Refining search terms for nanotechnology 总被引:5,自引:3,他引:2
Alan L. Porter Jan Youtie Philip Shapira David J. Schoeneck 《Journal of nanoparticle research》2008,10(5):715-728
The ability to delineate the boundaries of an emerging technology is central to obtaining an understanding of the technology’s
research paths and commercialization prospects. Nowhere is this more relevant than in the case of nanotechnology (hereafter
identified as “nano”) given its current rapid growth and multidisciplinary nature. (Under the rubric of nanotechnology, we
also include nanoscience and nanoengineering.) Past efforts have utilized several strategies, including simple term search
for the prefix nano, complex lexical and citation-based approaches, and bootstrapping techniques. This research introduces
a modularized Boolean approach to defining nanotechnology which has been applied to several research and patenting databases.
We explain our approach to downloading and cleaning data, and report initial results. Comparisons of this approach with other
nanotechnology search formulations are presented. Implications for search strategy development and profiling of the nanotechnology
field are discussed.

Synchrotron protein crystallography (PX) is one of the most powerful and dominant tools for determining the three-dimensional structures of biological macromolecules. At the National Synchrotron Radiation Research Center, TLS 13B1 is the first dedicated energy-tunable and highly automated PX beamline for efficiently solving de novo protein structures in Taiwan and has been open for users since September 2005. With remote access, user support services, and annual PX training courses over 17 years, the number of user groups at TLS 13B1 has grown from 11 to 139. In total, 1,429 projects were supported, and 2090 experiments were hosted during 67,846 hr of beamtime. This paper describes the photon source, beamline components, experimental station equipment, beamline software, beamline application process, and results from our users. 相似文献
