Mexico-U.S. Relations: Issues for the 106th Congress

Description: SUMMARY The United States and Mexico have a special relationship under the North American Free Trade Agreement (NAFTA), which removes trade and investment barriers between the countries. The relationship has been strengthened by presidential visits, including President Clinton's February 1999 trip to Mexico and President Zedillo's upcoming May 23 trip to Washington, and by regular contacts between cabinet-level officials. Major issues of concern to Congress are trade, immigration, drug traffick… more

Design and performance of nitride-based ultraviolet (UV) LEDs

Description: The authors overview several of the challenges in achieving high efficiency nitride-based UV (< 400 nm) LEDs. The issue of optical efficiency is presented through temperature-dependent photoluminescence studies of various UV active regions. These studies demonstrate enhanced optical efficiencies for active regions with In-containing alloys (InGaN, AlInGaN). The authors compare the performance of two distinct UV LED structures. GaN/AlGaN quantum well LEDs with {lambda} < 360 nm emission ha… more

Specific PVMaT R&D on Siemens Cz silicon product manufacturing: Annual Subcontract Report, June 1998 -- June 1999

Description: This report describes work done by Siemens Solar Industries (SSI) from June 1998 to June 1999 during Phase 1 of a three-phase Photovoltaic Manufacturing Technology (PVMaT 5A2) subcontract from DOE/NREL. The work focuses on improvements in the cost per watt of Cz modules and improved PV module manufacturing technology. The first step toward reducing cost was to reduce wafer thickness. The approach has been a two-step reduction in thickness, from 385 microns to 250 micron cells, and then from 250… more

Demonstration of highly efficient waveguiding in a photonic crystal slab at x=1.5{micro}m wavelengths

Description: Highly efficient transmission of 1.5 {micro}m light in a two-dimensional (2D) photonic crystal slab waveguide is experimentally demonstrated. The light wave is shown to be guided along a triple-line defect formed within a 2D crystal and vertically by a strong index-guiding mechanism. At certain wavelength ranges, a complete transmission is observed, suggesting a lossless guiding along this photonic 1D conduction channel.

Real-space and energy representations for the interface roughness scattering in quantum-well structures

Description: The authors show that the real space representation of the interface-roughness as a fluctuating potential in the coordinate space is equivalent to the usual energy-fluctuation representation for intrasublevel scattering in a single quantum well with a generally shaped confinement-potential profile. The coordinate picture is, however, more general and can be used for higher-order effects and multi-sublevel scattering in coupled multi-quantum-well structures.

Effect of morphology of hydrophobic surfaces on cavitation kinetics

Description: Cavitation has been suggested to be a possible source of long range interactions between mesoscopic hydrophobic surfaces. While evaporation is predicted by thermodynamics, little is known about its kinetics. Glauber dynamics Monte Carlo simulations of a lattice gas close to liquid-gas coexistence and confined between partially drying surfaces are used to model the effect of water confinement on the dynamics of surface-induced phase transition. Specifically, they examine how kinetics of induced … more

Integrated experimental and computational methods for structure determination and characterization of a new, highly stable cesium silicotitanate phase, Cs{sub 2}TiSi{sub 6}O{sub 15} (SNL-A)

Description: Exploratory hydrothermal synthesis in the system Cs{sub 2}O-SiO{sub 2}-TiO{sub 2}-H{sub 2}O has produced a new polymorph of Cs{sub 2}TiSi{sub 6}O{sub 15} (SNL-A) whose structure was determined using a combination of experimental and theoretical techniques ({sup 29}Si and {sup 133}Cs NMR, X-ray Rietveld refinement, and Density Functional Theory). SNL-A crystallizes in the monoclinic space-group Cc with unit cell parameters: a = 12.998(2) {angstrom}, b = 7.5014(3) {angstrom}, c = 15.156(3) {angst… more

Supercritical carbon dioxide-soluble ligands for extracting actinide metal ions from porous solids (EMSP Project Number 64965)

Description: The objective of this project is to develop novel, substituted diphosphonic acid ligands that can be used for supercritical carbon dioxide extraction (SCDE) of actinide ions from solid wastes. Specifically, selected diphosphonic acids, which are known to form extremely stable complexes with actinides in aqueous and organic solution, are to be rendered carbon dioxide-soluble by the introduction of appropriate alkyl- or silicon-containing substituents. The metal complexation chemistry of these ne… more

UTILIZATION OF LIGHTWEIGHT MATERIALS MADE FROM COAL GASIFICATION SLAGS

Description: The integrated-gasification combined-cycle (IGCC) process is an emerging technology that utilizes coal for power generation and production of chemical feedstocks. However, the process generates large amounts of solid waste, consisting of vitrified ash (slag) and some unconverted carbon. In previous projects, Praxis investigated the utilization of ''as-generated'' slags for a wide variety of applications in road construction, cement and concrete production, agricultural applications, and as a la… more

STAR: The Secure Tranportable Autonomous Reactor system, Encapsulated Fission Heat Source. Progress report for period terminating March 31, 2000

Description: Significant progress has been made since the beginning of this project, in September 1999. Part of the project findings are described in References 1 and 2. So far we have found no ''show-stopper''. In fact, based on the findings accumulated so far it appears to us that the Encapsulated Nuclear Heat Source (ENHS) is technologically feasible and looks even more attractive than initially conceived.
