researchers to map and configure the transfer of single values and entry types between different ELNs, thereby facilitating interoperability and data exchange

This research investigates the electronic and dynamic properties of 2D qHP polymer sheets made of fullerene, with and without boron and nitrogen doping. Using density functional theory (DFT) with PBE and HSE functionals, including van der Waals in- teractions and classical simulations, we found that BN-doped qHP C60 materials exhibit enhanced conductivity and adsorption characteristics, demonstrating semiconducting behaviour with higher carrier mobility. qHP C58B1N1 shows ultra-high conductivity (∼ 1012 Ω−1cm−1s−1 at room temperature). These qHP sheets have cohesive energies of -8.75 (C60), -8.70 (C58B1N1), and -8.67 (C54B3N3), in the unit of eV, indicating greater stability than graphene and h-BN. Optical analysis suggests qHP C60 can absorb UV photons up to 1.1 eV, with a refractive index greater than one and an estimated optical bandgap of 0.95–1.65 eV. They have moderate direct electronic bandgaps and anisotropic mechanical properties, with Young’s modulus of 180-200 GPa. These struc- tures transition abruptly from elastic to fracture at a critical strain threshold, with similar thermal stability and melting points around 3900K.
