Abstract:
... Flux synthesis is an effective method to discover large crystals of new compounds. In this paper, a solid-state reaction in Li flux produced a new nitridolithosilicate La₄Ba₃Li₃Si₉N₁₉ in the orthorhombic space group Cmcm (No. 63) with lattice parameters of a = 9.7263(1), b = 18.2746(2), c = 11.2929(1) Å, and Z = 4. The La₄Ba₃Li₃Si₉N₁₉ exhibits a 3-D framework based on triangular clusters (3-rings) ...

Abstract:
... Although smectite-type clays are used as heterogeneous media for photofunctional guest molecules, the guest species are limited to cationic or polar molecules because of the intrinsic negative electric charges of clay particles. Nevertheless, in this study, aqueous clay colloids are reported to affect the photoisomerization kinetics of anionic and cationic azobenzene molecules dissolved in the col ...
