Background: Enteroviruses-infected hand, foot, and mouth disease (HFMD) seriously threatens human health. This study aimed to analyze the research status, hotspots, and frontiers of HFMD. Methods: Publications on HFMD between January 1, 2006, and January 31, 2023, were retrieved from the Web of Science Core database. Bibliometric tools, including CiteSpace, VOSviewer, R package “Bibiometrix,” SCImago Graphica, and Charticulator, were utilized to analyze and visualize the data. Results: A total of 1860 articles from 424 journals, involving 8815 authors from 64 countries and 1797 institutions were analyzed. The number of studies on HFMD has shown an increasing trend over the past 18 years, with an annual increase observed since 2006, which is particularly prominent after 2010. Research in this field has centered on the Asian region. Notably, the research hotspots were mainly focused on vaccines, epidemiology, and pathogenesis of HFMD. Among the researchers in this field, Zhang Yong emerged as the most prolific author, while Xu Wenbo had the most significant influence. The Chinese Academy of Sciences was the most productive institution, and China was the most productive country for HFMD research. Conclusion: By bibliometric analysis, researchers in the HMFD field can efficiently identify and visually represent their research focus and limitations. In the future, it is crucial to maintain ongoing surveillance of HFMD outbreaks and their pathogenic changes. Additionally, future research should extensively explore the molecular mechanisms underlying Enteroviruses-induced HFMD with a focus on developing vaccines and therapies.

This study examines the pyrolysis of agricultural residues, namely, coconut shells, rice husks, and cattle manure, in a vertical fixed-bed reactor at varying temperatures from 300 to 800 degrees Celsius for biochar production. The research aimed to evaluate the potential of biochar as biofuels, adsorbents, and soil amendments. Proximate, ultimate, and elemental analyses were conducted to determine their composition and caloric values. Several analytical techniques were used in the physical and chemical characterization of the biochar (SEM, FTIR, BET). The results indicated that the highest SBET values were achieved under different conditions for each biochar: 89.58 m2/g for BC-CS-700, 202.39 m2/g for BC-RH-600, and 42.45 m2/g for BC-CD-800. Additionally, all three biochars exhibited the highest caloric values at 600 °C. The results showed that 600 °C is the general optimal temperature to produce biochar from an assortment of biomass materials, considering their use for a variety of purposes. BC-CS-800 had the highest elemental carbon content at 93%, accompanied by a relative decrease in oxygen content. The van Krevelen diagram of biochar products shows that biochars derived from coconut shells and rice husks are suitable for use as fuels. Furthermore, FTIR analysis revealed the presence of oxygen-containing functional groups on the biochar surface, enhancing their pollutant adsorption capabilities. This study provides valuable insights into the scalable and environmentally sustainable production of biochar, emphasizing its role in improving soil quality, increasing energy density, and supporting sustainable agricultural practices.

“…Biochar, which is an abbreviation of Bio and Charcoal [1], refers to a class of insoluble, stable, and highly aromatic carbon-containing substances synthesized by thermal treatment of biomass wastes under oxygen-limited conditions [2], which have numerous advantages, such as high adsorption capacity, carbon stability, and the ability to embed minerals and trace elements [3,4]. Biochar has been discovered to have various applications, including improving soil, fertilizing soil, environmental remediation, and producing bioenergy [5][6][7], which accomplishes resource reuse and waste reduction [8]. Biochar can also be a carbon sink to slow the greenhouse effect [9].…”

“…In addition, the pyrolysis conditions of biochar and its physicochemical characteristics, among others, can adsorb and trap greenhouse gases like carbon dioxide and methane [14,15]. Biochar can be obtained from a wide range of feedstock sources, such as plant, animal, and municipal waste [6,16], and in particular, the conversion of sludge to biochar offers another promising approach to managing waste biomass [17]. Biomass can be heated and treated using pyrolysis and gasification techniques to produce clean energy products such as syngas, biochar, and biooil [18].…”

“…Bibliometric techniques are widely applied in commerce, management, medicine, and agronomy [37,[39][40][41]. In recent years, bibliometrics has also dealt with research on a variety of biochar-related topics, including the application of biochar in environmental management [7], the current state of biochar research and its development trend [6,[42][43][44], the remediation of contaminated soils with biochar [45][46][47][48], the application of biochar in agriculture [49,50], the preparation of biochar [51], and the impact of biochar in soil and its applications [52,53]. To the best of our knowledge, few bibliometric studies are available on ABFS.…”

Considering the impacts of global climate change, paths for sustainable development are of particular importance. Biochar has multiple advantages, including but not limited to climate change mitigation, waste management, soil fertility improvement, and pollution remediation. Forest soils play a significant role in terrestrial ecosystems. The application of biochar in forest soils (ABFS) is therefore considered an essential tool for improving soil quality, capturing carbon, and reducing greenhouse gas emissions. The Web of Science Core Collection database was utilized for the bibliometric analysis of ABFS publications published between 2002 and 2022. Three bibliometric software were used to analyze bibliometrics, networks, and research directions for ABFS: Bibliometrix, VOSviewer, and CiteSpace. The analysis shows that research on ABFS is always rapidly developing. Research on ABFS is engaged globally in a complex network of collaborations, and the main research has occurred in China and the United States. Collaboration among authors is relatively diffuse. Research on ABFS involves interdisciplinary integration. In the early stages of research, the origin of biochar (history and boreal forests) and its characteristics (dynamics, nitrogen content, and chemical composition) were the focus of attention. As research progressed, more attention was given to ABFS (carbon, organic matter, vegetation, and heavy metals). Our research shows that while ABFS research has a certain history, its development trend has been consistently upward and shows no signs of declining. Thus, future research will likely concentrate on ABFS. Due to the complexity of biochar functions, ample research opportunities exist in ABFS.
