Layered Double Hydroxides as Cation Exchange Materials

October 12, 2021
Author(s)
Paul Braterman, Nandika A. D'Souza, Jeffrey W. Gilman, Mickey C. Richardson, Laxmi K. Sahu, Mauro Zammarano
Layered double hydroxides (LDH) are a class of materials formally related to brucite-like hydroxides by the incorporation of higher valent cations, such as Al(III). The layer charge is neutralized by the insertion of any of a large range of exchangeable

MatML: XML for Information Exchange With Materials Property Data

October 12, 2021
Author(s)
A S. Varde, E F. Begley, S Fahrenholz-Mann
This paper describes the development and use of MatML, the Materials Markup Language. MatML is an emerging XML standard intended primarily for the exchange of materials property information. It provides a medium of communication for users in materials

Measuring Tip Shape for Instrumented Indentation Using Atomic Force Microscopy

October 12, 2021
Author(s)
Mark R. VanLandingham, John S. Villarrubia, R M. Camara
Atomic Force Microscopy (AFM) was used to determine the three-dimensional shape of probe tips used for instrumented indentation. AFM images were taken for three probe tips with several different image sizes. The geometry obtained directly from the images

Molecular Modeling of the Thermal Decomposition of Polymers

October 12, 2021
Author(s)
S I. Stoliarov, H Zhang, P R. Westmoreland, R Lyon, Marc R. Nyden
Applications presented in this work demonstrate the potential for using quantum mechanics and molecular simulations to determine the mechanisms and rates of the thermal decomposition of polymers. The expectation is that these capabilities can be used to

Optical Probes for Monitoring Intercalation and Exfoliation in Melt Processed Polymer Nanocomposites

October 12, 2021
Author(s)
P H. Maupin, Jeffrey W. Gilman, Richard H. Harris Jr., S Bellayer, Anthony J. Bur, S C. Roth, A B. Morgan, J R. Harris, M Murariu
Laser induced fluorescence spectroscopy of the optical probe Nile Blue A in polymer clay nanocomposites is described. Concentration quenching of fluorescence dominates probe behavior until the clay platelets are physically separated by polymer
