Patent number: 7981268Abstract: The present invention provides a new method and apparatus/system for purifying ionic solutions, such as, for example, desalinating water, using engineered charged surfaces to sorb ions from such solutions. Surface charge is applied externally, and is synchronized with oscillatory fluid movements between substantially parallel charged plates. Ions are held in place during fluid movement in one direction (because they are held in the electrical double layer), and released for transport during fluid movement in the opposite direction by removing the applied electric field. In this way the ions, such as salt, are “ratcheted” across the charged surface from the feed side to the concentrate side. The process itself is very simple and involves only pumps, charged surfaces, and manifolds for fluid collection.Type: GrantFiled: January 19, 2007Date of Patent: July 19, 2011Assignee: Lawrence Livermore National Security, LLCInventors: William L. Bourcier, Roger D. Aines, Jeffery J. Haslam, Charlene M. Schaldach, Kevin C. O'Brien, Edward Cussler

Patent number: 7972818Abstract: Disclosed herein are two methods for rapid multiplex analysis to determine the presence and identity of target DNA sequences within a DNA sample. Both methods use reporting DNA sequences, e.g., modified conventional Taqman® probes, to combine multiplex PCR amplification with microsphere-based hybridization using flow cytometry means of detection. Real-time PCR detection can also be incorporated. The first method uses a cyanine dye, such as, Cy3™, as the reporter linked to the 5? end of a reporting DNA sequence. The second method positions a reporter dye, e.g., FAM™ on the 3? end of the reporting DNA sequence and a quencher dye, e.g., TAMRA™, on the 5? end.Type: GrantFiled: June 16, 2006Date of Patent: July 5, 2011Assignee: Lawrence Livermore National Security, LLCInventors: Shanavaz Nasarabadi, Richard G.
