It looks interesting, but the article has too few details. Some more info in the first reference https://pmc.ncbi.nlm.nih.gov/articles/PMC11936013/ Anyway, IIUC it discuss a research lab method, that may be hard to escale to factory production.
I’ve just been swallowed by a rabbit hole on heavy hydrogen, the Norwegian hydro plant used to make fertiliser by splitting water and D being left behind, then them realising they could sell D₂O.
It being used in some medicines, and in semiconductor processes, then in preserving Blue OLED for longer.
Most heavy water for reactors was made by the Girdler sulfide process. This is what Canada used for CANDU reactors. Since then, they developed a better technology using catalytic exchange columns allowing equilibrium of hydrogen isotopes between hydrogen gas and water. By passing water down such a column counterflowed against hydrogen coming back up, the deuterium is stripped into the downflowing water. If the water is then electrolyzed to make the hydrogen then it becomes enriched in deuterium, with the hydrogen leaving the column depleted.
If Canada ever sells many more CANDU reactors they'll use this sort of technology to make their moderator.
I recall someone found that treating silicon chips with deuterium reduced the rate of electromigration in narrow channels, extending chip life.
