Kay Severin

Kay Severin was born in Germany in 1967. He obtained his Ph.D. in 1995 with a thesis in the group of Prof. W. Beck, University of Munich. Subsequently, he joined the group of Prof. M. R. Ghadiri as a postdoctoral fellow. In 1997, he started independent research projects ("Habilitation") at the Department of Chemistry, University of Munich. In 2001, he became assistant professor at the Institute of Chemical Sciences and Engineering at the Swiss Federal Institute of Technology, Lausanne (EPFL). Since 2009, he is full professor at the same institute. Awards: Bayerischer Habilitations Förderpreis (1997), ADUC award of the year (2001), Heinz Maier-Leibnitz award of the DFG (2001), award of the Karl-Ziegler foundation (2001), Arnold Sommerfeld award of the Bavarian Academy of Science (2001), Werner Prize of The Swiss Chemical Society (2003), Otto Roelen Medal of the DECHEMA (2005), award for chemistry of the Academy of Sciences, Göttingen (2007), Dalton Transactions European Lectureship (2008).

Xile Hu

Xile Hu was born in 1978 in Putian, southeastern China. He entered the Peking University in Beijing in 1996. Besides learning too little chemistry, his biggest regret in the college was not able to correct his southern accent in Mandarin. After graduated from PKU, he went to the United States and began his doctoral studies at the University of California, San Diego. In December 2004, he finished with a Ph.D. in chemistry and some fond memories of the beautiful city of San Diego. He then moved to the Los Angeles area and become a postdoctoral scholar at the California Institute of Technology. There he enjoyed numerous stimulating scientific (and other) discussions with friends and colleagues. He also made plenty of friends outside the campus and was a frequent in many local Chinese restaurants. In 2007, after two pleasant visits to Switzerland, he decided to move across the continent one more time and join the faculty of the École Polytechnique Fédérale de Lausanne (EPFL). He now directs the Laboratory of Inorganic Synthesis and Catalysis and is interested in developing chemistry for synthesis, energy and sustainability.

Rampe à vide

thumb|upright=1.5|Une rampe à vide La rampe à vide est un appareil inventé par Wilhelm Schlenk afin de manipuler et de synthétiser des échantillons sensibles à l'air. Cet appareil comprend une double tubulure - une pour le vide et une pour le gaz inerte. Le vide est créé par une pompe mécanique. Un piège à froid contenant par exemple de l'azote liquide est placé entre cette pompe et la partie principale de la rampe à vide.

Air sensitivity

Air sensitivity is a term used, particularly in chemistry, to denote the reactivity of chemical compounds with some constituent of air. Most often, reactions occur with atmospheric oxygen (O2) or water vapor (H2O), although reactions with the other constituents of air such as carbon monoxide (CO), carbon dioxide (CO2), and nitrogen (N2) are also possible. A variety of air-free techniques have been developed to handle air-sensitive compounds. Two main types of equipment are gloveboxes and Schlenk lines.

Chimie organométallique

La chimie organométallique est l'étude des composés chimiques contenant une liaison covalente entre un métal et un atome de carbone situé dans un groupe organique. Elle combine des aspects de la chimie organique et de la chimie inorganique. 1827 Le sel de Zeise, nommé en l'honneur de William Christopher Zeise, est le premier complexe oléfines/platine. 1863 Charles Friedel et James Crafts préparent un organochlorosilane. 1890 Ludwig Mond découvre le carbonyle de nickel. 1899 Introduction de la réaction de Grignard.

Air-free technique

Air-free techniques refer to a range of manipulations in the chemistry laboratory for the handling of compounds that are air-sensitive. These techniques prevent the compounds from reacting with components of air, usually water and oxygen; less commonly carbon dioxide and nitrogen. A common theme among these techniques is the use of a fine (100–10−3 Torr) or high (10−3–10−6 Torr) vacuum to remove air, and the use of an inert gas: preferably argon, but often nitrogen.

Chimie analytique

La chimie analytique est la partie de la chimie qui concerne l'analyse des produits, c'est-à-dire l'identification et la caractérisation de substances chimiques connues ou non. La substance chimique dont on cherche à déterminer les propriétés est appelée « analyte ». Ses applications vont du suivi de production (vérifier qu'une chaîne fabrique un produit conforme aux spécifications) à l'enquête policière (déterminer la nature d'une trace, la provenance d'une terre, d'une peinture).
