Post‐Shaping Over‐Impregnation: A Facile Strategy for Pt‐KL Catalysts With Ultrahigh Metal Dispersion and Enhanced Aromatization Performance

open access: yesCarbon and Hydrogen, Volume 28, Issue 2, Page 196-208, June 2026.
A scalable post‐shaping strategy achieves precise Pt localization within KL zeolite, where optimized spatial distribution minimizes diffusion barriers to deliver superior n‐hexane aromatization activity, selectivity, and stability. ABSTRACT The precise localization of metal clusters within zeolite frameworks is critical for the aromatization catalysis.

Coordinated DC Fault Ride‐Through Control for a Grid‐Forming Wind‐Storage System With VSC‐HVDC Integration Under Transmission Constraints

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
Due to complex wind farm conditions, a coordinated control system was designed. It manages DC power surges during AC faults by temporarily storing excess energy and regulating voltages. This strategy optimizes unbalanced power and enables effective fault recovery, resulting in minimal voltage fluctuations and superior performance.
