A distillation tray is used to mix vapors and liquids together. The better the mixing, the more efficiently the tray works. Tray efficiency also depends on two other factors: how well the droplets of ...

Ionic liquids are useful substances, but in certain applications their utility is limited because they are involatile — or so we thought. In fact, some ionic liquids can be distilled, and even ...

For centuries, distillation has been used to separate the components of liquid solutions through extremely selective heating and cooling. Numerous instruments are used to control the differing ...

Listen to the full series on BBC Sounds. Fractional distillation works because the different liquids have different boiling points. When the mixture is heated: vapours rise through a column which is ...

While it holds promise, membrane distillation doesn't work perfectly. A key challenge is designing membranes to purify water efficiently while ensuring zero contamination of the clean water. In new ...

Scientists have developed 'porous liquids': Nanoparticles, that are able to separate gas molecules of different sizes from each other, float - finely distributed - in a solvent. The porous liquids may ...

Dec. 10 --Natural compounds added to marijuana-derived vaping liquid produce toxic chemicals in the vapor that users inhale, a new lab study reports. The compounds, known as terpenes, are added into ...

Jointly with cooperation partners, a researcher of Karlsruhe Institute of Technology (KIT) has developed "porous liquids": Nanoparticles, that are able to separate gas molecules of different sizes ...
