Primordial metallic melt in the deep mantle

Seismic tomography models reveal two large low shear velocity provinces (LLSVPs) that identify large-scale variations in temperature and composition in the deep mantle. Other characteristics include elevated density, elevated bulk sound speed, and sharp bo ...

Exploring the aqueous vertical ionization of organic molecules by molecular simulation and liquid microjet photoelectron spectroscopy

Jeremy Samuel Arey, Peter Rudolf Tentscher, Jennifer Guerard

To study the influence of aqueous solvent on the electronic energy levels of dissolved organic molecules, we conducted liquid microjet photoelectron spectroscopy (PES) measurements of the aqueous vertical ionization energies (VIEaq) of aniline (7.49 eV), v ...

The boron-tailing myth in hydrogenated amorphous silicon solar cells

Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Grégory Bugnon, Michael Elias Stückelberger

The boron-tailing effect in hydrogenated amorphous silicon (a-Si:H) solar cells describes the reduced charge collection specifically in the blue part of the spectrum for absorber layers deposited above a critical temperature. This effect limits the device ...

Emergence of One-Dimensional Wires of Free Carriers in Transition-Metal-Dichalcogenide Nanostructures

Nicola Marzari, Marco Gibertini

We highlight the emergence of metallic states in two-dimensional transition-metal-dichalcogenide nanostructures nanoribbons, islands, and inversion domain boundaries as a widespread and universal phenomenon driven by the polar discontinuities occurring at ...

Mapping environmental partitioning properties of nonpolar complex mixtures by use of GCxGC

Jeremy Samuel Arey, Jonas Gros, Petros Dimitriou Christidis, Deedar Nabi

Comprehensive two-dimensional gas chromatography (GC × GC) is effective for separating and quantifying nonpolar organic chemicals in complex mixtures. Here we present a model to estimate 11 environmental partitioning properties for nonpolar analytes based ...

Massively parallel molecular dynamics simulation of formation of clathrate-hydrate precursors at planar water-methane interfaces: Insights into heterogeneous nucleation

Simone Meloni

The formation of methane-hydrate precursors at large planar water-methane interfaces has been studied using massively parallel molecular dynamics in systems of varying size from around 10 000 to almost 7 x 10(6) molecules. This process took two distinct st ...

Equation of state of lead from high-pressure neutron diffraction up to 8.9 GPa and its implication for the NaCl pressure scale

Jonathan White

From high-resolution neutron-diffraction experiments we present equation-of-state (EOS) data of elemental lead as functions of both temperature (80-298 K) and applied pressure (up to 8.9 GPa), with the pressure values derived from the NaCl pressure gauge. ...

Formation energies and charge transition levels of amphoteric defects in GaAs giving rise to Fermi-level pinning are calculated with hybrid functionals. The hybrid functional results indicate that previously identified defects involving the bistable nature ...
