A bibliometric analysis of world volatile organic compounds research trends

Abstract

This study explores a bibliometric approach to quantitatively assessing current research trends on volatile organic compounds, by using the related literature in the Science Citation Index (SCI) database from 1992 to 2007. The articles acquired from such literature were concentrated on the general analysis by scientific output, the research performances by countries, institutes, and collaborations, and the research trends by the frequency of author keywords, words in title, words in abstract, and keywords plus. Over the past years, there had been a notable growth trend in publication outputs, along with more participation and collaboration of countries and institutes. Research collaborative papers had shifted from the national inter-institutional to the international collaboration. Benzene, toluene, and formaldehyde were the three kinds of VOCs concerned mostly. Detection and removing, especially by adsorption and oxidation, of VOCs were to be the orientation of all VOCs research in the next few years.

A Bibliometric Analysis of Linguistics Publications in the Web of Science

“…[24,35] Distribution of title words, words in abstract, authors' keywords, and Key Words Plus over different periods of time have been thoroughly examined to elucidate research focus. [36,37] Key Words Plus in the Web of Science database supplied additional search terms extracted from the titles of articles cited by authors in their bibliographies and footnotes. [38] Word clusters has been further applied to determine the research foci and to characterize article lives in subsequent years.…”

Research trends in electrochemical technology for water and wastewater treatment

“…Both ''carbon'' (2075; 7.9 %) and ''cell(s)'' (1846; 7.0 %) related to electrode(s) had an apparent upward progress in their ranks, from 21st and 40th in -1998to 4th and 5th in 2009 '', ''oxide'', ''treatment'', ''modified'', and ''nanotube(s)'' showed a continuous increasing trend in titles, while the terms ''solution(s)'' showed a decreasing trend. It is worth mentioning that ''Nanotube(s)'' had a notable promotion, the same with ''carbon nanotube(s)'' in author keywords, which did not appear in 1994-1998, but ranked 15th in 2009-2013. Distribution of words in article abstracts of different periods could also be the information of research trend analysis (Zhang et al 2010a;Fu et al 2014). In the analysis of article abstracts in current study, the words in article abstracts showed that ''electrochemical'', ''electrode(s) TP articles in the study period, R (%) the rank and percentage of the author keywords Appl Water Sci (2017) 7:13-30 23 ''process'', ''hydrogen'', ''acid'', ''oxygen'', ''cyclic'', ''properties'', ''aqueous'', and ''pH'' appeared at least 4,000 times.…”

“…Science Citation Index Expanded TM , accessed via Web of Science TM Core Collection, was the most important and frequently used source database for an overview of scientific production. Bibliometric methods have been widely applied to assess the scientific outputs of various fields, especially on environmental concerns and energy utilization frontier, such as drinking water (Hu et al 2010), nitrate removal (Huang et al 2012), sediment (Niu et al 2014), solid waste (Fu et al 2010), volatile organic compounds (Zhang et al 2010a), and materials of lithiumbased batteries (Wagner et al 2013). In addition, research patterns including journals, categories, countries, and institutes, as well as the international cooperation had been broadly applied (Fu et al 2010Niu et al 2014;Tan et al 2014).…”

Bibliometric Analysis of Research on Secondary Organic Aerosols: A Science Citation Index Expanded- Based Analysis (IUPAC Technical Report)

“…Bibliometric methods concerning author keywords have only been used in recent years [20], and their use in analyzing research trends is rare [11,13,14,16]. In 1707 publications from 1992 to 2011, 599 (35.1 %) had author keywords.…”

“…A common research tool for this analysis is the bibliometric method. The Science Citation Index Expanded (SCI-EXPANDED) from the Institute of Scientific Information (ISI) Web of Science databases is the most important and frequently used source for a broad review of scientific accomplishment in all fields [11,[13][14][15][16].…”
