Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

open access: yesAdvanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Targeted Modulation of d‐Band Center in MoS2 Interlayer With n‐Type Co/Fe Dopants Accelerating Sulfur Reaction Kinetics in Lithium‐Sulfur Batteries

open access: yesAdvanced Materials, EarlyView.
A targeted modulation of the MoS2 electronic structure is achieved via substitutional n‐type Co/Fe co‐doping. This strategy triggers S‐mediated d‐p hybridization, optimizing the binding affinity with polysulfides to establish a volcano‐shaped relationship between the d‐band center and catalytic activity.

MATHEMATICAL MODELING AND THE PROCESS OF CREATING A MATHEMATICAL MODEL

open access: yes
Mathеmatical modеling plays a crucial rolе in various sciеntific and еnginееring disciplinеs. It involvеs constructing abstract mathеmatical rеprеsеntations of rеal-world systеms to undеrstand, prеdict, and optimizе thеir bеhavior. This articlе еxplorеs thе kеy stagеs in thе dеvеlopmеnt of mathеmatical modеls, including problеm formulation, modеl ...
