1. Nanoscale Specific Heat Capacity Measurements Using Optoelectronic Bilayer Microcantilevers
Topic: Advanced Materials
Published: 12/12/2012
Authors: Brian Gregory Burke, William A Osborn, Richard Swift Gates, David A LaVan
Abstract: We describe a new technique for optically and electrically detecting and heating bilayer microcantilevers (Pt−SiNx) to high temperatures at fast heating rates for nanoscale specific heat capacity measurements. The bilayer microcantilever acts s ...

2. An automated spin-assisted approach for molecular layer-by-layer assembly of crosslinked polymer thin films
Topic: Advanced Materials
Published: 11/28/2012
Authors: Edwin P Chan, Jung-Hyun Lee, Jun-Young Chung, Christopher M Stafford
Abstract: We present the design of an automated spin-coater that facilitates fabrication of polymer films based on molecular layer-by-layer (mLbL) assembly. Specifically, we demonstrate the synthesis of ultrathin crosslinked fully-aromatic polyamide films ...

3. Giant piezoelectricity in PMN-PT thin films: Beyond PZT
Topic: Advanced Materials
Published: 11/1/2012
Authors: S. H. Baek, M. S. Rzchowski, Vladimir A Aksyuk
Abstract: Micro-electromechanical systems (MEMS) incorporating piezoelectric layers provide active transduction between electrical and mechanical energy, which enables highly sensitive sensors and low-voltage driven actuators surpassing the passive operation o ...

4. Anisotropic, Hierarchical Surface Patterns via Surface Wrinkling of Nanoimprinted Polymer Films
Topic: Advanced Materials
Published: 10/22/2012
Authors: Junghyun Lee, Hyun Wook Ro, Rui Huang, Thomas Avery Germer, Paul Lemaillet, Christopher L Soles, Christopher M Stafford
Abstract: we demonstrated the wrinkling behavior of nanopatterned PS films, whose wrinkle wavelength and resultant morphology depend strongly on geometric parameters of surface patterns as well as the direction of the applied strain relative to the nanopattern ...

5. Controlling Thermochromism in a Photonic Block Copolymer Gel
Topic: Advanced Materials
Published: 9/26/2012
Authors: Joseph J Walish, Yin Fan , Andrea Centrone, Edwin L. Thomas
Abstract: Controlling the color via temperature-induced changes of self-assembled photonic materials is important for their application in sensors and displays. The thermochromic behavior of a PS-P2VP photonic gel was studied (UV-VIS, FTIR) and found to origin ...

6. Nucleation products of ligated nanoclusters unaffected by temperature and reducing agent
Topic: Advanced Materials
Published: 8/27/2012
Authors: John M. Pettibone, Nicole R Reardon
Abstract: Atomically uniform nucleation products of ligated metal nanoclusters are observed irrespective of reduction conditions for metal-bidentate ligand systems. Monodentate ligands are not reported to wield similar control, indicating steric contributions ...

7. INVESTIGATING THE MECHANISM OF ENZYME-CATALYZED RING-OPENING COPOLYMERIZATIONS
Topic: Advanced Materials
Published: 8/19/2012
Authors: Matthew T. (Matthew) Hunley, Fahriye Nese Sari, Kathryn L Beers
Abstract: As the research interest in degradable polymers has risen, an ever increasing number of manuscripts report the synthesis of copolymers through ring-opening copolymerization techniques. However, the mechanism of copolymerization remains unexplored. ...

8. Graphene Epitaxial Growth on SiC(0001) for Resistance Standards
Topic: Advanced Materials
Published: 6/1/2012
Authors: Mariano A. Real, Tian T. Shen, George R Jones, Randolph E Elmquist, Johannes A Soons, Albert Davydov
Abstract: Epitaxial growth of graphene layers on 6H-SiC(0001) substrates have been studied in order to improve graphene’s performance for metrological applications. A face-to-face (FTF) sublimation method at 2000 °C and in Ar background atmosphere is used to i ...

9. Optimization of Imaging Polymer Based Scaffolds Using X-Ray Microcomputed Tomography
Topic: Advanced Materials
Published: 5/15/2012
Authors: David E, Morris, Melissa L Mather, Carl GEORGE Simon Jr, John A Crowe
Abstract: The performance of polymer based scaffolds used in regenerative medicine is linked to their structural properties and as such strategies for structural characterization of scaffolds have been developed. X-ray microscopic computed tomography (X-ray ...

10. Gas-Foamed Scaffold Gradients for Combinatorial Screening in 3D
Topic: Advanced Materials
Published: 5/1/2012
Authors: Carl GEORGE Simon Jr, Kaushik Chatterjee, Alison McGibbon Kraigsley, Joachim Kohn, Durgadas Bolikal
Abstract: Current methods for screening cell-material interactions typically utilize two-dimensional (2D) culture format where cells are cultured on flat surfaces. However, there is a need for combinatorial and high-throughput screening methods to systematica ...
