“…The dielectric constant exhibited a continuous decrease with rising frequency at a constant temperature. (Kagdi et al, 2020) also found a decrease in dielectric constant with frequency in samples prepared with ginger root extract and the same results were obtained by (Aziz et al, 2017) for four types of rhizomes from Zingiberaceace families, namely java turmeric ,mango turmeric, black turmeric and tumeric. This decline can be attributed to the decreasing ionic polarization of the viscous components present in the insect bodies as the frequency increases (Shrestha and Baik, 2013).…”

The dielectric properties of dried turmeric finger rhizomes and the related storage insects namely Stegobium paniceum L. (drugstore beetle) and Lasioderma serricorne F. (cigarette beetle), were studied using an impedance analyzer. The measurements were conducted with the frequency range of 25 to 32 MHz and at temperatures ranging from 60 to 80°C. The dielectric constant and loss factor decreased with increasing frequency from 25 to 32 MHz at all temperatures whereas, the dielectric constant and loss factor increases with increasing temperatures at constant frequency for all samples were studied. The sample with maximum moisture content revealed maximum dielectric property. New equations were formulated through regression analysis to explore how the dielectric properties are influenced by changes in temperature and frequency.

“…The analysis of complex modulus plots (M* jωC 0 Z*) can help us have a further understanding of the dielectric behavior of phenanthrene. Two representative Z″ and M″ plots are complementary, the former emphasizes phenomena with large resistance, while the latter shows electrical responses with small capacitance [35,36]. Two semicircle arcs corresponding to the bulk and grain boundary regions of phenanthrene were shown in Figure 7A.…”

Improved Dielectric Properties and Grain Boundary Effect of Phenanthrene Under High Pressure

In situ impedance measurements, Raman measurements and theoretical calculations were performed to investigate the electrical transport and vibrational properties of polycrystalline phenanthrene. Two phase transitions were observed in the Raman spectra at 2.3 and 5.9 GPa, while phenanthrene transformed into an amorphous phase above 12.1 GPa. Three discontinuous changes in bulk and grain boundary resistance and relaxation frequency with pressure were attributed to the structural phase transitions. Grain boundaries were found to play a dominant role in the carrier transport process of phenanthrene. The dielectric performance of phenanthrene was effectively improved by pressure. A significant mismatch between Z″ and M″ peaks was observed, which was attributed to the localized electronic conduction in phenanthrene. Theoretical calculations showed that the intramolecular interactions were enhanced under compression. This study offers new insight into the electrical properties as well as grain boundary effect in organic semiconductors at high pressure.

“…In precise the auto combustion method is widely used due to the controlled size effect of the various samples. This synthesis technique provides a more effective route to the formation of sample at low-temperature, cost-efficient and less timeconsuming [7]. In this perspective, the MgAl2O4 sample has been prepared by using the autocombustion route, and the structural, electrical and dielectric properties were investigated in this study.…”

In the present work, the auto-combustion route was used to synthesized the spinel type magnesium aluminate (MgAl2O4). The structural, dielectric, and electrical properties of the sample have been characterized by using X-ray diffraction, FTIR and dielectric spectroscopy. The X-ray diffraction pattern reveals that the prepared compound has a single-phase cubic spinel structure with space group Fd3m. The crystallite size (D) of the prepared sample was found to be 28.87 nm. The dielectric behaviour of the sample and ac conductivity have been examined in the frequency range of 102 Hz to 105 Hz at different temperatures. It was observed that the dielectric constant and dielectric loss decreases with increasing value of applied frequency due to ceasing effect of polarization and attains a saturated value at a higher frequency range. The ac conductivity shows an increasing nature with frequency followed by charge carrier hopping mechanism.
