Shadow montage and cone-beam reconstruction in 4D-STEM tomography
Microscopy and MicroanalysisAbstract Diffraction images in a scanning transmission electron microscope (STEM) provide a real-space projection of the sample at sufficient probe defocus. Such shadow images may be acquired patch by patch in a 4D-STEM setup using a pixelated detector and assembled into a shadow montage.

Optimizing contrast in automated 4D-STEM cryo-tomography
Microscopy and MicroanalysisAbstract 4D STEM is an emerging approach to electron microscopy. While it was developed principally for high-resolution studies in materials science, the possibility to collect the entire transmitted flux makes it attractive for cryomicroscopy in application to life science and radiation-sensitive materials where dose efficiency is of

Biomaterials for 4D stem cell culture. [PDF]
Curr Opin Solid State Mater Sci, 2016 Stem cells reside in complex three-dimensional (3D) environments within the body that change with time, promoting various cellular functions and processes such as migration and differentiation. These complex changes in the surrounding environment dictate cell fate yet, until recently, have been challenging to mimic within cell culture systems. Hydrogel-
