New tomography technique developed at CENEM highlighted on the cover of Small Methods

In the research paper Thomas Przybilla, Benjamin Apeleo Zubiri and co-workers present a versatile approach that provides a general routine for advanced 3D characterization of micro- and nanoparticles. The method which was developed at IMN and CENEM involves the transfer of individual particles onto tailored tips using a scanning electron microscope equipped with a micromanipulator. The damage- and contamination-free preparation of freestanding particles enables 360° electron tomography with unprecedented quality as demonstrated for porous zeolite microparticles and alpha-hematite nanoparticles.
