TL;DR: The Wombat powder diffractometer as discussed by the authors was designed for experiments requiring rapid real-time acquisition (time-resolved environmental or kinetics experiments) or very good signal to noise (experiments with difficult sample environments or small sample volumes).

TL;DR: In this paper, the phase stability and energy storage properties of La-doped AgNbO3 lead-free ceramics were investigated, and the temperature and electric field-dependent dielectric constants showed that the antiferroelectric phase stability is enhanced via the La doping.

TL;DR: The structural response to electrochemical cycling of the components within a commercial Li-ion battery (LiCoO2 cathode, graphite anode) was shown through in situ neutron diffraction as mentioned in this paper.

TL;DR: In this paper, the authors reported direct measurements of non-180° domain wall motion in ceramic lead zirconate titanate during application of sub-coercive cyclic driving electric fields using an in situ stroboscopic neutron diffraction technique.

TL;DR: In this article, high-resolution neutron diffraction has been used to investigate the structural origin of the large electric-field-induced remanent strain in 94(Bi1/2Na 1/2)TiO3-6BaTiO 3 ceramics, and the virgin material was found to be a mixture of near-cubic phases with slight tetragonal and rhombohedral distortions of a 0a0c+ and a−a −a−a− octahedral tilt type.
