Patent number: 8956538Abstract: Disclosed herein are systems and methods for desalination of salt water based on an engineered acoustic field that causes constructive and destructive interference at pre-computed spatial positions. The engineered acoustic field can cause high-pressure and low-pressure regions where desalination membranes are located. The induced pressure from the acoustic field can force pure water through the membranes leaving ionic and dissolved molecular species behind.Type: GrantFiled: June 16, 2011Date of Patent: February 17, 2015Assignee: FloDesign Sonics, Inc.Inventors: Edward A. Rietman, Bart Lipkens

Patent number: 8945391Abstract: The object of the invention is to provide an organic polymers-separation membrane filter capable of physically separating organic polymers based on their molecular stereostructure difference without giving rise to chemical changes in them and without selecting their chemical compositions. The organic polymers-separation membrane filter comprising an ultrafilter membrane is characterized in that a path taken by a nano permeation pore has a narrower path portion having a width narrower than that of the rest, wherein organic polymers capable of changing in their stereostructure are passed through the path while their width is transformed into a configuration along the narrower path portion, thereby separating the organic polymers. In the ultrafilter membrane, particulate materials are mutually coupled together in its thickness and planar directions. The particulate materials comprise a protein.Type: GrantFiled: April 26, 2010Date of Patent: February 3, 2015Assignee: National Institute for Materials ScienceInventors: Izumi Ichinose, XinSheng Peng
