Role of Filler-Polymer Interface on the Thermal Conductivity in Polymer Composites
Abstract: Polymers with high thermal conductivity are the need of modern technologies due to their robustness, cost-effective, and less corrosiveness. However, bare polymers are not good heat-conductors due to their molecular structures, and their non-metallic properties. Therefore, metallic fillers of different shape and size have been used to enhance the thermal conductivity in polymer-composites. However, there has been search of best geometrical fillers which can maximize the thermal conductivity effectively with …

Historical Review of Ionosphere in Perspective of Sources of Ionization and Radio Waves Propagation
Abstract: Before the discovery of ionosphere, the electronic communication was not possible at a distance greater than 100 km due to the curvature of Earth; but after its discovery, the ionospheric wave propagation made possible the electronic communication at even more than 3000 km via reflection of radio waves through ionosphere. The ionosphere is electrically neutral, ranging from 50 to 1000 km in altitude and outer limit can exceed to 3000 …
