“…Piezoelectrics are a noncentrosymmetric crystal structure that separates positive and negative charges under the action of external forces, resulting in a corresponding piezopotential [116][117][118]. Piezocatalysis refers to the conversion of mechanical energy into chemical energy.…”

Advanced oxidation technology of persulfate is a new method to degrade wastewater. As the economy progresses and technology develops, increasingly more pollutants produced by the paper industry, printing and dyeing, and the chemical industry are discharged into water, causing irreversible damage to water. Methods and research directions of activation persulfate for wastewater degradation by a variety of iron-based catalysts are reviewed. This review describes the merits and demerits of advanced oxidation techniques for activated persulfate by iron-based catalysts. In order to promote the development of related research work, the problems existing in the current application are analyzed.

“…[16][17][18][19][20][21][22] Despite the wide range of applications, exible and wearable pressure sensors still have several challenges, which revolve around achieving quick response, high sensitivity, excellent operational stability, ultralow detection limits, and robustness. 23,24 To address these challenges, many researchers have demonstrated a variety of exible pressure sensors based on piezoresistive, [25][26][27] capacitive, [28][29][30][31][32] piezoelectric, [33][34][35] and triboelectric 14,[36][37][38] mechanisms, presenting high mechanical exibility and superior key parameters (such as sensitivity, response/recovery time, working stability, and detection limit). They have also explored the applications of these sensors in exible electronics, wearable devices, electronic skin, and human-machine interface devices.…”

This work describes the development and characterization of tetragonal barium titanate nanoparticles (BTO NPs) and their surface functionalization with dopamine dodecylamine (DDA), a lipophilic organic ligand. The so‐obtained lipophilic NPs (BTO‐DDA) are then formulated at low loadings (< 5 wt.%) into liquid photocurable resins for vat photopolymerization (VP) and 3D printed into solid objects. The printed composites are mechanically characterized in order to assess the effect of the nanomaterial on the mechanical properties of the 3D printed polymer, revealing no significant variations in the mechanical properties (tensile or flexural) of the nanocomposites compared to the original polymer matrix. In light of these results, the printed nanocomposites are studied in terms of their capacity to generate a separation of charge by the piezoelectric effect, typical of the BTO crystal structure. This study reveals that BTO‐loaded nanocomposites display outstanding piezoelectric coefficients as high as 50 pC/N when BTO‐DDA is formulated at 3.0 wt.%, only slightly less than one‐third of the piezoelectric coefficient previously reported for bulk BTO, while preserving the mechanical properties of the polymer matrix.
