General description

Morphological and differential thermal analysis of complexes of sodium thiocyanate with poly(ethylene oxide) have been studied. Ionic deep eutectic solvents composed of acetamide+lithium nitrate/sodium thiocyanate have been investigated by dielectric relaxation spectroscopy.

Application

Sodium thiocyanate may be used as a reducing agent in the preparation of monodisperse gold oligoclusters.
