On Liquid Metal Wetting of Casting Rings for DC Casting

During air–slip direct chill casting of aluminum alloys, uneven or low air pressure areas at the surface of the porous graphite ring mold, can cause the metal to stick to the graphite ring and produce traces along the billets called vertical drags (VD). To prevent this type of defect, it would be an advantage to decrease the wettability of the graphite ring. It has been shown that nanostructure...

Casting NETs for microbes

E ven death doesn't stop a neutrophil from battling pathogens, as Fuchs et al. report on page 231. The infection-fi ghting cells often launch a neutrophil extracellular trap (NET), a mesh of DNA and enzymes that snares and kills bacteria and fungi. The authors show that NET release involves a unique type of cellular self-sacrifi ce and depends on reactive oxygen species (ROS). The standard way ...
