TL;DR: In this article, the effect of BaTiO3 substitution on the dielectric, ferroelectric and magnetic properties of the BiFeO3 multiferroic perovskite was studied.

Abstract: BiFe 1− x Cr x O 3 ( x = 0, 004, 006 and 008) nanoceramics were prepared by sol–gel method Nanoceramics were calcined at 450 °C Calcined powders were leached in diluted nitric acid to get single phase TEM analysis shows the particle size to be ∼80 nm Thermogravimetric analysis of as prepared powder indicates that the single phase is formed at around 450 °C Magnetization was found to increase as the concentration of Cr was increased Dielectric constant and dielectric loss were found to decrease with increase in frequency for all the compositions Magnetocapacitance was found to increase with magnetic field For BiFe 1− x Cr x O 3 ( x = 004, 006 and 008) nanoceramics, the change of dielectric constant induced by magnetic field may be well approximated by Δ ɛ / ɛ = γ M 2 , here, γ (magnetoelectric interaction) is small and positive A linear fit gave the value of γ of ∼184 × 10 −2 , 123 × 10 −2 and 33 × 10 −2 for BiFe 1− x Cr x O 3 ( x = 004, 006 and 008) nanoceramics, respectively

TL;DR: This work is an overview about the conversion of lignocellulosic biomass into bio-energy products such as bio-ethanol, 1-butanol, bio-methane, Bio-hydrogen, organic acids including citric acid, succinic acid and lactic acid, microbial polysaccharides, single cell protein and xylitol.

TL;DR: In this article, the structural, magnetic, magnetocapacitance and dielectric properties of BiFe1−xNixO3 nanoceramics were reported by the solgel method.
