Summary
A Chinese research team at the Chinese Academy of Sciences in Qingdao has developed a material called PhosCage, which they claim can extract uranium from seawater more efficiently than previously thought possible. The researchers achieved an extraction rate 8 times higher than the US target rate, capturing 22.55mg per gram of uranium over seven cycles of reuse. This breakthrough uses a sponge-like molecular structure that acts as a chemical trap to capture the nuclear fuel. The team believes this novel approach could lay the groundwork for large-scale uranium recovery from seawater.

Story summary
A Chinese research team, affiliated with the *Chinese Academy of Sciences* in *Qingdao*, has developed a material called PhosCage that can extract uranium from seawater at an impressive rate. The team claims their method opens up a new approach to recovering nuclear fuel from oceans worldwide. Using millimeter-sized beads** made from PhosCage, they were able to capture *22.55mg of uranium per gram* and maintain this effectiveness through seven cycles of reuse. This achievement exceeds the target extraction rate set by the US, which is at a much slower pace. The success of PhosCage has potential for large-scale use in the future.

Why this leaning score
This article does not take a side on a contested political
question, so it has no leaning score. That is an
answer rather than a gap: a match report or a rescue can be warmly
or critically written without being left or right, and scoring it
anyway is how approval of a subject gets recorded as a political
position.

Researchers developed a material that they say opens up a ‘novel approach’ to recover the nuclear fuel from the world’s oceans
The team from the Chinese Academy of Sciences in Qingdao did this using a material they developed called PhosCage – a sponge-like molecular structure filled with phosphate groups that act as chemical traps.

They then turned PhosCage into millimetre-sized beads that are easier to deploy and retrieve in the open ocean.

“This work opens up a novel approach to extracting uranium from seawater and lays the groundwork for adsorbents that can capture more uranium and eventually be used on a large scale,” the team from the CAS’ Qingdao Institute of Bioenergy and Bioprocess Technology said in the statement.
