The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.

Highly Dynamic Soft Electrohydraulic Origami Actuators for Agile and Multimodal Robotic Locomotion
Most current soft robots still lag far behind their natural counterparts in both agility and speed, mainly attributed to the limited morphing modes and performance of soft actuators. Here, the authors report a new methodology of electrohydraulic origami (EHO) for creating powerful and multimodal soft actuators with large strain, high speed, lightweight,

A numerical investigation using 3D RANS simulations demonstrates significant effects of protuberance geometry—cubic, cylindrical, spherical, and conical—on shock‐induced thrust vectoring in supersonic nozzles. Cubic protuberances provide the maximum jet deflection (˜2°) with negligible thrust reduction.
