"Canot be explained."
...then the scientists explain it.

What doesn't fit here?
The core of the story has to be technology focused.
- If article mentions "AI" in a sentence and then talks about business economics that doesn't make it tech news.
- Gaming is too many layers removed from technology. There are many dedicated communities that are a better fit for it.
- Transporation is too many layers removed from technology. EVs while use many cool technologies have many dedicated communities that are a better fit for it.
- Entertainment is too many layers removed from technology. While sometimes it can fit here, business or cultural aspects of it are a better fit for dedicated communities.
- Cybersecurity. While it heavily focuses on technology, most of the time it's too technical for most people who are not already invested in it. Should be posted in a dedicated communities unless it has broader connection to other tech areas.
Post guidelines
Title format
Post 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 format
Post 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] prefix
Opinion (op-ed) articles must use [Opinion] prefix before the title. Opinion articles refer to articles that their publisher doesn't explictly endorse.
Country prefix
Country 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 only
Title and associated content has to be in English.
2. Use original link
Post 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 communication
All communication has to be respectful of differing opinions, viewpoints, and experiences.
4. Inclusivity
Everyone 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 attacks
Any 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 tangents
Stay on topic. Keep it relevant.
7. Instance rules may apply
If something is not covered by community rules, but are against lemmy.zip instance rules, they will be enforced.

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.

Industrial Engineers slammed by ultra stainless steel. "I was speechless", says factory worker.
Was it "unprecedented"?
That's One of the Top Ten Most Things That It Was. Number Seven Will Shock You.
Drs. Hate that one simple trick you did
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
Always has been
Lying with pure hubris rather than having a slight bit of subtly to it, mr/ms calculator
"inexplicable": a higher manganese content causes a secondary passive layer to form at approximately 720 mV
