This was an activity to simulate Mars explorers' efforts to find basic signs of life, but it will also serve to further our understanding of basic terraforming capabilities. Through the use of a centrifuge in the lab, we separated out the samples. In the coming weeks, we will use a ...
Epoxy compounds are a very important class of organic chemical raw materials and intermediates. This type of compound molecule contains a three-membered oxygen ring structure. Under the action of an acidic or alkaline catalyst, the three-membered oxygen ring is easily ring-opened and can be ...

the technique to separate the components of milk and cream. In 1875, Prandtl's brother, Alexender, refined the technique, inventing a machine to extract butterfat. While centrifuges are still used to separate milk components, their use has expanded to many other areas of science and medicine....
