Presentation Speech by Professor A. Fredga, member of the Nobel Committee for Chemistry of Your Majesties, Royal Highnesses, Ladies and Gentlemen. With this year’s Nobel Prize for Chemistry, the Academy of Sciences wished to signalize the discovery and development of diene synthesis. This achievement falls within the domain of classical organic chemistry- the chemistry of…

18 October 1982 has decided to award the 1982 Nobel Prize for chemistry to Ph.D. Aaron Klug, MRC Laboratory of Molecular Biology, Cambridge, England, for his development of crystallographic electron microscopy and his structural elucidation of biologically important nucleic acid-protein complexes. DEPICTING THE BUILDING BLOCKS OF LIFE Life is a chemical phenomenon. Living organisms are…

Building complex chemicals from their simplest components in the laboratory relies on the tools available for the task, and for chemists these tools are the repertoire of reactions they have at hand. Using these reactions, synthetic organic chemists act as chemical construction engineers, gradually piecing together the correct molecules in the correct manner until the…

English Presentation Speech by Professor Sven Lidin, Member of the ; Member of the Nobel Committee for Chemistry, 10 December 2011 Your Majesties, Your Royal Highnesses, Ladies and Gentlemen, For three millennia we have known that five-fold symmetry is incompatible with periodicity, and for almost three centuries we believed that periodicity was a prerequisite for…

  Walter Kohn showed in 1964-65 that the energy of a quantum-mechanical system is uniquely determined by its electron density. This quantity is more easily handled than the complicated wave function in the Schrödinger equation. Kohn also provided a method which made it possible to set up equations whose solutions give the system’s electron density…

Swedish Presentationstal av Professor Sven Lidin, ledamot av ; ledamot av Nobelkommittén för kemi, 10 December 2011 Eders Majestäter, Eders Kungliga Högheter, Mina damer och herrar. Unders tre årtusenden har vi vetat att femtalig symmetri inte går att kombinera med periodicitet, och under närmare tre sekler har vi trott att periodicitet är en förutsättning för…
