Pickering emulsions are ultra-stable dispersions of two immiscible fluids stabilized by solid or microgel particles rather than molecular surfactants. Although their ultra-stability is a signature performance indicator, often such high stability hinders their demulsification, , prevents the droplet coalescence that is needed for phase separation on demand, or release of the active ingredients encapsulated within droplets and/or to recover the particles themselves, which may be catalysts, for example. This review aims to provide theoretical and experimental insights on demulsification of Pickering emulsions, in particular identifying the mechanisms of particle dislodgment from the interface in biological and non-biological applications.

This systematic review and meta-analysis aim to evaluate the suitability of the reduced Negative Acts Questionnaire (NAQ-R) as an instrument to measure workplace violence in this type of population and synthesize the results of studies that have used it in different industrial sectors. A systematic review was conducted in accordance with the PRISMA 2020 statement.
