Crystallographic order and decomposition of [MnIII6CrIII]3+ single-molecule magnets deposited in submonolayers and monolayers on HOPG studied by means of molecular resolved Atomic Force Microscopy (AFM) and Kelvin Probe Force Microscopy in UHV

Gryzia A, Volkmann T, Brechling A, et al. Crystallographic order and decomposition of [MnIII6CrIII]3+ single-molecule magnets deposited in submonolayers and monolayers on HOPG studied by means of molecular resolved Atomic Force Microscopy (AFM) and Kelvin Probe Force Microscopy in UHV. Nanoscale Research Letters. 2014;9(1): 60.Monolayers and submonolayers of [MnIII6CrIII]3+ single-molecule magnets (SMMs) adsorbed on highly oriented pyrolytic graphite (HOPG) using the droplet technique characterized by non-contact atomic force microscopy (nc-AFM) as well as by Kelvin probe force microscopy (KPFM) show island-like structures with heights resembling the height of the molecule. Furthermore, islands were found which revealed ordered 1D as well as 2D structures with periods close to the width of the SMMs. Along this, islands which show half the heights of intact SMMs were observed which are evidences for a decomposing process of the molecules during the preparation. Finally, models for the structure of the ordered SMM adsorbates are proposed to explain the observations

Structural organization of DMPC lipid layers on chemically micropatterned self-assembled monolayers as biomimetic systems

Brechling A, Pohl M, Kleineberg U, Heinzmann U. Structural organization of DMPC lipid layers on chemically micropatterned self-assembled monolayers as biomimetic systems. JOURNAL OF BIOTECHNOLOGY. 2004;112(1-2):115-125.The growth structure of DMPC lipid layers on hydrophobic and hydrophilic alkylsilane-based self-assembled monolayers adsorbed on silicon has been investigated by means of X-ray reflectometry and atomic force microscopy. Hydrophilic modification of hydrophobically terminated ODS-SAMs has been achieved by dose-controlled irradiation with DUV light. While island formation of small DMPC bilayer islands is observed on hydrophobic SAM surfaces, closed layers of DMPC monolayers are formed on hydrophilic SAM surfaces. Furthermore, DMPC adsorption on chemically micropatterned substrates with alternating hydrophobic/hydrophilic surface properties has been studied by imaging ellipsometry and photoemission microscopy. Indication for at least partial bridging of hydrophobic areas by an adsorbed DMPC monolayer has been found. (C) 2004 Elsevier B.V. All rights reserved

Characterization and tests of planar Co3O4 model catalysts prepared by chemical vapor deposition

Bahlawane N, Fischer Rivera E, Kohse-Höinghaus K, Brechling A, Kleineberg U. Characterization and tests of planar Co3O4 model catalysts prepared by chemical vapor deposition. Applied Catalysis B - Environmental. 2004;53(4):245-255.The chemical vapor deposition method was used to deposit thin films of cobalt oxide starting with cobalt (II) acetylacetonate and oxygen. The deposition process was investigated and the obtained films were identified as a cubic spinel-type polycrystalline Co3O4 with a crystallite size of 30-40 nm. The coating was carbon-free and the Surface oxygen concentration was measured to be 66 at.% with AES analysis. Smooth and highly uniform thin films were deposited on planar stainless steel substrates and subjected to TPR and catalysis tests that show positive correlation. The apparent activation energy Of Co3O4 reduction to COO was measured to be (33 +/- 5) kJ/mol. The catalytic activity of Co3O4 was investigated toward the conversion of both propane and ethanol to carbon dioxide. Though the catalytic action was registered at the same temperature. the deactivation process was seen to be different. The catalytic conversion of ethanol induces a fast deactivation process, which was linked to its high ability to reduce Co3O4. (C) 2004 Elsevier B.V. All rights reserved
