A team of chemists and engineers in China has developed a new, efficient way to separate oil and water mixtures. In their paper published in the journal Science, the group describes how they developed ...

they produce the same number of spots, and these match in colour the spots travel the same distance as they have the same R f value R f values can be used to identify unknown chemicals if they can ...

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

Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size. In gel electrophoresis, the molecules to be separated are pushed by an ...

Separating mixtures into their constituent substances is essential in many fields. For example, mixture separation plays a key role in the petrochemical industry, as well as in chemical ...

Mixtures of oil and water can be efficiently separated by pumping them into thin channels between semipermeable membranes, ...

Trying to separate pumpkin seeds from slimy pulp can be unpleasant and frustrating, but you can use kitchen tools you already ...

How do complex mixtures of chemicals affect our health? New research has shown that chemicals that occur in complex mixtures and in concentration ratios as found in humans act together.

Named after the two-faced Roman god Janus to reflect its dual-purpose design, researchers present a novel membrane system – a Janus channel of membranes (JCM) – capable of simultaneously separating ...

They enter our bodies through food, air or the skin. But how do these complex mixtures of chemicals affect our health? In a new study, a research team from the Helmholtz Centre for Environmental ...

Reshmi Bennett: ‘The best way to use a hand mixer is to always start ‘low and slow.’ Introduce ingredients gradually, ...

The bad news: The chemicals acted together to make the entire mixture toxic. “Though they are structurally similar, not all forever chemicals are made equal — some are more potent, others less. When ...
