Technical aspects of the development of solar energy refrigeration technology on solid sorbents

Objective. The purpose of the study is a scientific review of the stages of development of refrigeration technology with sorption action on solid sorbents and an assessment of the current state of development of such household equipment in relation to the use of solar energy.Method. The dynamics of the development of solar energy refrigeration equipment based on sorption thermotransformers, the working vapors of which are solid sorbents and ozone-safe refrigerants, are analyzed. The beginning of development comes from the creation of periodic installations operating from the thermal energy of traditional energy carriers: hot water, burning of hydrocarbon or organic fuels, electric energy, and cooling with water and air and ends with modern refrigeration units operating from the energy of solar radiation and the daily temperature difference of the environment.Result. The peculiarities of making technical decisions underlying the design of the main devices of solar energy refrigeration units are noted. Circuit designs and operating principles of installations and their devices used to improve operating efficiency are described. The main trends in research conducted by scientists to improve the operation of solar energy thermal transformers of cyclic action are considered.Conclusion. This article may be useful to young scientists, engineers and designers for the design and development of innovative autonomous thermal transmitters and refrigeration units for cooling and short-term storage of products and medicines, obtaining food ice, air conditioning, operating independently from solar energy. Such installations are easy to manufacture and operate.

Recent Progress in Functional Nanomaterials towards the Storage, Separation, and Removal of Tritium.

Tritium is a sustainable next-generation prime fuel for generating nuclear energy through fusion reactions to fulfill the increasing global energy demand. Owing to the scarcity-high demand tradeoff, tritium must be bred inside a fusion reactor to ensure sustainability and must therefore be separated from its isotopes (protium and deuterium) in pure form, stored safely, and supplied on demand. Existing multistage isotope separation technologies exhibit low separation efficiency and require intensive energy inputs and large capital investments. Furthermore, tritium-contaminated heavy water constitutes a major fraction of nuclear waste, and accidents like the one at Fukushima Daiichi leave behind thousands of tons of diluted tritiated water, whose removal is beneficial from an environmental point of view. In this review, the recent progress and main research trends in hydrogen isotope storage and separation by focusing on the use of metal hydride (e.g., intermetallic, and high-entropy alloys), porous (e.g., zeolites and metal organic frameworks (MOFs)), and 2-D layered (e.g., graphene, hexagonal boron nitride (h-BN), and MXenes) materials to separate and store tritium based on their diverse functionalities are discussed. Finally, the challenges and future directions for implementing tritium storage and separation are summarized in the reviewed materials.

Вступительное слово

The special issue is devoted to the memory of professor Yuri Konstantinovich Kornilov. His works and pedagogical talent influenced the formation of several gene - rations of problem solving and creativity researchers. The twenties of the 20th century was the period of the beginning of experimental research into creativity and its comprehension as part of the experimental psychology of thinking. It is difficult to single out any particular date. It could be 1921, when W. Köhler's book Intelligenzprüfungen an Menschenaffen was published in German. It could be 1925 when this book was translated into English (The Mentality of Apes), and the subsequent publication that to a large extent ensured the wide popularity of the work and introduced the term Insight, still central to creativity research today. Or it could be 1926, which is the date G. Wallas published his work The Art of Thought, where he describes the basic stages of the creative process. Anyway, we have a century-long history of Insight Problem Solving research as an experimental paradigm of creativity research. Insight studies got a second wind in the 1980s, when the question of specificity of insightful solution in comparison with the processes of solving well-algorithmizable problems, described in the problem space theory by H. Simon, was raised. The search for specific mechanisms of insightful solutions has become a catalyst for the evolution of an independent and rapidly developing field of interdisciplinary studies, which has also been contributed to by Russian researchers. These are both scientists who worked during the classical period of research of thinking and creativity (S.L. Rubinstein, A.V. Brushlinsky, Ya.A. Ponomarev) and our contemporaries, whose texts are presented in this issue. The range of problems discussed in this issue reflects the main trends in insight research in recent years. This is a construction of theoretical models that allow us to explain the specific mechanisms of insightful solution, and identify factors that determine the specificity. This issue features articles by S.Yu. Korovkin; I.Yu. Vla - di mirov, A.V. Smirnitskaya, E.A. Shushkova (specifics of functioning of working memory subsystems at different stages of insightful solution); N.I. Loginov, V.F. Spi - ridonov (specifics of participation in the thought process of embodied knowledge); and E.A. Valueva, N.M. Lapteva; A.A. Medyntsev; T.V. Shumilov, A.V. Chisto - polskaya, I.Yu. Vladimirov (the role of emotions and metacognitive feelings in the regulation of insightful solution). Research methods of insightful solution, (especially important in the context of complexity), poor comprehension and the difficulties of recording the phenomenon under study, are equally presented here. For example, the paper by F.N. Markin and A.D. Savinova considers the potential and limitations of the task method for the laboratory study of thinking and creativity processes. The article by T.V. Shumilov, A.V. Chistopolskaya, and I.Yu. Vladi mirov raises the question of ways to improve the accuracy of self-reporting techniques for recording insightful solution events. The article by I.Yu. Vladimirov, A.V. Smir - nitskaya, and E.A. Shushkova discusses the possibility of combining behavioral and electrophysiological methods to study insightful solution processes. The articles in this issue not only reflect the current state of affairs in the field of insight research, but also identify the outlines for the further development of research. The authors hope that the material presented will be of interest both to colleagues engaged in the research on thinking, creativity, and cognitive processes and to a wide range of readers specializing in related studies and applied fields.

Morphometric and Nanomechanical Screening of Peripheral Blood Cells with Atomic Force Microscopy for Label-Free Assessment of Alzheimer's Disease, Parkinson's Disease, and Amyotrophic Lateral Sclerosis.

Neurodegenerative disorders (NDDs) are complex, multifactorial disorders with significant social and economic impact in today's society. NDDs are predicted to become the second-most common cause of death in the next few decades due to an increase in life expectancy but also to a lack of early diagnosis and mainly symptomatic treatment. Despite recent advances in diagnostic and therapeutic methods, there are yet no reliable biomarkers identifying the complex pathways contributing to these pathologies. The development of new approaches for early diagnosis and new therapies, together with the identification of non-invasive and more cost-effective diagnostic biomarkers, is one of the main trends in NDD biomedical research. Here we summarize data on peripheral biomarkers, biofluids (cerebrospinal fluid and blood plasma), and peripheral blood cells (platelets (PLTs) and red blood cells (RBCs)), reported so far for the three most common NDDs-Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). PLTs and RBCs, beyond their primary physiological functions, are increasingly recognized as valuable sources of biomarkers for NDDs. Special attention is given to the morphological and nanomechanical signatures of PLTs and RBCs as biophysical markers for the three pathologies. Modifications of the surface nanostructure and morphometric and nanomechanical signatures of PLTs and RBCs from patients with AD, PD, and ALS have been revealed by atomic force microscopy (AFM). AFM is currently experiencing rapid and widespread adoption in biomedicine and clinical medicine, in particular for early diagnostics of various medical conditions. AFM is a unique instrument without an analog, allowing the generation of three-dimensional cell images with extremely high spatial resolution at near-atomic scale, which are complemented by insights into the mechanical properties of cells and subcellular structures. Data demonstrate that AFM can distinguish between the three pathologies and the normal, healthy state. The specific PLT and RBC signatures can serve as biomarkers in combination with the currently used diagnostic tools. We highlight the strong correlation of the morphological and nanomechanical signatures between RBCs and PLTs in PD, ALS, and AD.

Medical Research Trends in Undergraduate Psychological Theses: A report from a South American country

Introduction: Psychological research can be conducted by researchers and by undergraduate or postgraduate students. At the undergraduate level, psychological research is especially challenging because of the limited ability of students to develop coherent and logical research problems and methodological approaches. Objective: This study aimed to identify the main research trends in undergraduate psychological theses at Peruvian universities. Quantitative and qualitative research design trends were identified as specific objectives. Methods: A descriptive and retrospective systematic review of psychological research thesis of Peruvian undergraduate students was conducted, starting the data extraction process starting with RENATI database for an initial screening phase. The data analysis was conducted in two phases. Results: The data were organized according to the following categories: sex of the authors, universities (1–5) according to their ranking, year of publication of the thesis, number of authors, designs, type of methodology, and topic of publication. Descriptive statistics were calculated on the basis of these categories. In the next phase, lexicometric and statistical textual analyses were used to identify research trends.

Risk factors for oral cancer: Thematic trends and research agenda

Context: Oral cancer is difficult to define due to several factors. It's known as oral squamous cell carcinoma (OSCC) and is common in the head and neck. Geographic variations in the impact of OSCC highlight the need for research on risk factors and treatment trends. Aims: To identify the main research trends of studies on oral cancer risk factors in the scientific literature in the Scopus database and Web of Science. Methods: This was an exploratory study of the risk factors for oral cancer designed considering the eligibility criteria defined by the PRISMA-2020 international statement, that is, inclusion and exclusion. Results: A total of 215 documents from Scopus and Web of Science were subjected to bibliometric analysis. The years 2020 and 2021 were the most productive, with 18 and 22 articles, respectively. The leading author in productivity and impact was Johnson N, the leading journal was Oral Oncology, followed by the International Journal of Cancer, and the main contributing countries were the United States, the United Kingdom and India. The main thematic cluster was composed of concepts such as Tobacco and Alcohol as the major risk factors; concepts such as Mortality or Head and Neck were positioned as emerging within the scientific literature. Conclusions: The main risk factors, i.e., alcohol and tobacco consumption, are relevant in terms of mortality in the consumer population, which is why their role should be determined in future studies.

Liberal Educational Implications of Korean Women’s Science Fiction in the 2010s : Focusing on Cheon Seonran’s <I>A Thousand Blue</I>

The emergence of women's science fiction in the 2010s is notable for its narrative achievements in imagining various possibilities of the ‘posthuman’ in the new reality brought about by the development of science and technology. Research on women’s science fiction has also been conducted in the context of the posthuman, with two main research trends: technofeminism, which affirms the union between women and science, and critical posthumanist research on ableism. However, these studies lack a perspective on animality that encompasses humans and nonhumans. The discussion of science fiction inevitably confronts the disregard for life and instrumentalist exploitation, which can be seen as increasing with the development of science and technology. Therefore, the issues of human and non-human minorities, vulnerability, and animality are the ultimate challenges of a posthuman society and are central to the discussion of science fiction. If posthumanism dreams of a ‘better’ post-human world, it should focus on ‘animals, including humans’. Therefore, in order to generate categories of thought for discussion topics that can be utilized in liberal arts education, this paper adds the animal axis to the existing discussion and discusses the correlation between the three concepts of minorities, vulnerability, and animality in Cheon Seonran’s science fiction novel <i>A Thousand Blue</i>. As we have seen, the educational implications of the novel are that it connects humans and animals through disability and points out the problems of the technological society that will come in the near future as an extension of today, pointing out that the posthuman society should be designed from the lowest position. In addition, the novel’s significance lies in the fact that it creates a point of debate, rather than simply sealing the issue by establishing a desirable human-animal relationship. The novel shows that by adding a species axis to the posthumanist discussion, we can start to think about how to redesign society.

Transportation Research Challenges Based on the Analysis of EU Projects

In recent years several projects have been realised in the field of transportation, but there is a lack of systematic analysis of research challenges connected to these projects. Thus, the main aim of this paper is to provide an overview of these challenges through EU funded projects in the field of smart, green and integrated transport. Based on EU strategic documents, reports and roadmaps, 10 topics are identified playing a crucial role in transportation-related research. A systematic analysis of the projects is realised, where the projects collected from an online database in the Horizon 2020 framework programme from 2015 to 2020 are categorised into these topics. The results show that travel behaviour, big data and open data, sustainable mobility planning and smart solutions are covered by several projects which reflect the main research trends. While active and shared modes, multimodal transportation, trip optimisation and Mobility as a Service are also popular topics. Based on the results, the most underrepresented research areas are artificial intelligence and social networks. The analysis of the connections between the research topics could enable the achievement of a long-term paradigm shift in urban mobility, which is beneficial for researchers, professionals and policy makers.

Product-Services for a Resource-Efficient and Circular Economy: An Updated Review

The development of product-service systems (PSSs) has become one of the most prominent ways in which to promote a circular and resource-efficient economy. These systems shift the focus from selling products as commodities to offering solutions that fulfil customers’ needs and provide added value. PSSs have gained attention due to their potential to foster sustainability, particularly in the context of the circular economy and resource efficiency. This review article analyzes the literature on PSSs for the period of 2016–2022, aiming to explore the links between PSSs, sustainability, circular economy, and resource efficiency. Close to 160 relevant articles were identified and examined. The overall findings reinforce contributions from previous studies, which denote a tendency towards sector-specific studies, barriers, and stimuli to implementation and adoption, and PSS design methodologies in specific industries and sectors. The overall results show a steady growth of PSS literature, as well as consistency in its definition, despite variations according to the perspective from which the topic is analyzed. This study focuses on eight main trends in PSS research, along with eight challenges that arise in its design, implementation, and adoption, identifying avenues for future research.

A Longitudinal History-Based Review of the Product-Service System: Past, Present, and Future

The research field of product-service systems (PSS) has experienced rapid growth since it emerged at the end of the 80s. Consequently, the conceptual structure of the PSS research field has expanded, and this phenomenon has driven novel research topics and future trends. This study analyzes the evolution and conceptual structure of the PSS research field since its emergence. A systematic literature review based on a bibliometric analysis was conducted, followed by a co-keyword analysis and content analysis, aiming to develop a historical overview of the nature of the research. The dataset involved 868 studies published between 1988 and 2022. The results present an analysis of the evolution of the literature in the following periods: (i) from 1988 to 2015, referred to in this study as the ‘past’, and (ii) from 2016 to 2022 (the ‘present’). A comparative analysis of the two periods is carried out, and the main topics and research trends and perspectives for future studies are identified (the ‘future’). Some of the main research topics include digitalization and sustainability, for which discussions on smart PSS, life-cycle management, ecodesign, knowledge management, development of assessment tools, simulation, and modeling technologies, have appeared. Research opportunities for future studies aligned with those topics are also identified, e.g., map key success factors to positive implementation of proposals that reconcile PSS with digitalization.

Interplays Between Artificial Intelligence and Sustainability in Business / Management. A Bibliometric Analysis

Abstract The paper aims to identify the main research (threads and) trends and evaluate the relationships between (and the impact of) the publications/articles investigating the interplays between artificial intelligence (AI) and sustainability against a business or management related context. To reach this objective, 863 articles from Web of Science Core Collection were analyzed, using VOSviewer as a bibliometric tool. Performance analysis was employed to mainly explore the interest and popularity of the topic, assess the main interest areas and fields of both the sources and the publications, determine the most relevant SDGs for the topic, and identify the most popular journals hosting articles in the analyzed field. Science mapping was carried out to identify the most influential articles in the field, understand the antecedent topics/ideas (in the fields of AI and sustainability, respectively) contributing to the emergence of a new interest area at the intersection between AI and sustainability, appraise the current developments in the analyzed interest area, and discover new trends / areas for future research.

Economic policy to support lifelong learning system development & SDG4 achievement: Bibliometric analysis

In order to set economic policy goals, it is important to understand the difference between adult education and lifelong learning, and how much research on SDG 4 combines lifelong learning and economic policy. The purpose of the article is to determine the main directions for justifying the lifelong learning system development, including for achieving sustainable development goal 4 (SDG 4). Based on scientific research data from the Scopus database using the VOSviewer software, this article analyzed the theoretical foundations for substantiating the temporal and geographical interrelationships of the categorical-conceptual system of such terms as “SDG 4”, “adult education”, “lifelong learning” and “economic”. This made it possible to identify the main trends in scientific research and cluster directions of international research on the relationship between adult education, lifelong learning and economic policy. The following trends were obtained: adult education as a driver of economic development; as a social phenomenon and as a source of innovation. The following clusters were identified: adult education as a part of life-long education; adult education under the influence of physical and age-related changes; adult education as part of professional education; the learning process, which is not related to professional activity. As a result of the analysis, an insufficient level of attention among scientific studies devoted to adult education within the framework of SDG 4 was revealed. The article confirmed the need for economic policy to support the lifelong learning system, as well as the difference between the concepts of adult education and lifelong learning.

Carrier Dynamics Mechanisms in Bi‐Based Photocatalytic Materials

Bi‐based nanomaterials have unique physicochemical and structural properties, allowing them to respond to visible light effectively. The Bi‐based semiconductors can be used for degradation of pollutants, reduction of CO2, nitrogen fixation, and decomposition of water, having the strong potential to address environmental pollution and energy shortages. However, the large‐scale application is still limited by the separation and transfer of electron–hole pairs. Herein this review article, carrier dynamics are studied from three perspectives, including structural modulation, atomic conformational reorganization, and surface modification. The relevant mechanisms of different strategies are mainly highlighted, the variations of carrier motion or lifetime are explored, and the progress in practical studies is elucidated. The structural modulation strategy is first introduced, including different dimensional structures and heterogeneous junctions. Further, the atomic conformational reorganization strategy is presented, including Bi‐rich strategies, doping, and vacancy defects. Additionally, the surface modification strategy is outlined, including facet engineering, loading of semiconductor cocatalysts, precious metals, or single atoms. Finally, these strategies are summarized for regulating carrier dynamics and the outlook with the main research trend, providing more inspiration for designing desirable Bi‐based semiconductors.

Mental Health in the Post-Lockdown Scenario: A Scientometric Investigation of the Main Thematic Trends of Research.

Since the outbreak of COVID-19, researchers and clinicians have published scientific articles on the SARS-CoV-2 virus and its medical, organizational, financial, and psychological implications. However, many effects have been observed in the post-lockdown scenario. In this study, we adopted a scientometric-bibliometric approach to drawing the state of the art regarding the emotional and psychological effects of the pandemic after the lockdown. In Scopus, we found 791 papers that were subsequently analyzed using CiteSpace. The document co-citation analysis (DCA) computation generated a network of eight major clusters, each representing a central area of investigation. Specifically, one major cluster-cluster no. 1-focuses on the long-term effects of the COVID-19 pandemic and individuals' ability to develop adaptive coping mechanisms and resilience. The results allow us to frame the fields covered by researchers more precisely and the areas that still need more investigation.

Circular Economy in Automobile Industry: Literature Analysis

With an increasing global focus on sustainability and reducing environmental impact, the concept of Circular Economy (CE) has become necessary for different sectors of the economy. This study targets the automotive industry as it is one of the major contributing sectors in the world. As there is a lack of review studies targeting the broader field of CE in the automobile industry it has become important to review CE concept literature to help future researchers determine future research directions. The aim of this paper is to present an analysis and better understand the concept of CE within the automotive industry. A systematic view is provided by reviewing, categorizing, and analyzing papers published between 2014 and 2023 on the Web of Science (WOS) database. Analysis of references is done through cataloging. This article investigates the main research directions and trends in terms of CE in the automobile industry and which element of the CE concept is becoming more popular while implementing CE practices. Through literature analysis, gaps are identified, and future research directions are proposed to fill them.

Trending Topics about Performance in Second Language Learning

This article recomposes the background of this theme during the decade 2001 to 2011. This study aims to discover ten main current research trends of performance in second language from 2012 to 2022. It will search scientific articles in the Social Science Citation Index (WOS) and in the Educational Resources Information Center (ERIC) databases and discover which are emergently compared to the previous decade. Finally, the study discusses these topic trends, other alternates and transversal-related issues. It presents a critical vision of the state-of-the-art of the last 20 years, considering reference publications. The method is a documentary review that selects ten scientific articles from the last decade to discover deep trends. This documentary methodology differs from a systematic bibliographic review in that it allows selecting and delving deeper into the qualitative content of the articles. The WOS database is the most relevant and prestigious database that collects journals. Thanks to the quality system implemented, the articles published in these journals included in this WOS database ensure significant studies that ensure scientific contributions and discoveries in the field. The main results are ten recurring topic trends with the previous decade on language learning programs, evaluation, teaching strategies, communication and psychological approach, digital devices, teacher action, cognitive approach, speaking performance, motivation and instructional performance language. The major conclusions highlight emerging interdisciplinary approaches to different variables and the adaptive study of emerging technologies, such as AI, without great interest in linguistic or economic policy issues. However, searches on other academic platforms find a broader open debate for two decades with other contextual parameters about economic factors and language policy, such as the literacy of immigrants in L2 as a factor of social and economic interest, the formal programming of a second language in institutions to obtain employment, especially in the professional framework of international mobility. This means that the WOS database collects general trends in this investigated topic. However, it only partially collects the breadth of scientific interest generated as a result of the needs of the socio-economic context. Funding This work belongs to the R+D+I Project, funded by a national state call titled Multiliteracies for adult at-risk learners of additional languages (Multi-Lits). It is supported by the Spanish Ministry of Science and Innovation and the State Research Agency [PID2020-113460RB-I00].

Identification of research gaps and systematization of trends on surface treatment in dental implants based on indexed data in the Scopus database

The installation of dental implants brings significant improvements in patient's quality of life, causing the demand for these procedures to increase. This growth results from the increasing use of innovative technologies in oral care. Since the 1970s, dental implants have continuously evolved, both in terms of shape and surface treatments. This evolution aims to improve osseointegration, an essential process for implant success, and prevent complications such as peri-implantitis. A necessary part of this evolutionary process is surface treatment on dental implants. This treatment improves implant surfaces' physical and chemical properties, promoting a more efficient interaction between the implant and surrounding tissues. To achieve this goal, modifications are made to the texture, composition, and characteristics of the implant surface. In this context, this study aims to identify the research gaps related to surface treatment on dental implants. To this end, a literature review was performed in the Scopus database using specific search terms related to this topic. The 20 most cited articles from 2017 to 2023, which address the main research trends in this area, were selected for analysis. The theoretical contribution of this study is to systematize the current research trends on the surface treatment of dental implants. This provides a better understanding of existing treatments and their limitations and presents ongoing studies that aim to overcome them. Furthermore, the research highlights studies under development, both in vitro and in vivo, that seek to apply scientific advances in clinical practice to improve implant outcomes. This applied contribution is relevant, as it can positively impact clinical practice and benefit patients.

A tutorial on discourse analysis in healthy and pathological ageing.

Age is a key factor when dealing with language and speech disorders, as it entails a progressive loss of neuroplasticity even in healthy individuals. Apart from this, ageing also affects our word-retrieval abilities, and thus, our discursive skills, particularly in people suffering from neurodegenerative diseases. Therefore, descriptions and/or measures of communicative performance always need to be interpreted through the lens of variation across the lifespan. This paper's main objective is to create a general tutorial for researchers willing to start delving into discourse analysis, both in healthy and pathological ageing. An eight-step tutorial on discourse analysis in the elderly is presented. Each of these steps starts with general recommendations and progresses to more specific topics that may be relevant when conducting this type of research. All of the steps have been extrapolated from an extensive literature review on discourse analysis. This work presents an easy-to-follow, step-by-step tutorial on discourse analysis in the elderly. It is aimed at clinical researchers who are taking their first steps in discourse analysis.It may also be useful for those who are already familiar with the methodology but may be interested in reading a general overview on the topic. Moreover, it offers new insights into the following topics: types of research questions, advantages and disadvantages of the different research methodologies and ethical considerations for data production in clinical linguistics. Discourse analysis in the elderly is a highly complex issue that may require researching from different approaches and disciplines. This implies following a well-planned and thorough process, which we have detailed through the following eight steps: (i) reviewing literature; (ii) formulating the research question; (iii) designing the study; (iv) producing data; (v) selecting technological tools for data treatment; (vi) transcribing the corpus; (vii) annotating the corpus and (viii) analysing and interpreting the results. What is already known on the subject Approaches in discourse analysis in elderly adults, and particularly, in people suffering from dementia have already been analysed by previous researchers and categorised into three main trends: the quantitative-experimental approach, the qualitative-naturalistic approach and an in-between path, the quantitative-naturalistic approach. Also, several handbooks on general discourse analysis have presented comprehensive revisions on potential resources and methodologies that can be applied to researching discourse in elderly populations. What this paper adds to existing knowledge This paper takes these three main approaches and analyses how the most recent research on language in ageing and dementia fits into them. Furthermore, it reviews the advantages and disadvantages each of them may bring for beginners in the field of discourse analysis. Moreover, it adds some studies that may fit into a fourth approach: the qualitative-experimental. This article also presents information about several of the main steps when analysing data from the pragmatic perspective: the formulation of the research question, data production and the transcription/annotation process. What are the potential or actual clinical implications of this work? This work has been devised for linguists who may want to read a systematization of the steps for analysing discourse in elderly populations. It may also be of interest to specialists from different fields such as speech therapy, psychology, gerontology or neurology who desire to start applying methods from discourse analysis in their work and aim to have a comprehensive scope of the main research trends within the field of clinical pragmatics.
