Photoresponse Characteristics of Archetypal Metal-Organic Frameworks (vol 116, pg 3112, 2012)

JOURNAL OF PHYSICAL CHEMISTRY C 2012年第15期116卷 8858-8858页

作者： Feldblyum, Jeremy I. Keenan, Elizabeth A. Matzger, Adam J. Maldonado, Stephen Macromolecular Science and Engineering University of Michigan Ann Arbor MI 48109-2136 2300 Hayward Avenue United States Department of Chemistry University of Michigan Ann Arbor MI 48109-1055 930 North University United States Program in Applied Physics University of Michigan Ann Arbor MI 48109-1040 450 Church Street United States

The photoelectrochemical responses of two archetypal metal–organic frameworks (MOFs), MOF-5 and MOF-177, have been assessed. Films of MOF-5 and MOF-177 were grown on carboxylic-acid-terminated conductive fluorine-doped tin oxide substrates. Separate analyses by powder X-ray diffraction, Raman spectroscopy, and fluorescence spectroscopy collectively indicated these films prepared via a solvothermal method in diethylformamide were free of residual impurities such as ZnO clusters and residual organics. Exposure of these films to white light illumination while immersed in acetonitrile electrolytes elicited measurable photocurrents. Wavelength-dependent analysis of the photoresponses showed that the measured photocurrents were induced by ultraviolet light and that the spectral response profiles followed closely the light absorption profiles of each respective material. Attenuation of the induced photocurrents was noted after prolonged ultraviolet light illumination and/or exposure of the films to H2O(l), indicating that the observed photoresponse properties are directly related to the structural integrity of these MOFs. The cumulative data illustrate that such MOFs have innately light-sensitive properties that are atypical in high surface area materials.

Positronium (Ps) is shown to exist in a delocalized state in self-assembled metalorganic crystals that have large 1.3–1.5 nm cell sizes. Belonging to a class of materials with record high accessible specific surface areas, these highly porous crystals are the first to allow direct probing with simple annihilation lifetime techniques of the transport properties of long-lived triplet Ps in what is hypothesized to be a Bloch state. Delocalized Ps has unprecedented (high) Ps mobility driven primarily by weak phonon scattering with unusual and profound consequences on how Ps probes the lattice.

Structural Relaxations of Thin Polymer Films

Physical Review Letters 2012年第26期108卷 268304-268304页

Time-dependent changes of thermodynamic properties due to structural relaxations and physical aging occur in all glasses. We show that the physical aging of thin supported films of star-shaped macromolecules, with f arms of length Narm, exhibits average aging dynamics that are sensitive to f and Narm. Regions of the films in proximity to interfaces age at substantially different rates than the interior of the film; this is also true of linear chain systems. This behavior may be reconciled in terms of a universal picture that accounts only for changes in the local Tg of the films.

Several approaches have been studied to prepare ionomers for a high temperature proton exchange membrane (PEM) fuel cell. These ionomers were designed to be very low equivalent weight (EW), chemically stable, solvent resistant and highly conductive. The synthetic approaches include grafting, hybrid formation and cross-linking. The most interesting results were obtained from cross-linking of functionalized PFSA ionomers with various cross-linking compounds. New side-chain component multifunctional ionomers have been developed that were cross-linkable during or after membrane fabrication. As a result of this approach, a suite of polymers have been synthesized that, after membrane casting and cross linking show improved solvent resistant, low swelling and excellent proton conductivity. An obvious approach to increase proton conductivity in PSFA materials is to lower the equivalent weight (EW) by increasing the number of protogenic groups. PFSA membranes with EW

The complex interplay of proteins and other molecules, often in the form of large transitory assemblies, are critical to cellular function. Today, X-ray crystallography and electron cryo-microscopy (cryo-EM) are routinely used to image these macromolecular complexes, though often at limited resolutions. Despite the rapidly growing number of macromolecular structures, few tools exist for modeling and annotating structures in the range of 3-10 Å resolution. To address this need, we have developed a number of utilities specifically targeting subnanometer resolution density maps. As part of the 2010 Cryo-EM Modeling Challenge, we demonstrated two of our latest de novo modeling tools, Pathwalking and Gorgon, as well as a tool for secondary structure identification (SSEHunter) and a new rigid-body/flexible fitting tool in Gorgon. In total, we submitted 30 structural models from ten different subnanometer resolution data sets in four of the six challenge categories. Each of our utlities produced accurate structural models and annotations across the various density maps. In the end, the utilities that we present here offer users a robust toolkit for analyzing and modeling protein structure in macromolecular assemblies at non-atomic resolutions. © 2012 Wiley Periodicals, Inc.

Stable dispersions of nanoscale Kevlar fibers with diameters between 3 and 30 nm were obtained by deprotonating macroscale, commercial Kevlar yarns with potassium hydroxide in dimethyl sulfoxide. Those aramid nanofibers were surface-treated with phosphoric acid (PA) and glutaraldehyde (GA), and assembled via layer-by-layer (LBL) and vacuum-assisted filtration method into transversely isotropic films. Through Fourier-transform infrared spectroscopy, transmission-electron microscopy, uniaxial tensile testing and thermo-gravimetric analysis, it was shown that PA hydrolyzes aramid nanofibers which created useful functional groups for surface bonding and GA polymerizes those PA-hydrolyzed nanofibers which served as an inter-fiber crosslinker to improve network properties. A hierarchically structured film made of alternating layers of the high-stiffness, PA/GA-treated, aramid-nanofiber network and high-ductility polyurethane/poly (acrylic acid) was demonstrated to have stiffness and strength exceeding those of commercial Kevlar fiber-woven mats.

Rheological Properties of Silica Filled Poly (Methyl Methacrylate)

引用

MRS Online Proceedings Library 2011年第1期385卷 173-178页

作者： Derek P. Rucker Stacy G. Bike Macromolecular Science and Engineering Program University of Michigan Ann Arbor USA

Ceramic fiber spinning is critical to the manufacture of fibrous monolith ceramics, and understanding the interactions between the polymer matrix and ceramic particle filler is necessary to predict the flow properties of these systems. In this study, poly (methyl methacrylate) (PMMA) was filled with octadecanol-coated St6ber silica, and the rheological behavior of the filled polymers investigated at various filler volume fractions. The rheological behavior of these materials was studied in both dynamic and steady-state experiments. The time required for filled PMMA to reach steady-state behavior under constant shear stress was found to be long, on the order of an hour. The steady-state viscosities increased as expected with filler volume fraction, but did not correlate well with existing models. This is hypothesized to be a result of matrix-filler surface interactions, and will be investigated further in future work.

Nonlinear viscoelasticity of native and engineered ligament and tendon

引用

2010 Annual Conference on Experimental and Applied Mechanics

作者： Jinjin, Ma. Arruda, Ellen M. Department of Mechanical Engineering University of Michigan United States Department of Biomedical Engineering University of Michigan United States Macromolecular Science and Engineering Program University of Michigan United States

Ligaments and tendons are non-linear viscoelastic materials and their response functions are typically assessed using creep and stress relaxation tests. Non-linear viscoelastic models such as multiple Maxwell elements in parallel and the quasilinear viscoelastic model (QLV) used to capture the non-linear viscoelastic response of ligaments and tendons frequently employ multiple relaxation time constants determined from curve-fitting the entire available data set and generally lack a clear physiological relevance. Uniaxial load-unload tension tests on ligament and tendon also manifests the viscoelastic response and such experiments suggest that the bulk of the non-linearity in the response of these soft tissues is in the elasticity. We propose physiologically relevant nonlinear viscoelastic models in which the response of the main structural proteins in ligament and tendon (e.g. collagen and elastin) are described using non-linear elasticity. Our approach using a three-element, non-linear solid micromechanical model captures this viscoelastic response in load-unload, stress relaxation and creep with a limited number of physically meaningful parameters. Previous research also shows different viscoelastic responses between native tendon and ligaments. In our model, by varying the properties of the non-linear springs, we are able to capture the differences in the viscoelastic responses of ligaments verses tendon. We will demonstrate the capabilities of our model by comparing to the experimental results from testing native and engineered ligament and tendon. ©2010 Society for Experimental Mechanics Inc.
