Workshop on Coarse-Grained Modeling of Polymers and Soft Materials for the Materials Genome Initiative

Low resolution coarse-grained (CG) models are widely adopted for investigating soft materials. Nevertheless, it remains challenging to determine CG models that accurately describe both structure and thermodynamic properties. In this talk, we discuss a variational method for determining accurate models directly from structural information via a generalized-Yvon-Born-Green (g-YBG) theory that is ...

Materials Science Initiative Seminar: Materials for Tomorrow

Phase-field method and Materials Genome Initiative (MGI)

Predicting and controlling the microstructure evolution within a material are considered as the ‘‘holy grail’’ of materials science and engineering. Many important engineering materials are designed by controlling their phase transformations and microstructure evolution. Examples include the improvement of mechanical properties through solid-state precipitation reactions in Nibased superalloys ...

Advancing the Materials Genome

The term, Materials Genome (a registered trademark of MaterialsGenome, Inc., Pennsylvania, USA) was coined by the present author in 2002 and recently used with consent in the “Materials Genome Initiative” by the White House Office of Science and Technology Policy. In this paper, the author’s perspectives on Materials Genome, i.e. the building blocks of materials, will be illustrated with severa...

The comparison between simple and advanced shielding materials for the shield of portable neutron sources

Background: Monte Carlo simulations play a vital role in the calculation of the necessary shielding both for neutrons and photons. Advanced and simple shielding materials against neutron and gamma rays were compared by simulation using the MCNB4B Monte Carlo code. The simulations were carried out for the three common neutron sources, namely the 252Cf, the 241Am/Be and the DD neutron generator w...
