Future of inks, paints and coatings takes shape: Researchers determine that particle shape affects the 'coffee ring effect'
First, a little fluid dynamics: As the liquid in a droplet evaporates the edges remain fixed, so as the volume decreases fluid flows outward from the middle of the droplet to its edges ... ring effect. Both the shape that liquid droplets take, and the ...
Science: What Does It Matter
The three states ... matter, noting that the molecules are held tightly together with fixed volume and hold their shape. Volume was introduced by pouring colored water into different shaped containers, noting the liquid takes the shape of its container.
Physicists find patterns in new state of matter
(PhysOrg.com) -- Physicists at the University of California, San Diego have discovered patterns which underlie the properties of a new state of matter. In a paper published ... “We are working both on understanding the basic properties of excitons ...
Disordered Hyperuniformity: A Weird New State of Matter in Chicken Eyes
Having particles packed closely together but with no ordered structure, unlike amorphous solids, liquids will flow freely and not hold a shape (on their own). This state of matter has a constant volume ... will take the shape of its container, but unlike ...
Why does Matter take up Space?
Big deal, I can’t put two identical fermions in the same quantum state ... there’s a finite volume that — once it’s occupied by one of these matter particles — it’s off-limits to the others! And that’s why matter takes up space, no matter ...
