Solving QCD via multi-Regge theory. (open access)

Solving QCD via multi-Regge theory.

To solve QCD at high-energy the authors must simultaneously find the hadronic states and the exchanged pomeron (IP) giving UNITARY scattering amplitudes. Experimentally, the IP {approximately} a Regge pole at small Q{sup 2} and a single gluon at larger Q{sup 2}. (F{sub 2}{sup D}-H1, dijets-ZEUS). In the solution which the author describes, these non-perturbative properties of the IP are directly related to the non-perturbative confinement and chiral symmetry breaking properties of hadrons.

Microscale chemistry technology exchange at Argonne National Laboratory - east. (open access)

Microscale chemistry technology exchange at Argonne National Laboratory - east.

The Division of Educational Programs (DEP) at Argonne National Laboratory-East interacts with the education community at all levels to improve science and mathematics education and to provide resources to instructors of science and mathematics. DEP conducts a wide range of educational programs and has established an enormous audience of teachers, both in the Chicago area and nationally. DEP has brought microscale chemistry to the attention of this huge audience. This effort has been supported by the U.S. Department of Energy through the Environmental Management Operations organization within Argonne. Microscale chemistry is a teaching methodology wherein laboratory chemistry training is provided to students while utilizing very small amounts of reagents and correspondingly small apparatus. The techniques enable a school to reduce significantly the cost of reagents, the cost of waste disposal and the dangers associated with the manipulation of chemicals. The cost reductions are achieved while still providing the students with the hands-on laboratory experience that is vital to students who might choose to pursue careers in the sciences. Many universities and colleges have already begun to switch from macroscale to microscale chemistry in their educational laboratories. The introduction of these techniques at the secondary education level will lead to freshman …

Nucleation of nanocrystalline diamond by fragmentation of fullerene precursors. (open access)

Nucleation of nanocrystalline diamond by fragmentation of fullerene precursors.

Growth of diamond films from C{sub 60}/Ar microwave discharges results in a nanocrystalline microstructure with crystallite sizes in the range 3-10 nm. Heterogeneous nucleation rates of 10{sup 10} cm{sup {minus}2} sec are required to account for the results. The nucleation mechanism presented here fulfills this requirement and is based on the insertion of carbon dimer, C{sub 2}, molecules, produced by fragmentation of C{sub 60}, into the n-bonded dimer rows of the reconstructed (100) surface of diamond. Density functional theory is used to calculate the energetic of C{sub 2} insertion into carbon clusters that model the (100) surface. The reaction of singlet C{sub 2} with the double bond of the C{sub 9}H{sub 12} cluster leads to either carbene structures or a cyclobutynelike structure. At the HF/6-31G* level, the carbene product has a C{sub 2v} structure, while at the B3LYP/6-31G* levels of theory, it has a C{sub s} structure with the inserted C{sub 2} tilted. No barrier for insertion into the C=C double bond of the C{sub 9}H{sub 12} cluster was found at the HF/6-31G* and B3LYP/6-31G* levels of theory. Thus, calculations including correlation energy and geometry optimization indicate that insertion of C{sub 2} into a C=C double bond leads to a …

Student's sought for new art grant

A newspaper clipping published in The North Texas Daily, with the headline "Student's sought for new art grant," written by Julie Freeman. A grant for $600,000 from the Edward and Betty Marcus Foundation will provide stipends for fifteen NT graduate students studying art education during the next three years. The grant will continue paying for the NT's Marcus Fellows Program until August 2001. The purpose of the fellowship is to allow graduate students to develop innovative ways to teach art and art appreciation.

Crustal structure of China and adjacent areas: a final report of the detailed compilation of data and results

In geophysical terms, China is a ''data rich'' country. However it is often very difficult for Western scientists to access the available information or identify individuals responsible for program development. The USGS has largely bypassed this bottleneck by virtue of more than two decades of collaborative research based on an official Protocol Agreement.
