1. Workshop Report:
Building the Materials Innovation Infrastructure: Data and Standards A Materials Genome Initiative
NIST Interagency/Internal Report (NISTIR)
James A Warren, Ronald F Boisvert
The Materials Genome Initiative (MGI) is a multi-agency, multi-stakeholder effort to develop the
infrastructure needed to enable the materials science community to discover, develop, manufacture,
and deploy advanced materials at least twice as fa ...
2. A diffuse-interface Model of Reactive Wetting with Intermetallic Formation
Walter Villaneuva, William J Boettinger, Geoffrey B McFadden, James A Warren
A diffuse-interface model of reactive wetting with intermetallic formation is developed that incorporates fluid flow, phase change, and solute diffusion. The model is based on the total molar Gibbs energy of a ternary system with four phases. Numeric ...
3. The Effect of Substrate Material on Silver Nanoparticle Antimicrobial Efficacy
Benita Dair, Dave M. Saylor, T. Eric Cargal, Grace R. French, Kristen M. Kennedy, Rachel S. Casas, Jonathan E Guyer, James A Warren, Steven K. Pollack
With the advent of Nanotechnology, silver nanoparticles increasingly are being used in coatings, especially in medical device applications, to capitalize on their antimicrobial properties. The increased antimicrobial efficacy of nanoparticulate silv ...
4. Predicting Microstructure Development During Casting of Drug Eluting Coatings
David M. Saylor, Jonathan E Guyer, Daniel Wheeler, James A Warren
We have devised a novel diﬀuse interface formulation to model the development of chem-
ical and physical inhomogeneities, i.e. microstructure, during the process of casting drug
eluting coatings. These inhomogeneities, which depend on the ...
5. Modeling Solvent Evaporation During the Manufacture of Controlled Drug Release Coatings and the Impact on Release Kinetics
James A Warren, D M. Saylor, Martin McDermott, D Patwardhan, Chang-Soo Kim
To improve functionality and performance, controlled drug release coatings comprised of
drug and polymer are integrated with traditional medical devices, e.g. drug eluting stents.
Depending on manufacturing conditions, these coatings can exhibit ...
6. Grain boundaries exhibit the dynamics of glass-forming liquids
James A Warren, Jack F Douglas, Hao Zhang, David J Srolovitz
Polycrystalline materials are composites of crystalline particles or grains separated by thin amorphous grain boundaries (GBs). Although GBs have been exhaustively investigated at low temperatures, at which these regions are relatively ord ...
7. FiPy: PDEs in Python
Jonathan E Guyer, Daniel Wheeler, James A Warren
equations (PDEs) are ubiquitous to the mathematical description of physical
phenomena. They describe the relationships between functions of more than
one independent variable and partial derivatives with respect to those
8. Modeling Microstructure Development and Release Kinetics in Controlled Drug Release Coatings.
D M. Saylor, James A Warren
9. Phase Field Approach to Heterogeneous Crystal Nucleation in Alloys
James A Warren, T Pusztai, L Kornyei, L Granasy
We extend the phase field model of heterogeneous crystal nucleation developed recently [L. Granasy, T. Pusztai, D. Saylor, and J. A. Warren, Phys. Rev. Lett. 98, 035703 (2007)] to binary alloys. Three approaches are considered to incorporate foreign ...
10. An Efficient Algorithm for Solving the Phase Field Crystal Model
Mowei Cheng, James A Warren
We present and discuss the development an unconditionally stable algorithm to solving the evolution equations for the Phase Field Crystal (PFC) model. This algorithm allows for an arbitrarily large algorithmic time step. As the basis for our analys ...
