THE LONG SEARCH FOR STABLE TRANSITION METAL ALKYLS Nobel Lecture, December 11, 1973 by G EOFFREY W ILKINSON Imperial College of Science & Technology, London, England Chemical compounds in which there is a single bond between a saturated car- bon atom and a transition metal atom are of unusual importance. Quite aside from the significance and role in Nature of the cobalt to carbon bonds in the vitamin B 12 system and possible metal to carbon bonds in other biological systems, we need only consider that during the time taken to deliver this lec- ture, many thousands, if not tens of thousands of tons of chemical compounds are being transformed or synthesised industrially in processes which at some stage involve a transition metal to carbon bond. The nonchemist will pro- bably be most familiar with polyethylene or polypropylene in the form of do- mestic utensils, packaging materials, children’s toys and so on. These materials are made by Ziegler-Natta* or Philipps’ catalysis using titanium and chro- mium respectively. However, transition metal compounds are used as catalysts in the synthesis of synthetic rubbers and other polymers, and of a variety of simple compounds used as industrial solvents or intermediates. For example alcohols are made from olefins, carbon monoxide and hydrogen by use of cobalt or rhodium catalysts, acetic acid is made by carbonylation of methanol using rhodium catalysts and acrylonitrile is dimerised to adiponitrile (for nylon) by nickel catalysts. We should also not forget that the huge quantities of petroleum hydrocarbons processed by the oil and petrochemical industry are re-formed over platinum, platinum-rhenium or platinum-germanium sup- ported on alumina. -

H2O - this is a base, since it gets the proton that the acid lost. Now, here comes an interesting idea: + H3O - this is an acid, because it can give a proton. Cl¯ - this is a base, since it has the capacity to receive a proton. + Notice that each pair (HCl and Cl¯ as well as H2O and H3O differ by one proton (symbol = H+). These pairs are called conjugate pairs.

Ian Rae: “Two Croatian Chemists Who Were Awarded the Nobel Prize in Chemistry”
Croatian Studies Review 13 (2017) Ian Rae: “Two Croatian Chemists who were Awarded the Nobel Prize in Chemistry” Ian Rae School of Chemistry University of Melbourne [email protected] Abstract Two organic chemists of Croatian origin, Leopold Ružička and Vladimir Prelog, made significant contributions to natural product chemistry during the twentieth century. They received their university education and research training in Germany and Czechoslovakia, respectively. Both made their careers in Zürich, Switzerland, and both shared the Nobel Prize in Chemistry, in 1939 and 1975, respectively. In this article, I have set the details of their lives and achievements against the education and research climates in Europe and other regions, especially as they apply to the field of chemistry. Key words: Croatia, organic, chemistry, Nobel, Ružička, Prelog 31 Croatian Studies Review 13 (2017) Introduction1 In the twentieth century two organic chemists of Croatian origin were awarded the Nobel Prize in Chemistry. They were Lavoslav (Leopold) Ružička (1887-1976) and Vladimir Prelog (1906-1998), whose awards came in 1939 and 1975, respectively. Both were living and working in Switzerland at the time of the awards and it was in that country – specifically in the city of Zürich – that they performed the research that made them Nobel Laureates. To understand the careers of Ružička and Prelog, and of many other twentieth century organic chemists, we need to look back to the nineteenth century when German chemists were the leaders in this field of science. Two developments characterise this German hegemony: the introduction of the research degree of Doctor of Philosophy (PhD), and the close collaboration between organic chemists in industry and university. -
Materials Science
Materials Science Materials Science is an interdisciplinary field combining physics (fundamental laws of nature), chemistry (interactions of atoms) and biology (how life interacts with materials) to elucidate the inherent properties of basic and complex systems. This includes optical (interaction with light), electrical (interaction with charge), magnetic and structural properties of everyday electronics, clothing and architecture. The Materials Science central dogma follows the sequence: Structure—Properties—Design—Performance. This involves relating the nanostructure of a material to its macroscale physical and chemical properties. By understanding and then changing the structure, material scientists can create custom materials with unique properties. The goal of the materials science minor is to create a cross-disciplinary approach to fundamental topics in basic and applied physical sciences. Students will gain experience and perspectives from the disciplines of chemistry, physics and biology. The minor places a strong emphasis on current nanoscale research methods in addition to the basics of electronic, optical and mechanical properties of materials. Any student with an interest in pursuing the cross-disciplinary minor in materials science should consult with the coordinator of the minor. Students are encouraged to declare their participation in their sophomore year but no later than the end of the junior year. Students also should seek an adviser from participating faculty.

Biographical Memoir COPYRIGHT 1974 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. THEODORE WILLIAM RICHARDS January 31, 1868-April 2, 1928 BY JAMES BRYANT CONANT HEODORE WILLIAM RICHARDS was a precocious son of distin- Tguished parents. He was born in Philadelphia on January 31, 1868, the third son and fifth child of William Trost Richards and Anna Matlack Richards, who had been married on June 30, 1856. As strict members of the Society of Friends, the Matlack family looked askance at a young man who earned his living painting pictures. Anna was "read out of meeting." The Quaker marriage ceremony took place in the house of a friend. The first months of the honeymoon were devoted to the com- position and illustration of a manuscript volume of poems for the lady who had first brought the young couple together. A mutual interest in Browning and Tennyson had started an acquaintanceship which rapidly became a romance. An old friend and fellow artist of Philadelphia reminiscing long after W. T. Richards had established his reputation as a landscape painter said, "He amazed me by getting married and resigning his position as designer [in a local firm manufacturing gas fixtures] in order to devote himself entirely to his art. -
From Physical Chemistry to Chemical Physics, 1913-1941
International Workshop on the History of Chemistry 2015 Tokyo From Physical Chemistry to Chemical Physics, 1913-1941 Jeremiah James Ludwig-Maximillian University, Munich, Germany There has never been one unique name for the intersection of chemistry and physics. Nor has it ever been defined by a single, stable set of methods. Nevertheless, it is possible and arguably rewarding to distinguish changes in the constellation of terms and techniques that have defined the intersection over the years. I will speak today about one such change, the advent and ascendancy of chemical physics in the interwar period. When the young Friedrich Wilhelm Ostwald first began to formulate his campaign for “physical chemistry” in 1877, he used the term almost interchangeably with two others, “general chemistry” and “theoretical chemistry.” According to his vision of what would soon become a new chemical discipline, physical chemistry would investigate and formulate the general principles that underlie all chemical reactions and phenomena. The primary strategy that he and his allies used to generate these principles was to formulate mathematical “laws” or “rules” generalizing the results of numerous experiments, often performed using measuring apparatus borrowed from physics. Their main fields of inquiry were thermochemistry and solution theory, and they avoided and often openly maligned speculations regarding structures or mechanisms that might underlie the macroscopic regularities embodied in their laws.1 In the first decades of the 20th-century, the modern atomic theory was firmly established, and with only a slight delay, the methods of 19th-century physical chemistry lost a considerable proportion of their audience. Theories relying upon atomistic thinking began to reshape the disciplinary intersections of chemistry and physics, and by the end of the 1930s, cutting-edge research into the general principles of chemistry looked quite different than it had at the turn of the century.
