Toward Unraveling the Photochemistry of TATB

Description: A combined theoretical and experimental chemical analysis has been conducted to unravel the mechanism underlying the color change of yellow TATB (1,3,5 triamino-trinitro-benzene) to green upon UV irradiation. There is strong evidence to conclude that the process is photochemical in nature and due to the formation of the mono nitroso derivative. They have identified a chemical synthesis by which this derivative compound can be produced in the laboratory, thus allowing for direct testing and dete… more

Uncertainty Propagation in Calibration of Parallel Kinematic Machines

Description: Over the last decade, multi-axis machine tools and robots based on parallel kinematic mechanisms (PKMs) have been developed and marketed worldwide. Positional accuracy in these machines is controlled by accurate knowledge of the kinematic parameters which consists of the joint center locations and distances between joint pairs. Since these machines tend to be rather large in size, the kinematic parameters (joint center locations, and initial strut lengths) are difficult to determine when these … more

HTS wire irradiation test with 8 GeV protons

Description: The radiation level at High Energy Particle Accelerators (HEPA) is relatively high. Any active component which should be close to the accelerator has to be radiation hard. Since High Temperature Superconductors (HTS) have a great potential to be used in HEPAs (e.g., in superconducting magnets, current leads, RF cavities), it is important to understand the radiation hardness of these materials. A radiation test of HTS wire (Bi-2223) was performed at Fermilab. The HTS sample was irradiated with 8… more

Steps towards universality of the Chemical Weapons Convention: How can Africa contribute?

Description: Universality is a fundamental principal of the Chemical Weapons Convention (CWC). It suffuses the fabric of the Convention, found not only in the very first ringing clauses of Article I, but also in the many technical details of its Annexes and Schedules. Consequently, universality is a topic on which commentary is appropriate from all quarters. The author offers his personal views as a lawyer on this important matter in the hope that, this distinguished audience may gain a perspective not avai… more

Effect of focusing optics on x-ray speckle contrast

Description: The authors investigated the behavior of speckle contrast and size under various experimental conditions using 1.82 keV x-rays. In this paper, they report the comparison of two different setups for x-ray speckle experiments: one employing a focusing zone plate and one in which a pinhole selects the size of the coherent x-ray beam. They found a strong dependence of the speckle contrast and size on the type of setup. In general, the pinhole setup results in higher contrast but smaller speckle siz… more

Polymeric Carbon Dioxide

Description: Synthesis of polymeric carbon dioxide has long been of interest to many chemists and materials scientists. Very recently we discovered the polymeric phase of carbon dioxide (called CO{sub 2}-V) at high pressures and temperatures. Our optical and x-ray results indicate that CO{sub 2}-V is optically non-linear, generating the second harmonic of Nd: YLF laser at 527 nm and is also likely superhard similar to cubic-boron nitride or diamond. CO{sub 2}-V is made of CO{sub 4} tetrahedra, analogous to … more

Hydrogen absorption in epitaxial W/Nb(001) and polycrystalline Fe/Nb(110) multilayers studied in-situ by X-ray/neutron scattering techniques and X-ray absorption spectroscopy

Description: Hydrogen can be absorbed in large quantities by 100 {angstrom} thin Nb layers embedded in epitaxial W/Nb and polycrystalline Fe/Nb multilayers. The solubility and the hydrogen-induced structural changes of the host lattice are explored in-situ by small-angle neutron/X-ray reflectometry and high-angle diffraction. These measurements reveal for both systems that the relative out-of-plane expansion of the Nb layers is considerably larger than the relative increase of the Nb interplanar spacing ind… more

Initiation in H{sub 2}/O{sub 2}: Rate constants for H{sub 2} + O{sub 2} {yields} H + HO{sub 2} at high temperature

Description: The reaction between H{sub 2} and O{sub 2} has been studied in a reflected shock tube apparatus between 1662--2097 K. O-atom atomic resonance absorption spectrometry (ARAS) was used to observe absolute [O]{sub t} under conditions of low [H{sub 2}]{sub 0} so that most secondary reactions were negligible. Hence, the observed [O]{sub t}, was the direct result of the rate controlling reaction between H{sub 2} and O{sub 2}. Three different reactions were considered, but experimental and ab initio th… more

Assessing economic impacts of clean diesel engines. Phase 1 report: U.S.- or foreign-produced clean diesel engines for selected light trucks

Description: Light trucks' share of the US light vehicle market rose from 20% in 1980 to 41% in 1996. By 1996, annual energy consumption for light trucks was 6.0 x 10{sup 15} Btu (quadrillion Btu, or quad), compared with 7.9 quad for cars. Gasoline engines, used in almost 99% of light trucks, do not meet the Corporate Average Fuel Economy (CAFE) standards. These engines have poor fuel economy, many getting only 10--12 miles per gallon. Diesel engines, despite their much better fuel economy, had not been pre… more
