Hollow, pumpkin-shaped molecules can efficiently separate valuable hydrocarbons from crude oil, KAUST researchers have shown.

There are different ways to separate mixtures, eg by filtration, crystallisation, distillation or chromatography. The method chosen depends upon the type of mixture.

The most striking result was taking a 50/50 mixture of lanthanum and dysprosium and getting back 99.7% dysprosium in one step--a "100% boost" compared to the same method but without using a magnet.

Purifying mixtures without using heat would lower global energy use, emissions and pollution — and open up new routes to resources, say David S. Sholl and Ryan P. Lively.

What happens to the color of the mixture? Do you see separate layers forming? Now, add one teaspoon of salt to the mixture in cup 3. Put the lid on the cup and shake it for 20 to 30 seconds.

Researchers at Pennsylvania University found a way to separate mixtures of rare earth metals by combining a magnetic field with a decrease in temperature, a process that causes metal ions to ...
