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•...
