The core of the story has to be technology focused.


Post guidelines

Title formatPost title should mirror the news source title. If you don't like the title of article, look for an alternative source instead of editorializing it.
URL formatPost URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
[Opinion] prefixOpinion (op-ed) articles must use [Opinion] prefix before the title. Opinion articles refer to articles that their publisher doesn't explictly endorse.
Country prefixCountry prefix can be added to the title with a separator (|, :, etc.) if the news is from a local publisher who doesn't clearly mention the country.


Rules

1. English onlyTitle and associated content has to be in English.
2. Use original linkPost URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
3. Respectful communicationAll communication has to be respectful of differing opinions, viewpoints, and experiences.
4. InclusivityEveryone is welcome here regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
5. Ad hominem attacksAny kind of personal attacks are expressly forbidden. If you can't argue your position without attacking a person's character, you already lost the argument.
6. Off-topic tangentsStay on topic. Keep it relevant.
7. Instance rules may applyIf something is not covered by community rules, but are against lemmy.zip instance rules, they will be enforced.

"Canot be explained."

...then the scientists explain it.

*sigh

The first layer is the familiar Cr2O3 based passive film. Then, at around ~720 mV, a manganese based layer forms on top of the chromium based layer. This second shield helps protect the steel in chloride containing environments up to an ultra high potential of 1700 mV.

That is what makes the finding so striking. Manganese is usually not viewed as a friend of stainless steel corrosion resistance. In fact, the prevailing view has been that manganese weakens it.

"Initially, we did not believe it because the prevailing view is that Mn impairs the corrosion resistance of stainless steel. Mn-based passivation is a counter-intuitive discovery, which cannot be explained by current knowledge in corrosion science. However, when numerous atomic-level results were presented, we were convinced. Beyond being surprised, we cannot wait to exploit the mechanism," said Dr. Kaiping Yu, the first author of the article, whose PhD is supervised by Professor Huang.

They know how to make it work. The currently unexplainable part is why because manganese is the key to this working. Manganese usually doesn’t protect stainless steel from corrosion but it is when layered over the chromium based layer.

Drs. Hate that one simple trick you did

[–] Cursed_Fig@lemmy.world 6 points 6 days ago

Man they can explain HOW it works but not WHY it works that way, contrary to the old understanding.

Did you sleep through all your English classes?

a genie came and conjured up this material and it can't be explained. wait no. we made it and know everything about making it.

Clickbait is now just straight up lying

Lying with pure hubris rather than having a slight bit of subtly to it, mr/ms calculator
