Patent number: 11914304Abstract: A method to control the density of a three-dimensional photonic crystal template involves changing the irradiation time from at least four laser beams to yield a periodic percolating matrix of mass and voids free of condensed matter from a photoresist composition. The photoresist composition includes a photoinitiator at a concentration where the dose or irradiation is controlled by the irradiation time and is less than the irradiation time that would convert all photoinitiator to initiating species such that the density of the three-dimensional photonic crystal template differs for different irradiation times. A deposition of reflecting or absorbing particles can be patterned on the surface of the photoresist composition to form a template with varying densities above different areas of the substrate.Type: GrantFiled: August 5, 2021Date of Patent: February 27, 2024Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., The Board of Trustees of the University of IllinoisInventors: Shailesh N.

Publication number: 20240026068Abstract: A method of spontaneously patterning a polymer during frontal polymerization includes activating an initiation region of a monomer solution to reaction to initiate a polymerization reaction. A polymerization front is generated and propagates through the monomer solution in a radial or longitudinal direction away from the initiation region. The monomer solution is spontaneously heated downstream of the polymerization front by thermal transport away from the polymerization reaction. Once a localized region of the monomer solution reaches a temperature sufficient for spontaneous initiation of another polymerization reaction, a new polymerization front is generated and propagates through the monomer solution in a circumferential or transverse direction.Type: ApplicationFiled: December 6, 2021Publication date: January 25, 2024Applicant: The Board of Trustees of the University of IllinoisInventors: Jeffrey S.

Patent number: 11869633Abstract: The present disclosure provides methods for accurately predicting the dynamics of symptom response to drugs or other interventions for the treatment of major depressive disorder or other psychological conditions.
