This research aims to examine scientific and technological trends of developments in nanocellulose based on scientometric and patent indicators obtained from the Science Citation Index and Derwent Innovations Index in 2001-2010. The overall nanocellulose activity indicators were compared to nanotechnology and other selected nanomaterials. Scientific and technological future developments in nanocellulose were forecasted using extrapolation growth curves and the main countries were also mapped. The results showed that nanocellulose publications and patent documents have increased rapidly over the last five years with an average growth rate higher than that of nanotechnology and fullerene. The USA, Japan, France, Sweden and Finland all played a significant role in nanocellulose development and the extrapolation growth curves suggested that nanocellulose scientific and technological activities are still emerging. Finally, the evidence from this study recommends monitoring nanocellulose S&T advances in the coming years.

In this study, we evaluated future trends of worldwide patenting in nanotechnology and its domains using logistic growth curves while the patent activity from the main countries, technological domains and subdomains were assessed in four different contexts: worldwide, patents filed in the United States Patent and Trademark Office (USPTO), and patents applications in the triadic (TRIAD) and in the tetradic (TETRAD) countries. The indicators were developed based on a set of records recovered from the Derwent Innovation Index database. Nanotechnology has recently emerged as a new research field, with logistic trend behaviors generating interesting discussions since they suggest that technological development in nanotechnology and its domains has reached an initial maturation stage. Future scenarios were compiled due to the difficult to establish upper limits to forecasting curves. Although China’s share of patents is small in some cases, it was the only country to constantly increase the number of patents from a worldwide perspective. In contrast, the USA and the EU were the most active in the USPTO, TRIAD and TETRAD cases, followed by Japan and Korea. The technological subdomains of main interest from countries/region changed according to the perspective adopted, even though there was a clear bias towards semiconductors, surface treatments, electrical components, macromolecular chemistry, materials–metallurgy, pharmacy–cosmetics and analysis–measurement–control subdomains. We conclude that monitoring nanotechnology advances should be constantly reviewed in order to confirm the evidence observed and forecasted.

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.

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.

This study proposes a methodological guide to explore and select materials for executive aircraft interiors, contributing toward a perspective of materials requirements, indicators and strategies to design more environmentally sustainable products. This was motivated by the signs from the aviation industry to reduce its environmental impact and the permanent need to push for cost efficiency. The guide includes a schedule framework of materials requirements for sustainable design, and also aeronautical materials and marketing requirements. It was prepared by mapping sustainability demands for materials selection during product development, supported by a case study. Patented eco-friendly materials solutions for the case study involving the aircraft furniture structural panels were described and analyzed, considering the materials requirements of the aeronautical project. Composites of bio-polymers reinforced with natural fibers, preferably with solid cores, seem to be the most promising solutions to substitute the current panels.

O contexto economico atual tem provocado a maior exposicao das empresas brasileiras a concorrencia internacional, impondo desafios e oportunidades. As pequenas e medias empresas brasileiras (PMEs), sao as mais vulneraveis face a escassez de recursos e custos de producao, dentre outros aspectos. Os arranjos produtivos locais (APLs) ou clusters sao importantes modos de organizacao da producao das PMEs. Esses modos de producao sao considerados vitais na geracao de emprego e renda para o pais. As caracteristicas desses arranjos que dimensionam a sua dinâmica e crescimento sao temas relevantes de pesquisa em varias regioes e paises, pela importância economica e social, amplamente difundidos nos ultimos anos por pesquisadores e entidades. O presente estudo aborda a contribuicao da inteligencia competitiva para o fortalecimento de APLs. Nesse contexto, a dinâmica de APLs e os seus gargalos tecnologicos e de gestao sao identificados focalizando o segmento de calcados e couros de Jau no Estado de Sao Paulo. Varios aspectos sao abordados em relacao a dinâmica desse arranjo produtivo local, atraves da sua analise comparativa com polos internacionais, especialmente o italiano. Indicando sinais de uma estrategia tipica de clusters industriais, explicitada pela sinergia obtida pela interatividade de troca de informacoes intra-cluster e o esforco em incrementar sua capacidade competitiva.
