Koichi Tanaka, 1959–, Japanese engineer, B.S. Tohoku Univ., 1983. He has been a researcher at Shimadzu Corporation in Kyoto, Japan, since 1983. Tanaka shared the 2002 Nobel Prize in Chemistry with John Fenn and Kurt Wüthrich for the development of methods for identifying and analyzing the structure of biological macromolecules. Before their work, mass spectroscopy could be used to analyze only fairly small molecules. Tanaka is credited with pioneering matrix-assisted laser desorption/ionization (MALDI), a mass-spectroscopy technique in which proxy substances called matrixes are used to absorb laser energy and promote the ion formation of large molecules, which are otherwise prone to thermal degradation during analysis.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
