Apparatus for Dielectric Constant Measurements and Measurements for Water-Methanol Mixtures [PDF]

open access: yes, 1970
A system for measuring dielectric constants has been constructed using a Sargent Oscillometer and an air bath for temperature control. The design and construction of the air bath as well as the temperature control achieved with it are described.

Metal phthalocyanine polymers [PDF]

open access: yes, 1984
Metal 4, 4', 4", 4"'=tetracarboxylic phthalocyanines (MPTC) are prepared by reaction of trimellitic anhydride, a salt or hydroxide of the desired metal (or the metal in powdered form), urea and a catalyst. A purer form of MPTC is prepared than heretofore.
