Article Synopsis
  • Radix Glycyrrhizae, derived from the roots of the Glycyrrhiza glabra plant, is a well-known Chinese herbal remedy effective for respiratory issues like coughs and asthma, but its electrical properties are not well-researched due to its complex chemical composition.
  • Analysis using High-Performance Liquid Chromatography (HPLC) found high levels of beneficial compounds such as flavonoids and saponins in Radix Glycyrrhizae, while Fourier Transform Infrared Spectroscopy (FTIR) identified various functional groups contributing to its medicinal properties.
  • The study measured the extract's dielectric and impedance properties, revealing consistent dielectric constants across instruments, but differing loss factor trends at various frequencies, indicating the need for

The mineral composition, crystallinity, and dielectric properties of salts can provide valuable insights into the quality and suitability of different types of salt for various applications. In this study, comprehensive analysis of the X-Ray Diffraction (XRD), X-ray fluorescence (XRF) and dielectric analysis of the Ba'kelalan salt, Himalaya salt and Bamboo salt have been investigated. The mineral composition of these salts, encompassing vital elements such as iodine and other trace minerals, significantly influences the salt's nutritional profile and overall excellence.

Mechanistic studies of the interaction of electromagnetic (EM) fields with biomaterials has motivated a growing need for accurate models to describe the EM behavior of biomaterials exposed to these fields. In this paper, biodegradable bone scaffolds were fabricated using Wangi rice starch and nano-hydroxyapatite (nHA). The effects of porosity and composition on the fabricated scaffold were discussed via electrical impedance spectroscopy analysis.

This study aims to investigate the electric responses (complex modulus and complex impedance analysis) of hydroxyapatite/starch bone scaffold as a function of hydroxyapatite/starch proportion and the microstructural features. Hence, the non-porous and porous hydroxyapatite/starch composites were fabricated with various hydroxyapatite/starch proportions (70/30, 60/40, 50/50, 40/60, 30/70, 20/80, and 10/90 wt/wt%). Microstructural analysis of the porous hydroxyapatite/starch composites was carried out by using scanning electron microscopy.
