Investigation of negative resistance regions in W-WO3 nanoparticles and UV-B light detection properties of PVA-W-WO3 flexible composite films

Controlled Growth of a Highly Energetic, Less Electron-Dense Tetrahedral Fe3+ Phase on the Surface of α-Fe2O3 Nanoparticles toward Enhanced Optical, Magnetic, and Supercapacitive Performance

“…So, shielding effects reduce the reaction kinetics of the A 4 sample in SO 3 2– electrolytes. But the overall enhancement of conductivity and loosely interacted covalent bond of composite films play a dominant role in boosting C P values effectively by 12% for EG-supported PEDOT:PSS polymer-based hematite nanoparticles. − …”

Tunable, reversible resistive switching behavior of PVA-zirconia nanocomposite films and validation of the trap-assisted switching mechanism by the selective application of external bias voltages

“…22 This indicates two different zirconia (ZO) nanoparticle phases that have nearly the same growth rates at the time of synthesis. 22 [23][24][25] The inclusion of ZO nanoparticles (0.5 vol% to 4 vol%) in the PVA matrix significantly reduced the crystallite size (from 4.5 nm to 4 nm for PZ0.5 and PZ4 films, respectively) and altered the growth mechanism of the composite's film. To completely comprehend the crystal growth kinetics of blends, we examined the XRD peaks at 19.71 for all the composite films in Fig.…”

“…The intercepting point represents the bandgap wavelengths, and the associated bandgap has been calculated from the relation E g (eV) = 1242.375/l (nm). 25,45 Fig. S3 (ESI †) displays the enhancement of crystallinity and the abundance of loose H-bonds that reduces the optical bandgap from 5.48 eV to 5.12 eV for PZ0.5 and PZ4 films, respectively.…”
