The TEM specimen was cleaned using an ion cleaner (JEC-4000DS, JEOL Ltd) before the STEM experiments. For STEM analyses, the semiconvergence angle was set to 24 mrad and the semicollection angle range was set to 12–24 mrad. To minimize scan distortion and enhance the signal-to-...
The results showed that when the aspect ratio was less than 1.5, the measurement results in the middle of the specimen were optimal, and the accuracy increased when the cutting depth was greater than 1/5 of the width; in addition, the results differed from those obtained with the X-ray ...
Specimen placement. The rock sample attached with casing is placed into the core holder, and the confining and axial stress are then applied to the sample through hydraulic pump; (3). Vacuum processing. Open vacuum pump to test the blocking or leakage problem and vacuum the plunger pump and ...

Cryogenic electron microscopy (cryo-EM) is widely used to determine near-atomic resolution structures of biological macromolecules. Due to the low signal-to-noise ratio, cryo-EM relies on averaging many images. However, a crucial question in the field of
