Patent application number | Description | Published |
20080296530 | Nanostructured magnetorheological fluids and gels - Magnetorheological materials having a supramolecular polymer gel as a component of the carrier are disclosed. Useful supramolecular polymers for gels include those having bipyridine or terpyridine ligands which can participate in metal coordination bonding. The magnetizable particles of magnetorheological materials can have supramolecular surfactant-polymer coatings. | 12-04-2008 |
20110033776 | PROTON EXCHANGE MEMBRANES - The present invention is directed to proton exchange membranes such as for use in fuel cells. In one embodiment, a polyetherquinoxaline is obtained by reaction between a haloquinoxaline and at least one diol, which forms a repeating unit including an ether linkage. The polyetherquinoxaline is suitable for use in a proton exchange membrane, which can be used in a fuel cell. | 02-10-2011 |
