Technological Indicators of Nanocellulose Advances Obtained from Data and

Nanocellulose is remarkable cellulose-based nanomaterials that have a potential for
innovation and sustainable appeal. Their advances can be assessed using patent indicators and text  mining techniques. The aim of this study was at analyzing the advances in nanocellulose based on  indicators compiled from patents filed at the United States Patent and Trademark Office (USPTO)  from 2000 to 2012. Assignees, technological subjects, highly cited patents, applications and types of  nanocellulose were obtained by mining structured and unstructured data. The results highlighted the  different interests in the USA market, mainly after 2007. Mined terms from titles and abstracts could  add further information to the analysis. However, although the method applied was useful, it was not
sufficient to identify all applications and types of nanocellulose involved in the sample analyzed, therefore it is recommended that other document parts be included in future analyses.

Why do technology firms publish scientific papers? The strategic use of science by small and midsize enterprises in nanotechnology

In the emerging technology domain of nanotechnology, a significant portion of small and midsize enterprises contribute to the scientific literature by publishing their research and development results. However, while considerable attention has been paid to patenting by small and midsize technology firms, the underlying business motivations for such firms to publish scientific papers are not well understood. This paper investigates the scientific publishing patterns of smaller firms engaged in nanotechnology and the factors that underlie this phenomenon. Based on an analysis of 85 US small and midsize enterprises with a minimum of four nanotechnology patents or publications, we test three hypotheses about corporate publishing: reputational gains, absorptive capacity, and strategic spillovers. We find that the small and midsize firms in our sample are more likely to publish when their work is associated with public science and when it involves a greater technological focus, but having a university collaborator is not a significant factor. The results from this study of nanotechnology enterprises suggest that small and midsize technology firms selectively manage and disclose their research based on internal developmental and capacity drivers.

Nanotechnology Research and Innovation in Russia: A Bibliometric Analysis

This working paper presents findings from analyses of Russian nanotechnology outputs in publications and patents focusing on developments over the period 1990 through to 2012. The  investigation draws on bibliometric datasets of scientific journal publications and patents and on available secondary English-language and Russian sources. The document provides both an overview and detailed analyses of nanotechnology research and innovation in Russia. The examination of publications highlights sectoral trends, leading authors and organizations, and acknowledgements to funding sources. The analysis of patents adds further evidence about patterns of invention and ownership of intellectual property emanating from research and development in Russian nanotechnology. The analyses in this paper have been undertaken to provide an information base for further research on the current state and trajectory of nanotechnology in Russia and on the broader development of Russia’s innovation system. Comparisons with Chinese publication and patent outputs can be seen in a parallel report on Nanotechnology Research and Innovation in China (2014).

International comparative study on nanofiltration membrane technology based on relevant publications and patents

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.

Development of carbon-based nanomaterials indicators using the analytical tools and data provided by the web of science database

The recent rise of nanotechnology and nanomaterial research is marked by the huge amount of publications indexed in electronic databases, which can be evaluated using bibliometric indicators in order to help researchers find hidden trends, gain novel insights and support new scientific developments. Although in-depth analyses require specialized software and advanced methodologies, some initial indicators can be developed using the analytical tools available in databases and provide useful information about a specific subject or research field. This paper aims to explore the Web of Science’s analytical tool for analyzing the scientific output regarding carbon-based nanomaterials. The results provide several key findings, including research trends and publications in carbon nanotubes, fullerene and graphene, as well as revealing the main global players and journals from 2001 to 2010. Despite the usefulness of the analytical tool, a number of limitations hindered the development of important indicators, such as those involving citation and collaboration.

Portrait of China’s R&D Activities in Nano-Science and Nanotechnology in Bibliometric Study

China has made great improvement in some critical scientific subject, like nanoscience and nanotechnology. This study explores the state-of-the-art developments of China in nanoscience and nanotechnology, as the previous study showed that China has become the second leading nation in terms of its share of “nano-prefixed” publications all over the world. Patent applications are also included in this study, as there are considerable efforts underway that aim to commercialise nanotechnology, and it is also an important aspect of R&D output. In particular, this study compares the rising pattern of nano-publication and nano-patents, to showcase the gap which lies between the knowledge base and technology base. Furthermore, this study investigates the research focus for both publications and patents in nanoscience and nanotechnology. The findings suggest that the strong presence of publications in MATERIALS SCIENCE, PHYSICAL CHEMISTRY and APPLIED PHYSICS are also in line with China’s overall research focus; while there are also many inventions focused on novel formulations of pharmaceutical products which have recently applied in Chinese Traditional Medicine. Finally, the cross-analysis of top organizations and Derwent Classification indicates that the collaboration links between organizations are relatively weak, though their technologies are highly concentrated in some similar areas. Collaborative research is a double edged-sword which may either mutually enhance the research base, or damage to the competitive advantage in commercialization.
