Patent number: 11814563Abstract: The disclosure discusses chiral dopants for liquid-crystalline materials. Chiral dopants can be bioreachable compounds, i.e. compounds produced from microbes through fermentation. Chiral dopants can also include bioreachable materials that are further modified by chemical synthetic steps. Chiral dopants as discussed herein can include biomolecules such as glycyrrhetinic acid (1), S-naringenin (2), shikimic acid (3), alpha-phellandrene (4), betulin (5), malic acid (6), valencene (7), or nootkatone (8), and any stereoisomers or chemically modified derivatives thereof. The disclosure further shows optical properties of such compounds in a liquid-crystalline material.Type: GrantFiled: December 6, 2019Date of Patent: November 14, 2023Assignees: Zymergen Inc., Kent State UniversityInventors: Adam Safir, Shilpa Naresh Raja, Arjan Zoombelt, Robert J.

Publication number: 20230279182Abstract: The present disclosure describes methods of polyimide synthesis and polyimides made therefore. The method includes placing a tetracarboxylic compound and a solvent in a reaction vessel and adding a first amount of a diamine. The first amount of the diamine is not more than 99.5 mol % of the tetracarboxylic compound inside the reaction vessel. The method can include agitating the mixture and determining a viscosity of the mixture. The method can further include adding a second amount of the diamine. The last steps can be repeated until the viscosity increases to a target value. The target viscosity can be correlated to a peak weight-averaged molecular weight of the polyimide.Type: ApplicationFiled: October 5, 2020Publication date: September 7, 2023Inventors: Justin KERSZULIS, Abhiram KANNAN, Peter Lucas POLIAK, Liza LOPEZ, Kelby HULL, Patrick HOMYAK, Gaurav CHACHRA, Christopher Leland MCGANN, Arjan ZOOMBELT, Koji ISHIWATA
