Deuterium plasma exposure of thin oxide films on tungsten - oxygen removal and deuterium uptake
Nuclear Materials and Energy, 2023 Recently we have shown that thin (33 to 55 nm) oxide films on tungsten (W) prevent deuterium (D) uptake from a low-temperature plasma (5 eV/D; 370 K; 1.4 × 1024 D/m2) into metallic W.

Air contamination and its effect on deuterium desorption in liquid lithium
Nuclear Materials and Energy, 2023 The clean wall condition in tokamak devices can be achieved by utilizing the active chemical property of lithium (Li). This also exposes Li to air contamination even when protected by inert gas.

The neglected activation of tantalum in reduced activation materials
Nuclear Materials and Energy, 2023 Due to the expression of “reduced activation”, the severe radioactivity of tantalum (Ta) after neutron irradiation in early decay years is easily neglected. In the presented study, after an irradiation of only 0.3 dpa by fission neutron and followed by a
