Over more than three decades, the scientific community has been contentiously interested in
structuring varying photocatalytic materials with unique properties for appropriate …

The processing of genuine and high-performance Bi-based aurivillius perovskites with their
layered morphology is an emerging topic in coordination chemistry. The inorganic bulk …

The description of displacive distorted structures in terms of symmetry-adapted modes is
reviewed. A specific parameterization of the symmetry-mode decomposition of these …

Fabricating complex transition metal oxides with a tunable bandgap without compromising
their intriguing physical properties is a longstanding challenge. Here we examine the …

The use of bismuth-layered perovskite films for planar-type nonvolatile ferroelectric random-
access memories requires films with spontaneous polarization normal to the plane of …

The recent rerefinements of the crystal structures of Bi 4 Ti 3 O 12, Bi 3 TiNbO 9, and Bi 2
WO 6 differ substantially from earlier reported structure refinements. A comparison of the …

The effects of concentration and distribution of defects controlled by quenching and doping
of higher-valent cations on the ferroelectric properties of dense Bi 4 Ti 3 O 12 ceramics were …

According to the EU-Directives 2002/95/EC, 2002/96/EC, lead-based piezoceramics must
be substituted in the future with more environmentally friendly alternatives, only when a …

Many Aurivillius phases of ferroelectric complex bismuth oxides are currently known. With
the formula Bi 2 A m− 1 B m O 3m+ 3, they all consist of Bi 2 O 2 layers interleaved with …
