Abstract: An aerosol-forming substrate comprises a first material and a second material, the first material being comprised in the aerosol-forming substrate as a first plurality of discrete elements and the second material being comprised in the aerosol-forming substrate as a second plurality of discrete elements. The first material comprises an aerosol-former and has a first thermal conductivity, and the second material has a second thermal conductivity that is greater than the first thermal conductivity. The presence of the discrete elements of the second material in the aerosol-forming substrate produces a substrate with augmented thermal conductivity resulting in improvements in aerosol generation and delivery.

Abstract: There is provided an aerosol-forming substrate comprising, on a dry weight basis: between 10 and 90 wt % thermally conductive particles, each thermally conductive particle of the thermally conductive particles having a thermal conductivity of at least 1 W/(mK) in at least one direction at 25 degrees Celsius; between 7 and 60 wt % of an aerosol former; between 2 and 20 wt % of fibres; and between 2 and 10 wt % of a binder. The aerosol-forming substrate has a thermal conductivity of at least 0.22 W/(mK) in at least one direction at 25 degrees Celsius. There is also provided an aerosol-generating article comprising the aerosol-forming substrate and a method of forming the aerosol-forming substrate.

Abstract: The invention relates to a method for the preparation of a homogenized tobacco material, said method comprising: pulping and refining cellulose fibres to obtain fibres having a mean size per weight comprised between about 0.2 millimetres and about 4 millimetres; grinding a blend of tobacco of one or more tobacco types to tobacco particles having a mean size per weight comprised between about 0.03 millimetres and about 0.12 millimetres; Combining the cellulose fibres with the tobacco particles and with a binder to form a slurry; homogenizing the slurry; adding asparaginase to the slurry; and—forming the homogenized to—bacco material from the slurry, wherein the homogenized tobacco material comprises from about 1 percent and about 5 percent in dry weight basis of the binder.
