  1. NobelLaureates in Chemistry Amr Tawfik, Mosatafa Hawary 4th year, 2nd year, Faculty of Pharmacy Alexandria University Noble Laureates In Chemistry – Amr Tawik & Moustafa Hawary

  2. Nobel laureates in chemistry Famous Nobel laureates in chemistry since 1901 Nobel laureates attended Biovision Bibliotheca Alexandrina An Egyptian Nobel laureates Gerhard Ertl: Modern surface chemistry

  3. 1901 Jacobus van 't Hoff in recognition of the extraordinary services he has rendered by the discovery of the laws of chemical dynamics and osmotic pressure in solutions

  4. August Arrhenius 1903 in recognition of the extraordinary services he has rendered to the advancement of chemistry by his electrolytic theory of dissociation

  5. 1908 alpha, beta, and gamma rays He demonstrated radioactivity and the spontaneous disintegration of atoms the first person to artificially disintegrate an element Ernest Rutherford

  6. Marie Curie 1911 Marie Curie pioneered radioactivity research. Only person to win the award in two different sciences. The first woman to win a Nobel Prize. Marie Curie was the first female professor at the Sorbonne.

  7. Walther Nernst 1920 in recognition of his work in thermo chemistry

  8. Hans Fischer 1930 constitution of haemin and chlorophyll and especially for his synthesis of haemin

  9. Sir Robert Robinson 1947 for his investigations on plant products of biological importance, especially the alkaloids

  10. Gerhard Herzberg 1971 for his contributions to the knowledge of electronic structure and geometry of molecules, particularly free radicals.

  11. Jean Marie Lean 1987 With Donald J.Cram and Charles J.Pedersen for their development and use of molecules with structure-specific interactions of high selectivity.

  12. F. Sherwood Rowland 1995 Paul J. Crutzen and Mario J. Molina for their work in atmospheric chemistry, particularly concerning the formation and decomposition of ozone

  13. Ryoji Noyori 2001 With William S. Knowles and K. Barry Sharpless for their work on chirally catalysed hydrogenation reactions

  14. Peter Agre 2003 With Roderick MacKinnon for discoveries concerning channels in cell membranes for the discovery of water channels"

  15. Ahmed H. Zewail 1999 for his studies of the transition states of chemical reactions using femtosecond spectroscopy

  16. The King of Femtoland

  17. Ahmed H. Zewail Ahmed Zewail receiving his Nobel Prize from His Majesty the King at the Stockholm Concert Hall 1999.

  18. VOYAGE THROUGH TIMEWalks of Life to the Nobel Prize Ahmed H. Zewail Zewail is the first scientist from the Arab world to ever receive the Nobel Prize, and the only living scientist from the entire Islamic World of more than one billion people so honored

  19. Gerhard Ertl 2007 for his studies of chemical processes on solid surfaces

  20. Gerhard Ertl a gold medal a diploma 10 million Swedish kronor his 71st birthday

  21. catalytic cleaning carbon monoxide oxidates on platinum electronics industry to manufacture semiconductor materials for components Freons reduce the ozone layer by reacting on the surfaces of small ice crystals, artificial fertilizers contain ammonia which is produced when nitrogen and hydrogen react on an iron surface rusting takes place when an iron surface is exposed to oxygen renewable fuels can be produced using catalytic surfaces

  22. The emergence of modern surface chemistry The first to understand the potential of new technology Methodological foundations for an entire field of research High vacuum system and use of different technologies

  23. Modern surface chemistry Behavior of hydrogen on metal surfaces - Produced in solar cells -catalysis Nitrogen becomes an artificial fertilizer - Haber-Bosch process

  24. The Haber-Bosch process step-by-step

  25. Surface measurement difficulties Distinguish atomic/ molecular nitrogen Spectroscopic methods Photons or free electrons - type of atoms - chemical environment Structure of the surface

  26. Nitrogen split takes longest Adding potassium Nitrogen split ammonia formation

  27. Modern surface chemistry Method and values of rates and activation energies for each step of the reaction Exhaust cleaning oxidation of Co on platinum
