Patents by Inventor Holly C. Axtell

Holly C. Axtell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20080161631
    Abstract: A reactive-adsorptive protective material having an activated carbon adsorbent for adsorbing chemical impurities, wherein nanoparticular entities are loaded into and onto a surface of said activated carbon adsorbent to further impart chemically reactive and biocidal properties onto the activated carbon for providing protection against chemical and biological agents in the atmosphere. Advantageously, a superior reactive-adsorptive material is provided having the ability to kill microorganisms in addition to the ability to neutralize and decompose chemical substances, while at the same time not diminishing the adsorptive/reactive capabilities and effectiveness of either the substrate carbon or the loaded nanoparticular entities used.
    Type: Application

  • Patent number: 7268269
    Abstract: A reactive and adsorptive (i.e., multi-functional protective) textile and methods for constructing and using same which possess at least chemically reactive and biocidal properties. Nanoparticles from different classes such as metal oxides, metal hydroxides, metal hydrates and POMs are incorporated into elements which can be utilized in a wide variety of protective materials. The nanoparticles may be treated to reduce water solubility or combined with halogens, alkali metals or secondary metal oxides to specifically engineer the nanoparticle to address a particular chemical or biocidal threat.

  • Patent number: 7256156
    Abstract: A reactive-adsorptive protective material having an activated carbon adsorbent, including those manufactured from a gel-type ion exchange resin. The activated carbon adsorbent has adsorptive properties for adsorbing chemical impurities. The activated carbon is wettlerized to further impart reactive properties onto the activated carbon for providing protection against blood agents in the atmosphere. Advantageously, a superior reactive-adsorptive material is provided having the ability to neutralize chemical substances, in particular, blood agents, while at the same time not diminishing the effectiveness of the carbon's adsorption capabilities.
