Is anybody aware of a special interaction of amidated pectins with silica except depletion flocculation?

I observed as one may expect depletion interaction between amidated pectin (degree of esterification 28 - 34%, degree of amidation 16 - 22%) in solution (natural pH, deionized water) with...

Does sonication favor o/w emulsions over w/o emulsions?

I wonder whether by sonication of let's say, a 1/1 paraffin oil (viscosity 250 mPa*s, density 0.87 g/cm³) o/w is favored also for emulsifiers like Span 20 (1 % m/m emulsion). May it be that...
