(Phys.org) —When a rubber ball and a droplet of water are compressed onto a solid surface, they behave very differently. For the ball, the compression process is reversible, so the ball retains its original form when decompressed. ...
Sometimes water spreads evenly when it hits a surface; sometimes it beads into tiny droplets. While people have noticed these differences since ancient times, a better understanding of these properties, and new ways of controlling ...

(Phys.org)—Researchers from the University of Michigan working in collaboration with associates from the US Air Force have created a new type of surface cover that repels oils, water, alkali solutions, acids and even non-Newtonian ...
When peanuts are dropped into a pint of beer, they initially sink to the bottom before floating up and "dancing" in the glass.

Researchers have gained valuable insights into the behaviour of water on strongly hydrophobic (water-repelling) surfaces. Understanding this behaviour should help scientists develop new types of surfaces with applications ...

(PhysOrg.com) -- Extremely hydrophobic materials cause water to roll right off objects that have been coated with them. Up to now, it was assumed that aircraft or wind turbines coated in such a way did not ice up as easily. ...

An international research team, led by Monash University, has discovered for the first time the mystery behind the formation of 'coffee rings' by examining the contact angle of droplets onto a surface, and how they dry.

In materials science, surfaces that strongly repel low surface tension liquids are classified 'superoleophobic," while high surface tension liquid repellants are 'superhydrophobic' and surfaces that display both characteristics ...
Rice University scientists who invented laser-induced graphene (LIG) for applications like supercapacitors have now figured out a way to make the spongy graphene either superhydrophobic or superhydrophilic.
