Achieving Anti-Disproportionation Performance Enhancement and Distorted Inverse-Disproportionation Reaction Correction of Zr<sub>2</sub>Fe-Based Hydrogen Isotope Storage Alloys via Element Substitution. [PDF]

open access: yesAdv Sci (Weinh)
Undesirable phase transition behavior and anti‐disproportionation performance limit the hydrogen isotope storage of Zr2Fe alloy. With theoretical screening and experiments, partial Cu/Ni substitutions achieve full reversibility and significantly improve anti‐disproportionation properties.

High Radiation Resistance in the Binary W-Ta System Through Small V Additions: A New Paradigm for Nuclear Fusion Materials. [PDF]

open access: yesAdv Sci (Weinh)
Refractory high‐entropy alloys exhibit superior radiation tolerance, but face fabrication challenges due to complex compositions. It is demonstrated that reducing the number of alloying elements does not compromise radiation resistance in a novel W‐Ta‐V highly‐concentrated refractory alloy.

Artificial Intelligence and Nuclear Weapons Proliferation: The Technological Arms Race for (In)visibility. [PDF]

open access: yesRisk Anal
ABSTRACT A robust nonproliferation regime has contained the spread of nuclear weapons to just nine states. Yet, emerging and disruptive technologies are reshaping the landscape of nuclear risks, presenting a critical juncture for decision makers. This article lays out the contours of an overlooked but intensifying technological arms race for nuclear ...

THIN NITRIDE LAYERS AS PERMEATION BARRIERS

open access: yesActa Polytechnica CTU Proceedings, 2018
Permeation barriers represent one of the crucial fields in materials development for thermonuclear fusion. Primary objective of the barriers is to suppress the permeation of hydrogen isotopes (mainly tritium) from future thermonuclear fusion facilities ...

Important problems of future thermonuclear reactors*

open access: yesNukleonika, 2015
This paper concerns important and difficult problems connected with a design and construction of thermonuclear reactors, which have to use nuclear fusion reactions of heavy isotopes of hydrogen, i.e., deuterium (D) and tritium (T).
