Peter P. T. Sah and the Synthesis of Vitamin C in China and Europe
EASTM 20 (2003 ): 92-98 Peter P. T. Sah and the Synthesis of Vitamin C in China and Europe Zhang Li [Zhang Li is Associate Professor at the Institute for the History of Natural Sci ence, Chinese Academy of Sciences. She has published a number of articles on the history of modern chemistry of both the West and China and the social his tory of science in twentieth-century China, including studies on the influence of higher education reform on chemical education in the 1950s in China (1992) and the coordination between national needs and scientists' autonomy during 1949-/965 (2003). She recently received her doctoral degree in the Philosophy of Science from Peking University, completing a dissertation on the institution alization of science in the People's Republic of China.

Curriculum Vitae Prof. Dr. Adolf Otto Reinhold Windaus
Curriculum Vitae Prof. Dr. Adolf Otto Reinhold Windaus Name: Adolf Otto Reinhold Windaus Lebensdaten: 25. Dezember 1876 - 9. Juni 1956 Adolf Windaus war ein deutscher Chemiker. Er untersuchte Naturstoffe, vor allem die biochemisch wichtigen Sterine und ihren Zusammenhang mit anderen Naturstoffen. Er entdeckte die chemische Verwandtschaft von Cholesterin und Gallensäure. Außerdem lieferte er Arbeiten über Vitamine, vor allem das Vitamin D. Zwischen 1927 und 1931 gelang ihm die Isolierung mehrerer D-Vitamine. Seine Forschungen bildeten die Grundlage für später von seinen Schülern durchgeführten Arbeiten über die menschlichen Sexualhormone. Für seine Verdienste um die Erforschung des Aufbaus der Sterine und ihres Zusammenhangs mit den Vitaminen wurde Adolf Windaus 1928 mit dem Nobelpreis für Chemie ausgezeichnet. Akademischer und beruflicher Werdegang Adolf Windaus begann 1895 ein Studium der Medizin an der Universität Freiburg. Er wechselte nach Berlin, wo er 1897 das Physikum bestand. 1899 wurde er in Freiburg mit einer Arbeit über Neue Beiträge zur Kenntnis der Digitalisstoffe promoviert wurde. 1901 war er zunächst in Berlin als Assistent von Emil Fischer (Nobelpreis für Chemie 1902) tätig. Während dieser Zeit wandte er sich zunehmend chemischen Fragestellungen zu. Außerdem begann er mit seinen Forschungen zu den Sterinen. 1903 habilitierte er sich in Freiburg mit einer Arbeit über Cholesterin. 1906 erhielt er eine außerordentliche Professur an der Universität Göttingen. Im Anschluss wechselte er für zwei Jahre an die Universität Innsbruck, wo er eine außerordentliche Professur für angewandte medizinische Chemie erhielt. 1915 ging er zurück nach Göttingen, wo er als Nachfolger von Otto Wallach (Nobelpreis für Chemie 1910) Ordinarius für Chemie wurde. Dort blieb er bis zu seiner Emeritierung im Jahr 1944. -

Peptide Chemistry up to Its Present State
Appendix In this Appendix biographical sketches are compiled of many scientists who have made notable contributions to the development of peptide chemistry up to its present state. We have tried to consider names mainly connected with important events during the earlier periods of peptide history, but could not include all authors mentioned in the text of this book. This is particularly true for the more recent decades when the number of peptide chemists and biologists increased to such an extent that their enumeration would have gone beyond the scope of this Appendix. 250 Appendix Plate 8.

Philip D. Lane Ziegler-Natta Catalysis: the Nature of the Active Site Literature Seminar April 3, 1992 Karl Ziegler, While Study
47 Ziegler-Natta Catalysis: The Nature of the Active Site Philip D. Lane Literature Seminar April 3, 1992 Karl Ziegler, while studying ethylene insertion into aluminum-alkyl bonds, serendipi tously discovered the effect transition metals had on ethylene polymerization. He and Guilio Natta made significant contributions to the catalytic polymerization of olefins using a transition metal from groups 4-8 and an organometallic from groups 1, 2, or 13, the most famous com bination being TiC4 + Al(C2H5)3 for the polymerization of polyethylene. The Nobel Prize in Chemistry was awarded to them in 1963 for their contributions in this area [l,2]. The impor tance of this catalytic process can be seen by the amount of polyethylene produced in the U.S. In 1990, 8.3 billion lbs. of high-density polyethylene were produced [3]. The heterogeneous nature of Ziegler-Natta catalysts make them difficult to study [l,4,5]. Despite improved techniques for studying surfaces, information on an atomic level about the active sites remains elusive. For example, the surface reaction of [Zr(allyl)4] with SiQi leads to different surface species [5]. It is not clear which of the resulting surface species is responsible for the polymerization process. Various mechanisms [6,7] have been proposed for Ziegler-Natta catalysis, with the most widely accepted proposal from Cossee and Adman (Figure 1). The aluminum-alkyl is suggested to be responsible for alkylating the transition metal which is in an octahedral environment with one site vacant. Ethylene is thought to coordinate, followed by direct insertion into the metal-alkyl bond of the transition metal.
