Effects of bonding type and interface geometry on coherent transport through the single-molecule magnet Mn-12
(American Physical Society, 2010-03)
We examine theoretically coherent electron transport through the single-molecule magnet Mn-12, bridged between Au(111) electrodes, using the nonequilibrium Green's function method and the density-functional theory. We ...
Elements, Fall 2010
(Virginia Tech, 2010)
This is the alumni magazine of the Department of Chemistry at Virginia Tech.
Biospheric Changes are Threat Multipliers
(National Academy of Sciences, 2010)
A threat multiplier is defined as another agent that impacts a current situation, creating an additional set of problems while also making existing problems worse. Sometimes a seemingly innocent change in the biosphere ...
Communicating the Processes of Science to the News Media, Politcians, and the Public
(Society of Environmental Toxicology and Chemistry, 2010)
The discourse between scientists and politicians and news media must be improved in order to communicate complex environmental issues such as climate change, biodiversity loss, ecological overshoot, or exponential population ...
Deformation of a hydrophobic ferrofluid droplet suspended in a viscous medium under uniform magnetic fields
(Cambridge University Press, 2010-11)
The effect of applied magnetic fields on the deformation of a biocompatible hydrophobic ferrofluid drop suspended in a viscous medium is investigated numerically and compared with experimental data. A numerical formulation ...
radial velocity offsets due to mass outflows and extinction in active galactic nuclei
(IOP Publishing Ltd., 2010-01)
We present a study of the radial velocity offsets between narrow emission lines and host galaxy lines (stellar absorption and Hi 21 cm emission) in Seyfert galaxies with observed redshifts less than 0.043. We find that 35% ...
physical conditions in the ultraviolet absorbers of IRAS F22456-5125
(IOP Publishing Ltd., 2010-04)
We present the ultraviolet (UV) and X-ray spectra observed with the Far Ultraviolet Spectroscopic Explorer (FUSE) and the XMM-Newton satellite, respectively, of the low-z Seyfert 1 galaxy IRAS F22456-5125. This object shows ...
Ionization-driven Fragmentation of Gas Outflows Responsible for FeLoBALs in Quasars
(IOP PUBLISHING LTD, 2010-07)
We show that time variations in the UV ionizing continuum of quasars, on scales of similar to 1 yr, affect the dynamic structure of the plasmas responsible for low-ionization broad absorption lines. Variations of the ...
Ion transport and storage of ionic liquids in ionic polymer conductor network composites
(AIP Publishing, 2010-05-01)
We investigate ion transport and storage of ionic liquids in ionic polymer conductor network composite electroactive devices. Specifically, we show that by combining the time domain electric and electromechanical responses, ...
