You’ve heard of turning water into wine, however how about turning whisky into water… kind of.
Scientists on the University of Manchester have demonstrated the capabilities of graphene-oxide membranes – by producing clear whisky.
Previously, the membranes have been proven to be utterly impermeable to all solvents aside from water, however a badysis group on the National Graphene Institute and School of Chemical Engineering and Analytical Science have tailor-made the membrane to permit all solvents to cross by means of.
The ultra-thin membrane can nonetheless be used to sieve out the smallest of particles, reminiscent of numerous natural dyes as small as a nanometre dissolved in methanol.
Professor Rahul Nair, who’s main the badysis group, mentioned: “Just for enjoyable, we even filtered whisky and cognac by means of the graphene-oxide membrane. The membrane allowed the alcohol to cross by means of however eliminated bigger molecules, which supplies the amber color.
“The clear whisky smells much like the unique whisky however we’re not allowed to drink it within the lab, nonetheless it was a humorous Friday night time experiment.”
This new and environment friendly separation course of minimises the consumption of vitality, which is in excessive demand – based on Professor Nair by 2030 the world will devour round 60 per cent extra vitality than it does as we speak.
Dr Yang Su, who led the experiment, added: “The developed membranes will not be solely helpful for filtering alcohol, however the exact sieve dimension and excessive flux open up new alternatives to separate molecules from totally different natural solvents for chemical and pharmaceutical industries.
“This development is particularly important because most of the existing polymer-based membranes are unstable in organic solvents, whereas the developed graphene-oxide membrane is highly stable.”
The membranes have attracted an excessive amount of consideration for his or her means to filter salty water and make it drinkable, a possible resolution to water shortage and drought.
Graphene is stronger than metal, versatile, bendable and a million instances thinner than a human hair.
