Two types of heterogeneous mixtures are suspensions and colloids. Suspensions are made of the largest particles and can be easily separated by physical means such as filtering. A colloid’s particle ...

While an antimatter engine is very far off, researching it could yield other discoveries as well.

The entire sample is subjected to a well-defined magnetic force, so variations are limited to the properties of the suspension (particles, buffer). Its precise separation parameters ensure a ...
