Discrete modelling of the dual active bridge converter
, 2022 Bidirekskjonelle DC-til-DC omformere spiller en meget viktig rolle i dagens elektriske energi infrastruktur. Ettersom distribuerte ressurser har blitt en aktiv del av elnettverket, evnen til å sende kraft til-og fra last muliggjør en mer effektiv og fkeksibel utnyttelse av infrastrukturen i sin helhet, og hovedsakelig av smartgrid konseptet.

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring
Advanced Functional Materials, EarlyView.This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Advanced Functional Materials, EarlyView.Ferroelectric nematic liquid crystals (FNLCs) offer fast, tunable polarization and low‐voltage operation but suffer from poor polarization retention at zero field. Semiconductor‐modified FNLCs enhance polarization retention and exhibit short‐ and long‐term electro‐optical responses, while also supporting spike‐type signal integrations.
