Although several past studies have investigated the formation of crystals from identical particles, the conditions under which non-uniform particles crystallize and the crystals resulting from this process are still poorly ...
(Phys.org)—In a normal rainbow, red is always on "top" while violet is on the "bottom." This is true whether the rainbow is created by a glass prism or by water droplets in the sky, and is due to the way that these materials ...

A team of researchers from Pomona College and the Rancho Santa Ana Botanic Garden has figured out how a wild petunia plant is able to fling its seeds so far. In their paper published in the Journal of the Royal Society Interface, ...
(Phys.org)—HD 47366 is an evolved star almost twice as massive as our sun. Located about 260 light years from the Earth, the star is approximately 1.6 billion years old, and, as it turns out, hosts two giant planets with ...

A dispersant or a dispersing agent or a plasticizer or a superplasticizer is either a non-surface active polymer or a surface-active substance added to a suspension, usually a colloid, to improve the separation of particles and to prevent settling or clumping. Dispersants consist normally of one or more surfactants, but may also be gases.
