That's a little too convenient to not be engineered. That being said, it's likely that their research had already undergone some degree of progress, and their announcement was a fluffed up reflection of that to score a point against the US. So I'm not discarding anything completely here, but it's kind of impossible to tell to what degree it's true or not, as is typical w/ China. So, as per usual, I'll believe it when it exists in a functioning product. Reply
chaos215bar2 So, do we have a published paper explaining exactly how the cooling process using this new alloy works, or just a news article from a Chinese source specifically calling out DARPA? The big problem that comes to mind is, how does this alloy dissipate heat without dumping some of it into the object intended to be cooled? With a standard helium cryostat, this is simple enough and not fundamentally that different from the standard refrigeration cycle. (Well, it's pretty different, but the helium carries the heat away, just like any refrigerant would.) Can this alloy selectively dump its heat in one direction? Or was the test just a one off, capable of briefly reaching the desired temperatures but not necessarily maintaining them over any period of time? Reply

Here is the article published in Nature: https://www.nature.com/articles/s41586-026-10144-zThe news source is kinda bad for not linking the actual published paper, but it's real research and actually legitimately in one of the most prestigious scientific journals globally.

Too bad there doesn't seem to be a plain PDF copy available anywhere. I guess it's a little harder to complain since the research was funded within China, but still, the idea of paying $30+ simply to access a single scientific paper is so counter to the kind of open communication scientific progress thrives on, it's almost insulting.

TheOtherOne They could probably go even lower, if they added Copium into the mix! 😉 Reply

I mean its Nature's policy, take it up with them. If you really want a PDF copy, often you can just ask the authors directly and many are willing to freely provide a copy. I imagine they just didn't bother putting it on free hosting websites since they are China based. Reply
