Advanced electron microscopy: new paradigms for studying nanomaterials

In this webinar, you will learn about the remarkable progress achieved by electron microscopy instrument to answer applied and basic questions raised by the constantly growing field of nanotechnology.

We will present a series of studies of nano objects (such as molecules, nanoparticles, nanotubes, nanowires) to provide examples on the need to change our views of experiment design, execution and analysis. Previously, it was common to think that electron microscopy as a very useful but qualitative atom resolution imaging tool for materials science. At present, researchers must use these advanced tools in association with physicochemical simulations, machine learning, big data, etc.  to target the generation of reliable and quantitatively verified physical models from the measurements.

Finally, it is very important to exchange ideas on how to approach the critical problem of human resources formation associated with complex modern analytical techniques and, how to make these onerous instruments accessible by the operation of multi-user facilities/networks.

Prof. Ugarte will discuss his experiences to tackle these issues in the context of a South American country.

Daniel Ugarte is professor at the Institute of Physics, Universidade Estadual de Campinas (UNICAMP), Brazil. He obtained his degree in physics at the Universidad Nacional de Córdoba (Argentina) and finished his PhD at the Université Paris-Sud. After a postdoc at the Ecole Polytechnique Federale de Lausanne, he joined the Brazilian Synchrotron Light Laboratory (LNLS, Brazil) in 1993. He moved to the Institute of Physics Gleb Wataghin, Universidade Estadual de Campinas (UNICAMP) in 2004, where he acts as full professor. His activities have been related with the experimental study of structural and electronic properties of nanoscale systems, mainly using electron microscopy methods. At the end of nineties, he designed and created the Brazilian National Center of Electron Microscopy; this lab was the seed to the subsequent creation of the Brazilian National Nanotechnology Laboratory (LNNANO) in Campinas. Daniel has published approximately 120 journal papers, several in high-impact journals (including Nature, Science, Nature Nano, Phys. Rev. Lett., Nano Lett.). His articles have received approximately 18,000 citations (Google Scholar). He has given approximately 100 invited talks in prestigious international conferences among them APS March Meeting, MRS Fall Meeting, Gordon Conference. He received several national and international awards, among them are Guggenheim Fellowship (USA, 2002), Latsis (Switzerland, 1994) and recently the TWAS Prize in Physics in 2018. He was elected member of the Brazilian Academy of Sciences in 2012 and of The World Academy of Sciences (TWAS) in 2019.
