Abstract: Apparatus and methods for reducing or eliminating undesirable air-borne substances, such as odors, bacteria, viruses, fungi, and toxins, are provided. A filter containing nanocrystalline metal oxide or metal hydroxide particles may be installed within an air handling apparatus such as an existing HVAC unit located within a building, and particularly within a home, or a portable air processor or purifier. The air handling apparatus comprises a blower which pulls air containing various undesirable substances from within the enclosed environment and directs it through a filtering device containing the nanocrystalline particles. The undesirable substances are sorbed by the nanocrystalline particles thereby creating a deodorized stream of air that may then be directed back into various portions of the enclosed environment or vented to the atmosphere.

Abstract: A tobacco product comprising nanocrystalline particles and methods of reducing the levels of undesirable compounds in tobacco smoke are provided. The nanocrystalline particles are effective sorbents of numerous toxic compounds released by burning tobacco and may be incorporated into the tobacco itself, incorporated into a filter element, or incorporated into the fibers of a wrapping paper.

Abstract: This invention relates to fast-drying RF inkjet composition and apparatus for inkjet printing RF inkjet compositions. The compositions and apparatus are useful for inkjet printing onto a variety of media including both porous and non-porous substrates. The RF inkjet composition desirably includes RF susceptors combined with polar carriers which may be activated by RF energy to generate heat within the RF inkjet composition, resulting in enhanced evaporative drying.

Abstract: The present invention provides methods of drying radiofrequency-activatable inkjet inks, methods for customizing the radiofrequency parameters of an RF source based on pre-selected printing conditions, and methods for selecting or formulating an RF inkjet ink composition based on pre-selected printing conditions and/or printing equipment. The invention further provides radiofrequency-activatable inks having customized radiofrequency susceptibility profiles and to sets of such radiofrequency-activatable inks.
