Disulfide

The researchers wondered if they could figure out how to capture that electrical charge as it moved across the membrane separating the fresh and salty water. They did it by creating two tiny membranes, just three atoms thick, made of molybdenum disulfide, which is plentiful and easy to produce. Then they made a tiny hole in the membranes and let osmosis take over and push the electrically charged salt ions through this nanopore.

By analysing data from the James Webb Space Telescope, the researchers found evidence of dimethyl sulfide and dimethyl disulfide in the atmosphere of the planet known as K2-18b. The planet is 124 light-years away; one light-year is equivalent to nearly 6 trillion miles.
