Abstract: A method of making a nicotine containing sheet is provided, including steps of combining a source of nicotine salt having a cellulose content of less than about 5% by weight on a dry weight basis with a separate source of fibrous material having a nicotine salt content of less than about 5% by weight on a dry weight basis to form a mixture; and drying the mixture to form a sheet.

Abstract: An inhaler article includes a body extending along a longitudinal axis from a mouthpiece end to a distal end and a capsule cavity defined within the body. A mouthpiece air channel extends from the capsule cavity to the mouthpiece end. An end cap is disposed within the distal end and extends to the capsule cavity. The end cap extends from an end cap distal end to an end cap inner end. The end cap includes an air channel extending from the end cap distal end to the end cap inner end. The air channel is non-parallel with the longitudinal axis.

Abstract: A cartridge for an aerosol-generating system is provided, including an elongate first compartment having a length L1, a maximum transverse cross-sectional area A1, a first air inlet, and a first air outlet, and containing a nicotine source including a first carrier material loaded with between about 1 mg and about 50 mg of nicotine; and an elongate second compartment having a length L2, a maximum transverse cross-sectional area A2, a second air inlet, and a second air outlet, and containing an acid source. The first and second compartments are arranged in parallel within the cartridge and the ratio (L1)2:A1 is at least about 12:1 and the ratio (L2)2:A2 is at least about 12:1. An aerosol-generating system is also provided, including the cartridge; an aerosol-generating device including a housing defining a cavity to receive at least a portion of the cartridge; and a heater to heat the first and second compartments.

Abstract: A method and apparatus is disclosed for providing shear-induced alignment of nanostructures, such as spherical nanodomains, self-assembled nanodomains, and particles, in thin films, such as block copolymer (BCP) thin films. A silicon substrate is provided, and a thin film is formed on the substrate. A pad is then applied to the thin film, and optionally, a weight can be positioned on the pad. Optionally, a thin fluid layer can be formed between the pad and the thin film to transmit shear stress to the thin film. The thin film is annealed and the pad slid in a lateral direction with respect to the substrate to impart a shear stress to the thin film during annealing. The shear stress aligns the nanostructures in the thin film. After annealing and application of the shear stress, the pad is removed, and the nanostructures are uniformly aligned.
