Investigating the influence of trace tantalum on the microstructure and mechanical properties of niobium microalloyed steels

Abstract: The global production of niobium-microalloyed steels is now a well-established industrial practice. Initially driven by experimental insights into niobium’s ability to refine steel microstructures during thermomechanical processing, this technology has become especially prevalent in low-alloy steels. An important aspect of niobium’s production is its natural association with tantalum, which Leia mais…

Efeito da morfologia do pó na desinficação e microestrutura de Nb₂O₅ sinterizado = Effect of powder morphology on densification and microstructure of sintered Nb₂O₅

Resumo: O Nb₂O₅ é amplamente utilizado em capacitores cerâmicos, sensores, células solares, prótesesbiocompatíveis e materiais fotocatalíticos. A sinterização é essencial para o desenvolvimentodas propriedades finais e depende fortemente da morfologia, do tamanho de partícula e dadistribuição granulométrica do pó. A atomização por spray dryer pode gerar pós commorfologia esferoidal e Leia mais…

Functional cargo in membrane vesicles from a citrus pathogen

Abstract: The causative agent of citrus canker disease, Xanthomonas citri pv. citri, was found to produce copious amounts of outer membrane vesicles (OMVs), frequently forming long membranous tubes under different culture conditions. Lipidomic analysis revealed significant differences in lipid composition between purified vesicles in relation to whole cells. The results suggest an enrichment Leia mais…
