OBJECTIVE: To present the research status of carbon nanomaterials in biomedical field, reveal the main research subjects, explore the research hotspots and development trends, and provide a reference for the future development of this field. METHODS: The core data set of Web of Science was used as the literature source to search the relevant researches on carbon nanomaterials in the biomedical field from 2012 to 2023. The knowledge map was generated by using Citespace software with countries, institutions, authors, keywords, and co-citations as nodes and for visualization analysis. RESULTS AND CONCLUSION: (1) A total of 2 932 papers were included in this study. In the medical field, carbon nanomaterials had a large number of papers and a fast growth rate. The United States has a large number of papers; China is an emerging force in this field, although the number of papers is the largest, but the level of research and influence need to be improved. The Chinese Academy of Sciences is the largest cooperative network institution, which mainly targets domestic institutions and lacks cooperation with well-known foreign institutions. (2) Keyword analysis displays that the green synthesis method and application of displaying carbon points have been the focus of research, followed by the new method of combining carbon nanomaterials with cancer phototherapy and immunotherapy, the key direction of future research. (3) The dynamic development trend of co-citations suggests that tissue engineering is a hot research topic of carbon nanomaterials in the field of biomedicine, mainly including the research of carbon nanomaterials for the repair and regeneration of heart and nerve tissue and as a bio-ink additive for 3D and 4D bioprinting. (4) In the future, with the development of the biomedical field in the direction of precision and treatment, researchers should speed up the creation of carbon-based systems formed by the combination of scientific and effective carbon nanomaterials with science and technology, new polymers or organic molecules, and new therapeutic methods, so as to give full play to the maximum effect of carbon nanomaterials.

To obtain a more comprehensive understanding of the hotspots and research progress of tea beverage at home and abroad, this research paper analyzed the annual publication volume, author co-occurrences, co-citations, research institutions, the number of country publications, journals, and research hotspots of 1247 English literature collected by WOS from 2002 to 2022 using the Web of Science core collection database as the data source and the visual data analysis software CiteSpace v 6.1.6R. The results of the analysis showed that the heat for research on tea beverage at home and abroad continued to rise, and the annual number of publications showed a rising trend year by year. The number of core authors with more than four articles was 584, accounting for 82.4% of the total number of authors. The majority of institutional publications came from Chinese universities, of which the first institution with the highest number of publications was Anhui Agricultural University. The People's Republic of China was the most actively published country, followed by USA and JAPAN. The journals with high publication volume were mainly concentrated in the field of agricultural and food chemistry, and Journal of Agricultural and Food Chemistry was the journal with the highest co-citation frequency, with a total of 988 citations. The "caffeine" "acid" and "catechin" were high-frequency keywords in tea beverage research, with research hotspots focusing on the detection and extraction of active substances in tea beverage, fermented teas, antioxidant and antibacterial activities. In summary, research on tea beverage was still on the rise, but existing studies suffered from a lack of cooperation among authors, limited research areas and convergent research methods, etc. Scholars should strengthen multifaceted cooperation and communication to broaden the breadth and depth of the research, and to jointly promote the development of research in this field. This study provided a reference for a more in-depth understanding of the current status of global tea beverage research in the future.

Sweetpotato is an economically important crop, and it has various advantages over other crops in addressing global food security and climate change. Although substantial articles have been published on the research of various aspects of sweetpotato biology, there are no specific reports to systematically crystallize the research achievements. The current review takes the lead in conducting a keyword-centric spatiotemporal dimensional bibliometric analysis of articles on sweetpotato research using CiteSpace software to comprehensively clarify the development status, research hotspot, and development trend in the past 30 years (1993-2022). Quantitative analysis was carried out on the publishing countries, institutions, disciplines, and scholars to understand the basic status of sweetpotato research; then, visual analysis was conducted on high-frequency keywords, burst keywords, and keyword clustering; the evolution of major research hotspots and the development trend in different periods were summarized. Finally, the three main development stages--preliminary stage (1993-2005), rapid stage (2006-2013), and diversified mature stage (2014-2022)--were reviewed and analyzed in detail. Particularly, the development needs of sweetpotato production in improving breeding efficiency, enhancing stress tolerance, coordinating high yield with high quality and high resistance, and promoting demand were discussed, which will help to comprehensively understand the development dynamics of sweetpotato research fromdifferent aspects of biological exploration.

Purpose: This study aimed to examine the research hotspots and evolution paths in the field of health information behavior (HIB) in China and abroad, and conduct comparative analysis to better understand its development trajectory globally. Design/methodology/approach: A keyword search of the relevant literature included in the China National Knowledge Infrastructure (CNKI) database and Web of Science (WoS) core collection database was conducted, using the visualized analysis tool CiteSpace V for bibliometric analyses. Findings: The common research hotspots in China and abroad can be divided into related research on HIB, research on its influencing factors and health information research. Among these, health information-seeking behavior has been the focus of domestic and foreign scholars. From the subdivision perspective, the focus of Chinese and foreign research hotspots differs. In terms of evolutionary path, the initial stage of HIB research in China and abroad revolves around health information and health information-seeking behavior, followed by the influencing factors of HIB; however, the research breakthrough point is the reverse. Then, domestic and foreign research was conducted on different types of HIBs. Regarding the selection of research objects, Chinese and foreign research objects were increasingly diversified. Research limitations/implications: This study also has several limitations. First, the literature sample only selected the literature in the WoS and CNKI databases, and there may be many HIB-related works published in other databases. Therefore, future research should include other databases. Second, in terms of language, this study selected only Chinese and English literature, but in many countries, important research results on certain topics are usually published in native language, and future research should expand the language selection. Third, this study only conducted national and institutional collaboration network analysis, keyword co-occurrence analysis, cluster analysis and timeline chart analysis. Practical implications: The implication of practice can be divided into the following three points. (1) Analyzing the domestic and foreign literature on HIB and identifying highly cooperative institutions and countries in the field of HIB can reveal the research situation of HIB and help researchers establish new research networks in the future. (2) Analyzing the research hotspots and evolutionary paths of HIB at home and abroad is helpful for quickly understanding the development context of this field and grasping the emerging research directions such as HIB of people in close contact with patients, health information exchange behavior, health information avoidance behavior and health information discontinuation behavior, which can help researchers to explore the future research direction in this field, so as to determine the topic and fill the research gap. (3) Combining the analysis of HIB-related research at home and abroad is helpful for professionals to understand the characteristics and rules of HIB of users, consumers and other groups to further optimize and improve health information services. Originality/value: Comparing and summarizing the research status of HIB in China and globally, and presenting the findings visually, will help researchers better grasp the research overview and hotspot changes in this field, as well as provide a follow-up reference.

The Party Central Committee has placed a high priority on the preservation and transfer of cultural heritage in recent years. To this end, the Committee has released several significant documents, including Opinions on the Implementation of the Project for the Inheritance and Development of Excellent Traditional Chinese Culture, which clearly outline the goals and objectives of the preservation of intangible cultural heritage and are extremely significant both historically and practically. The national intangible cultural heritage list has gradually added many areas of the blue calico printing and dyeing procedures. It is discovered that there is some literature on blue calico, but there are not many in-depth discussions of the topic. The research angle on blue calico is primarily concentrated on its creative design and application, as well as its in a particular area. The term “comprehensive discussion” refers to the fact that all blue calico is included in the summary rather than being restricted to a specific area, and there is a dearth of literature that analyzes the data and text that have been transformed into pictures, graphs, charts, and diagrams from the standpoint of visualization. Therefore, it is very crucial to create a knowledge map and visualization analysis of the blue calico to comprehend the development state, identify research hotspots, and forecast the future development trend of the blue calico. Professor Chen Chaomei of the Drexel University in the United States created CiteSpace, a Java application for information visualization that has been widely used in a variety of fields. Its features include a good visualization effect, a large amount of information provided, simple operation, etc. To analyze the literature in the field of blue calico in terms of publications, authors and collaboration, source journals and institutions, keyword clustering mapping, and bursts, the paper chose journal articles and dissertations from the CNKI database. The paper then used CiteSpace visualization software to analyze the literature and provide a summary of the research content on China’s blue calico over the previous 23 years. Data support for the development of new research directions can be obtained through data visualization and analysis of the existing blue calico research literature from multiple dimensions scientifically and systematically, and understanding the current status and hot trends of blue calico research from a macroscopic point of view. It is discovered that: there are very few complete works on blue calico, and the research varies greatly by location; colleges and universities are the primary sources of literature research institutions, with the majority of them being collaborations between the same institution and department; the design of patterns or motifs, protection and inheritance, and innovation and development are the keywords that are concentrated in these areas; the literature research has undergone three phases: the period of exploration, the period of development, and the period of innovation and inheritance; and improving product design, cultural and creative products, printing, and dyeing direction is going to be a major trend in the future. The legacy of blue calico must adapt to the current circumstances while providing effective protection. Achieving a balance between inventive progress and inheritance requires the integration of current technology and digital communication while maintaining the use of natural raw materials, traditional techniques, and inherited pattern styles.

Background Primary healthcare is the first line of defense for the containment of COVID-19 pandemic. Primary healthcare has been studied extensively by academic circles in various countries during the pandemic, but the focuses vary across these studies due to differences in primary healthcare systems in different countries. Objective To understand the advances, hotspots, trends and differences of primary care-related research at home and abroad during the COVID-19 epidemic, and to provide a reference for further research in this field. Methods Primary healthcare-related studies published during the COVID-19 pandemic (between January 1, 2020 and June 30, 2022) were searched in databases of CNKI and Web of Science Core Collection on July 5, 2022, and 282 from the former database and 1 755 from the latter were included. CiteSpace was used for visualization analysis to provide a graphic visualization of co-occurrence networks of authors, keywords and keywords clusters, to perform a timeline analysis, and to detect keywords with bursts. Results The number of publications in China grew fast at the beginning of the pandemic, then the growth gradually decreased, and tended to level off at the late stage. In contrast, relevant research started later in foreign countries, but the number of relevant publications maintained high-speed growth as of the study time. The major author cooperation forms were inter-small teams cooperation and inter-individual cooperation, and no large-scale inter-team cooperation was found. The hotspots of domestic research focus on the systems, the exploration of mechanisms and management practices related to pandemic prevention and control, while international research focuses on changes in healthcare-seeking patterns and the satisfaction of patients' medical needs under the influence of the pandemic. Psychological problems related to the pandemic were concerned by both domestic and international research. Conclusion Domestic and foreign studies have similarities and different focuses. To continuous refine and diversify domestic research, it is suggested to learn international experience, pay attention to the construction of relevant research forces, improve the knowledge system in this field, and actively use information technology to improve the primary care system amid the pandemic.

In order to analyze the research status and hot trends of water resources ecological footprint, this paper takes CNKI and web of science database as data sources, and uses CiteSpace visual analysis software to comprehensively analyze development status and research hotspots of Chinese and English papers in the field of water resources ecological footprint from 2005 to 2020. The former includes the number of publications, sources of literatures, research institutions, authors, regional cooperation networks and highly cited literatures, while the latter includes keyword cluster analysis and hot emergent word analysis. The development status results show that on the study of ecological footprint of water resources, the Chinese literatures are earlier than the English literatures, and the number of published papers of both show an increasing trend, which are the hot research fields at present. The Chinese and English literatures mainly come from the core journals in the field, mainly involving the environment and ecology and other fields. The cooperative network of Chinese literatures research institutions are relatively decentralized, while the cooperative relationship of English literatures research institutions are closer. There are more researchers in Chinese literatures, forming a relatively obvious cooperative subgroup, while there are fewer English literatures writers and most of them are Chinese scholars. Countries such as China, the United States and the Netherlands are the main forces of literature publication. In the analysis of hotspot emergent words, the intensity of ecological footprint is the highest, indicating that the research of water resources ecological footprint has entered a mature stage. In the future, the depth and breadth of research in the field of water resources ecological footprint should be strengthened to achieve interdisciplinary integration. [ABSTRACT FROM AUTHOR]

With the advancement of digital technologies, digital agriculture improves agricultural efficiency and sustainability, reducing resource waste and environmental burden. Hence, DA has emerged as a new catalyst for grain productivity and a driving force behind climate improvement, with broad prospects. However, digital agriculture is still in its early stage in most countries and there are few systematic reviews. In China, for example, there were only 3 non-core reviews out of 817 literatures on DA. Meanwhile, the use of Citespace is revolutionary as it leverages data visualization to uncover hidden patterns and relationships within literatures, aiding researchers in achieving their objectives. This study aims to address this research gap by using Citespace to produce a non-subjective and testable review on DA. In this study, we collected 2264 literatures by retrieving the WoS database in the timespan 1997-2022. The results show that 1) over time, the annual number of publications on DA has gradually increased and the research can be roughly divided into three stages: start-up, steady development, and rapid development stage; 2) research streams of DA can be further divided into six categories: Remote Sensing, Climate-Smart Agriculture, Artificial Intelligence, Internet of Things, Big Data and System Integration; 3) development of research frontiers could be divided into three parts: “exploration of digital agriculture technologies,” “operation management of digital agriculture” and “limitations of digital agriculture;” 4) future research should pay more attention to the innovation and scientific evaluation of digital technology and operation management. Also, effective DA policies should be put forward to provide a theoretical basis and decision-making reference.

Moreover, data visual analysis was carried out by plotting keyword clustering, time line and burstness maps. It was found that there has been increasing interest in surimi research. The number of surimi research papers indexed in CNKI and WOS has shown an increasing trend in the period from 2009 to 2021, and most papers were published in the top journals in the food field. China has published 441 research papers in English, ranking first in the world, accounting for 37.99% of the world’s total, followed by Thailand, the United States and Japan. The close cooperation between authors and research institutions in different regions and countries has formed an international academic community. The research content has shifted from the macroscopic field to the microscopic field, and the research hotspots have changed from processing technology and surimi quality to preservation and antifreezers. At present, “protein” “myosin” and “secondary structure” have become new keywords and the research content has reached the molecular level. The time zone analysis showed that the keywords “sensory evaluation” and “quality” span the entire research period and have become the cornerstones of surimi research. In conclusion, surimi research is still in an active stage and will have a bright future.

Xi Jinping Thoughts on Socialism with Chinese Characteristics for a New Era has been a hot spot and frontier issue in academic research in recent years. This study adopted the bibliometric software CiteSpace to visually analyze 1 074 documents included in Chinese Social Sciences Citation Index (CSSCI) source journals since the 19th National Congress of the Communist Party of China. The study found that the research hotspots mainly focus on the generation, meaning, philosophical implication and theoretical arming of the new ideas, with the characteristics of obvious problem orientation, detailed thematic perspective and in ⁃ depth practical research. Standing at the starting point of a new journey, it is necessary to expand the scope of the research further, respond to practical concerns, innovate research methods, and broaden international perspectives to provide a reference for future research.

The CiteSpace bibliometric software was used to quantitatively analyze the research papers on green railways retrieved from the China National Knowledge Infrastructure (CNKI) database during 1985–2021. Combined with content association analysis, the development stages, frontier hotspots, and evolutionary trends of green railway research in China were summarized in the Chinese context. The results show that in the past 36 years, China's green railway research has experienced four main stages: the emerging stage (1985–1997), the horizontal expansion stage (1998–2010), the vertical deepening stage (2010–2015), and integrated expansion stage (2016–present). The research topics emerging in the four stages are green design and green construction, green channel and green logistics, energy conservation and emission reduction and green evaluation, multimodal transportation, and green development. In general, the research topics are diversified, but green construction of railway infrastructures and green manufacturing of railway equipment have been the research hotspots all the time. Both external and internal paths drive the transmutation of academic frontiers, and the push effect of the external path is more evident than the internal path. Interdisciplinary integration and innovation gradually become a new force to promote green railway research. As the railway development slowly enters a "big operation era", it can be inferred that the development trend of green railway research could throw light on the following three areas: from the research perspective and topics, it should be based on a framework of life cycle management to explore, systematically and deeply, the correlation and integration of railway green design, green construction, green operation and maintenance; in terms of the research content, more focus should be on new theories, new methods, and new technologies of railway green operation and green maintenance on the basis of railway green design, construction, and manufacturing research, such as railway green operation strategies and evaluation systems and green transportation organization theories and methods; from innovation paths, academic progress still needs both external and internal paths, interdisciplinary integration and innovation as the primary internal driving force to promote green railway research, and more focus on the use of big data and artificial intelligence and other technologies to innovate green railway development.

Carbon emissions are critical to climate change, and land-use change is an essential source of growth in carbon emissions. Research on land-use carbon emissions has become one of the hotspots in academic research. To explore the research hotspots and development trends of land-use carbon emissions in the last 20 years, CiteSpace software was used to conduct a quantitative analysis of relevant literature. This paper was based on the China National Knowledge Infrastructure (CNKI) and Web of Science (WoS) database literature on land-use carbon emissions from 2001 to 2020. The scientific research cooperation network CiteSpace software, with keyword co-occurrence, clustering, and burst word detection, was used to systematically analyze the main research strengths, hotspots and frontiers and clarify the research progress. The research results are as follows: (1) the amount of literature and the depth of research on land-use carbon emissions have increased yearly. However, there is little cooperation between research institutions and scholars, and there is still a lack of large-scale and stable research teams. (2) At the research hotspot level, the English literature focuses on building models and theoretical frameworks to study the internal mechanisms and driving factors of carbon emissions and climate change. The Chinese literature focuses on achieving regional carbon emissions reductions and carbon cycle goals and optimizing a low-carbon economy, transportation and land-use structure. (3) Research frontiers and trends show that the English literature first explored carbon sequestration, organic carbon, and carbon accounting. In China, the research frontiers are gradually becoming focused on influencing factors, decoupling analysis, and the built environment. The study will strengthen the intensity and depth of global carbon emission research and provide a reference for improving global climate change, protecting ecology and balancing economic development.

OBJECTIVE: To explore the research status, hotspots and trends of rehabilitation therapy in anterior cruciate ligament reconstruction in the past 11 years based on the scientific knowledge mapping using the CiteSpace software, attempting to provide ideas and reference for the subsequent research and clinical treatment of anterior cruciate ligament reconstruction. METHODS: The Web of Science (SCI-Expanded, SSCI, CCR-Expanded, IC) core collection database was retrieved for the literature related to rehabilitation treatment and anterior cruciate ligament reconstruction published from 2010 to 2020. Scientific knowledge mapping and visualization analysis using CiteSpace were subsequently conducted. RESULTS AND CONCLUSION: A total of 323 papers were included, and the number of published papers and total citation frequency in this field increased steadily in the past 11 years. A total of 101 journals have published articles related to this field. The research fields of the included journals are concentrated in sports science, rehabilitation, plastic surgery, and surgery, KNEE SURGERY SPORTS TRAUMATOLOGY ARTHROSCOPY is the journal that has the most publications. The top three countries with the most publications are the United States, Italy, and China, and the top three institutions with the most publications are Univ Delaware, Ohio State Univ, and Univ Groningen. Univ Delaware in the United States tops the list in terms of article amount and centrality. The team led by Lynn Snydermackler, a professor from the Department of Physical Therapy at the Univ Delaware, that has the most articles published in this field has a greater influence in this field. Literature co-citation analysis indicates the topics involved in the top five literatures include the timing of returning to sport level, evaluation indexes, knee joint function status and influencing factors, rehabilitation practice guidelines based on multidisciplinary consensus, risk rate of secondary injury after anterior cruciate ligament reconstruction and related interventions. Keywords analysis indicates that research on rehabilitation training plan, return to sport and secondary injury after anterior cruciate ligament reconstruction is a hot topic in this field. All these findings reveal that relevant research on rehabilitation training after anterior cruciate ligament reconstruction has been on the rise in recent 11 years. The focus in this field has been gradually shifted from local function of the knee joint to individual social participation. The research direction has gradually developed from the initial discussion of specific rehabilitation methods to guiding return to sport and avoiding secondary injury. Development of standards/guidelines for safe return to sport will be a future trend in this field. [ABSTRACT FROM AUTHOR]

Heavy metals pollution in soils is an urgent environmental issue worldwide. Phytoremediation is a green and eco-friendly way of remediating heavy metals. However, a systematic overview of this field is limited, and little is known about future development trends. Therefore, we used CiteSpace software to conduct bibliometric and visual analyses of published literature in the field of phytoremediation of heavy metals in soils from the Web of Science core collection and identified research hotspots and development trends in this field. Researchers are paying increased attention to phytoremediation of heavy metals in soils, especially environmental researchers. A total of 121 countries or regions, 3790 institutions, 4091 funded organisations and 15,482 authors have participated in research in this area. China, India, and Pakistan are the largest contributors. There has been extensive cooperation between countries, institutions, and authors worldwide, but there is a lack of cooperation among top authors. 'Calcareous soil', 'Co-contaminated soil' and 'Metal availability' are the most intensively investigated topics. 'EDTA', 'Plant growth-promoting Rhizobacteria', 'Photosynthesis', 'Biochar' and 'Phytoextraction' are research hotspots in this field. In addition, more and more researchers are beginning to pay attention to research on co-contaminated soil, metal availability, chelating agents, and microbial-assisted phytoremediation. In summary, bibliometric, and visual analyses in the field of phytoremediation of heavy metals in soils identifies probable directions for future research and provides a resource through which to better understand this rapidly advancing subject. [Display omitted] • Research progress on the phytoremediation of heavy metal in soils was reviewed. • This article explores the countries, institutions and authors that play a leading role. • This article explores the main research hotspots in this field. • This paper explores the opportunities and challenges for this research. • The results provide a valuable reference for follow-up research.

Taking China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) journal database as data sources, the annual publication volume of the research literature, author-institution cooperation distribution, research hotspots, and evolution trends from the domestic and foreign research literature on module division from 2000 to 2019 were visually analyzed with the CiteSpace software to draw scientific knowledge graph. It was pointed out that the research in the field of module division was paid close attention by seniors at home and abroad, and it experienced the following three stages: the initial exploration period (2000-2008), the rapid growth period (2009-2015), and the steady development period (2016-2019). From the perspective of the distribution of core authors and research institutions, it was found that China and the United States had the most outstanding research results in the field of module division. It indicated that China had become the backbone of this field in the international stage and the developed countries such as the United States were still the main research groups. The domestic and foreign research focused on the product's green module division, product design, mass customization, etc. However, foreign researches focused on the multi-disciplinary field, such as complex network, multi-objective optimization and biological network modularity. The domestic researches focused on theoretical methods of the module division with a narrow application scope. The future research will be conducted on key words such as national gene network, dynamic analysis, digital twin, etc. Among them, solving the organization and layout of the complex product's life cycle modules as well as applying digital twins to grasp the granularity of product function modules will be the focus and direction for the future research.
