Previously housed at the CNPEM Nanotechnology unit, the JEOL TEM-2100 is now dedicated exclusively to undergraduate activities. With it, students will be able to investigate materials at extremely small scales, incorporating transmission electron microscopy into the teaching and research activities developed throughout the course.  <\/p>\n\n<p class=\"wp-block-paragraph\">Segundo a professora Val\u00e9ria Spolon Marangoni, coordenadora de laborat\u00f3rios da Ilum, o microsc\u00f3pio ser\u00e1 incorporado \u00e0s pr\u00e1ticas de disciplinas experimentais e tamb\u00e9m a projetos de pesquisa dos estudantes. \u201cJ\u00e1 nesta etapa inicial, o equipamento est\u00e1 sendo disponibilizado para atividades did\u00e1ticas de Laborat\u00f3rios Avan\u00e7ados, Inicia\u00e7\u00e3o \u00e0 Pesquisa I e Projetos Finais\u201d, explica. <\/p>\n\n<p class=\"wp-block-paragraph\">According to Professor Val\u00e9ria Spolon Marangoni, coordinator of laboratories at Ilum, the microscope will be incorporated into the practices of experimental disciplines and also into students&#8217; research projects. \u201cEven at this initial stage, the equipment is being made available for educational activities in Advanced Laboratories, Introduction to Research I, and Final Projects\u201d, she explains. This new equipment reinforces the institution\u2019s pedagogical approach, which combines technical experience and theory. &#8220;The idea is that students not only have theoretical contact with electron microscopy, but can understand how the technique works, follow the preparation and analysis of their own samples and, progressively, participate in obtaining and interpreting the data\u201d, says Val\u00e9ria Spolon. <\/p>\n\n<p class=\"wp-block-paragraph\"><strong>What the microscope allows you to see<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Imagine looking at something thousands of times smaller than the thickness of a human hair. It is at this scale that Ilum\u2019s transmission electron microscope operates. Instead of light, it uses an electron beam that passes through the sample and generates extremely high-resolution images.  <\/p>\n\n<p class=\"wp-block-paragraph\">Mas o equipamento mostra mais do que a forma dos materiais observados: ele tamb\u00e9m permite investigar como os \u00e1tomos est\u00e3o organizados, o que os cientistas chamam de estrutura cristalina, al\u00e9m de identificar a composi\u00e7\u00e3o dos elementos qu\u00edmicos. Essas informa\u00e7\u00f5es s\u00e3o importantes porque essas caracter\u00edsticas influenciam diretamente as propriedades do objeto analisado. <\/p>\n\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/ilum.cnpem.br\/wp-content\/uploads\/2026\/10\/image.jpeg\" alt=\"\" class=\"wp-image-58277 lazyload\" style=\"aspect-ratio:1.5014005602240896;width:536px;height:auto\"><noscript><img decoding=\"async\" width=\"670\" height=\"446\" src=\"https:\/\/ilum.cnpem.br\/wp-content\/uploads\/2026\/10\/image.jpeg\" alt=\"\" class=\"wp-image-58277\" style=\"aspect-ratio:1.5014005602240896;width:536px;height:auto\" srcset=\"https:\/\/ilum.cnpem.br\/wp-content\/uploads\/2026\/10\/image.jpeg 670w, https:\/\/ilum.cnpem.br\/wp-content\/uploads\/2026\/10\/image-300x200.jpeg 300w, https:\/\/ilum.cnpem.br\/wp-content\/uploads\/2026\/10\/image-599x399.jpeg 599w\" sizes=\"(max-width: 670px) 100vw, 670px\" \/><\/noscript><\/figure>\n\n<p class=\"wp-block-paragraph\">Still undergoing technical adjustments, the microscope, which will be definitively incorporated into the curriculum in 2027, already allows for the analysis of the shape and size of inorganic nanomaterials of approximately 15 nanometers, which is more than 5,000 times smaller than a human hair, which is about 80,000 nanometers thick. In another comparison, the new equipment can analyze substances approximately seven times smaller than the COVID-19 virus, which, however, requires biosafety level 3 laboratories to be handled. <\/p>\n\n<p class=\"wp-block-paragraph\">\u201cMore than simply expanding Ilum&#8217;s equipment park, TEM strengthens a central characteristic of the education we seek: bringing the student closer, from undergraduate studies onwards, to the way science is effectively applied\u201d, points out Spolon. She highlights that the student can participate in all stages of a scientific problem: producing material, formulating hypotheses, characterizing it using different techniques, analyzing data, and relating structure, composition and properties. According to the professor, Ilum already employs other advanced techniques, such as atomic force microscopy and optical spectroscopy.  <\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Access to the technique in undergraduate studies<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Some universities offer access to and training in transmission electron microscopy to undergraduate students, but this usually occurs in the context of research projects or specific training programs in multi-user facilities. The systematic integration of TEM into various curricular projects and undergraduate activities, as proposed by Ilum, is still an unusual initiative in the national and international context. <\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Lise Meitner Laboratory: dedicated infrastructure<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">The microscope will be installed in the new Lise Meitner Laboratory, a space built specifically to house the equipment. The operation of a transmission electron microscope requires a climate-controlled environment to meet the equipment&#8217;s technical requirements. <\/p>\n\n<p class=\"wp-block-paragraph\">The laboratory is named in honor of one of the most important physicists of the 20th century. Born in Vienna, Austria, in 1878, Lise Meitner (1878-1968) overcame the barriers imposed on women in science in her time and earned a doctorate in physics in 1906. She built her career in Germany, where she worked for three decades with chemist Otto Hahn on research into radioactivity and the structure of the atom. Forced to leave the country in 1938 because of her Jewish origin, she continued her research in Sweden. From there, together with her nephew, physicist Otto Frisch, she explained, from a theoretical point of view, how the nucleus of the atom can divide, a process known as nuclear fission. The discovery, which helped change the course of science, earned Hahn the 1944 Nobel Prize in Chemistry, and Meitner&#8217;s contribution was only widely recognized decades later. In her honor, the chemical element number 109 on the periodic table was named meitnerium.      <\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Abou Ilum<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Ilum offers a free undergraduate degree program that utilizes an interdisciplinary approach to train scientists and professionals in science and technology. With an innovative educational model, the three-year full-time bachelor program offers courses that connect life sciences, materials science, data science, artificial intelligence, and the humanities in order to prepare researchers to work in an ethical and collaborative manner in the search for solutions to the global challenges of the twenty-first century.
