Thermal transport in thorium dioxide

open access: yesNuclear Engineering and Technology, 2018
In this research paper, the thermal transport in thorium dioxide is investigated by using nonequilibrium molecular dynamics. The thermal conductivity of bulk thorium dioxide was measured to be 20.8 W/m-K, confirming reported values, and the phonon mean ...

Quantifying biological carbon pump pathways with a data-constrained mechanistic model ensemble approach [PDF]

open access: yesBiogeosciences, 2022
The ability to constrain the mechanisms that transport organic carbon into the deep ocean is complicated by the multiple physical, chemical, and ecological processes that intersect to create, transform, and transport particles in the ocean. In this paper
