So while it is difficult to image a nanocluster in the imaging mode, SAED measurements can be useful for the analysis.
Although the circular pits of some hundred nanometers could be seen via SEM imaging, it remained difficult to image primary titania particles.
With currently available imaging technologies, it is difficult to image the fine moving structures such as valve leaflets and chordae tendinae with the image quality sufficient enough for 3D printing.
However, we cannot exclude the possibility that Fn rearrangement occurred on the vertical walls since these surfaces were perpendicular to the confocal imaging plane and therefore difficult to image.
It is difficult to image deep into cells with single-molecule imaging techniques.
MAD-LEEM is designed for the purpose of imaging biological and insulating specimens, which are difficult to image with conventional LEEM, Low-Voltage SEM, and TEM instruments.
The methods described in this paper provide a straightforward and reliable means for imaging a class of samples that, until now, have been very difficult to image.
It is difficult to image anyone less suited to the role.
In the intervening 25 years, her influence on recorded music has been huge – it's difficult to image Tori Amos, Björk, even Lady Gaga without her.
When such features cross-cut the borehole, they are particularly difficult to image.
But thin, warm structures--such as the supposed plumes--would be particularly difficult to image in the conventional manner.
