Dynamic Oxygen Species Evolution Boosts Acidic Water Oxidation on W‐Doped RuO2

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Dynamic oxygen species evolution is triggered in tungsten‐doped RuO2 through regulated lattice oxygen diffusion kinetics during acidic oxygen evolution. An optimized oxygen diffusion coefficient balances lattice oxygen participation and vacancy replenishment, driving the transformation from defective low‐coordination sites into a stable six‐coordinated

Characterization of W production during ICRF operations: experiments and modeling

Nuclear Fusion
For successfully heating plasma with waves in the ion cyclotron range of frequencies (ICRFs), mitigating impurity production is just as crucial as maximizing power coupling, especially in high- Z environments (Urbanczyk et al 2021 Nucl. Mater.

Global modelling of tungsten impurity transport based on the drift-kinetic equation

Global modelling of tungsten impurity transport based on the drift-kinetic equation
A global kinetic simulation model of collisional impurity transport is developed for evaluating the radial particle flux of tungsten impurity in the edge region of a tokamak plasma. Here, the plasma including the impurity and the background ion is presupposed to be quasi-steady.
