Nobel Prize various

One of the essentials of living with the Nobel Prize was to learn to firmly say no. Of the large number of invitations I receive for various... 

C = 12 internationally adopted as the unified atomic weight standard by both chemi.sts and physicists. 6-coordinate carbon established in various carboranes by W. N. Lipscomb and others. (Nobel Prize 1976 for structure and bonding of boranes). 

The remaining actinide elements were prepared by various bombardment techniques fairly regularly over the next 25 years (Table 31.1) though, for reasons of national security, publication of the results was sometimes delayed. The dominant figure in this field has been G. T. Seaborg, of the University of California, Berkeley, in early recognition of which, he and E. M. McMillan were awarded the 1951 Nobel Prize for Chemistry. 

England, and received his D.Sc. from the University of Manchester with William Henry Perkin, Jr. After various academic appointments, he moved in 1930 to Oxford University, where he remained until his retirement in 1955. An accomplished mountain climber, Robinson was instrumental in developing the mechanistic descriptions of reactions that we use today. He received the 1947 Nobel Prize in chemistry. 

Scientists pursue ideas in an ill-defined but effective way called the scientific method, which takes many forms. There is no strict rule of procedure that leads you from a good idea to a Nobel prize or even to a publishable discovery. Some scientists are meticulously careful, others are highly creative. The best scientists are probably both careful and creative. Although there are various scientific methods in use, a typical approach consists of a series of steps (Fig. 6). The first step is often... 

Light absorption is usually quite fast (time scale = 1-10 femtoseconds), and various physical measurements can be used to characterize the properties of intermediates that are formed along the reaction coordinate. This strategy was introduced by Porter who later shared the Nobel Prize in Chemistry with Eigen and Norrish for their germinal contributions to fast reaction kinetics. See Chemical Kinetics...

The high reactivity of di- and trinitrophenyl fluorides towards nucleophiles has been used for the arylation of various N-nucleophiles. A method was developed for the determination of N-terminal amino acids in peptides. Thus, nucleophilic attack of the amino acid nitrogen at Sanger s reagent (2,4-dinitrophenyl fluoride, 4), hydrolysis and subsequent analysis of the N-(2,4-dinitrophenyl)amino acid allows determination of the amino acid.162,163 Although this method has been replaced by more efficient procedures, it marked a milestone in the elucidation of peptide structures (Nobel Prize 1958). A variety of N-nuclcophilcs (no amino acids) which have been used in the nucleophilic substitution of 2,4-dinitrophcnyl fluoride is listed. 

NATTA, GIULIO (1903—1979). An Italian chemist along with Karl Ziegler won the Nobel prize for chemistry in 1963 for his fundamental work on catalytic polymerization. In 1954 he developed isotactic polypropylene at his laboratory at the Polytechnic Institute of Milan, which led to wide application of various stereospecific polymers with organometallic catalysts...
