In 1957 Chen-Ning Yang in the field of Physics along with Tsung-Dao Lee won the Nobel Prize for their penetrating investigation of the so-called parity laws which has led to important discoveries regarding the elementary particles whose results were listed as references in the publications of Materials Science Journals. Yuan T. Lee shared Nobel Prize with Dudley R. Herschbach and John C. Polanyi in 1986 for their contributions concerning the dynamics of chemical elementary processes. In 2008, Roger Y. Tsien in the field of Chemistry along with Osamu Shimomura and Martin Chalfie won the Nobel Prize for the discovery and development of the green fluorescent protein which led to further discovery that are covered as a references in the list of Materials Science Journals.
