Ab initio Modelling of the Early Stages of Precipitation in Al-6000 Alloys

Michele Ceriotti, William Curtin, Till Junge, Daniele Giofré

Age hardening induced by the formation of (semi)-coherent precipitate phases is crucial for the processing and final properties of the widely used Al-6000 alloys. Early stages of precipitation are particularly important from the fundamental and technologic ...

HTS high current cable for fusion application

Nikolay Bykovskiy

State-of-the-art magnets of fusion devices, which are based on low temperature superconductors (LTS), have almost reached their technological limits in terms of generated magnetic fields. Further progress can be made using novel high temperature supercondu ...

Coupled 3D Dislocation Modeling at Nano- and Micro-Scales

Jaehyun Cho

The performance of crystalline materials varies depending on the considered scale. To understand the size dependence of materials properties, the interaction and evolution of defects are essential. As such, the role played by dislocations is crucial for mo ...

Crack growth and fracture toughness of amorphous Li-Si anodes: Mechanisms and role of charging/discharging studied by atomistic simulations

William Curtin, Seyed Mostafa Khosrownejad

Fracture is the main cause of degradation and capacity fading in lithiated silicon during cycling. Experiments on the fracture of lithiated silicon show conflicting results, and so mechanistic models can help interpret experiments and guide component desig ...

Advanced Plasmonic Nanostructures for Engineering Fluorescence Applications

Xiaolong Wang

The appeal of plasmonics lies in the unique properties of coinage metal nanoparticles to strongly confine and enhance electromagnetic fields at the subwavelength. A simple 50 nm colloidal plasmonic particle can not only break the classical diffraction limi ...

Thermal-Hydraulic Analysis of the Low-T-c Superconductor (LTS) Winding Pack Design Concepts for the DEMO Toroidal Field (TF) Coil

Kamil Sedlák

Three design concepts, namely, WP#1, WP#2, and WP#3, for the low-T-c superconductor DEMO toroidal field coil was proposed in 2014. This paper is focused on the thermal-hydraulic analysis of all the designs using simplified models, which includes: 1) hydrau ...

Structure of amorphous GeSe9 by neutron diffraction and first-principles molecular dynamics: Impact of trajectory sampling and size effects

Assil Bouzid

The structure of glassy GeSe9 was investigated by combining neutron diffraction with density-functional-theory-based first-principles molecular dynamics. In the simulations, three different models of N = 260 atoms were prepared by sampling three independen ...

The Bayesian reconstruction of the in-medium heavy quark potential from lattice QCD and its stability

Yannis Burnier

We report recent results of a non-perturbative determination of the static heavy-quark potential in quenched and dynamical lattice QCD at finite temperature. The real and imaginary part of this complex quantity are extracted from the spectral function of W ...
