Nanostructured materials contain an extremely high density of interfaces. The properties of
these materials when exposed to extreme conditions of radiation dose, stress, deformation …

We review the state of first-principles density functional theory (DFT) modeling of nuclear
fuel materials. DFT-based first-principles modeling has emerged as a quantitatively rigorous …

Radiation damage tolerance for a variety of ceramics at high temperatures depends on the
material's resistance to nucleation and growth of extended defects. Such processes are …

Pyrochlores, a class of complex oxides with formula A2B2O7, are one of the candidates for
nuclear waste encapsulation, due to the natural occurrence of actinide-bearing pyrochlore …

Amorphous hafnia (HfO 2) powders were synthesized through a novel reduction–oxidation
route, in which, metal hafnium was reduced from hafnium tetrachloride (HfCl 4) by sodium …

Due to reduced dimensions and increased interfacial content, nanocomposite oxides offer
improved functionalities in a wide variety of advanced technological applications, including …

Nanometric-sized yttrium doped HfO2 powders were obtained by applying metathesis and
combustion reactions. The tailored composition of solid solutions was: Hf1− xYxO2− δ with …

Four-phase ceramic composites containing 3 mol% Y 2 O 3 stabilized ZrO 2 (3Y-TZP), Al 2 O
3, MgAl 2 O 4, and LaPO 4 were synthesized as model materials representing inert matrix …

This study investigates the temperature dependent thermal conductivity of multiphase
ceramic composites for simulated inert matrix nuclear fuel. Fine grained composites were …

Oxide composites are a class of materials with potential uses for nuclear, space, and coating
applications. Exploiting their promise, however, requires a detailed understanding of their …
