2 Background Corrosion costs are estimated at $2.5 Trillion globally for identification, treatment and repair (NACE Impact 2016) Microbiologically Influenced Corrosion (MIC) is a type of corrosion caused by biological activity. While MIC is involved in most corrosion processes to some extent, estimates of its impact are largely unsubstantiated and is a topic of study for our project. MIC is an often misunderstood and misdiagnosed corrosion mechanism 20photo.jpg The synergistic effects the bacterial biofilms have on metallic corrosion is not well understood 1

3 Background Like many interdisciplinary problems such as risk, part of the challenge in diagnosing and treating MIC is the complexity of interactions and its knowability If you don t know what MIC is, you may know it by any number of synonyms used: Microbial Corrosion, Microbiologically Influenced Corrosion, Biocorrosion, Biodegredation MIC Abstract Wordcloud 2

4 Background Bibliometrics is the study and analysis of citations in typically academic literature This technique is often used for modelling knowledge transfer and the growth of research fields By using this method we hoped to understand the research landscape for MIC with the goal of understanding if the interdisciplinarity of the topic was hindering research efforts 3

5 Objectives Better understand the MIC research landscape Assess the interdisciplinarity of the research published to date on MIC Understand the linkages between members of different scientific fields when researching a multidisciplinary field Understand how better to communicate multidisciplinary topics in traditional academic venues 4

6 Research Methodology The first data set was acquired from Scopus and used a fairly generic search string looking for Bacteria and Corrosion Restricted to journal articles and any papers published between This search returned 3,413 papers which were then broken down by discipline and keyword 5

7 Research Methodology Took a step forward using the more sophisticated Web of bibliometric database managed by Clairvate Analytics Using VOSViewer clustering and imaging software we began constructing maps of MIC research CitenetExplorer was used for tracing the roots of the field Search string TS = (Corrosion) AND TS = (Bacteria OR Archaea OR Microb*) NOT TS = (Implant) NOT TS = (Human) NOT TS = (Microbalance) 5,408 documents were retrieved 59% consisting of journal articles and 30% from conference papers Hashemi et al.

8 Results One can see that over the last 16 years the amount of articles from various fields has grown tremendously This satisfied our first question about the growth of MIC as a research field in all associated subjects Annual Trends in MIC Articles 7

9 Results As previously mentioned MIC has many synonymous terms and can be approached for a variety of different viewpoints depending on your field of study Biofilm is the most common keyword overall. With the majority of articles in Microbiology, Biochemistry and s Articles by discipline with specific keywords 8

18 Key Findings Corrosion and Applied Microbiology are the most heavily cited journals in our data set Journals in different fields are less commonly cited together Within the most frequent linkages there are few cross disciplinary linkages This implies that MIC research is siloed while still being interdisciplinary 17

19 Key Findings Statistical Analysis Confirmed 1. Researchers have a tendency to cite members of their own home discipline 2. Specific keywords are tied more strongly to certain disciplines than others 3. Keywords influence the types of articles that will cite it These conclusions confirmed in our mind that MIC research is likely segregated by discipline and is not flowing optimally 18

20 Conclusions Further computation will need to be done to determine if these results are symptoms of a lack of interdisciplinarity in MIC research Mapping and analysis of MIC articles suggest a potential citation bias exists This would explain the lack of frequent cross disciplinary linkages 19

21 Future Work To further understand the interdisciplinarity of MIC as a research field more work is required Using the Rao-Stirling equation which calculates uses the concept of intellectual distance to measure the diversity of a group of citations (Porter 2007) 1, The higher the I value the more interdisciplinary the paper could be considered 20

22 Future Work Better assess the impact and scope of MIC failures Better understand the best venues to present relevant industry information, to reach relevant audiences This methodology has been used to examine the emergence and maturity of interdisciplinary fields (i.e., biotechnology) Bibliometrics could also be used to examine how other interdisciplinary fields are defined, scoped, and deepened through academic and industry researchers; which venues (academic or industry journals/conferences) and which collaborations are more likely to bridge knowledge domains 21
