Law of relative dielectric constant of coal under different stresses and gas pressures
In order to study the law of the relative dielectric constant of coal containing gas, the relative dielectric constant of coal containing gas under different stress and gas pressure is studied by using self-made electrical parameter test system, and the ...

Dielectric Constant of Liquids (Fluids) Shown to be Simple Fundamental Relation of Density over Extreme Ranges from - 50^o^ to + 600^o^C, Believed Universal [PDF]
Examinations of past complex theoretical equations describing isothermal dielectric constants (_[epsilon]_) of liquids show that none describe experiments throughout and that only a two-constant equation of density is required.

ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
