The Electron Microscopy Laboratory ( Laboratório de Microscopia Eletrônica, LME) is an open facility laboratory offering tools to characterization of materials. The LME is not a service laboratory, so researcher and users have full responsibility on the preparation and study of their samples. Users lacking of experience on Electron microscopy will be trained until become proficient on the operation of the equipment.

Besides the complete infra-structure for sample preparation (both for scanning electron microscopes and for transmission electron microscopes), the laboratory has 5 Electron microscopes. They are:

  • A Transmission Electron Microscope with a field emission gun (FEG-TEM/STEM: JEM 2100F URP) dedicated to nano-analises by EELS (Electron Energy Loss Spectroscopy) and by XEDS (X-ray Energy Dispersive Spectroscopy);
  • A High-Resolution Transmission Electron Microscope (HRTEM, JEM 3010 URP);
  • A Transmission Electron Microscope for Material Science (TEM-JEM 2100 ARP);
  • A  Scanning Electron Microscope  (SEM-FEG JSM 6330F) with a field emission gun (FEG);
  • A Scanning Electron Microscope operating in Low Vacuum (SEM-LV JSM 5900).

Recent History

The LME started its activities as an open user facility in March 1999. Since it belongs to a National Laboratory, it has users from all over Brazil offering analytical techniques with high spatial resolution for strategic researches like nano-science and nanotechnology. Often, knowledge developed in this laboratory may be applied, favoring the Brazilian economy.

The research performed at the LME by its users embrace many field like, for instance:

  • Semiconductor Physics used in electronics devices circuits;
  • Spintronics (physics) to enable the next generation of electronic circuits;
  • Catalysts (chemistry) employed in the petrochemical industry;
  • Gas sensors (chemistry) employed in the detection of pollution;
  • Parasitology (biology) in the development of new treatments;
  • Ceramics (material engineering) for the development of new materials to be used in the aircraft industry;
  • Metallurgy (material engineering) for the development of new steels for the car industry;
  • Fuel Cells (Physical-chemistry) for application in the car industry for electric vehicles;


Moreover, the laboratory has users from many institutions. A partial list of these institutions is: CBPF, CENPRA, CTA, INMETRO, INPA, INPE, IPEN, PUC – RJ, PUC – Campinas, PUC-SP, UFC, UFPE, UFMG, UFMT, UFRGS, UFRJ, UFSCar, UNB, UNESP, UNG, UNICAMP, UNICENP, UNIMEP, UniVap, UNLP, USF, USP, UEL, UFPR, UFSC, UFOP.
