Interfacial Properties of Powdered Material; Caking in Liquid Dispersions I

Controlled flocculation of coarse suspensions by colloidally dispersed solids I: Interaction of bismuth subnitrate with bentonite

“…Total drug and metabolites were determined by heating the acidified urine for 2 hr a t 100' before extraction, derivatization, and chromatography3. Metabolites were synthesized as reported earlier (1,4).…”

Investigation of a Cellulosic Polymer—Polyhydroxyl Polymer Interacted Polyelectrolyte System I. Rheology and Suspension Characteristics

“…Various methods have been described in the literature as approaches to the stabilization of suspension systems involving rheological control or flocculation. One method involved coating of the insoluble particles to nullify the surface charges, after which they are flocculated under controlled conditions and suspended in a non-ionic vehicle (2)(3)(4)(5). The reduction of the insoluble particle to a very fine particle size and the adjustment of the vehicle density (6, 7) is another.…”
