Extended defects-enhanced oxygen diffusion in ThO2
Miaomiao Jin, Jilang Miao, Beihan Chen +3
Oxygen self-diffusion is key to understanding stoichiometry and defect structures in oxide nuclear fuels. Experimentally, low activation-barrier oxygen migration was found in ThO$_…
Optical pulse induced ultrafast antiferrodistortive transition in SrTiO3
Saqeeb Adnan, Amey Khanolkar, Shuxiang Zhou +2
The ultrafast dynamics of the antiferrodistortive (AFD) phase transition in perovskite SrTiO3 is monitored via time-domain Brillouin scattering. Using femtosecond optical pulses, w…
First-principles determination of the phonon-point defect scattering and thermal transport due to fission products in ThO2
Linu Malakkal, Ankita Katre, Shuxiang Zhou +4
This work presents the first principles calculations of the lattice thermal conductivity degradation due to point defects in thorium dioxide using an alternative solution of the Pi…
Unfaulting mechanisms of Frank loops in fluorite oxides
Miaomiao Jin, Jilang Miao, Yongfeng Zhang +4
Unfaulting of Frank loops in irradiated fluoride oxides are of significance to microstructural evolution. However, the mechanisms have not been directly observed. To this end, we u…
Thermal conductivity suppression in uranium-doped thorium dioxide due to phonon resonant scattering
Zilong Hua, Saqeeb Adnan, Amey R. Khanolkar +7
In this work, the thermal transport properties of thorium dioxide (ThO, thoria) with low levels of substitutional uranium (U) doping are explored. We observe strong indications…
Temperature-dependent elastic constants of thorium dioxide probed using time-domain Brillouin scattering
Amey Khanolkar, Yuzhou Wang, Cody A. Dennett +4
We report the adiabatic elastic constants of single-crystal thorium dioxide over a temperature range of 77 - 350 K. Time-domain Brillouin scattering (TDBS), an all-optical, non-con…
