摘要： The invention provides a modified adsorbent material impregnated with a metal oxide, which can be used in a filter element adapted for use in a smoking article. The modified adsorbent material exhibits increased filtration efficiency with respect to certain gas phase species of mainstream cigarette smoke. Exemplary adsorbent materials that can be modified according to the invention include activated carbon, molecular sieves, clays, ion exchange resins, activated aluminas, silica gels, meerschaum, and mixtures thereof. One example of a metal oxide is cerium oxide. Impregnation with a metal oxide can be accomplished by directly treating the adsorbent with a metal oxide or impregnating the adsorbent with a metal oxide precursor, such as cerium nitrate, followed by calcining the impregnated material to convert the precursor to the desired metal oxide. Methods of forming the modified adsorbent material and smoking article filters incorporating the modified adsorbent material are also provided.

摘要： The present invention provides a conductive substrate useful for Joule heating, such as in an electronic smoking article. Particularly, the invention provides a resistive heating element formed of a conductive substrate. The conductive substrate comprises an electrically conductive material and a carbonaceous additive, such as a binder material. The conductive substrate is carbonized in that it is subjected to calcining conditions to effectively reduce the carbonaceous additive to its carbon skeleton. It has been found that such carbonized substrate has surprisingly improved resistance properties in relation a substrate of the same formulation that is not carbonized. The carbonized substrate can include an aerosol precursor material. The formed resistive heating element can be included in an electronic smoking article to simultaneously provide resistive heating and aerosol formation with a single, unitary component.

摘要： A smoking article, such as a cigarette, includes a carbonaceous heat source. A mouth end piece segment is located at the mouth end of the smoking article, and the mouth end piece segment allows the smoking article to be placed in the mouth of the smoker to be drawn upon. The smoking article further incorporates an aerosol-generating segment located between the heat generation segment and the mouth end piece segment. The aerosol-generating segment incorporates an aerosol-forming material (e.g., glycerin and flavors). The heat generation segment is in a heat exchange relationship with the aerosol-generating region such that heat generated by the burning fuel element acts to volatilize aerosol-forming material for aerosol formation. The carbonaceous heat source is in intimate contact with coarse, fine or ultrafine particles of materials such as cerium oxide, or mixtures of cerium oxide and palladium chloride.
