Ultra-sensitive flexible piezoelectric energy harvesters inspired by pine branches for detection

A rationally designed 3DTiO2@CdZnS heterojunction photocatalyst for effectively enhanced visible-light-driven hydrogen evolution

“…Synthesis of three-dimensional TiO 2 . Three-dimensional TiO 2 (3DTiO 2 ) was prepared as follows: 40 firstly, 1.5 ml of tetrabutyl titanate was mixed well with the prepared solution containing 30 ml of deionized water and 30 ml of hydrochloric acid. Then 0.1 g of 1DTiO 2 was added to the mixed solution and stirred magnetically for 30 min.…”

“…[34][35][36][37] There are also a lot of reports on two-dimensional TiO 2 nanomaterials, 38,39 but 3D TiO 2 and its composites with complex morphologies are almost rarely reported. 40 Inspired by the above, firstly, the unique morphology of a 3D nanorod structure of TiO 2 was prepared by combining electrospinning and hydrothermal methods. Then, the 3DTiO 2 /CZS photocatalyst was successfully prepared for the first time by an in situ hydrothermal growth method.…”

All‐organic shell–core PVDF/PMMA composite fiber films with enhanced piezoelectric performance for flexible sensing and energy harvesting

“…[7][8][9][10] Therefore, the study on the structure of PVDF and PVDF matrix composites has become an important direction of piezoelectric composites in the future. Among the known common piezoelectric polymers, PVDF exhibits the strongest piezoelectric effect, 11,12 and researchers have conducted in-depth studies on PVDF-based piezoelectric composites. [13][14][15][16][17][18] PVDF typically exists in three crystalline forms: α phase, β phase, and γ phase.…”

Enhanced energy storage capabilities in PbHfO3-based antiferroelectric ceramics through delayed phase switching and induced multiphase transitions

“…However, their energy density remains relatively low. [4][5][6][7][8][9] To realize device miniaturization and improve overall performance, it becomes essential to further augment the recoverable energy density (W rec ) of ceramic capacitors.…”
