GQM is headed by Prof. Aldo J. G. Zarbin.

 

Our research focuses in synthesis of nanocomposites based in different 2D materials, such as Ttransition metal dichalcogenides (TMD's), carbon nanostructures and several other materials, such as metallic nanoparticles, polymers and inorganic complexes.

 

Mostly processed as thin films, our nanocomposites are applied as batteries, capacitors, catalysts, photovoltaic devices, sensors and electrochromic materials.

Vinícius Costa's Qualification

Last week, Vinicius Costa successfully presented his master work titled, “Bifunctionalized nanocatalysts for the degradation of organophosphates”. Professor Elisa Orth guided the defense and included co-supervisor Professor Aldo Zarbin as well as Professors Marcela Mohallem Oliveira and Christian Wittee. Kudos to Vinícius for achieving this milestone! We wish him a stellar journey in the world of science. Our heartfelt thanks to the entire evaluation committee. We eagerly await the upcoming GQM defense.

New Raman Spectrometer

Recently, GQM made a significant addition to its arsenal with the acquisition of a cutting-edge Raman spectrometer. With the launch of the INCT NanoVida project, we were able to procure an automated Raman imaging microscope, the alpha300R apyron, from WITec – Oxford Instruments. WITec's Raman microscope alpha300 R at the forefront of the technology and sets the benchmark in terms of flexibility, sensitivity, speed and performance. These unique characteristics have established the alpha300 R the preeminent confocal Raman imagining system on the market. Moreover, the project facilitated the refurbishment of a room within the UFPR chemistry department to ensure optimal conditions for the installation and operation of the new equipment. We extend our heartfelt gratitude to all involved in the procurement, delivery, renovation, installation, and training processes of our latest addition. Stay tuned for upcoming discussions on our Raman capabilities and the groundbreaking scientific research to come.

Ariane Schmidt's PhD Defense

Professor Aldo Zarbin guided the defense and included co-supervisor Professor Camilla de Oliveira as well as Professors Lucimara Stolz Roman, Izabel Riegel Vidotti, and Christian Wittee Lopes. Congratulations Mandy! We wish you a stellar journey in the world of science. Our heartfelt thanks to the entire evaluation committee. We eagerly await the upcoming GQM defense.

LatinXChem 2023

Today is happening the LatinXChem, a global virtual platform for Latin American chemists to showcase and discuss their research advancements. In its inaugural edition, we witnessed submissions of over 1,200 posters from 43 countries, generating an impressive 20 million Twitter impressions.

The upcoming event by @LatinXChem is the #LatinXChem23 Conference, scheduled for October 16th and 17th, 2023.

Our GQM team is proudly presenting their work. Dive into each of their projects and engage with our material scientists: Amanda (#NanoMat079), André (#NanoMat056), Ariane (#NanoMat115), Carla (#NanoMat083), Eduarda (#NanoMat102), João Victor (#NanoMat099), Maria (#NanoMat108), Mayara (#NanoMat110), and Vinícius (#NanoMat059). From the realm of physical chemistry, we have Bernardo (Phys10). And representing the analytics sector, Denys (#Ana46).

XXI SBPMat

The XXI meeting of the Brazilian Society for Research in Materials (XXI SBPMat) took place in Maceió-Alagoas, Brazil, from October 1 to 5, 2023. This is a traditional event dedicated to recent advances and perspectives in materials science and related technologies. It was an excellent meeting that brought together scientists, engineers and students from academia and industry to discuss the state of the art of discoveries and perspectives in Materials Science. Professor Aldo Zarbin participated in the event and gave an oral presentation with the work “2D-materials based nanocomposite thin films for electrodes in aqueous and transparent Na- or K-ion batteries”.

49th IUPAC World Chemistry Congress | 11th CHAINS conference

Last week, GQM traveled to Netherlands for the 49th IUPAC World Chemistry Congress, held jointly with the 11th CHAINS conference, the most extensive chemistry gathering. Hosted in Haia city, the event carried the theme 'Connecting Chemical Worlds', and it attracted a broad spectrum of chemists from academia and industry worldwide. The IUPAC|CHAINS2023 event was spearheaded by the Royal Dutch Chemical Society (KNCV) and the Dutch Research Council (NWO). Held biennially, the IUPAC World Chemistry Congress has seen recent editions in São Paulo (2017), Paris (2019), and a digital version in Montreal (2021). At this year's congress, Professor Aldo Zarbin delivered two outstanding talks. One was during the focus session on "Materials and Interfaces for Next-Generation Batteries", and the other was centered on "Advanced Thin Film Technology of Energy and Smart Materials".

Denys Ribeiro's Qualification

Yesterday, Denys Ribeiro successfully presented his PhD work titled, “Construction of multivalent platforms for the development of electrochemical and optical bio(sensors)”. Professor Dênio Emanuel Pires Souto guided the defense and included co-supervisor Professor Aldo Zarbin as well as Professors Elisa Orth, Marcela Oliveira, and Herbert Winnischofer. Kudos to Denys for achieving this milestone! We wish him a stellar journey in the world of science. Our heartfelt thanks to the entire evaluation committee. We eagerly await the upcoming GQM defense.

Prof. Aldo Zarbin is awarded the Order of Merit medal

What an incredible moment! Professor Aldo Zarbin has just been awarded the prestigious Order of Merit medal by President Lula. This distinguished recognition is bestowed upon national and international figures who have made significant contributions to the advancement of science, technology, and innovation in Brazil. The Federal Government, specifically the Ministry of Science, Technology, Innovations, and Communications, presents this esteemed award. In 2021, due to the previous president's revocation of the honor for two researchers who had undertaken work that was unfavorable to the government, twenty-one scientists declined the Order of Scientific Merit medal. Today, it is an absolute honor to witness these esteemed researchers finally receiving well-deserved recognition from President Lula! We are thrilled to be a part of this momentous occasion. Congratulations, Professor Comendador Aldo Zarbin!

PhD defense of Cristian Souza

Yesterday, we celebrated the successful PhD defense of Cristian Souza, whose remarkable research titled " Thin films of nanocomposites between different carbon and pedot nanomaterials at liquid interfaces: preparation, characterization and properties study ". Professor Aldo Zarbin guided the defense, with the participation of professors Lucimara Roman, Sérgio Domingues, Márcio Peres e Kahlil Schwanka Salome. Congratulations on your work, Cris, and may your scientific journey be filled with brilliance!! We extend our heartfelt gratitude to the entire professors for their valuable participation, and we eagerly look forward to the next GQM defense.
