Effect of amaranth on dielectric, thermal and optical properties of KDP single crystal

Hydrogen Bonding Paradigm in the Formation of Crystalline KH2PO4 from Aqueous Solution

“…Potassium dihydrogen phosphate (KH 2 PO 4 , KDP) is a well-known hydrogen bonded crystal, which possesses special ferroelectrics, nonlinear optical, and electro-optic properties. , KDP crystallizes in tetragonal structure, where each tetrahedral H 2 PO 4 – is hydrogen bonded to the other four H 2 PO 4 – . Previous studies show that phosphate has selectivity and high affinity as metal receptors or selectively binds organic molecules; − therefore, the phosphates can affect biological and ecological systems significantly. , For example, it has been reported that the phosphate ions and water molecules can be used to tune the metastability of amorphous calcium carbonates in organisms . Both experimental observations and theoretical calculations have been carried out to investigate the clusters such as hydrated ions and atomic groups and the interactions in H 2 PO 4 – –H 2 O and H 2 PO 4 – –H 2 PO 4 – . − By combining the infrared multiple photon dissociation (IRMPD) spectra with ab initio molecular dynamics (AIMD), it has been described the anharmonic and dynamic effect on the structure and size of H 2 PO 4 – (H 2 O) n clusters and the formation of hydrogen bond network around a H 2 PO 4 – through solute–solvent .…”
