Magnetic propertiesThe crystal structure of the novel compound Yb 3Pt 23Si 11 has been determined from powder X-ray diffraction data to be isotypic with cubic Ce 3Pt 23Si 11 (space group F m 3 m; a = 1.68052(5) nm). Magnetic susceptibility, electrical resistivity and heat capacity ...
Methods for the synthesis of chemical compounds having PDE-IV inhibitory activity Disclosed is a process for the preparation of a compound of Formula IV having the structure: ##STR1## wherein R.sub.6 is N(R.sub. 6a) (R.sub.6b); R.sub.3 represents a C.sub.2-8, alkyl which is ...
There exist several reasons to pick out the physics of transition group metals as a separate branch of solid state physics. The first one is the variety of properties of transition metals (TM) and their compounds, which are not only much more complicated, but have some important peculiarities ...
We have synthesized a new compound of a benzothiadiazole central core coupled to terminal thienoimide (TI) via vinyl linker, namely, C8-TI-BT. We investigated physical properties of vacuum-deposited and spin-coated thin films of C8-TI-BT. Optical properties of C8-TI-BT were different between...
