Extractions: Institute of Nuclear Chemistry Director: Dr. Giancarlo Angelini The scientific activities, carried out by of the Institute of Nuclear Chemistry, are related to the use of radiochemical techniques applied to synthetic and organic physical-chemistry problems. In particular, they can be summarized as follows: A) Gas and condensed phase reactivity studies of positive and negative ions formed by radiolytic, nuclear decay and mass spectrometric methods. Classical and no-classic ions can be generated by these methods and their reactivities toward neutral molecules can be evaluated. Particular attentions are devoted to the comprehension of the intramolecular isomerization processes which can take place in the primary ions or in the secondary intermediates. B) Reactivity studies in condensed phase using excited radicalic and ionic species formed by radiolysis, photolysis and nuclear decay methods. Using inclusion compounds (host-guest structure), some valid models are defined to study the reactivity in the solid state and its intrinsic energy transfers. Besides, another interesting field concerns the study of the radiation effects toward the formation and reactivity processes of polycyclic aromatic compounds. With the same technology can be evaluated the isomerization of some terpenic compounds and the dissociation processes of several preservative products used in pharmaceutical field.
Lawrence And His Laboratory: Chapter 7: The End Of The Beginning
A machine that has proven even more productive for nuclear chemistry, the 88inchsector-focused cyclotron, was authorized in 1958 and completed in 1961.

Extractions: CHAPTER 7 The End of the Beginning I n the spring of 1958 Lawrence suffered a serious recurrence of his chronic colitis. Although already failing, he accepted against advice and as his duty President Eisenhower's request that he serve as a technical expert in talks with the Soviet Union toward a ban on testing nuclear weapons. Briefings in Washington and the journey to Geneva proved too much. He was rushed back to a hospital at Stanford, where he died on August 27. His passing ended an era in the Laboratory's history. His confidence and extravagance, enthusiasm and ingenuity, energy and entrepreneurship, could not be duplicated. Nor perhaps would his way have fit the future as well as it had the past. Events in the 1960s would call into question the values he held dear science, technology, industry, growth, and patriotism; and changes in national priorities would shift the center of gravity of the Laboratory's work. The Time Projection Chamber (TPC), shown with inventor David Nygren (left), was designed by LBL physicists for use at PEP, the positron- electron colliding beam ring at Stanford. As Lawrence's successor the University chose Nobel laureate Edwin McMillan , a leader in high-energy physics and accelerator design and associate director for the Physics Division. McMillan served until 1973, when the Lawrence Berkeley Laboratory had become a collection of interdisciplinary groups working in fields as diverse as metallurgy, catalysis and surface science, electron microscopy, theoretical chemistry, photoelectron spectroscopy, earth sciences, hydrology, physical chemistry, cellular biology, oncology, and laser chemistry and biology.

Extractions: By Hao Zhang Charges of Elemental Components Of the three elemental components, a proton has a positive charge, a neutron has a neutral charge, and the electron has a negative charge. Atomic Definitions The atomic number (designated by the symbol Z ) represents the number of protons in the nucleus. In an element, which never has a charge, the number of protons equals the number of electrons. The mass number A ) is the sum of neutrons and protons in the nucleus. Therefore, A Z equals the number of neutrons in a nucleus. Typical Nuclide(where X equals any element): Two Types of Atomic Stability Kinetic stability - the likelihood of a nucleus to change into a more stable state. Thermodynamic stability - A comparison of the potential energy of the nucleus to the sum of the potential energy of its protons and neutrons.

Extractions: Nuclear Chemistry at Oregon State University Professor Walter Loveland is primarily interested in the study of nucleus-nucleus collisions at low, intermediate, and high energies. The long term goals of his nuclear chemistry research group are: (a) searching for new phenomena at the limits of nuclear stability. (b)studying the dynamics and thermodynamics of colliding nuclei. (c)application of nuclear techniques to the study of environmental and/or biomedical problems. In studying the interactions of very energetic heavy colliding nuclei, he is probing conditions which have prevailed only in the very early moments of the universe A typical experiment involves irradiating a metal foil with a heavy ion beam from a particle accelerator and detecting the reaction products recoiling from the target at various angles with large detector arrays. The multiparameter data are recorded on magnetic tape for immediate, on-line analysis and later off-line analysis. Experiments generally involve international collaborations and take place at accelerator complexes in Europe and the U.S. Measurements are made at the accelerator with computer-aided data analysis taking place at OSU. Recent accomplishments of the Loveland group involve the study of fusion reactions with radioactive beams and the generation of several new nuclei by fission and fragmentation of heavy nuclei; and participation in the first synthesis of elements 116 and 118.

For you, we have put together the following brief introductions: Karl-Ludwig Kratz Kratz started his scientific activities in Nuclear Chemistry and Nuclear Structure Physics. Later, he concentrated on nuclear structure data for Nuclear Astrophysics and initated his own research program in Nuclear Astrophysics, with the main focus on the r-process. He also leads a very active group engaged in Environmental Physics, mainly using neutron activation. He was awarded the American Chemical Society Award in Nuclear Chemistry in 1999. In his scarce leisure time he enjoys skiing. Claus Rolfs His scientfic interests lie in the fields of Nuclear Astrophysics and of Materials Science where he has published numerous articles. His textbook on Nuclear Astrophysics, "Cauldrons in the Cosmos", as well as television appearances have helped to make Physics more popular. International awards of his career include the Roentgen Prize of Giessen University and the Humboldt Award of the Belgian-German Scientific Society. Last but not least, Claus Rolfs is an enthusiastic musician.

Extractions: March 28, 2000 Brookhaven Lab Scientist Wins American Chemical Society Award UPTON, NY - The American Chemical Society (ACS) has named Richard L. Hahn, a senior scientist at the U.S. Department of Energy's Brookhaven National Laboratory, the winner of the 2000 ACS Nuclear Chemistry Award. He will receive a citation certificate and a $3,000 award during a March 28 ceremony at the ACS meeting being held this week in San Francisco. The Nuclear Chemistry Award was established in 1955 and is given annually by the ACS to recognize outstanding scientific achievement in the field. Hahn's citation is for "His leadership role in experiments for the detection and measurement of solar neutrinos, for wide-ranging investigations of chemical and nuclear properties of the heaviest elements, and for numerous nuclear reaction and spectroscopy studies." Hahn is the fifth Brookhaven scientist to win the award. Prior to Hahn, the most recent Brookhaven awardee was Raymond Davis, in 1979, for his work with solar neutrinos. "I am very pleased that the members of the ACS award selection committee, my peers in the nuclear chemistry community, thought my research accomplishments were worthy of this honor, especially my studies at Brookhaven during the past 13 years," said Hahn. "Basic research in solar neutrinos is on the cutting edge of science, bringing together people from a variety of fields, physicists and chemists, experimenters and theorists, to determine if our present theories have to be recast to explain all the observed properties of neutrinos."

Under the direction of Guy Berry Krzysztof Matyjaszewski Richard McCullough Gary Patterson and Lynn Walker , current research focuses on broadening the versatility of controlled polymerizations and conducting polymers, both with profound technological implications. For example, Matyjaszewski group interacts with over 10 international chemical companies through the Controlled Polymerization Consortium and Center for Macromolecular Engineering to prepare new advanced materials by radical polymerization. The use of light scattering methods and other means to characterize molecular structure and the dynamics of macromolecules supports sophisticated studies of structure-property relationships.
