    Abstract: This invention provides a hydrophilic porous fiber wick for delivering vaporizable material into the atmosphere, such as a room environment. The wick may be biodegradable. The wick is comprised of a sintered synthetic bicomponent fibers, optionally combined with synthetic monocomponent fibers or natural monocomponent fibers. The wick is optionally treated with plasma or finishing agents for improved hydrophilicity. The wick can wick aqueous and/or non-aqueous-based fragrances or other vaporizable materials and evaporate them into the air without the use of heat, convection air, or atomization.

    Abstract: Functional gel particle formed from a crosslinked polymeric network including a fraction of stable crosslinks and a second fraction of cleavable crosslinks are disclosed. Functional compounds may be chemically or physically encapsulated within and/or released from the gel particle by selective cleavage of the cleavable crosslinks. The functional compounds may be delivered and released to a pre-selected target site. Peripheral or other accessible functionality on the surface of the gel particle allows attachment of a surface reactive agent, thereby modifying one or more surface properties of the gel particle. Processes of preparing the gel particles and processes of delivering the functional compounds to a target site are also disclosed.
