First principles derivation of a Rayleigh Gans Debye model for scattering from anisotropic inhomogeneities

Scattering problems are important in describing light propagation in wide ranging media such as the atmosphere, colloidal solutions, metamaterials, glass ceramic composites, transparent polycrystalline ceramics, and surfaces. The Rayleigh Gans Debye

Bulk Polycrystalline Ceria Doped Al$_2$O$_3$ and YAG Ceramics for High-Power Density Laser-Driven Solid-State White Lighting: Effects of Crystallinity and Extreme Temperatures

Autor: Penilla, E. H., Sellappan, P., Duarte, M. A., Wieg, A. T., Wingert, M., Garay, J. E.

Here we develop and characterize high thermal conductivity/high thermal shock resistant bulk Ce doped Al2O3 and propose it as a new phosphor converting capping layer for high-powered/high-brightness solid-state white lighting (SSWL). The bulk, dense

Magnetic and Thermal Transport Properties of Permanent Magnets with Anisotropic Grain Structure

Autor: Volodchenkov, A. D., Ramirez, S., Samnakay, R., Salgado, R., Kodera, Y., Balandin, A. A., Garay, J. E.

Publikováno v: Materials and Design, 125, 62 (2017)

Nanostructured permanent magnets are gaining increasing interest and importance for applications such as generators and motors. Thermal management is a key concern since performance of permanent magnets decreases with temperature. We investigated the

Thermal and Magnetic Properties of Nanostructured Ferrimagnetic Composites with Graphene - Graphite Fillers

Autor: Ramirez, S., Chan, K., Hernandez, R., Recinos, E., Hernandez, E., Salgado, R., Khitun, A. G., Garay, J. E., Balandin, A. A.

Publikováno v: Materials and Design, 118, 75 (2017)

We report the results of an experimental study of thermal and magnetic properties of nanostructured ferrimagnetic iron oxide composites with graphene and graphite fillers synthesized via the current activated pressure assisted densification. The ther

Synthesis of strontium ferrite/iron oxide exchange coupled nano-powders with improved energy product for rare earth free permanent magnet applications

Autor: Volodchenkov, A. D., Kodera, Y., Garay, J. E.

We present a simple, scalable synthesis route for producing exchange coupled soft/hard magnetic composite powder that outperforms pure soft and hard phase constituents. Importantly, the composites is iron oxide based (SrFe12O19 and Fe3O4) and contain
