    Abstract: An electrically operated aerosol-generating system may include a liquid storage portion configured to store a liquid from which aerosol may be generated, an electric heater, a capillary wick extending between the liquid storage portion and the electric heater and configured to convey liquid from the liquid storage portion to the electric heater and electric circuitry connected to the electric heater. The electric circuitry may be configured to: activate the electric heater for a first heating time period in response to an input to vaporize liquid in the capillary wick, activate the electric heater for a second heating time period upon the elapse of a first cooling time period after the first heating time period, record a temperature measurement of the electric heater during the second heating time period, and determine an amount of liquid in the liquid storage portion based on the temperature measurement.

    Abstract: There is provided a cartridge for an aerosol-generating system, the cartridge comprising a container comprising an outer surface and an inner surface, wherein the container outer surface at least partially defines an outer surface of the cartridge. The cartridge also includes a susceptor material comprising a susceptor material inner surface at least partially defining a cartridge cavity, the susceptor material inner surface defining a plurality of interstices. The cartridge also includes an aerosol-forming substrate in the form of a gel at room temperature, plurality of interstices are configured to hold the gel.

    Abstract: An exemplary smoking article includes a smoking rod filled with a combination including tobacco filler material and cellulose filler material. The tobacco filler material and cellulose filler material can be arranged such that the constituent material particles are generally distributed throughout the smoking rod, the tobacco filler material at least partially surrounds the cellulose filler material along a length of the smoking rod, and/or the cellulose filler material particles have a higher concentration along a central axis of the smoking rod than the tobacco filler material particles.
