Journal ArticleDOI
Silver nanoparticles as antimicrobial agent: a case study on E. coli as a model for Gram-negative bacteria
Ivan Sondi,Branka Salopek-Sondi +1 more
TL;DR: These nontoxic nanomaterials, which can be prepared in a simple and cost-effective manner, may be suitable for the formulation of new types of bactericidal materials.
Journal ArticleDOI
Preparation of highly concentrated stable dispersions of uniform silver nanoparticles
TL;DR: Stable concentrated aqueous dispersions of silver nanoparticles of narrow size distribution were prepared by reducing silver nitrate solutions with ascorbic acid in the presence of Daxad 19 (sodium salt of a high-molecular-weight naphthalene sulfonate formaldehyde condensate) as stabilizing agent.
Journal ArticleDOI
Preparation of Uniform Needle-Like Aragonite Particles by Homogeneous Precipitation.
TL;DR: It was found that the formation of different polymorphs of calcium carbonate was affected mostly by agitation and concentration of reactants, as well as by the mixing procedure, and the presence of sulfonate or sulfate ions promoted precipitation of vaterite and calcite.
Journal ArticleDOI
Preparation and the mechanisms of formation of silver particles of different morphologies in homogeneous solutions.
TL;DR: It was found that the isometric and anisotropic silver particles obtained were formed by aggregation of nanosize subunits, which were identified by electron microscopy and X-ray diffractometry.
Journal ArticleDOI
Encapsulation of Nanosized Silica by in Situ Polymerization of tert-Butyl Acrylate Monomer†
TL;DR: In this paper, the presence of the bound MPS agent and the polymer at the silica surface was determined by the attenuated total reflection infrared spectroscopy, while the amounts bound were assessed by the thermogravimetric analysis.
