Fish, seaweed inspire slippery surfaces for ships
Fish and seaweed secrete a layer of mucus to create a slippery surface, reducing their friction as they travel through water. A potential way to mimic this is by creating lubricant-infused surfaces covered with cavities. As the cavities are continuously filled with the lubricant, a layer is formed over the surface. In the journal Physics of Fluids, researchers in South Korea conducted simulations of this process to help explain the effects. (2020-09-15)

Why is ice so slippery
The answer lies in a film of water that is generated by friction, one that is far thinner than expected and much more viscous than usual water through its resemblance to the 'snow cones' of crushed ice we drink during the summer. This phenomenon was recently demonstrated by researchers from the CNRS and ENS-PSL, with support from the École polytechnique, in a study that appeared in Physical Review X on Nov. 4, 2019 (2019-11-05)

Stabilizing multilayer flows may improve transportation of heavy oils
During the past 20 years, the oil industry has begun to transition away from light oils toward heavier oils. But transporting heavy oils cost-effectively is a challenge because heavy oils are viscous -- essentially a thick, sticky and semifluid mess. One way to outmaneuver this problem, reported in Physics of Fluids, is a viscoplastic lubrication technique. It can complement existing methods to stabilize interfaces within multilayer flows. (2019-10-08)

Robot control system for grasping and releasing objects under both dry and wet conditions
A control system for deformable robot-fingertips was developed for grasping and releasing objects. Previously developed robot fingertips with high friction texture can stably grasp a paper box, a soft object under both dry and wet conditions. By injecting a lubricant (absolute ethanol) the grasped object slipped downwards without changing the position of the robot fingertips. The current controlling system using lubricant could be applied to robot tasks in a narrow space. (2019-07-16)
