Heat Load Mitigation Studies in the W7‐X Stellarator Experiment

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT During the experiments at the stellarator Wendelstein 7‐X (W7‐X) with fully water‐cooled plasma‐facing components (PFC), including carbon‐fiber composite (CFC) divertor targets with a thermal load capability of 10 MW/m2, high performance was achieved.

Inductive MHD Generator

open access: yesZeitschrift für Naturforschung A, 1963
The electrodynamic response of a particular inductive magnetohydrodynamic generator is calculated. Expressions for the output voltage and output power are derived. The results of experiments conducted with the generator mounted on an electromagnetic shock-tube agree with the theoretical predictions. The measured output power is of the order of 10 watts

Magnetic Electrocatalysts Enabling a High‐Rate Capability in Lithium‐Oxygen Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces zinc ferrite (ZnFe2O4) nanoparticles with tunable magnetic properties as bifunctional electrocatalysts for lithium‐oxygen batteries. Under an applied magnetic field, these catalysts significantly enhance oxygen reduction and evolution reactions by promoting spin‐aligned charge transfer and ion diffusion. The approach achieves high
