It is here that shape becomes relevant, because, for ellipsoidal particles, surface tension can be turned against itself. First, it causes the particles to become strongly attached to the air ...

Scientists have developed the most accurate model yet of how the coronavirus particles rotate, according to their ellipsoidal shape. Since the start of the COVID-19 pandemic, images of the ...

"The shape of the particles really seems to matter because the stretched, ellipsoidal particles we made performed much better than spherical ones in activating the immune system and reducing the ...

Ever wonder why a drop of coffee leaves a ring behind when it dries? Physicists did. In 1997, they came up with a theory of how it works. It turned out to be such a universal theory that it shows ...

Microscope images of infected tissues have revealed that coronavirus particles are actually ellipsoidal, displaying a wide variety of squashed and elongated shapes. Now, a global research team, ...

Spherical and ellipsoidal carbon nanomaterials are referred to as fullerenes, while cylindrical ones are called nanotubes. These particles have many potential applications, including improved films ...

In a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their ...
