Materials development and field demonstration of high-recycled-content concrete for energy-efficient building construction

Description: The project developed high-recycled-content concrete material with balanced structural and thermal attributes for use in energy-efficient building construction. Recycled plastics, tire, wool, steel and concrete were used as replacement for coarse aggregates in concrete and masonry production. With recycled materials the specific heat and thermal conductivity of concrete could be tailored to enhance the energy-efficiency of concrete buildings. A comprehensive field project was implemented which … more

Direct Push Groundwater Circulation Wells for Remediation of BTEX and Volatile Organics

Description: Direct push groundwater circulation wells (DP-GCW) are a promising technology for remediation of groundwater contaminated with dissolved hydrocarbons and chlorinated solvents. In these wells, groundwater is withdrawn from the formation at the bottom of the well, aerated and vapor stripped and injected back into the formation at or above the water table. Previous field studies have shown that: (a) GCWs can circulate significant volumes of groundwater; and (b) GCWs can effectively remove volatile… more

Optimization of the Cathode Long-Term Stability in Molten Carbonate Fuel Cells: Experimental Study and Mathematical Modeling

Description: The dissolution of NiO cathodes during cell operation is a limiting factor to the successful commercialization of molten carbonate fuel cells (MCFCs). Microencapsulation of the NiO cathode has been adopted as a surface modification technique to increase the stability of NiO cathodes in the carbonate melt. The material used for surface modification should possess thermodynamic stability in the molten carbonate and also should be electro catalytically active for MCFC reactions. A simple first pri… more

Identification and temporal behavior of radical intermediates formed during the combustion and pyrolysis of gaseous fuels: Kinetic pathways to soot formation. Final performance report, July 1, 1997 - September 30, 2000

Description: A shock tube coupled to a time-of-flight mass spectrometer has been employed to analyze the dynamic behavior of reactants, products, and intermediates in those reaction systems which are most pertinent to understanding the chemistry attendant to the soot formation process. The measurement of the decay rates of the reactants, the rate of formation of intermediates and products have been used to determine rate constants over a wide temperature range. Recent examples include the pyrolyses of allen… more

Coal/Polymer Coprocessing With Efficient Use of Hydrogen

Description: The final project period was devoted to investigating the binary mixture pyrolysis of polypropylene and polystyrene. Their interactions were assessed in order to provide a baseline for experiments with multicomponent mixtures of polymers with coal. Pyrolysis of polypropylene, polystyrene and their binary mixture was investigated at temperatures of 350 C and 420 C with reaction times from 1 to 180 minutes. Two different loadings, 10 mg and 20 mg, were studied for neat polypropylene and polystyre… more

Petawatt Laser Data Analysis and Technology Development

Description: The Petawatt (PW) laser beam line at the LLNL Nova laser facility was unique in the world in supplying an order of magnitude higher power (1PW in pulses of 500 fs duration) than lasers elsewhere. Focused to intensities reaching 3 x l0{sup 20} Wcm{sup -2}, it opened up a new regime of experimental science where free electron energies in the light wave are strongly relativistic. After full operational capability of the PW beam-line was reached, close to 25% of the operation of the Nova facility w… more

Hydrologic Behavior of Two Engineered Barriers Following Extreme Wetting

Description: Many engineered barriers are expected to function for hundreds of years or longer. Over the course of time, it is likely that some barriers will experience infiltration to the point of breakthrough. This study compares the recovery from breakthrough of two storage- evapotranspiration type engineered barriers. Replicates of test plots comprising thick soil and capillary/biobarrier covers were wetted to breakthrough in 1997. Test plots were kept cleared of vegetation to maximize hydrologic stress… more

Microbial Transformations of Plutonium and Implications for Its Mobility.

Description: The current state of knowledge of the effect of plutonium on microorganisms and microbial activity is reviewed, and also the microbial processes affecting its mobilization and immobilization. The dissolution of plutonium is predominantly due to their production of extracellular metabolic products, organic acids, such as citric acid, and sequestering agents, such as siderophores. Plutonium may be immobilized by the indirect actions of microorganisms resulting in changes in Eh and its reduction f… more

Novel Mass Spectrometry Mutation Screening for Contaminant Impact Analysis

Description: Due to the limited budget of waste clean-up for all DOE contamination sites, it is critical to have a sound risk analysis with strong scientific basis to set priority for waste clean-up. In the past, the priority was often determined mostly by the type and quantity of pollutants and the observation of cancer rate increase. Since human cancers can be caused by various reasons in addition to environmental contamination, a rigorous study to find the relationship between specific contaminants and c… more

Rational Design of Metal Ion Sequestering Agents

Description: The discriminate bonding of metal ions is a challenge to the synthetic chemist and a phenomenon of considerable practical importance.1 An important feature of many technical applications is the specific or preferential binding of a single metal ion in the presence of many metals. Examples range from large-volume uses (e.g. ferric EDTA as a plant food, calcium complexing agents as water softeners or anticaking formulations) to very high technology applications (technetium complexation in radioph… more

System Design of a Natural Gas PEM Fuel Cell Power Plant for Buildings

Description: The following conclusions are made based on this analysis effort: (1) High-temperature PEM data are not available; (2) Stack development effort for Phase II is required; (3) System results are by definition preliminary, mostly due to the immaturity of the high-temperature stack; other components of the system are relatively well defined; (4) The Grotthuss conduction mechanism yields the preferred system characteristics; the Grotthuss conduction mechanism is also much less technically mature tha… more

Frequency Modulation Spectroscopy Modeling for Remote Chemical Detection

Description: Frequency modulation (FM) spectroscopy techniques show promise for active infrared remote chemical sensing. FM spectroscopy techniques have reduced sensitivity to optical and electronic noise, and are relatively immune to the effects of various electronic and mechanical drifts. FM systems are responsive to sharp spectral features and can therefore reduce the effects of spectral clutter due to interfering chemicals in the plume or in the atmosphere. The relatively high modulation frequencies use… more
