    Collapse Overview 
    Collapse overview
    My research is focused on the study of the crystalline structure of materials and their physical properties through transmission electron microscopy (TEM) and electron diffraction. Physical properties (magnetic, optical, electric and mechanical properties) are measured in situ TEM, in which individual nanostructures are exposed to external stimuli and recorded in real time. Electron microscopy methods include off-axis electron holography, high resolution transmission electron microscopy, aberration-corrected TEM and STEM, and electron diffraction under different modes: SAED, Scanning NBD and Crystal orientation mapping using precession electron diffraction. My work covers both, theory and experimental aspects of the crystalline structure/physical property relationships based on the electron-matter phenomena.

    PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
