SAJ Biotechnol 5: 102 Article history: Received: 20 March 2018, Accepted: 29 March 2018, Published: 03 April 2018 Abstract The scientific work of the universal genius the Nobel Laureate George de Hevesy who has discovered and developed news in physics, chemistry, geology, biology and medicine is described. Special attention is given to his work in life science which he had done in the second half of his scientific career and was the base of the development of nuclear medicine. Keywords: George de Hevesy; Radionuclides; Nuclear Medicine Introduction George de Hevesy has founded Radioanalytical Chemistry and Nuclear Medicine, discovered the element hafnium and first separated stable isotopes. He was an inventor in many disciplines and his interest was not only focused on the development and refinement of methods, but also on the structure of matter and its changes: atoms, molecules, cells, organs, plants, animals, men and cosmic objects. He was working under complicated political situation in Europe in the 20th century. During his stay in Germany, Austria, Hungary, Switzerland, Denmark, and Sweden he wrote a lot papers in German. In 1962 he edited a large part of his articles in a collection where German papers are translated in English [1]. -
Contribution to the Historical Development of Macromolecular Chemistry – Exemplified on Cellulose
CELLULOSE CHEMISTRY AND TECHNOLOGY CONTRIBUTION TO THE HISTORICAL DEVELOPMENT OF MACROMOLECULAR CHEMISTRY – EXEMPLIFIED ON CELLULOSE PETER ZUGENMAIER Institute of Physical Chemistry, Clausthal University of Technology, D-38678 Clausthal-Zellerfeld, Germany Dedicated to Professor Elfriede Husemann, on the occasion of her 100th birthday in December 2008. She was an admirable and internationally highly recognized scientist and the first director of the Institute of Macromolecular Chemistry (Hermann-Staudinger-Haus) of the Albert-Ludwigs-Universität Freiburg; the foundation of the institute owing to the eminent scientific success and recognition of the work of Hermann Staudinger, leading to the Nobel Prize in the field of macromolecular chemistry. Received October 20, 2009 The development of the structure determination for cellulose and its derivatives as macromolecules is described from the beginning of the 20th century to the 1940s. The first correct presentation of the constitution of cellulose as a linear chain macromolecule of 1-4 linked β-D-anhydroglucopyranose, with the help of organic chemistry, dates from 1928. The size and shape of cellulose molecules still remained a controversial topic for some time. On the one hand, there were proposals of micelles i.e. aggregates of cyclic mono- or oligoanhydroglucose or micelles of small macromolecules of 30-50 glucose units. On the other hand, cellulose was seen as large macromolecules with more than 3000 glucose units for structures considered in solution as well as in fibres. The final clarification of the cellulose structure as a semi-flexible macromolecule of high molecular weight was extremely hindered by the inadequate interpretation of experimental results. Later, additional experimental and theoretical methods led to a consistent picture of the cellulose structure with high precision. -

To: Sadiq Khan, Mayor of London New London Plan GLA City Hall London Plan Team Post Point 18 London SE1 2AA We welcome the opportunity to comment on the New London Plan and would be grateful if you could confirm receipt of this reponse. About us: The World’s First Planned Cultural Quarter Shared history and mission The Exhibition Road Cultural Group is a partnership of 18 leading cultural and educational organisations in and around Exhibition Road, South Kensington. Together these organisations comprise the world’s first planned cultural quarter, half of which falls within the Knightsbridge Neighbourhood Area. Created from the legacy of the Great Exhibition of 1851, and affectionately known as “Albertopolis”, this cultural quarter was established by the Royal Commission for the Great Exhibition of 1851 for the purpose of “increasing the means of industrial education and extending the influence of science and art upon productive industry”. Across its estate of 87 acres in South Kensington, the Royal Commission established three of the world’s most popular museums: The Natural History Museum, Victoria and Albert Museum, Science Museum and three colleges dedicated to arts, science and design: Imperial College London, the Royal College of Music and Royal College of Art and the most famous concert venue in the world, the Grade l listed Royal Albert Hall which was created originally as the Central Hall of Arts and Sciences. Over past century and a half, these institutions have been joined by other organisations that share the mission of promoting innovation and learning through the arts and science, including the Goethe Institut, Royal Geographical Society, Institute Français and the Ismaili Centre. -

The Value of Vague Ideas in the Development of the Periodic System of Chemical Elements
The Value of Vague Ideas in the Development of the Periodic System of Chemical Elements. Thomas Vogt Departments of Chemistry & Biochemistry and Philosophy University of South Carolina Abstract The exploration of chemical periodicity over the past 250 years led to the development of the Periodic System of Elements and demonstrates the value of vague ideas that ignored early scientific anomalies and instead allowed for extended periods of normal science where new methodologies and concepts are developed. The basic chemical element provides this exploration with direction and explanation and has shown to be a central and historically adaptable concept for a theory of matter far from the reductionist frontier. This is explored in the histories of Prout’s hypothesis, Döbereiner Triads, element inversions necessary when ordering chemical elements by atomic weights, and van den Broeck’s ad-hoc proposal to switch to nuclear charges instead. The development of more accurate methods to determine atomic weights, Rayleigh and Ramsey’s gas separation and analytical techniques, Moseley’s x-ray spectroscopy to identify chemical elements, and more recent accelerator-based cold fusion methods to create new elements at the end of the Periodic Table point to the importance of methodological development complementing conceptual advances. I propose to frame the crossover from physics to chemistry not as a loss of accuracy and precision but as an increased application of vague concepts such as similarity which permit classification. This approach provides epistemic flexibility to adapt to scientific anomalies and the continued growth of chemical compound space and rejects the Procrustean philosophy of reductionist physics. Furthermore, it establishes chemistry with its explanatory and operational autonomy epitomized by the periodic system of elements as a gateway to other experimental sciences.
