In this paper, the electrical properties of various compacted carbon nanomaterials were investigated. Compacted (carbon nanofibers, multi-walled nanotubes) into cylindrical samples and measured in a frequency range from 50 Hz to 1MHz.

In this paper, dielectric measurements were carried out to obtain conductivity, permittivity (real and imaginary parts) loss tangent of Dead Sea water. These properties measured using two different methods: Vector Network Analyzer “VNA” (Dielectric Assessment Kit “DAK”) Four Probe method, all taken at room temperature (25˚C). The collected data has been analyzed in the frequency range (200 MHz ...

silver nanoparticles (nps) have been the subjects of researchers because of their unique properties ( e.g., size and shape depending optical, antimicrobial, and electrical properties). a variety of preparation techniques have been reported for the synthesis of silver nps; notable examples include, laser ablation, gamma irradiation, electron irradiation, chemical reduction, photochemical methods...

harvesting of timber using ground based machinery is still a common practice around the world. track and road building, and movement of machinery during harvesting operations cause soil disturbance. therefore the aim of this study was to investigate the change in soil properties after logging operation on skid trails (2 years and 7 years after logging) and compare disturbed soil properties with...
