Abstract:
Rare-earth-based materials are pivotal in optical applications, particularly as nonlinear optical (NLO) materials, owing to their exceptional structural tunability and functional properties. In this study, a novel fluoride, AgCe3F13, was synthesized via a facile hydrothermal method combined with a cation substitution strategy, wherein Ag+ ions replaced NH4+ ions in the parent compound NH4Ce3F13. To further tailor the crystal structure, Li+ ions were introduced, yielding a new noncentrosymmetric hydrated fluoride, LiAgCe2F10(H2O)2. Structural analysis reveals that AgCe3F13 comprises interconnected [Ce3F22]10- clusters and [Ag2F9]7- dimers, while LiAgCe2F10(H2O)2 features unique {[LiAgF5(H2O)2]3-}∞ chains and {[Ce2F10]2-}∞ pseudolayered motifs. Notably, LiAgCe2F10(H2O)2 exhibits a phase-matchable second-harmonic generation (SHG) response with an efficiency of approximately 0.6 times that of KH2PO4 (KDP). This work demonstrates the efficacy of cation modulation as a versatile strategy for the design of advanced functional optical materials.

Ligand Binding and Linkage
Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...
