Bubble Formation in ITER-Grade Tungsten after Exposure to Stationary D/He Plasma and ELM-like Thermal Shocks

Journal of Nuclear Engineering, 2023
Plasma-facing materials (PFMs) in the ITER divertor will be exposed to severe conditions, including exposure to transient heat loads from edge-localized modes (ELMs) and to plasma particles and neutrons.

Cavitation of Electrons Bubbles in Liquid Helium Below saturation Pressure

, 2005
We have used a Hartree-type electron-helium potential together with a density functional description of liquid $^4$He and $^3$He to study the explosion of electron bubbles submitted to a negative pressure.

Indivisibility of Electron Bubbles in Helium

Journal of Low Temperature Physics, 2001
A recent proposal by Maris[1], that single electron bubbles in helium might fission into separate, particle-like entities, does not properly take into account the failure of the adiabatic approximation when, due to tunneling, there is a long electronic time scale. The point along the fission pathway of a photoexcited p-state bubble, where the adiabatic

Resolving Complex Multiscale Structure of Magneto‐ and Electroactive Polymer Composites With an Ionic Liquid

Advanced Materials, EarlyView.
Multiscale ionic liquid segregation into nano‐sized domains in the unconfined amorphous polymer phase and into micron‐sized pores enables a coupled magneto‐ and electroactive responses. ABSTRACT A multiscale understanding of the structure of ionogels – nanoparticle‐free polymer composites incorporating ionic liquids – is essential for enhancing their ...

Molecular dynamics and machine learning study of tensile behavior in single-crystal tungsten containing He bubbles

Materials & Design
Tungsten is commonly used in nuclear fusion plants, where irradiation defects (e.g., He bubbles) are frequently generated. This study investigates the impact of He bubbles on the tensile behavior of single-crystal tungsten through molecular dynamics (MD)

Equation of state for He bubbles in W and model of He bubble growth and bursting near W{100} surfaces derived from molecular dynamics simulations

Scientific Reports, 2023
Molecular dynamics (MD) simulations are performed to derive an equation of state (EOS) for helium (He) bubbles in tungsten (W) and to study the growth of He bubbles under a W(100) surface until they burst. We study the growth as a function of the initial

Density Functional Theory of doped superfluid liquid helium and nanodroplets

, 2017
During the last decade, density function theory (DFT) in its static and dynamic time dependent forms, has emerged as a powerful tool to describe the structure and dynamics of doped liquid helium and droplets.
