Integration of Bi4O5I2 nanoparticles with ZnO: Impressive visible-light-induced systems for elimination of aqueous contaminants

Retracted: A concise review on the elastomeric behavior of electroactive polymer materials

“…Unluckily, most of the films that were synthesized were too brittle and had low molecular weight, which made them unsuitable for use in DEA membranes 216 . The product with suitable characteristics was realized through the reorganization reaction of the polar group up to 3.4% in the elastomeric backbone 217 . This sample exhibited an actuation strain of 6.2% (almost six times of the starting material), lower Young's modulus, and high dielectric permittivity ( ε = 2.4 to ε = 3.0) compared to neat silicone at electric field of 37.5 V/μm (Figure 11).…”

“…Like a functionalize elastomeric chain of high molecular weight polymethyl‐vinyl‐siloxane, used by Dünki et al where for the incorporation of extremely polarizing units, nitrile functional group from 3‐mercaptopropionitrile vinyl groups were applied as an initiating point 218 . The authors introduced these functional groups not only to enhance the permittivity but also to a cross‐link site to adjust the final mechanical properties of the elastomer matrix with various catalysts 5, 10, 12, 98–219 . This material showed ε = 10.1 at 104 Hz with 154 kPa value of elastic modulus, thus made possible the electromechanical performance of 20.5% at electric field of 10.8 V/μm (low value).…”

“…These filers are also temperature‐dependent, thus would reduce the dielectric actuators elastic DAE application limit. The problems were partly solved by the coating of BT particles with a thin layer of polydopamine, 5, 10–12, 115–246 which improves its dielectric permittivity and reduces dielectric loss.…”

“…However, no data were presented on the material dielectric breakdown. Romasanta et al reported the improvement in the dielectric permittivity of an elastomeric matrix by using graphene layers 5, 10, 12, 108–229 . The author co‐related the dielectric permittivity of MWCNT/PDMS composites and functionalized graphene sheets ( FGS /PDMS) at 25°C.…”

A review of graphene‐TiO2 and graphene‐ZnO nanocomposite photocatalysts for wastewater treatment

“…Therefore, newer techniques are needed to be developed which can efficiently remove rigid pollutants like dyes, metal ions, several chemical compounds, and so forth (Bethi et al, 2017) Currently, photocatalysis has attracted the most attention for wastewater remediation activities (Ge et al, 2019;Pedanekar et al, 2020). Different types of materials have been envisaged to serve as photocatalysts (Kumar et al, 2020(Kumar et al, , 2021Madani et al, 2021;Meshram et al, 2017). The well-known photocatalysts such as zinc oxide (ZnO) and titanium dioxide (TiO 2 ) are used for removal or degradation of pollutants from wastewater because of their impressive oxidizing potential, costeffectiveness, chemical inertness, non-toxicity, and stability towards photocatalysis (Bhanvase et al, 2014).…”
