American chemist

Gabor A. Somorjai (born May 4, 1935) is a professor of chemistry at the University of California, Berkeley, and is a leading researcher in the field of surface chemistry and catalysis, especially the catalytic effects of metal surfaces on gas phase reactions ("heterogeneous catalysis"). For his contributions to the field, Somorjai won the Wolf Prize in Chemistry in 1998, the Linus Pauling Award in 2000, the National Medal of Science in 2002, the Priestley Medal in 2008, the 2010 BBVA Foundation Frontiers of Knowledge Award in Basic Science and the NAS Award in Chemical Sciences in 2013. In April 2015, Somorjai was awarded the American Chemical Society's William H. Nichols Medal.

Somorjai was born in Budapest in 1935 to Jewish parents. He was saved from the Nazis when his mother sought the assistance of Raoul Wallenberg in 1944 who issued Swedish passports to Somorjai's mother, himself and his sister saving them from the Nazi death camps. While Somorjai's father ended up in the camp system, he was fortunate to survive but many of Somorjai's extended family ended up in the camp system. He was studying chemical engineering at the Budapest University of Technology and Economics in 1956. As a participant in the 1956 Hungarian Revolution, Somorjai left Hungary to go to the US after the Soviet invasion. Along with other Hungarian immigrants, Somorjai enrolled in graduate study at Berkeley and obtained his doctorate in 1960. He joined IBM's research staff in Yorktown Heights, New York for a few years but returned to Berkeley as an assistant professor in 1964.

The introduction of new technology such as low energy electron diffraction revolutionised the study of surfaces in the 1950s and 1960s. However, early studies were limited to surfaces such as silicon, important for its electrical properties. In contrast, Somorjai was interested in surfaces such as platinum known for its chemical properties. Somorjai discovered that the defects on surfaces are where catalytic reactions take place. When these defects break, new bonds are formed between atoms leading to complex organic compounds such as naphtha to be converted into gasoline as an example. These findings led to greater understanding of subjects such as adhesion, lubrication, friction and adsorption. His research also has important implications such as nanotechnology. In the 1990s, Somorjai started working with physicist Y. R. Shen on developing a technique known as Sum Frequency Generation Spectroscopy to study surface reactions without the need for a vacuum chamber. He is also studying surface reactions in nanotechnology at the atomic and molecular level using atomic force microscopy and scanning tunnelling microscopy, both of which can be used without vacuum. Somorjai's expertise in surfaces was used as a consultant to the 2002 Winter Olympics where he gave advice on how to make ice skating surfaces as fast as possible. Somorjai's research had shed new light on ice, demonstrating that skaters skated on a top layer of rapidly vibrating molecules, rather than on a layer of liquid water on top of the ice acting as a lubricant, which had previously been the generally accepted explanation for the slipperiness of ice. During his career, Somorjai has published more than one thousand papers and three textbooks on surface chemistry and heterogeneous catalysis. He is now the most often cited person in the fields of surface chemistry and catalysis.
