Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Bistable Wetting States on a Smooth Surface

Advanced Materials Interfaces, EarlyView.
Droplets on non‐textured surfaces typically exhibit a monostable wetting state. Here, we show that droplets can exhibit bistability even without surface texture. We investigate water droplets on a smooth substrate immersed in oil. We find that molecular modulation causes the droplet states to bifurcate into either a sticking or a repellent state ...

Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo

Advanced Materials Interfaces, EarlyView.
Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.

Topological Point Defects in SmC* Liquid Crystals Under Mechanical Disturbance

Advanced Materials Interfaces, EarlyView.
Tangetial air jet shear inducess island formation and nucleates topological point defects in uniform SmC films. Island bounded by edge dislocation loops shrink and transform into isolated point defects under continued shear. Mechanical perturbatio provides a controllable route for defect engineering in smectric liquid crystal thin films.

Study on Passing Performance of a Pig Crossing Pipeline Dent Considering the Fluid Pressure

Shiyou jixie
The passing performance of pig when crossing dented pipeline sections has rarely been studied.Taking the ø168 pipeline pig as an example,3D quasi-static and fluid-solid coupling simulation models of the pig crossing the dented pipeline were built ...
