Fish, seaweed inspire slippery surfaces for ships

Long-distance cargo ships lose a significant amount of energy due to fluid friction. Looking to the drag reduction mechanisms employed by aquatic life can provide inspiration on how to improve efficiency.

Don't shuffle on slippery surfaces, researchers say

Biomechanics researchers Timothy Higham of Clemson University and Andrew Clark of the College of Charleston conclude that moving quickly in a forward, firm-footed stance across a slippery surface is less likely to lead to ...

A novel salvinia-like slippery surface

Superhydrophobic surfaces are widely used in many industrial settings, which mainly consist of rough solid protrusions that entrap air to minimize the liquid/solid area. The stability of the superhydrophobic state favors ...

Dual-action 'slippery' catheter fights bacteria

A super-slippery coating being developed at a University of Wisconsin–Madison lab could benefit medical catheters, factory equipment, and even someday, oil tankers.

Collecting tiny droplets for biomedical analysis and beyond

In a single sneeze or a cough, as many as 40,000 tiny droplets are forcibly propelled from the mouth and nose into the air. Researchers from City University of Hong Kong (CityU) have recently developed a method to collect ...
