识别全球数据库中的纳米科学和纳米技术 (nano) 出版物对于分析和跟踪这个不断变化的领域的研究至关重要。制定有效的搜索查询来检索尽可能多的纳米相关出版物，同时排除不相关的出版物，这是一项挑战。本文报告了对完善的纳米搜索例程的重大更新。我们提供九个模块的搜索，与使用 WoS 纳米科学和纳米技术类别 (Nano-WC) 相比，显着增强了 Web of Science (WoS) 的检索。我们比较搜索结果，显示与“Nano*”搜索以及模块之间的模块重叠。对由此产生的 220 万条纳米出版物摘要记录的分析证实了纳米相关研究的巨大跨学科影响力以及该领域的持续强劲增长。按国家划分，中国作为世界领先的纳米出版物生产国的地位不断增强，而美国的增长速度则较慢。印度、伊朗和其他几个新兴经济体的纳米出版物相对较高的增长也很明显。对 2013 年至 2017 年纳米出版物的分析确定了 20 多个新兴主题，主要是在未来几年内容易得到积极研究的能源和二维材料领域。
Identifying nanoscience and nanotechnology (nano) publications in global databases is essential to profile and track research in this ever-changing field. Crafting an effective search query to retrieve as many nano-related publications as feasible, while excluding irrelevant publications, is challenging. This paper reports on a major update to a well-established nano-search routine. We offer a nine-module search that significantly augments retrieval from the Web of Science (WoS) compared with use of the WoS Nanoscience & Nanotechnology Category (Nano-WC). We compare search results, showing modular overlaps with a “Nano*” search, and among the modules. Analyzing the resulting set of 2.2 million nano-publication abstract records affirms the tremendous multidisciplinary reach of nano-related research and the continued strong growth of the field. By country, China has enhanced its role as the world’s leading producer of nano-publications, with slower growth for the USA. Relatively high nano-publication growth is also evident for India, Iran, and several other emerging economies. Analyses of nano-publications for 2013–2017 identify more than 20 emerging topics, primarily in the energy and two-dimensional material domains that are apt to be actively researched in the coming few years.
