Application

  • Cesium-containing triple cation perovskite solar cells: improved stability, reproducibility and high efficiency: Demonstrates how adding cesium to perovskite solar cells improves their stability and efficiency, making a significant advancement in solar technology (M Saliba et al., 2016).
  • Exotic stable cesium polynitrides at high pressure: Explores the formation of new cesium polynitrides under high pressure, indicating potential applications in high-energy-density materials (F Peng et al., 2015).

General description

Cesium(Cs) is a highly reactive alkali metal known for its unique properties its uniqueproperties, such as a low melting point and high atomic mass, which enhance itsexceptional conductivity and reactivity. Its compounds, particularly cesiumlead halide perovskites, are extensively utilized in next-generation solarcells to achieve high efficiency and stability. Additionally, cesium isutilized in electron emission devices and photonic technologies.

A novel biosorbent derived from agricultural residue - walnut shell (WS) is reported to remove cesium from aqueous solution. Nickel hexacyanoferrate (NiHCF) was incorporated into this biosorbent, serving as a high selectivity trap agent for cesium. Field emission scanning electron

The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry, rooted in the atomic shell structure. Within compounds, Group I elements, for example, invariably assume the +1 oxidation state, and their chemical

A noncentrosymmetric chiral Strandberg-type polyoxometalate based material, Cs(4)Mo(5)P(2)O(22), that contains unusual one dimensional chains constructed from [Mo(5)P(2)O(23)](6-) units has been reported. Cs(4)Mo(5)P(2)O(22) shows a moderate SHG response, and is phase-matchable.
