The technology, enabled by thorium atoms, could keep time more accurately than atomic clocks and enable new discoveries about ...

China's Chang'e-6 mission brought back unique lunar samples from the moon's far side. These samples show distinct characteristics with lower density and different mineral content compared to previous ...

The low-energy excited state of thorium-229 (229Th) isotope nucleus has recently gained much attention owing to it being an ideal candidate for ultra-precise nuclear clocks. Building such ...

For this nuclear clock, the scientists used ultraviolet light to excite nuclear particles in an atom of thorium-229 embedded in solid crystal. They then measured the frequency of the energy pulse ...

The first nuclear clock based on thorium-229 shows unprecedented precision and may test if fundamental constants change.

China plans to build the world's first-ever nuclear power station using molten salt as the fuel carrier and coolant, and ...

For some 15 years, I have followed the re-emergence of nuclear Thorium or ‘the green nuclear’ as it is often referred to. Way back, an experimental Thorium Molten Salt Reactor was built at Oak Ridge ...

China is planning to build the world's first-ever nuclear power station using molten salt as the fuel carrier and coolant, and thorium as a fuel source. Experts say the reactors are "inherently ...

A study led by graduate student Chuankun Zhang at the University of Colorado showed that it is possible to compare the transition between energy states in thorium-229 with a strontium-based atomic ...

So, researchers focused their attention on thorium-229 since its nucleus needs a smaller energy jump than any other known atom, requiring ultraviolet light, which has lower energy than X-rays.

That’s why the newly described clock runs on thorium, whose nucleus only requires ultraviolet light to make energy jumps. “With this first prototype, we have proven: Thorium can be used as a ...
