The Nobel Prize awarded to Professor F. Haber Institute (Berlin) Gerhard Ertl "for pioneering research in the field of surface chemistry." Chemical reactions on the catalyst surface play a decisive role in many industrial plants. surface chemistry explains are many processes - the metal corrosion to ozone depletion (in the latter case, the key step of the reaction can proceed at the surface of small ice crystals in the stratosphere). Semiconductor Manufacturing - another area that depends on the information on the characteristics of surface chemistry. Ertl was one of the first researchers to evaluate the potential of the surface chemistry. Step by step he has developed a methodology for surface chemistry by demonstrating how different experimental procedures allow to obtain a comprehensive picture of the reaction on the surface. Its development laid the scientific basis of modern surface chemistry, his methodology is used both in basic research and in the development of chemical industry products. The approach developed by Ertl, based not only on the results obtained in the study process they Bosch-Haber used in the fixation of atmospheric nitrogen. He also studied the oxidation of carbon monoxide on the platinum surface, the reaction is used for the catalytic purification of automobile exhaust.

Last summer I had a great weekend. Our family: my parents, my sister and I went to sea. We came to him by train. It took us two days. I like my destination. We swam in the sea and walked in the mountains. The weather was beautiful. It rained only once. In the evening we went to the movies or went cycling. Sometimes my sister and I played on the playground with new friends, and parents went to the club to play chess or table tennis. We spent three weeks there. I really like my summer vacation.
