Development and characterization of electrochromic oxide and ion conductor deposited by reactive magnetron sputtering

Andreas Schueler, Olivia Valérie Charlotte Bouvard, Djamel Eddine Mansour

In order to modulate the solar gains of a building, electrochromic windows can be used. To improve their durability, inorganic solid state electrolytes are considered. This work reports on the investigation of tungsten trioxide (WO3) and lithium phosphorou ...

Heavy Impurity Confinement in Hybrid Operation Scenario Plasmas with a Rotating 1/1 Continuous Mode

Jonathan Graves, Wilfred Anthony Cooper, David Pfefferlé, Madhusudan Raghunathan

In future tokamaks like ITER with tungsten walls, it is imperative to control tungsten accumulation in the core of operational plasmas, especially since tungsten accumulation can lead to radiative collapse and disruption. We investigate the behaviour of tu ...

In situ core-level and valence-band photoelectron spectroscopy of reactively sputtered tungsten oxide films

Andreas Schueler, Anna Krammer, Olivia Valérie Charlotte Bouvard

In this paper, we study tungsten oxides deposited by reactive magnetron sputtering. The total working pressure during deposition was varied in order to obtain different morphology. The effects on the electronic properties and chemical composition were stud ...

Improving Osteoblast Response In Vitro by a Nanostructured Thin Film with Titanium Carbide and Titanium Oxides Clustered around Graphitic Carbon

Giovanni Longo

Introduction Recently, we introduced a new deposition method, based on Ion Plating Plasma Assisted technology, to coat titanium implants with a thin but hard nanostructured layer composed of titanium carbide and titanium oxides, clustered around graphitic ...

Parasitic Absorption Reduction in Metal Oxide-Based Transparent Electrodes: Application in Perovskite Solar Cells

Christophe Ballif, Sylvain Nicolay, Stefaan De Wolf, Ali Dabirian, Björn Niesen, Monica Morales Masis, Jérémie Werner

Transition metal oxides (TMOs) are commonly used in a wide spectrum of device applications, thanks to their interesting electronic, photochromic, and electrochromic properties. Their environmental sensitivity, exploited for gas and chemical sensors, is how ...

Shape-Dependence of Pd Nanocrystal Carburization during Acetylene Hydrogenation

Lioubov Kiwi, Rocio Micaela Crespo Quesada, Fernando Cardenas Lizana

This interdisciplinary work combines the use of shape- and size-defined Pd nanocrystals (cubes of 10 and 18 nm, and octahedra of 37 nm) with in situ techniques and DFT calculations to unravel the dynamic phenomena with respect to Pd reconstruction taking p ...

Finite element modeling of the WC-10 wt.% Co thermal stresses: Build-up and phase specific strain response during cyclic loading

Daniele Mari, Emiliano Campitelli

Several finite element models of the morphology of WC-10 wt.% Co were employed to reproduce the build-up of thermal residual stresses as well as the phase specific strain during loading-unloading in compression. The different models differ only in their ge ...

Performance of ceramic anvils for high pressure neutron scattering

Livia Eleonora Bove Kado

Three kinds of ceramics, zirconia-toughened alumina (ZTA), alumina-toughened zirconia (ATZ) and yttria-stabilized zirconia (YSZ), were tested as anvil materials, mainly for the purpose of neutron scattering study under high pressure. ZTA with non-toroidal ...

Spin-resolved optical conductivity of two-dimensional group-VIB transition-metal dichalcogenides

Nicola Marzari, Marco Gibertini

We present an ab initio study of the spin-resolved optical conductivity of two-dimensional (2D) group-VIB transition-metal dichalcogenides (TMDs). We carry out fully relativistic density-functional-theory calculations combined with maximally localized Wann ...

Solid Solutions of Lead Metaniobate-Stabilization of the Ferroelectric Polymorph and the Effect on the Lattice Parameters, Dielectric, Ferroelectric, and Piezoelectric Properties

Nava Setter, Dragan Damjanovic, Alberto Biancoli, Barbara Maraston Fraygola, Mtabazi Geofrey Sahini

Ferroelectric orthorhombic lead metaniobate (PbNb2O6) is known to be metastable with respect to the thermodynamically stable nonferroelectric rhombohedral polymorph. The high-temperature tetragonal to low temperature rhombohedral phase transition is recons ...

Thermal boundary conductance between refractory metal carbides and diamond

Christian Monachon, Ludger Weber

The thermal boundary conductance (TBC) between thin films of Cr, Mo, Nb and W and diamond substrates has been measured using time domain thermoreflectance before and after a high-vacuum heat treatment at 800 degrees C for 2 h. While no signs of carbide for ...
