Publication number: 20190252706Abstract: A self-healing ceramic ion-selective membrane assembly including a ceramic ion-selective membrane, and at least one additive layer. The at least one additive layer includes an ionic ceramic material which is porous or ion-selective. The at least one additive layer having a metal cation diffusivity higher than the metal cation diffusivity of the ceramic ion-selective membrane. When a defect occurs through the ceramic ion-selective membrane, metal cation transport will be enhanced by orders of magnitude towards and into the defect, driven by the chemical or electrical potential difference between the two sides of the membrane.Type: ApplicationFiled: March 15, 2017Publication date: August 15, 2019Applicant: UNIVERSITETET I OSLOInventors: Truls Eivind NORBY, Yngve LARRING, Ragnhild HANCKE, Zuoan LI, Wen XING, Marie-Laure FONTAINE, Tor GRANDE, Mtabazi Geofrey SAHINI

Patent number: 5518970Abstract: The present invention relates generally to a novel and unique class of gly materials and methods of making such materials in which substantially all of the anions are nitride ions, in contrast to the oxide ions of conventional optical glasses, or the fluoride ions of the more recently discovered fluoride optical glasses. The chemical nature of these new glasses dispose the glassy materials to a remarkable combination of desirable properties, including, but not limited to, high hardness, high refractive index and high softening temperature.Type: GrantFiled: May 24, 1995Date of Patent: May 21, 1996Assignee: Arizona Board of Regents acting on behalf of Arizona State UniversityInventors: Paul F. McMillan, C. Austen Angell, Tor Grande, John R. Holloway
