Biomimetic adsorbent efficiently extracts uranium from seawater

The oceans hold an enormous amount of very diluted uranium that could potentially serve as a sustainable fuel source for nuclear power. But how can uranium be extracted quickly and efficiently from seawater?

Balancing high selectivity for ions with rapid transport of those ions has long been a major challenge in obtaining uranium from the sea. Now a groundbreaking study suggests a solution.

A research team led by Prof. Wen Liping from the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences has developed a biomimetic adsorbent that can attract and hold uranium ions. The inspiration for this adsorbent is the natural porous structure of the spiky, globular fruit of the Chinese sweetgum tree, Liquidambar formosana. The team’s findings were recently published in Matter.

Scientists Just Built a Battery That Never Needs Charging

Imagine never charging your phone again or having a pacemaker that lasts a lifetime. Scientists are developing tiny nuclear batteries powered by radiocarbon, a safe and abundant by-product of nuclear plants.

Unlike lithium-ion batteries, which degrade over time and harm the environment, these new designs use beta radiation to trigger an electron avalanche and generate electricity. The team’s latest prototype vastly improved efficiency, and though challenges remain, the technology could one day make nuclear power as accessible as your pocket device.

US-built fusion reactor structure delivered for 60-ft-tall ITER magnet

Fusion is inching closer to reality with continuous development in this field as the United States Domestic Agency for the International Thermonuclear Experimental Reactor (ITER) recently completed the delivery of critical components for the support structure of central solenoid.

Described as an exoskeleton, or a cage, the support structure surrounds the central solenoid, which is a 60-foot-tall superconducting magnet at the heart of the ITER fusion machine.

US firms plan nuclear-powered spacecraft for deep space exploration

The goal of enabling extended deep-space exploration is driving NASA, space agencies, and private players to explore nuclear power solutions.

Recently, two Southern California-based startups, Exlabs and Antares Nuclear, announced a partnership to advance deep-space missions with nuclear-powered spacecraft.

SpaceNews reported that the Exlabs’ Science Exploration and Resource Vehicle (SERV) spacecraft will be equipped with Antares microreactors.

Producing nuclear fusion fuel is banned in the US for being too toxic: Researchers find an alternative

Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, usually requires liquid mercury, which is extremely toxic. Now, researchers have developed a mercury-free method to isolate lithium-6 that is as effective as the conventional method. The new method is presented in the journal Chem.

“This is a step towards addressing a major roadblock to nuclear energy,” says chemist and senior author Sarbajit Banerjee of ETH Zürich and Texas A&M University. “Lithium-6 is a critical material for the renaissance of nuclear energy, and this method could represent a viable approach to isotope separation.”

The conventional method used to isolate lithium-6, called the COLEX process, involves liquid mercury and has been banned in the United States since 1963 due to pollution concerns.
