Habitats, abundance patterns and isotopic signals of morphotypes of the planktonic foraminifer Globigerinoides ruber (d'Orbigny) in the eastern Mediterranean Sea since the Marine Isotopic Stage 12
article i nfo The chemical composition of shells of the planktonic foraminifer Globigerinoides ruber (white) is frequently used to determine past sea surface conditions. Recently, it has been shown… Expand
Effects of thermal annealing on the microstructure of sputtered Al2O3 coatings
The morphology and microstructure of Al2O3 thin films deposited by pulsed direct current magnetron sputtering were studied in the as-grown state and after vacuum annealing at 1000 °C for 12 h using… Expand
Formation and mosaicity of coccolith segment calcite of the marine algae Emiliania huxleyi
Coccolithophores belong to the most abundant calcium carbonate mineralizing organisms, and the key to optimizing crystalline biomaterials for mechanical strength and toughness lies in the composite nature of the biological hard tissue and the utilization of specific microstructures. Expand
Nanoprobe crystallographic orientation studies of isolated shield elements of the coccolithophore species Emiliania huxleyi
Coccolithophore algae produce elaborately structured skeletons composed of sub-micrometer-scale calcite crystals. In order to understand calcite crystallization and assembly in a coccosphere with… Expand
TEM preparation methods and influence of radiation damage on the beam sensitive CaCO3 shell of Emiliania huxleyi.
High resolution transmission electron microscopy imaging, electron diffraction and electron energy-loss spectroscopy studies revealed that all prepared samples are relatively stable under electron bombardment at an acceleration voltage of 300 kV when using a parallel illumination. Expand

This work performs in-situ scanning electron microscopy based compression tests and concludes that coccospheres have a mechanical protection function, providing strong evidence for the mechanical protection-hypothesis of coccolithophore calcification. Expand
Electron‐Blocking and Oxygen Evolution Catalyst Layers by Plasma‐Enhanced Atomic Layer Deposition of Nickel Oxide
A plasma-enhanced atomic layer deposition (ALD) process is presented, capable of producing thin conformal films of nickel(II) oxide (NiO) on various substrates. Nickelocene (NiCp2) is used as an… Expand
Mosaic Structure in the Spines of Holopneustes porossisimus
Abstract Sea urchin spines of Holopneustes porossisimus are porous single crystals, with the pores being filled with a material rich in carbon, silicon, fluorine and sodium. The magnesian calcite… Expand
Insight into the core–shell structures of Cu–In–S microspheres
Abstract In this study we report about the inner and outer structure of CuInS2 microspheres which might be used e.g. in pastes for simple, low-cost solar cell preparation, as well as in electrodes… Expand
