Rapid mobilization of noncrystalline U(IV) coupled with FeS oxidation

Rizlan Bernier-Latmani, Malgorzata Alicja Stylo

The reactivity of disordered, noncrystalline U(IV) species remains poorly characterized despite their prevalence in biostimulated sediments. Because of the lack of crystalline structure, noncrystalline U(IV) may be susceptible to oxidative mobilization und ...

Effect of interfacial interactions on the electromechanical response of poly(vinylidene fluoride-trifluoroethylene)/BaTiO3 composites and its time dependence after poling

Jan-Anders Edvin Maansson, Véronique Michaud, Yves Leterrier, Dragan Damjanovic, Sara Dalle Vacche

Solvent cast and compression molded composite films based on poly(vinylidene fluoride-trifluoroethylene), containing pristine and silylated BaTiO3 particles, were poled, and their electromechanical response (d(33)), their dielectric properties, and the cry ...

Structural peculiarities and aging effect in hydrogenated a-Si prepared by inductively coupled plasma assisted chemical vapor deposition technique

Gizem Nogay

In this study, we report the morphological and structural properties of amorphous and nanocrystalline Si thin films deposited by inductively coupled plasma-assisted chemical vapor deposition (ICP-CVD) technique at low substrate temperatures using H-2 dilut ...

Process influences on the structure, piezoelectric, and gas-barrier properties of PVDF-TrFE copolymer

Jan-Anders Edvin Maansson, Yves Leterrier, Dragan Damjanovic, Antonia Neels, Alex Dommann, Olha Sereda

The influence of annealing between the Curie transition and the melting point of solvent cast polyvinylidene fluoride trifluoroethylene copolymer films on the crystalline structure, mechanical and electrical properties, and oxygen permeability is investiga ...

The product of microbial uranium reduction includes multiple species with U(IV)-phosphate coordination

Rizlan Bernier-Latmani, Daniel Scott Alessi

Until recently, the reduction of U(VI) to U(IV) during bioremediation was assumed to produce solely the sparingly soluble mineral uraninite, UO2(s). However, results from several laboratories reveal other species of U(IV) characterized by the absence of an ...

Simultaneous neutron transmission and diffraction contrast tomography as a non-destructive 3D method for bulk single crystal quality investigations

Steven Luc X Peetermans

Traditional neutron tomography allows to reconstruct the attenuation cross section, a measure for the material distribution, at high spatial resolution and non-destructively. However, it does not state anything about the ordering structure of the atoms ins ...

Energy-selective neutron imaging for morphological and phase analysis of iron-nickel meteorites

Steven Luc X Peetermans

We propose energy-selective neutron imaging as a new and non-destructive method to investigate rare metallic meteorites. It is based on attenuation of a neutron beam of limited spectral distribution in a sample depending on the elemental composition and cr ...

Structural and magnetic properties of epitaxial Co2FeAl films grown on MgO substrates for different growth temperatures

Santiago Serrano Guisan

We report the correlation between the crystalline structure, electronic structure and magnetic properties of Co2FeAl films as a function of growing temperature both experimentally and theoretically. The Co2FeAl film grown at room temperature is initially i ...

Interface Investigations on Titanium Nitride Bilayer Systems

Nanocomposite coatings composed of two phases with atomically sharp phase boundaries, show interesting mechanical properties. These properties are often originating from their high interface to volume ratio. Composites of nanocrystalline titanium nitride ( ...

Comparative evaluation of particle properties, formation of reactive oxygen species and genotoxic potential of tungsten carbide based nanoparticles in vitro

Kristin Schirmer

Tungsten carbide (WC) and cobalt (Co) are constituents of hard metals and are used for the production of extremely hard tools. Previous studies have identified greater cytotoxic potential of WC-based nanopartides if particles contained Co. The aim of this ...

Subangstrom Edge Relaxations Probed by Electron Microscopy in Hexagonal Boron Nitride

Oleg Yazyev

Theoretical research on the two-dimensional crystal structure of hexagonal boron nitride (h-BN) has suggested that the physical properties of h-BN can be tailored for a wealth of applications by controlling the atomic structure of the membrane edges. Unexp ...
