Construction of NaNbO3/CdS nanorods composites with pyroelectric effect for enhanced pyrocatalytic and antibacterial activity under room-temperature cold-hot cycles

Pyroelectric effects in CdS phase junctions for dual-enhanced photocatalytic hydrogen production

“…12,15 A similar phenomenon can be seen within other wurtzite materials such as CdSe, 16 ZnS, 17,18 and GaN. 19 For CdS, the combination of CdS with other different semiconductors has been studied to enhance the pyroelectric properties of materials such as NaNbO 3 /CdS, 20 SnS/CdS, 13 and BaTiO 3 /CdS. 21 In addition, Zhang et al 22 found that CdS nanorods decorated with an organic molecule, 2-mercaptobenzimidazole (2MBI), can greatly enhance the pyroelectric properties and pyroelectric-induced charge separation.…”

External physical field‐driven nanocatalytic cancer therapy

“…thermoelectric effect to sustain the reaction to generate ROS. Because of the specificity of the thermoelectric effect, it has been gradually used in recent years in fields such as H 2 production, [105] dye decomposition, [106] sterilization, [107,108] and disease treatment. [109] No matter which mechanism of thermo-catalytic therapy, the heat source is the primary prerequisite.…”

“…In addition, periodic temperature changes are often required to continuously trigger the thermoelectric effect to sustain the reaction to generate ROS. Because of the specificity of the thermoelectric effect, it has been gradually used in recent years in fields such as H 2 production, [105] dye decomposition, [106] sterilization, [107,108] and disease treatment [109] …”

In Situ Polymerization of Methylene Blue on Bacterial Cellulose for Photodynamic/Photoelectricity Synergistic Inhibition of Bacterial Biofilm Formation

“…26,28 In comparison, inducing the discharge of electrical signals from materials with less intense stimulation techniques has become a viable alternative for antibacterial impact. 29 Under illumination at specific wavelengths, electrons within the material absorb energy and escape to form a current, which can be observed to have a stable photocurrent density and is considered a potential candidate for antibacterial applications. 27,30 Furthermore, electrical stimulation can perturb the bacterial growth environment by hindering the growth of bacterial biofilms.…”

“…Indirect effects are achieved by electrically inducing autolysis or stimulating the production of toxic substances that disrupt the cell structure, effectively inhibiting bacteria and biofilms . Compared to continuous electrical stimulation, generating electrical signals through stimulating materials can achieve more ideal antibacterial effects through on-demand antibacterial activity. , However, direct stimulation through external power sources may not only be unsuitable for daily use but also cause safety issues. , In comparison, inducing the discharge of electrical signals from materials with less intense stimulation techniques has become a viable alternative for antibacterial impact . Under illumination at specific wavelengths, electrons within the material absorb energy and escape to form a current, which can be observed to have a stable photocurrent density and is considered a potential candidate for antibacterial applications. , Furthermore, electrical stimulation can perturb the bacterial growth environment by hindering the growth of bacterial biofilms .…”
