Figs 24–27 in On the Nature of Tintinnid Loricae (Ciliophora: Spirotricha: Tintinnina): a Histochemical, Enzymatic, EDX, and High-resolution TEM Study
Figs 24–27. Transmission electron micrographs of a lorica surface in Eutintinnus angustatus at middle (24) and higher (25–27) resolution. 24 – crystal lattice; 25 – digitally enlarged detail of Fig. 24 (bottom part). The periodicity of the hexagonal structures amounts to ~ 23.7 nm with a resolution of ~ 3 nm for the smallest details; 26 – fast Fourier transform of Fig. 25; 27 – noise filtered bright field image after inverse Fourier transform of Fig. 26, using only the diffraction spots. Due to the enhanced contrast, the ultrastructure of the crystal lattice appears more distinct.
Figs 20–23 in On the Nature of Tintinnid Loricae (Ciliophora: Spirotricha: Tintinnina): a Histochemical, Enzymatic, EDX, and High-resolution TEM Study
Figs 20–23. Transmission electron micrographs of a lorica surface in Eutintinnus angustatus at middle resolution. 20 – a crystalline region ~ 1.5 µm in diameter is shown in the centre of the micrograph. An aggregate of bitter salt (MgSO 4) is attached to the wall (arrow); 21 – crystalline area at higher magnification showing dark spots of sodium and potassium chloride on the lorica wall; 22 – each black spot represents a NaCl or KCl nanocrystal (arrows), which has almost the same size as the unit cells of the crystal lattice (~ 20 nm); 23 – Fourier filtered high-resolution micrograph of a sodium chloride nanocrystal.
Fig. 15. Energy-dispersive X in On the Nature of Tintinnid Loricae (Ciliophora: Spirotricha: Tintinnina): a Histochemical, Enzymatic, EDX, and High-resolution TEM Study
Fig. 15. Energy-dispersive X-ray spectrometric (EDX) analysis in the scanning electron microscope, using uncoated material. The analysed area of the Eutintinnus angustatus lorica is marked by a white frame (~ 11 × 9 µm in size). Since this part of the lorica was freely suspended in the vacuum, elemental detection occurred without influence of the carbon substrate.
Figs 16–19 in On the Nature of Tintinnid Loricae (Ciliophora: Spirotricha: Tintinnina): a Histochemical, Enzymatic, EDX, and High-resolution TEM Study
Figs 16–19. Transmission electron micrographs of an uncoated lorica surface of Eutintinnus angustatus at different magnifications. 16 – overview of right lorica half. The lorica lies nearly horizontally on the electron transparent holey carbon substrate. The black rectangular structures are the copper bars of the TEM grid; 17 – anterior portion of right lorica half; 18 – apical lorica portion; 19 – lateral lorica portion. The dark crystalline dendritic structures consist of sodium chloride nanocrystals, which probably originate in the sea water.

Raman spectra and SEM EDX analyses of artifacts resembling Ediacaran / Cambrian fossils
<p>This data is related to the paper: "Artifacts resembling Ediacaran / Cambrian fossils: how to identify them and avoid their generation" submitted for publication in the "Journal of Micropaleontology" on March 24, 2023.</p> <p>The reaction between hydrogen peroxide and pyrite can lead to the generation of objects very similar to Ediacaran and Cambrian fossils, such as <em>Cloudina</em>. This dataset and related paper provides criteria to distinguish artifacts from fossils based on their composition and structure. This dataset cotains all the Raman spectra and SEM/EDX analyses of artifacts that characterize them and are used for discussion in the related paper.</p>

Animations and raw data to illustrate the location and registration quality of SEM + EDX + laser ablation datasets
<p>Video animations of the three mapping areas discussed in the (yet unpublished) paper "<em>LA-ICP-MS and SEM-EDX for spatially resolved major minor and trace element detection in cement clinker phases</em>" and its supplementary document.</p> <p>This dataset is based on scanning electron microscopy (SEM) in combination with energy dispersive X-ray spectrometry (EDX) and aser ablation in combination with inductively coupled plasma mass spectrometry (LA-ICP-MS). The animations illustrate the exact position of the SEM-EDX mapping and the LA-ICP-MS mapping. Additionally all available SEM images (Backscatter electron (BSE) and secondary electron (SE) images) and their location are visualized.</p> <p>The SEM images of area 1 and area 2 were acquired using a high-resolution dual beam SEM (Helios G4 UX, ThermoFischer Scientific), equipped with a silicon drift EDX detector (XMAX 80, Oxford Instruments, UK). Area 3 was examined using a high-resolution SEM (NanoSEM, FEI) with another EDX-detector (EDAX/AMETEK Octane Elect Plus). </p> <p>Laser ablation was done with a ns-Nd:YAG-laser (ESI NWR 213 Nd:YAG) at the quintupled wavelength of 213 nm. The laser spot size was set to 6 µm x 6 µm.</p> <p>The dataset contains the the video files (animation area <strong>x</strong>.mp4), the images and the Kdenlive file to generate the video files (raw_area <strong>x</strong>_animation.zip) and the raw SEM images (raw_area <strong>x</strong>_<strong>y</strong>.tif) as acquired and in some cases an edited version (raw_area <strong>x</strong>_<strong>y_</strong>touchup.tif).</p> <p><strong>x</strong> = area number</p> <p><strong>y</strong> = image descripton</p>
Fig. 28 in On the Nature of Tintinnid Loricae (Ciliophora: Spirotricha: Tintinnina): a Histochemical, Enzymatic, EDX, and High-resolution TEM Study
Fig. 28. Scheme of the crystal structure in a lorica surface in Eutintinnus angustatus. The primitive unit cell of the crystal is rhombohedral, while three of them form a hexagonal pattern (see white lines). In the simplified model of the crystal structure, the basic units consist of triangles with a diameter of ~ 18 nm, which are interconnected on each side by channels with a diameter of ~ 7 nm. The empty space between the triangles and channels appear as dark areas, having the shape of a cloverleaf, and are ~ 7 nm long. The rim of the triangle and the interconnecting channels visible as bright lines in the image consists of a protein wall, which is ~ 2.5 nm thick. Within the triangles no clear or regular structures could be observed.
