Thorium amidates function as single-source molecular precursors for thorium dioxide [PDF]

, 2021
We report the synthesis of four homoleptic thorium(iv) amidate complexes as single-source molecular precursors for thorium dioxide. Each can be sublimed at atmospheric pressure, with the substituents on the amidate ligands significantly impacting their ...

Thermal Transport Behavior of Graphite Coated Thorium Dioxide [PDF]

, 2021
At present 14% of the world’s energy is generated from nuclear reactors, while in the United States this is 20% of all energy produced. As the world moves to more renewable and cleaner energy sources, nuclear energy becomes a more favorable candidate for

Valence electronic state density in thorium dioxide [PDF]

Nuclear Technology and Radiation Protection, 2008
This work analyses the fine low energy (0-40 eV) X-ray photoelectron spectra of ThO2, taking into account relativistic Xα-discrete variation electronic structure calculations for the ThO8 (D4h) cluster reflecting thorium's close environment in ThO2. As a

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

Biogeosciences, 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

The influence of lattice defects, recombination, and clustering on thermal transport in single crystal thorium dioxide

APL Materials, 2020
Thermal transport is a key performance metric for thorium dioxide in many applications where defect-generating radiation fields are present. An understanding of the effect of nanoscale lattice defects on thermal transport in this material is currently ...

A molecular dynamics study of the thermal properties of thorium oxide [PDF]

, 2012
There is growing interest in the exploitation of the thorium nuclear fuel cycle as an alternative to that of uranium. As part of a wider study of the suitability of thorium dioxide (thoria) as a nuclear fuel, we have used molecular dynamics to ...

How does dynamical spatial variability impact 234Th-derived estimates of organic export? [PDF]

, 2012
In this study we first evaluate the small-scale spatial variability of particulate export, using a set of synoptic thorium-234 activity observations sampled within a one-degree radius.
