Consistent temperature coupling with thermal fluctuations of smooth particle hydrodynamics and molecular dynamics. [PDF]

open access: yesPLoS ONE, 2012
We propose a thermodynamically consistent and energy-conserving temperature coupling scheme between the atomistic and the continuum domain. The coupling scheme links the two domains using the DPDE (Dissipative Particle Dynamics at constant Energy ...

The role of the patch test in 2D atomistic-to-continuum coupling methods [PDF]

open access: yes, 2011
For a general class of atomistic-to-continuum coupling methods, coupling multi-body interatomic potentials with a P1-finite element discretisation of Cauchy–Born nonlinear elasticity, this paper adresses the question whether patch test consistency (or ...

Lossless multi-scale constitutive elastic relations with artificial intelligence

open access: yesnpj Computational Materials, 2022
A seamless and lossless transition of the constitutive description of the elastic response of materials between atomic and continuum scales has been so far elusive. Here we show how this problem can be overcome by using artificial intelligence (AI).

Simulation-Based Defect Engineering in “α-Spodumene”

open access: yesChemEngineering, 2021
Naturally occurring lithium-rich α-spodumene (α-LiAlSi2O6) is a technologically important mineral that has attracted considerable attention in ceramics, polymer industries, and rechargeable lithium ion batteries (LIBs).

Conformational Dependence of the First Hyperpolarizability of the Li@B10H14 in Solution

open access: yesLiquids, 2023
Using the ASEC-FEG approach in combination with atomistic simulations, we performed geometry optimizations of a Cs conformer of the lithium decahydroborate (Li@B10H14) complex in chloroform and in water, which has been shown to be the most stable in the ...

Atomistic-continuum hybrid analysis of dislocation behavior in spinodally decomposed Fe-Cr alloys

open access: yesMATEC Web of Conferences, 2017
In this study, we first present the molecular dynamics (MD) simulation of dislocation behavior in a spinodally decomposed Fe-Cr alloy. The MD simulation is used for exploring the nature of the interaction between a dislocation and the spinodal ...

Defects, diffusion and dopants in Li8SnO6

open access: yesHeliyon, 2021
Octalithium tin (IV) oxide (Li8SnO6) is an important electrode material considered for lithium ion batteries (LIBs) because of its high lithium content.

(In-)stability and stabilisation of QNL-type atomistic-to-continuum coupling methods [PDF]

open access: yes, 2014
We study the stability of ghost force-free energy-based atomistic-to-continuum coupling methods. In 1D we essentially complete the theory by introducing a universally stable a/c coupling as well as a stabilisation mechanism for unstable coupling schemes.

Atomistic Simulation of High-Density Uranium Fuels

open access: yesScience and Technology of Nuclear Installations, 2011
We apply an atomistic modeling approach to deal with interfacial phenomena in high-density uranium fuels. The effects of Si, as additive to Al or as U-Mo-particles coating, on the behavior of the Al/U-Mo interface is modeled by using the Bozzolo-Ferrante-
