Piezoelectric and optical setup to measure an electrical field: Application to the longitudinal near-field generated by a tapered coax [PDF]
, 2008 We propose a new setup to measure an electrical field in one direction. This setup is made of a piezoelectric sintered lead zinconate titanate film and an optical interferometric probe.

Nuclear-spin relaxation of $^{207}$Pb in ferroelectric powders
, 2007 Motivated by a recent proposal by O. P. Sushkov and co-workers to search for a P,T-violating Schiff moment of the $^{207}$Pb nucleus in a ferroelectric solid, we have carried out a high-field nuclear magnetic resonance study of the longitudinal and ...

Thermodynamics of mono and di-vacancies in barium titanate [PDF]
, 2012 The thermodynamic and kinetic properties of mono and di-vacancy defects in cubic (para-electric) barium titanate are studied by means of density-functional theory calculations. It is determined which vacancy types prevail for given thermodynamic boundary

Constructing Ionic Fast Diffusion Channels on LiNi0.5Mn1.5O4 for Lithium‐Ion Batteries
Advanced Functional Materials, EarlyView.A dual‐modification strategy is developed for LNMO cathode, where bulk Ti doping stabilizes the oxygen framework and simultaneously drives the in situ formation of LaTi2O6 nano‐islands as ion diffusion channels on (111) surfaces, enabling high‐rate capacity (∼100 mAh g−1 at 30 C) and excellent cycling retention (87.8% after 1000 cycles).
