Hydrogenation Of Magnesium Nanoblades: The Effect Of Concentration Dependent Hydrogen Diffusion,

Hydrogenation Of Magnesium Nanoblades: The Effect Of Concentration Dependent Hydrogen Diffusion, Bo Yang, Yuping He, Yiping Zhao
Aerospace, Physics, and Space Science Faculty Publications
By assuming the H diffusion coefficient and H adsorption rate to be exponentially and linearly dependent on concentration, a physical model is developed to predict the hydrogenation process of Mg nanoblades. The predicted H uptake curves agree well with the experimental data from V-coated Mg nanoblades. The obtained H diffusion coefficients in MgHx between Mg and MgH2 have nearly three orders of magnitude variation. The characteristic time of H surface adsorption is longer than that of H diffusion in Mg but shorter than that in MgH2 for 100 nm thick nanoblades. A hydride shell is not formed during the hydrogenation.

Flux Variation Of Cosmic Muons, N. Ramesh, M. Hawron, C. Martin, A. Bachri
Journal of the Arkansas Academy of Science
In the current paper, we analyzed the variation of cosmic radiation flux with elevation, time of the year and ambient temperature with the help of a portable cosmic muon detector, the construction of which was completed by a team from Southern Arkansas University (SAU) at Lawrence Berkeley National Laboratory (LBNL). Cosmic muons and gamma rays traverse two synchronized scintillators connected to two photomultiplier tubes (PMT) via light guides, and generate electronic pulses which we counted using a Data Acquisition Board (DAQ). Because muons are the product of collisions between high-energy cosmic rays and atmospheric nuclei, and therefore shower onto earth, …

Fourier Transform Emission Spectroscopy Of Yh And Yd: Observation Of New A¹Δ And B¹Π Electronic States, R. S. Ram, G. Li, P. F. Bernath
Chemistry & Biochemistry Faculty Publications
The emission spectra of YH and YD molecules have been investigated in the 3600–12 000 cm−1 region using a Fourier transform spectrometer. Molecules were formed in an yttrium hollow cathode lamp operated with a continuous flow of a mixture of Ne and Ar gases, and YH and YD were observed together in the same spectra. A group of bands observed near 1 μm have been identified as 0-0 and 1-1 bands of the A1Δ-X1Σ+ and B1Π-X1Σ+ transitions of YH and the 0-0 bands of the same two transitions …

Combustion Of Lunar Regolith Mixed With Energetic Additives: Thermodynamic Calculations And Experimental Studies, Francisco Alvarez
Open Access Theses & Dissertations
The future of space exploration will require longer missions in order to better understand the conditions of near-Earth celestial objects, like the Moon or Mars. Future space missions will require the development of goods, such as propulsion fuel and structural materials, produced using the extraterrestrial resources available. The area that develops these technologies is called In-Situ Resource Utilization (ISRU). ISRU allows reducing the payload, and as a consequence reduces the energy consumption and cost of space travel. The production of structural materials on the Moon can be accomplished using Self-Propagating High-Temperature Synthesis (SHS). This work describes the combination of ISRU …

The Core Collapse Supernova Rate In The Sdss-Ii Supernova Survey, Matthew Frederick Taylor
Wayne State University Dissertations
The Sloan Digital Sky Survey II Supernova Survey (SDSS-II SN), though designed as a type Ia supernova search for cosmology, also discovered a large sample of core collapse supernovae (CCSN). I use the SDSS-II SN data to measure the volumetric CCSN rate in the redshift range (0.03 < z < 0.09), finding a volume-averaged rate of 0.98±0.18 ×10⊃−4⊃h⊂70⊂⊃3⊃yr⊃−1⊃Mpc⊃−3⊃. The CCSN luminosity function is also extracted from the data, and its implications on the cosmic star formation history are considered.
Magnetic-Field Induced Stability In Two-Flavor Color Superconductivity,

Magnetic-Field Induced Stability In Two-Flavor Color Superconductivity, Churna B. Bhandari
Open Access Theses & Dissertations
It has long been understood that the ground state of a superdense quark system, a Fermi liquid of weakly interacting quarks, is unstable with respect to the formation of diquark condensates. This nonperturbative phenomenon is essentially equivalent to the Cooper instability of conventional BCS superconductivity. As the quark pairs have nonzero color charge, this kind of superconductivity breaks the SU(3) color gauge symmetry, thus it is called color superconductivity. A peculiar feature of spin-zero color superconductivity is the lack of Meissner effect for a combination of the regular electromagnetic field and one of the gluon fields. This combination behaves as …

Context. After the launch of the Swift satellite, the gamma-ray burst (GRB) optical light-curve smoothness paradigm has been questioned thanks to the faster and better sampled optical follow-up, which has unveiled a very complex behaviour. This complexity is triggering the interest of the whole GRB community. The GROND multi-channel imager is used to study optical and near-infrared (NIR) afterglows of GRBs with unprecedented optical and near-infrared temporal and spectral resolution. The GRB 081029 has a very prominent optical rebrightening event and is an outstanding example of the application of the multi-channel imager to GRB afterglows. Aims. Here we exploit the …

Variable High-Order Overset Grid Methods For Mixed Steady And Unsteady Multiscale Viscous Hypersonic Nonequilibrium Flows, A. Lani, Bjorn Sjögreen, Helen Yee, W, D. Henshaw
United States National Aeronautics and Space Administration: Publications
The objective of the current paper † is a further validation of the overset grid capability for high-speed chemical nonequilibrium flows. The current investigation, which is a follow-up on previous work by (Sj¨ogreen & Yee 2009b), (Lani et al. 2010a), (Wang et al. 2009), (Wang et al. 2010), (Lani et al. 2010b), extends the use of variable order methods for both inviscid and viscous chemical nonequilibrium flows with strong shocks on 2D and 3D multiblock overlapping grids. A 5-species and one-temperature air model in chemical nonequilibrium is considered in all cases. Second-order TVD, fifth- or higher-order WENO schemes are applied …

The magnetization dynamics of Co(5 nm)/Ru/Co(5 nm) trilayers with Ru thicknesses from 0.3–0.6 nm is experimentally and theoretically investigated. The coupling between the Co layers is antiferromagnetic (AFM) and yields a stable AFM domain structure with frozen domain walls. Comparing high-resolution magnetic force microscopy (MFM) and pump-probe measurements, we analyze the behavior of the films for different field-strength regimes. For moderate magnetic fields, pump-probe measurements provide dynamic characterization of the coupled precessional modes in the GHz range. The dynamics at small fields is realized by the pinning of AFM domain walls at inhomogeneities. The MFM images yield a domain-wall width …
