Sammendrag av Hassel Lecture - "The Genius of Michael Faraday"

Lord Rutherford said of Michael Faraday that he was one of the greatest experimenters ever; Albert Einstein believed that Faraday was responsible for the greatest change in the intellectual structure of physics since Newton. There is little doubt that Faraday bequeathed a greater corpus of useful knowledge than any other physical scientist.

How did it come about that Faraday, a deeply religious man who left school at thirteen to become an errand boy and then an apprentice to a bookbinder (a young man who never attended high school or a university and knew no mathematics), could reach such pinnacles? In terms that are intelligible to non-scientists and interested lay persons, the speaker shall endeavour to answer the above and related questions.

The tale of Faraday's achievements and discoveries is one of the most romantic in the history of science; his character, intellect and commitment speak to us through all ages.

Sir John once occupied the chair of chemistry created for Michael Faraday at the Royal Institution of Great Britain, of which he was Director (1986-1991). Formerly he was Head of the Department of Physical Chemistry, University of Cambridge (1978-1996) and Master of Peterhouse (1993-2002). He is now Honorary Professor at the Department of Materials Science and Metallurgy, Cambridge.

 

Ekstraforelesning

Onsdag 19. mai kl. 11.15 i Auditorium 2, Kjemisk institutt, Universitetet i Oslo.

Tittel "Exploring the Interface between Heterogeneous and Homogeneous Catalysis"

Av
Sir John Meurig Thomas
Department of Materials Science and Metallurgy, University of Cambridge

Sammendrag

Recent advances in structural characterization have prompted many students of catalysis to argue that the distinctions between heterogeneous and homogeneous catalysts are becoming increasingly blurred. The situation has further prompted certain investigators to enunciate the following statements, each of which will be adumbrated during the course of the talk:

  • 1. The scope for introducing multifunctional catalysis IS greater with heterogeneous than with homogeneous catalysts.
  • 2. The nature of active sites in homogeneous and heterogeneous catalysts is very different.
  • 3. Certain chemical transformations can be effected efficiently only with heterogeneous catalysts.
  • 4. Many homogeneous catalysts may be immobilized at the surfaces of, or intercalated within, solids and often yield superior performance.
  • 5. Spatially isolated and readily accessible single-sites on supports unite the advantages of heterogeneous and homogeneous catalysts.
