Noyori, Ryoji

Ryoji Noyori, 1938–, Japanese chemist, D.Eng. Kyoto Univ., 1967. Noyori was an instructor at Kyoto Univ. from 1963 to 1968. He then joined the faculty at Nagoya Univ., where he is a professor and director of the Research Center for Materials Science. Noyori shared the 2001 Nobel Prize in Chemistry with William Knowles and Barry Sharpless for the development of catalytic asymmetric synthesis, with the work of Noyori and Knowles focusing on the utilizing the process of hydrogenation and that of Sharpless on utilizing oxidation (see oxidation and reduction). Most molecules in nature exist in chiral forms whose structures mirror each other (see Stereoisomers under isomer), with one chiral form often biologically active and the other inactive. Catalytic asymmetric synthesis is an enzymelike process that can quickly produce an excess of one of these chiral forms; it has applications in the production of industrial biomaterials and pharmaceuticals.

Citation styles 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, cannot guarantee each citation it generates. Therefore, it’s best to use 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:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most 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.
