Design and analysis of extensible differential‐speed helical drive pipe dredging robot
The Journal of Engineering, Volume 2023, Issue 12, December 2023., 2023 The running state of the robot is simulated through virtual prototype technology. The results show that the robot has reasonable structure, comprehensive functions of cutting, stirring and transporting silt, so that the robot is basically in the ‘slurry flow’ condition in the sewer pipe.

The contribution of low‐head pumped hydro storage to grid stability in future power systems
IET Renewable Power Generation, Volume 17, Issue 14, Page 3594-3608, 26 October 2023., 2023 The low‐head PHS system developed in ALPHEUS project will introduce a new storage system. This system will serve as new flexibility option contributing to the security of supply and grid stability with the advantage to provide vital ancillary services, specially frequency control, and thus, promoting the energy transition in the EU.

Directional Bias in Molecular Photogearing Evidenced by LED‐Coupled Chiral Cryo‐HPLC
Angewandte Chemie, Volume 136, Issue 38, September 16, 2024.Significant directionality bias for the coupled rotations of a light‐powered molecular photogear is evidenced by analysis of its enantiomeric states. Using a custom designed LED‐coupled chiral cryo‐HPLC setup, the sense of directionality of coupled double‐ and single bond rotations during photogearing could be elucidated directly.

Crack Propagation in Tooth Root: A Comparison Between Pulsator Test and Running Gears
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 12, Page 5181-5194, December 2025.ABSTRACT Tooth root fatigue fracture is a critical gear failure mode in which the tooth root breaks because of the repetition of bending load. The most widely adopted procedure for evaluating root strength is through pulsator testing. However, this test method does not present gears in meshing conditions. When focusing on the limited‐life region of the
