Descrizione generale

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.

Applicazioni

  • 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).

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.

QX-314 (N-ethyl-lidocaine) is a cationic lidocaine derivative that blocks voltage-dependent sodium channels when applied internally to axons or neuronal cell bodies. Coapplication of external QX-314 with the transient receptor potential vanilloid 1 protein (TRPV1) agonist capsaicin produces long-lasting sodium channel
