the dielectric constant of liquid nitrogen has been determined to have an average value of 1.538 & 0.025. In addition, the dielectric constant of 3 mol% yttriastabiiized zirconia at a frequency of 1 GHz has been determined as 32.99 at room temperature and as 31.73 at 77 K, with an ...
The complex dielectric constant of liquid nitrogen has been measured by a wave guide method in the frequency region 18 to 26 GHz; ε′ = 1.44 and tan δ = 5 × 10. The loss tangent is compared with infrared measurements....

Mixture CM E values are found to be generally less than 0.1% of the mixture CM values for systems containing only nonpolar species. Thus, dielectric constant measurements can be conveniently used as substitute density measurements for simple liquid mixtures. Methods have been developed to utilize ...

In this paper we present accurate, wide range measurements of the dielectric constant of saturated and compressed fluid nitrogen. Measurements were made from 65 to 125 K along the saturated liquid boundary and along selected liquid and gaseous isotherms ranging from 92 to 300 K at pressures to 34...
dielectric constant of liquid water at room temperature and atmospheric pressure is about 80, which is one of the highest values of many solvents. Water at room temperature can dissolvepolar compoundsbut cannot dissolve non-polar compounds such as oil or many kinds of organic compounds. However, ...
Tensile testing showed that the addition of flexible diamines generally improved the elongation at break at both RT and 77K and the tensile strength at 77K. The introduction of D-230 led to a lower dielectric constant at cryogenic temperature than that at RT....
