Machine learning Hubbard parameters with equivariant neural networks
Published 2025-01-01“…Abstract Density-functional theory with extended Hubbard functionals (DFT + U + V) provides a robust framework to accurately describe complex materials containing transition-metal or rare-earth elements. It does so by mitigating self-interaction errors inherent to semi-local functionals which are particularly pronounced in systems with partially-filled d and f electronic states. …”

Analysis on the Difference of Impact Response between Single Coal-Rock Particle and the Box Structure-Based Tail Beam
Published 2021-01-01“…Firstly, through the construction and analysis of the impact theoretical model of the coal-rock particle and metal plate, it is found that the complex box structure of the tail beam makes it extremely difficult to establish the impact theoretical model of the coal-rock and box structure-based tail beam, so it is impossible to directly study the response of the box structure-based tail beam when the coal-rock impacts on the box structure-based tail beam by the theoretical method. …”

Uso de compostos de nióbio como catalisadores na produção de biocombustíveis: uma revisão
Published 2022-01-01“…Duas das principais contribuições para essa inviabilidade são o baixo desempenho dos processos (baixa conversão da matéria-prima e baixa seletividade dos produtos de interesse) e o alto custo dos catalisadores, que muitas vezes são feitos de metais nobres de pouca disponibilidade. O Nióbio é um metal com diversas aplicações, mas ainda pouco explorado industrialmente como catalisador, apesar de possuir propriedades interessantes para essa finalidade. …”
