  • Patent number: 10920187
    Abstract: The present invention relates to a process of remediating wastewaters, preferably agricultural wastewaters resulting from animal production or contained animal feeding operation sites. The water is treated to promote assimilation of nutrients into algal biomass, which can be harvested and sold, and the resultant wastewater is then purified. According to the invention, short wavelength UV radiation (less than 280 nm wavelength) is used to pretreat wastewater, with the dose determined by absorbance of the water, not by bacterial load. Pretreated water exhibits changes in chromophoric dissolved organic matter that allows for improved and increased algae production by as much as 88%.
    Type: Grant

  • Publication number: 20190335755
    Abstract: Method of inhibiting live grazing organisms in an algae composition are disclosed, which do not inhibit the algae. In certain embodiments the concentration of algae increases. In other embodiments the mortality of live grazing organisms is complete. The method contacts an algae composition with wastewater comprising free ammonia and maintaining pH of at least 8 for more than two hours.

  • Patent number: 8507556
    Abstract: A core-shell nanoparticle having a core that includes a fluorophore and a first oxide of a first metal and a shell that includes a second oxide of a second metal such that the first oxide and the second oxide are different. Also disclosed are methods relating to the core-shell nanoparticle.

  • Patent number: 7939560
    Abstract: Multifunctional “smart” nanostructures are disclosed that include fluorescein isothiocyanate (FITC)-encapsulated SiO2 core-shell particles with a nanoscale ZnO finishing layer, wherein an outer ZnO layer is formed on the SiO2-FITC core. These ˜200 nm sized particles showed promise toward cell imaging and cellular uptake studies using the bacterium Escherichia coli and Jurkat cancer cells, respectively. The FITC encapsulated ZnO particles demonstrated excellent selectivity in preferentially killing Jurkat cancer cells with minimal toxicity to normal primary immune cells (18% and 75% viability remaining, respectively, after exposure to 60 ?g/mL) and inhibited the growth of both gram-positive and gram-negative bacteria at concentrations ?250-500 ?g/mL (for Staphylococcus aureus and Escherichia coli, respectively).
