•    The effect of calcination time was studied on the properties of TiO2/ZnO composite.
•    Increasing calcination time can increase agglomeration of TiO2/ZnO particles.  
•    By increasing calcination time, antibacterial activities of TiO2/ZnO decreases.

Highlights
    Nd doping enhances the frequency-dependent dielectric properties of 1-y) Bi1-xNdxFeO3-yPbTiO3 solid solutions with x = 0.05 to 0.20 at intervals of 0.05 and y = 0.1 to 0.4.
    Dielectric anomalies were more noticeable around the transition temperature, which suggests stronger magnetoelectric interactions.
    As Nd content increases, temperature-dependent dielectric permittivity predicts relaxor-type ferroelectric performance for y = 0.4 composition of solid solutions.
    With increased Nd doping, all P-E loops exhibit a pinning effect that may be connected to the samples' ability to store energy.
    Nd doping effectively reduces leakage current by about four orders of magnitude. It significantly broadens its applicability in devices requiring stable, efficient, and low-power electrical performance
 

Highlights:

•    The reduction in interlamellar spacing of Fe3C within the pearlite phase enhances the tensile properties of SUP9 steel
•    SUP9 steel is suitable for leaf spring component due to its high yield-to-ultimate strength ratio, which indicates excellent plastic deformation capability
•    Cracks propagate faster in the longitudinal-transverse (LT) orientation than in the transverse-longitudinal (TL) orientation
•    The role of non-metallic inclusions, such as MnS precipitates and spherical oxides, in facilitating crack growth
