  • Publication number: 20220362696
    Abstract: A product and method of manufacturing and producing antimicrobial fibers using an antimicrobial additive material. The method comprising using various antimicrobial metals incorporated and embedded into an inorganic material as metal ions within the additive material that can be formulated into a masterbatch precursor material and processed to manufacture fine or synthetic fibers using standard manufacturing processes for use in applications from face masks and respirators to air filters for HVAC and higher efficiency HEPA applications.

  • Publication number: 20220347621
    Abstract: A method for removing at least one odorous contaminant from a fluid stream by filtering the fluid stream with a filtration medium. The filtration medium includes a chemically modified activated carbon. The method is useful for removing one or more volatile organic compounds and/or one or more volatile thiol compounds, particularly terpenes (e.g., alpha-pinene and myrcene), nonanol, decanol, o-cymene, and benzaldehyde from the fluid stream. In some embodiments, the fluid stream is a cannabis grow house exhaust stream.

  • Patent number: 11130691
    Abstract: Techniques are described for preparing a water filtration composition that includes activated carbon having an ash content of at least 10 wt. % and particles of a solubilizing agent. The solubilizing agent forms a water-soluble complex with cations (e.g., calcium ions). This increases the solubility of calcium ions and other scale-forming ions in water, thus suppressing scale formation on interior surfaces of water processing infrastructure. The activated carbon and the solubilizing agent are processed to have particle sizes in a same range, thus enabling the activated carbon and the solubilizing agent to be thoroughly mixed together.

  • Publication number: 20110293674
    Abstract: The present invention relates to the identification of microRNAs that regulate smooth muscle cell proliferation and differentiation, including the miR-143/miR-145 cluster. Methods of treating restenosis and neointima formation by increasing expression of miR-143 and/or miR-145 are disclosed. The present invention also relates to the identification of two microRNAs, miR-486 and miR-422a, that regulate cell survival in the heart. Methods of treating or preventing cardiac hypertrophy, heart failure, or myocardial infarction by increasing expression of miR-486 and/or miR-422a in heart tissue are also disclosed.
