A membrane-less electrolyzer with porous walls for high throughput and pure hydrogen production dagger

Demetri Psaltis, Seyyed Mohammad Hosseini Hashemi, Pooria Hadikhani, Steven Alexandre Schenk

Membrane-less electrolyzers utilize fluidic forces instead of solid barriers for the separation of electrolysis gas products. These electrolyzers have low ionic resistance, a simple design, and the ability to work with electrolytes at different pH values. ...

Influence of thermo-mechanical processing on ordering kinetics in 18 karat red gold alloy

Marina Garcia Gonzalez

The aim of this project is to understand the correlation between alloy composition and the build-up of internal stresses in 18 carat Au-Ag-Cu alloys under thermo-mechanical loads. The copper rich end of this ternary system exhibits order-hardening of the e ...

Solute/screw dislocation interaction energy parameter for strengthening in bcc dilute to high entropy alloys

William Curtin, Francesco Maresca, Alireza Ghafarollahi

Strengthening, i.e. increased stress required to move a dislocation, in dilute or complex alloys arises from the totality of the interaction energies between the solutes and an individual dislocation. Prevailing theories for strengthening in bcc alloys con ...

Metal artefact reduction in computed tomography images by a fourth-order total variation flow

Alfio Quarteroni, Elena Faggiano

Permanent metallic implants, such as dental fillings and cardiac devices, generate streaks-like artefacts in computed tomography (CT) images. In this article, we propose a strategy to perform metal artefact reduction (MAR) that relies on the total variatio ...

In situ X-ray Diffraction during Casting: Study of Hot Tearing in Al-Zn alloys

Jean-Marie Drezet, Güven Kurtuldu, Bastien Gilbert Pierre Mireux

During solidification of metallic alloys, coalescence corresponds to the formation of solid bridges between grains when both solid and liquid phases are percolated. As such, it represents a key transition with respect to the mechanical behaviour of solidif ...

Infiltration of tin bronze into alumina particle beds: influence of alloy chemistry on drainage curves

Andreas Mortensen, Ludger Weber, Alain Léger

The wetting of angular alumina particle preforms by Cu-Sn alloys is investigated by means of pressure infiltration experiments conducted at 1150 A degrees C, using a system enabling dynamic and precise measurements of the metal volume injected into the pre ...

Influence of microstructural heterogeneity on the scaling between flow stress and relative density in microcellular Al-4.5 %Cu

Andreas Mortensen, Yves Conde

We explore the influence of the metal microstructure on the compressive flow stress of replicated microcellular 400-mu m pore size Al-4.5 wt%Cu solidified at two different solidification cooling rates, in the as-cast and T6 conditions. It is found that the ...

Wear and frictional mechanisms of copper-based bearing alloys

Stefano Mischler

The present study investigated the role of alloy microstructure and surface roughness on wear and friction behavior of leaded and unleaded tin bronzes. Ball-on-disk experiments were carried out under dry conditions with steel balls sliding against bronze d ...

Spectroscopic Studies on Iron-Chalcogenide Superconductors

Ping-Hui Lin

Superconductivity in F-doped LaFeAsO, Tc= 26 K was first reported by Kamihara et al in 2008. Following that, more iron-based superconductors, e.g., (Ba,K)Fe2As2, LiFeAs, and Fe1+yTe1-xSex were discovered. The new class of high Tc superconductors have attra ...

Compensation mechanism in silicon-doped gallium arsenide nanowires

Anna Fontcuberta i Morral, Emanuele Uccelli, Bernt Ketterer

P-type gallium arsenide nanowires were grown with different silicon doping concentrations. The incorporation is monitored by Raman spectroscopy of the local vibrational modes. For Si-concentrations up to 1.4 x 10(18) cm(-3), silicon incorporates mainly in ...
