This study adopts a bibliometric approach to quantitatively assess current research trends in nanofiltration membrane technology (NFM), a new membrane separation technology widely used in various fields. It analyses scientific papers published between 1988–2011 in all journals contained in the Science Citation Index and patent data with the same time span from the Derwent patent database. The study examines developments in basic NFM research and technological innovations. Over the past 24 years, there has been a notable growth in publication outputs. Compared with other countries, China exhibited a rapid growth, particularly from 2000–2011, with its total number of papers ranking second only to the United States (US). Chinese NFM papers focus on energy and agriculture, while the US focuses on biochemistry and molecular biology. China holds the most global NFM patents, with rapid growth in patent numbers from 2005–2011. China, the US and Japan together hold 78 % of the total global NFM patents and have a strong technological advantage in water treatment and separation technology. Although there are four Chinese institutions in the top 10 patentee list, most are application patents that focus on the integrated application of existing nanofiltration membrane. In contrast the patents owned by foreign patentees are mostly research patents involving technology innovations of the nanofiltration membrane itself. Therefore, NFM research capacity in China should be further strengthened to maximize the advantages gained via research to date.

China’s rise in science has been widely acknowledged. Yet we know little empirically about academic research focusing on China. Utilizing a uniquely constructed large-scale dataset, this paper explores China-related publications through bibliometric analysis. Our data suggests that not only interest in China but also knowledge about China has developed rapidly over the years. Despite an increasingly diverse profile of participants, the substantial rise of research focusing on China is largely limited to affluent regions and some geographically proximate neighbors of China. The research discloses that overseas Chinese facilitate academic research focusing on China. The research foci of China-related studies have gradually shifted from social science to natural science and, in more recent years, to Chinese environmental issues, public health and economy.

In recent years, many epidemiological and toxicological studies have investigated the adverse effects of air particulate matter (PM) on the cardiovascular system. However, it is difficult for the researchers to have a timely and effective overall command of the latest characteristics and popular topics in such a wide field. Continue reading Characteristics and popular topics of latest research into the effects of air particulate matter on cardiovascular system by bibliometric analysis
Artemisinin was first extracted from the herb Artemisia annua which has been used for many centuries in Chinese traditional medicine as a treatment for fever and malaria. It has been given the 2011 Lasker-DeBakey clinical medical research award. In this paper, knowledge map of artemisinin research was drawn to provide some information for global researchers interested in artemisinin and its relevant references.

In recent decades, the root exudates and applied research in ecology has made significant progress. In particular, more and more attentions were paid to the role and functions of the root exudates of forest vegetation in ecological restoration and reconstruction process. Using the databases of SCIE, CPCIS, CCR, and IC as the sources, we retrieved and analyzed the articles on the root exudates (including original articles, conference abstracts and proceedings, as well as reviews). Continue reading Trends of the International Plant Root Exudates Studies based on Bibliometrical Analysis
Nanoscience and nanotechnology––involving the engineering of materials, devices, and systems at very small scales––have emerged as important priorities not only for science but also for economic development. Continue reading Engineering Small Worlds in a Big Society: Assessing the Early Impacts of Nanotechnology in China
Medical and health care applications of nanotechnology have increasingly attracted research and innovation attention. Nano-biomedical science (NBMS) is a term we use to define this emerging domain. Continue reading Nanobiomedical science in China: a research field on the rise
Nanotechnology research has emerged as a monumental scientific endeavor worldwide. Over the past decade, China’s nanotechnology publication activity has grown exponentially at an annual rate of about 20%. International collaboration plays a major role in this Chinese research advance. This paper explores these nanotechnology collaboration patterns and collaborators’ performance through bibliometric and text mining analyses to draw policy implications for promoting further research.

Recent studies have consistently reported that China is becoming a leading nation in scientific output, notably in the emerging field of nanotechnology. Given the existence of Chinese diaspora and reverse migration, the driver of such growth is presumed to be international collaboration. However, little evidence shows collaboration to be the principal determinant. The purpose of this article is to examine the impact of international collaboration on the research visibility of China nanotechnology.
