Morphogenesis mechanisms in the hydrothermal growth of lead-free BCZT nanostructured multipods

Abstract

Due to growing environmental concerns on the toxicity of lead-based piezoelectrics, the replacement of Pb-based materials by the homologs with comparable piezoelectric properties but without lead is an emergent task....

The paradigm of the filler's dielectric permittivity and aspect ratio in high-k polymer nanocomposites for energy storage applications

“…Ba 0.85 Ca 0.15 Zr 0.10 Ti 0.90 O 3 near-spherical particles (B_NP), H 2 (Zr 0.1 Ti 0.9 ) 3 O 7 nanowires (HZTO_NW) and Ba 0.85 Ca 0.15 Zr 0.10 -Ti 0.90 O 3 rod-like (B_NR) nanopowders were synthesised using soft-chemistry routes. 45,[57][58][59] The elaborated nanofillers were shown to have different morphologies and/or permittivities (see Table 1 and Fig. 1).…”

The benefits of combining 1D and 3D nanofillers in a piezocomposite nanogenerator for biomechanical energy harvesting

“…The detailed structural, morphological and piezoelectric characterisation can be found in the literature. 30,36 2.2. Preparation of BCZT multipods BCZT multipods were prepared via the hydrothermal reaction of HZTO-nw with barium acetate and calcium nitrate tetrahydrate, as reported in ref.…”

A flexible self-poled piezocomposite nanogenerator based on H2(Zr0.1Ti0.9)3O7 nanowires and polylactic acid biopolymer

“…[48][49][50] In particular, Zr-doped HTO nanowires (H 2 (Zr y Ti 1−y ) 3 O 7 , HZTO) are used to fabricate 1D-perovskite oxides with fascinated ferroelectric and piezoelectric properties similar to the state of the art PbZr y Ti 1−y O 3 (PZT) and Ba 1−x Ca x Zr y Ti 1−y O 3 (BCZT). [51][52][53][54] Nevertheless, to the best of our knowledge, the piezoelectric properties and the mechanical energy harvesting capability of HZTO nanowires have not yet been investigated.…”
