纳米科学与技术的多学科认知内涵
Multidisciplinary Cognitive Content of Nanoscience and Nanotechnology
摘要:
本文探讨了纳米技术的认知演变和学科多样性,通过纳米期刊文章标题中使用的术语来表达。该分析基于NanoBank书目数据库,该数据库包含1981年至2004年间发表的287,106篇纳米文章。我们对标题词进行了多方面的分析,重点是100个最常见的术语。标题术语的层次聚类揭示了纳米研究认知发展的三个不同时期:形成期(1981-1990),早期(1991-1998)和当前(1998年后)。早期的特点是引入薄膜沉积技术,而目前的特点是增加对碳纳米管和纳米颗粒的研究。我们介绍了一种方法来确定纳米技术的学科组成部分。它表明纳米研究正在许多不同的母学科中进行。目前,只有5%的文章发表在专门的纳米期刊上。我们发现,今天大约85%的纳米研究是多学科的。学科成分的层次聚类显示,当前纳米科学的认知内容可以分为九个集群。一些团簇占纳米研究的很大一部分,并与凝聚态和应用物理学,材料科学和分析化学等母学科相关联。其他集群代表了纳米研究的小得多的部分,但在认知上是不同的。按照规模递减的顺序,这些领域是:聚合物科学,生物技术,普通化学,表面科学和药理学。发表在纯纳米期刊上的研究的认知内容与发表在凝聚态和应用物理期刊上的纳米研究最接近。
英文摘要:
This article examines the cognitive evolution and disciplinary diversity of nanotechnology as expressed through the terminology used in titles of nano journal articles. The analysis is based on the NanoBank bibliographic database of 287,106 nano articles published between 1981 and 2004. We perform multifaceted analyses of title words, focusing on 100 most frequent terms. Hierarchical clustering of title terms reveals three distinct time periods of cognitive development of nano research: formative (1981-1990), early (1991-1998), and current (after 1998). Early period is characterized by the introduction of thin film deposition techniques, while the current period is characterized by the increased focus on carbon nanotube and nanoparticle research. We introduce a method to identify disciplinary components of nanotechnology. It shows that the nano research is being carried out in a number of diverse parent disciplines. Currently only 5% of articles are published in dedicated nano-only journals. We find that some 85% of nano research today is multidisciplinary. Hierarchical clustering of disciplinary components reveals that the cognitive content of current nanoscience can be divided into nine clusters. Some clusters account for a large fraction of nano research and are identified with such parent disciplines as the condensed matter and applied physics, materials science, and analytical chemistry. Other clusters represent much smaller parts of nano research, but are as cognitively distinct. In the decreasing order of size, these fields are: polymer science, biotechnology, general chemistry, surface science, and pharmacology. Cognitive content of research published in nano-only journals is closest to nano research published in condensed matter and applied physics journals.
