Modeling and Power Regulation Strategy of Variable‐Speed Pumped Storage Unit With Full‐Size Converter in Pump Mode

Energy Science &Engineering, Volume 14, Issue 5, Page 2393-2413, May 2026.
A numerical model of variable‐speed pumped storage unit (VSPSU) with full‐size converter (FSC) under fast speed control strategy is established. Additionally, the correctness of the model was validated by comparing with SIMSEN simulation results and text prototype data from NARI.

Compositional Gradient–Engineered Ti–WO3 Films for Simultaneous Enhancement of Coloration Efficiency and Mechanical Robustness

Small, Volume 22, Issue 27, 14 May 2026.
A gradient Ti‐doped WO3 electrochromic film is developed via dynamic co‐sputtering, enabling depth‐dependent band engineering and strain regulation. The gradient structure induces a built‐in electric field across the film thickness that enhances coupled ion–electron transport while improving mechanical robustness.
