Anisotropic mechanical and functional properties of graphene-based alumina matrix nanocomposites
Çelik, Yasemin; Çelik, A.; Flahaut, Emmanuel; Suvacı, Ender (Elsevier Sci LTD, 2016)Graphene platelets (GPLs) containing Al2O3 nanocomposites, which exhibit anisotropic microstructure, have been prepared by spark plasma sintering (SPS), and effects of this anisotropy on mechanical, electrical and thermal ... -
Application of Homogeneously Precipitated Nanosized Fe-Doped Alumina Powders to Carbon Nanotube Growth
Çelik, Yasemin; Suvacı, Ender; Flahaut, Emmanuel; Weibel, Alicia; Peigney, Alain (Wiley, 2010)Homogeneous precipitation of hydroxides was investigated as an alternative method to synthesize Fe-doped aluminum oxide (alpha-Al2-2xFe2xO3) particles over which carbon nanotubes (CNTs) were grown via a catalytic chemical ... -
A comparative study on few-layer graphene production by exfoliation of different starting materials in a low boiling point solvent
Çelik, Yasemin; Flahaut, Emmanuel; Suvacı, Ender (Elsevier Science BV, 2017)Three different graphite-based powders (expandable graphite and two different nano-graphite powders) were investigated as starting materials for an effective liquid phase exfoliation process in isopropyl alcohol (IPA). The ... -
Organized growth of carbon nanotubes on Fe-doped alumina ceramic substrates
Suvacı, Ender; Çelik, Yasemin; Weibel, Alicia; Peigney, Alain; Flahaut, Emmanuel (Pergamon-Elsevier Science LTD, 2012)Polycrystalline Fe-doped alumina (Al2O3) ceramics have been produced and used as a substrate for organized carbon nanotubes (CNTs) growth by catalytic chemical vapor deposition (CCVD). In these substrates, Fe3+ cations, ... -
Production of graphene based materials and their potential applications
Çelik, Yasemin (Anadolu Üniversitesi, 2015)Grafen benzersiz özellikleri sayesinde pek çok uygulama alanı için umut vadeden bir malzemedir. Bununla birlikte, grafen-esaslı malzemelerin özellikleri ve miktarı hangi üretim yöntemi ile üretildiğine bağlı olarak farklılık ... -
Relationship between heating atmosphere and copper foil impurities during graphene growth via low pressure chemical vapor deposition
Çelik, Yasemin; Escoffier, Walter; Yang, Ming; Flahaut, Emmanuel; Suvacı, Ender (Pergamon-Elsevier Science LTD, 2016)Low-pressure chemical vapor deposition synthesis of graphene films on two different Cu foils, with different surface oxygen and carbon contents, was performed by controlling H-2 and/or Ar flow rates during heating. The ... -
Texture development in Fe-doped alumina ceramics via templated grain growth and their application to carbon nanotube growth
Çelik, Yasemin; Suvacı, Ender; Weibel, Alicia; Peigney, Alain; Flahaut, Emmanuel (Elsevier Sci LTD, 2013)Fe-doped alumina (Fe-Al2O3) materials with a controlled microstructure could be designed for some special uses such as a substrate for carbon nanotube growth. In this study, Fe-doped Al2O3 ceramics with varying degrees of ...
