particle diameter that undergoes a transformation with time and larger nanoparticles
and nanorods are formed with 30 diameter and 100 length. The application of more
dilute thioglycerol solution (0.01 M) leads directly to the spherical particles with a
diameter of about 50 nm and a crystalline form corresponding to a covellite-type
hexagonal phase.
