Thorium is a relatively abundant, slightly radioactive element which is commonly produced as a byproduct of mining rare-earth metals. On its own, thorium isn't fissile, which means it doesn't ...

Research has been published over the past few decades on the possible use of thorium in various nuclear power reactor types. Therefore, it is worthwhile to analyse the supply situation for additional ...

Camera lenses? A few decades ago, camera companies added rare elements like thorium to their glass to change the optical properties in desirable ways. The downside? Well, it made the lenses ...

For decades, atomic clocks have been the pinnacle of precision timekeeping, enabling GPS navigation, cutting-edge physics research, and tests of ...

This clock could revolutionize timekeeping by using a uniquely low-energy transition within the nucleus of a thorium-229 atom ... physics beyond the Standard Model. This idea isn't new in Ye's ...
