DOI: 10.1007/s10854-017-7052-x
Abstract: Monophasic K0.5Gd0.5Bi4Ti4O15 powders were synthesized via a citrate-based sol–gel route. Rietveld analysis of powder X-ray diffraction data confirmed the composition to be a pure four-layer Aurivillius phase with an orthorhombic structure (space group A21am and… read more here.

DOI: 10.1016/j.ceramint.2020.04.122
Abstract: Abstract The structural stability of the multiferroic four-layer Aurivillius ceramic Bi5FeTi3O15 (BFTO) under hydrostatic pressure was investigated in situ by synchrotron X-ray powder diffraction (SXRPD) and Raman spectroscopy. Measurements performed up to 15 GPa allowed the… read more here.

DOI: 10.1039/d2cc05742e
Abstract: We synthesized planar chiral cyclophanes with multiple pairs of helical conformations that were generated by twisting at the interlayer. Three- and four-layer cyclophanes preferred a homochiral form with a single sense of twisting through intramolecular… read more here.
