First-principles model for phase stability, radiation defects and elastic properties Of W–Ta and W–V alloys

Tungsten alloys are candidate materials for DEMO divertor applications because of their high melting point and low sputtering yield. We explore, using ab initio methods, the phase stability trend of W-Ta and W-V alloys. The available experimental phase dia ...

Phase diagram with an enhanced spin-glass region of the mixed Ising–XY magnet LiHoxEr1-xF4

Henrik Moodysson Rønnow, Ivica Zivkovic, Bastien Dalla Piazza, Julian Piatek, Neda Nikseresht Ghanepour, Nikolay Tsyrulin

We present the experimental phase diagram of LiHoxEr1-xF4, a dilution series of dipolar-coupled model magnets. The phase diagram was determined using a combination of ac susceptibility and neutron scattering. Three unique phases in addition to the Ising fe ...

Field-Induced Quantum Soliton Lattice in a Frustrated Two-Leg Spin-1/2 Ladder

Henrik Moodysson Rønnow, Christian Rüegg, Siyuan Wang, Joël Mesot, Kazimierz Conder

Based on high-field 31P nuclear magnetic resonance experiments and accompanying numerical calculations, it is argued that in the frustrated S=1/2 ladder compound BiCu2PO6 a field-induced soliton lattice develops above a critical field of μ0Hc1=20.96(7) T. ...

Two-phase heat transfer and high-speed visualization of refrigerant flows in 100 × 100 μm2 silicon multi-microchannels

John Richard Thome, Navid Borhani, Sylwia Szczukiewicz

Two-phase flow boiling of R245fa, R236fa, and R1234ze(E) in 100 × 100 μm2 parallel microchannels for cooling of future 3D-ICs has been investigated. Significant flow instabilities, back flow, and non-uniform flow distribution among the channels were observ ...

Seasonal simulation of drifting snow sublimation in Alpine terrain

Michael Lehning

We estimate seasonal drifting snow sublimation at a study site in the Swiss Alps with the numerical model Alpine3D using external wind fields from the Advanced Regional Prediction System on a high-resolution grid (10 m). Novel in the field of snow transpor ...

A printed transition for matching improvement of SIW horn antennas

Juan Ramon Mosig, Jean-François Zürcher, Marc Esquius Morote, Benjamin Fuchs

The substrate integrated waveguide (SIW) technology allows to construct several types of commonly used antennas in a planar way. However, frequency limitations associated to commercial substrates appear in the implementation of certain types of antennas, e ...

Two-Phase Flow Boiling in a Single Layer of Future High-Performance 3D Stacked Computer Chips

John Richard Thome, Navid Borhani, Sylwia Szczukiewicz

The present study focuses on an experimental investigation of two-phase flow boiling in a silicon multi-microchannel evaporator, which emulates a single layer of a 3D stacked computer chip. The micro-evaporator is comprised of 67 parallel channels, each ha ...

Structure and properties of Fe-modified Na_{0.5}Bi_{0.5}TiO_{3} at ambient and elevated temperature

Dragan Damjanovic

Sodium bismuth titanate (NBT) ceramics are among the most promising lead-free materials for piezoelectric applications. This work reports the crystal structure and phase evolution of NBT and Fe-modified NBT (from 0-2 at.% Fe) using synchrotron x-ray diffra ...

Experimental study of single triple-phase-boundary and platinum-yttria stabilized zirconia composite as cathodes for micro-solid oxide fuel cells

Paul Muralt, Silviu Cosmin Sandu, Yan Yan, Janine Conde

Micro-solid oxide fuel cell (mu SOFC) structures with annular Pt electrodes have been fabricated by means of silicon micromachining. The annular cathodes contained a defined triple phase boundary (TPB) length, which allowed the derivation of the ionic curr ...
