Abstract: A composition and method for identifying a microbial composition that inhibits colonization of an enteric pathogen in an animal is disclosed. The method includes removing a microbial sample from a digestive tract of at least one healthy individual, culturing the microbial sample, isolating one or more microbial species within the microbial sample, and identifying one or more isolated microbial species. The method further includes determining one or more bile-tolerant properties of the one or more isolated microbial species, and creating one or more microbial compositions of the one or more isolated microbial species that are bile-tolerant. The method further includes determining an ability of the one or more microbial compositions to inhibit growth of an enteric pathogen in at least one of an assay, and identifying one or more microbial compositions from the one or more microbial compositions capable of inhibiting growth of enteric pathogens in an animal.

Abstract: An improved a device and method for dispersion and simultaneous orientation of nanoparticles within a matrix is provided. A mixer having a shaft and a stator is provided. The shaft may have a rupture region and erosion region. Further, an orienter having an angled stationary plate and a moving plate are provided. The nanoparticles and the matrix are fed into the mixer. A rotational force is applied to the shaft to produce shearing forces. The shearing forces disperse and exfoliate the nanoparticles within the matrix. The dispersed mixture is outputted onto the moving plate. The moving plate is forced across the angled stationary plate to produce fully developed laminar shear flow. The fully developed laminar shear flow or the two-dimensional extensional drag flow orients the dispersed nanoparticles-matrix mixture.

Abstract: An engine oil additive includes carbon nanotubes and boron nitride particulates dispersed within a fluid. The additive is configured to be mixed with a quantity of oil such that the quantity of oil has a concentration from 0.05 to 0.5 grams of carbon nanotubes and of boron nitride particulates per quart of oil to improve the lubricity of the oil. The additive improves the horsepower and torque of the engine while reducing fuel consumption. The carbon nanotubes have an —OH functionalized exterior surface. The carbon nanotubes have a diameter from 1 nanometer to 50 nanometers and have a length from 1 micron to 1000 microns. The boron nitride particulates are hex-boron nitride structures having an average size from 30 nanometers to 500 nanometers.
