3D X-ray microscope CT observations of the spinneret were performed using a nano3DX (Rigaku Co., Japan). The spinneret, which had been dissected from a final instar of E. variegata bagworm larvae, was gently washed with distilled water and then dried overnight under room conditions (25 °C and 50% relative humidity). The dried sample was fixed in an upright position on the sample stage and primarily measured using Cr characteristic X-ray radiation (5.4 keV) produced from a high-brilliance X-ray generator (MM007; Rigaku Co., Japan) with 35 kV and 25 mA, which is suitable for visualising the fine structures of organs because of the appropriate X-ray absorption contrast. The field of view in the high-resolution 2D X-ray sCMOS image sensor camera (XSight Micron LC; Rigaku Innovative Technologies Europe s.r.o., Czech Republic) was 0.6 × 0.6 mm2 and the effective pixel size was set to 0.3 μm. The sample was rotated by 180°and 600 projection images were captured in 900 s. Using an FDK algorithm30 (link), 2000 X-ray tomograms with a thickness interval of 0.3 μm were reconstructed.
Mm007
Manufactured by Rigaku
Sourced in Japan
The MM007 is a high-performance X-ray diffractometer system designed for materials analysis. It features a robust and stable goniometer, a high-intensity X-ray source, and advanced data acquisition and analysis capabilities. The MM007 is capable of performing a wide range of X-ray diffraction experiments, including phase identification, structural analysis, and thin-film characterization.

While single crystals of 6–8 for X-ray diffraction analysis were grown by slow diffusion of hexane into their CH2Cl2 solutions at −5 °C. A single crystal of 6–8 was mounted on a Rigaku MM-007 (rotating anode) diffractometer equipped with a Bruker P4 accessory. While the data of 6 and 8 were collected using a confocal monochromator with Mo Kα radiation (λ = 0.71073 Å) in the ω scanning mode at 113 K, data of 7 were collected using a confocal monochromator with Mo Kα radiation (λ = 0.71073 Å) in the ω scanning mode at 293 K, respectively. Data collection, reduction, and absorption correction were performed by the CRYSTALCLEAR program.59 The structures were solved by direct methods using the SHELXS program60 (link) and refined by full-matrix least-squares techniques (SHELXL)61 (link) on F2. Hydrogen atoms were located by using the geometric method. Details of crystal data, data collections, and structure refinements are summarized in Table 3 .
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
