  • Electrochemical Method for the Removal of Heavy Metal Ions from Water Based on Superparamagnetic Nanoparticles

    Type: 
    Product
    Technology:

    Background: This invention relates with removing heavy metal contaminants from water. Cadmium and lead for instance are often present in detectable quantities in drinking water from pesticides and paints respectively which leach into the water system. Technology Description: The technique utilizes superparamagnetic nanoparticles (typically iron-based which are not toxic) functionalized with covalently-bonded surfactants bearing chemical groups that are capable of binding the heavy metal ions reversibly.

  • Method to Prepare IR-activated Photocatalyst Systems and its Applications

    Type: 
    Product

    Photocatalysis offer a variety of applications such as: a non-energy intensive approach for chemical waste remediation self-cleaning applications sterile coatings and processing water purification air purification energy generation and photocatalytic cancer treatment. The current photocatalyst technologies rely on UV radiation to activate the photocatalyst which has its limitations besides being a hazardous form of radiation. Current limitations preventing widespread industrial use of UV activated photocatalytic systems are the low photocatalytic efficiency and scale-up problems.

  • Hydrogen Peroxide Sensing Electrode

    Type: 
    Product
    Technology:

    Background: Hydrogen peroxide (H2O2) is used for environmental and industrial applications—such as drinking water Purification when used as a disinfectant. H2O2 use for environmental applications is not only economical but it also does not produce harmful by-products. Control over the level of H2O2 in a fluid is essential in wastewater treatment. Technology Description: This novel detection probe provides a method for continuous monitoring of H2O2 levels in environmental or industrial fluids.

  • Materials and Methods for Production of Activated Carbons

    Type: 
    Product

    This technology provides materials and methods for the production of activated carbons from biochar where such activated carbons have specific area and pore volume characteristics. The activated carbons may be used for any purpose necessitating the need for them such as water purification air-cleaning solvent recovery catalyst supports and as an energy storage form. They may also be useful in the production of a super anode for a super capacitor or battery.

  • Magnetic Colloid Petroleum Oil Clean-Up of Surface Depth and Shores

    Type: 
    Product
    Technology:

    Challenge: Oil spill contamination cannot be cleaned rapidly and completely from varied environments. Technology: Ferrofluids are colloidal dispersions of magnetic nanoparticles that can be manipulated with an external magnetic field. This invention proposes to apply ferrofluidic principles to the mitigation of oil contamination of solids (wetlands) water surfaces and water sub-surfaces. The particle size surfaces and dispersants can all be optimized for stabilizing oil removal collectability and water purification.

  • Titanium Dioxide (TiO2) Photocatalysts for Water Purification

    Type: 
    Product

    Summary: More and more chemicals of various origins are being discharged into our local water streams ending up at waste and water treatment facilities. These chemicals comprising of pharmaceuticals personal care products and other various industrial chemicals are currently not removed by typical wastewater treatment practices. Further current regulations from the Food and Drug Administration do not require testing or removing these chemicals even as their amounts aggregate in our drinking water.

  • Small Particles for Uranyl Ion Removal

    Type: 
    Product
    Objective:
    Technology:

    Unique particles derived from acrylonitrile or other materials which are capable of selectively absorbing uranyl from groundwater surface water and wastewater.Applications:This technology can be used to improve the quality of a water supply by safely effectively and inexpensively removing uranyl ions from the water. The presence of uranium in groundwater is a growing problem in the United States and one without effective treatment to date. These particles can also be used in portable field systems for analysis of uranyl content on site.

  • Photoelectrocatalytic Oxidation Removal of Contaminants from Aqueous Solutions

    Type: 
    Product
    Objective:
    Technology:

    Chemical contaminants such as nitrogenous wastes found in aquacultures or groundwater may contaminate nearby areas and drinking water supplies. Groundwater pollution may be caused by activities such as industrial waste disposal accidental spills fuel tank leakage or application of fertilizers herbicides or pesticides to crops. Natural causes such as arsenic also may result in groundwater contamination. Organisms are a major cause of water and aqueous environment contamination and are one of the world’s largest health concerns.

  • Nanoparticle-Induced Polymer Assembly

    Type: 
    Product
    Objective:

    This invention provides compositions and methods for inducing and enhancing order and nanostructures in block copolymers and surfactants by certain nonpolymeric additives such as nanoparticles having an inorganic core and organic functional groups capable of hydrogen bonding. Various compositions having lattice order and nanostructures have been made from a variety of copolymers or surfactants that are mixed with nonpolymeric additives.
