Patent number: 11964885Abstract: Tandem electrodialysis (ED) cell systems and methods for using the tandem ED cell systems to extract and recover ions from ion-containing solutions are provided. The tandem ED cell systems are composed of ion-extraction and ion-recovery ED cells. A redox couple contained in the anolyte of the ion-extraction ED cell is different from a redox couple contained in the catholyte of the ion-extraction ED cell. The electrode reactions in the ion-extraction ED cell are reversed in the ion-recovery ED cell, with the anolyte and catholyte of the two ED cells swapped and continuously circulated. As a result, the redox species in the anolyte and catholyte of the two cells are never depleted, which allows for achieving ion extraction and ion recovery with the use of a minimal amount of the redox couples.Type: GrantFiled: February 10, 2021Date of Patent: April 23, 2024Assignee: Wisconsin Alumni Research FoundationInventors: Kyoung-Shin Choi, Dohwan Nam

Patent number: 11957828Abstract: Blood is conveyed from a source into a separator, which separates at least one target blood component from the blood. The target blood component is then conveyed out of the separator, with the procedure continuing until an initial target amount of blood to be processed has been conveyed from the source into the separator and the target blood component separated from the initial target amount of blood to be processed has been conveyed out of the separator as an actual yield of the target blood component. An adjusted target amount of blood to be processed is then determined based at least in part on the difference between a target yield of the target blood component and the actual yield. The initial target amount of blood to be processed is then replaced with the adjusted target amount of blood to be processed when next executing the procedure.Type: GrantFiled: September 14, 2020Date of Patent: April 16, 2024Assignee: Fenwal, Inc.Inventor: Brian C.

Patent number: 11938423Abstract: The present invention provides a system and methods for filtering fluid using filter papers, stationary paper, cloth sheets or any other porous material. In one embodiment, the present invention uses the lateral flow direction along the porous sheets, instead of conventional vertical flow direction, for the removal of bacteria and particle contamination in the range from nanometers to millimeters. The pore sizes in the filter media along the lateral direction are modulated by controlling the compression of the porous sheets, instead of conventionally designing filters with different pore sizes. The lateral flow fluid filter system is scalable simply by increasing the feed area, feed length, and the number of porous sheets. The invention presents a universal fluid filtration system for wide range of applications such as water purification, food processing, chemical industry, oil and gas industry, and biological applications.Type: GrantFiled: October 15, 2021Date of Patent: March 26, 2024Assignee: NEW YORK UNIVERSITY IN ABU DHABI CORPORATIONInventors: Sunil Kumar, Nityanand Kumawat, Mohammad A.

Patent number: 11918936Abstract: The present disclosure discusses a method of separating a sample including oligonucleotides including coating a flow path of a chromatographic system; injecting the sample comprising oligonucleotides into the chromatographic system; flowing the sample through the chromatographic system; and separating the oligonucleotides. In some examples, the coating of the flow path is non-binding with respect to the analyte, such as oligonucleotides. Consequently, the analyte does not bind to the coating of the flow path. The non-binding coating eliminates the need for passivation, which can eliminate the formerly needed time to passivate as well. In addition, analyte can be recovered with a first injection in a system, such as chromatographic system.Type: GrantFiled: January 15, 2021Date of Patent: March 5, 2024Assignee: Waters Technologies CorporationInventors: Michael Donegan, Martin Gilar, Armand Gatien Ngounou Wetie
