Bulky molecules mimic some properties of PFAS without their long-lasting chemical bonds and could replace PFAS in some water-repelling applications.

The first is surface tension — a cohesive force at the surface ... exhibited liquid-like properties and formed a single quantum droplet. This droplet was then placed in a laser-created path ...

The initial shape relaxation dynamics observed as oscillations in droplet shape can be used to infer the surface tension of aerosol droplets. A comparison of the surface tension of Triton X-100 ...

But as we increased the tilt, gravity pulled the red blood cells downhill, while surface tension tried to hold ... up unevenly on either side of the droplet—a difference that helps explain ...
