Controlling radiation damage in nanomaterials
Nanomaterials are offering unique opportunities for the design of future nuclear materials. In our recent paper at ACS Applied Nano Materials, we demonstrate that AISI-316 steel nanoparticles are capable of self-healing from the deleterious effect of heavy-ion collisions. We also pose a new question to the materials community on the recyclability of potential nuclear nanomaterials. … Continue reading Controlling radiation damage in nanomaterials
Functionally Graded Materials for Fuel Cells Applications
Our paper on the corrosion resistance of constant and functionally graded TiN coatings is now online! In this paper we have discovery an interesting relationship between electron energy loss spectroscopy and corrosion resistance: functionally graded materials can be engineered so that they have a gradient of valence electrons along the coating profile. The less electrons … Continue reading Functionally Graded Materials for Fuel Cells Applications
Ce nanoparticles as a corrosion inhibitor in Al 2xxx series alloys!
With great pleasure I am sharing to all of you the first paper performed in collaboration with the research group of Professor Hercílio de Melo in the field of corrosion of Al alloys 2xxx series. In this paper we report that Ce-containing nanoparticles -- when stuck to the inherent porous walls of anodized layers -- … Continue reading Ce nanoparticles as a corrosion inhibitor in Al 2xxx series alloys!
“A ciência que investiga e joga luz no irreconhecível precisa ocupar um lugar de destaque na sociedade, por seus méritos, dedicação e capacidade de preparar caminhos mais saudáveis para a humanidade. Um esforço voltado para redesenhar a sociedade brasileira, que hoje sangra em seus fundamentos, inclusive nos democráticos.”
Compartilhando um artigo extremamente interessante escrito pelo Professor Glauco Arbix (FFLCH-USP); Revista USP de Estudos Avançados: https://www.revistas.usp.br/eav/article/view/173371/162559
“7% of the Brazilian population – some 11 million people – believe that the Earth is flat”
Yes, you read it correctly: the education levels in Brazil are worrying. Part of the society is just completely ignorant and turning into conspiracy-theory believers due to the aid of social networks. Sharing a very interesting news article from Physics World, a monthly publication from the Institute of Physics! Read everything at: https://physicsworld.com/a/fighting-flat-earth-theory/
Nuclear Mystery from IAEA: “Low Levels of Radioisotopes Detected in Europe Likely Linked to a Nuclear Reactor”
28/2020Vienna, Austria https://www.iaea.org/newscenter/pressreleases/low-levels-of-radioisotopes-detected-in-europe-likely-linked-to-a-nuclear-reactor-iaea The recent detection of slightly elevated levels of radioisotopes in northern Europe is likely related to a nuclear reactor that is either operating or undergoing maintenance, when very low radioactive releases can occur, the International Atomic Energy Agency (IAEA) said today. The geographical origin of the release has not yet been determined. … Continue reading Nuclear Mystery from IAEA: “Low Levels of Radioisotopes Detected in Europe Likely Linked to a Nuclear Reactor”
Cutting edge Aluminium metallurgy!
Under the supervision of Professor Stefan Pogatscher and in collaboration with a strong scientific network, I am delighted to share our two "most fresh" papers pushing up the frontiers of Aluminium Metallurgy. The first "Age-hardening response of AlMgZn alloys with Cu and Ag additions" is a comprehensive assessment on the heat-treatment response and mechanical properties … Continue reading Cutting edge Aluminium metallurgy!
Life after death?
The modus operandi of science is skepticism. It is indeed! And we scientists should take this very seriously in order to avoid possible mystification during the course our professional life. We are skeptical, although we are allowed to talk about the unknown and try to reach some subjective conclusions based on our own life experiences. … Continue reading Life after death?
History, scientists and metallurgy (1)
