Structure-Force Field Generator for Molecular Dynamics Simulations
07 Aug 2017 | | Contributor(s):: Carlos Miguel Patiño, Lorena Alzate-Vargas, Alejandro Strachan
Atomistic and molecular simulations have become an important research field due to the progress made in computer performance and the necessity of new and improved materials. Despite this, first principle simulations of large molecules are still not possible because the high computational time...
Multiscale Modelling of Nanoparticle Suspensions
12 Jun 2017 | | Contributor(s):: Pietro Asinari
In the present work a multiscale modelling approach is implemented to relate the nanoscale phenomena to the macroscopic bulk properties of nano-suspensions. Specifically, Molecular Dynamics (MD) simulations and Brownian Dynamics (BD) are synergistically integrated to understand the mechanisms...
Polymer Synthesis and Characterization in the Cloud: a nanoHUB Classroom Experience
22 Jan 2016 | | Contributor(s):: Coray Colina
In this talk, I’ll share the experience of teaching a junior undergraduate computational course in materials science and engineering, with over 70 participants. Both molecular and continuum methods were studied and applied to relevant materials problems. Students were able to build and...
Atomistic Modeling: Past, Present, and Future, MGI, ICME, etc.
03 Nov 2015 | | Contributor(s):: Paul Saxe
I will present a perspective on atomistic modeling — tools using quantum methods such as DFT, as well as molecular dynamics and Monte Carlo methods based on forcefields — over the past 30 years or so. While we are all caught up in the present, it is important to remember and realize...
Introduction to Molecular Dynamics

21 Apr 2015 | | Contributor(s):: Alejandro Strachan
This short presentation will describe the idea behind MD simulations and demonstrate its use in real applications.
MSE 498 Lesson 10: MD
17 Mar 2015 | | Contributor(s):: Andrew Ferguson
This new course will give students hands-on experience with popular computational materials science and engineering software through a series of projects in: electronic structure calculation (e.g., VASP), molecular simulation (e.g., GROMACS), phase diagram modeling (e.g., Thermo-Calc), finite...

IMA 2013 UQ: Bayesian Calibration of Molecular Dynamics Simulations for Composite Materials Properties
28 May 2014 | | Contributor(s):: Paul N. Patrone
In this talk, I discuss ongoing research whose goal is to determine, via Bayesian inference, an ensemble of inputs that represents a class of commercially important amine-cured epoxies. We construct an analytical approximation (i.e. a surrogate or emulator) of the simulations, treating the input...
IMA 2013 UQ: DFT-based Thermal Properties: Three Levels of Error Management
02 Apr 2014 | | Contributor(s):: Kurt Lejaeghere
It is often computationally expensive to predict finite-temperature properties of a crystal from density-functional theory (DFT). The temperature-dependent thermal expansion coefficient α, for example, is calculated from the phonon spectrum, and the melting temperature Tm can only be obtained...

[Illinois] Beckman Graduate Seminar: Membrane Sculpting by F-BAR Domains Studied by Molecular Dynamics Simulations
18 Dec 2012 | | Contributor(s):: Hang Yu
Interplay between cellular membranes and their peripheral proteins drives many processes in eukaryotic cells. Proteins of the Bin/Amphiphysin/Rvs (BAR) domain family, in particular, play a role in cellular morphogenesis, for example curving planar membranes into tubular membranes. However, it is...
[Illinois] CSE Seminar Series: Advances in First-principles Computational Materials Science
20 Nov 2012 | | Contributor(s):: Elif Ertekin
Title: Advances in first-principles computational materials scienceSubtitle: Things we can calculate now, that we couldn't when I was in grad school.The capability to rationally design new materials with tailored properties and functionality on a computer remains a grand challenge whose success...

MD Simulations of Gas Flows in Nano-Channels and Interface Thermal Resistance Between Simple Liquids and Solids
31 May 2012 | | Contributor(s):: Ali Beskok
This talk focuses on our group’s recent research on molecular dynamics simulations of gas flows in nano-scale confined geometries, and interface thermal resistance between simple liquids and solids. Gas flow research demonstrates the importance of wall force field effects that penetrate...
