A five-phase equilibrium. Image: ICMS animation studio Five different phases of a colloid-polymer mixture can co-exist at the same time, in defiance of the 150-year-old Gibbs phase rule, which states ...

The phase diagram between lead and tin shows the eutectic invariant reaction between these two constituents. At the eutectic temperature of 183 C, three phases exist in equilibrium: (Pb) with the ...

Two-phase equilibrium: A binary colloidal mixture can exist in up to six phases at the same time. (Courtesy: R Tuiner) A binary colloidal mixture can exist in up to six phases at the same time, ...

Today, researchers are defying a classical theory from American physicist Josiah Willard Gibbs, with proof of a five-phase equilibrium, something that many scholars considered impossible.
