An Electrowetting Pump

Advanced Functional Materials, Volume 36, Issue 72, 7 September 2026.
A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

A Multimodal Haptic Feedback Interface with Thin‐Film Compliant Mechanism

Advanced Science, Volume 13, Issue 49, 3 September 2026.
Multimodal haptic devices can trigger different mechanoreceptors, enabling richer haptic information. This study presents an electromagnetic multimodal haptic device capable of delivering indentation, stretch, and vibration stimuli. The device is enabled by a novel polymer thin‐film compliant mechanism that provides high translational compliance along ...

Optimization Study of Valve Closing Schemes for Long‐Distance Gravity Flow Water Supply Systems Based on the NSGA‐II Algorithm

Engineering Reports, Volume 8, Issue 9, September 2026.
Taking the Ruyang Water Supply Project of Qianping Reservoir as the research object, a model was built with Bentley Hammer and valve closure schemes were optimized using the NSGA‑II algorithm. Results show that multistage closure is superior to single‑stage, and the optimized three‑stage scheme provides better water hammer protection, offering ...

A Review of Flow Field and Heat Transfer Characteristics of Jet Impingement From Special‐Shaped Holes

Engineering Reports, Volume 8, Issue 9, September 2026.
Special‐shaped nozzles and nanofluid integration enhance jet impingement cooling by improving heat transfer and thermal uniformity. However, gains are constrained by increased pressure drop and stability challenges, highlighting the need for optimized designs and multiscale modeling to achieve efficient, scalable thermal management.

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a
