Publication number: 20150298421Abstract: The invention provides composite components, structures and method for producing composite components. A composite component has a negative effect Poisson's ratio and comprises a first component and a second component. The first component and the second component extend longitudinally relative to an axis, the first component being provided around the second component through one or more turns which are spaced longitudinally relative to the axis. A variation in the tensile load on the first component causes the radial position of the second component relative to the axis to vary.Type: ApplicationFiled: October 24, 2014Publication date: October 22, 2015Inventors: Patrick Barry Hook, Kenneth E. Evans, Jonathan Paul Hannington, Claire Hartmann-Thompson, Timothy Rex Bunce

Patent number: 7998415Abstract: A chemical sensor having a transducer element and a layer of composite material including a polymer matrix and a solid particulate filler disposed in the polymer matrix provides chemical sensors exhibiting improved properties. In particular, the device allows polymer matrix materials to be selected based primarily on diffusion properties, strength, stability and other physical characteristics substantially independent of limitations and compromises that arise when attempting to synthesize polymers having specific types of sensory groups chemically bound to the polymer. The invention also allows greater ability to modify sensor response characteristics by appropriate modification of the particulate filler, whereby a diverse sensor array may be fabricated more easily and at a lower cost.Type: GrantFiled: May 15, 2009Date of Patent: August 16, 2011Assignee: Michigan Molecular InstituteInventor: Claire Hartmann-Thompson

Publication number: 20100104918Abstract: This invention concerns an improved PEM for fuel cell applications such that the membrane is more robust. Specifically, this invention provides PEM in MEA systems that have nano-particles carrying proton conducting groups, and improved dimensional stability relative to conductivity. This invention provides a composition of matter for a high proton conductance, solid polymer electrolyte membrane, said membrane comprising: A) a nano-additive carrying proton conducting groups having a size from about 1 nm to about 1,000 run; B) a carrier polymer for the nano-additive of Part A; and C) a proton exchange membrane (PEM) or membrane electrode assembly (MEA) formed by mixing the components of Part A and Part B above. These proton conducting groups are contributed by POSS-based nano-additives or cyclic phosphazene-based nano-additives or small molecules carrying sulfonic acid groups in fuel cells or batteries.Type: ApplicationFiled: April 11, 2008Publication date: April 29, 2010Applicant: Michigan Molecular InstituteInventors: Robert M.

Publication number: 20100019169Abstract: This invention concerns the remote detection of threat clouds and evaluation of their components. Also included is the remote detection and evaluation of contamination on surfaces or in air streams. To enable this detection, fluorophores that are attached to POSS are used with two-photon LIF imaging that provides enhanced background-free imaging even in the presence of scattering particles such as dust, sand and water droplets.Type: ApplicationFiled: January 25, 2008Publication date: January 28, 2010Applicant: Michigan Molecular InstituteInventor: Claire Hartmann-Thompson
