In Situ Sintering Studies of Reactive Sintered Borides (RSB) Neutron Shielding Materials

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT Reactive sintered borides (RSBs) are a family of radiation‐dense materials made by powder metal processing and sintering of elemental precursors. Recent interest in RSBs has focused on their properties as high‐flux low‐activation thermal neutron absorbers for nuclear applications including fusion reactors.

Fluctuating Interfaces in Barotropic Beta‐Plane Turbulence

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Zonal jets manifest themselves as bands with sharp interfaces in the vorticity configuration. We develop an algorithm to track these fluctuating vorticity interfaces and systematically investigate their characteristic spatio‐temporal behaviors.

Stress, strain, neutron transport and radiation effects in a full fusion tokamak device: A virtual MAST-U study [PDF]

EPJ Web of Conferences
A finite-element method (FEM) model for the Mega-Ampere Spherical Tokamak - Upgrade (MAST-U) fusion tokamak has been developed to evaluate stress and deformations in the full device structure and to assess the stability of the whole tokamak with respect ...

Design and construction of magnetic diagnostics on NanChang spherical tokamak

AIP Advances, 2022
The NanChang Spherical Tokamak (NCST) is a new compact tokamak (with an aspect ratio of R/a = 1.67) for exploring the merging compression by which the plasma start-up is highly efficient.

Auroral Signatures of Ballooning Instability and Plasmoid Formation Processes in the Near‐Earth Magnetotail

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The nonlinear development of ballooning instability and the subsequently induced plasmoid formation in the near‐Earth magnetotail demonstrated in MHD simulations has been proposed as a potential trigger mechanism for substorm onset over the past decade, and their connections to the in situ satellite and ground all‐sky auroral optical ...

Data readiness pipeline patterns for scientific AI at scale: Insights from climate, fusion, life sciences, and materials

AI Magazine, Volume 47, Issue 1, Spring 2026.
Abstract This article examines how data readiness for AI principles apply to large scientific datasets used to train foundation models. We analyze archetypal workflows across four representative domains—climate, nuclear fusion, life sciences, and materials—to identify common preprocessing patterns and domain‐specific constraints.

Relaxation Phenomena in Spherical Tokamak Plasma [PDF]

Progress of Theoretical Physics Supplement, 2000
Dynamics of a relaxation phenomenon observed in Spherical Tokamak experiments, which is called Internal Reconnection Event (IRE), is studied by magnetohydrodynamic computer simulation. Coupling between the torus magnetic field and the external field induced by nonlinear growth of pressure driven instabilities, and resultant formation of tunnel-like ...

Relation between porosity‐based and crystal‐based femtosecond laser‐induced nanogratings in oxide glasses

International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.
Abstract Femtosecond laser irradiation in glass, under controlled conditions, can induce two types of nanogratings (NG): porous nanogratings (pNG) and crystal/glass nanogratings (cNG). While most glasses exhibit only one type, binary aluminosilicate glasses have shown both types of NG.

A Review of Multilevel Decision and Game‐Theoretic Approaches to Nuclear Technology Innovation Management for Sustainable Energy Transitions

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Nuclear technology innovation management plays a key role in the global energy transition and the development of low‐carbon economy. This paper, as a comprehensive review, systematically discusses the complex decision‐making process in nuclear technology innovation, based on the framework of multilevel decision theory and game theory.
