Resonance ionization spectroscopy of thorium isotopes - towards a laser spectroscopic identification of the low-lying 7.6 eV isomer of Th-229 [PDF]

, 2011
In-source resonance ionization spectroscopy was used to identify an efficient and selective three step excitation/ionization scheme of thorium, suitable for titanium:sapphire (Ti:sa) lasers.

Synergistic damage behavior of He ion irradiation and molten salt corrosion in SiC at 750 °C

Journal of Advanced Ceramics
CVD SiC samples exposed to 400 keV He ion irradiation at 750 °C were subsequently corroded in FLiNaK molten salt at 750 °C for 166 h. After corrosion, the dissolution of Si led to the formation of a carbon-rich layer and obvious denudation of the SiC ...

Thorium Removal, Recovery and Recycling: A Membrane Challenge for Urban Mining

Membranes, 2023
Although only a slightly radioactive element, thorium is considered extremely toxic because its various species, which reach the environment, can constitute an important problem for the health of the population.

Thorium and fetal neural tube defects: an epidemiological evidence from large case-control study

Genes and Environment, 2021
Background Thorium is ubiquitous in the environment and its relationship with birth defects is still under discussion. This study aimed to investigate the associations of maternal exposure to thorium with risk of neural tube defects (NTDs) by using a ...

Thermal transport in thorium dioxide

Nuclear 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 ...

Measurement of the thorium-228 activity in solutions cavitated by ultrasonic sound

, 2009
We show that cavitation of a solution of thorium-228 in water does not induce its transformation at a faster rate than the natural radioactive decay. We measured the activity of a thorium-228 solution in water before, and after, it was subjected to a ...

The unusual role of surface recrystallization on creep damage behavior of GH3535 alloy weld metal

Journal of Materials Research and Technology
It is generally believed that surface recrystallization is detrimental to the mechanical properties of superalloys. However, in our study, surface recrystallization exerts a double-edged effect on the creep damage behavior of GH3535 alloy weld metal at ...
