• The solid polymer electrolyte films for Pure PVB and 70PVB+30NaNO₃+wt%Fe₂O₃ were prepared using a solution casting technique.
• XRD, FTIR, and SEM are used for amorphousness, complex formation, and surface morphology studies of polymer electrolytes.
• PVB+NaNO₃+Fe₂O₃ (70:30:3%) film exhibits the highest conductivity (2.51×10⁻⁵ S cm^-1).
• Wagner’s polarization technique, can be employed to measure the ionic and electronic transport numbers of all prepared samples.
• The Open Circuit Voltage (OCV) of 2.0V and a Short Circuit Current (SCC) of 0.8 mA were found in the discharge characteristics data for the cell constructed with the polymer electrolyte sample.

 

HIGHLIGHTS:
1 - The hyperbolic sine model provided the most accurate fit for hot compression flow data.
2 - Activation energy for deformation was calculated as 293.37 KJ/mol using Arrhenius equations.
3 - Recrystallization fraction increased with temperature and decreased with strain rate.
4 - Grain sizes at 950, 1050, and 1150 ℃ were measured as 17.7 µm, 28.7 µm, and 31.3 µm.
5 - More uniform grain size distribution was observed with increasing deformation temperature.
6 - The Avrami exponent was measured around 2, indicating nucleation at grain boundaries.


 

Both when the p-n junction is under the influence of strong microwave field and without the influence of strong microwave field, the differential resistance increases with the increase in the value of the coefficient of non-ideality of the p-n-junction I-V characteristics.
Both when the p-n junction is under the influence of strong microwave field and without the influence of strong microwave field, the diffusion capacity decreases as the value of the non-ideality coefficient of the p-n junction I-V characteristics increases.
