On October 27, 2023, I presented a seminar in the GRADUATE PROGRAM IN PHYSICS entitled “Nanomaterials: Synthesis and Characterization at UFSC and in “Large Facilities” in Brazil and in the World” in which I outlined some of the perspectives for future work that, certainly, will require human resources at post-graduate level.
The recording of the seminar can be accessed via the YouTube link.
Summary:
In this presentation, I intend to show some of my motivations for developing research in Nanoscience and Nanotechnology. A brief introduction will be given to what nanomaterials are and how they fit into the description of functional materials. I will mention the main methods for synthesizing nanomaterials and will emphasize mechanochemical synthesis, which I have used in the NanoMaterial Synthesis and Characterization Laboratory (LSCnM) of the Department of Physics at UFSC since 2001. I will begin the description of nanomaterial characterization techniques by showing those available in UFSC. I will give a panoramic view of how large laboratories, known as “Large Facilities”, in Brazil and around the world, are important for a better understanding of the physicochemical properties of nanomaterials and how these are decisive in the development of new materials. The expectation is that at the end of the presentation, some students will feel motivated to get involved in research on the development and characterization of new nanomaterials with potential future applications in the areas of energy and sustainability. I hope to attract post-graduate students to work under my guidance on scientific projects involving “green” synthesis and characterization of nanocrystalline chalcogenides with applications in thermoelectricity, superconductivity, electroanalytic, catalysis, etc.
I believe that the opportunities for use and news about the large Brazilian laboratories (Sirius and RMB) may be of interest to the UFSC community involved in scientific research involving materials.

Title: Characterization and applications of mechanochemically synthesized Chalcogenide powders
Speaker: Prof Carlos Campos, Department of Physics at the Federal University of Santa Catarina (UFSC) in Brazil
ABSTRACT
The combination of several experimental techniques and the microstructural modeling including the volume-weighted diameter size, surface-weighted ’true’ crystallite size for an ellipsoidal domain shape as well as the Debye Function (DFA) overcome conventional methods of analysis (notably the Rietveld method) that fail to consider important information contained in diffuse scattering, typically of disordered and/or nanometric materials.
This seminar is devoted to showing some results on these modeling for the Fe56Te44 and CoxTe100-x (with x = 32, 34, and 40) samples. Moreover, a brief overview of novel electrochemical sensors based on carbon paste electrodes (CPE) will be delivered. For instance, (CPE)/Ni3-xTe2 applied for the simultaneous detection of the neurotransmitters dopamine (DA) and adrenaline (AD) in phosphate buffer solution (pH 7.0), a CPE/NiTe2 successfully applied to morin determination in high, medium, and low polyphenols content red wines such as Tannat, Cabernet Sauvignon, and Pinot Noir, as well as the γ-CoTe2 nanocrystals (γ-CoTe2/GCE) with outstanding sensing abilities for ferulic acid. All the Iron, Nickel, and Cobalt Telluride composites were prepared by mechanochemical route in just a few hours and carefully characterized by X-ray diffraction, calorimetry, transmission electron microscopy, Raman spectroscopy, and magnetometry techniques.
At the end of the presentation, a few perspectives of complementary characterization using neutrons and synchrotrons will be presented with a focus on thermoelectric materials.

Review article in a high impact factor journal (Chemical Society Reviews) on the use of mechanochemical methods to study their reactivity in the production of organometallic nanoparticles cited 4 scientific articles with research done at LSCnM of the UFSC Department of Physics. PPGFSC students at UFSC were at the forefront of all publications. The review article compiles the recent literature on the use of mechanochemical methods in the production of nanoparticles to organometallics. Also, present an overview of mechanochemical reactivity that complements recent developments in organic synthesis and catalysis
“Mechanochemistry by grinding, grinding, extrusion or other types of mechanical shear and repair has new reactivity for a wide range of reactions not seen in traditional solution-based environments.”

WHAT ABOUT LEARNING TO PRODUCE NANOMATERIALS USING MECHANICAL ENERGY AND CHARACTERIZE THEM USING X-RAYS, ELECTRONS, LASER AND MANY COMPUTATIONAL TOOLS?
Research Project aims to train human resources specialized in the use of
experimental Physics techniques, such as Polycrystals X-Ray Diffraction (XRD), Raman Spectroscopy (ER), in the characterization of the physical properties of
nanomaterials and organic crystals produced by various methods of synthesis, especially
mechanochemistry. See the multi-user facilities available to develop the activities in this project:
LabCAM,
LCME,
LDRX and
LNLS/CNPEM . Five IC students have already been carrying out experiments in the old LNLS accelerator (UVX, approved proposals for the use of beamlines DXAS, XDS, XDR1).

Master’s student at PPGFSC-UFSC, Marcelo Augusto Malagutti, was awarded for the second consecutive time with the “ROBERT L. SNYDER STUDENT AWARD” award and will present work orally at the Denver X-ray Conference, which will take place between August 2nd and 6th 2021, virtually this year due to the pandemic.
Discente do PPGFSC, Marcelo Augusto Malagutti
The work entitled “Structural and Microstructural X-Ray Diffraction Analysis of the β-CoTe Nanophase Synthesized by Mechanochemistry: Anisotropic Size and Microstrain Modeling” (D-21 of the General XRD session) is a compilation of the 1st article published by the student in co-authorship with Prof Carlos EM Campos (advisor), the newly graduated doctor from PPGFSC-UFSC, Kelli de Fátima Ulbrich, in close cooperation with researchers Julian Geshev and Vagner Zeizer Carvalho Paes, from the Physics Institute of the Federal University of Rio Grande do Sul. The student will present recent results of his studies on the microstructure of nanocrystalline materials produced by him using more sophisticated mathematical models to explain experimental data from their samples analyzed in various X-Ray diffraction laboratories (including the LDRX-UFSC, (including synchrotron light sources such as LNLS e SLS).
Parabéns Marcelo!
