Abstract: Designs and arrangements for sublimation cells are provided, which enriches an inert carrier gas with organic vapor such that the partial pressure of the organic vapor is highly stable in time. Stability is achieved by controlling the local rates of evaporation along the solid-gas interface through one or more crucibles, thereby reducing the effects of greater headspace and lowering interfacial area as the source depletes. Local evaporation rates also can be controlled using either temperature distribution or convective flow fields.

Abstract: Systems and techniques for depositing organic material on a substrate are provided, in which one or more shield gas flows prevents contamination of the substrate by the chamber ambient. Thus, multiple layers of the same or different materials may be deposited in a single deposition chamber, without the need for movement between different deposition chambers, and with reduced chance of cross-contamination between layers.

Abstract: The present invention generally relates to novel biomarkers and their methods of use for identifying and treating e-cigarette, or vaping, product use-associated lung injury (EVALI).

Abstract: A portable cigar holder for golfers, small and comfortable enough to be carried in the golfers pocket, designed for insertion into the ground or the spare-tee-holding-holes in most golf carts. Constructed in one piece, the holder has a tapered tee section (5) for securing the holder in the ground or spare-tee-holding holes in a golf cart. A cup section (4) with an internal pin (6) holds cigars of varying widths securely in the vertical plane. The internal pin (6) serves to both pierce the cigar for smoking and allows the holder to securely hold cigars of varying widths.
