Domain structure and phase evolution in quenched and furnace cooled lead-free Na1/2Bi1/2TiO3–BaTiO3 ceramics

, 2021
Relaxor ferroelectric Na1/2Bi1/2TiO3-based materials have gained considerable attention as a potential lead-free alternative in recent years and can be tailored to exhibit giant strain or superior high power properties.

Factors Influencing Nerinetide Effect on Clinical Outcome in Patients Without Alteplase Treatment in the ESCAPE-NA1 Trial

Journal of Stroke
Background and Purpose In the ESCAPE-NA1 (Efficacy and Safety of Nerinetide for the Treatment of Acute Ischaemic Stroke) trial, treatment with nerinetide was associated with improved outcomes in patients who did not receive intravenous alteplase.

Correlation between enhanced lattice distortion and volume fraction of polar nanoregions in quenched Na1/2Bi1/2TiO3–BaTiO3 ceramics

, 2021
Quenching has been established as a viable method to increase the depolarization temperature in (100-x) Na1/2Bi1/2TiO3–xBaTiO3 (NBT–xBT). The proposed hypothesis of a stabilized ferroelectric order would entail changes in the polarized volume.
