Available PhD position at the Division of Mechanics at Lund University

Submitted by Pär Olsson on

The Division of Mechanics at Lund University, Sweden, invites highly motivated and creative applicants for a PhD position oriented towards multiscale modelling of yielding and failure of materials subjected to harsh conditions in energy applications (e.g. components in fusion reactors, battery components, etc.). The research program focuses on improving the understanding of the yielding and failure mechanisms, with the ultimate goal to develop atomistically-informed continuum-based theoretical and computational models to predict yielding and failure in energy materials.

Modeling Uncertainties in Molecular Dynamics Simulations Using A Stochastic Reduced-Order Basis

Submitted by Haoran Wang on

We've recently published our new study about Uncertainty Quantification in Molecular Dynamics (MD) Simulations. Due to the selection of functional forms of interatomic potentials or the numerical approximation, MD simulations may predict different material behavior from experiments or other high-fidelity results. In this study, we used Stochastic Reduced Order Modeling (SROM) to achieve

(1) mechanical behavior of graphene predicted by MD simulations in good agreement with the continuum model which has been calibrated by experiments;

Performing Uniaxial Tensile Tests of Graphene in LAMMPS

Submitted by Nuwan Dewapriya on

I would like to share the codes required to perform an end-to-end molecular dynamics simulation, which will be useful to the novice researchers in the filed of atomistic simulations. I focus on simulating uniaxial tensile tests of a graphene sample in the LAMMPS molecular dynamics simulator, and I have attached two MATLAB scripts to create the input files for LAMMPS and to extract data from the LAMMPS output file.

Carbon nanotube arrays as multilayer transverse flow carbon nanotube membrane for efficient desalination

Submitted by Jingjie Yeo on

https://doi.org/10.1016/j.memsci.2019.03.062 This work presents the multilayer transverse flow carbon nanotube (CNT) membrane (TFCM), which resembles vertically aligned CNT arrays, as an alternative candidate for efficient desalination. Using molecular dynamics, this work shows that multilayer TFCM can provide permeability and salt rejection on par with its single layer counterpart.

Dynamic pigmentary and structural coloration within cephalopod chromatophore organs

Submitted by Jingjie Yeo on

https://doi.org/10.1038/s41467-019-08891-x We report the discovery of structural coloration emanating in precise register with expanded pigmented chromatocytes. Concurrently, using an annotated squid chromatophore proteome together with microscopy, we identify a likely biochemical component of this reflective coloration as reflectin proteins distributed in sheath cells that envelop each chromatocyte.

Multiscale Design of Graphyne‐Based Materials for High‐Performance Separation Membranes

Submitted by Jingjie Yeo on

https://doi.org/10.1002/adma.201805665 Computational modeling and simulations play an integral role in the bottom‐up design and characterization of graph‐n‐yne materials. Here, the state of the art in modeling α‐, β‐, γ‐, δ‐, and 6,6,12‐graphyne nanosheets for synthesizing graph‐2‐yne materials and 3D architectures thereof is discussed. Different synthesis methods are described and a broad overview of computational characterizations of graph‐n‐yne's electrical, chemical, and thermal properties is provided.
