The paper presents a study concerning the preparation and characterization of a new type of composite powders as silver nanoparticles deposited on ZnO microcrystalline particles. This system is destined to antifungal applications. The preparation procedure is based on the reduction of the Ag+ from an AgNO3 solution containing the fine dispersed ZnO particles. The method allows the achievement of spherical silver nanoparticles having an average diameter of 16.5…88.5 nm. The silver nanoparticles weight content varied between 0.1…25 wt. %. AAS, UV-Vis spectroscopy, dynamic light scattering technique, TEM and SEM analyses were carried out for chemical and morphological characterisations. The antifungal assay by the antibiograme method has demonstrated that these composite powders are suitable for health care and consumer goods items.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
