Abstract The increasing demand for a whiter smile has resulted in an increased popularity tooth whitening procedures. most classic hydrogen peroxide-based agents are effective, but can lead to enamel demineralization, gingival irritation, or cytotoxicity. Furthermore, these techniques excessively time-consuming. Here, we report nondestructive, harmless and convenient strategy based on piezo-catalysis effect realized by replacement of abrasives traditionally used toothpaste with piezoelectric...

High piezoelectric and ferroelectric properties have been found in Mn-doped Na0.5Bi0.5TiO3–BaTiO3 single crystals, which were grown by a top-seeded solution method. The electrical resistivity, dielectric constant, all to be notably enhanced Mn. constant d33 electromechanical coupling coefficients kt k31 as high 483 pC/N, 0.56, 0.40, respectively. These values are much higher than those previously reported for Pb-free demonstrating the real potential alternative lead-free systems sensor applications.
A giant magnetoelectric (ME) effect in self-biased annealed Metglas/Pb(Zr,Ti)O3/Metglas laminates under zero magnetic bias is reported. The remanent magnetization was increased by annealing Metglas, which generated an internal field. This shifted the M-H hysteresis loops, yielding large values for ME voltage coefficient of αME = 12 V/cm·Oe and 380 at 1 kHz electromechanical resonance bias, respectively. laminate shown to have a high sensitivity ac fields.
Abstract Since industry‐standard piezoelectric materials, such as lead zirconium titanate ceramics, contain toxic lead, a rapid surge in research on lead‐free materials is occurring due to concerns over environmental safety and human health.

Perovskite ceramics and single crystals are commonly hard brittle due to their small maximum elastic strain. Here, large-scale BaTi0.95 Co0.05 O3 (BTCO) film with a SrRuO3 (SRO) buffered layer on 10 µm thick mica substrate is flexible bending radius of 1.4 mm semitransparent for visible light at wavelengths 500-800 nm.

Oxide ferroelectric ceramics and single crystals for flexible wearable device applications significantly suffer from the nature of hardness brittleness due to their small maximum elastic strain technological challenge in thinning micrometer or nanometer scale. Although many oxide films are thin enough be flexible, rigid substrates restrain piezoelectric d 33 coefficient limit performance. Here, large‐scale PbZr 0.52 Ti 0.48 O 3 (PZT) with SrRuO (SRO) buffered layer grown on 10 µm thick mica...
Abstract Tooth whitening has recently become one of the most popular aesthetic dentistry procedures. Beyond classic hydrogen peroxide-based agents, photo-catalysts and piezo-catalysts have been demonstrated for non-destructive on-demand tooth whitening. However, their usage challenged due to relatively limited physical stimuli light irradiation ultrasonic mechanical vibration. To address this challenge, we report here a convenient strategy based on pyro-catalysis effect, realized via...

Lead-free antiferroelectric ceramics have drawn widespread interest recently on account of their environmentally friendly components and potential applications in high-power systems. However, relatively low recoverable energy storage density (Wrec < 10 J/cm3), limited by the electric breakdown strength (Eb 60 kV/mm), efficiency (η 80%), generated large hysteresis during antiferroelectric–ferroelectric phase transition, seriously restricted application portable compact electronic devices. In...
