  • Publication number: 20240130423
    Abstract: The present disclosure provides an aerosol delivery device that may comprise a housing defining an outer wall. The device may further include a power source and a control component, an exit aerosol path defined through an opening, a tank portion that includes a reservoir configured to contain a liquid composition, and an atomization assembly configured to vaporize the liquid composition to generate an aerosol. The atomization assembly may comprise two or more vibrating assemblies each of which includes a mesh plate. In some implementations, the mesh plates may be substantially coplanar and substantially perpendicular to the exit aerosol path. In other implementations, the mesh plates may be non-coplanar.

  • Publication number: 20200281250
    Abstract: A method for preparing an aerosol precursor composition is provided, which includes the steps of providing a first aqueous solution comprising one or more organic acids in water; subjecting the first aqueous solution to hydrolysis to give a hydrolyzed aqueous solution with a higher organic acid monomer content on a dry weight basis than in the first aqueous solution; and combining the hydrolyzed aqueous solution with one or more aerosol formers to give an aerosol precursor composition. Typically, the aerosol precursor composition further contains nicotine. The disclosed method can lead to enhanced control over the composition and characteristics of the produced aerosol precursor composition.
