Mimicking Life: Autonomous Oscillating Artificial Cilia Driven by Chemical Power

open access: yesAdvanced Intelligent Systems, EarlyView.
The synthesis and motion analysis of chemically actuated, individually autonomous artificial cilia are presented. Driven by an internal chemical reaction, the self‐driven individual cilia require no external stimuli. They undergo periodic oscillatory motion with a 3D beat pattern and exhibit chemotactic shifts, reminiscent of biological systems.

Worm‐Inspired Soft Robots With Modular Outfit‐Changing for Intelligent Multienvironment Adaptation

open access: yesAdvanced Intelligent Systems, EarlyView.
This study proposes a worm‐inspired soft robot capable of locomotion across multiple environments through a modular “outfit‐changing” strategy. The robot integrates pneumatically actuated peristaltic segments with interchangeable external modules, enabling efficient motion on ground surfaces, within pipelines, through granular media, and underwater ...

Numerical Analysis of Proton Exchange Membrane Fuel Cell Performance With a Lung Serpentine Flow Field

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Proton exchange membrane fuel cells (PEMFC) are regarded as the best clean energy conversion technology because of their smaller number of emissions and higher efficiency. This numerical investigation used two different flow channel designs—the serpentine flow field (SFF) and the lung serpentine flow field (LSFF)—with active areas of 5 by 5 cm.

Numerical Optimization of a Hybrid Cooling System for Lithium‐Ion Battery Packs: PCM‐Assisted and Liquid Cooling Integration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a hybrid cooling system design that constructs a phase change material (PCM) filled layer between a liquid cooling jacket and cylindrical battery cells, combining the advantages of efficient liquid cooling and passive temperature control from PCM. The system performance was optimized through numerical simulation.
