Daniel „Dan“ Shechtman (* 24. Januar 1941 in Tel Aviv) ist ein jüdischer, israelischer Physiker. 2011 wurde ihm der Nobelpreis für Chemie für die Entdeckung der Quasikristalle zugesprochen.

Nach seiner Doktorarbeit arbeitete Dan Shechtman als NRCFellow in den Forschungslaboren der Wright-Patterson Air Force Base in Ohio.

Während seines dreijährigen Forschungsaufenthaltes beschäftigte er sich mit der Mikrostruktur und den physikalisch-metallurgischen Eigenschaften von Titan-Aluminiden.

Ab 1975 arbeitete er am Institut für Materialwissenschaften der Technischen Universität Technion in Haifa, Israel. Von 1981 bis 1983 arbeitete er im Rahmen eines Sabbaticals an der Johns Hopkins University mit sich rasch verfestigenden Aluminium-Metall-Legierungen und entdeckte dort die sogenannte ikosaedrische Phase, die das neue Forschungsgebiet der quasiperiodischen Kristalle eröffnete.

Dan Shechtman ist Professor am Technion und forscht am Louis Edelstein Center und am Wolfson Centre, dem er vorsteht. Seit vielen Jahren fördert er Unternehmensgründungen von Absolventen des Technion, indem er Unternehmer zu Vorträgen dort einlädt.

Dan Shechtman (Hebrew: דן שכטמן) (born January 24, 1941 in Tel Aviv) is the Philip Tobias Professor of Materials Science at the Technion – Israel Institute of Technology, an Associate of the US Department of Energy’s Ames Laboratory, and Professor of Materials Science at Iowa State University. On April 8, 1982, while on sabbatical at the U.S. National Bureau of Standards in Washington, D.C., Shechtman discovered the icosahedral phase, which opened the new field of quasiperiodic crystals. He was awarded the 2011 Nobel Prize in Chemistry for „the discovery of quasicrystals“

After receiving his Ph.D. in Materials Engineering from the Technion in 1972, where he also obtained his B.Sc. in Mechanical Engineering in 1966 and M.Sc. in Materials Engineering in 1968, Prof. Shechtman was an NRC fellow at the Aerospace Research Laboratories at Wright Patterson AFB, Ohio, where he studied for three years the microstructure and physical metallurgy of titanium aluminides. In 1975 he joined the department of materials engineering at Technion. In 1981–1983 he was on Sabbatical at Johns Hopkins University, where he studied rapidly solidified aluminum transition metal alloys, in a joint program with NBS. During this study he discovered the Icosahedral Phase which opened the new field of quasiperiodic crystals. Shechtman experienced several years of hostility toward his non-periodic interpretation (no less a figure than Linus Pauling said he was „talking nonsense“ and „There is no such thing as quasicrystals, only quasi-scientists.“) before others began to confirm and accept it.

Shechtman’s Nobel Prize’s winning work was in the area of quasicrystals, ordered crystalline materials lacking repeating structures, such as this Ag-Al alloy.

Through Shechtman’s discovery, several other groups were able to form similar quasicrystals, finding these materials to have low thermal and electrical conductivity, while possessing high structural stability. Quasicrystals have also been found naturally. Quasicrystalline materials could be used in a large number of applications, including the formation of durable steel used for fine instrumentation, and non-stick insulation for electrical wires and cooking equipment. For this discovery, Shechtman was awarded the Nobel Prize in Chemistry in 2011.

In 1992–1994 he was on sabbatical at National Institute of Standards and Technology, where he studied the effect of the defect structure of CVD diamond on its growth and properties. Prof. Shechtman’s Technion research is conducted in the Louis Edelstein Center, and in the Wolfson Centre which is headed by him. He served on several Technion Senate Committees and headed one of them.

Shechtman joined the Iowa State faculty in 2004. He currently spends about five months a year inAmes on a part-time appointment.

Dan Shechtman is married to Prof. Tzipora Shechtman, Head of the Department of Counseling and Human Development at Haifa University, and author of two books on psychotherapy. They have a son Yoav Shechtman (a PhD student in physics) and three daughters: Tamar Finkelstein (an orthodontist at Tel Aviv University), Ella Shechtman-Cory (a PhD in clinical psychology), and Ruth Dougoud-Nevo (also a PhD in clinical psychology).
