For decades, atomic clocks have been the pinnacle of precision timekeeping, enabling GPS navigation, cutting-edge physics research, and tests of fundamental theories. But researchers are now pushing ...

A solid-state nuclear clock has a great potential to become a robust and portable timing device that is highly precise.

Thorium, an abundant and safer alternative to uranium, could soon become a vital resource in the quest to meet energy needs.

A thorium-doped calcium fluoride crystal's temperature is continually monitored while a VUV frequency comb is used to directly resolve individual quantum states of the nuclear transition.

China has found a treasure that will change its fortunes. Chinese geologists have discovered huge thorium reserves in the country. This reserve is so huge that it can end China's electricity problems ...

China has announced the discovery of vast thorium reserves, a radioactive metal being hailed as a potential " limitless " ...

There could be no doubt about the position of elements like radium,-”thorium, and uranium which could be obtained in large enough quantities to determine their atomic weights and chemical ...

As the nuclear reactor “burns” U-235, the concentration of U-235 decreases while radioactive by-products such as fissile plutonium increase. Eventually, the nuclear chain reaction can no longer be ...
