MRI: Acquisition of a Field Emission Scanning Electron Microscope

Scanning transmission electron microscopy image of brain tissue from the lateral amygdala of an adult rat. STEM can provide high resolution images of large areas of brain tissue, allowing much more efficient data collection than a traditional TEM.

Twisted hippuric acid single crystals grown from vapor phase as helically twisted needles, non-crystallographic morphology forming at the crystal tip. The mechanical forces necessary for such strong changes in the crystal shape are generated by minor impurities in the growth medium.A. Shtukenberg, B. Kahr, NYU Chemistry

Broader ImpactsThe Zeiss Merlin FESEM fulfills a critical need for a growing effort at NYU in soft matter, molecular materials, biomolecular assemblies, biomaterials, and other advanced materials.

Moreover, the SEM is providing a key boost to the research and training infrastructure at NYU by expanding its materials characterization capabilities, enhancing student and postdoc training, and exposing numerous research visitors from other institutions, including faculty and students from minority-serving institutions, to advanced electron microscopy.

Educational impact

•Incorporated into existing NYU courses, as well as an anticipated new Nanoscale Imaging course.

•Used by visiting summer research faculty and students.

•Emulating a format used for X-ray diffraction, conduct master classes for electron microscopy in collaboration with Zeiss aimed at students, faculty and industrial scientists in the NYC metropolitan tri-state area.
