Removal and Recovery of Rare Earth Elements

Project ID: D2022-17 Background Rare earth elements (REEs), such as neodymium, europium, dysprosium, terbium, and yttrium, are sometimes referred to as the “vitamins of modern industry” due to their frequent use in high-tech applications. They are used in fiber optics to carry internet traffic, making gasoline from petroleum, and in items...

Emulsion Formation using corona discharge and electrohydrodynamic pumping

Project ID: D2020-22 Background Making water-in-oil emulsions often requires high pressure, ultrasonication, or sensitive inversion techniques that may still only result in a semi-stable colloid. In addition to emulsion shelf life, these techniques have drawbacks, such as having high-energy consumption and narrow/sensitive production parameters, needing...

Monolithic bifacial perovskite-CdSeTe tandem thin film solar cells for harvesting light from the environment

Project #D2021-04Invention DescriptionThe University of Toledo has developed a new tandem solar cell design — the bifacial tandem (Fig. 1) that enabled the first realization of a working monolithic tandem solar cell comprising wide-bandgap metal halide perovskite and narrow-bandgap cadmium selenide telluride (CdSeTe, or CST). The bifacial strategy...

Novel Class of Materials for Boron Extraction

Project ID: D2009-11 Background Solid Phase Microextraction (SPME) has gained widespread acceptance and use in laboratories due to the fact that it is a solvent-less extraction technique, its mode of operation is relatively simple, easy to automate, and sampling and sample preparation are combined into one step. Until now, methods that coat SPME...

Functionally graded graphene transient electronics

Project ID: D2018-22Background It is estimated that electronics account for 42 million tons of waste per year worldwide. As a result, electronic manufacturers have become interested in transient electronics. They contain environmentally benign components that can be degraded over time in a natural environment. Transient electronics can be used to better...

Enhanced Anti-Fouling Properties of Novel Composite Material

Project ID: D2013-31 Novelty: Development of a novel electromagnetic polymer composite material for enhanced anti-fouling effects. Background: Biofouling (bacterial attachment to solid surfaces and colonization) is the main source of bacterial infection and poses potentially harmful impacts on human health. Medical devices, food packaging, and drinking...

Constrained geometry catalysts for the production of polymers

Project ID: D2009-89 Background Polymerization reactions are used in industry to make widely used products, such as polyolefins. There has been an interest in improving control over polymer tacticity and co-polymerization, leading to the development of Constrained Geometry Catalysts (CGCs). The CGCs form complexes with a pi-bonded moiety bridged...

Additive for improved stability of perovskites against water

Project ID: D2019-50 Background Perovskites are commonly used in photovoltaics, LEDs, and water splitting devices. Despite success in increasing cell efficiencies using perovskites, their instability against moisture limits their practical application. Incorporating hydrophobic materials into the perovskite has been used to mitigate this problem,...

Pyrrole-Based Composites for Metal Extraction and Analysis

Project ID#: D2018-57Invention DescriptionThe researchers at the University of Toledo have developed a chelating polypyrrole powder that can be used for filtration by directly mixing with samples and passing the sample through a filter. Desorption is then accomplished by simply dropping the pH. Applications• Selective microextraction devices•...

Pressure sensitive polymer films with reversible porosity

Project ID: D2018-23BackgroundPressure sensing is used in the automobile, packaging, food, and pharmaceutical industries. Commercially available pressure-sensing films rely on a reaction created when microcapsules burst upon applied pressure. However, these films only function in a limited temperature range and do not work in wet or oily environments....
