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…

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…
