Abstract: Tobacco smoking mixtures capable of producing tobacco smoke are provided which reduce the cytotoxicity and/or mutagenicity of the tobacco smoke. The tobacco smoking mixtures include tobacco cut filler and glycerin in an amount effective to reduce cytotoxicity and/or mutagenicity of smoke produced by the tobacco smoking mixture. The tobacco smoking mixtures enable a further reduction in cytotoxicity and/or mutagenicity when glycerin is combined with palladium or salts of calcium and/or magnesium.

Abstract: An electronic smoking article (100) and a method of preventing unauthorized use of an electronic smoking article (100) are disclosed. The smoking article includes a power supply (120) operable to apply voltage to a heater (144) for heating a liquid; a lock-out feature configured to prevent unauthorized use of the smoking article (100), which disables the power supply to the heater (144) until the lock-out feature is unlocked by an authorized user; a mixing chamber (170) downstream of the heater (144); and at least one air inlet (160) operable to deliver air drawn into the mixing chamber (170), the air being mixed with the volatilized liquid material in the mixing chamber (170) to form an aerosol.

Abstract: A filter component includes a catalyst surrounded by a thermally insulative carbon fiber composite. The catalyst can catalyze the chemical reaction of selected gaseous constituents of a gas stream. During catalysis, the catalyst can reach high temperatures. The carbon fiber composite can contain heat generated during the catalysis within the filter component and thereby reduce heat transfer to the surroundings. The filter component can be used in smoking articles. Methods of making and using the filter-component and methods for treating mainstream tobacco smoke are also provided.

Abstract: Smoke constituent reduction is achieved by resolving from puff-to-puff analysis at which location along a tobacco rod production of a particular smoke constituent is maximized, and locally applying an attenuator at said resolved location to reduce production of the constituent. A remainder of the rod is left untreated so as to minimize impact on taste and burn characteristics of the cigarette. Reduction of the first puff formaldehyde formation is achieved by treating the cigarette tip with salts, using Burley tobacco in the tip, increasing the rod density, ventilation at the tip, and thermal treatment of the tip. Other classes of smoke constituents such as TSNAs (tobacco specific nitrosamines), PAHs (polycyclic aromatic hydrocarbons), etc., in particular the PAHs of naphthalene, phenanthrene, pyrene, flouranthene and benzo(a)pyrene may be reduced with placement of a carbon-based and/or metallic disc at the tip and with practices of the invention herein.

Abstract: Filters and smoking articles include at least one carbon fiber composite molecular sieve sorbent capable of selectively removing one or more selected constituents from mainstream smoke. Methods for making cigarette filters and smoking articles using the carbon fiber composite molecular sieve sorbent and methods for treating mainstream tobacco smoke in a cigarette comprising the carbon fiber composite molecular sieve sorbent are also provided.

Abstract: A system and method for THz imaging utilizing a single THz detector that detects an image of a large area and provides good spatial details (high resolution). In one aspect, the system can individually modulate a different pixel of an image. The system could be a series of masks. Each mask may include holes that may be turned on/off with a distinct pattern from all of the other holes. Once the data for each mask has been received, the data for each hole may be extracted according to its modulation pattern. Another modulation system may include a micro-mirror array that deflects the THz signal towards or away from the THz detector.

Abstract: A system and method for THz imaging utilizing a single THz detector that detects an image of a large area and provides good spatial details (high resolution). In one aspect, the THz beam passes through an object to be imaged, and a THz fiber bundle having a plurality of THz fibers collect the THz beam on the other side of the object and transmit the beams to a single THz detector. Each THz fiber imparts a different time delay to the beam traveling therein. Therefore, the spatial information is converted into time information in the form of time delays. Knowing the distance each part of the imaging area must travel (hence the time it takes) before reaching the THz detector, one can recover the spatial information from the time data. In another aspect, the THz fiber bundle is replaced with a mask having an array of holes with each hole having a different depth or a different refractive index. In still another aspect, the THz fiber array is replaced with a plate holding different masks.
