Heavy Metal Sensing
VALUE PROPOSITION Heavy metal pollution in soils is widespread in the world, resulting from both natural sources and human activities (e.g., mining and smelting, industrial emission, fossil fuel combustion, etc.). Due to their toxicity, bioaccumulation, and environmental persistence, elevated levels of heavy metals in the environment pose major threats...

Biobased Films with Improved Oxygen Barrier
Executive Summary Biobased materials such as polybutylene adipate terephthalate (PBAT), polyglycolic acid (PGA) and polybutylene succinate (PBS) are attractive materials for packaging films due to their positive sustainability aspects including biodegradability. However, their oxygen barrier properties limit the use of these materials to certain applications....

Biodegradable Barrier Coating for Paper
Executive Summary Coated paper is used in a variety of packaging applications including fresh produce, cheeses, confectionary, frozen fish and fast food. To achieve sufficient barrier properties, the paper is often coated with petroleum based waxes or polyfluorinated substances (PFAS). However, these coatings are not environmentally attractive and...

Assay for Detecting and Quantifying Coccidioides
Researchers at TGen and Northern Arizona University (NAU) have developed a real-time qPCR assay for detecting and quantifying Coccidioides immitis and Coccidioides posadasii. The highly sensitive and specific assay can be used by clinicians in rapidly diagnosing Coccidioidomycosis. This assay can be particularly useful outside of the endemic regions...

Efficient Room Temperature, Ambient Pressure Liquid Ammonia Storage System
Executive Summary Liquid ammonia is current stored and transported in very large quantities in refrigerated units, railcars, tanker trucks and pressurized containers. While the majority of existing uses are as a nitrogen fertilizer for agricultural uses, increasing attention has been turned to ammonia as a green, carbon free energy storage medium for...

Energy Fishing using Moving Wind Turbine System
Offshore wind turbines are typically fixed devices anchored to the seabed by a foundation. The advantages of a floating offshore system (economic, reusable, deeper water depths) as compared to fixed structures have resulted in increased interest in floating technologies. The major type of floating wind systems in use today are semisubmersible and concrete...

Sustainable Chain Extenders for Recycling Polyesters
Executive Summary Polyesters comprise a significant portion of plastics entering landfills. One issue that limits their recycling is degradation during melt processing which lowers their molecular weight and melt viscosity. Reactive chain extenders are often used in this case to build back the molecular weight of the polyester during reprocessing....

Tunable Degradation of Fibers
­ Executive Summary Degradation of polymeric materials is an important process in recycling, composting and rendering them innocuous to the environment. Controlling the rate by which the materials degrade remains challenging and impacted by the nature of the materials and their use in applications where combinations of materials exist to fulfil...

Process for Depolymerizing Recycled Polystyrenes
­Executive Summary Each year, billions of lbs of polystyrene and styrene copolymers are discarded as waste and very little is recycled. While some technologies have attempted pyrolysis in fluidized bed reactors or solvent processes to convert the polystyrene back to monomer, high costs, long process times and a myriad of reaction products have...
