Publication number: 20110223331Abstract: The present invention relates to a mesoporous monolith containing a conducting polymer such as poly(3,4-ethylenedioxythiophene) and methods for making the monolith. The mesoporous monolith is electroactive, at least semi-transparent and has one or more of a large internal pore surface area, pore size and pore volume. It can be used for various applications in photovoltaics, sensing electrochromics, separations, reversible ion exchange and control of protein activity. The method employs hydrothermal treatment and/or substantially complete drying to obtain the desirable properties of the monolith. Conducting polymer can be covalently bound to the internal pore surfaces and polymerized in situ to partially or completely fill the pores producing increased mechanical strength and a high conductivity per unit area.Type: ApplicationFiled: September 17, 2010Publication date: September 15, 2011Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Brett D. Martin, Michael A. Markowitz, Brian Melde

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

Patent number: 6713416Abstract: A method of making a molecularly imprinted porous structure makes use of a surfactant analog of the molecule to be imprinted that has the imprint molecule portion serving as the surfactant headgroup. The surfactant analog is allowed to self-assemble in a mixture to create at least one supramolecular structure having exposed imprint groups. The imprinted porous structure is formed by adding reactive monomers to the mixture and allowing the monomers to polymerize, with the supramolecular structure serving as a template. The resulting solid structure has a shape that is complementary to the shape of the supramolecular structure and has cavities that are the mirror image of the imprint group. Similarly, molecularly imprinted particles may be made by using the surfactant to create a water-in-oil microemulsion wherein the imprint groups are exposed to the water phase.Type: GrantFiled: January 8, 2003Date of Patent: March 30, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Michael A. Markowitz, Paul E. Schoen, Bruce P. Gaber, Banahalli R. Ratna, Paul R. Kust, David C. Turner, Douglas S. Clark, Jonathan S. Dordick

Patent number: 6673246Abstract: This invention pertains to adsorption by an adsorbent of an adsorbate and to regeneration of the loaded adsorbent. The adsorption includes contacting an adsorbent selected from arylene-bridged polysilsesquioxanes and derivatives thereof with an adsorbate selected from aromatics and heterocyclics, particularly monocyclic heterocyclics containing carbon and nitrogen atoms in a 6-member non-aromatic ring, for a period of time sufficient to adsorb all or part of the adsorbate by the adsorbent. Regeneration of the loaded adsorbent includes removing all or part of adsorbate from the adsorbent by means of an alcohol wash or by thermal desorption of the adsorbent containing adsorbate.Type: GrantFiled: February 28, 2002Date of Patent: January 6, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Michael A.
