Relaxor ferroelectrics (RFEs) are being actively investigated for energy-storage applications due to their large electric-field-induced polarization with slim hysteresis and fast energy charging-discharging capability. Here, a novel nanograin engineering approach based upon high kinetic deposition is reported, mechanically inducing the RFE behavior in normal ferroelectric Pb(Zr0.52 Ti0.48 )O3 (PZT), which results simultaneous enhancement dielectric breakdown strength (EDBS ) polarization....
Summary The pump-in/flowback test (PIFT), often referred to as the diagnostic fracture injection (DFIT) with flowback, offers notable advantages in terms of time efficiency and accuracy, particularly context low-permeability formations. key success this lies careful selection an optimal flowback rate yield meaningful results. fundamental assumption underlying pressure analysis these tests is uniform closure fractures during phase, which considered default mode current analyses. In study, we...
High Energy Density Capacitors In article number 2302554, Long-Qing Chen, Shashank Priya, Dae-Yong Jeong, Jungho Ryu, and co-workers reveal a giant energy storage density of over 120 J cm−3 with an ultrahigh breakdown strength 540 MV m−1 (equivalent to the ferroelectric polymers) in nanograin engineered PZT thick film. The nano-grain architecture composite microstructure crystalline amorphous phase same composition, achieved through mechanical tailoring, exhibits artificial relaxor behavior,...
