  • Patent number: 10383357
    Abstract: Aspects of the present disclosure relate to electrochemical reduction of tobacco-specific nitrosamines (TSNAs). According to certain methods described herein, a tobacco composition containing one or more TSNAs and nicotine is contacted with a solvent to form a tobacco mixture. In some embodiments, the tobacco mixture is introduced into an electrochemical device comprising an anode and a cathode. The tobacco mixture may, in some cases, form at least part of an initial electrolyte mixture that is in physical contact with at least a portion of the anode and at least a portion of the cathode. In some instances, an electrical potential is applied between the anode and the cathode, thereby reducing one or more TSNAs in the initial electrolyte mixture and producing a reduced electrolyte mixture. In certain cases, application of the electrical potential between the anode and the cathode does not cause non-TSNA components of the tobacco mixture (e.g.

  • Patent number: 8772197
    Abstract: One aspect of the present invention relates to reactive compositions and methods of use thereof, wherein a metal oxide cluster is used to connect a reactive group (or groups) to the surface of a substrate. In certain embodiments, the reactive group in the compositions decomposes organophosphate agents through nucleophilic hydrolysis. In certain embodiments, the reactive group in the compositions is bactericidal. Remarkably, the use of metal oxide clusters in the disclosed compositions and methods permits incorporation of higher quantities of nucleophilic and bactericidal groups without the difficulties associated with having to pretreat the substrate prior to its association with the reactive groups.

  • Patent number: 8684189
    Abstract: Described is the application of layer-by-layer (LbL) electrostatic assembly techniques to electrospun nanofibers in order to fabricate novel, breathable electrospun fiber-based chemical and biological detoxifying protective fabrics and filters. The combination of layer-by-layer electrostatic assembly and electrospinning technique allows one to take advantage of high specific surface area, light weight and breathability of electrospun fiber mats while simultaneously providing the versatility to incorporate different functional polyelectrolytes to achieve multifunctional coatings for both chemical and biological protection together. The functionalized fiber mats can be incorporated into breathable chemical and biological protective fabrics, filters and masks. In addition, LbL electrostatic coating of porous non-woven materials provides the versatility to generate multifunctional polymer-based membrane materials for other applications.

  • Publication number: 20130343969
    Abstract: Extraction method for recovering metals. Phosphoric acid is contacted with an extractant suspension of solid particulate material comprising a para- or ferromagnetic material core surrounded by an outer shell of a chelating polymer whereby a metal is the solution is adsorbed on the chelating polymer, thereby removing it from the phosphoric acid solution. The metal-containing solid particulate material is magnetically separated from the solution and the metal is stripped from the solid particulate material for reuse.

  • Patent number: 8436116
    Abstract: One aspect of the present invention relates to polymers containing redox-responsive moieties (such as, ferrocene). In certain embodiments, the present invention relates to in-situ continuous separation systems which use such redox-responsive polymers for low-molecular weight alcohol removal from an aqueous mixture; such systems enhance the production of low-molecular weight alcohols by reducing the product inhibition effects that plague their production from bio-mass by fermentation.

  • Patent number: 7598199
    Abstract: The present invention relates to compositions and methods for sorbing (e.g., adsorption and chemisorption) and destroying organophosphate chemical agents. In certain embodiments, the invention contemplates the use of finely divided, modified nanoscale metal oxide particles. In one embodiment, a suspension of magnetite (Fe3O4) nanoparticles modified with 2-pralidoxime or its polymeric analog, poly(4-vinylpyridine-N-phenacyloxime-co-acrylic acid), catalyzes the hydrolysis of organophosphate compounds at a neutral pH. The oxime-modified magnetite particles serve as a nano-sized particulate carrier with a powerful ?-nucleophile, an oximate group, immobilized on its surface. The oxime-modified magnetite nanoparticles are colloidally stable at neutral pH and they are readily recovered from the aqueous milieu by high-gradient magnetic separation methods.
