Design of a Three‐Phase PWM Rectifier Based on Improved Whale Optimization Algorithm Optimized Fuzzy Control

Advanced Control for Applications, Volume 8, Issue 3, September 2026.
Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...

Film Thickness Nonuniformity and the Crucial Role of Water Dosage for Atomic Layer Deposition of Yttrium Oxide

physica status solidi (a), Volume 223, Issue 16, 19 August 2026.
To ensure the expected atomic layer deposition (ALD), this work emphasizes the need to (i) combine local growth kinetics analysis with large‐scale thickness nonuniformity assessment approaches and (ii) carefully select the H2O dosage as well as the process temperature applied to the ALD of Y2O3 from (MeCp)3Y and H2O precursors.

Ultrafast Dynamics of Spin Current and Electron Temperature in Spintronic Terahertz Emitters

Advanced Science, Volume 13, Issue 45, 13 August 2026.
This work quantifies optical‐pump‐induced THz transmission variations to reveal electron and lattice temperature dynamics and presents time‐resolved THz spectral maps for sub‐picosecond analysis. A 63 ± 8 fs time lag between THz emission and laser excitation is identified, serving as an intrinsic parameter limiting the upper frequency of spintronic THz

Tuning the Magnetic Phase Transitions in TbMn2‐xTixSi2 (x = 0–0.3)

Advanced Physics Research, Volume 5, Issue 8, August 2026.
ABSTRACT Magnetocaloric materials receive considerable attention as promising candidates for next‐generation energy‐efficient and environmentally benign solid‐state refrigeration technologies. These materials exhibit the magnetocaloric effect (MCE), whereby heat is absorbed or released upon the application or removal of a magnetic field. In this study,
