F4, the latest cesium fountain clock that now stands as one of the most accurate timekeepers in the entire world.

When the microwave signal exactly matches the material’s resonance frequency — 9.192631770 GHz, in the case of cesium — the number of atoms changing state will be at a maximum, so you know ...

Cesium is a metal in group IA of the periodic table with atomic number 55, an atomic weight of 132.905, and a density of 1.9 Mg/m 3. Its melting point is 28.7 C, and it boils at 690 C. The electronic ...

Maybe that’s even more than half of the fun. [CuriousMarc] got an HP 5061A Cesium clock, a somewhat famous instrument as the model that attempted to prove the theory of relativity. The reason?

Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) have identified a way for plants to gain resistance to cesium, a radioactive toxin that can be found in contaminated soil.

Results are highly encouraging as cesium is a high-value commodity due to its rarity and specialized applications. Darren L. Smith, Patriot Executive and Vice President of Exploration, comments ...

Once the capsule is opened, more than 250 people end up contaminated by the substance called Cesium 137, being the biggest radiological accident in the history of Brazil.

[Photo/Agencies] China said on Monday that it found no abnormality in the activity concentration of hazardous elements such as tritium, cesium-134, cesium-137 and strontium-90 in seawater and ...

This photograph is an example of DNA separated in a cesium chloride density gradient. Two tubes containing cesium chloride gradients are arranged vertically next to each other. The gradients have ...
