Patent number: 11859164Abstract: Scalable biomaterial-based bioreactors are described. In one embodiment, the bioreactor may comprise perforated plates stacked such that the assembled bioreactor has the necessary manifolds and chambers to transport gas and liquids to a biomaterial contained within the bioreactor, and to remove the reaction products. In another embodiment, single use bioreactors are described. Methods of operating the bioreactors are also described.Type: GrantFiled: April 14, 2021Date of Patent: January 2, 2024Assignee: Battelle Memorial InstituteInventors: Zia Abdullah, Michael L.

Patent number: 10982101Abstract: A method of making CNT films is described in which the film is washed with a mild acid treatment. The method generates a CNT film that is not sensitive to moisture or fluctuations in moisture. The method involves the use of anionic polysaccharides or anionic glycosaminoglycans such as hyaluronic acid, sodium salt, as aqueous dispersing agents and their modification to a hydrophobic matrix after deposition. In the course of conducting the work described here, we made the surprising discovery that washing with an aqueous acidic solution resulted in a decrease in resistance through the material. The invention also includes CNT composites made by the inventive methods and a CNT composite comprising CNTs and anionic polysaccharides or anionic glycosaminoglycans further characterized by a low cationic content and a high conductivity and/or small CNT particle size as measured by SEM.Type: GrantFiled: January 21, 2020Date of Patent: April 20, 2021Assignee: Battelle Memorial InstituteInventors: Amy M. Heintz, Chad M. Cucksey, Anthony D. Duong, Randy L. Jones, Michael D. Crenshaw
