Abstract
A method of producing particles of materials includes, with a first substance that includes at least one component that is a gas at room temperature and atmospheric pressure, extruding or emulsifying the first substance into or in the presence of a second substance to create a bubble in which the first substance is encapsulated by the second substance and wherein at least some of the first substance is in a gaseous phase, and causing the first substance to condense to a liquid phase, which causes the bubble to transform into a droplet or emulsion. The droplet or emulsion so created is an activatable phase change agent that is stable at room temperature and pressure.
