Oportunidade de Contratação de especialista para apoio ao Ministério dos Transportes e Ministério de Portos e Aeroportos para o Plano Clima - Mitigação para o setor de Transportes. PRAZO DE INSCRIÇÃO: 31/07/2024 Resultados esperados: The TRANSPORTATION Sector Expert will be responsible for supporting the Brazilian Ministry of Environment and Climate Change (MMA) in the elaboration of the TRANSPORTATION sector mitigation plan for the Plano Clima, with an integrated co-mitigation of GHGs and SLCPs approach. The work will be conducted under the coordination of the Plano Clima Senior Technical Coordinator, following general guidance from the Ministry of Environment and Climate Change as well as the CCAC and UNEP, and specific guidance from the respective focal point of the Ministry leading the Sectoral Plan. As a result of the elaboration of the Brazilian National Climate Plan, it is expected that the proposed sectoral plan provides a clear set of actions in the TRANSPORTATION sector to be implemented by the government for aligning the Brazilian economy towards a trajectory consistent to the targets defined. The sectoral plan should be integrated to a robust implementation strategy and Monitoring and Evaluation (M&E) framework. Detalhes no link: https://lnkd.in/duikUXXY

#QTNano: Algorithms for Acceleration of Materials Discovery Recently, I presented a talk at the SBQ meeting (Águas de Lindóia), where I emphasized the importance of improving the training of Brazilian chemistry students in the basic and modern concepts of data analysis and machine learning prediction. Here are some key considerations for addressing the challenges: 1. Integrating Algorithms and Programming into Chemistry Education: Both undergraduate and graduate chemistry curricula should include courses on algorithms and programming skills. It is essential for all students to be proficient in using standard algorithms to analyze and interpret their data effectively. 2. Digital Transformation of Experimental Laboratories: There is a need to transition from traditional paper lab notebooks to digital books and culture to implement local databases to organize group data. This shift can significantly enhance data management and analysis using computational tools, leading to more efficient and accurate research processes. There are open-access softwares to develop this task. 3. Automatic Literature Exploration: The sheer volume of scientific literature, often exceeding thousands of papers, requires the development of knowledge discovery databases. These databases can facilitate the automatic exploration and organization of literature, making it easier for researchers to stay updated and identify relevant studies. 4. Selecting the Best Algorithms for Specific Problems: Collaborating with computer science experts is crucial for selecting the most appropriate algorithms for various research problems. These collaborations can provide valuable insights and enhance the effectiveness of data analysis and predictive modeling. 5. Forming Multidisciplinary Teams: Optimizing and discovering new materials for specific applications necessitates multidisciplinary teams. These teams should include members with high-level scientific management skills to coordinate scientific efforts and achieve the best possible outcomes. Additional actions are required, however, the present list was discussed based on the Brazilian education environment context.

Extreme weather events are already a reality in many countries, including mine. The losses in the face of this calamitous situation are immeasurable. Dealing with and managing catastrophes like these goes beyond implementing risk mitigation policies, adaptation measures, and resilience programs. Society needs to change how it operates. As Marina Silva said, 'It's not enough to mitigate and adapt; we must transform.' And this is part of the story we need to tell. More than 700,000 people have been impacted. Over 65% of cities in Rio Grande do Sul have been affected. The more we educate ourselves about the consequences of climate change and approach it with the necessary seriousness and financial commitment, the better prepared we'll be to address its impacts. #SOSRS #RioGrandeDoSul #PublicCalamity #ClimateCrisis #Brasil

Artigo Publicado - Qualis CAPES A1 https://lnkd.in/d34WHaFe Publicamos mais um artigo de reologia, com foco no licor negro de celulose. Publicado na Nature - Scientific Reports: Classificação Qualis CAPES A1. Parabens a toda equipe envolvida neste trabalho. Abstract Black liquor (BL) is the major bioproduct and biomass fuel in pulp mill processes. However, the high viscosity of BL makes it a challenging material to work with, resulting in issues with evaporators and heat exchangers during its transport and processing. The thermal and rheological properties of BLs from Pinus sp. (PBL) and Eucalyptus sp. (EBL) were studied. FTIR spectra revealed the presence of the characteristic functional groups and the chemical composition in liquors. TGA/DTG curves showed three characteristic degradation stages related to evaporation of water, pyrolysis of organic groups, and condensation of char. Rheologically, liquors are classified as non-Newtonian and with comportment pseudoplastic. Their rheological dynamic shear properties included a linear viscoelastic region up to 1% shear strain, while frequency sweeps showed that storage modulus (G') > loss modulus (G''), thus confirming the solid-like behavior of both BLs. The rheological study demonstrated that increasing the temperature and oscillatory deformations of PBL and EBL decreased their degree of viscoelasticity, which could favor their pumping and handling within the pulp mill, as well as the droplet formation and swelling characteristics in the recovery furnace.

I am thrilled to announce that I will be presenting a seminar alongside my colleagues and advisor at the Oxford Department of International Development. Our discussion will focus on the critical role of governance, anthropology, engineering, and education in an interdisciplinary context for a just energy transition in the Amazon. Abstract: “The Amazon faces substantial challenges in terms of access to sustainable and clean energy, where the prevalence of diesel generators underscores the urgent need for renewable alternatives. In this context, the State University of Campinas (UNICAMP) in Brazil has taken a leading role with its Sustainable Campus Project, which incorporates the MERGE projects and the Interdisciplinary Program Eyes on the Future. MERGE focuses on the development and implementation of renewable energy microgrids, aiming for a more efficient and sustainable energy supply. Concurrently, Eyes on the Future seeks to promote education for a just energy transition and youth leadership for the conscious use of energy, empowering young people and promoting decent work aligned with the Sustainable Development Goals (SDGs).”
