Benchmarking Results: Assessment of U.S. Leadership in Chemical Engineering at Large

Chapters 3 and 4 present the results of the benchmarking exercise that the Panel undertook in assessing the international competitiveness of U.S. research in chemical engineering. Chapter 3 summarizes the results for chemical engineering at large, while Chapter 4 presents the results for each subarea of chemical engineering. The approach that the Panel followed for the benchmarking exercise was outlined in Section 2.2.

The presentation of results in this chapter is structured as follows: Section 3.1 describes the composition of the Virtual World Congress (VWC) for each subarea of chemical engineering and draws conclusions on the leadership of U.S. chemical engineering research at large. The detailed analysis of the VWC composition for each subarea is given in Chapter 4. Section 3.2 summarizes the analysis of chemical engineering publications and citations, while Section 3.3 presents the results of a patent analysis. Section 3.4 examines the distribution of prizes, awards, and other recognitions, and Section 3.5 summarizes the Panel’s assessment of the current health of U.S. research in chemical engineering at large.

International Benchmarking of U.S. Chemical Engineering Research Competitiveness The fourth column shows the total number and the percentages of U.S. and non-U.S. participants (speakers) in the VWC for each subarea. These numbers include duplications, i.e., if a specific person was recommended by two experts for the same congress, the entry in the totals is 2. The fifth column is based on the same information as the middle section, but each participant has been counted once, even if he/she was proposed by several experts. A total of 296 experts in various areas of chemical engineering were engaged to organize the VWC (see Appendix 3A at the end of this chapter): 83% from the United States and 17% from other countries. For the various subareas the percentage of U.S. organizers ranged from 60% (electrochemical processes; green engineering) to 100% (thermodynamics; separation; catalysis; systems, computational, and synthetic biology; materials for cell and tissue engineering; fossil energy extraction and processing; water pollution), depending on the specific subarea. The preponderance of U.S. names is not surprising given the historical strength of chemical engineering in the United States. The composition of the resulting Virtual World Congresses, overall and for the various subareas, is the outcome of significance for this benchmarking exercise. As Table 3.1 indicates, 2,997 researchers were recommended for inclusion in the VWC: 1,897 (63%) from the United States and 1,100 (37%) from other countries. The 63% overall U.S. representation in the VWC is in line with the fractional U.S. representation in the list of most-cited publications for 2000-2006 (74%, see Table 3.3), which is a metric that also denotes relative quality and impact. Consequently, the overall composition of the VWC suggests that U.S. chemical engineering research, at large, is “Dominant, at the Forefront” of developments in the discipline. When we examine the U.S. fractional representation in the VWC for each subarea, we notice that it varies from 42% (biocatalysis and protein engineering) to 77% (transport processes) of all participants, suggesting that U.S. research in every subarea of chemical engineering is either “Dominant, at the Forefront” (65% or more of participants) or “Among World Leaders” (42% to 65% of participants). In Chapter 4, the specific numbers of Table 3.1 for each subarea are analyzed in conjunction with other information, in order to draw conclusions on the relative position of U.S. chemical engineering research in the corresponding subarea.

International Benchmarking of U.S. Chemical Engineering Research Competitiveness 3.2 JOURNAL PUBLICATIONS In this section we will discuss the macroscopic trends, on a worldwide basis, of the publications and citations data collected for five time periods from 1980 to 2006 for the field of chemical engineering at large. Appendix 3B lists all the journals that were considered. They were grouped in the following three categories: journals with broad coverage of chemical engineering research journals with broad coverage of sciences and engineering disciplines, in which chemical engineers publish leading journals for each subarea of chemical engineering The total number of papers published was found by searching the Web of Science (http://portal.isiknowledge.com/portal.cgi) for all publications during the corresponding period, with the requirement that a co-author had a chemical engineering affiliation in the address field. For the United States, a chemical engineering affiliation is a good indicator that a researcher is involved in chemical engineering research. Recent changes in the affiliation of academic researchers from chemical engineering departments to biological engineering or biomedical engineering departments have been taken into account; biological and biomedical engineering departments populated recently by the transfer of chemical engineers were included in the search and the lists were pruned by eliminating the faculty members in these departments who did not hold a Ph.D. in chemical engineering.. However, for non-U.S. researchers with research activities within the scope of chemical engineering as understood in the United States, the corresponding affiliation is not a very good indicator. Many such researchers are affiliated with departments that do not contain “chemical engineering” in their name. Particular attention on select very active universities in Europe and Japan (e.g. ETH-Zurich and Kyoto University, respectively), was given to include the contributions of the non-U.S. researchers who would qualify as chemical engineers, but the numbers of papers by non-U.S. chemical engineering researchers should be viewed as lower bounds. 3.2.a Summary of the Macro Trends Analysis of publications and citations by chemical engineers in all three groups of journals has revealed the following trends: Trend 1: The relative volume of the U.S.-originated journal publications by chemical engineers, as a fraction of the worldwide total, has been halved over the past 20 years.

OCR for page 39
International Benchmarking of U.S. Chemical Engineering Research Competitiveness Trend 2: U.S. publications in chemical engineering continue to exercise academic leadership with strong scientific and technological impact worldwide. The relative degree of leadership has been decreasing over the past 10 years. Trend 3: The relative volume (as a fraction of the total) of U.S.-originated publications in broadly based chemical engineering journals has been reduced by 25%-30% over the past 10-15 years. Trend 4: The fraction of U.S.-originated contributions, in broadly based chemical engineering journals, with research subjects in the classical coreareas of transport processes, thermodynamics, kinetics and reaction engineering, and process systems engineering, has been reduced by more than the overall fraction in Trend-3, i.e., 50%-60% versus 25%-30% reductions. Trend 5: The fraction of the top-cited (in the top 100 most-cited papers) U.S.-originated publications in broadly based chemical engineering journals has been reduced by one-third over the past 10-15 years. Trend 6: The fraction of chemical engineering contributions in broadly based scientific journals, e.g., Science, Nature, Proceedings of the National Academy of Sciences, has roughly doubled in the past 5-10 years. Among such contributions U.S.-originated publications represent about 90% of the total. Taken together, the implications from the above trends are clear: Implication 1: The volume of research in chemical engineering around the world, especially in the European Union and Asia has been increasing at a higher (European Union) and frantic (Asia) rate compared to that in the United States, but the quality and impact still trail appreciably that in the United States. Implication 2: Research in U.S. chemical engineering has been driven away from the historical core of chemical engineering toward the periphery, where it meets and overlaps with a variety of other sciences (primarily) and engineering disciplines (secondarily). Implication 3: While the quality and impact of U.S. research in chemical engineering is still dominant and at the forefront of developments, this leadership position has been weakened over the past 10-15 years, especially in the core areas of the discipline. In the following paragraphs we will present the details of the data analysis that led to the formation of the above trends and implications.

International Benchmarking of U.S. Chemical Engineering Research Competitiveness 3.2.b Analysis of Publications and Citations from All Journals The number of papers from U.S. chemical engineering researchers has dominated the world output over the past 20 years, as Table 3.2 and Figure 3.1 indicate. However, although the number of U.S.-originated publications has increased by a factor of 3.7, its relative contribution to the world total during the past 20 years has been roughly halved from 71% in the period 1980-1984 to 37% in the period 2000-2006 (Trend 1). This is due to a significantly faster growth in the number of publications from chemical engineering researchers across the world. For example, the factor of growth between the 1980-1984 and 2000-2006 periods for various geographic regions is as follows: Asia (China, Korea, Taiwan, India): 35 Central and South America: 23 European Union (25 countries): 15 Japan: 4 The 3.7-fold increase in the volume of U.S. publications is primarily the result of an impressive growth in productivity of U.S. researchers, given the fact that the yearly rate of growth in the number of researchers has not increased by a similar factor (see Chapter 5 for trends in numbers of PhD graduates). In contrast, most of the gains in the growth of Asian and European Union publications have come as a result of a significant yearly rate of growth in the number of researchers. While the relative volume of U.S.-originated chemical engineering publications, as fraction of the world total, has been halved, the academic impact and leadership of the U.S. chemical engineering output has remained at fairly high levels (Trend 2). For example: TABLE 3.2 Number of Published Papers Originated from Researchers with Chemical Engineering Affiliation at Various Geographic Regions   1980-1984 1985-1989 1990-1994 1995-1999 2000-2006 United States 8,933 14,230 17,528 21,334 32,899 European Union 890 1,715 3,470 7,015 13,442 Japan 1,647 2,386 3,209 4,022 6,978 Canada 1,182 1,617 2,234 2,605 4,246 South America 81 121 271 651 1,863 Asia (China, Korea, Taiwan, India) 958 1,837 3,907 9,930 33,124

International Benchmarking of U.S. Chemical Engineering Research Competitiveness FIGURE 3.1 Number of published papers in chemical engineering from various geographic regions. NOTE: Asia comprises China, Korea, Taiwan, and India, and the European Union is 25 countries. Table 3.3 shows that U.S.-originated publications completely dominated the list of the 100 most-cited publications when the analysis was carried out for the period 1985-1990: 86 of the top 100, 46 of the top 50, 19 of the top 20, and 10 of the top 10. The analysis for the period 2000-2006 indicates a continued but weaker dominance of U.S. publications in the list of the 100 most cited: 73 of the top 100, 37 of the top 50, 13 of the top 20, and 6 of the top 10. It is worth noting that of the 86 most-cited U.S. publications with U.S. chemical engineers as co-authors (period, 1985-1990), 73 had a chemical engineer as the corresponding author, while 13 had a U.S. nonchemical engineer as the corresponding author. In the period 2000-2006, of the 74 most-cited U.S. papers, the corresponding numbers are 50 with a chemical engineer as the corresponding author and 24 with a nonchemical engineer as the corresponding author, indicating an appreciable expansion in interdisciplinary research collaboration. This feature of substantial interdisciplinarity will become more evident later on in this report in Chapter 4. It is also noteworthy that in the period 2000-2006, no

Table 3.4 shows the distribution of the most-cited papers among the various subareas, used to characterize chemical engineering for the purposes of this report, thus underlining the shifts in research emphasis during the past 15-20 years. From the entries of the table it is very clear how the research emphasis has shifted from Area-1 to Areas- 3, 5, and 6. Clearly, numbers of citations vary significantly among the various subareas and may cause uncertainty on the validity of the observed trends. However, these trends will be confirmed with additional data in subsequent paragraphs. It is also interesting to see in what journals the most-cited papers were published. Table 3.5 shows the distribution of the most-cited papers among different groups of papers. These trends will be confirmed with additional data in subsequent paragraphs. The graphs in Figures 3.2 and 3.3 show the evolution of the percentages of published papers from each geographic region with more than 200 and 100 citations, respectively, during the last 20 years. The graph of Figure 3.4, percentage of papers with more than 10 citations, shows a relative parity among the various regions, but this is the group of publications of lesser impact. Note: The numbers in Figures 3.2, 3.3, and 3.4 are percentages of the total number of papers from a given geographic area that satisfy the corresponding citations thresholds. Clearly, the U.S. dominance in academic impact and leadership, demonstrated by the tables and figures is partly due to historical reasons, that is, to the earlier activity of U.S. researchers compared to that of their Asian and EU counterparts. One would expect that as non-U.S. contributions to archival journals increase, their relative impact will increase as well. Indeed, it noteworthy that of the top 100 most-cited papers, 13 have come from
