Patent number: 11920035Abstract: This disclosure concerns electrically conducting poly(pyrazoles). The concept of oligomerizing and polymerizing substituted aminopyrazole derivatives combined with a monomer activation procedure involving base-mediated conversion of the protonated pyrazole ring nitrogen to amine salt was developed. This disclosure concerns the specific chemistries needed for the synthesis of a pyrazole monomer used in the polymer synthesis. The procedure used for blending the novel polypyrazoles with other compounds needed for construction of solar cells for testing was developed. This disclosure concerns the concept of using these types of heteroatom-rich, electron-deficient oligomers or polymers as n-dopable or p-dopable electron acceptors in photovoltaic cells. This disclosure concerns synthesizing the starting monomer compounds and polypyrazoles.Type: GrantFiled: October 25, 2022Date of Patent: March 5, 2024Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Brett D. Martin, Ian D. Giles, Jawad Naciri, Paul T. Charles, Scott A. Trammell, Jeffrey R. Deschamps, Jeffrey C. Depriest

Publication number: 20140273062Abstract: Described herein is a sealed cell pack with a permeable membrane for growth and manipulation of three-dimensional cell cultures. This allows a cell culture to be removed from the laboratory and subjected to real world insults before being returned to culture conditions for continued growth and study. One application is for use in the study of the direct effects of blast waves on neuronal cells and methods for mitigating this response.Type: ApplicationFiled: March 5, 2014Publication date: September 18, 2014Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Thomas O'Shaughnessy, Paul T.

Patent number: 7785769Abstract: The use of sugar-containing hydrogels as very highly porous, aqueous support material for the immobilization of oligonucleotides, peptides, proteins, antigens, antibodies, polysaccharides, and other biomolecules for sensor applications. Unusually large sizes of interconnected pores allow large target molecules to pass rapidly into and through the gel and bind to immobilized biomolecules. Sugar-containing hydrogels have extremely low non-specific absorption of labeled target molecules, providing low background levels. Some hydrogel materials do not have this type of homogeneous interconnected macroporosity, thus large target molecules cannot readily diffuse through them. Additionally, they nearly always experience non-specific absorption of labeled target molecules, limiting their usefulness in sensor applications. A method is provided for preparing sugar polyacrylate hydrogels with functional chemical groups which covalently bond oligonucleotides and peptides.Type: GrantFiled: July 25, 2003Date of Patent: August 31, 2010Assignee: The United States of America as reprsented by the Secretary of the NavyInventors: Mark S. Spector, David A. Stenger, Charles H. Patterson, Jr., Brett D. Martin, Paul T. Charles

Patent number: 7749438Abstract: Periodic mesoporous organosilicas (PMO) which incorporate an optically active molecule into the material for use as an optical indicator of target binding. This material combines the stability, selectivity, and high density of binding sites characteristic of the PMO with the sensitivity and selectivity of the optically active molecule. The material undergoes a change when exposed to a sample containing a target molecule. The change can be observed by visual inspection or through the use of fluorescence spectra.Type: GrantFiled: August 17, 2006Date of Patent: July 6, 2010Assignee: The United States of America as represented by the Secretary of the NavyInventors: Mazyar Zeinali, Brandy J White, Paul T Charles, Michael A Markowitz
