Christopher studies

The mechanisms by which nucleophilic substitution takes place have been the subject of much study Extensive research by Sir Christopher Ingold and Edward D Hughes and their associates at University College London during the 1930s emphasized kinetic and stereochemical measurements to probe the mechanisms of these reactions... [Pg.330]

Before beginning a detailed discussion of alkene reactions, let s review briefly some conclusions from the previous chapter. We said in Section 5.5 that alkenes behave as nucleophiles (Lewis bases) in polar reactions. The carbon-carbon double bond is electron-rich and can donate a pair of electrons to an electrophile (Lewis acid), for example, reaction of 2-methylpropene with HBr yields 2-bromo-2-methylpropane. A careful study of this and similar reactions by Christopher Ingold and others in the 1930s led to the generally accepted mechanism shown in Figure 6.7 for electrophilic addition reactions. [Pg.188]

The author thanks Stefan Vogtner for numerical studies of expansions of 1/r in a Gaussian basis which have challenged the present analytic investigation. Discussions with Christoph van Wiillen and Wim Klopper on this subject have been very helpful. [Pg.88]

Moore (1998) suggested that the data available could be interpreted in terms of an ice crust 10-15 km thick. Christopher Chyba from the SETI Institute (Mountain View, California) has published articles in Nature (2000), the Proceedings of the National Academy of Sciences (2001a) and in Science (2001b) in which he suggests that a detailed study of this Jovian moon is necessary he discusses the possibility of a complex ecosystem, nourished by the radiation coming from outer space, on or in the ice layers of the moon. The planned Europa orbiter mission may provide certainty on this, but at least another five years of uncertainty lie ahead. The use of a submersible robot to study the (possible) ocean layer and its floor has been discussed. [Pg.51]

Christoph Hengst was born in Giefien in 1978. He studied chemistry at the Philipps-University in Marburg and is currently a Ph.D. student working in the group of Prof. Hilt in the field of cobalt-initialized multicomponent reactions. [Pg.366]

Dr Christopher Yang is a researcher at the Institute of Transportation Studies at the University of California, Davis. He is a co-leader of Infrastructure Systems Analysis within the Sustainable Transportation Energy Pathways (STEPS) Program and his work focuses mainly on the analysis of hydrogen infrastructure, the grid impacts of electric vehicle charging and the reduction of greenhouse-gas emissions from transportation systems. [Pg.660]

Letter from Christopher Ingold to Prevost, dated 29 July 1946 and a letter from the Secretary of the Nobel Committees of the Swedish Royal Academy of Sciences to Prevost, dated 16 January 16 1954. Copies of these letters were given to me by Constantin Georgoulis, who completed a doctoral dissertation at Paris in 1960 on the kinetic study of reaction schemas for allylic transpositions, under the direction of Prevost. Another of Georgoulis s teachers was Paul Job, cousin of Andre Job. [Pg.177]

Lisa E. Cooper was born and raised in Renton, Washington. She received a B.S. in Biochemistry in 2004 from Western Washington University under the guidance of Professor Christopher J. A. Daley. Subsequently, she joined the laboratory of Professor Wilfred A. van der Donk at the University of Illinois at Urbana-Champaign, where she studied lantibiotic biosynthetic enzymes. After successfully engineering an in vitro production system for the novel two-component lantibiotic haloduracin, she characterized the structural features essential for the activity of this antibiotic. [Pg.255]

In 1707 Nicolas Lemery published his famous Treatise on Antimony. He was born at Rouen on November 17, 1645. After studying pharmacy there under one of his relatives, he went to Paris in 1666 to complete his education. Dissatisfied with his progress under the unsociable but scholarly Christophe Glaser, demonstrator of chemistry at die Jardin du Roi, he resolved to tour France and leam firsthand from the greatest chemists of his day (43). Dr. Clara DeMilt believed however that lAmery gained many of the ideas presented in his textbook from... [Pg.99]

Christopher Hardacre read natural sciences at the University of Cambridge, where he also obtained his PhD in 1994. He was appointed to a lectureship in physical chemistry at the Queen s University of Belfast in 1995 and in 2003, he became a professor of physical chemistry. He is currently director of research in CenTACat, and his current interests include the understanding of gas and liquid phase catalytic processes for emission control, clean energy production, and fine chemical synthesis as well as the study and use of ionic liquids. [Pg.404]

Wu, Li-Tzy, Christopher L. Ringwalt, Paolo Mannelli, and Ashwin A. Pat-kar. Prescription Pain Reliever Abuse and Dependence among Adolescents A Nationally Representative Study. Journal of the American Academy of Child and Adolescent Psychiatry 47, no. 9 (September 2008) 1,020-1,029. According to the results of this study, 7 percent of youth ages 12 to 17 reported nonprescription use of prescription pain relievers and 1 percent met criteria for abuse or dependence on the prescription pain relievers. Although the results depend on potentially biased self-reports from youth, the reliance on a representative national sample allows the results to be generalized widely. [Pg.202]
