Method for Processing Reactive/Nonreactive Materials Using Binder Agent

Novel Binding Agent Removal Process Background Existing binder jetting processes struggle with completely removing the binder, which leads to residual carbon that affects product quality. Residual carbon, originating from the binder, poses significant challenges, particularly for reactive materials such as nickel-titanium ((NiTi) alloys and for other...

A new design of high performance elastocaloric system by additive manufacturing

Solid-State High-Performance Cooling System Background Refrigeration and air conditioning currently account for approximately 17% of total global electricity consumption and approximately 40% of building energy consumption. Hydrofluorocarbons used in 99% of current cooling systems are green house gases that warm at a rate 100s of times greater than...

Nanoparticle Clay Slurries

Project ID: TECH2024-26 Background Shear thickening refers to the phenomenon in rheology where the viscosity of a fluid increases as the rate at which the fluid is deformed by a shearing force (i.e., the shear rate) increases. When more force is applied to the fluid, the fluid becomes more resistant to flow. Shear thinning is when the viscosity decreases...

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...
