Explore the growing power of molecular simulations to address a variety of problems.

In 60 minutes, you’ll delve into the basics of molecular simulations and see examples of their applications to simulations of surfactants, lipids and polymers. You’ll consider the range of time and length scales now accessible with both atomistic and coarse-grained simulations, primarily molecular dynamics, and the kinds of problems that can now be addressed. You’ll learn about the use of sampling methods, in particular the Histogram Weighted Analysis Method. You’ll review the results using standard atomistic force fields - such as GROMOS, CHARMM, OPLS and others - and using standard coarse-grained force fields - such as Martini, Dry Martini and the SDK model. This webinar will address problems that include the dynamics of lipid monolayers and bilayers, lung surfactant layers - including the effect of peptides - surfactant self-assembly and micelle shape transitions, the interactions of surfactants with water-oil interfaces, the dynamics of components of latex coatings - such as polymer thickeners - and the interactions of dendrimers with DNA.

Take a look at your agenda:

  • Understand the basics of molecular simulation, including the use of simulation engines and force fields
  • Know the most common and popular atomistic and coarse-grained molecular dynamics force fields
  • Identify the range of length and time scales accessible by molecular simulations
  • How sampling methods are used to determine free energies
  • What can be learned from molecular simulations, using example problems drawn from industrial problems and biology

Dr. Larson earned his BS, MS, and PhD in chemical engineering from the University of Minnesota. He worked for 17 years at Bell Laboratories (Murray Hill, NJ) before joined the University of Michigan (UM) faculty in 1996. There, his research interests have included the structure and flow properties of complex fluids, which include polymers, colloids, surfactant-containing fluids, and biological macromolecules. He has also served as Chair of UM’s Chemical Engineering Department.

He is a recipient of AIChE’s Alpha Chi Sigma Award for Chemical Engineering Research (2000), the...Read more
