(本文发表在《Scientometrics》 March 2013 , Volume 94 , Issue 3 , pp 1037-1056 ) Visualization of patents and papers in terahertz technology: a comparative study Guifeng LIU Abstract Terahertz technology is one of the most promising research areas in the 21st century. In this work, we intend to compare the research status quo on terahertz technology between 1990 and 2010 using knowledge domain visualization techniques. Our data consists of 633 patents retrieved from Aureka management platform and 10,344 journal articles indexed in the ISI web of knowledge. Our analysis is a combination of two information visualization tools for analysis, Aureka and CiteSpace. Aureka is allowed for the analysis of patents filed/granted each year, priority country, inventors, assignees, citation counting, and cluster analysis, while networks of co-authors, countries, institutions, document co-citation networks and document co-citation clusters, are performed by CiteSpace. This research provides a comprehensive domain visualization map of innovation and knowledge in the area of terahertz technology. Our result shows that Aureka and CiteSpace are two promising visualization approaches to analyze patents and papers in any given field.

在室温下,利用太赫兹时域光谱技术获得了一系列毒品(吗啡及其盐酸盐,可卡因,可待因,哌替啶,罂粟碱和蒂巴因)的低频振动光谱。利用密度泛函理论对吗啡进行结构优化和低频振动计算。结合理论计算,吗啡在太赫兹波段的吸收归结为分子间/分子内的集体或晶格振动模式。结果表明,不同的毒品在太赫兹波段呈现不同的吸收特征,因此可以利用该技术对毒品进行检测。 Nuclear Science and Techniques 21 (2010) 209–213 Cited by: 1, Investigation of solid-state reaction by terahertz time-domain spectroscopy Nuclear Science and Techniques 22(2011) 139–143 2, SOLID-STATE REACTION BETWEEN P-BENZOQUINONE AND 4,4 '-BIPHENOL: A THz TIME-DOMAIN SPECTROSCOPIC STUDY JOURNAL OF APPLIED SPECTROSCOPY78(2011) 318-325
药物的多晶型现象, 即同一物质具有两种或两种以上的空间排列和晶胞参数, 生成完全不同类型的晶体。 制备并测量了呋喃苯胺酸 五种不同的 同质多晶变体在 0.2-1.6 THz 频率范围内的吸收系数和折射指数的信息,并同直接购买的未处理的呋喃苯胺酸进行比较。 研究发现太赫兹光谱 技术具有鉴定 药物不同晶型的可能性,并且 在制药工业和质量控制领域的有潜在的应用前景。 Bull Korean Chem Soc 30 (10), (2009), 2265-2268 Cited by: 1, Conformational and Synthon Polymorphism in Furosemide (Lasix), CRYSTAL GROWTH DESIGN 10 (4): 1979-1989 APR 2010 2, Terahertz pulsed spectroscopy and imaging for pharmaceutical applications: A review INTERNATIONAL JOURNAL OF PHARMACEUTICS2011,417(1-2):48-60 3, Novel furosemide cocrystals and selection of high solubility drug forms JOURNAL OF PHARMACEUTICAL SCIENCES2012,101(2),664-680
