    Patent number: 10186412
    Abstract: A novel method and mass spectrometer apparatus is introduced to enable collision induced dissociation inside linear ion traps/guides or 3D ion traps based on digital waveform manipulation. In particular, using the device's digitally produced trapping waveforms to trap, isolate and energize the ions of interest creates a simplified and versatile ion trap/guide that is capable tandem mass spectrometry and high sensitivity. Coupling the digitally operated ion trap/guides to a TOF creates a Q-TOF instrument that outperforms any commercial system in terms of sensitivity and capabilities.

  • STABILIZED PROTEIN FIBER AIR FILTER MATERIALS AND METHODS
    Publication number: 20180311599
    Abstract: Stabilized air filters formed from mats of crosslinked protein-containing fibers are provided. The fibers are formed into a mat with pores that allow air to pass through while physically filtering particulate matter. The protein in the protein-containing fibers also serves to chemically filter polluted air passed through the filter. Specifically, chemical functional groups from the many amino acids that comprise the protein of the protein-containing nanowire react with certain chemical pollutants (e.g., carbon monoxide and formaldehyde) in order to capture or otherwise neutralize the pollutant. Accordingly, the single fiber mat performs two filtering functions. Methods for making the air filters from crosslinked protein-containing nanofibers are also provided.

  • METHOD AND SYSTEM FOR RECYCLING PYROLYSIS TAIL GAS THROUGH CONVERSION INTO FORMIC ACID
    Publication number: 20180273846
    Abstract: This disclosure describes systems and methods for using pyrolysis tail gas as the source for additional hydrogen to be used in the pyrolysis reaction. Tail gas is separated from the pyrolysis products and a portion of the tail gas is converted into formic acid (HCOOH). The formic acid is then injected into the pyrolysis reactor where it becomes the donor of two monohydrogen atoms and is ultimately converted into CO2 under reaction conditions. In this fashion, a closed loop pyrolysis hydrogen donor system may be created utilizing a generally non-toxic intermediary derived from the pyrolysis reaction products. This disclosure also describes using a ruthenium catalyst supported on particles of activated carbon to improve the yield of pyrolysis reactions.

  • Aquaporin 2 protects cattle from ticks and tick-borne parasites
    Patent number: 10052369
    Abstract: A novel method of using an aquaporin protein from Rhipicephalus microplus (RmAQP2), fragments of RmAQP2, and/or the cDNA encoding RmAQP2 and/or the fragments are described. Immunogenic composition containing recombinant RmAQP2 and/or fragments of RmAQP2 are produced and administered to an ungulate which generates an immune response to RmAQP2. After feeding female ticks on the ungulate injected with RmAQP2 and/or fragments of RmAQP2, the female ticks have lower reproductive viability because of a reduced egg mass, reduced hatching percentage, and reduced survival of larvae. Thus, administering RmAQP2 and/or RmAQP2 fragments to an ungulate can reduce the incidence of R. microplus and also reduce the incidence of tick-borne pathogens in ungulates because of the lower number of R. microplus.
