the same system can be used for in-situ nitrogen doping of graphene by introducing nitrogen to the gas-phase precursors. 10:20am TS4-1-10 Soft Carbon Sheets: Synthesis, Processing and Applications in Organic Photovoltaics, J. Huang (jiaxinghuang@northwestern.edu), Northwestern University, US INVITED Graphite oxide sheet, now named as graphene oxide (GO), is the product of chemical exfoliation of graphite that has been known for more than a century. Interest in this old material has resurged with the rapid development of graphene since 2004, as GO is considered to be a promising precursor for bulk production of graphene. However, apart from making graphene, GO itself has many intriguing structural features and properties. For example, it can be viewed as an unconventional type of soft material as it has characteristics of polymers, membranes, colloids, liquid crystals and as highlighted here, amphiphiles. In this talk, some new insights into the processing, characterization and properties of this old material will be presented including (1) a high-throughput, high contrast fluorescence quenching microscopy (FQM) technique that can visualize graphene-based sheets on arbitrary substrates and even in solution; (2) the amphiphilicity of GO and the implications of this “world's thinnest bar of soap” in thin film processing; (3) Making graphene aggregation-resistant by mechanical deformation; and (4) GO based interfacial layer and active layer in solution processed photovoltaic devices. 11:00am TS4-1-12 Growth and characterization of dense CNT Forests on oxide-free copper foil surfaces for charge storage application, G. Atthipalli, K. Strunk, J. Sopcisak, J. Gray (jlg99@pitt.edu), University of Pittsburgh, US We have studied the effect of the native oxide layer on the growth and performance of aligned carbon nanotubes (CNT) on copper substrates tested as double layer capacitors using a “Swagelok” type arrangement. A sputtered Inconel thin film and iron, delivered in vapor phase from ferrocene decomposition during chemical vapor deposition growth of the CNTs both act as catalysts for CNT growth on the copper surface. We analyzed the effectiveness in using this Inconel-Iron “co-catalyst” combination for dense, aligned CNT growth for potential access to greater surface area and subsequent charge storage. SEM, TEM and Raman measurements were made to study the structure and quality of the CNTs under various growth conditions. The results of the characterization show an improvement in density of the CNTs when the copper native oxide layer was removed before Inconel deposition. In addition, these samples also show larger values of power density and specific capacitance. 11:20am TS4-1-13 Growth of organic semiconductor films on graphene, G. Hlawacek, F. Khokhar, R. van Gastel, B. Poelsema, H. Zandvliet, University of Twente, Netherlands, C. Teichert (teichert@unileoben.ac.at), Montanuniversität Leoben, Austria Organic semiconductors offer the possibility to fabricate of low-cost organic light emitting diodes (OLEDs) and solar cells. The novel material graphene bears the potential to be used as transparent flexible electrode in such devices. Thus, the investigation of the growth of organic molecules on graphene is an up-to-date topic. Here, Low Energy Electron Microscopy (LEEM) and micro Low Energy Electron Diffraction (µ-LEED) have been employed to study in situ the initial growth of the organic semiconductor para-sexiphenyl (6P) on Ir(111) supported graphene. For low deposition temperatures, indeed layer-by-layer growth of lying molecules is observed as it is desired for OLEDs [1]. After formation of a low density layer, the full first monolayer already shows a bulk like structure. The nucleation of the graphene islands occurs at wrinkles in the metal supported graphene layer. Larger islands composed of flat lying molecules detach from the original nucleation sites and move rapidly as entities across wrinkle free substrate areas [2]. µLEED reveals the surface unit cells in the different growth stages and at various substrate temperatures.

Naumenko, Forschungszentrum Jülich GmbH, Germany 1:50pm A1-2-1 Microstructure degradation of simple, Pt- and Pt+Pdmodified aluminide coatings on CMSX-4 superalloy under cyclic oxidation conditions, R. Swadzba (rswadzba@gmail.com), Silesian University of Technology, Poland The paper presents results of simple, Pt/Pd- and Pt-modified aluminide coatings cyclic oxidation-induced degradation analysis. The coatings were deposited by Pt and Pt+Pd electroplating, followed by vapor phase aluminizing at 1050˚C. Cyclic oxidation tests were performed at 1100˚C in 23h cycles. Microstructural and phase analysis conducted using SEM, EDS and EBSD methods revealed that the oxide layers that formed on the coatings were composed of three distinctive types of oxides growing according to a specific pattern which is described. The oxide layer that formed on the simple aluminide coating exhibited low adhesion in comparison to Pt- and Pt,Pd-modified aluminide coatings which managed to maintain an adherent oxide layer that contained higher amount of desirable α-alumina. The Al-depleted βNiAl grains remained much larger in the modified aluminide coatings, even after failure. What is more, stripes characteristic for martensitic transformation were discovered in the β phase grains in all coatings. Based on the results a microstructural degradation scheme of the investigated coatings is presented. 2:10pm A1-2-2 Influence of vacuum parameters during heat treatment on surface composition of MCrAlY coatings, I. Keller (i.keller@fzjuelich.de), D. Naumenko, L. Singheiser, W.J. Quadakkers, Forschungszentrum Jülich GmbH, Germany MCrAlY type (M = Ni, Co) coatings are commonly used as overlay coatings and bond coats (BC`s) for thermal barrier coatings (TBC`s) in aero engines and industrial gas turbines. It is known that the life time of thermal barrier coatings is crucially affected by the properties of the thermally grown oxide (TGO), which is formed during high temperature service at the TBC/BC interface. The most relevant properties of the oxide scale are growth rate, adherence to the BC, and composition [1]. Several investigations have shown that the TGO-properties depend strongly on the parameters of vacuum heat treatment commonly applied to the MCrAlY coated components prior to TBC deposition [2-4]. Variation of the heat treatment parameters can result in formation of different types of oxide scales on BC`s with nominally the same composition, which leads to different lifetimes of the TBC. In the present study the influence of vacuum parameters and atmosphere composition on the phase equilibrium at the MCrAlY surfaces during heat treatment are investigated. For this purpose free standing MCrAlY coatings (manufactured via VPS or HVOF) with rough and polished surfaces were exposed at 1100 °C for times between 1 and 5 hours in different atmospheres (
