A General Initial Decomposition Reaction for Complex Metal Hydrides
The initial thermally activated decomposition of several complex metal hydride compounds, to a binary alkali or alkaline hydride and a group IIIb metal hydride, appears to share a first step in their decomposition mechanisms. The application of this initial thermochemical decomposition step to several alanate compounds illustrates the generality of this approach. For LiAlH4, the decomposition data fall on the derived distribution plot calculated for NaAlH4.

Implementing the Conservation Security Program
This report discusses the Conservation Security Program (CSP), which is a agricultural conservation program created in the 2002 farm bill (P.L. 107-171, §2001). It provides incentives for farmers to pursue conservation and helps pay for conservation practices. Unlike some other NRCS programs, it pays for conservation on land that remains in production and makes eligible a wide range of farm lands (cropland, pastureland, rangeland, grassland, prairie land, tribal lands, and forested lands incidental to an agricultural operation)

Initial scientific uses of coherent synchrotron radiation inelectron storage rings
The production of stable, high power, coherent synchrotron radiation at sub-terahertz frequency at the electron storage ring BESSY opens a new region in the electromagnetic spectrum to explore physical properties of materials. Just as conventional synchrotron radiation has been a boon to x-ray science, coherent synchrotron radiation may lead to many new innovations and discoveries in THz physics. With this new accelerator-based radiation source we have been able to extend traditional infrared measurements down into the experimentally poorly accessible sub-THz frequency range. The feasibility of using the coherent synchrotron radiation in scientific applications was demonstrated in a series of experiments: We investigated shallow single acceptor transitions in stressed and unstressed Ge:Ga by means of photoconductance measurements below 1 THz. We have directly measured the Josephson plasma resonance in optimally doped Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} for the first time and finally we succeeded to confine the sub-THz radiation for spectral near-field imaging on biological samples such as leaves and human teeth.

Local indium segregation and band structure in high efficiencygreen light emitting InGaN/GaN diodes
GaN/InGaN light emitting diodes (LEDs) are commercialized for lighting applications because of the cost efficient way that they produce light of high brightness. Nevertheless, there is significant room for improving their external emission efficiency from typical values below 10 percent to more than 50 percent, which are obtainable by use of other materials systems that, however, do not cover the visible spectrum. In particular, green-light emitting diodes fall short in this respect, which is troublesome since the human eye is most sensitive in this spectral range. In this letter advanced electron microscopy is used to characterize indium segregation in InGaN quantum wells of high-brightness, green LEDs (with external quantum efficiency as high as 15 percent at 75 A/cm2). Our investigations reveal the presence of 1-3 nm wide indium rich clusters in these devices with indium concentrations as large as 0.30-0.40 that narrow the band gap locally to energies as small as 2.65 eV.

Market failures, consumer preferences, and transaction costs inenergy efficiency purchase decisions
Several factors limit the energy savings potential and increase the costs of energy-efficient technologies to consumers. These factors may usefully be placed into two categories; one category is what economists would define as market failures and the other is related to consumer preferences. This paper provides a conceptual framework for understanding the roles of these factors, and develops a methodology to quantify their effects on costs and potentials of two energy efficient end uses - residential lighting and clothes washers. It notes the significant roles played by the high implicit cost of obtaining information about the benefits of the two technologies and the apparent inability to process and utilize information. For compact fluorescent lamps, this report finds a conservative estimate of the cost of conserved energy of 3.1 cents per kWh. For clothes washers, including water savings reduces the cost of conserved energy from 13.6 cents to 4.3 cents per equivalent kWh. Despite these benefits, market share remains low. About 18 million tons of CO2 could be saved cost effectively from 2005 sales of these two technologies alone. The paper also notes that trading of carbon emissions will incur transaction costs that will range from less than 10 cents per …

On the Effect of Local Grain-Boundary Chemistry on the Macroscopic Mechanical Properties of a High Purity Y2O3-Al2O3-Containing Silicon Nitride Ceramic: Role of Oxygen
The effects of grain-boundary chemistry on the mechanical properties were investigated on high-purity silicon nitride ceramics, specifically involving the role of oxygen. Varying the grain-boundary oxygen content, by control of oxidizing heat treatments and sintering additives, was found to result in a transition in fracture mechanism from transgranular to intergranular fracture, with an associated increase in fracture toughness. This phenomenon is correlated to an oxygen-induced change in grain-boundary chemistry that appears to affect fracture by ''weakening'' the interface, facilitating debonding and crack advance along the boundaries, and consequently toughening by grain bridging. It is concluded that if the oxygen content in the thin grain-boundary films exceeds a lower limit, which is {approx}0.87 equiv% oxygen content, then the interfacial structure and bonding characteristics favor intergranular debonding during crack propagation; otherwise, transgranular fracture ensues.

Optical injection probing of single ZnO tetrapod lasers
The properties of zinc oxide (ZnO) nanotetrapod lasers are characterized by a novel ultrafast two-color pump/stimulated emission probe technique. Single legs of tetrapod species are isolated by a microscope objective, pumped by 267 nm pulses, and subjected to a time-delayed 400 nm optical injection pulse, which permits investigation of the ultrafast carrier dynamics in the nanosize materials. With the optical injection pulse included, a large increase in the stimulated emission at 400 nm occurs, which partially depletes the carriers at this wavelength and competes with the normal 390 nm lasing. At the 390 nm lasing wavelengths, the optical injection causes a decrease in the stimulated emission due to the energetic redistribution of the excited carrier depletion, which occurs considerably within the time scale of the subpicosecond duration of the injection pulse. The effects of the optical injection on the spectral gain are employed to probe the lasing dynamics, which shows that the full width at half maximum of the lasing time is 3 ps.

The Protecting Seniors from Fraud Act: Status of the Triad Program
Correspondence issued by the Government Accountability Office with an abstract that begins "The Protecting Seniors from Fraud Act of 2000 directed the Comptroller General to submit a report to Congress on the effectiveness of the Triad program by April 4, 2005. The program, sponsored at the national level by the National Sheriffs' Association (NSA), provides advice, training, and technical assistance to communitybased crime prevention programs for senior citizens but does not fund them. These community-based groups typically are partnerships among local law enforcement officials, seniors, and sometimes other community members to develop and expand crime prevention programs for seniors in their communities. NSA has sponsored the Triad program with funds provided by various Department of Justice (DOJ) grants. The act's provisions included support for the Triad senior fraud prevention program, the dissemination of information to states to raise awareness about the dangers of telemarketing and sweepstakes fraud, and mandates to study crimes against seniors and to collect statistics on crimes disproportionately affecting seniors. With regard to our report, the act specified that it include an analysis of the Triad program and activities, identify impediments to establishing community-based Triad groups across the nation, and make recommendations to improve the effectiveness of …

Secular Trends and Climate Drift in Coupled Ocean-Atmosphere General Circulation Models
Coupled ocean-atmosphere general circulation models (coupled GCMs) with interactive sea ice are the primary tool for investigating possible future global warming and numerous other issues in climate science. A long-standing problem with such models is that when different components of the physical climate system are linked together, the simulated climate can drift away from observations unless constrained by ad hoc adjustments to interface fluxes. However, eleven modern coupled GCMs--including three that do not employ flux adjustments--behave much better in this respect than the older generation of models. Surface temperature trends in control run simulations (with external climate forcing such as solar brightness and atmospheric carbon dioxide held constant) are small compared with observed trends, which include 20th century climate change due to both anthropogenic and natural factors. Sea ice changes in the models are dominated by interannual variations. Deep ocean temperature and salinity trends are small enough for model control runs to extend over 1000 simulated years or more, but trends in some regions, most notably the Arctic, are inconsistent among the models and may be problematic.

Solid State, Surface and Catalytic Studies of Oxides
This project investigates the catalytic properties of oxides for the selective oxidative dehydrogenation of light alkanes and for hydrocarbon reduction of NO{sub x}. Various vanadium oxide based catalysts were investigated to elucidate the relationship between the chemical and structural properties of the catalysts and their selectivity for the formation of alkenes. It was found that vanadium oxide units that are less reducible give higher selectivities. For hydrocarbon reduction of NO{sub x}, it was found that alumina-based catalysts can be effective at higher temperatures than the corresponding zeolite-based catalysts. On some catalysts, such as SnO{sub 2}/Al{sub 2}O{sub 3}. Ag/Al{sub 2}O{sub 3}, the alumina participates directly in the reaction, making the catalyst bifunctional. These results are useful in research to improve the performance of this stress of catalysts.
