New type of atomic clock keeps time even more precisely
Furthermore, one cesium atom will oscillate at exactly the same frequency as another cesium atom. To keep perfect time, clocks would ideally track the oscillations of a single atom. But at that scale, an atom is so small that it behaves according to the mysterious rules of quantum mechanics: When measured, it behaves like a flipped coin …Web

Process for recovering cesium from cesium alum
Cesium is recovered from cesium alum, CsAl(SO4)2, by a two-reaction sequence in which the cesium alum is first dissolved in an aqueous hydroxide solution to form cesium alum hydroxide, CsAl(OH)3, and potassium sulfate, K2SO4. Part of the K2SO4 precipitates and is separated from the supernatant solution. In the second reaction, a water-soluble …Web

The entropy and Gibbs free energy of formation of the aluminum ion
The potential for disorder in the cesium alum struc- ture cannot be overlooked (PAULING, 1935 and CROMER et al. 1966). Any disorder would increase the entropy of cesium alum, which would lead to a less negative value for the entropy of the aluminum ion derived from the Table 1.
