Published in 2019 at "International Journal of Hydrogen Energy"

DOI: 10.1016/j.ijhydene.2019.08.253

Abstract: Abstract In this work, we discuss the effect of multiphase flow dynamics on the performance of a PEM electrolyzer. We obtained images of a flow system consisting of O2 and water at two stages of… read more here.

DOI: 10.1016/j.jmapro.2018.12.020

Abstract: Abstract The evolution mode of the dynamic bubble around the arc burning zone plays an essential role in adversely affecting the stability of underwater wet welding (UWW) process. Ultrasonic wave-assisted UWW (U-UWW) provides such a… read more here.

Published in 2018 at "Journal of Nuclear Materials"

DOI: 10.1016/j.jnucmat.2018.04.051

Abstract: Abstract A multiscale model of helium bubble evolution in plasma-facing materials is developed. The model links different stages of helium bubble evolution: deposition, nucleation, growth, motion, and coalescence. Helium deposition is simulated with the SRIM… read more here.

Published in 2019 at "Journal of Nuclear Materials"

DOI: 10.1016/j.jnucmat.2019.02.004

Abstract: Abstract The microstructure investigations of a U3Si2 specimen implanted by 84 MeV Xe ions at 450∘C are reported here. In the region that corresponds to the highest irradiation dose, U3Si2 was found to decompose into a… read more here.
