Barium titanate-based energy-storage dielectric ceramics have attracted great attention due to their environmental friendliness and outstanding ferroelectric properties. Here, we demonstrate that a recoverable energy density of 2.51 J cm-3 giant efficiency 86.89% can be simultaneously achieved in 0.92BaTiO3-0.08K0.73Bi0.09NbO3 ceramics. In addition, excellent thermal stability (25-100 °C) superior frequency (1-100 Hz) been obtained under 180 kV cm-1. The first-order reversal curve method...
We report ultrahigh dielectric and piezoelectric properties in BaTiO3-xBaSnO3 ceramics at its quasi-quadruple point, a point where four phases (Cubic-Tetragonal-Orthorhombic- Rhombohedral) nearly coexist together the temperature-composition phase diagram. At this permittivity reaches ∼75000, 6–7-fold increase compared with that of pure BaTiO3 Curie point; coefficient d33 697 pC/N, 5 times higher than BaTiO3. Also, system exhibits double morphotropic boundaries, which can be used to reduce...
Monodispersed ferroelectric BaTiO3 nanoparticles are synthesized as a model system to investigate the effect of ferroelectricity on photocatalytic process.

Mechanical flexibility of electronic devices has attracted much attention from research due to the great demand in practical applications and rich commercial value. Integration functional oxide materials flexible polymer proven an effective way achieve devices. However, chemical mechanical incompatibilities at interfaces dissimilar make it still a big challenge synthesize high-quality single-crystalline thin film directly on substrates. This study reports improved method that is employed...
Contemporary models of intrafibrillar mineralization mechanisms are established using collagen fibrils as templates without considering the contribution from collagen-bound apatite nucleation inhibitors. However, matrices destined for in vertebrates contain bound matrix proteins mineralization. Negatively charged, high-molecular weight polycarboxylic acid is cross-linked to reconstituted create a model examining collagen-ligand interaction Cryogenic electron microscopy and molecular dynamics...
Doping with heteroatoms is being used as an effective way to change electronic structure of electrode materials for advanced storage systems.

Nanocomposites incorporating inorganic nanoparticles (NPs) within ferroelectric polymeric matrices have great potential for high density energy capacitors. In this strategy, employing the nanostructures with specially designed morphology as fillers would notably improve storage. However, strategy is extremely challenging and has not been largely explored.
