Removal and Recovery of Rare Earth Elements
Project ID: D2022-17 Rare earth elements (REEs) are critical inputs for advanced technologies including permanent magnets, electronics, clean energy systems, fiber optics, and defense applications. Elements such as neodymium, europium, dysprosium, terbium, and yttrium are particularly important due to their unique magnetic, optical, and catalytic...

Cost-Effective Single-Step Process for the Catalytic Conversion of Methane to Methanol/Formaldehyde
Unmet Need: Currently there is no technology available in the market capable of producing Dimethyl Ether (DME) from methane in a single reactor. DME is an attractive substitute for diesel due to its high cetane number, which is a measure of its ignitibility in compression ignition engines. In addition, DME’s quiet combustion and inability to form...

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•...
