Warburg Effect(S)—A Biographical Sketch of Otto Warburg and His Impacts on Tumor Metabolism Angela M
Otto Cancer & Metabolism (2016) 4:5 DOI 10.1186/s40170-016-0145-9 REVIEW Open Access Warburg effect(s)—a biographical sketch of Otto Warburg and his impacts on tumor metabolism Angela M. Otto Abstract Virtually everyone working in cancer research is familiar with the “Warburg effect”, i.e., anaerobic glycolysis in the presence of oxygen in tumor cells. However, few people nowadays are aware of what lead Otto Warburg to the discovery of this observation and how his other scientific contributions are seminal to our present knowledge of metabolic and energetic processes in cells. Since science is a human endeavor, and a scientist is imbedded in a network of social and academic contacts, it is worth taking a glimpse into the biography of Otto Warburg to illustrate some of these influences and the historical landmarks in his life. His creative and innovative thinking and his experimental virtuosity set the framework for his scientific achievements, which were pioneering not only for cancer research. Here, I shall allude to the prestigious family background in imperial Germany; his relationships to Einstein, Meyerhof, Krebs, and other Nobel and notable scientists; his innovative technical developments and their applications in the advancement of biomedical sciences, including the manometer, tissue slicing, and cell cultivation. The latter were experimental prerequisites for the first metabolic measurements with tumor cells in the 1920s. In the 1930s–1940s, he improved spectrophotometry for chemical analysis and developed the optical tests for measuring activities of glycolytic enzymes. Warburg’s reputation brought him invitations to the USA and contacts with the Rockefeller Foundation; he received the Nobel Prize in 1931. -

Garrison Shapiro Professor of Chemistry Head of the Department of Chemistry *Signatures are on file in the Graduate School iii ABSTRACT Transition metal catalyzed reactions are among the most powerful and direct approaches for the synthesis of organic molecules. During the past several decades, phosphorous-containing ligands have been extensively studied in transition metal - catalyzed transformations particularly asymmetric hydrogenations. Development of new chiral ligands and efficient catalyst systems for various prochiral unsaturated substrates in asymmetric hydrogenations are the focus of this dissertation. An important family of atropisomeric biaryl bisphosphine ligands, C3*-TunePhos and related bisaminophosphines have been designed and synthesized. The Ru catalysts of the highly modular C3*-TunePhos have been proved to be highly efficient (up to 99.8% ee, up to 1,000,000 TON) for practical asymmetric hydrogenations of a wide range of unfunctionalized ketones as well as α-, β- keto esters and N-2-substituted allylphthalimides. The synthetic utility of bisaminophosphine ligands was studied for rhodium-catalyzed asymmetric hydrogenations of α-dehydroamino acid esters, affording up to 98% ee’s. -
MICROREVIEW Substrate Activation in the Catalytic Asymmetric

Chem. 2015, 5293–5303, which has been published in final form at http://onlinelibrary.wiley.com/doi/10.1002/ejoc.201500588/pdf. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving." Substrate Activation in the Catalytic Asymmetric Hydrogenation of N-Heteroarenes Bugga Balakrishna,[a] José Luis Núñez-Rico[a] and Anton Vidal-Ferran*[a],[b] Keywords: Asymmetric catalysis / Enantioselectivity / Iridium / Palladium / Nitrogen heterocycles / Hydrogenation. Different methods for transforming N-heteroarenes into more reactive derivatives for catalytic asymmetric hydrogenation are highlighted. The first strategy consists of facilitating hydrogenation by the formation of positively charged derivatives of the heteroarene. Catalyst deactivation processes arising upon binding of the substrate to the metal center can thus be prevented and, additionally, hydrogenation of positively charged heteroarenes may also be more favored than that of their neutral analogues. The second strategy is based on introducing a ligating group onto the substrate to assist its coordination to the metal center and facilitate hydrogenation by chelation assistance. The last strategy involves breaking the aromaticity of the heteroarene by inducing a doublebond migration process. This microreview summarizes advances made in the above strategies, which have allowed the development of highly enantioselective catalytic hydrogenation of N-heteroarenes for the production of fully or partially saturated chiral heterocycles. Introduction synthesizing fully or partly reduced heteroaromatic derivatives in Enantiopure organic compounds are important constituents of enantiomerically pure form (Scheme 1).[8] This synthetic strategy commercially produced chemicals including plastics, active also benefits from a great diversity of starting materials. -

Notes Rec. R. Soc. Lond. 57 (1), 85–105 (2003) doi 10.1098/rsnr.2003.0197 AN ANTIPODEAN LABORATORY OF REMARKABLE DISTINCTION by NORMAN N. GREENWOOD1 FRS AND JOHN A. SPINK2 1Department of Chemistry, The University of Leeds, Leeds LS2 9JT, UK 2Department of History and Philosophy of Science, The University of Melbourne, Victoria, 3010, Australia SUMMARY In an astonishingly short period in September 1939, while on a brief visit from England, F.P. Bowden (FRS 1948) conceived the need, and obtained the approval of the Australian Council for Scientific and Industrial Research (CSIR), to establish a wartime friction and bearings research laboratory within the University of Melbourne. He recruited a galaxy of young talent, which during the following six years made major contributions to four very diverse defence-related problems. The infant laboratory survived the peace and eventually evolved into the internationally admired Division of Tribophysics. Many of the original members of the group went on to distinguished careers in Australia, the UK and elsewhere. The story of the exciting early days of the laboratory and the subsequent achievements of its staff are briefly described. INTRODUCTION The year 2003 marks the centenary of the birth of F.P. Bowden FRS (figure 1). In September 1939, at the outbreak of World War II, Philip Bowden was on a brief family visit to Australia. He had been born in Hobart, Tasmania, in 1903 and obtained his BSc and MSc from the University of Tasmania.1 He then went to Gonville and Caius College, Cambridge, as an Exhibition of 1851 Overseas Research Scholar to study for his PhD under Dr Eric Rideal (later Sir Eric Rideal FRS). -
Physics 1928 OWEN WILLANS RICHARDSON
Physics 1928 OWEN WILLANS RICHARDSON <<for his work on the thermionic phenomenon and especially-for the discovery of the law named after him>> Physics 1928 Presentation Speech by Professor C. W. Oseen, Chairman of the Nobel Committee for Physics of the Royal Swedish Academy of Sciences Your Majesty, Your Royal Highnesses, Ladies and Gentlemen. Among the great problems that scientists conducting research in electro- technique are today trying to solve, is that of enabling two men to converse in whatever part of the world each may be. In 1928 things had reached the stage when we could begin to establish telephonic communication between Sweden and North America. On that occasion there was a telephone line of more than 22,000 kilometres in length between Stockholm and New York. From Stockholm, speech was transmitted via Berlin to England by means of a cable and overhead lines; from England by means of wireless to New York; then, via a cable and lines by land, over to Los Angeles and back to New York, and from there by means of a new line to Chicago, returning finally to New York. In spite of the great distance, the words could be heard distinctly and this is explained by the fact that there were no fewer than 166 amplifiers along the line. The principle of construction of an amplifier is very simple. A glowing filament sends out a stream of electrons. When the speech waves reach the amplifier, they oscillate in tune with the sound waves but are weakened. The speech waves are now made to put the stream of electrons in the same state of oscillation as they have themselves. -

Dieser gilt als der Entdecker der Glaselek- trode (Cremer, 1906). Ihr Vater stammte aus Ürdingen. Großvater und Vater der Mutter, Els- beth Rothmund, waren berühmte Kliniker an der Münchner Universität. Ihr Onkel Viktor Rothmund war Ordinarius für Physikalische Chemie in Prag. Die Berufung des Vaters nach Köln (1909) und nach Berlin an die Tierärztilche Hochschule (1911) war ein schwerer Eingriff in dem jungen Leben der gebürtigen Münchnerin. Zuerst wurde ihr in Köln der Dialekt radikal abgewöhnt, und der Schulwechsel in das preußische Berlin war wohl Erika Cremer auch nicht ganz im Sinne der kleinen Erika. Hei- misch wurde sie weder in Köln noch Berlin. Ihre Sehnsucht waren München und Miesbach wo sie einen Teil ihrer Kindheit verbrachte und vorallem die Alpen (Patat, 1965; Bobleter, 1990, 1997; Stöger, 1990). Mit dem Reifezeugnis an der Oberrealschule in der Kochstraße in Berlin immatri- kulierte sich Erika Cremer im Sommer 1921 an der Friedrich-Wilhelm-Universität in Berlin. -
Curriculum Vitae Prof. Dr. Cyril Norman Hinshelwood
Curriculum Vitae Prof. Dr. Cyril Norman Hinshelwood Name: Cyril Norman Hinshelwood Lebensdaten: 19. Juni 1897 ‐ 9. Oktober 1967 Cyril Norman Hinshelwood war ein britischer Chemiker. Er untersuchte Aspekte der chemischen Reaktionskinetik. Nach ihm ist der Langmuir‐Hinshelwood‐Mechanismus benannt. Er beschreibt die Reaktion zweier Ausgangsstoffe an einer Katalysator‐Oberfläche. Für seine Forschungen über die Mechanismen chemischer Reaktion wurde Hinshelwood 1956 mit dem Nobelpreis für Chemie ausgezeichnet. Akademischer und beruflicher Werdegang Cyril Norman Hinshelwood war sehr begabt und bekam ein Stipendium für die University of Oxford zugesprochen. Wegen des Ersten Weltkriegs konnte er dies jedoch nicht in Anspruch nehmen. Stattdessen war er in dieser Zeit als Chemiker in einer Sprengstofffabrik in Queensferry, Schottland tätig. 1919 ging er ans Balliol College in Oxford, wo er einen durch die Nachkriegszeit verkürzten Kurs in Chemie besuchen durfte. Seine Auffassungsgabe der chemischen Prinzipien war so herausragend, dass er erneut für ein Stipendium vorgeschlagen wurde. In Oxford erlangte Hinshelwood den Bachelor‐ und Master‐Grad. Von 1921 bis 1937 arbeitete er am Trinity College in Oxford als Tutor. 1937 erhielt er eine Professur für Chemie an der Universität Oxford. Auch während des Zweiten Weltkriegs war er für die Kriegsproduktion tätig, so unter anderem bei der Herstellung von Gasmasken und Penicillin. Nobelpreis für Chemie 1956 Die chemische Kinetik, die Geschwindigkeit und Mechanismus einer chemischen Reaktion untersucht, war zu Beginn des 20. Jahrhunderts noch wenig erforscht. Hinshelwood hatte großes Interesse an den Mechanismen derartiger chemischer Prozesse. Es wurde während des Ersten Weltkriegs noch verstärkt, als er in einer Munitionsfabrik beschäftigt war, wo er sich mit der Chemie von explosiven Stoffen beschäftigte.
