Nanoparticle-directed and ionically forced polyphosphate coacervation: a versatile and reversible core-shell system for drug delivery.

Werner E G Müller et al.

Scientific reports, 10(1), 17147-17147 (2020-10-15)

A drug encapsulation/delivery system using a novel principle is described that is based on an intra-particle migration of calcium ions between a central Ca2+-enriched nanoparticle core and the surrounding shell compartment. The supply of Ca2+ is needed for the formation

Common-ion effects on the deliquescence lowering of crystalline ingredient blends.

Matthew Allan et al.

Food chemistry, 195, 2-10 (2015-11-18)

Deliquescence points (RH0, RH0mix) of ionic crystalline food ingredients and blends thereof were determined using water activity and moisture sorption techniques. Measured RH0mix values of ingredient blends with and without a common ion were compared to Ross equation predictions of
