Analysing Attenuation Losses of a Power Line Cable [PDF]

Journal of Electrical and Electronics Engineering
This research focuses on the determination of the channel frequency response losses for a length of power cable, which is crucial in determining the channel bandwidth performance. The parameters of the power line cable model are determined by measurement.

Electrophysical properties of the Rochelle salt dispersed in a porous dielectric matrix of type A zeolite

Physics of Complex Systems
Electrical conductivity, real part of dielectric permittivity and dielectric losses of a novel nanocomposite material obtained by the infiltration of a NaA zeolite matrix with Rochelle salt were studied in the frequency range from 100 Hz to 100 kHz.

Spontaneous radiation of a finite-size dipole emitter in hyperbolic media [PDF]

, 2011
We study the radiative decay rate and Purcell effect for a finite-size dipole emitter placed in a homogeneous uniaxial medium. We demonstrate that the radiative rate is strongly enhanced when the signs of the longitudinal and transverse dielectric ...

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

Advanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

Water determines the intramolecular dynamics of proteins. En example of bovine serum albumin

Frontiers in Chemistry
In this work, the terahertz time-domain spectroscopy method analyzed solutions of bovine serum albumin (BSA) in two high concentrations (50 and 334 mg/mL) at three pH values (2.5, 6.5, 8.5) and the same solvents without protein, at 25°C.

Dielectric loss in porous TiO2 [PDF]

Ceramics International, 2017
Abstract The dielectric loss behavior of TiO 2 was characterized on samples of variable porosity and variable pore size. Pores were formed by two methods: varying the sintering temperature and by the addition of a spherical carbon porogen. Porosities varied from 5.9% to 59.3%.
