Rules:

1. Be civil

Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.

Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.

3. No bots, spam or self-promotion.

Only approved bots, which follow the guidelines for bots set by the instance, are allowed.

4. Post titles should be the same as the article used as source.

Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.

5. Only recent news is allowed.

Posts must be news from the most recent 30 days.

6. All posts must be news articles.

No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.

7. No duplicate posts.

If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.

8. Misinformation is prohibited.

Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.

9. No link shorteners.

The auto mod will contact you if a link shortener is detected, please delete your post if they are right.

10. Don't copy entire article in your post body

For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

anyone with a better understanding able to articulate potential trade-offs/complications to using this in practical applications?

the critical field and critical current seem very low … This means you can't actually push big current through this thing (yet). You can't make a powerful magnet, and you can't make viable power lines

The method to produce this material as described in the related paper [1] is fairly simple and could be done at home with a $200 home metal melting furnace from amazon and the precursors (which also seem to be fairly standard easy to obtain metals)

Read this comment thread from SC researchers: <reddit link removed>
Lots of problems with the paper, they claim. It is not up to the standards of current SC research. One of them says Dias's work shows more merit than this.

It would be a real bummer if this came out to be untrue. However it's simple enough to replicate, so we will know soon enough
