Imprinting oxides Dislocations can be problematic for the properties of functional oxides and are often avoided as a result. Höfling et al. found that introducing a network of dislocations to barium titanate actually enhanced the dielectric and piez

Mimicking the scheme of incorporating La3+ to Pb(Zr1−xTix)O3, Ca2+ is used to substitute Na+ in the lead-free NaNbO3 compound, with A-site vacancy introduced to maintain charge neutrality. The anticipated relaxor behavior is expected to suppress th

Antiferroelectric ceramics are exploited for applications in high energy-density capacitors due to their reversible electric-field-induced phase transitions. The difference in the fields between the forward and reverse transition is termed electric h

Pt-based alloys are currently one of the most popular choices for high-performance ORR catalysts in PEMFCs. However, they often require multi-step synthesis or cumbersome intermediate treatment processes and high-temperature annealing steps. Herein,

Antiferroelectrics (AFEs) have a great potential for modern electronic devices by virtue of the large strain during the antiferroelectric-to-ferroelectric (AFE-FE) phase transition under external electric fields. Although the fascinating macroscopic
