The A-site substituted double perovskite oxides (DPOs) have in the recent decades gained much attention due to their various interesting properties and possible applications. For this reason, R2CoMnO6 (R = Nd, Y, Ho, and Er) DPOs have been synthesized using the auto-combustion sol-gel method. X-ray diffraction analysis suggests the crystal structur...

We present the results of a study aimed at investigating the effects of electric fields on quasi-static bubble departure dynamics during pool boiling of perfluorohexane (FC-72) in microgravity conditions. Analysis was performed through an alternative formulation of the bubble momentum balance in which the contribution of non-uniform electric stress...

A comprehensive study on the mechanism of ac-charge transport and dielectric relaxation in the MnNb2O6 columbite system has been reported. Thermally driven, Arrhenius-like behaviour of the ac-conductivity (σ(ω,T)) is predominant at temperatures above 300 K in the frequency range 50 Hz–5 MHz with activation energies (Eac) lying between 0.45 and 0.38...

In this report, Co2+ and Al3+ doped M-type Ba-Sr hexagonal ferrite has been synthesized using sol-gel method. The crystal structure and grain morphology have been examined by x-ray Diffraction (XRD), and Field Emission Scanning Electron Microscope (FESEM). The optical band gap of the prepared compositions was determined by ultra violet visible spec...

Electrostatic Force Microscopy has been proven to be a precise and versatile tool to perform quantitative measurements of the dielectric constant of thin film domains in the nanometer range. However, it is difficult to measure non-planar nanostructures because topographic crosstalk significantly contributes to the measured signal. This topographic ...

Knowledge of the thermal and dielectric properties of wolfberries is essential for understanding the heat transfer and the interaction between the electromagnetic field (10-3000 MHz) and the sample during radio frequency (RF) and microwave (MW) drying. The thermal and dielectric properties of wolfberries were determined as influenced by moisture co...

The soil dielectric constant model reflects the relationship between the volumetric water content and the dielectric constant. The ground penetrating radar (GPR) could quickly, precisely and non-destructively obtain the water state of the soil layers. A reasonable and reliable dielectric constant model is of great significance for predicting, monit...

The NdFeO3-SnO2 nanocomposite was successfully prepared using a solid-state reaction route. The dual-phase (orthorhombic and tetragonal) in the NdFeO3-SnO2 composite was confirmed by XRD and then analyzed by Rietveld refinement. In the Raman spectrum, the A1g and B2g modes of SnO2 were observed at 650 cm−1, and 770 cm−1, and 7Ag and 1B1g modes of N...
