Quick-Drying, Fast-Cracking

Water droplets filled with nanoparticles leave behind deposits as they evaporate. Like a coffee ring, particles in the evaporating droplet tend to gather at the drop’s edge (left). As the water evaporates, the deposit grows inward (center) and cracks start to form radially. After just a couple minutes, the solid deposit covers the entire area of the original droplet and is shot through with cracks (right).

Researchers found that the cracks’ patterns and propagation are predictable through a model that balances the local elastic energy and and the energy cost of fracture. They also found that the spacing between radial cracks depends on the deposit’s local thickness. Besides explaining the patterns seen here, these cracking models could help analyze old paintings, where cracks could hide information about the artist’s methods and the artwork’s condition.

Via #RawStory, 7:20am EDT, OCT 24

#CNN has obtained a video deposition of #Trump ally #MikeFlynn acknowledging that he has no evidence to back up a key part of the #Conspiracy theories he's floated for years about the #2020election being rigged against the former president.

The #deposition was taken as part of a #defamation lawsuit filed by former #DominionVotingSystems executive #EricCoomer, who was falsely accused of stealing the election from Trump four years ago

"#TheApprentice": the #film #ConvictedFelon #DonaldTrump doesn't want you to see

A new #movie about #young #DonaldTrump hits #theaters Friday, despite Trump trying to block its release. It paints an #unflattering #portrait of his #rise as a #realestate #mogul — and Republicans are calling it #election #interference.

The scenes are based on #IvanaTrump's #divorce #deposition in 1990, in which she detailed a 1989 #sexualassault.
