531. Tri-Alpha-Napthyl Benzene as a Crystalline or Glassy Matrix for Matrix-Assisted Laser Desorption/Ionization: A Model System for the Study of Effects of Dispersion of Polymer Samples at a Molecular Level
Topic: Polymers
Published: 1/1/2002
Authors: Barry J. Bauer, Kathleen M. Flynn, Da-Wei Liu, William R. Blair
Abstract: Tri-a-napthyl benzene (TaNB) is used as a matrix in matrix-assisted laser desorption/ionization (MALDI) spectroscopy. Electrosprayed TaNB is crystalline and has a melting point of 180 2 C. After heating above the melting point, TaNB becomes amorp ...

Topic: Polymers
Published: 1/1/2002
Authors: Barry J. Bauer, Charles Martin Guttman, D W. Liu, William R. Blair

533. Tri-a-napthylbenzene as a Glassy or Crystaline Matrix for MALDI TOF MS of Synthetic Polymers
Topic: Polymers
Published: 1/1/2001
Authors: Barry J. Bauer, Charles Martin Guttman, William R. Blair, Da-Wei Liu

534. Tuning Polymer Melt Fragility With Antiplasticizer Additives
Topic: Polymers
Published: 6/19/2007
Authors: Robert A Riggleman, Jack F Douglas, J J de Pablo
Abstract: A polymer-diluent model exhibiting antiplasticization has beendeveloped and characterized by molecular dynamics simulations. Antiplasticizer molecules are shown to decrease the glass transition temperature Tg, but to increase the elastic moduli o ...

535. Ultrafast Dynamics of Gold-Based Nanocomposite Materials
Topic: Polymers
Published: 5/1/2003
Authors: Joseph S Melinger, V D Kleiman, D McMorrow, Franziska Grohn, Barry J. Bauer, Eric J. Amis
Abstract: The ultrafast electron dynamics are investigated for small ((2.5 4.0) nm average diameter) Au nanoparticles contained in two different types of organic-inorganic nanocomposites. In one case, an aqueous solution contains Au nanoparticles embedded in ...

536. Ultrathin Adhesives: Confinement Effect on Modulus
Topic: Polymers
Published: 2/15/2009
Authors: Jessica M. Torres, Christopher M Stafford, Bryan D. Vogt
Abstract: In this work, we will employ this wrinkling metrology to extract the modulus of polymer thin films for a homologous series of poly(n-alkyl methacrylate)s. In particular, we take advantage of the decrease in Tg as the alkyl chain length increases for ...

537. Understanding and Optimizing the MALDI Process Using a Heated Sample Stage: a 2,5-Dihydroxybenzoic Acid Study
Topic: Polymers
Published: 1/1/2004
Authors: Mark Arnould, William E Wallace III, R Knochenmuss
Abstract: Since its use as a compound for matrix assisted laser desorption/ionization (MALDI), 2,5 dihydroxybenzoic acid (DHB) has been the subject of many solid state and gas phase studies. Here, the temperature of DHB during LD experiments was raised from + ...

538. Unusual Multilayered Structures in PEO/Laponite Nanocomposite Films
Topic: Polymers
Published: 11/19/2004
Authors: Avinash Dundigalla, Sheng Lin-Gibson, F Ferreiro, M M Malwitz
Abstract: The unusual structure of poly-ethylene-oxide and Laponite clay in transparentnanocomposite films was investigated using scanning electron, atomic force, optical microscopy, and X-ray scattering. Each method is sensitive to different aspects of struct ...

539. Variation of Electrical Properties With Exfoliation Condition in Nanocomposites
Topic: Polymers
Published: 1/1/2002
Authors: M M McBrearty, Anthony J. Bur, S C Roth
Abstract: Dielectric measurements were made on clay filled nylon and polyethylene-ethyl vinyl acetate (PE-EVA) copolymer nanocomposites during processing by extrusion. Nylon without clay had a small dielectric dispersion while PE-EVA did not. The addition of ...

540. Viscoelastic Property Mapping with Contact Resonance Force Microscopy
Topic: Polymers
Published: 11/4/2011
Authors: Jason Philip Killgore, Donna C. Hurley, Dalia Yablon, Joseph Turner, Philip Yuya, Roger Proksch, Anil Gannepalli, Andy Tsou
Abstract: We demonstrate accurate nanoscale mapping of loss and storage modulus on a polystyrene-polypropylene blend with contact resonance force microscopy (CR-FM). The viscoelastic properties are extracted from spatially resolved maps of the contact resonanc ...
