Today’s scientific research is an expensive enterprise funded primarily by taxpayers’ and corporate groups’ monies. All nations want to discover fields of study that promise to create future industries, and dominate these by building up and securing scientific and technological expertise early. However, the conversion of scientific leadership into market dominance remains very much an alchemy. To gain insights into how science becomes technology, we focused on graphene (which shows promise in batteries, sensors, flexible displays and other technologies) as a case study. In particular, we asked whether research on the material is on track to deliver all its technological promises. To answer this question, we analyzed in this paper bibliometric records of scientific journal publications and patents related to graphene. While performing straightforward analyses at the aggregate and temporal level to do so, we stumbled upon evidences that suggest ‘Golden Eras’ of graphene science and technology in the recent past. To confirm this unexpected finding, we developed a novel simulation-based method to determine how the interest levels in graphene science and technology change with time. We then found compelling evidences that these interest levels peaked in 2010 and 2012 respectively, despite the continued growth of journal and patent publications in this area. This suggests that publication numbers in a research topic could sometimes give rise to false positives concerning its importance.

石墨烯科学技术的黄金时代:来自期刊和专利出版物的书目证据

当今的科学研究是一个昂贵的企业,主要由纳税人和企业集团的资金资助。所有国家都希望发现有望创建未来产业的研究领域,并通过尽早建立并确保科学技术专长来主导这些领域。但是,将科学领导力转变为市场主导地位仍然是一个炼金术。为了深入了解科学如何成为技术,我们以案例研究为重点,研究石墨烯(显示出电池,传感器,柔性显示器和其他技术的前景)。特别是,我们询问对材料的研究是否正在按计划实现其所有技术承诺。为了回答这个问题,我们在本文中分析了与石墨烯有关的科学期刊出版物和专利的文献计量记录。在进行总体和时间层面的直接分析时,我们偶然发现了证据,这些证据暗示了最近石墨烯科学技术的“黄金时代”。为了证实这一意外发现,我们开发了一种新颖的基于模拟的方法来确定石墨烯科学技术的兴趣水平如何随时间变化。然后,我们发现有力的证据表明,尽管该领域的期刊和专利出版物持续增长,但这些兴趣水平分别在2010年和2012年达到了顶峰。这表明研究主题中的出版物编号有时可能会引起关于其重要性的误报。为了证实这一意外发现,我们开发了一种新颖的基于仿真的方法来确定石墨烯科学技术中的关注度如何随时间变化。然后,我们发现有力的证据表明,尽管该领域的期刊和专利出版物持续增长,但这些兴趣水平分别在2010年和2012年达到了顶峰。这表明研究主题中的出版物编号有时可能会引起关于其重要性的误报。为了证实这一意外发现,我们开发了一种新颖的基于模拟的方法来确定石墨烯科学技术的兴趣水平如何随时间变化。然后,我们发现有力的证据表明,尽管该领域的期刊和专利出版物持续增长,但这些兴趣水平分别在2010年和2012年达到了顶峰。这表明研究主题中的出版物编号有时可能会引起关于其重要性的误报。
