Patent number: 9782744Abstract: Composite films comprising an organic salt (or GUMBOS) such as 1-n-butyl-2,3-dimethylimidazolium hexafluorophosphate and a polymer such as cellulose acetate are prepared. These films are useful in detecting vapors of volatile organic compounds, and in determining their molecular weights. A quartz crystal microbalance-based sensor was designed by depositing a thin film of this composite material on the gold electrode surface of a quartz crystal resonator. The sensor exhibited rapid response toward a variety of volatile organic compounds, and complete regeneration, high sensitivity, low detection limits, and wide dynamic ranges. The ratio of the change in frequency to the change in motional resistance is a concentration-independent quantity that is proportional to the molecular weight of the absorbed chemical species. These properties facilitate the easy identification and molecular weight determination of a broad range of organic vapors.Type: GrantFiled: January 19, 2012Date of Patent: October 10, 2017Assignee: Board of Supervisors of Louisiana State University And Agricultural and Mechanical CollegeInventors: Isiah M.

Patent number: 7427526Abstract: This invention uses large surface to volume ratio materials for separation, release layer, and sacrificial material applications. The invention outlines the material concept, application designs, and fabrication methodologies. The invention is demonstrated using deposited column/void network materials as examples of large surface to volume ratio materials. In a number of the specific applications discussed, it is shown that it is advantageous to create structures on a laminate on a mother substrate and then, using the separation layer material approach, to separate this laminate from the mother substrate using the present separation scheme. It is also shown that the present materials have excellent release layer utility. In a number of applications it is also shown how the approach can be used to uniquely form cavities, channels, air-gaps, and related structures in or on various substrates.Type: GrantFiled: April 17, 2001Date of Patent: September 23, 2008Assignee: The Penn State Research FoundationInventors: Stephen J.

Patent number: 7309620Abstract: The invention relates to methods for preparing a removable system on a mother substrate. The method deposits a high surface to volume sacrificial layer on a mother substrate and stabilizes the sacrificial layer by a) removing volatile chemical species in and on the sacrificial layer and/or b) modifying the surface of the layer. The method coats over the sacrificial layer with a capping medium. A system is the fabricated on the capping medium. The method provides through holes to access the sacrificial layer. The method may also apply a top layer onto the system to form a covered system. The invention also includes the step of removing the sacrificial layer to release the system from the mother substrate. Methods of the invention also include selectively removing a portion of the system and capping layers to form void regions defining an array of islands composed of device, structure, or system and capping layer regions, and optionally filling the island-defining void region with a sacrificial material.Type: GrantFiled: January 13, 2003Date of Patent: December 18, 2007Assignee: The Penn State Research FoundationInventors: Stephen J.
