Numerical investigation of thermocapillary and buoyancy convection in horizontal ribbon growth with lid-driven boundary

open access: yesAIP Advances, 2020
The melt flow stability has a direct effect on crystal quality during the horizontal ribbon growth (HRG) process. The mixed convection in the HRG system includes thermocapillary convection, buoyancy convection, and the convection induced by the lid ...

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

open access: yesAdvanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

open access: yesAdvanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Thresholds for Atmospheric Convection in Amazonian Rainforests

open access: yesGeophysical Research Letters, 2019
The Amazon rainforest is known as the “Green Ocean” for its maritime‐like convection and cloud microphysics during the wet season. Although previous studies suggest the dominant thermodynamic processes involved in deep convection may differ between land ...
