Published: January 2025

Catalysts are essential for sustainability because they decrease the energy and resource consumption in the production of high value-added products. The design of a novel catalyst is a challenging and expensive target, and a simplified methodology for catalyst development can trigger burgeoning progress in both academic and applied research. Here, we demonstrate a reaction network that autonomously yields the photoredoxcatalyst for transformation of the provided substrate under applied catalytic conditions. The system stems from the reversible condensation pathway leading to deazaoxaflavins, 2H-chromeno[2,3-d]pyrimidine synthetic analogs of flavins, with which they share photoorganocatalytic activity. We report on the photocatalytic activity of deazaoxaflavins and their covalently dynamic behavior. The reversibility principle allows for the exchange of one of the deazaoxaflavin constituents for a different moiety, thus leading to the adaptability of the catalyst. We argue that the observed phenomenon is of thermodynamic origin and thus can be applied to other photo/organocatalytic reactions, in which the combination of a suitable substrate and conditions are the governing principle for catalyst formation.

Published: January 2025

Mixtures of chemical ingredients, such as formulations, are ubiquitous in materials science, but optimizing their properties remains challenging due to the vast design space. Computational approaches offer a promising solution to traverse this space while minimizing trial-and-error experimentation. Using high-throughput classical molecular dynamics simulations, we generated a comprehensive dataset of over 30,000 solvent mixtures to evaluate three machine learning approaches that connect molecular structure and composition to property: formulation descriptor aggregation (FDA), formulation graph (FG), and Set2Set-based method (FDS2S). Our results demonstrate that our new FDS2S approach outperforms other approaches in predicting simulation-derived properties. Formulation-property relationships can reveal important substructures and identify promising formulations at least two to three times faster than random guessing. The models show robust transferability to experimental datasets, accurately predicting properties across energy, pharmaceutical, and petroleum applications. Our research demonstrates the utility of high-throughput simulations and machine learning tools to design formulations with promising properties.

Single atom catalysts (SACs) have revolutionized the field of catalysis achieving an unprecedented level of control and metal utilization for solid materials, approaching what is expected with molecular catalysts.1-3 Establishing structure-activity relationships for their wide-ranging applications requires precise elucidation of the metal coordination environment, which remains a grand challenge.1,2 While electron microscopy reveals atomic dispersion, only average coordination environments can be deduced from state-of-the-art spectroscopic methods used in heterogeneous catalysis. Here, we establish 195Pt solid-state nuclear magnetic resonance (NMR) spectroscopy as a powerful methodology to acquire NMR signatures across a series of Pt-SACs dispersed on carbon based supports. Monte-Carlo simulations allow the conversion of NMR signatures into SAC fingerprints that describe local coordination environments with molecular precision and enable to quantitatively assess Pt-site distribution and homogeneity. This methodology can track the influence of synthetic parameters, e.g., specific protocols, synthetic steps and type of supports, on Pt-SAC structures, to guide the reproducible development of SACs with targeted structures; it also enables to monitor the change of coordination environment of SACs upon reaction. Such development provides a blueprint for the quantitative assessment of larger SAC families containing other NMR-active isotopes.

Published: January 2025

The connection between magnetic field induced optical activity and chirality has a rich and complicated history. Although the broken inversion symmetry of chiral molecules generates ‘natural’ optical activity, magnetic optical activity is generated by breaking of time reversal symmetry. As a result, molecular chirality is not expected to influence magnetic optical phenomena, such as Faraday rotation. Here we show that the chiral supramolecular assembly of polymers can result in a large Faraday effect. This strong Faraday rotation, which is amongst the highest value known for organic materials, originates from the so-called Faraday B term. Typically, B term Faraday responses are weak. We demonstrate large amplification through excitonic coupling within the supramolecular assembly, where the chirality of the system controls the assembly formed. These observations provide an alternative means to enhance the Faraday rotation of low symmetry systems and clarify the role of chirality in previous reported materials. Tuneable magneto-optical phenomena in low-cost organic materials opens the door to applications including safety testing, bioimaging and quantum information processing
Uncovering the dynamic CO2 gas uptake behaviour of CALF-20 (Zn) under varying conditions via positronium lifetime analysis

Published: January 2025

Carbon dioxide (CO2) is a major greenhouse gas contributing to global warming. Adsorption in porous sorbents offers a promising method to mitigate CO2 emissions by capturing and storage. The zinc-triazole-oxalate-based metal-organic framework CALF-20 demonstrates high CO2 capacity, low H2O affinity, and low CO2 adsorption heat, enhancing energy efficiency while maintaining stable performance over multiple adsorption/desorption cycles. This study examines CO2 adsorption in CALF-20. Using the combination of positron annihilation lifetime spectroscopy (PALS), in situ-Powder X-ray Diffraction (PXRD) analyses, and gas adsorption experiments, we elucidate the CO2 adsorption mechanisms in CALF-20 under various temperatures, and humidity levels, simulating ambient conditions. The variable temperature PALS experiments demonstrate that CO₂ molecules are spatially localized within the CALF-20 cages, leaving temperature- and pressure-dependent gaps between them. PALS results indicate that CO2 initially spreads across cage centers, 1D chains, and ultimately adheres to pore walls. Interestingly, positronium intensity, which increases with CO₂ adsorption pressure, closely aligns with the Langmuir-Freundlich isotherm and reflects gas uptake behaviour. Moreover, we explore the adsorption characteristics of relative humidity (RH) and humid CO₂ in CALF-20. At low RH in pure humidity run, water molecules are sparsely adsorbed within the framework, forming isolated clusters or small oligomers with minimal hydrogen bonding. Above 35% RH, water molecules begin to form interconnected hydrogen-bond networks that fill the cages, significantly altering the material's free volumes. In humid CO₂ experiment, competitive interactions between CO₂ and water are observed, where CO₂ initially disrupts the propagation of water, but at higher RH, water molecules form more extensive hydrogen-bond networks. This competition influences both the cage and inter-granular spaces, with the latter becoming larger and more flexible as water fills the framework. The synergy between in situ-PALS, in situ-PXRD, and gas adsorption techniques provides a comprehensive understanding of CALF-20's potential for efficient CO2 capture under varying environmental conditions.

Published: January 2025

Computational studies of self-assembly have the potential to provide rich insights into their underlying thermodynamics and identify optimal system conditions for applications, such as nanomaterial synthesis or drug delivery. However, both self-assembly and supramolecular transitions can be hindered by free energy barriers, rendering them rare events on molecular timescales and making it challenging to sample them. Here, we show that the use of enhanced sampling techniques, when combined with a judiciously chosen set of order parameters, offers an efficient and robust route for characterizing the thermodynamics of self-assembly and supramolecular transitions. Specifically, we show that transitions between states with different periodicities or symmetries can be reversibly sampled by biasing a relatively small number of Fourier components of the particle density. We illustrate our approach by computing the free energy required to cleave a liquid slab and estimating the corresponding liquid-vapor surface tension. We also characterize the free energetics of the transition between spherical and rod-shaped droplets. These results serve as a first step towards the development of a systematic computational framework for exploring transitions in diverse supramolecular systems, such as surfactants or block copolymers, and characterizing the thermodynamics of their self-assembly.
Large-scale Atomistic Simulations of Lithium Diffusion in a Graphite Anode with a Machine Learning Force Field
Authors: Cheng Jianli , Stevenson James , Agarwal Garvit , Weber John , Jacobson Leif , Leswing Karl
Published: January 2025

Graphite is the anode material in the vast majority of current commercial lithium-ion batteries (LIBs) due to its excellent electrochemical performance and abundant reserves. However, the development of high-performance LIBs still faces technical bottlenecks including limited rate capability, partly because of the slow Li diffusion in the graphite anode. Experimental measurements of Li diffusivity versus Li contents in graphite show both monotonic and non-monotonic trends with reported Li diffusivity spanning orders of magnitude. Comprehensive insights of the Li diffusion process and its bottleneck in graphite are essential to develop the next-generation LIBs. In this work, we developed a machine learning force field (MLFF) to investigate the Li diffusion in the LixC6 system. We benchmark density functional theory (DFT) functionals and dispersion corrections versus experiment, finding nonlocal van der Waals functional rVV10 shows a good agreement with experimental results in terms of the structural, energetic, and electrochemical properties of the LixC6 system. We then train a MLFF based on our recently developed charge recursive neural network (QRNN) architecture to simulate Li diffusion in graphite at different Li contents, stage structures and temperatures. Our Li diffusion analysis demonstrates a phase-transition dependent Li diffusion in the LixC6 system, which supports the experimental measurements of a non-monotonic relation between Li diffusivity and Li content. This work demonstrates the capability of our QRNN model in carrying out large scale molecular dynamics simulations to identify the Li diffusion bottleneck in a graphite anode.

Authors: Baskar S. , Nivethaa E.A.K. , Kalkura Narayana
Published: January 2025

The significant characteristics of a bio-material are its biocompatibility, bioactivity and non-toxic nature. The immediate response from the living cells after introducing the crystalline bio-material into the human body determines its initial compatibility. The purpose of the implant material is to support the function of damaged or replaced tissue. It should be degraded after serving the purpose without causing any side effects, these are non-toxic materials. The crystals which possess the same physicochemical characteristics to that of the natural tissues/organ are generally highly compatible. The hydroxyapatite (HAp) in its crystalline form is similar in crystal structure and their chemical composition to that of the natural bone and hence it is employed in bone tissue repair applications. The methodologies and the mechanism involved in examining the biocompatibility is significant in fabricating crystalline HAp based composites for biomedical applications. The correlation between the physicochemical and biological characteristics of HAp crystals could be understood by performing the biological characterizations at various conditions.

Published: January 2025

Raman spectroscopy has become an invaluable tool in single-crystal studies, offering precise, nondestructive insights into crystal structures, electronic properties, and lattice vibrations. This method enables detailed analysis of crystal orientation, defect presence, and phase identity, making it indispensable for applications in electronics, optics, and advanced materials research. The simplicity of sample preparation, combined with its sensitivity to crystallinity and environmental factors, positions Raman spectroscopy as a powerful tool in characterizing materials for quality assurance and innovation in optoelectronics and photonic technologies. Despite its strengths, Raman spectroscopy faces certain limitations, such as sensitivity to laser-induced heat, fluorescence interference, and challenges in analysing metals. To address these issues, researchers have developed techniques such as controlled laser power, sample cooling, and alternative wavelengths to preserve sample integrity and clarity. The integration of machine learning further enhances the analysis of complex spectral data, opening new possibilities for rapid and accurate high-throughput applications. As such, Raman spectroscopy continues to evolve, enabling deeper understanding and broader applications across fields in materials science. This chapter explains the fundamental principles, advantages, and limitations of Raman spectroscopy in single crystal studies, while also highlighting recent advancements, including machine learning applications, that are enhancing its analytical power across various scientific fields.
Constructing competing discourses on the Russo-Ukrainian war: journalistic translation in wartime
Authors: Kamyanets Angela
Published: January 2025

This study employs critical discourse analysis to examine two opinion articles published in Western press that propose divergent strategies for the West in the Russo-Ukrainian war. The analysis focuses on three key aspects: representations of the war, evaluations, and dialogicality. The study also analyses Ukrainian journalistic translations of the articles. One article argues for equipping Ukraine with all necessary weapons for a swift victory over Russia, while the other supports incremental weapons supplies, leading to a prolonged war. The findings reveal that the former article portrays the war as Ukraine’s fight for independence and a battle to uphold international law, whereas the latter predominantly depicts it as territorial aggression that threatens global nuclear security. The former article employs a wide range of evaluative devices to underscore Russia’s brutality and condemn the delayed provision of Western weapons to Ukraine. In contrast, the other article primarily employs evaluative language to amplify fears of nuclear escalation. Regarding dialogicality, one author structures his text as an implied dialogue with hypothetical opponents, employing rhetorical questions, imperative sentences, irony, and first-person narration, whereas the other author references individuals with institutional authority to validate his assertions. The divergent treatment of these articles by the Ukrainian media, both at the macro and micro levels – reflected in the significant disparity in translations (12 to 1) and the manner in which the articles were reframed during translation – reveals the gatekeeping function of translation and suggests the Ukrainian media’s focus on positive news from the West as a means to keep up the country’s morale.
Eco-activist imagery in literary texts for children (a case study of English postmodern fairy tales and short stories)
Authors: Tsapiv Alla , Andrieieva Mariia
Published: January 2025

This research focuses on the eco-activist multimodal imagery in English postmodern fairy tales and short stories for children as a crucial tool in meaning-making. It is claimed that literary texts for children dynamically reflect current global trends in culture, environmental pollution, gender equality, and family issues. While some topics remain taboo for young readers, others are increasingly prevalent, gradually replacing magical worlds with more realistic, thought-provoking imagery. It has been observed that in recent years, the participation of young people and children in the eco-activist movement has been increasing. They advocate for environmental preservation and solving urgent environmental problems. Literary texts for children are essential tools for fostering a responsible attitude toward the environment at a young age. Due to them, child-readers are introduced to crucial eco-centric issues and ways of solving them and taught the consequences of their actions on nature.
The analysis of our case study reveals that the protagonists of eco-activist fairy tales are primarily children concerned about environmental issues. Shadow narratives and the point of view of the child-focaliser are realized by the visual means, i.e. visual metaphors, salience of definite objects on the pictures, interplay of colours and shapes. It has been observed that visual imagery expands, clarifies environmental protection issues and appeals to the better understanding of child-readers their role in preserving the planet and keeping it clean and safe for living. Visual components clearly show the child-reader the damage caused to the environment by human activity: polluted air, water bodies and cities, injured animals, and deforestation. Important meanings are embedded in the dominant colours of the illustrations: green and blue predominate in the illustrations of nature, while grey and black accompany the images of the results of anthropogenic activity. The victory of Good (nature) in fairy tales is represented by a shift from grey and black to green. Intertextual links between literary texts for children by the same author can be formed through illustrations. Thus, a single fictional world is created in which the eco-activist activity of a child-antagonist is not an isolated phenomenon.
South Кorea’s policy towards the European Union: main stages, features and development trends
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Ospanov Nurlan
Published: January 2025

The article examines the history of South Korea's policy towards the European Union since its formation. The purpose of the article is to study South Korea's policy towards European countries after gaining independence in 1948. It was important for South Korea to gain diplomatic recognition of independent European states. The article, based on South Korean and European materials, examines the policies of the presidential administrations of Rhee Syngman, Park Chung-hee, Roh Tae-woo, etc. The study used a descriptive method to capture the main points of interaction between South Korea and the EU countries. A realistic approach to international relations was used to analyze bilateral contacts between Seoul and Brussels, according to which states are primarily guided by their national interests when cooperating with other states. The study showed that Park Chung-hee, having become president of South Korea in 1962, intensified his foreign policy activities towards cooperation with developed Western European countries. He sought to attract investment into the economy, open the European market for South Korean business and isolate North Korea in the international arena. In the late 1980s, a thaw in the Cold War occurred on the international stage, which made it possible for South Korean President Roh Tae-woo to pursue his "Northern Policy" and establish contacts with the Soviet Union and Eastern European countries.

The author came to the conclusion that after the end of the authoritarian period in South Korea, political, economic and humanitarian ties between Seoul and Brussels are strengthening and expanding. In addition, the article reveals the contractual and legal relations between the European Union and South Korea, as well as trade disputes between South Korean and European businesses.

Points of view are often considered to be synonymous with perspectives. But when we study the structure of points of view in detail, we will find that perspective can be seen as a part of points of view. In this article, first, I consider my previous concept of points of view consisting of three elements: subject, object and aspect. Then I define frames in terms of cognitive science. After that, I will introduce an extended concept of points of view containing frames. In this new conception, perspectives are the ontological side of points of view.
UKRAINIAN MEDIALANDSCAPE IN THE TIME OF WAR (2022–2024): TRANSFORMATION, RESPONSE TO THE WAR, DYNAMICS OF MEDIA CONSUMPTION
Authors: Bezchotnikova Svitlana , Zrazhevska Nina
Published: January 2025

This article examines the impact of the Russian-Ukrainian hybrid war on the Ukrainian media landscape and media consumption. A mixed-method research methodology was used to reveal quantitative and qualitative changes. Despite losses in TV channels, radio stations and printed media, most media companies hadn't stopped broadcasting near war zone and launched united initiatives at the start of the war. Humanitarian media activities focused on crowdsourcing, fundraising, and information support for displaced people, army divisions, and the general Ukrainian public. The authors note that the peak of the humanitarian media campaigns for the war in Ukraine was during the first several months of the war. Most of the initiatives had long-term duration. The focus of crowdsourcing and fundraising campaigns, organized by the media, moved in dynamics primarily from people from the war zone who lost their work, home, and relatives in 2022-2023 towards army support and strengthening the defence of the country in 2023-2024. Increased news consumption through social networks was noted, with high trust in official sources like the President and Armed Forces. The media played a crucial role in national unity, with a strong emphasis on corporate social responsibility. Media consumption surveys identified disinformation narratives, strategies, and peculiarities of news consumption habits during the war.

The authors believe that the media has a powerful influence on the formation of people's views and beliefs. People look to the media for information and support to understand the situation and find ways to overcome a crisis. Monitoring media consumption during wartime is important for the analysis of the public's opinion about how they use the media, how they perceive restrictions on media use, who is responsible for fakes and disinformation, as well as which sources inspire confidence.

Published: January 2025

The study aims to explore the transformation of the role of the spokesperson in the digital age due to the expansion of the spokesperson’s scope of activities as a result of personal interaction with the public, the need to manage modern digital platforms, ensure consistency of messages and adapt to the new format and speed of news dissemination.

The article analyses the challenges that spokespersons face in the information space today, identifies the communication opportunities that spokespersons face in connection with the integration of digital platforms, and tracks the activities of the spokesperson for the President of the European Council, Ecaterine Casinge in terms of her activity on platform X to position the spokesperson and establish mutual understanding with the public.

To deepen the understanding of the role of the spokesperson in the modern information space, the authors used such research methods as statistical analytics, in particular, the content analysis method, to systematize and cover the spokesperson’s messages on a digital platform, such as a sample of the official account of the institution’s spokesperson on a social network. The content included press releases, social media posts, live video messages, and public engagement. The empirical basis of the study is the content of the social platform X from June 2023 to September 2024 by the spokesperson for the President of the European Council, Ecaterine Casinge.

The effectiveness of the spokesperson’s communication strategy was studied, which gave an idea of the level of audience coverage and interaction of the content with the public. The study provides quantitative indicators of the involvement of the target audience of Ecaterine Casinge to assess the effectiveness of her communication activities. It has been found that the spokesperson ensures that her messages are conveyed to the public through retweets of information materials.

The results of this study should be used to outline the future role of the spokesperson in the context of integrating artificial intelligence and virtual and augmented reality. The spokesperson of the future must balance new digital capabilities with the needs of the audience and act in a transparent, reliable and authoritative way.

It was determined that among the global trends in intangible asset management that determine the development of companies, the key ones are corporate reputation, responsible leadership, and sustainable development. Among the current trends in reputation management, the following are important: the presence of a higher goal of the corporate brand, high-quality communication with various groups of stakeholders as the basis of the business strategy, cybersecurity and data protection, the integration of artificial intelligence into work processes (including communication processes), and the ethics of its use.

Based on the analysis, recommendations were prepared to form an effective communication strategy for reputation management. The article's authors emphasize that the communication strategy for building and maintaining a positive reputation of the company should be based on a balanced system of communication channels and messages.

A company seeking to minimize reputational challenges and crises must necessarily work out possible options for reputational risks and develop scenarios for rapid response. An anti-crisis communications plan will allow one to act quickly and coherently during challenging times. At the same time, given the brittle and changeable situations in the BANI world, any plan must be adaptive and flexible.

Published: January 2025

The article analyzes the publishing series of the Ivan Franko National Literary and Memorial Museum in Lviv, the Franko House Library. This series has been published since 2017; 17 unique publications of various genres prepared by the Museum's researchers have been published. The series' repertoire includes scholarly and nonfiction publications and popular and children's books

The article focuses on three different publications about one of the most famous Ukrainian writers, poet, scientist, publicist, translator, traveler, and father of four children - Ivan Franko: a famous science biography "Dr. F. A Little Book about the Great Franko" by Bohdan Tykholoz, a catalog of the exhibition "Franko made in the U.S.S.R. " and a guidebook "Francomandry+". Each publication's content, structure, printing, advantages, and disadvantages intended for different target audiences are analyzed.
The article's topic is quite relevant because not many scholars have studied museum publications, particularly publishing series, and we can name only a few names: O. Mikhno, N. Cherhik, N. Liubovets, R. Mankovska, and others. As for Ivan Franko's biography, there are many articles, reviews, and publications about the writer, but the books of the "Library of the Franko House" series, as far as we know, have not yet been analyzed. Therefore, we can confidently insist on the relevance and importance of this topic.
General scientific methods of scientific research were used to achieve the research goal, namely analysis, synthesis, the method of analogy and concretization. The uniqueness, importance, and popularity of the publishing series "The Library of the Franko House", which meets the reading needs of the mass audience in learning about the life and work of one of the founders of Ukrainian identity, was proved.

An analytical review of Ukrainian and foreign literature on the study of manipulative technologies (strategies and tools) in social media was carried out. Observations are summarized and systematized by research objects and problems.

The variety of communicative strategies observable in today’s social media underscores the relevance of the chosen problem, particularly the distinction between "manipulative strategies"and "anti-manipulation strategies". This paper partially examines concepts such as "manipulative technologies", "manipulative strategies", "manipulation subject", "manipulation object", and "manipulation tools". It was found that the concepts of "anti-manipulation" and "anti-manipulation strategy" in the communicative aspect have not yet been developed in scientific works.

Using an information search method, the study selected relevant scientific literature focused onmanipulative strategies (1) and anti-manipulation strategies (2), in particular in social media. Through problem analysis, the main types of these strategies were identified. The descriptive method allowed for a detailed exploration of their characteristics. Given the military-political context, the paper analyzes key varieties of strategies: (1) disinformation strategies, propaganda strategies that create alternative realities, information operation strategies utilizing bots, doxing strategies, strategies for factual manipulation, ideological polarization strategies, and strategies that evade the truth and distort information, strategy "neglect, distort, distract, discourage"; (2) strategies for countering disinformation (strategy of technological solutions, development of media literacy, state and international initiatives), strategy of information security.

In conclusion, it is noted that manipulative technologies encompass a wide range of strategies, while the strategies of countering manipulations still require further theoretical development typological classification.

The article analyzes the impact of entertainment content on the psychology of citizens of a country at war. The challenges the authors of Ukrainian YouTube channels face are described, and the trends that should be followed to be heard are listed. The article emphasizes the adaptation of video content to the unfavorable conditions that have developed in our country and the importance of developing the Ukrainian-language segment on the YouTube platform.
The authors analyzed the content of the most popular YouTube channels based on the number of subscribers and views. By the beginning of 2024, there were 4.2 thousand YouTube channels in the Ukrainian segment of the YouTube space, which have more than 50 thousand views per month. A significant number of channels are based on entertainment content.
The article examines the prospects and expediency of producing entertainment content during the war. The authors emphasize that the war has created new challenges and opportunities for authors. At the beginning of 2022, authors had to change the subject of their videos, adapting to the realities of the time. However, in the third year of the full-scale war, the market stabilized, and now there is a clear trend toward an increase in the amount of entertainment content and its popularity in general. In any case, there are currently two ways to adapt entertainment content to war conditions. The first is to appropriately supplement such videos with an educational component, telling viewers about culture, language, or history. The second is to raise funds for the needs of the army. These methods allow authors to create high-quality, interesting entertainment content that the audience will positively perceive and support.
INTERNATIONAL BROADCASTING OF GREAT BRITAIN IN A GEOPOLITICAL CONTEXT
Authors: Tereshchuk Vitaliy
Published: January 2025

The article analyses the role of international broadcasting as a foreign policy tool in Great Britain and its transformation in the context of geopolitical changes. The relevance of this vector of research is based on the fact that for all the years of its existence, British foreign broadcasting has played a significant role both in the global media landscape and in the media spaces of most macro-regions of the world — European, Arab, African, etc. In addition, the formation of an image of the British National Broadcaster (BBC) as the benchmark of high standards of journalistic practice is undeniable. The purpose of the article is to reveal the role of the international broadcasting of Great Britain as a foreign policy tool and the features of the transformation of its goals and objectives under the influence of geopolitical imperatives. In order to achieve this goal, the tasks of identifying the stages of formation and development of the British foreign broadcasting system and finding out the influence of the geopolitical context on the transformation of the goals and target audiences of this broadcasting were implemented. It was revealed that the BBC World Service in different periods of its existence practised different models of broadcasting, realizing their inherent goals — colonial broadcasting (maintaining the unity of the British Empire), counter-propaganda in the interwar period and the period of the Second World War (countering informational influence alienation of Nazi Germany and the USSR), propaganda during the Second World War (formation of favourable public opinion regarding the activities of the anti-Hitler coalition) and the Cold War (anti-communist propaganda), in the times of the bipolar and post-bipolar world — positioning itself as a "surrogate" media that provides truthful news in countries where access to independent sources of information is limited by political regimes. As for the target audience, after a short period of purely colonial broadcasting, the objects of which were only British expatriates, the BBC’s international broadcasting has expanded to the indigenous population of the British colonies, as well as to the population of other countries.
