Characterization of Palladium and Ruthenium after Reaction with Tetraphenylborate and Mercury (open access)

Characterization of Palladium and Ruthenium after Reaction with Tetraphenylborate and Mercury

This report documents a second series of X-ray fine structure and chemical analyses to examine the form that Pd - and, to a lesser extent, ruthenium (Ru) - takes in simulated high-level slurries containing TPB salts.

Development of a high density pixel multichip module at Fermilab (open access)

Development of a high density pixel multichip module at Fermilab

At Fermilab, a pixel detector multichip module is being developed for the BTeV experiment. The module is composed of three layers. The lowest layer is formed by the readout integrated circuits (ICs). The back of the ICs is in thermal contact with the supporting structure, while the top is flip-chip bump-bonded to the pixel sensor. A low mass flex-circuit interconnect is glued on the top of this assembly, and the readout IC pads are wire-bounded to the circuit. This paper presents recent results on the development of a multichip module prototype and summarizes its performance characteristics.

Effect of catalyst structure on oxidative dehydrogenation of ethane and propane on alumina-supported vanadia (open access)

Effect of catalyst structure on oxidative dehydrogenation of ethane and propane on alumina-supported vanadia

The catalytic properties of Al2O3-supported vanadia with a wide range of VOx surface density (1.4-34.2 V/nm2) and structure were examined for the oxidative dehydrogenation of ethane and propane. UV-visible and Raman spectra showed that vanadia is dispersed predominantly as isolated monovanadate species below {approx}2.3 V/nm2. As surface densities increase, two-dimensional polyvanadates appear (2.3-7.0 V/nm2) along with increasing amounts of V2O5 crystallites at surface densities above 7.0 V/nm2. The rate constant for oxidative dehydrogenation (k1) and its ratio with alkane and alkene combustion (k2/k1 and k3/k1, respectively) were compared for both alkane reactants as a function of vanadia surface density. Propene formation rates (per V-atom) are {approx}8 times higher than ethene formation rates at a given reaction temperature, but the apparent ODH activation energies (E1) are similar for the two reactants and relatively insensitive to vanadia surface density. Ethene and propene formation rates (per V-atom) are strongly influenced by vanadia surface density and reach a maximum value at intermediate surface densities ({approx}8 V/nm2). The ratio of k2/k1 depends weakly on reaction temperature, indicating that activation energies for alkane combustion and ODH reactions are similar. The ratio of k2/k1 is independent of surface density for ethane, but increase slightly with vanadia surface …

Effect of ethanol fuel additive on diesel emissions. (open access)

Effect of ethanol fuel additive on diesel emissions.

Engine-out emissions from a Volkswagen model TDI engine were measured for three different fuels: neat diesel fuel, a blend of diesel fuel and additives containing 10% ethanol, and a blend of diesel fuel and additives containing 15% ethanol. The test matrix covered five speeds from 1,320 to 3,000 rpm, five torques from 15 Nm to maximum plus the 900-rpm idle condition, and most of the points in the FTP-75 and US-06 vehicle tests. Emissions of particulate matter (PM), nitrogen oxides (NO{sub x}), unburned hydrocarbons (HCs), and carbon monoxide (CO) were measured at each point, as were fuel consumption, exhaust oxygen, and carbon dioxide output. PM emissions were reduced up to 75% when ethanol-diesel blends were used instead of neat diesel fuel. Significant reductions in PM emissions occurred over one-half to two-thirds of the test matrix. NO{sub x} emissions were reduced by up to 84%. Although the regions of reduced NO{sub x} emissions were much smaller than the regions of reduced PM emissions, there was considerable overlap between the two regions where PM emissions were reduced by up to 75% and NO{sub x} emissions were reduced by up to 84%. Such simultaneous reduction of both PM and NO{sub x} emissions would …

Evaluating DNAPL Source and Migration Zones: M-Area Settling Basin and the Western Sector of A/M Area, Savannah River Site (open access)

Evaluating DNAPL Source and Migration Zones: M-Area Settling Basin and the Western Sector of A/M Area, Savannah River Site

The objective of this investigation is to critically evaluate previous characterization and remediation data to determine the current extent and distribution of DNAPL associated with releases at the M-Area Basin within A/M Area. The primary objective of the effort is to develop an approximate recommendation for the target treatment location and volume near the M Area Settling Basin. Through this analysis the final objective is to identify those subsurface regions having specific geometry and character necessary to cost-effectively deploy DNAPL specific remediation alternatives.

Influence of Water Addition on Crystalline Silicotitanate Column Operation (open access)

Influence of Water Addition on Crystalline Silicotitanate Column Operation

The proposed use of crystalline silicotitanate (CST) for removal of radiocesium from Savannah River high level waste has received significant research over the past few years. Engineering evaluations of the proposed flow sheet identified several risks. These risks include chemical and thermal stability of the resin, gas generation in the large ion exchange columns, and size reduction and sampling issues for interfacing with the Defense Waste Processing Facility. Research into these potential risks provided information that mitigates or eliminates these risks.
