Serial section images of Oikopleura dioica juvenile using SBF-SEM
<p>The larvacean, <i>Oikopleura dioica</i> is a planktonic chordate, which is an emerging model organism with short life cycle of 5 days and belongs to tunicates (urochordates). Organ formation in the trunk proceeds in seven hours form hatching of tailbud larvae at three hours after fertilization (hpf) to completion of organ formation in fully functional juveniles that start feeding at 10 hpf and are just miniature of adult form. The dataset is serial section images of Oikopleura dioica juvenile that were obtained using SBF-SEM (Serial block face scanning electron microscopy). The 1961 TIFF images were compressed to a zip file.</p> <p>The juveniles were fixed at 10.5 hours post fertilization, 30 min after the tail shift (Nishida, H., 2008 Development of the appendicularian Oikopleura dioica: culture, genome, and cell lineages. Dev. Growth Differ. 50, S239–S256.). The dataset would be used as a basic morphological data of this animal to explore organ structures and cellular composition at electron microscopic level.</p> <p>This data is related to the paper, 3D reconstruction of structures of hatched larva and young juvenile of the larvacean Oikopleura dioica using SBF-SEM. (Scientific Reports, 2021, 11, 4833) (https://www.nature.com/articles/s41598-021-83706-y)</p>

Scanning electron microscopy (SEM) images of single bacterial-Pb tolerant isolates
<p><strong>In-Vitro Trace Element Uptake by Bacteria in Liquid Cultures-Scanning Electron Microscopy </strong><strong>(SEM-EDX) Analysis</strong><br>Batch studies were conducted using 50 mL Falcon tubes that contained 25 mL GY rich medium supplemented with 100 mg L-1 of Pb (Pb(NO3)2). All tubes were inoculated with 1 mL of a bacterial cell suspension (optical density at 600 nm = 1), which was previously grown in GY medium at 28 °C for 24 h. Samples were incubated at 28 °C and 100 rpm on an orbital shaker.<br>In order to estimate Pb sequestration by bacterial cells, cultures were first centrifuged 15 min at 4800 rpm, bacterial pellets were washed 3 times with 0.01 M phosphate-buffer (PBS, pH 7.0) to remove unbound metals, sugars and proteins. The samples were dehydrated with ethanol/water mixtures, until absolute ethanol. Then 100% acetone was used. Pellets were resuspended in 2% glutaraldehyde for 1h at room temperature. Afterwards, bacterial samples were centrifuged for 3 min at 3000 rpm and pellets were washed 3 times with milli-Q water. One uL of sample was placed on a sample holder, in carbon conductive tape. Then, samples were coated 30 s with a 15 nm gold layer and analysed using a Scanning Electron Microscope (<span>Phenom™ ProX Desktop, Thermofisher</span>). Images were taken using an accelerating voltage of 15 kV.</p> <p><em>Bacillus paramycoides</em> ST4, <em>Bacillus wiedmannii</em> ST29 and <em>Bacillus proteolyticus </em>ST9 <span>images obtained by SEM-EDX are presented in this dataset. Pb was found present in/on the bacterial cell wall of these bacteria cultures and detected by EDX spectra. </span></p>
Scanning electron microscopy (SEM) images of particulate matter collected on air filters
<p>Airborne PM sampling was conducted within a larger study on the PM composition of different areas in Santa Rosa, La Pampa, Argentina by Prof. Dr. Mendez Mariano. Airborne PM10 samples were collected on commercial 47mm diameter PTFE membrane filters (Image 1-blank) and Nylon filters (Image 2-blank). The PM10 was collected using an electrostatic precipitator coupled with the Easy Dust Generator (EDG). Filters were analysed using a Scanning Electron Microscope (Phenom™ ProX Desktop, Thermofisher). Images were taken using an accelerating voltage of 15 kV. SEM-EDX results are presented in this dataset.</p>

Raw, unprocessed SEM data images for: Figure 1: Scanning electron microscope images of "type-1 bone collagen" demineralized bone matrix fibrils
<p>Raw, unprocessed SEM data images for Figure 1 of the manuscript: Scanning electron microscope images of "type-1 bone collagen" demineralized bone matrix fibrils. (A) Fibrils from the <em>B</em>. <em>taurus</em> extant long bone control. Prominent banding (~67nm) is present that is characteristic of type-1 collagen protein fibrils (Boatman et al., 2019; Gottardi et al., 2016; Lin et al., 1993; Rabotyagova et al., 2008; Tzaphlidou, 2005). (B) Permafrost YG 610.2397 <em>M</em>. <em>primigenius</em> demineralized bone matrix fibrils. An ~67nm banding pattern on the fibrils is also observed but is somewhat less distinct in comparison to that of the extant <em>B</em>. <em>taurus</em> specimen. (C) Observed fibril structures in the temperate MOR 91.72 <em>M</em>. <em>columbi</em> specimen. Fibril banding is generally absent, suggesting the original chemical state of the type-1 collagen fibrils/sequences is substantially altered.</p>
SEM imaging data used in "Investigation of the porosity of L/LL4 ordinary chondrite Bjurböle using synchrotron radiation microtomography and scanning electron microscopy: Implications for parent body evolution"
<p>SEM imaging data used in ”Investigation of the porosity of L/LL4 ordinary chondrite Bjurböle using synchrotron radiation microtomography and scanning electron microscopy: Implications for parent body evolution” contains images of a polished section of a 0.35 cm<sup>3</sup> sample of Bjurböle obtained using scanning electron microscopy (SEM) in backscattered electron mode (pixel size 0.55 µm), as well as elemental maps of some details of the sample obtained by an energy dispersive spectrometer, as zip archives. Folder SEM contains the images covering the entire polished section. Bulk porosity of the sample was determined to be 21.9 vol% using a gas pycnometer. </p>
