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.

Right, global warming causes snow in Arizona. Tell me something, what kind of weather or climate event would there have to be to disprove the theory of human caused global warming from burning fossil fuels?
A year-on-year decrease in global temperatures, obviously.
The climate changes, and I can't seem to find anyone to dispute that. If you want me to believe your theory then first I need to see the theory explained in a way that is falsifiable.
If you still find greenhouse gases confusing, there's really no explaining the situation to you.
I know what is holding up synthetic fuels. It is the Democrat "Green New Deal" that denies us access to nuclear power.
That's a seriously stupid thing to say on multiple levels, and this is my surprised face. First level, nuclear power is unprofitable, it would make more sense to get the power from renewables. Second level, nuclear power was unprofitable and unpopular before the "Green New Deal" was proposed, but you're blaming it anyway. That's because you're a troll.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
