I notice they mentioned application of this to polar shipping, but NOT to reducing icing on aircraft wings, e.g., which seems to me, a non-expert on all things, to be a far more important technological application. Hmm... perplexing. But interesting anyway.
Can you think of other possibly important applications for this "discovery"?
This could be used to prevent icing on power lines so they do not get weighed down.
THAT’S a good one, thanks!
Brought to you and me, and all of us, by the lowly mussel.
There have been several attempts at making ice-free surfaces for various applications such as aviation. Many of them involve using engineered nanostructured surfaces.
The problem with nanostructured surfaces, or even larger, microscopic surface features is that they wear off very quickly. Kind of like Rain-X on you windshield. It lasts for a while but gradually small bits of dust blast the coating away.
I have a project at work which involves freezing a solution. We wanted to use metal molds but have found ice sticks to all metals and even Teflon. Can’t use nanostructured surfaces because the molds would wear out too quickly.
Seriously, thank you.
The article doesn’t make any sense. Anything will freeze whenever it’s temperature goes below it’s own freezing point. It doesn’t matter what the condition of its surrounding material is. It could be solid, liquid, or gas. The article seems to indicate that the mussels’ surface can shed ice particles easily, but it doesn’t explain at why it doesn’t itself freeze.

Mighty fine eatin’.
I love scallops.
Could you use a thin metal mold, then briefly heat it enough that the ice comes loose enough to be taken out?
My understanding... It freezes, but it doesn’t adhere. It flakes off easily.
Yes that can be done, as it is for popsicles. However we have found a blast freezer can freeze so quickly that silicone molds work fine. The trick is the air must flow quickly to remove heat rapidly.
Yum, I want some! I LOVE seafood. Wife hates it. She accommodates me. I accommodate her. So we never eat it, LOL.
These mussels are stressed and not thinking Warm
I’m hungry.

Puget Sound Mussels, having filtered through the secondary sewage treatments release into the Sound. Chop away.
There is so much sewage in the Sound that underwater looks like floating bits of TP, but are really algae blooms on even smaller bits of s...t paper. Salmon are forced into the upper water columns and become easy prey for Seals and Sealions
That sounds like a lot of bull scat.
Suspect the sound is a lot cleaner than it was 40-50 years ago when sewer pipes went straight out.

Nope - Sea/Tac only does secondary treatment - you must have tertiary to produce clean water (a very expensive process - one which few cities do). Secondary releases lots of particulate matter, which produces blooms in warm weather. Just ask any one who uses nets to fish about algae blooms and the origins.
Nonsense.
