New Material Can Soak Up Uranium From Seawater (acs.org)
A new adsorbent material "soaks up uranium from seawater, leaving interfering ions behind," reports the ACS's Chemical & Engineering News, in an article shared by webofslime:
The world's oceans contain some 4 billion metric tons of dissolved uranium. That's roughly 1,000 times as much as all known terrestrial sources combined, and enough to fuel the global nuclear power industry for centuries. But the oceans are so vast, and uranium's concentration in seawater is so low -- roughly 3 ppb -- that extracting it remains a formidable challenge... Researchers have been looking for ways to extract uranium from seawater for more than 50 years...
Nearly 20 years ago, the Japan Atomic Energy Agency (JAEA) confirmed that amidoxime-functionalized polymers could soak up uranium reliably even under harsh marine conditions. But that type of adsorbent has not been implemented on a large scale because it has a higher affinity for vanadium than uranium. Separating the two ions raises production costs. Alexander S. Ivanov of Oak Ridge National Laboratory, together with colleagues there and at Lawrence Berkeley National Laboratory and other institutions, may have come up with a solution. Using computational methods, the team identified a highly selective triazine chelator known as H2BHT that resembles iron-sequestering compounds found in bacteria and fungi.... H2BHT exhibits little attraction for vanadium but has roughly the same affinity for uranyl ions as amidoxime-based adsorbents do.

I disagree. Trump is safely contained within the White House where he can be safely monitored by VPOTUS Pence.
Let's take a look into the Oval Office and see how that's going...
Pence: Mr. President I think you did very well today but we do need to discuss your tweets. You think you can scale back the volume of tweets you send out in any given day?
Trump: Of course. I'll get right on that, Mike.
P: Are you tweeting right now?
T: Maaaaaaybeeeee.
P: You think you could perhaps stop until, I don't know, breakfast tomorrow? We can talk about it more then.
T: Yeah. Yeah, sure sure.
P: I'll see you at breakfast in the Green Room then? As usual?
T: Sounds great, Mike. I'll see you in the morning, goodnight. Oh, and how does something from Denny's sound?
Yep, nothing wrong here. Safely contained.
