We report an ion-irradiation study of a compositionally complex (high-entropy) pyrochlore
oxide. The damage produced from 4 MeV Au 2+ ion irradiation on single crystal (Yb 0.2 Tm …

Glass-ceramics have the potential to be the advanced nuclear wasteforms that can
incorporate radioactive nuclides for a long-term geological disposal. In order to understand …

Gd2Zr2O7 ceramics with different grain sizes ranging from nanoscale to submicron scale
(91, 204, and 634 nm) were irradiated at room temperature using 190 keV He ions with …

First principle calculations based on density functional theory have been employed to study
structural effects of trapping helium in La 2 Zr 2 O 7 pyrochlore. Lattice swelling and the …

Understanding the structure-property relationship for materials destined for irradiation
extremes is a key step in developing materials with reliable, long-term performance. One …

Ionizing events having a wide variety of radiation‐induced effects can radically affect the
kinetics of defect production or structural transformation in the pyrochlore structured oxides …

The influence of A-site vacancies on zirconate perovskite structured ceramics of formula A1−
xLa2x/3ZrO3 (A= Ca, Sr, Ba) has been investigated using 400 keV Kr+ in situ ion irradiation …

The ordered structure A2B2O6O'in pyrochlores engenders twin rows of inequivalent anion
sublattices each centred on alternating cations. While it is known that cation antisite disorder …

Ion implantation using particle accelerators is a promising avenue to emulate the property-
controlling microstructures created in nuclear materials. In the present study, the 21 MeV Au …

Abstract Gadolinium titanate (Gd 2 Ti 2 O 7, or GTO) and other lanthanide pyrochlores are
interesting candidates for actinide waste disposal and fast ion conduction because the …
