To gain insight into the trend of bacterial nanocellulose research, a bibliometric analysis was performed using the Science Citation Index Expanded database from 2005 to 2020. The study concentrated on the publication’s performance in terms of annual outputs and citations, mainstream journals, categories of the Web of Sciences, leading countries, prominent institutions, and trends in research. Current research priorities and future trends were analyzed after summarizing the most commonly used keywords extracted from words in the paper title analysis, authors’ keyword analysis, and KeyWords Plus. The findings revealed that the annual output in the form of scholarly articles on bacterial nanocellulose research steadily increased during the first quartile of the study period, followed by a very rapid increase in the last five-years of the study. Increasing mechanical strength would remain the main future focus of bacterial nanocellulose research to create its scope in different field o...

Editorial materials express the opinions of the scientific community and guides the publication foci; thus, providing insight into the dynamics of the knowledge ecosystem in a scenario that impacts innovation and public policies. The purpose of this bibliometric analysis was to identify the main characteristics of the editorial materials published at the beginning stage of the COVID-19 pandemic, published between 2019 and April 30, 2020 and indexed in the Web of Science Core Collection. A total of 537 editorial materials were written by 1,455 authors, primarily in English, and in the general and internal medicine category. The majority of these editorial materials were published in the British Medical Journal and Lancet. The United States, China, and United Kingdom had the most editorial materials, with Harvard Medical School, Imperial College, and Oxford University were the leading universities. Richard Horton was the most prolific author and the editorial material by Hui et al. (2...

A comparison of the kinetics of the sorption of copper(II) on to peat from aqueous solution at various initial copper(II) concentrations and peat doses was made. The Elovich model and the pseudo-second order model both provided a high degree of correlation with the experimental data for most of the sorption process. There was a small discrepancy at the initial stages of sorption which suggested that film diffusion or wetting of the peat may be involved in the early part of the sorption process. Models evaluated included the fractional power equation, the Elovich equation, the pseudo-first order equation and the pseudo-second order equation. The kinetics of sorption were followed based on the sorption capacity of copper(II) on peat at various time intervals. Results show that chemical sorption processes may be rate-limiting in the sorption of copper(II) on to peat during agitated batch contact time experiments. The rate constant, the equilibrium sorption capacity and the initial sorp...

Chuang, K. Y., Wang, M. H., & Ho, Y. S. (2013). High-impact papers published in journals listed in the field of chemical engineering. Malaysian Journal of Library & Information Science, Vol.18, no. 2: 47-63. The Essential Science Indicators (ESI) database of Thomson Reuters is widely used to evaluate and identify important, high-impact papers, but few researches have looked at attributes of the ESI database. Using the category of “chemical engineering” as an example, characteristics of the ESI database were described, and distributions of document type, language of the paper, and journal of publication were reported. Five indicators, total number of papers, first-author papers, corresponding-author papers, independent papers, and collaborative papers, were applied to evaluate publications by country, institution, and author. In addition, the number of authors cited, number of institutions cited, number of countries cited, number of subject areas cited, and number of journals cited w...

The machine learning (ML) paradigm has gained much popularity today. Its algorithmic models are employed in every field, such as natural language processing, pattern recognition, object detection, image recognition, earth observation and many other research areas. In fact, machine learning technologies and their inevitable impact suffice in many technological transformation agendas currently being propagated by many nations, for which the already yielded benefits are outstanding. From a regional perspective, several studies have shown that machine learning technology can help address some of Africa’s most pervasive problems, such as poverty alleviation, improving education, delivering quality healthcare services, and addressing sustainability challenges like food security and climate change. In this state-of-the-art paper, a critical bibliometric analysis study is conducted, coupled with an extensive literature survey on recent developments and associated applications in machine lea...

Background An adequate response to health needs to include the identification of research patterns about the large number of people living in the tropics and subjected to tropical diseases. Studies have shown that research does not always match the real needs of those populations, and that citation reflects mostly the amount of money behind particular publications. Here we test the hypothesis that research from richer institutions is published in better-indexed journals, and thus has greater citation rates. Methods The data in this study were extracted from the Science Citation Index Expanded database; the 2020 journal Impact Factor (IF2020) was updated to 30 June 2021. We considered places, subjects, institutions and journals. Results We identified 1041 highly cited articles with ≥100 citations in the category of tropical medicine. About a decade is needed for an article to reach peak citation. Only two COVID-19–related articles were highly cited in the last 3 y. The most cited art...

Li et al. (2019) recently published a paper in the journal, entitled “Dynamic analysis of international green behavior from the perspective of the mapping knowledge domain.” Many of the related results presented in the original paper (Li et al. 2019) are not acceptable because of the use of inappropriate search methods. Li et al. stated in Data sources that “Two databases, SCI-EXPANDED and SSCI, were selected from the core collection of Web of Science. With the topic ‘green behaviour,’ 23,352 documents published from 1986 to 2017 were obtained, including papers, abstracts, and reviews. To make the analysis more scientific, it was necessary to re-screen the 23,352 records and refine them in the literature. Finally, 22,114 papers published from 2000 to 2017 were obtained and exported in the form of full records (covering author and author units, source journal titles, titles, keywords, and abstracts) and cited references in plain-text format.” SCI-EXPANDED and SSCI from 1986 to 2017 were selected as mentioned in the original paper (Li et al. 2019). In total, 26,605 and 25 documents were found by using searching keywords (green behaviour) and (“green behaviour”) respectively. After our pre-study, searching keywords “green behaviour,” green behaviours,” green behavioural,” “green behavior,” “green behaviors,” and “green behavioral” should be considered for “Dynamic analysis of international green behavior from the perspective of the mapping knowledge domain.” This method results 95 documents including 93 articles in which 86 articles (92% of 93 articles) had searching keywords in their “front page” while seven articles (7.5%) did not include searching keywords in their “front page.” For example, articles entitled “Improving environmental performance through unit-level organizational citizenship behaviors for the environment: A capability perspective” (Alt and Spitzeck 2016) and “Investigating willingness to save energy and communication about energy use in the American workplace with the attitude-behavior-context model” (Xu et al. 2017). By using the “front page” as a filter, it will avoid introducing unrelated articles for analysis (Fu et al. 2012; Ho 2018c). In recent years, similar rebuttals have also been published in Environmental Science and Pollution Research (Ho 2018a), Renewable & Sustainable Energy Reviews (Ho 2018c), and Journal of Soils and Sediments (Ho 2019). The Web of Science Core Collection is designed for researchers to find published literatures, not for bibliometric studies (Ho 2018a, b). Therefore, it is critical for researchers to use Web of Science Core Collection accurately (Ho 2018a, b). It was pointed out that the documents searched out by

As a result of the COVID-19 pandemic and the major challenges generated in education, thousands of scientific papers have been published, contributing to the establishment of a distinct research line in the field. This study provides a bibliometric overview of the educational publications linked to COVID-19 indexed by the Web of Science Core Collection for the years 2020 and 2021. The findings show a growing interest of researchers in education in this area. The proportion of articles among the types of documents proved to be dominant. Journals dedicated to chemistry and medical education stood out for the high number of pandemic-related papers. Higher education has been an intensively explored area during the pandemic. The USA and its universities were the most productive in publishing studies on COVID-19 in education. Our study indicated research themes that have been explored by the researchers, such as online learning in different educational settings, curriculum and instruction...

We presented a bibliometric analysis of publications on global scientific and technological research in the field of fuel cell based on the data from Science Citation Index Expanded, Web of Science from 1992 to 2011, to provide insights into the characteristics, research activities and technological breakthrough and identify patterns and tendencies. Articles were assessed by many aspects, including model regression fitting the trend of publication outputs, distribution of words in source title, author keyword and KeyWords Plus. By synthetically analysing the keywords, it can be inferred that application of fuel cell ranges from automobiles to consumer electronic devices. Research especially related to ‘proton exchange membrane fuel cell’, ‘direct methanol fuel cell’, ‘molten carbonate fuel cell’, ‘solid oxide fuel cell’ and ‘catalysts’ is the orientation of the fuel cell research in the twenty-first century.
