Accelerated Processing of SB4 and Preparation for SB5 Processing at DWPF
The Defense Waste Processing Facility (DWPF) initiated processing of Sludge Batch 4 (SB4) in May 2007.SB4 was the first DWPF sludge batch to contain significant quantities of HM or high Al sludge.Initial testing with SB4 simulants showed potential negative impacts to DWPF processing; therefore, Savannah River National…
Kinetics of the initial stage of silicon surface oxidation: Deal–Grove or surface nucleation?
The nucleation-initiated oxidation of a Si surface at very low temperatures in plasmas is demonstrated experimentally, in contrast to the Deal–Grove mechanism, which predicts Si oxidation at a Si/SiO interface and cannot adequately describe the formation of SiO nanodots and oxidation rates at very low (several nanomet…

Liquid Front Profiles Affected by Entanglement-induced Slippage
Hydrodynamic slippage plays a crucial role in the flow dynamics of thin polymer films, as recently shown by the analysis of the profiles of liquid fronts. For long-chained polymer films it was reported that a deviation from a symmetric profile is a result of viscoelastic effects. In this Letter, however, evidence is g…

Non-Korringa nuclear relaxation in the ferromagnetic phase of the bilayered manganite La1.2Sr1.8Mn2O7
In contrast to ferromagnetic (FM) three-dimensional manganites, $^{55}\text{M}\text{n}$ NMR spectra obtained for the FM phase of the colossal magnetoresistance bilayer manganite ${\text{La}}_{1.2}{\text{Sr}}_{1.8}{\text{Mn}}_{2}{\text{O}}_{7}$ show a broad distribution of hyperfine fields at Mn sites. The hyperfine di…
Surface decorated silicon nanowires: a route to high-ZT thermoelectrics
Based on atomistic calculations of electron and phonon transport, we propose to use surface decorated Silicon nanowires (SiNWs) for thermoelectric applications. Two examples of surface decorations are studied to illustrate the underlying deas: Nanotrees and alkyl functionalized SiNWs. For both systems we find, (i) tha…
Orientation-switching transition and ferroelectricity in betaine arsenate
This paper reports a detailed investigation of the low frequency dielectric relaxation of betaine arsenate near the ferroelectric phase transition. The dielectric relaxation data are complemented with polarized infrared reflectivity data taken at low temperatures. The reported results allow us to identify several low…
A modified time-dependent perturbation approach to quantum dynamics and its application to relaxation phenomena in magnetic molecules
We introduce a modified version of the interaction picture applicable to situations in which the nonperturbed Hamiltonian is time-dependent but can be diagonalized by the same basis of states at all times. We probe the method using a simple model Hamiltonian to study the spin dynamics of molecular magnets with time-de…

Influence of Surface Active Solute on Ultrasonic Waveform Distortion in Liquid Containing Air Bubbles
The influence of sodium dodecyl sulfate (SDS) on waveform distortion of 141 kHz ultrasonic standing waves in liquids containing air bubbles was investigated for various transducer powers. Fast Fourier transform (FFT) operations were performed on the pressure waveform to obtain the harmonic components. In addition, the…
