Measurements of thermal properties of icy Mars regolith analogs [PDF]

, 2012
In a series of laboratory experiments, we measure thermal diffusivity, thermal conductivity, and heat capacity of icy regolith created by vapor deposition of water below its triple point and in a low pressure atmosphere.

Stripped elliptical galaxies as probes of ICM physics: I. Tails, wakes, and flow patterns in and around stripped ellipticals [PDF]

, 2015
Elliptical cluster galaxies are progressively stripped of their atmospheres due to their motion through the intra-cluster medium (ICM). Deep X-ray observations reveal the fine-structure of the galaxy's remnant atmosphere and its gas tail and wake.

Proton-Ion Conductivity in Hexagonal Wurtzite-Nanostructured ZnO Particles When Exposed to a Reducing Atmosphere

Crystals, 2022
Zinc oxide (ZnO), a direct wide band gap semiconductor (≥3.30 eV), has widespread potential for applications in energy devices and related industries. The initial physical demonstration of ZnO in ceramic fuel cells (CFCs) gave a new view of developing ...

Physicochemical properties of proton-conducting SmNiO3 epitaxial films

Journal of Materiomics, 2019
Proton conducting SmNiO3 (SNO) thin films were grown on (001) LaAlO3 substrates for systematically investigating the proton transport properties. X-ray Diffraction and Atomic Force Microscopy studies reveal that the as-grown SNO thin films have good ...

The Variation of Atmospheric Electrical Conductivity as the Function of Altitude

The International Journal of Innovative Technology and Exploring Engineering, 2020
In the present work we will calculate the electrical conductivity of atmosphere. Generally earth’s atmosphere is about 480 km thick but most of it is within about 16 km. At different altitudes the meteorological conditions are different. In this work we will calculate the atmospheric electrical conductivity at different altitude.
