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 ...
(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. ...
(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 ...
Microdroplets find versatile applications in fields of chemistry, materials science and biochemistry, particularly in chemical engineering and biochemical microfluidics like microreactors and biosensors. Achieving precise ...
