Fig. 1 in The extent of the pterosaur flight membrane
Fig. 1. Schematic sketch of Pterodactylus as viewed in its inferred flight position from ventral view (adapted from Wellnhofer 1970). The three flight membranes are illustrated with the brachiopatagium, the focus of this work, being shaded in grey. All terminology is applied to the animal in this position and the size of any specific chord is here generally defined as being narrow or broad, large or small. While the root chord should generally also include the chord of the propatagium for the purpose of this paper it is restricted to the brachiopatagium.

Fabrication of Spherical Colloidal Supraparticles via Membrane Emulsification
<p>This is the raw data for the manuscript "Fabrication of Spherical Colloidal Supraparticles via Membrane Emulsification".</p> <p>Abstract</p> <p>Colloidal supraparticles are micron-assemblies of primary particles. These supraparticles have potential application in photonic materials, catalysis, gas adsorption and drug delivery. Thus, synthesis of colloidal supraparticles with a narrow size distribution and high yield has become essential for their application in different fields of science and technology. Here, we demonstrate membrane emulsification as a high-throughput approach for fabricating spherical supraparticles with narrow size distribution and control over particle size and crystallinity. Spherical supraparticles with well-ordered surface structures are synthesized by generating emulsion droplets of an aqueous colloidal dispersion in fluorocarbon oil using a Shirasu Porous Glass membrane, followed by the consolidation of particles through water removal within the emulsion. We systematically investigate process parameters, including the flow rate of particle dispersion, particle concentration, and average pore diameter of the membrane on the mean size and size distribution of the supraparticles, revealing key factors governing supraparticle properties and production throughput. Comparative evaluation with commonly employed methods highlights the advantage of membrane emulsification, which combines well-defined internal structure and controlled supraparticle sizes with comparably high yields in the order of tens of grams per day. Importantly, in contrast to widely-used droplet-based microfluidics, membrane emulsification allows fabrication of supraparticles in non-fluorinated oil. Overall, membrane emulsification offers a simple yet versatile method for fabricating colloidal supraparticles with high quality and yield and may serve as a bridge between existing high-precision techniques such as droplet-based microfluidics and high-throughput processes with less control such as spray drying</p> <p>All data are sorted according to thier appearance in the figures of the main manuscript and the supporting infomation.

<h2>Dataset description</h2> <p>This dataset provides the raw data for the manuscript "Photodeposition-Based Synthesis of TiO<sub>2</sub>@IrO<sub>x</sub> Core-Shell Catalyst for Proton-Exchange Membrane Water Electrolysis with Low Iridium Loading"<strong> </strong>published in <em>Advanced Science </em>on 14 June 2024 (DOI: <a href="https://doi.org/10.1002/advs.202402991">https://doi.org/10.1002/advs.202402991</a>).</p> <p>The data consists of:</p> <ol> <li>XRD pattern of TiO<sub>2</sub>@IrO<sub>x</sub> (40 wt% Ir) as shown in Fig. 3e.</li> <li>XPS spectra of 3 samples: <strong>2.1</strong> TiO<sub>2</sub>@IrO<sub>x</sub> (40 wt% Ir) as shown in Fig. 3f.; <strong>2.2 </strong>TiO<sub>2</sub>@IrO<sub>x</sub> (only shell) as shown in Fig. 3g; <strong>2.3</strong> TiO<sub>2</sub>@IrO<sub>x</sub> (photodeposited seeds) as shown in Fig. S8.</li> <li>Datasets for NanoCT of the TiO<sub>2</sub>@IrO<sub>x</sub> catalyst layer as shown in Fig. 5 a-c : <strong>3.1</strong> HRES Tilt series; <strong>3.2 </strong>reconstructed slices.</li> </ol> <h2>Abstract</h2> <p>The widespread application of green hydrogen production technologies requires cost reduction of crucial elements. To achieve this, a viable pathway to reduce the iridium loading in proton exchange membrane water electrolysis (PEMWE) is explored. Herein, we present a scalable synthesis method based on a photodeposition process for a TiO<sub>2</sub>@IrO<sub>x</sub> core-shell catalyst with a reduced iridium content as low as 40 wt%. Using this synthesis route, we obtain titania support particles homogeneously coated with a thin iridium oxide shell of only 2.1 ± 0.4 nm. The catalyst exhibits not only high ex situ activity, but also decent stability compared to commercially available catalysts. Furthermore, the unique core-shell structure provides a threefold increased electrical powder conductivity compared to structures without the shell. In addition, the low iridium content facilitates the fabrication of sufficiently thick catalyst layers at decreased iridium loadings mitigating the impact of crack formation in the catalyst layer during PEMWE operation. We demonstrate that the novel TiO<sub>2</sub>@IrO<sub>x</sub> core-shell catalyst clearly outperforms the commercial reference in single-cell tests with an iridium loading below 0.3 mg<sub>Ir</sub> cm<sup>‑2 </sup>exhibiting a superior iridium-specific power density of 17.9 kW g<sub>Ir</sub><sup>-1 </sup>compared to 10.4 kW g<sub>Ir</sub><sup>-1 </sup>for the commercial reference.</p>

Figure 1 in Embryo retention, character optimization, and the origin of the extra-embryonic membranes of the amniotic egg
Figure 1. Sarcopterygian phylogeny showing an optimization of embryo retention (character 1), as previously advocated by Laurin and Girondot (1999). The only modification is that all terminal taxa are in the present tree, instead of collapsing Monotremata and Theria into Mammalia, to better match the character distribution shown in Table I, and that Actinistia is coded as unknown (as shown by the absence of a data box below that taxon).
Figure 3 in Embryo retention, character optimization, and the origin of the extra-embryonic membranes of the amniotic egg
Figure 3. Sarcopterygian phylogeny showing an optimization of the developmental stage at oviposition (character 2, with ordered states). This optimization suggests that the ancestral amniote laid its eggs at the gastrula developmental stage (equivalent to absence of extended embryo retention). If the character is left unordered, the ancestral condition for amniotes is to lay eggs in the post-neurula embryonic stage (equivalent to presence of extended embryo retention).
