Global patent analysis of power lithium-ion battery separator
The development of technologies related to power lithium-ion battery separator has been taken place in recent years. In order to provide appropriate decision references for the industry development, patent analysis was carried out. On the basis of Derwent Innovation Index (DII), global patents related to power lithium-ion battery separator were analyzed from aspects of global…

An informatics-based analysis of developments to date and prospects for the application of microalgae in the biological sequestration of industrial flue gas
The excessive emission of flue gas contributes to air pollution, abnormal climate change, global warming, and sea level rises associated with glacial melting. With the ability to utilize NOx as a nitrogen source and to convert solar energy into chemical energy via CO2 fixation, microalgae can potentially reduce air pollution and relax global warming, while…

Navigating the innovation trajectories of technology by combining specialization score analyses for publications and patents: graphene and nano-enabled drug delivery
In this study, we combine the specialization scores for publications and patents (the latter is a new indicator of cross-disciplinary engagement) to achieve more comprehensive navigation of the innovation trajectory of a technology. The patent specialization score draws upon counterpart research publication indicator concepts to measure patent diversity. Two nano-based technologies—Nano-enabled drug delivery (NEDD) and…
