Computer Graphics Forum, Volume 44, Issue 3, June 2025.Abstract We introduce a fast and invertible approximation for fusion plasma simulation data represented as 2D planar meshes with connectivities approximating magnetic field lines along the toroidal dimension in deformed 3D toroidal spaces. Scientific variables (e.g., density and temperature) in these fusion data are interpolated following a complex ...

Formation of a Boron‐Oxide Termination for the (100) Diamond Surface
Advanced Materials Interfaces, Volume 11, Issue 33, November 25, 2024.A boron‐oxide termination for (100) diamond is formed under ultrahigh vacuum conditions. This is the first demonstration of a new method of introducing a boron‐based species to the diamond lattice. This result has potential for enabling new surface‐based pathways to the fabrication of high quality boron‐doped delta layers and boron‐based material ...

Methods for Color Center Preserving Hydrogen‐Termination of Diamond
Advanced Materials Interfaces, Volume 11, Issue 24, August 23, 2024.Hydrogen‐termination of diamond by three methods. Hydrogen plasma exposure with stage heating above 700 °C yields maximal coverage but causes irr loss of shallow nitrogen‐vacancy fluorescence. Plasma exposure without heating preserves nitrogen‐vacancies at the expense of increased oxygen coverage.

Near-surface expansion of vacuum stellarator configurations
Nuclear FusionStellarators are inherently steady-state and disruption-free. However, three-dimensional geometry significantly increases the complexity of both equilibrium calculation and configuration optimization.

Contributions to Plasma Physics, Volume 64, Issue 7-8, August-September 2024.Abstract The distribution pattern of the connection length in the divertor region of Heliotron J was calculated by the field line tracing method. A multifold layer structure, characterized by the range of connection length, was revealed to interpret the response of the transport of the lower‐charged impurity ions to the divertor structure.

Toward plasma drifts in EMC3: Implementation of gradient, divergence, and particle tracing schemes
Contributions to Plasma Physics, Volume 64, Issue 7-8, August-September 2024.Abstract This paper presents a first implementation of gradient, divergence, and particle tracing schemes for the EMC3 code, a stochastic 3D plasma fluid code widely employed for edge plasma and impurity transport modeling in tokamaks and stellarators.

International Journal of Energy Research, Volume 2024, Issue 1, 2024.The present research presents an innovative approach by integrating magnetohydrodynamic (MHD) flow with resistive heating, integrating a partly permeable layer and interior heat production to scrutinize natural convective flow within a square domain. It also examines both straight and wavy interfaces between the porous and fluid domains.
