Centrifugation Potentials in Sols of Silver Iodide

Influence of Sodium and Iodide Ions on the Transformation of Metaphasic Silver Iodide into the Crystalline Silver Iodide

The influence of constitutive (Agl, lions) and nonconstitutive (Na+ ions) components of silver iodide hydrosols on the transformation rate of metaphasic silver iodide into crystalline silver iodide is studied. The simultaneous change of Agl, l ions, and Na+ ions concentrations causes a complex change of the value of the constant k, (which is proportional to the aggregation rate constant k 2). W...

Aqueous Extracts of Seeds as Agents in the Preparation of Silver Sols.

M\1any methods have been suggested for the preparation of colloidal metals by condensation with the use of organic compounds as stabilizers (1). Among these compounds may be mentioned gum arabic, gelatin, sugar, glycerol, sodium citrate, saponin, barium arabinate, sodium protalbinate, and sodium lysalbinate. Probably colloidal silver has received as much attention as has colloidal gold. Wool-fa...

The reaction of yeast alcohol dehydrogenase with iodoacetamide as determined with a silver-silver iodide electrode.

Adsorption and Surface-Enhanced Raman of Dyes on Silver and Gold Sols'

Several negatively charged dyes were investigated for their possible adsorption on the surface of silver and gold colloidal particles. Those dyes that were found to adsorb on the particles were then checked for surface enhancement of Raman scattering. Highly efficient surface-enhanced Raman scattering (SERS) was observed from a carbocyanine dye in both sols. Excitation-dependence studies as wel...
