irradiating them with ultrasonic waves.

Ultrasound is not a form of radiation. It is sound waves, nothing more. Glaring mistakes in basic science like this throw doubt on the veracity of the rest of the article.

I think you jumped the gun with your criticism there.

Ultrasonic Irradiation is a technique for chemical synthesis, used especially in organic chemistry. It’s a relatively new technique so older folks such as us may not have read about it during our days of studying organic chemistry.

Ban the chemicals for a start

Yep, we don't need them.

I'm actually quite happy with my cast iron skillets.

That was my first reaction too but it seems that I am also too old to understand.

At one end of the molecule, there is a group of charged oxygen atoms which can be targeted using a common solvent and reagent at mild temperatures of 80-120 degrees Celsius, decapitating the head group and leaving behind a reactive tail. "Once that happens, that provides access to previously unrecognized pathways that cause the entire molecule to fall apart in a cascade of complex reactions," said Dichtel, ultimately making benign end products.

Sounds like something from a horror or sci-fi film.

The current study focused on 10 PFAS chemicals including a major pollutant called GenX, which for example has contaminated the Cape Fear River in North Carolina, a water source for 350,000 people.

I have a friend from North Carolina and he is a little strange, now I know why.

Thanks for the heads up, EvilBuddha.

Now I'm not sure which is more scary, PFAS or Ultrasonic Irradiation.

One very important thing to get home from the report is that there is value in checking things, even if they would seem as terribly obvious and it would be tempting to think they have been tried before by someone else. As in this case it may not be the case and you can make a huge contribution about the useful properties of things as common as DMSO and sodium hydroxide.
