The mechanical stability of these compounds was confirmed by Born stability criteria. The optical behavior was assessed using different parameters, including the optical conductivity(σ), the absorption coefficient(α), the reflectivity(R), and the loss parameter(L). Furthermore, the thermal properties were explored utilizing the electrical conductivity (σ/τ), charge carrier concentrations (n), Seebeck coefficient (s), specific heat capacity (C_v), magnetic susceptibility (χ), thermal conductivity (K_e/t) and power factor (PF) parameters. These values were calculated with the help of the BoltzTraP program combined with the WIEN2k, utilizing the PBE-GGA approximation in density functional theory.

We present a new Zn₃(OH)₂V₂O₇·2H₂O/Betalains nanocomposites (ZVH@Bn NCs) utilizing natural betalain pigment for green energy devices such as LIBs and supercapacitors for the first time.

They improve electrical conductivity by facilitating faster charge transfer and lowering the band gap of the NCs.
