Spontaneous Motion of Liquid Droplets on Soft Gradient Surfaces
Weiwei Zhao, Wenjie Qian, Chang Xu +1
We report an experimental investigation of the spontaneous motion of liquid droplets on soft gels with a crosslinking gradient. By systematically adjusting the spatial difference i…
Emergence and Growth Dynamics of Wetting-induced Phase Separation on Soft Solids
Wenjie Qian, Weiwei Zhao, Tiezheng Qian +1
Liquid droplets on soft solids, such as soft polymeric gels, can induce substantial surface deformations, leading to the formation of wetting ridges at contact points. While these…
Non-monotonic Rheology and Stress Heterogeneity in confined Granular suspensions
Haitao Hu, Yiqiu Zhao, Weiwei Zhao +2
We systematically investigated the impact of boundary confinement on the shear-thickening rheology of dense granular suspensions. Under highly confined conditions, dense suspension…
The role of crosslinking density in surface stress and surface energy of soft solids
Weiwei Zhao, Jianhui Zhou, Haitao Hu +2
Surface stress and surface energy are two fundamental parameters that determine the surface properties of any materials. While it is commonly believed that the surface stress and s…
